PF-06730512

Pfizer is culling a handful of clinical programs, including trials in cancer and dermatology, it announced Tuesday. The cuts include two Phase II programs, one a topical PDE4 inhibitor (PF-07038124) for psoriasis and atopic dermatitis, and another (PF-06730512) in focal segmental glomerulosclerosis, a condition that can lead to kidney failure. It has also decided to squash three Phase I programs, two of which targeted non-small cell lung cancer and another in development against solid tumors.

EXTON, PA., Sept. 21, 2022 /PRNewswire/ -- Focal segmental glomerulosclerosis (FSGS) is one of the leading causes of nephrotic syndrome across the world and is considered the most common glomerular cause of end-stage renal disease (ESRD).1 Spherix has been tracking the evolution of the FSGS market since 2018 to keep a pulse on how nephrologists are treating patients and the perceived potential for products as they make their way through development. Over the past few months, Spherix has released two reports revealing insights from both US-based and EU5-based nephrologists as a part of its Market Dynamix™: Focal Segmental Glomerulosclerosis (FSGS) research services. Insights were gathered from qualitative and quantitative research conducted with 100 nephrologists across the United States and more than 250 nephrologists from France, Germany, Italy, Spain, and the UK. These services provide insights into perceptions of unmet needs, gaps in care, and evolving treatment paradigms. Of note, Spherix experts found that while most FSGS patients are still confirmed via kidney biopsies, nephrologists are becoming increasingly likely to use genetic testing for diagnosis. As understanding of genetic causes of disease advances (including the role of APOL-1), nephrologists are optimistic for more targeted and effective therapies. Other findings of the US- and EU5-based research reveal that nephrologists across both geographies strongly agree that reducing proteinuria is an important treatment goal for their FSGS patients, as they believe proteinuria is a key contributor to FSGS progression. However, key regional differences emerge when nephrologists consider which proteinuria levels may trigger use of steroids, with some physicians much more aggressive and others more conservative. A major shift seen over the past year is the increasing use of SGLT2 inhibitors (including AstraZeneca's Farxiga/Forxiga, Boehringer Ingelheim/Lilly's Jardiance, and Janssen's Invokana) in glomerular disease patients. Nephrologists in the EU5 and the US are using these products more often in their FSGS and IgA nephropathy patients in particular, especially those with lingering proteinuria after initial ACE inhibitor and/or ARB treatment. In fact, reported use of SGLT2 inhibitors in primary FSGS patients more than doubled year-over-year in both regions captured in these studies, with expectations for continued growth. A growing number of nephrologists also indicate they will start patients on an ACEi/ARB alongside an SGLT2 inhibitor as they embrace this new mechanism of action. Despite the addition of SGLT2 inhibitors to the armamentarium, nephrologists across the EU5 and the US continue to rate FSGS patients overall as highly challenging to manage and believe there is an extremely high unmet need for new treatment options. To gauge pipeline product potential, Spherix assessed awareness, familiarity, desire to have approved, likelihood to prescribe, and estimated patient candidacy for the following assets: Abatacept (BMS) Atrasentan (Chinook) Bardoxolone methyl (Reata) Blesumab, ASKP1240 (Astellas/Kyowa Kirin) DMX-200 (Dimerix) GFB-887 (Goldfinch Bio) PF-06730512 (Pfizer) Sparsentan (Travere, commercialized by Vifor in the EU) VAR 200 (ZyVersa) VX-147 (Vertex) Spherix has in-depth expertise across the glomerular disease market (including FSGS, IgA nephropathy, Alport syndrome, C3G, membranous nephropathy, and more).
