Stem Cell Assays Market worth $4.5 billion by 2027 - Exclusive Report by MarketsandMarkets - PR Newswire

Belzutifan (Welireg), a hypoxia-inducible factor-2 alpha (HIF-2) inhibitor, demonstrated positive results when given as treatment to patients with Von Hippel-Lindau (VHL) disease and renal cell carcinoma (RCC).1,2

Previously, in August 2021, belzutifan was approved by the FDA for adult patients with VHL disease who require therapy for RCC, central nervous system (CNS) hemangioblastomas, or pancreatic neuroendocrine tumors not requiring immediate surgery.3 Since its approval, multiple studies examining the HIF-2 inhibitor have begun and made strides in the VHL and RCC spaces, including LITESPARK-001 (NCT02974738), LITESPARK-004 (NCT03401788), and LITESPARK-022 (NCT05239728).

At the 2022 American Society of Clinical Oncology (ASCO) Annual Meeting, Eric Jonasch, MD, presented the findings of both the phase 1 LITESPARK-001 and phase 2 LITESPARK-004 studies which examined belzutifan in different patient populations.1,2

In LITESPARK-001, the efficacy and safety of belzutifan in addition to pembrolizumab (Keytruda) vs the combination of placebo plus pembrolizumab was compared as treatment in patients with clear cell RCC (ccRCC) post nephrectomy. LITESPARK-004, an open-label, phase 2 study, evaluated the efficacy and safety of belzutifan in patients with VHL disease.

While these recent studies of belzutifan continue to show promise and investigators are able to prolong survivalsomething that was not demonstrated 10 years agounmet needs remain in this space. According to Jonasch, his hope is to be able to provide patients with a complete and durable response.

In an interview with Targeted OncologyTM, Jonasch, a professor in the Department of Genitourinary Medical Oncology, Division of Cancer Medicine at The University of Texas (UT) MD Anderson Cancer Center, further discussed the 2 posters he presented in regard to belzutifan at 2022 ASCO.

Can you describe the posters you presented at ASCO this year?

Jonasch: There were 2 posters on belzutifan, which is a HIF-2 inhibitor. This is a drug that has arisen out of several decades of work, starting with the discovery of the VHL gene in 1993, then with work by doctors Peter Ratcliffe, Gregg Semenza, and William Kaelin that the led to the Nobel Prize in 2019 of how VHL regulates HIF-1 and HIF-2. This then led to the efforts to target HIF as a treatment target, the challenge there being that small molecule inhibitors of transcription factors are historically hard to develop.

The team at UT Southwestern came up with an initial foray into that which then led the development of a company called Peloton that created the precursor drugs and the current drug that is now known as belzutifan and the trials that that we presented the updates on at ASCO. They're called the LITESPARK-001 spark, which is looking at the phase 1b/2 study in RCC, and LITESPARK-004, which is the registrational study and VHL disease, which led to the approval of belzutifan in VHL disease.

Could you discuss the background and the basis of LITESPARK-001?

LITESPARK-001 is a phase 1b/2 study, which did dose-escalation to find the optimal dose of belzutifan and focused on the RCC patient population. Fifty-five patients with RCC were enrolled in this trial.

The primary end point was safety with the phase 1 study and the secondary end points were progression-free survival [PFS], objective response rate [ORR], and duration of response per RESIST 1.1. The trial was a multicenter study, and we accrued these patients relatively rapidly. This presentation is now a median 41-month follow-up of data that we have previously published.

What safety and efficacy findings were discovered in LITESPARK-001 for patients with RCC?

What was exciting was that both from a safety perspective, as well as from an efficacy perspective, the data continue to hold up. Safety shows that anemia was the most common adverse event in the metastatic advanced RCC, at 24%, patients who did have grade 3 anemia. This is an on-target effect because HIF-2 is the transcription factor that regulates urethral potent. So if you knock down HIF-2, you would expect less production, and indeed, that's what happened. This is something that's manageable either with exogenous erythropoietin blood transfusions, or dose adjustments.

Hypoxia is a relatively rare adverse event and about 13% of individuals developed that as well. Unclear mechanism, but something that's also quite manageable with dose adjustments. From an ORR perspective, we see that this has continued to hold up. The ORR in this follow-up of 41 months is 25%, as it was before, and there are some subset analyses that have been formed looking at whether or not this is different in favorable vs intermediate and poor risk. It really doesn't look like there's a major difference, it's 31% in the favorable vs 24% in the intermediate/poor risk.

The other thing we looked at was the 3 prior therapies received in this patient population, so heavily pretreated. Those who did not receive either prior IO [immunotherapy] or VEGF [inhibition], the ORR was 38%. For those who had received prior IO and VEGF, the ORR was 21%. Again, small numbers in this but still very interesting to see that this is quite effective, regardless of what prior therapies people have received.

The median PFS was 14.5 months, so from a metastatic RCC perspective, we're seeing that even as a single agent in this heavily pretreated patient population, the data continue to hold up that this drug those who defend it is active in this patient population. I'm looking forward to seeing this being an approved agent and advanced renal cell carcinoma.

What did you look at in LITESPARK-004?

LITESPARK-004 is in patients with VHL disease, and we did get approval for belzutifan in patients with VHL disease. The basis of this 61-patient study, which was published last year in the New England Journal of Medicinebut this is an immediate 29-month follow-up. With the metastatic RCC patient population, we're seeing that these data not only are holding up but they're improving with time.

The primary end point was ORR in RCC from these patients. We're seeing now that those numbers have gone up to an ORR of 59%. There is now a 3% CR [complete response] rate and a 56% partial response rate, so even better than we've seen before.

We see that of the number of patients that remain on study with nearly 30 months follow-up, 50 out of 61 patients remain on study and only 4 patients came off because of a progressive disease. Even more excitingly, we're seeing that RCCs are responding with pancreatic lesions. There's an 80% ORR. If you look at pancreatic neuroendocrine tumors, it's a 90% response rate. For CNS hemangioblastomas, there's now a 38% response rate and we're seeing CRs in all of these.

What do these findings mean for this patient population?

This is really amazing for this group of individuals who face a lifetime of surveillance, imaging, surgical intervention for these lesions as they reach various danger points. We are seeing, already in the study, that for those individuals who were on this trial across the population of study, there were about 20 procedures per year being performed on these patients. Since getting on the study in the entire population, there have only been 3 procedures. This is really game changing in terms of how many surgical procedures these patients have to be subjected to after starting those effects.

How do you think the findings of both LITESPARK-001 and LITESPARK-004 will impact the future of this space?

For patients with VHL, I think it's going to be a question of what is the ideal patient? When should we use this study? In the LITESPARK-004 study, there were no brakes built into the study, so should we treat it to maximal benefit and then take breaks? We don't know. Should we be starting this in patients as a prevention strategy? Obviously, a clinical study would have to be designed to do that. These are the sorts of questions that are being asked in the VHL world.

What are the determinants of resistance? Again, there's so few patients that have demonstrated resistance. It's hard at this point in time to answer that, but I think it's going to become easy. Unfortunately, it is easier as more people inevitably progress. I think for advanced RCC, the big questions are, how do we use this drug optimally? Do we use it as monotherapy, which I think is already likely to be effective, but can we improve this by adding a tyrosine kinase inhibitor or by adding IO? What should we be doing to really optimize the use of this drug?

Is belzutifan currently being examined in any other spaces?

It is being tested in other diseases. As of now, at least in the data that we have, there have not been extremely strong signals elsewhere. I think that is more due to a lack of data as opposed to a clear sign that it's not effective. I think the next steps are going to be finding the ideal combination [and] determining how to optimally use this drug in conjunction with other agents in the treatment landscape.

What unmet needs still exist in the advanced renal cell carcinoma space?

We need curative therapy. We are getting better at prolonging survival, which was something that 10 years ago wasn't even consistent, so we're getting there with regards to improving survival. But what we want is to be able to get people to have a CR that is durable, where we can even stop therapy for a while and allow them to enjoy a treatment-free interval. That is the new Holy Grail. Ten years ago, saying CRs would be our goal was perhaps fanciful, but now because we're seeing that in a small but significant group of patients, I think that is what we should be pushing forward to get. [And getting] that depth of response and to get that durability of response so we can have people living much longer.

What would you recommend for community oncologists working with patients in these patient populations?

If you have patients with VHL disease in your practice, my recommendation is that you work together with the clinical care centers that are around the country to optimize the management of these individuals.

For patients with advanced RCC in your practice, I would say stay tuned. This is not yet FDA approved for that indication, but I am really hopeful to see this as a choice for advanced RCC in the relatively near future.

Immatics and Editas Medicine Enter Strategic Research Collaboration and Licensing Agreement to Combine Gamma-Delta T Cell Adoptive Cell Therapies and...

For years, the American Society of Clinical Oncologys annual meeting has served as the main forum for advances in cancer immunotherapies like Merck & Co.s Keytruda and Bristol Myers Squibbs Opdivo.

While new data continue to emerge for those drugs and their competitors, this years conference was headlined by dramatic data for another type of cancer medicine from AstraZeneca and Daiichi Sankyo, which put pressure on rival Gilead. And with CAR-T therapies now established, attention has shifted to other emerging approaches for training the immune system to attack tumors.

Read on for updates on Gilead, bispecific antibodies for blood cancer and gamma delta cell therapy.

ASCO is an important conference for any biotech developing a cancer drug. But this years meeting was particularly so for Gilead, which has spent a decade and billions of dollars trying to build its oncology business. Analysts and investors were eagerly awaiting the details of a key study of the breast cancer drug Trodelvy, for which it paid $21 billion to acquire last year. Updates were also expected for magrolimab, another cancer medicine Gilead recently bought in a large deal.

The drugs either underwhelmed or were upstaged by others, however. Trodelvy led to a 1.5-month improvement over chemotherapy on a measure of tumor progression in a late-stage study of patients with a common form of metastatic breast cancer. The result fell short of the 2-month target doctors surveyed by analyst firm RBC Capital Markets felt would warrant meaningful use, according to a research note.

Trodelvy was also overshadowed by AstraZeneca and Daiichi Sankyos rival breast cancer drug, Enhertu, whose data in so-called HER2 low tumors were so striking they received a standing ovation at the meeting.

All the enthusiasm for Trodelvy has evaporated after those results, wrote Baird analyst Brian Skorney in a note on Sunday, adding that Enhertus likely approval in HER2 low breast cancer could limit Trodelvys revenue potential.

Analysts were similarly unimpressed by the latest data for magrolimab, a blood cancer drug that was slowed by safety concerns this year. Initial data showed a response rate of 50% for a combination of magrolimab and the chemotherapy azacitidine in an early-stage trial in myelodysplastic syndrome. That rate has fallen to 33% with additional data, barely surpassing whats been observed in tests of chemotherapy alone, Skorney wrote.

Complete response rates slipped in a Phase 1 acute myeloid leukemia study as well. The updates show Gileads drug has sufficient activity, though its perhaps not the home run it was initially hoped to be, wrote RBC analyst Brian Abrahams in a note to clients.

Gilead will likely need to show more before investors view the cancer portfolio as a major growth driver, Abrahams added. Shares ticked down 2% in early Monday trading.

The biotech did get a reprieve on Friday, however, announcing that regulators had lifted their last remaining hold on studies of magrolimab in lymphoma and multiple myeloma.

Cell therapy has become a powerful new treatment option for blood cancers like lymphoma and multiple myeloma. Approved drugs from Gilead, Bristol Myers Squibb, Novartis and Johnson & Johnson use souped-up immune cells genetically modified and infused back into patients to attack cancers.

But the approach, while potent, involves a painstaking manufacturing process that requires physicians to carefully time treatment. In multiple myeloma, Bristol Myers and J&J have struggled to keep up with demand, Stat News has reported, further complicating cell therapy's use.

While drugmakers expect to overcome those hurdles with time, they are busy advancing other ways to redirect immune cells to target cancer. One alternative uses an antibody to latch onto protein flags found on the surface of immune cells and their cancerous targets, bringing them into tumor-killing contact.

These so-called bispecific antibodies have already shown promise in some of the same blood cancers addressed by CAR-T cell therapies. At ASCO, Roche and J&J revealed updated clinical trial data supporting their respective medicines for lymphoma and multiple myeloma. AbbVie and partner Genmab, meanwhile, will present data on their lymphoma bispecific antibody at the European Hematology Association's meeting next weekend.

Scott Gottlieb, formerly Food and Drug Administration commissioner and currently a member of Pfizers board, pointed to bispecific antibody data as some of the most exciting to come out of ASCO this year.

"That data looks very promising," he said on CNBCs Squawkbox program Monday, noting the therapies from Roche and partners AbbVie and Genmab specifically.

Specifically, Roche's data showed treatment led to responses in half of patients with relapsed or refractory diffuse large B-cell lymphoma who were treated in the study. Nearly 40% went into remission.

Notably, about a third of the 154 participants had previously received CAR-T therapies, which have recently been approved in the U.S. for earlier use in treating advanced lymphoma.

"We still need longer follow-up for the bispecific antibodies," said Kerry Savage, a medical oncologist at The University of British Columbia, who discussed Roche's abstract at ASCO on Friday. "We don't know the curative potential yet, but it's certainly encouraging so far."

AbbVie and Genmab's results, which will be presented on Saturday at EHA, showed a slightly higher overall response rate of 63% and a similar remission rate of 39% among adults with several variations of relapsed or refractory large B-cell lymphoma.

J&J, meanwhile, brought updated data to ASCO for its multiple myeloma bispecific teclistamab, which were also published in The New England Journal of Medicine. The data showed treatment could beat back cancer and, in about 40% of patients, lead to remission.

"The high rate of deep and durable responses in this population indicates the potential for teclistamab to provide substantial clinical benefit to a broader population of patients," researchers wrote in NEJM.

The search for more convenient alternatives to personalized cell therapies has led to other off-the-shelf strategies besides bispecific antibodies. One emerging approach involves gamma delta T cells, rare white blood cells that can recognize a range of targets.

Adicet Bio, In8Bio, Immatics, among others, are developing treatments and multiple large companies have shown interest in their work. Bristol Myers Squibb just last week expanded an existing deal with Immatics, while Takeda and Johnson & Johnson have recently made investments, too.

Adicets program, a potential treatment for non-Hodgkins lymphoma, is the most advanced of the group, making its trial results an important proof point for the field.

Prior to the meeting, Adicet said four of six treated patients with a low or medium dose went into remission, with two of the three patients treated still cancer free after three months. Importantly, there were no serious immune or neurological side effects reported.

At ASCO, Adicet disclosed results from two additional patients as well as longer follow-up from others. While early, the findings are in the range with CAR-T therapy. As of May 31, six of eight patients including two at the highest tested dose had responded to treatment. All six initially went into remission.

Notably, these were heavily pretreated patients, three of whom whose disease had progressed after CAR-T. Adicet hasnt reported any cases of severe cytokine release syndrome, a common side effect of CAR-T.

Yet the treatments durability remains in question. Though four of the complete responses are ongoing, only one has lasted longer than six months. One patient previously in remission died from COVID-19, while another relapsed.

Adicet plans to pick a dose to advance into further testing. The company amended its trial to include a higher dose as well as potentially evaluate a multiple-dose regimen, a strategy other off-the-shelf cell therapy developers are testing as well.

An acceptable safety profile and durable complete response (CR), partial response (PR) rates were observed with the chimeric antigen receptor (CAR) T-cell therapy CTX130 in the phase 1 COBALT-LYM study of patients with relapsed/refractory T-cell lymphomas, said Swaminathan P. Iyer, MD, professor of medicine in the Department of Lymphoma and Myeloma at the University of Texas MD Anderson Cancer Center.

Iyer served as lead author of a study presented today at the 2022 European Hematology Association (EHA) Congress, titled, "The COBALT-LYM Study of CTX130: A Phase 1 Dose Escalation Study of CD70-Targeted Allogeneic CRISPR-Cas9Engineered CAR-T Cells in Patients with Relapsed/Refractory (R/R) T-cell Malignancies.

Transcript

What is the mechanism of action for CTX130 in T-cell lymphoma, and can you discuss how the COBALT-LYM study was conducted?

So, CTX130 is a first-in-class allogeneic CAR T-cell for T-cell lymphomas. And the study that put together this CAR T was called the COBALT-LYM study, and the target here is CD70, [which] is a protein that is expressed on the surface of cells. It's been found that 85% of T-cell lymphomas express them.

A lot of investigations of the past have been done on CD70 in terms of antibodies and antibody drug conjugates. What's different about this construct, it's an allogeneic CAR T, which means healthy donors are selected and the chimeric antigen receptor is created using CD70 as a construct, and using the other activation and costimulatory domains.

This is the product, CTX130, and this a phase 1 dose-finding study allowable in patients who express at least greater than 10% of CD70 in patients with PTCL [peripheral t-cell lymphoma] and patients with CTCL [transformed cutaneous t-cell lymphoma]. For PTCL, the prior criteria is one prior line of therapy, for CTCL its at least 2 systemic therapies.

The patients were enrolled, and you will see the presentation this afternoon, from the abstract, it's 18 patients data who participated in this study, and 70% overall response rate and 29% CR based on the abstract. So, this is the CTX130, and there's more data that will be presented this afternoon.

Can you discuss efficacy and safety findings reported at EHA2022 of the COBALT-LYM study?

So, the first thing is safety. Since it's a dose-finding study, phase 1, the main goal of part A, which is the dose escalation, is safety. Since it's a CAR T construct, it has certain potential side effects that are very different from other drugs, if you will.

So, the things that you would expect in CAR Ts are cytokine release syndrome [CRS], the neurological toxicity called ICANS [immune effector cell-associated neurotoxicity syndrome], and since its an allogeneic CAR T, GVHD [graft versus host disease], and since it's an effective therapy, tumor lysis syndrome (TLS), and then everything else that other drugs might cause.

So, in this particular study, the safety was acceptable across all those levels4 of those levels tested, 1, 2, 3, and 4, going from 30 to 900 million cells, and the safety was acceptable. The CRS was mostly grade 1 and 2, the neurological toxicity was grade 1 and 2, all of which resolved. There was no TLS, no GVHD.

There were some infections seen. One out of the 4 infections of the grade 3 or higher were attributable to the CAR T, but otherwise, there are other treatment-emergent SAEs [serious adverse events], such as syncope, presyncope, tumor hemorrhagethey were all not deemed related to CTX130. So, safety wise, very acceptable.

Efficacy, I just mentioned 70% overall response rate with 29% CRs. And some of these CRs were durable CRs. You will see that many of them could be bridged to the more longer-term consolidation therapy. But for the first time you're seeing responses in T-cell lymphomas, patients who did not achieve prior responses like a CR, and now we're getting to the point where you have PRs and CRs that are lasting.

BOSTON--(BUSINESS WIRE)--Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today announced that five scientific abstracts on the companys portfolio of cystic fibrosis (CF) medicines will be presented at the European Cystic Fibrosis Society's (ECFS) 45th European Cystic Fibrosis Conference held June 8-11, 2022, in Rotterdam, the Netherlands.

Vertex will present the first analysis of data collected in the U.S. CF Foundation Patient Registry (CFFPR) of over 16,000 people with CF treated with TRIKAFTA (elexacaftor/tezacaftor/ivacaftor and ivacaftor) for an average of nine months. This first interim analysis of an ongoing five-year post-authorization study (abstract WS22.05) showed that real-world treatment with TRIKAFTA was associated with improved lung function and a 77% reduced risk of pulmonary exacerbations compared to pre-TRIKAFTA baseline, as well as an 87% lower risk of lung transplant and a 74% lower risk of death, compared to the historical 2019 U.S. CFFPR population. No new safety concerns were identified.

Vertex will also present data comparing the annual rate of lung function change in people with CF ages 12 years and older with two F508del mutations (F/F) or one F508del mutation and one minimal function mutation (F/MF) treated with TRIKAFTA in pivotal studies and an open-label extension study compared to propensity-score matched historical CFTR-modulator-untreated controls from the U.S. CFFPR (abstract WS22.04). Results show that TRIKAFTA demonstrated on average no decrease in ppFEV1 over a two-year period in this population, in contrast to declines seen in the matched controls. The analysis indicates that treatment with TRIKAFTA has a significant impact on the trajectory of CF lung disease.

Additionally, Vertex will present data from a long-term real-world study demonstrating that initiating KALYDECO (ivacaftor) early in life (ages 6-10 years) preserves lung function to a greater extent than if KALYDECO is initiated at an older age (abstract WS17.03). These results show the importance of early initiation of KALYDECO for eligible patients.

These long-term and real-world studies show the potentially transformative benefits of treatment with CFTR modulators and add to the substantial body of evidence supporting treatment as early in life as possible, said Carmen Bozic, M.D., Executive Vice President, Global Medicines Development and Medical Affairs, and Chief Medical Officer at Vertex. We continue to make rapid progress in developing medicines that treat the underlying cause of CF, and today, we are closer to our goal of developing highly effective therapies for all patients with CF than ever before.

Additional Presentations

In addition to the studies noted above, other Vertex presentations at the conference this year support the long-term and early use of CFTR modulators:

About Cystic Fibrosis

Cystic fibrosis (CF) is a rare, life-shortening genetic disease affecting more than 83,000 people globally. CF is a progressive, multi-organ disease that affects the lungs, liver, pancreas, GI tract, sinuses, sweat glands and reproductive tract. CF is caused by a defective and/or missing CFTR protein resulting from certain mutations in the CFTR gene. Children must inherit two defective CFTR genes one from each parent to have CF, and these mutations can be identified by a genetic test. While there are many different types of CFTR mutations that can cause the disease, the vast majority of people with CF have at least one F508del mutation. CFTR mutations lead to CF by causing the CFTR protein to be defective or by leading to a shortage or absence of CFTR protein at the cell surface. The defective function and/or absence of CFTR protein results in poor flow of salt and water into and out of the cells in a number of organs. In the lungs, this leads to the buildup of abnormally thick, sticky mucus, chronic lung infections and progressive lung damage that eventually leads to death for many patients. The median age of death is in the early 30s.

About TRIKAFTA (elexacaftor/tezacaftor/ivacaftor and ivacaftor)

In people with certain types of mutations in the CFTR gene, the CFTR protein is not processed or folded normally within the cell, and this can prevent the CFTR protein from reaching the cell surface and functioning properly. TRIKAFTA (elexacaftor/tezacaftor/ivacaftor and ivacaftor) is an oral medicine designed to increase the quantity and function of the CFTR protein at the cell surface. Elexacaftor and tezacaftor work together to increase the amount of mature protein at the cell surface by binding to different sites on the CFTR protein. Ivacaftor, which is known as a CFTR potentiator, is designed to facilitate the ability of CFTR proteins to transport salt and water across the cell membrane. The combined actions of elexacaftor, tezacaftor and ivacaftor help hydrate and clear mucus from the airways.

TRIKAFTA is a prescription medicine used for the treatment of cystic fibrosis (CF) in patients aged 6 years and older who have at least one copy of the F508del mutation, or another mutation responsive to TRIKAFTA, in the CFTR gene. Patients should talk to their doctor to learn if they have an indicated CF gene mutation. It is not known if TRIKAFTA is safe and effective in children under 6 years of age.

Please see Important Safety Information below and [click here] for full U.S. Prescribing Information.

About KALYDECO (ivacaftor)

In people with certain types of mutations in the CFTR gene, the CFTR protein at the cell surface does not function properly. Known as a CFTR potentiator, ivacaftor is an oral medicine designed to facilitate the ability of CFTR proteins to transport salt and water across the cell membrane, which helps hydrate and clear mucus from the airways. KALYDECO (ivacaftor) was the first medicine to treat the underlying cause of cystic fibrosis (CF) in people with specific mutations in the CFTR gene.

KALYDECO is a prescription medicine used for the treatment of CF in patients aged 4 months and older who have at least one mutation in their CF gene that is responsive to KALYDECO. Patients should talk to their doctor to learn if they have an indicated CF gene mutation. It is not known if KALYDECO is safe and effective in children under 4 months of age.

Please see Important Safety Information below and [click here] for full U.S. Prescribing Information.

About ORKAMBI (lumacaftor/ivacaftor)

In people with two copies of the F508del mutation, the CFTR protein is not processed and trafficked normally within the cell, resulting in little to no CFTR protein at the cell surface.

ORKAMBI (lumacaftor/ivacaftor) is an oral medicine that is a combination of lumacaftor and ivacaftor. Lumacaftor is designed to increase the amount of mature protein at the cell surface by targeting the processing and trafficking defect of the F508del-CFTR protein. Ivacaftor, which is known as a CFTR potentiator, is designed to facilitate the ability of CFTR proteins to transport salt and water across the cell membrane. The combined actions of lumacaftor and ivacaftor help hydrate and clear mucus from the airways.

ORKAMBI is a prescription medicine used for the treatment of CF in patients age 2 years and older who have two copies of the F508del mutation (F508del/F508del) in their CFTR gene. ORKAMBI should only be used in these patients. It is not known if ORKAMBI is safe and effective in patients under 2 years of age.

Before taking KALYDECO, ORKAMBI, or TRIKAFTA patients should tell their doctor about all of their medical conditions, including if they: have or have had liver problems; have kidney problems; are pregnant or plan to become pregnant because it is not known if KALYDECO, ORKAMBI, or TRIKAFTA, will harm an unborn baby; or are breastfeeding or planning to breastfeed because it is not known if KALYDECO, ORKAMBI, or TRIKAFTA passes into breast milk. Before taking ORKAMBI, patients should tell their doctor if they have had an organ transplant, or if they are using a hormonal contraceptive including oral, injectable, transdermal, or implantable form as this should not be used as a method of birth control when taking ORKAMBI.

KALYDECO, ORKAMBI, or TRIKAFTA may affect the way other medicines work, and other medicines may affect how KALYDECO, ORKAMBI, or TRIKAFTA work. Therefore, the dose of KALYDECO, ORKAMBI, or TRIKAFTA may need to be adjusted when taken with certain medications. Patients should especially tell their doctor if they take antifungal medications such as ketoconazole, itraconazole, posaconazole, voriconazole, or fluconazole; or antibiotics such as telithromycin, clarithromycin, or erythromycin.

KALYDECO or TRIKAFTA can cause dizziness in some people who take it. Patients should not drive a car, use machinery, or do anything that needs them to be alert until they know how KALYDECO or TRIKAFTA affects them.

When taking ORKAMBI, patients should tell their doctor if they stop taking ORKAMBI for more than 1 week as their doctor may need to change the dose of ORKAMBI or other medicines the patient is taking.

Patients should avoid food or drink containing grapefruit while taking KALYDECO or TRIKAFTA.

KALYDECO, ORKAMBI, and TRIKAFTA can cause serious side effects, such as:

Liver damage and worsening of liver function in people taking TRIKAFTA with severe liver disease that can be serious and may require transplantation. Liver damage has also happened in people without liver disease.

High liver enzymes in the blood have been reported in patients receiving KALYDECO, ORKAMBI, or TRIKAFTA. The patient's doctor will do blood tests to check their liver before starting treatment with KALYDECO, ORKAMBI, or TRIKAFTA; every 3 months during the first year of treatment; and every year while on treatment. For patients who have had high liver enzymes in the past, the doctor may do blood tests to check the liver more often. Patients should call their doctor right away if they have any of the following symptoms of liver problems: pain or discomfort in the upper right stomach (abdominal) area; yellowing of their skin or the white part of their eyes; loss of appetite; nausea or vomiting; or dark, amber colored urine.

Worsening of liver function in people with severe liver disease taking ORKAMBI. The worsening of liver function can be serious or cause death. Talk to your doctor if you have been told you have liver disease as your doctor may need to adjust the dose of ORKAMBI.

Breathing problems such as shortness of breath or chest tightness in patients when starting ORKAMBI, especially in patients who have poor lung function. If a patient has poor lung function, their doctor may monitor them more closely when starting ORKAMBI.

An increase in blood pressure in some people receiving ORKAMBI. The patients doctor should monitor their blood pressure during treatment with ORKAMBI.

Abnormality of the eye lens (cataract) in some children and adolescents treated with KALYDECO, ORKAMBI, or TRIKAFTA. If the patient is a child or adolescent, their doctor should perform eye examinations before and during treatment with KALYDECO, ORKAMBI, or TRIKAFTA to look for cataracts.

The most common side effects of KALYDECO include headache; upper respiratory tract infection (common cold), which includes sore throat, nasal or sinus congestion, and runny nose; stomach (abdominal) pain; diarrhea; rash; nausea; and dizziness.

The most common side effects of ORKAMBI include breathing problems, such as shortness of breath and chest tightness; nausea; diarrhea; fatigue; increase in a certain blood enzyme called creatinine phosphokinase; rash; gas; common cold, including sore throat, stuffy or runny nose; flu or flu-like symptoms; and irregular, missed, or abnormal periods (menses) and increase in the amount of menstrual bleeding. Additional side effects seen in children include cough with sputum, stuffy nose, headache, stomach pain, and increase in sputum.

The most common side effects of TRIKAFTA include headache; diarrhea; upper respiratory tract infection (common cold), including stuffy and runny nose; stomach (abdominal) pain; inflamed sinuses; increase in liver enzymes; increase in a certain blood enzyme called creatine phosphokinase; rash; flu (influenza); and increase in blood bilirubin.

The longest duration of reduction in red blood cell transfusion dependence was reported among patients with -thalassemia who received continued treatment with luspatercept-aamt in the updated data from the phase 3 BELIEVE trial.

The longest duration of reduction in red blood cell (RBC) transfusion dependence was reported among patients with -thalassemia who received continued treatment with luspatercept-aamt (Reblozyl) in the updated data from the phase 3 BELIEVE trial (NCT02604433), presented at the 2022 EHA Congress.1

Response was assessed as reduction of RBC transfusion burden by at least 33% from baseline and by at least 50% from baseline among patients who received luspatercept vs placebo during any rolling 12- or 24-week interval. With a long-term data cutoff of January 5, 2021, among the 224 patients in the luspatercept arm, 173 patients (77.2%) had at least 33% response during any 12-week interval and 116 (51.8%) had a response during any 24-week interval. A transfusion burden reduction of at least 50% was reported among 112 patients (50%) and 53 patients (23.7%) during any 12- and 24-week interval, respectively.1

These outcomes were compared with prior data cutoff landmarks: May 11, 2018 (primary data cutoff) and January 7, 2019 (intermediate data cutoff). In the primary analysis, 70.5% and 41.1% of patients had at least a 33% reduction in transfusion burden at the 12- and 24-week intervals. These rates were 76.3% and 45.1% in the intermediate analysis, respectively. Reduction of at least 50% were reported at any 12- and 24-week intervals among 40.2% and 16.5% of patients, respectively, in the primary analysis and 44.6% and 20.5% in the intermediate analysis.1

In terms of transfusion independence, at the cutoff of 3 years 12% of patients [who received] luspatercept, achieved transfusion independence, equal to or more than [8] weeks. And that, of course, implies the longest interval of this condition of transfusion in dependence, said Maria Domenica Cappellini, MD, FRCP, FACP, professor of internal medicine at the University of Milan and chief of the Rare Diseases Centre at the Fondazione IRCCS Policlinico Hospital in Italy, during a presentation of the data.

The median longest duration of RBC transfusion independence was 72 days (95% CI, 62-103) with longer-term luspatercept treatment. At the primary and intermediate analysis cutoffs, the rates of RBC transfusion independence lasting at least 8 weeks were 10.7% and 11.2%, respectively, compared with 12.1% in the longer-term analysis.

Continuous treatment with the luspatercept allowed for more patients to experience a reduction in RBC transfusion burden, with longer durations of responses compared [with] the previous cutoff, Cappellini said. We are confident that these [benefits] will be even more clear with longer follow-up and patients with transfusion dependent -thalassemia treated in the BELIEVE study will continue to benefit from luspatercept with over 3 years of treatment.

Additional data showed that the median duration of RBC transfusion burden reduction was 114 days (95% CI, 107-137) and 99 days (95% CI, 95-104) for those with 33% reduction and 50% reduction, respectively, at the long-term analysis cutoff. In the primary data cutoff analysis, the median duration of RBC transfusion burden reduction was 104 days (95% CI, 84-588) for those with at least 33% reduction and 97.5 days (95% CI, 84-588) for those with at least 50% reduction. In the intermediate analysis the median duration was 105 days (95% CI, 84-825) and 99 days (95% CI, 84-825), respectively.

The median treatment duration during the primary, intermediate, and long-term landmark analyses were 64.1 days (95% CI, 3-97), 95.7 days (95% CI, 1.7-128.1), and 153.6 days (95% CI, 1.7-215).

Further, the mean cumulative duration of RBC transfusion burden reduction during any rolling 12-week interval was 627.3 (standard deviation, 390.5) for patients who received luspatercept.1

In terms of RBC transfusion burden change from baseline, Cappellini noted that patients receiving luspatercept required fewer units of blood over time. The mean change in RBC units every 48 weeks from baseline was 4.8 (weeks 1-48), 5.6 (weeks 49-96), 6.2 (weeks 97-144), and 6.4 (weeks 145-192) compared with a 1.1 unit increase reported in weeks 1-48 with placebo.

Cappellini also highlighted that patients achieving an RBC transfusion burden reduction of 50% or higher experienced a greater interval between the transfusions compared with the baseline over time at a mean of +9.9 days (standard deviation, 22.0).1

Luspatercept, an erthyroid maturation agent, is approved for the treatment of anemia in patients with -thalassemia who require regular red blood cell (RBC) transfusions. Additionally, it received an indication for patients who require 2 or more RBC units over 8 weeks for patients with very low- to intermediate-risk myelodysplastic syndromes (MDS) with ring sideroblasts or with MDS/myeloproliferative neoplasm with ring sideroblasts and thrombocytosis.2

BELIEVE was a randomized, double-blind, study comparing luspatercept with placebo.1,3 Investigators enrolled adults with -thalassemia who required regular transfusions of 6 to 20 RBC units in the 24 weeks prior to random assignment, with no transfusion-free period (35 days). Patients were randomly assigned 2:1 to luspatercept (n = 224) plus best supportive care or placebo plus best supportive care (n = 112). Luspatercept was administered subcutaneously 1.0 mg/kg (up to a maximum dose of 1.25 mg/kg) every 3 weeks. Best supportive care included RBC transfusions to maintain baseline hemoglobin levels and iron chelation therapy.1,3

The primary end point was reduction of RBC transfusion burden by at least 33% from baseline with a reduction of at least 2 units in weeks 13 to 24 compared with the 12 weeks prior to randomization.3

Baseline characteristics between the experimental and control arm were well balanced. The median age was 30 years (range, 18-66). Median hemoglobin levels at 24 weeks were 9.31 g/dL (range, 4.5-11.4) and 9.15 g/dL (range, 5.8-11.7) in the luspatercept arm and placebo arm, respectively. The median RBC transfusion burden was 6.12 units (range, 3-14) every 12 weeks in the luspatercept arm and 6.27 (range, 3-12) in the placebo arm. The median burden every 24 weeks was 14 units (range, 6-24) and 15 (range, 6-26), respectively. Further, over half of patients (57.6% and 58.0%, respectively) had a splenectomy.

In terms of liver iron concentration (LIC), at baseline the median LIC in the luspatercept arm was 6.4 mg/g dry weight (range, 0.8-125.0) and 5.05 mg/g dry weight (range, 0.2-53.2) in the placebo arm. An analysis of LIC is ongoing, according to Cappellini.

At data cutoff 127 patients (56.7%) remained on study treatment and 2.7% (n = 6) have completed 192 weeks of treatment. Of the 224 patients in the luspatercept arm, 96 (42.9%) discontinued treatment. The most common reasons for discontinuation were physician decision (23.7%), adverse event (10.3%), or other (5.4%).

Long-term Treatment With Luspatercept Reduces Transfusion Dependence Associated With -Thalassemia - OncLive

More than a dozen rectal cancer patients in the United States have seen their cancer disappear after undergoing experimental immunotherapy, in what doctors are calling an astonishing result.

The patients, who were part of a small clinical trial led by researchers from New Yorks Memorial Sloan Kettering (MSK) Cancer Center, saw their tumours vanish after being treated with an experimental drug called dostarlimab.

Details of the trial were published on Sunday in the New England Journal of Medicine.

The paper described the results of 12 patients with rectal cancer, all of whom saw their cancer vanish after treatment with dostarlimab.

Participants received a dose of dostarlimab every three weeks for six months, with the idea being that they would need to undergo standard treatments of chemotherapy, radiation therapy and surgery following treatment.

However, researchers found that in every case, the cancer was cleared through the experimental treatment alone.

The trial has been hailed as a first in cancer treatment, with one of the papers authors, Dr Luis Diaz Jr of Memorial Sloan Kettering, telling the New York Times that he knew of no other study in which a treatment completely obliterated a cancer in every patient.

I believe this is the first time this has happened in the history of cancer, he said.

Immunotherapy harnesses the bodys own immune system to identify and destroy cancer cells.

The trial focussed on a subset of rectal cancer patients whose cancer had a specific mutation, MSK said in a statement.

This sort of rectal cancer, known as "mismatch repair-deficient" (MMRd) rectal cancer, tends to respond poorly to standard chemotherapy regimens. In the trial, researchers wanted to investigate if immunotherapy alone could beat rectal cancer that had not spread to other tissues, the organisation said.

The research, which is ongoing, has seen at least 14 patients and counting have their tumours disappear, with none of them experiencing significant side effects, it added.

There was no need for standard treatments of radiation, surgery, or chemotherapy, and the cancer has not returned in any of the patients, who have been cancer-free for up to two years, it said.

Its incredibly rewarding to get these happy tears and happy emails from the patients in this study who finish treatment and realise, Oh my God, I get to keep all my normal body functions that I feared I might lose to radiation or surgery, said Dr Andrea Cercek of Memorial Sloan Kettering, who co-led the trial.

Inspiration for the study came from a previous trial led by Dr Diaz, which saw patients taking a drug called pembrolizumab, the New York Times reported. That trial, which involved patients with advanced cancer that resisted standard treatment, saw participants tumours stabilise, shrink and even vanish.

In the current trial, researchers wanted to see what a similar drug, dostarlimab, would do if used before the cancer cells had a chance to spread.

This sort of treatment focuses on particular proteins called checkpoints, which are made by some types of immune system cells as well as some cancer cells, according to the USNational Cancer Institute. The checkpoints, which keep immune responses from being too strong, can sometimes prevent immune cells from effectively killing cancer cells.

Like pembrolizumab, dostarlimab is a checkpoint inhibitor: It essentially releases the brakes on an immune cell, freeing it to recognise and attack cancer cells, according to MSK.

When the brakes are taken off the immune cells, MMRd cells look especially strange because they have so many mutations. So the immune cells attack with much more force, Dr Cercek said.

The results have provided what may be an early glimpse of a revolutionary treatment shift, Dr Hanna Sanoff, an oncologist at the Lineberger Comprehensive Cancer Center at the University of North Carolina, who was not involved in the trial, wrote in an editorial accompanying the paper.

However, she added that although the results are cause for great optimism, such an approach cannot yet supplant our current curative treatment approach.

Whether the results of this small study conducted at Memorial Sloan Kettering Cancer Center will be generalisable to a broader population of patients with rectal cancer is also not known, she said.

In order to provide more information regarding which patients might benefit from immunotherapy, subsequent trials should aim for heterogeneity in age, coexisting conditions, and tumour bulk.

The clinical trial is continuing to enrol patients and is growing, the MSK researchers said. They are also investigating to see if the same method can beat other cancers, and are looking at patients with gastric (stomach), prostate, and pancreatic cancers.

Karen L. Reckamp, MD, explains the need for more treatment options for patients with nonsmall cell lung cancer who have been previously treated with immune checkpoint inhibitors and develop resistance.

Karen L. Reckamp, MD, a professor in Medicine, and director of the Division of Medical Oncology at Cedars-Sinai Medical Center, as well as a medical oncologist at the Samuel Oschin Cancer Center, explains the need for more treatment options for patients with nonsmall cell lung cancer (NSCLC) who have been previously treated with immune checkpoint inhibitors (ICIs) and develop resistance.

As upfront treatment for NSCLC, the majority of patients are administered immunotherapy with chemotherapy or immunotherapy alone. Although these strategies are very beneficial to patients, disease progression is inevitable, and some patients become resistant to their frontline regimen.

Once a tumor grows too large or patients are ICI refractory, no effective therapies are available. The Lung-MAP nonmatched substudy S1800A was designed to address the need for treatment option after frontline ICI therapy in patients with NSCLC. The phase 2 clinical trial (NCT03971474) investigates the combination of ramucirumab (Cyramza) and pembrolizumab (Keytruda) vs standard of care.

0:08 | All patients now receive either a combination of immunotherapy and chemotherapy or immunotherapy alone as part of their frontline treatment for advanced nonsmall cell lung cancer. We're also starting to use immunotherapy in the treatment of earlier stage nonsmall cell lung cancer. So, most patients do get exposed to immune checkpoint inhibitors at some point during their therapy. And we know though there are great benefits that patients experience most will have tumor progression and develop some tumor resistance to immune checkpoint inhibitors.

0:47 | At this moment in time, we don't have the best therapies. We don't know the best therapies to provide patients once a tumor has grown on immune checkpoint inhibition and chemotherapy. So, this study is to evaluate what might be better therapies than our standard of care which generally include
