Top 10 Oncology Drugs Available For Partnering (Part II)

This is the second part of an article I posted back in April. The final list includes only 9 candidates, as one of the candidates (Seattle Genetics’ SGN-75) was taken off the list after generating fairly disappointing results at ASCO. Enjoy.

Micromet

Micromet (MITI), who is developing antibodies for cancer, definitely has a potential game changer in its hands. The company’s lead agent, blinatumomab (Bmab), belongs to a new class of antibodies called BiTE (Bispecific T cell Engagers). These antibodies can harness the patient’s immune system to attack tumors by redirecting T cells (the most potent immune cells in the body) against cancer cells. BiTE antibodies achieve this by simultaneously binding a cancer cell on one side and an immune cell on the other. This unleashes a potent anti-tumor immune response. Continue reading →

Putting A Price Tag On Synta’s Lead Agent

2011 is shaping up as a transformational year for Synta (SNTA), who is making progress on multiple fronts with its lead agent ganetespib (formerly known as STA-9090). Ganetespib is an Hsp90 inhibitor, a protein with a well recognized role in cancer. The concept of inhibiting Hsp90 to fight cancer goes back two decades, but all attempts have been beset by failures so far. As Synta’s ganetespib appears to be the first active and safe Hsp90 inhibitor, it is poised to make a big dent in the multibillion dollar oncology market. I discussed the history of Hsp90 inhibitors and Synta’s unique positioning in a previous write up.)

Synta’s lead program gains momentum

In the pharmaceutical industry, it is very common to see multiple drugs in development that go after the same target. Usually, there is a direct correlation between the recognition a target has and the number of competing agents. This is the case with “hot targets” such as PI3K,RAF and mTOR, which are pursued by many pharma and biotech companies.

 

In most cases (especially with targeted therapies), the different compounds are being developed in parallel, and there is no way of identifying a clear winner. This can persist even after approval. For instance, both BMS Pfizer and Novartis (NVS) have an mTOR inhibitor on the market for the treatment of renal cancer. It is clear both drugs are active but each compound was approved based on a different trial in a different patient population, so neither can claim superiority.
