简要总结
The purpose of the study is to determine a subcutaneous (SC: under the skin) durvalumab + recombinant human hyaluronidase (rHu) dose that yields systemic drug exposure similar to intravenous (IV: into the veins) durvalumab administration and to evaluate the pharmacokinetics and safety of SC durvalumab + rHu injection in participants with different types of solid tumours (cancers).
详细描述
This is a Phase I, multicentre study that will consist of 2 parts -
- Part 1: Dose Escalation
- Part 2: Dose Expansion
Part 1 may include participants with solid tumours - non-small cell lung cancer (NSCLC), hepatocellular carcinoma (HCC) or limited-stage small cell lung cancer (LS-SCLC). It will further consist of 2 planned dose levels of SC durvalumab - Dose level 1 (DL1) and Dose level 2 (DL2).
Part 2 will include participants with unresectable HCC. It will be initiated once a dose has been identified based on Part 1.
