Pfizer's Mylotarg Recommended by FDA Advisory Committee

Read MoreHide Full Article

Pfizer Inc. (PFE - Free Report) announced that the FDA’s Oncologic Drug Advisory Committee (ODAC) voted in favor of Mylotarg for the treatment of patients with newly-diagnosed CD33-positive acute myeloid leukemia (AML).

The committee believes that the ALFA-0701 study investigating Mylotarg provides significant evidence supporting the risk benefit profile of Mylotarg in AML. A biologics license application (BLA) was submitted based on data from this study. A FDA decision is expected by Sep 2017.

The ALFA-0701 evaluated the safety and efficacy of Mylotarg, an antibody-drug conjugate (ADC), in addition to chemotherapy in AML. Mylotarg was administered to patients on the first, fourth and seventh day of the treatment.

Shares of Pfizer have risen 2.1% since the beginning of this year, underperforming the Zacks classified Large Cap Pharmaceuticals industry, which increased 10.4% in the same period.

We remind investors that Mylotarg was granted accelerated approval by the FDA in 2000 as a single agent for treating CD33-positive AML in patients who had experienced their first relapse and were 60 years or older. However, 10 years later, Pfizer voluntarily removed Mylotarg from the market as data from a post approval phase III study, SWOG S0106, showed no clinical benefit and rate of fatalities due to treatment-related toxicity was significantly higher.

The currently submitted BLA seeks approval for Mylotarg in two indications, for treating newly-diagnosed CD33-positive AML in combination with standard chemotherapy, and as monotherapy in patients aged over 60 who had first relapse and are not eligible for other cytotoxic chemotherapy. The BLA also includes data from five phase III studies including ALFA-0701, which contains 10 years of research data from 4,300 patients.

Per the press release, AML occurs in nearly 80% of acute leukemia patients and about 21,380 people are estimated to be affected by AML in the U.S. in 2017. Several companies are developing therapies for treating AML. The therapies include Seattle Genetics, Inc.’s SGN-CD33A and Intrexon Corporation’s CD33-specific CAR+ T therapy, in collaboration with ZIOPHARM Oncology, Inc. . However, despite recent developments there has been little progress in increasing the long-term survival rate in AML patients.
