Merck / MSD announced that the U.S. Food and Drug Administration (FDA) has approved KEYTRUDA® (pembrolizumab), the company’s anti-PD-1 (programmed death receptor-1) therapy, for the treatment of adult and pediatric patients with refractory classical Hodgkin lymphoma (cHL), or who have relapsed after three or more prior lines of therapy. Under the FDA’s accelerated approval regulations, this indication is approved based on tumor response rate and durability of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in the confirmatory trials. In refractory or relapsed cHL, KEYTRUDA is approved for use in adult patients at a fixed dose of 200 mg and in pediatric patients at a dose of 2 mg/kg (up to a maximum of 200 mg). KEYTRUDA is administered intravenously every three weeks until disease progression or unacceptable toxicity, or up to 24 months in patients without disease progression.

“The results from KEYNOTE-087 showed that most patients with relapsed or refractory classical Hodgkin lymphoma responded to treatment with KEYTRUDA, and 22 percent experienced complete remission,” said Dr. Roger M. Perlmutter, president, Merck Research Laboratories. “Today’s approval – the first for KEYTRUDA in a hematologic malignancy – reinforces the hope that immunotherapy will prove useful in a wide variety of cancers.”

“For the patients with classical Hodgkin lymphoma who are not cured with existing treatments, there are limited options, and treating their disease becomes more challenging,” said Dr. Craig Moskowitz, clinical director, division of hematologic oncology, Memorial Sloan Kettering Cancer Center. “This approval is an important step forward in treating these patients, who are generally young and have a particularly poor prognosis, and gives us the opportunity to help patients in their fight against this devastating disease.”
