Predicting the Success of the Late-Stage Cell-Based Cancer Immunotherapy Pipeline?

Adam
Feuerstein
(phama and biotech writer with TheStreet.com) has designed his own rule. 

For those who know or follow Adam, this will come as no surprise.  He is
neither short of rules nor opinion and is never shy in his vivid expression of
either.  But this rule is more than a simple expression of informed
opinion. It was born of hard data analysis and has yet to be broken.  In
Adam’s own words, this is how he and his colleague (Mark J. Ratain) came to the
rule they coined the Feuerstein-Ratain Rule:
[We] analyzed the outcomes of
59 phase III clinical trials of cancer drugs going back 10 years, stratified by
the market value of the companies four months prior to trial results being
announced. What we found was a remarkable difference between the market values of companies that had positive and negative
announcements
.  (the list of companies/products used can be found here
)
Specifically, the median market capitalization was approximately
80-fold greater for the companies with positive trials vs. companies with
negative trials. There were no positive trials among the 21 micro-cap companies
(companies with less than $300 million market capitalization) whereas 21 of 27
studies reported by the larger companies analyzed (greater than $1 billion
capitalization) were positive.
The
editorial, entitled “Oncology Micro-Cap Stocks: Caveat Emptor!”, can be
found in Journal of the National Cancer
Institute
 
(JNCI) at http://jnci.oxfordjournals.org/content/early/2011/09/26/jnci.djr375.full.
They identified
drugs that were undergoing evaluation in phase III trials or for regulatory approval
by the US FDA between January 2000 and January 2009. 
They calculated the
company value based on the market value of primary drug sponsor roughly
three months prior to the release of the data.  They concluded that
whether or not a company had pharma in place was not determinative of a drug’s
success but rather that partnerships or acquisitions by Big Pharma can play a
role in determining a drug’s success only in that these deals may increase the
market value of the primary drug sponsor.  That value was the
determinative factor.
This
is Adam’s summary of the analysis they did that led to the “Feuerstein-Ratain Rule”.  
Below
are the important snippets from the analysis behind the rule:
The "Feuerstein-Ratain
rule" is derived from an analysis of 59 phase III clinical trials of
cancer drugs conducted over the past 10 years. We actually had no say
whatsoever in the selection of cancer drugs used in the analysis. The list was
put together by health economist Allan Detsky of Toronto's Mount Sinai Hospital
and his co-authors as part of their paper published in the Journal of the National Cancer
Institute
 suggesting that
doctors entrusted with conducting late-stage cancer drug clinical trials are
using advanced knowledge of the results of these pivotal studies to engage in
illegal insider trading.
Ratain and I used the same list of 59 cancer drug clinical trials,
re-analyzed by market value of the drug sponsors, to debunk Detsky's
insider-trading theory. That's how the "Feuerstein-Ratain rule" came
about, and we published our conclusions in the JNCI alongside Detsky's paper.
To restate our findings:  No positive trials among the
21 micro-cap companies
(companies with less than $300 million market
capitalization) whereas 21 of 27 studies reported by the larger companies analyzed
(greater than $1 billion capitalization) were positive
There were 21 companies on the
list with market values of $300 million or less, with a 0% success rate in
phase III cancer drug clinical trials.
The list also contained 11 companies with market caps between
$300 million and $1 billion. The clinical trial success rate for this mid-tier
or second strata group was 18%. (Two positive clinical trials out of 11.)
Lastly, there were 21 of 27 studies reported by the larger
companies analyzed (greater than $1 billion capitalization) that were positive,
or a 78% success rate.
So
what interesting for us in cell therapy?
It
is interesting to note that the Feuerstein-Ratain Rule is
limited to oncology drugs and all the companies behind them were public. 
Adam has not – nor has anyone else to the best of my knowledge – looked at how
the rule may or may not translate outside of oncology.

Of
the cell therapy companies to have received market approval in US or EU in the
past 10 years, one was public (DNDN) and one was still private (TIG) and went
public shortly therafter in the same year. TiGenix was a private company and is
not in oncology so the analysis arguably does not apply.  However,
Dendreon’s Provenge is an oncology ‘drug’.  Dendreon had a market cap of
about $430M in the 4 months before its ph III data was announced and as such
would have fallen in the 18% likelihood of success category.  That sounds
about right.

I thought it might be interesting to do our own look at what the Rule might say about the pipeline of late-stage cell-based oncology trials.  Following
is a list of cell therapy companies currently in ph III or II/III for oncology:

* Trial not expected to complete until Q1
2014 so a lot could happen to the market cap in 2012/13.  It also could be
argued that this is not an oncology treatment as per original data set but a
treatment of the side  effects of the primary cancer treatment.
** Trial not expected to complete until Q1
2014 so a lot could happen to the market cap in 2012/13.
*** It could be argued that this is not an
oncology treatment as per original data set but 
a treatment of the side effects of the primary cancer treatment.
+ It could be argued this is not a cell
therapy though we would argue it is.  Others might argue that as a phase II/III
trial with only 60 patients this may not be powered to be a pivotal oncology trial.
^ Trial currently in “suspension” so this
date may be pushed out or trial terminated. It also could be argued that this
is not an oncology treatment as per original data set but a treatment of
the effects of the primary cancer treatment.  Others might argue that as a phase II/III trial with
only 70 patients this may not be powered to be a pivotal oncology trial.
Conclusion:  At the moment it looks like both NovaRx and ERYtech will go to their phase III data completion (June and October 2012 respectively) as private companies.  To qualify under the rule, Cell Medica would have to go public within the year and/or Kiadis would have to go public within the next 25 months. 

The only
companies with cell-based oncology products currently in late-stage trials to
which the Rule would apply are Molmed’s HSV-TK and Newlink Genetics’ HyperAcute
Pancreas.  

Assuming both MolMed and NewLink's trials progress as planned, we won’t know what
they look like under the rule until around Sept 2013 at which time we can assess their
market cap against the Rule.  At the moment, it’s looking pretty bleak for
both of them according to the Rule though at least the NLNK price has been
going in the right direction of late.  

Certainly one would expect trading
volume to dramatically increase on both these as their trial completion dates
near.  It remains to be seen how this will impact price but they would
have to  dramatically increase in market cap (double or triple) to succeed
as the Rule predicts. 

Naturally, this is just one way of looking at the world and, of course, this rule - as with all rules - is meant to be broken.

Can “Clinical Data Integration on the Cloud” be a reality?

Posted: March 11, 2012 at 3:56 pm

 

The story I am about to tell is almost 8 years old. I was managing software services delivery for a global pharmaceutical company from India. This was a very strategic account and the breadth of services covered diverse systems and geographies. It is very common that staff from the customer organization visit our delivery centers (offsite locations) to perform process audits, governance reviews and to meet people in their extended organizations.

During one such visit a senior executive noticed that two of my colleagues, sitting next to each other, supported their system (two different implementations of the same software) across two different geographies. They happened to have the name of the systems they support, pinned to a board at their desks. The executive wanted us to take a picture of the two cubicles and email to him. We were quite surprised at the request. Before moving on to speak to other people he asked a couple of questions and realized the guys were sharing each other’s experiences and leveraging the lessons learnt from one deployment for the other geography.  It turned out that this does not happen in their organization, in fact their internal teams hardly communicate as they are part of different business units and geographies

Coriander oil (cilantro) can be used to treat food poisoning and drug-resistant infections

Posted: March 11, 2012 at 3:55 pm

By Jonathan Benson

Food-borne illness outbreaks and the growing prevalence of antibiotic-resistant "superbugs" are two very serious societal problems for which researchers say they are actively looking for viable solutions. But one such solution found right in nature is coriander oil, which has been found to kill a number of different bacterial strains, as well as aid in digestion and treat the symptoms of food poisoning.

Dr. Fernanda Domingues and her colleagues from the University of Beira Interior in Portugal tested the effects of coriander oil, an essential oil extracted from the seeds of the coriander plant, also known as cilantro, on twelve different bacterial strains, including Escherichia coli (E. coli), Salmonella enterica, and methicillin-resistant Staphylococcus aureus (MRSA), the infamous hospital superbug.

Genetic manipulation boosts growth of brain cells linked to learning, enhances effects of antidepressants

Posted: March 10, 2012 at 12:23 pm

ScienceDaily (Mar. 8, 2012) UT Southwestern Medical Center investigators have identified a genetic manipulation that increases the development of neurons in the brain during aging and enhances the effect of antidepressant drugs.

The research finds that deleting the Nf1 gene in mice results in long-lasting improvements in neurogenesis, which in turn makes those in the test group more sensitive to the effects of antidepressants.

"The significant implication of this work is that enhancing neurogenesis sensitizes mice to antidepressants -- meaning they needed lower doses of the drugs to affect 'mood' -- and also appears to have anti-depressive and anti-anxiety effects of its own that continue over time," said Dr. Luis Parada, director of the Kent Waldrep Center for Basic Research on Nerve Growth and Regeneration and senior author of the study published in The Journal of Neuroscience.

Just as in people, mice produce new neurons throughout adulthood, although the rate declines with age and stress, said Dr. Parada, chairman of developmental biology at UT Southwestern. Studies have shown that learning, exercise, electroconvulsive therapy and some antidepressants can increase neurogenesis. The steps in the process are well known but the cellular mechanisms behind those steps are not.

"In neurogenesis, stem cells in the brain's hippocampus give rise to neuronal precursor cells that eventually become young neurons, which continue on to become full-fledged neurons that integrate into the brain's synapses," said Dr. Parada, an elected member of the National Academy of Sciences, its Institute of Medicine, and the American Academy of Arts and Sciences.

The researchers used a sophisticated process to delete the gene that codes for the Nf1 protein only in the brains of mice, while production in other tissues continued normally. After showing that mice lacking Nf1 protein in the brain had greater neurogenesis than controls, the researchers administered behavioral tests designed to mimic situations that would spark a subdued mood or anxiety, such as observing grooming behavior in response to a small splash of sugar water.

The researchers found that the test group mice formed more neurons over time compared to controls, and that young mice lacking the Nf1 protein required much lower amounts of anti-depressants to counteract the effects of stress. Behavioral differences between the groups persisted at three months, six months and nine months. "Older mice lacking the protein responded as if they had been taking antidepressants all their lives," said Dr. Parada.

"In summary, this work suggests that activating neural precursor cells could directly improve depression- and anxiety-like behaviors, and it provides a proof-of-principle regarding the feasibility of regulating behavior via direct manipulation of adult neurogenesis," Dr. Parada said.

Dr. Parada's laboratory has published a series of studies that link the Nf1 gene -- best known for mutations that cause tumors to grow around nerves -- to wide-ranging effects in several major tissues. For instance, in one study researchers identified ways that the body's immune system promotes the growth of tumors, and in another study, they described how loss of the Nf1 protein in the circulatory system leads to hypertension and congenital heart disease.

The current study's lead author is former graduate student Dr. Yun Li, now a postdoctoral researcher at the Massachusetts Institute of Technology. Other co-authors include Yanjiao Li, a research associate of developmental biology, Dr. Rene McKay, assistant professor of developmental biology, both of UT Southwestern, and Dr. Dieter Riethmacher of the University of Southampton in the United Kingdom.

New Industry Partnership to Strengthen Regenerative Medicine Industry in Canada

Posted: March 10, 2012 at 12:22 pm

TORONTO, ONTARIO--(Marketwire -03/09/12)- The newest player in the regenerative medicine (RM) field in Canada is taking a collaborative approach to commercializing stem cell and biomaterials products. The Centre for Commercialization of Regenerative Medicine (CCRM) has created an industry consortium that is working together to address real-life bottlenecks in their RM product pipelines.

CCRM's scientific leadership is recognized by the global RM community as being world-leading. According to Michael May, CEO of CCRM, partnering with industry completes the puzzle. "By working with industry, CCRM captures business expertise that informs product development and commercialization. We already had access to some of the best scientific minds in the field and now we have access to seasoned industry experts. This is key to our success and will accelerate product development."

The members of the industry consortium represent the key sectors of the RM industry: therapeutics, devices, reagents, and cells as tools. CCRM has built three core development platforms: reprogramming, cell manufacturing, and biomaterials and tissue mimetics. The intellectual property and infrastructure of CCRM's six research institution partners and support from 20 leading RM companies will enhance Canada's already strong leadership role in the RM field.

"CCRM is uniquely positioned to meet the needs of industry and academia," explains Greg Bonfiglio, Chair of CCRM's Board of Directors. "CCRM boasts scientific expertise and state-of-the-art resources in its development lab and this combination will benefit the regenerative medicine community that can capitalize on our ability to complete projects quickly and cost competitively."

The industry consortium members are as follows:

Study suggests breakthrough in organ transplants

Posted: March 10, 2012 at 3:15 am

Patients who are lucky enough to get a transplant for a failed organ usually face a lifetime on anti-rejection drugs, which are expensive, dangerous and not always effective.

But in the future, those drugs may not be needed. A new study suggests that patients receiving an organ that's less than a perfect match can be protected against rejection by a second transplant this time of the organ donor's imperfectly matched stem cells.

Though preliminary, the new study is being hailed as a potential game-changer in the field of transplantation, a mystifying development that could offer hope to hundreds of thousands of patients who await or have received donor kidneys and depend on a harsh regimen of daily anti-rejection pills.

GRAPHIC: Donor stem cells in transplants

The small pilot study, reported Wednesday in the journal Science Translational Medicine, describes a novel regimen that combined old-fashioned cancer treatments with 21st century cell therapy to induce five patients' immune systems to accept donor kidneys as their own despite significant incompatibility.

If the technique proves successful in a larger group of people, future transplant patients may need to take anti-rejection drugs only briefly, and some who rely on them now could discontinue them safely. The recipients of kidneys as well as other organs, including heart, lung, liver and pancreas, might also benefit from access to a wider pool of organs.

The strategy could offer hope, too, for patients receiving bone marrow transplants to treat blood cancers, speeding the process of finding a donor by allowing physicians to use stem cells that today would be rejected as incompatible.

"Few transplant developments in the past half century have been more enticing," wrote pioneer transplant surgeons James F. Markmann and Tatsuo Kawai of Massachusetts General Hospital, in a commentary accompanying the study. If borne out, they wrote, the findings "may potentially have an enormous, paradigm-shifting impact on solid-organ transplantation."

In an interview, Markmann said that the greatest benefit of techniques described in the new research would be to greatly improve the lives of transplant patients by freeing them of a lifetime reliance on anti-rejection drugs.

But it might also ease the shortage of transplantable organs somewhat by reducing the number lost to rejection, he said. According to the National Kidney Foundation, 4,573 U.S. patients died in 2008 awaiting a kidney transplant due to a donor shortage.
