"The emergence of therapeutics targeting the PD-1 pathway has revolutionized the field of oncology, yet there remains significant opportunity to improve the clinical benefit of checkpoint inhibitors for the treatment of solid tumors. There is strong scientific rationale supporting the combination of PD-1 pathway inhibition with cytokine therapy such as ALKS 4230 to activate the body's own immune system to fight cancer, and the potential synergies of ALKS 4230 and pembrolizumab on anti-tumor activity may expand treatment options for patients in a variety of tumor settings," said
Evaluation of the safety and anti-tumor activity of ALKS 4230 in combination with pembrolizumab will be assessed in certain PD-1 approved tumor types in both refractory and treatment naïve patients, including non-small cell lung cancer (NSCLC), head and neck squamous cell carcinoma, gastric cancer, urothelial carcinoma and microsatellite instability-high cancers. Melanoma and renal cell carcinoma will also be evaluated in the cohort of treatment naïve patients. The combination of ALKS 4230 and pembrolizumab will also be assessed in certain PD-1 unapproved tumor types, including colorectal cancer, triple-negative breast cancer, ovarian carcinoma, soft tissue sarcomas, and patients with metastatic NSCLC whose tumors express low or undetectable PD-L1 (tumor proportion score <1%).
About the Phase 1 Study
The
Anti-tumor response and duration of response assessments in the dose-expansion and combination stages of the phase 1 study will be based on investigator-assessed, immune-related response (irRC) criteria and independent, central, blinded radiographic review per Response Evaluation Criteria in Solid Tumors (RECIST 1.1) criteria.
About ALKS 4230
ALKS 4230 is an engineered fusion protein designed to preferentially bind and signal through the intermediate affinity interleukin-2 (IL-2) receptor complex, thereby selectively activating and increasing the number of immunostimulatory tumor-killing immune cells while avoiding the expansion of immunosuppressive cells that interfere with anti-tumor response. The selectivity of ALKS 4230 is designed to leverage the proven anti-tumor effects while overcoming limitations of existing IL-2 therapy, which activates both immunosuppressive and tumor-killing immune cells.

Note Regarding Forward-Looking Statements
Certain statements set forth in this press release constitute "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995, as amended, including, but not limited to, statements concerning: the potential therapeutic and commercial value of ALKS 4230; and the clinical development plans for ALKS 4230, including the timing of expected presentation of initial data from the monotherapy dose-escalation stage of the phase 1 study and details of the planned monotherapy dose-expansion stage of the phase 1 study and the newly initiated combination therapy stage of the phase 1 study. You are cautioned that forward-looking statements are inherently uncertain. Although the company believes that such statements are based on reasonable assumptions within the bounds of its knowledge of its business and operations, the forward-looking statements are neither promises nor guarantees and are subject to a variety of risks and uncertainties, many of which are beyond the company's control, which could cause actual results to differ materially from those expressed or implied in the forward-looking statements. These risks and uncertainties include, among others, whether preclinical and early clinical results for ALKS 4230 will be predictive of future clinical study results; whether ALKS 4230 could be shown to be unsafe or ineffective; whether future clinical trials or future stages of ongoing clinical trials for ALKS 4230 will be initiated or completed on time or at all; changes in the cost, scope and duration of development activities for ALKS 4230; and those risks and uncertainties described under the heading "Risk Factors" in the company's Annual Report on Form 10-K for the year ended
