SYDNEY, AUSTRALIA and SAN DIEGO, CA--(Marketwire -02/06/12)- Benitec Biopharma (ASX: BLT.AX - News) and Medistem (Pinksheets: MEDS.PK - News) announced today the successful treatment of rheumatoid arthritis in preclinical models using Benitec Biopharma's patented gene silencing technology applied to stem cell-derived immune system cells called dendritic cells. The studies, which were led by Dr. Wei-Ping Min of the University of Western Ontario, were published in the "Journal of Translational Medicine" on the 31st January 2012(1). Benitec Biopharma's CEO Dr Peter French and Medistem's scientist Dr Rosalia De Nochea Champion were co-authors on the paper.

"In 2003, Dr Wei-Ping Min's group, together with Medistem's CEO Dr Thomas Ichim, were the first to apply the technology of RNA Interference to the immune system, by silencing the autoimmune disease-associated gene IL-12p35(2)," said Dr. Peter French. "In the current paper, Dr. Min expanded these studies to a disease-relevant model, and using stem cell-derived dendritic cells was capable of developing promising preclinical data relevant to rheumatoid arthritis."

By specifically "silencing" various genes, Benitec Biopharma's ddRNAi technology is capable of modulating stem cells outside of the body, in order to endow them with new desired therapeutic activities. The first clinical study which combined stem cell therapy with Benitec Biopharma's ddRNAi technology was in a trial of AIDS-related lymphoma patients, the results of which were published in 2010 and showed the safety and feasibility of the approach(3).

In the current paper, ddRNAi was used to generate dendritic cells that acted as a "tolerogenic vaccine," which specifically blocked the pathological immune response in rheumatoid arthritis, without blocking healthy immune responses. It is contemplated that by blocking pathological immunity, ddRNAi-modified stem cell-based therapies, such as those being developed by Medistem, could provide novel treatment and curative approaches to tissue that has been damaged. In the case of rheumatoid arthritis the tissue would be cartilage and synovium.

"Medistem is the first company to take a stem cell from discovery to clinical trials in the short span of four years," said Dr. Weiping Min. "This is a unique example of merging basic research, as performed in my laboratory with the translational expertise of Dr. Ichim's company."

Medistem has previously published work in the area of rheumatoid arthritis, however the company's main efforts are currently focused on heart failure, for which it has started the RECOVER-ERC 60 patient double blind, dose escalating, placebo controlled trial using its Endometrial Regenerative Cell (ERC) universal donor stem cell. The company also has a critical limb ischemia trial recently approved by the FDA.

"In our opinion the Benitec Biopharma technology platform is the only means of inducing the stable expression of gene silencing in a stem cell," said Dr. Ichim, CEO of Medistem. "Given that Benitec Biopharma has pioneered ddRNAi for human therapy, and has been involved in applying it to stem cell manipulation, we are eager to continue our collaborations and finding means of leveraging the unique properties of the ERCs with the transformational technology of ddRNAi to develop novel cell therapies for a range of chronic life-threatening human diseases."

"Benitec Biopharma and Medistem are in discussions as to how to advance this work both in rheumatoid arthritis and in a range of other disease states that would lend themselves to such a novel combination therapy," Dr. French added.

About Benitec Biopharma

Benitec Biopharma Ltd is developing novel treatments for chronic and life-threatening conditions based on targeted gene-silencing activity using a transformational technology: DNA-directed RNA interference (ddRNAi) -- sometimes called expressed RNAi. The technology's potential to address unmet medical needs and to cure disease results from its demonstrated ability to permanently silence genes which cause the condition. Importantly, this technology's target gene and related gene pathways will rarely have presented as a therapeutic avenue for research for the traditional small molecule agents, currently accounting for the majority of today's pharmaceutical products.

Benitec now either owns or exclusively licenses from CSIRO more than 40 granted or allowed patents in the field of RNA interference for human therapeutic applications. Patents have been granted in key territories such as the USA, the UK, Japan, Europe, Canada and Australia. In addition, Benitec has almost 50 patent applications pending for which it is the owner or exclusive licensee from CSIRO, and has further intellectual property under development as a result of its pipeline program.

Founded in 1997 and trading publicly since 2001, Benitec Biopharma is listed on the Australian Securities Exchange (ASX) under the symbol "BLT." Benitec aims to deliver a range of novel ddRNAi-based therapeutics to the clinic in partnership with the pharmaceutical industry. In addition to its focused R&D strategy in infectious diseases, cancer and chronic cancer-associated pain, Benitec Biopharma is pursuing programs with licensees.

Benitec Biopharma and Medistem Technologies Successfully Combined in Preclinical Stem Cell Therapy for Rheumatoid ...

McMaster University is on its way to moving stem cell research “from the bench to the bedside” thanks to a $30 million boost from a local family.

The Marta and Owen Boris Foundation made the large donation to establish a human stem cell therapy centre and a unique clinic for patients with complex health conditions.

Owen, the founder of Mountain Cablevision, was in talks with McMaster about investing in their work before he died last April. His children and wife contacted the university a month later and carried out his vision, firming up their commitment last November.

The Boris Family Centre in Human Stem Cell Therapies will be developed as part of the McMaster Stem Cell and Cancer Research Institute using $24 million of the funds.

“It’s getting over that chasm from the bench to the bedside that this (donation) is going to allow us to do,” the institute’s scientific director Dr. Mick Bhatia said.

The centre will give scientists the resources to focus on converting McMaster’s breakthroughs — such as the ability to make blood or types of neural cells with stem cells — into clinical applications through investigative trials, Bhatia said.

“In the absence of this donation, I think we would not be in the position to move our discoveries forward,” he said. “This is a huge leg-up. I’m hoping what it’s really going to do is have a ripple effect to change the way McMaster views translating basic science.”

They plan on developing human stem cell therapies targeting leukemia and possibly neural diseases such as Alzheimer’s and Parkinson’s, said Dr. John Kelton, dean and vice-president of the faculty of health sciences.

The remaining $6 million will go toward building a clinic in partnership with Hamilton Health Sciences (HHS) where patients with complex health issues can see specialists and undergo tests in one visit.

This was a result of his parents’ frustrating experiences in recent years with co-ordinating specialists and getting diagnostic testing done in Canada, said Owen’s son, Les Boris.

They ended up going to Mayo Clinic in Rochester, Minn., where they had a case manager who co-ordinated their appointments with specialists and made sure testing was done in-house, he said. “They like the idea of a one-stop shop … (My father) said: ‘This is the kind of model we need here in this country.’”

Kelton said the medical clinic, which will be built in the university’s medical centre, will look for rapid turnaround times and avoid duplications of lab tests. McMaster and HHS will also evaluate the clinic’s success and keep an electronic medical record that patients could access, he said.

Kelton and Owen met three years ago and had their last meeting about the projects three days before the philanthropist died.

Owen had worked on the Avro Arrow and was frustrated with Canada’s lost opportunity of making jet planes for the world, Kelton said.

“He said, ‘Tell me about some opportunities (that) – if we invested in it – could make Hamilton and McMaster world-class. What are some of the areas like an Avro Arrow?’”

The funds for the human stem cell therapy centre will go toward hiring a research chair in blood stem cells and a research chair in neural stems cells, setting up several fellowships and technician positions, and building the facility.

Bhatia says they hope to bring in new scientists and fellows by the early summer.

The Boris family previously donated $6 million to addiction research at St. Joseph’s Healthcare for its new mental health hospital being built on the Mountain and another $5 million for the da Vinci SI Surgical Robotic System.

“We’re very appreciative that we’re in a position to be doing something for the community,” Les said. “And it was the community that put us in the position to do this.
