Pfizer And GSK To Initiate Study Of Novel Combination Therapy In Patients With Melanoma
Phase I/II Study combines GSK’s trametinib and Pfizer’s palbociclib
Pfizer Inc. announced today that it has entered into an agreement with GSK to explore the anti-cancer efficacy and the safety of GSK’s trametinib (GSK1120212) combined with Pfizer’s palbociclib (PD-0332991) in a Phase I/II study (Study 200344) in patients with advanced/metastatic melanoma.
Study 200344 is a dose-escalation, open-label study designed to determine the recommended combination regimen (RCR) for trametinib plus palbociclib in patients with melanoma. The study will also evaluate the effect of the combination on tumor biomarkers, safety and anti-cancer activity in patients with BRAFV600 wild type melanoma, including those with NRAS mutations.
“Pfizer Oncology is committed to maximizing the value of our portfolio for patients through the study of novel combinations. This includes combining our own cancer medicines with each other, as well as with those of other companies where there is strong scientific rationale,” said Garry Nicholson, president and general manager, Pfizer Oncology Business Unit. “Emerging data suggest the potential for trametinib and palbociclib to work together to treat melanoma. We look forward to collaborating with GSK to explore this potential and evaluate the clinical activity of this combination in melanoma.”
The two companies will collaborate on the study, which GSK will conduct. Financial terms of the agreement were not disclosed.
Trametinib, a reversible inhibitor of MEK1 and MEK2, is approved by the U.S. Food and Drug Administration (FDA) under the name Mekinist® for the treatment of adult patients with unresectable or metastatic melanoma with BRAF V600E or V600K mutation as detected by an FDA-approved test. Mekinist is not indicated for the treatment of patients who have received a prior BRAF inhibitor therapy.
Palbociclib is an investigational oral and selective inhibitor of cyclin dependent kinases (CDK) 4 and 6. In April 2013, palbociclib received Breakthrough Therapy designation by the FDA for the potential treatment of patients with breast cancer. Palbociclib is not approved for any indication in any markets.
