Pfizer's Drug Combo Betters Survival in Kidney Cancer Study

Read MoreHide Full Article

Pfizer, Inc. (PFE - Free Report) announced that a combination of its cancer drugs, Bavencio and Inlyta, significantly improved progression-free-survival (“PFS”) in a pivotal late-stage study. The phase III JAVELIN Renal 101 study evaluated the Bavencio/Inlyta combination against Pfizer’s older kidney cancer drug Sutent for first-line treatment of advanced renal cell carcinoma, the most common form of kidney cancer.

Top-line results from the study showed that treatment with the Bavencio/Inlyta combination led to statistically significant improvement in progression-free survival (PFS) in patients whose tumors had PD-L1 expression greater than 1% as well as in the entire study population regardless of PD-L1 tumor expression. An independent Data Monitoring Committee confirmed the results as part of a planned interim analysis.

The primary endpoint of the study was to show the superiority of the Bavencio/Inlyta over Sutent monotherapy in prolonging PFS or overall survival (OS) in patients with PD-L1+ tumors.

Pfizer mentioned that the study will continue as planned to analyze the other primary endpoint of OS. Based on the interim results for PFS, Pfizer and Merck KGaA (MKGAF - Free Report) will file regulatory applications in the United States. Pfizer is developing Bavencio with its Germany-based partner Merck KGaA.

The study combines an anti-PD-L1 antibody, Bavencio with a tyrosine kinase inhibitor (TKI), Inlyta, which, if approved, will represent a new cancer treatment approach for advanced RCC. Detailed data from the study will be presented at a future medical conference.

Pfizer’s stock has risen 16.8% this year so far, outperforming the industry’s rally of 4.7%.

 

 

Bavencio is already approved in metastatic Merkel cell carcinoma, (mMCC), a rare and aggressive skin cancer in the United States, Europe and Japan. It has also received accelerated approval for second-line treatment of locally advanced or metastatic urothelial carcinoma (advanced bladder cancer) in the United States. Inlyta is approved as a monotherapy for the second-line treatment of advanced RCC.

Bavencio is being considered a key long-term growth driver for Pfizer. In January, Pfizer had mentioned that within its immuno-oncology portfolio, focus remains mainly on drug combinations of Bavencio with a variety of Pfizer-targeted agents. The positive data from the latest study supports this belief.

Currently, avelumab is being developed for more than 15 types of tumors including breast, gastric/gastro-esophageal junction, head and neck, Hodgkin’s lymphoma, melanoma, mesothelioma, Merkel cell carcinoma, non-small cell lung cancer, ovarian and urothelial carcinoma. These studies are part of the JAVELIN development program. 

Other PD-L1 inhibitors on the market are Merck’s (MRK - Free Report) Keytruda, Bristol Myers’ Opdivo and AstraZeneca’s (AZN - Free Report) Imfinzi.
