Study Summary

Phase 1b: To evaluate the safety and tolerability of multiple ascending doses of efavaleukin alfa in subjects with steroid refractory chronic graft versus host disease (cGVHD). Phase 2: To evaluate the efficacy of efavaleukin alfa in subjects with steroid refractory cGVHD as measured by overall response rate (ORR) at 16 weeks according to the 2014 cGVHD NIH Consensus Criteria. Due to early termination, the Phase 2 portion of this study was not conducted.

Primary Outcome

A DLT was defined as a: * Non-hematological toxicity ≥grade-4(per common terminology criteria for adverse events \[CTCAE\] v4.03) related to efavaleukin alfa. Non-hematological lab abnormalities without clinical significance weren't considered DLTs. * Hematological toxicity ≥grade 4 related to efavaleukin alfa defined as decreases in peripheral counts (absolute neutrophil count or platelets) persisting longer than 72 hrs, as measured by 2 separate results, that were not related to malignant dis
