Alkermes to Present Data on Nemvaleukin Alfa at the Society of Gynecologic Oncology 2022 Annual Meeting on Women's Cancer

–  New Ovarian Cancer Data From ARTISTRY-1 Clinical Trial to be Featured in Oral Plenary Session –

DUBLIN, March 1, 2022 /PRNewswire/ -- Alkermes plc (Nasdaq: ALKS) today announced plans to present data related to nemvaleukin alfa (nemvaleukin), the company's novel, investigational, engineered interleukin-2 (IL-2) variant immunotherapy, at the Society of Gynecologic Oncology (SGO) 2022 Annual Meeting on Women's Cancer, taking place March 18-21, 2022. New data in patients with platinum-resistant ovarian cancer from ARTISTRY-1, a phase 1/2 study evaluating the safety, tolerability and efficacy of intravenously administered (IV) nemvaleukin as a monotherapy and in combination with pembrolizumab (KEYTRUDA^®), will be presented in an oral plenary session. In addition, a trial-in-progress poster from the ongoing ARTISTRY-7 global phase 3 study will be presented. ARTISTRY-7 is evaluating the anti-tumor activity and safety of IV nemvaleukin in combination with pembrolizumab compared to investigator's choice chemotherapy, in patients with platinum-resistant epithelial ovarian, fallopian tube or primary peritoneal cancer.

Details of the presentations are as follows:

About Nemvaleukin Alfa ("nemvaleukin")  Nemvaleukin is an investigational, novel, engineered fusion protein comprised of modified interleukin-2 (IL-2) and the high affinity IL-2 alpha receptor chain, designed to preferentially expand tumor-killing immune cells while avoiding the activation of immunosuppressive cells by selectively binding to the intermediate-affinity IL-2 receptor complex. The selectivity of nemvaleukin is designed to leverage the proven anti-tumor effects of existing IL-2 therapy while mitigating certain limitations.

About the Nemvaleukin Clinical Development Program  
ARTISTRY is an Alkermes-sponsored clinical development program evaluating nemvaleukin as a potential immunotherapy for cancer. The ARTISTRY program is comprised of multiple clinical trials evaluating intravenous and subcutaneous dosing of nemvaleukin, both as a monotherapy and in combination with the anti-PD-1 therapy KEYTRUDA^® (pembrolizumab) in patients with advanced solid tumors. Ongoing trials in the ARTISTRY program include: ARTISTRY-1, ARTISTRY-2, ARTISTRY-3, ARTISTRY-6 and ARTISTRY-7.
