A Phase I Dose Escalation and Dose Expansion Study to Investigate the Pharmacokinetics and Safety of Subcutaneous Durvalumab
A Phase I, Multicentre, Dose Escalation and Dose Expansion Study to Investigate the Pharmacokinetics and Safety of Subcutaneous Durvalumab in Adult Participants With Solid Tumours
AstraZeneca
40 participants
Mar 31, 2026
INTERVENTIONAL
Conditions
Summary
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).
