Group Intervention Description ALKS 4230 + pembrolizumab Pembrolizumab ALKS 4230 will be administered via SC injection once every 7 or 21 days at escalating doses or at the recommended phase 2 dose and schedule; pembrolizumab will be administered as an intravenous infusion given over 30 minutes; the dose level for pembrolizumab will be 200 mg per the approved label. In December 2020, an RP2D of 3 mg with an administration schedule of q7d was determined for SC ALKS 4230.

- Primary Outcome Measures
Name Time Method Incidence of Adverse Events (AEs), and identify the RP2D of ALKS 4230 in Part A From time of initiation of therapy until 30 days after last dose of study drug, assessed up to 24 months Includes AEs that are both serious and drug-related
Number of subjects experiencing AEs that are both serious and drug-related in Part B From time of initiation of therapy until 30 days after last dose of study drug, assessed up to 24 months Includes AEs that are both serious and drug-related
Clinical Activity of combination treatment with ALKS 4230 and pembrolizumab in each Part B tumor type. From time of therapy until the date of first documented tumor progression, assessed up to 24 months Overall Response rate (ORR) will be based on investigator review of radiographic and photographic images
- Secondary Outcome Measures
Name Time Method Duration of response in subjects with CR/iCR Time from the first documentation of complete response, measured approximately every 6 weeks, to the first documentation of objective tumor progression or death due to any cause (estimated up to 24 months) CR/iCR duration
Duration of response in subjects with PR/iPR Time from the first documentation of complete response, measured approximately every 6 weeks, to the first documentation of objective tumor progression or death due to any cause (estimated up to 24 months) PR/iPR duration
Overall survival for Part B Assessed up to 24 months Time from first dose of SC ALKS 4230 to the time of death
Proportion of subjects with objective evidence of Complete Response (CR)/immune CR (iCR) From time of initiation of therapy until the date of first documented tumor progression, assessed up to 24 months Overall response rate (ORR) will be based on investigator review of radiographic or photographic images
