Oxigene’s positive PhII ovarian cancer data faces analyst’s skepticism

An analysis from Adam Feuerstein at TheStreetis skeptic on Oxigene’s positive Phase II ovarian cancer data (External Source FierceBiotech, OXiGENE, NOV 12, 2014, View Source;utm_source=internal [SID:1234500966]). A decision on using Avastin for ovarian cancer is looming, but hasn’t arrived yet, complicating any analysis of a combination drug study like this. Avastin, by the way, achieved a solid PFS but not a statistically significant overall survival benefit for ovarian cancer patients, which may not prevent its approval. If Avastin plus chemo becomes the standard of care in this area, then Oxigene will face some big challenges in designing a Phase III trial, notes Feuerstein. If the biotech decides to run a non-inferiority study, it will need a big and expensive patient population to examine. If it tries to beat Avastin/chemo, it faces a very tall order. And if Avastin is rejected, that makes Oxigene’s task even more difficult. Perhaps, suggests Feuerstein, the company should go a different route and try a combination with Votrient.
