- ARTISTRY-1 Data Showed Anti-Tumor Activity of Nemvaleukin, as a Monotherapy and in Combination with Pembrolizumab, in Multiple Tumor Types -
- Company to Host Investor Webcast on June 6 at 8:00 a.m. ET -
DUBLIN, June 1, 2022 /PRNewswire/ -- Alkermes plc /zigman2/quotes/205084517/composite ALKS -0.70% today announced plans to present data from the ARTISTRY-1 clinical trial for nemvaleukin alfa (nemvaleukin), the company's novel, investigational, engineered interleukin-2 (IL-2) variant immunotherapy. The data will be presented in an oral presentation at the 2022 American Society of Clinical Oncology (ASCO) Annual Meeting, taking place June 3-7, 2022 in Chicago and virtually, and in an investor webcast hosted by the company on June 6, 2022.
The presentations will include efficacy and safety data from ARTISTRY-1, a phase 1/2 study evaluating the safety, tolerability and efficacy of nemvaleukin administered intravenously as a monotherapy and in combination with pembrolizumab (KEYTRUDA [(R)] ). In this study, nemvaleukin demonstrated anti-tumor activity with durable responses as monotherapy in checkpoint inhibitor (CPI)-experienced melanoma and renal cell carcinoma (RCC) patients and as combination therapy in pretreated patients across a range of difficult-to-treat tumors, including in tumor types where CPIs have had limited clinical benefit, and in CPI-experienced patients. Treatment-related adverse events (AEs) were mostly transient and manageable.
"The results of ARTISTRY-1 demonstrate that selectively targeting the IL-2 pathway may deliver significant clinical benefit in multiple tumor types while mitigating the hallmark toxicities associated with high-dose recombinant-IL-2," said Ulka N. Vaishampayan, M.D., Professor, Internal Medicine, Division of Hematology/Oncology, University of Michigan. "These data specifically highlight the potential clinical utility of nemvaleukin as a monotherapy and in combination with pembrolizumab in heavily pretreated patients across multiple tumor types, including in mucosal melanoma and platinum-resistant ovarian cancer."
"ARTISTRY-1 provided important data that has revealed nemvaleukin's pharmacokinetic and pharmacodynamic profile, exhibited similar monotherapy anti-tumor activity as seen with high-dose IL-2, demonstrated anti-tumor activity in combination with a CPI, and established a differentiated safety and tolerability profile," said Craig Hopkinson, M.D., Chief Medical Officer and Executive Vice President of Research & Development at Alkermes. "As we focus on enrolling our potential registrational studies, ARTISTRY-6 in mucosal melanoma and ARTISTRY-7 in platinum-resistant ovarian cancer, these data from ARTISTRY-1 further reinforce our understanding of nemvaleukin's profile and our belief in its clinical potential."
Data highlights from the ASCO oral presentation and the company's investor presentation include the following (all data are as of the Oct. 29, 2021 ASCO data cutoff date, unless otherwise noted):
ARTISTRY-1, Nemvaleukin IV Monotherapy
The ARTISTRY-1 monotherapy cohorts included heavily pretreated, CPI-experienced patients with advanced melanoma or RCC.
Melanoma monotherapy cohort (46 evaluable patients):
RCC monotherapy cohort (22 evaluable patients):
ARTISTRY-1, Nemvaleukin IV in Combination With Pembrolizumab The ARTISTRY-1 combination cohorts included patients with PD-1/L1 unapproved tumor types; patients with PD-1/L1 approved tumor types (PD-1/L1 pretreated and PD-1/L1 treatment naive) as well as tumor-specific cohorts and a cohort for patients who rolled over into a combination cohort from a monotherapy cohort.
Among the 137 total evaluable patients, four complete responses (CRs) and 18 PRs were observed, SD was observed in 60 patients, and overall median DOR was 23 weeks.
In the PD-1/L1 unapproved cohort (36 evaluable patients):
In the PD-1/L1 approved cohorts (total 43 evaluable patients):
Treatment-related adverse events (TRAEs) across the ARTISTRY-1 study were consistent with those previously reported for the IV nemvaleukin monotherapy and combination therapy-treated populations from the trial. Pyrexia, chills and neutropenia/decreased neutrophil count were the most commonly reported TRAEs. Across the ARTISTRY-1 study, nemvaleukin in combination with pembrolizumab demonstrated no additive toxicity compared to pembrolizumab alone and no event of capillary leak syndrome was reported.
"Immunotherapies have revolutionized cancer treatment, but significant unmet need remains, as many patients are not eligible or do not respond to certain immunotherapies such as checkpoint inhibitors. Broadening the benefits of immunotherapy to a wider range of patients is an important goal for the treatment community and cancer researchers," said Jill O'Donnell-Tormey, Ph.D., Chief Executive Officer and Director of Scientific Affairs, Cancer Research Institute. "These data from ARTISTRY-1, particularly in patients who are not eligible for current immunotherapies such as a PD-1/L1 inhibitor or who have progressed following treatment with immunotherapies, suggest that nemvaleukin may provide clinical benefit in this patient population. These data support further evaluation of nemvaleukin in future studies."
Trial-in-progress posters from the ongoing ARTISTRY-3 trial and the potential registration-enabling ARTISTRY-6 and ARTISTRY-7 trials will also be presented at the ASCO meeting.

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.
