Gene therapeutics offer hope to many people with genetic and degenerative diseases. This includes those suffering from a muscle wasting disease. The underlying technology, however, is highly novel as only a few gene therapeutics are just now entering the market. This naturally raises many questions, some of which are answered below.
You can also learn more about gene therapy and muscle wasting diseases like the muscular dystrophies and cancer cachexia by visiting the links at the bottom of the page.
Is gene therapy safe?
AAV-based gene therapeutics have proven safe and well-tolerated in every clinical trial conducted to date. This is why the current resurgence in gene therapy is often described as the "golden age" for this technology.
No drug is absolutely safe, however, which is why particular care is taken when conducting clinical trials with emerging technologies like gene therapeutics. It's important to understand that despite the name, the adeno-associated viral vectors used today are entirely unrelated to the adenoviral vectors that produced tragic consequences in the '90s.
Is AAVogen conducting clinical trials with AVGN7 or AVGNF?
We are currently conducting safety/toxicology studies with AVGN7 and are planning similar studies for AVGNF. Detailed clinical trials for both drugs are of coursed planned and will hopefully start in the near future.
What are the prioritized indications for AVGN7?
Excellent question! Because AVGN7 antagonizes the fundamental biochemical events that are activated in many if not most muscle wasting disease states, it could potentially be used to treat a wide variety these disease indications.
Nevertheless, a focused development plan is key to quick market entry for any drug and to optimize its clinical impact. We have, therefore, parsed our development program to prioritize muscular dystrophy as the lead indication in the short-term and cancer cachexia in the long-term.
Targeting an orphan disease like muscular dystrophy ensures rapid market entry. It also provides the additional time needed to develop into a large market disease indication like cancer cachexia.
Why combinatorial therapy?
There is little doubt that replacement gene therapy works. Many studies, including our own with AVGNF, have proven the utility of adding a functioning gene into a cell, tissue or animal that harbors a genetic mutation. This is why big pharma has embraced the gene therapy approach especially for treating the muscular dystrophies.
However, and this is extremely important, no study has ever completely restored dystrophic muscle to normal. In fact, most studies with dystrophic animals used young animals that express a mild phenotype unlike that in human patients. The few studies using older animals or those that exacerbate the phenotype with exercise - a method that mimics injury-induced muscle degeneration in patients - report only partial restoration of muscle function.
All of this suggests that additional measures to boost muscle mass and strength are needed to overcome the accumulated damage from years of muscle degeneration. This is why we are developing a combinatorial approach, one that includes both AVGNF and AVGN7, to treat LGMD2i patients with advanced pathologies.
What are AAVogen's investment and development needs?
AAVogen is supported by grants and seed investments and is currently raising funds for Series-A financing. The latter will support our pre-clinical development program and the initiation of Phase I clinical trials.
Our financing goals are tranched to particular milestones and are leveraged by a record of highly successful grantsmanship, strong intellectual protection, equally strong legal representation and experienced management/leadership. We are also pursuing corporate partnerships and licensing to expand value propositions in all geographies.
