Stratification is basically an admission that what is classified clinically as a single disease is actually more than one disease at the molecular level. He serves as Director of NKT Therapeutics Inc. There is simply no excuse for taking an antibody into clinical trials without knowing what it binds. He served as a Director of Sportan United Industries Inc. since May 15, 2006. only three years in. Immunology is different. While there’s a lot to be said to phenotypic screening, where one may not really know the mechanism, it is truly baffling that an antibody would get developed without knowing the target.
This is graduate school stuff. 2016 Jan 16. Novartis owns all the ex-USA commercial rights. He has more than 15 years of experience in molecular biology research, having completed basic research fellowships at the Brain Tumor Research Institute and the Cardiovascular Research Institute and heading a National Institute of Health-funded laboratory at the University of California San Francisco. He has been an Executive Director of Medivation Inc. since December 17, 2004. Cancer cells have lost the ability to be regulated normally and therefore may express proteins only seen in embryogenesis that are not expressed in an adult.
Very sorry to hear about your situation. With PD-1 inhibitors estimated to bring in billions in sales and be the pillar for drug combination treatment for a variety of tumor types, having a best-in-class drug could be big for Medivation. Once you have a drug candidate, just stick to the data. Medivation got a steal when it acquired Talazoparib from BioMarin last week for $410 million upfront and up to $160 million in milestone payments.
He co-founded Medivation (NASDAQ: MDVN) in 2003. Due to Talazoparib’s superior mechanistic efficiency, it has several benefits over other PARP inhibitors such as bioavailability and half life.

Now, in addition to Xtandi, Medivation has a strong, low-risk drug pipeline and has developed into a full-fledged cancer-focused biotech company. What’s particularly rich about this whole thing is that one of the big assets that Medivation has, as mentioned above, is their PARP inhibitor. Its blockbuster prostate cancer drug Xtandi continues to blow away analyst estimates and is currently on pace to bring in ~$2 billion annually. An important distinction is that all the anti-PD1/PDL1 mAbs are in effector null frameworks (an IgG4 in humans) as these do NOT initiate ADCC function, and therefore the T-cells would not be destroyed by the patient’s own immune system. (Is there any way they could have hit PD-L1 by accident?). I don’t think it’s a common misconception that the FDA requires mechanism. Pharmacyclics only approved drug was Imbruvica which had revenue of ~$730M a year which was split with Johnson & Johnson. McCreight LJ1, Bailey CJ2, Pearson ER3. Granted, the, Growth At Reasonable Price, Momentum, Value, Biotech. If you need to stratify, then you’ve already lost. Frankly if I was in your shoes, I’d put that money on my kids education, or open a trust fund as downpayment on their first house. Thanks. All content is Derek’s own, and he does not in any way speak for his employer. Medivation Significantly Undervalued Compared to Peers. We’re still arguing about the mechanism for metformin, which is as close to a wonder drug for Type 2 diabetes as there is. Medivation also has a late-stage clinical drug in the PD-1 inhibitor Pidilizumab which it plans to initiate a Phase 3 clinical trial this year in a hematologic malignancy. This study makes a quantitative assessment of this effect. The antibodies generated in the mouse were screened against this cell line, then tested for efficacy in lymphoma models.
That would be NK cells and myeloid effectors. Stratification is basically an admission that your drug isn’t effective enough in the first place. The lead compound was in phase 2 when the receptor was identified and some time passed before Ghrelin was found. A January 11 presentation (in this SEC filing), though, does mention that PD-1 is apparently not the MOA, with “preliminary data” suggesting a different target. (AstraZeneca was said to be looking at an offer as well). Zytiga scored higher since it was awarded additional points for patient pain relief data. Or, more to the point, the response rates in PDL1+ vs PDL1 neg patients for Keytruda un lung cancer. Mechanism is often a basis for a lot of decisino in the clinic, you do not just pick up a bunch of patients and dose your drug. As I’ll discuss below, the ~40% drop in the last several months is largely based on rumors and assumptions which have turned out to be false. PD-1 is primarily expressed on T-cell and PDL-1 primarily on the tumors, and interaction between these proteins inhibits T-cell activation (this is why the tumors evolve to upregulate it). You need to have a best-in-class drug with a beneficial side effect profile and ease of use. Antibody binding is much better defined and understood. For any immunologist worth his salt this is nonsense. I contacted the head author of the ASCO scoring system who explained this was just an example for the article of how the scoring system would be calculated and not the final ASCO scores. There is no excuse in this day and age to not fully characterize the epitope to which a therapeutic antibody binds. Most of the comments in this thread appear to come from small molecule drug developers so it’s understandable how mechanism would be questionable. Medivation has made significant advancements with its drug pipeline, a blockbuster drug in Xtandi and strong acquisition potential.
