A Study to Investigate the Pharmacokinetics and Safety of Subcutaneous Rilvegostomig in Adult Participants With Advanced Solid Tumors Previously Treated With Standard of Care Therapy
- Conditions
- Advanced Solid Tumors
- Interventions
- Drug: IV RilvegostomigDrug: SC rilvegostomig + rHuDrug: Recombinant Human Hyaluronidase (rHu)Drug: SC Rilvegostomig
- Registration Number
- NCT07161414
- Lead Sponsor
- AstraZeneca
- Brief Summary
The purpose of this study is to determine the subcutaneous (SC) dose that gives rilvegostomig exposure comparable to the intravenous (IV) exposure, and to evaluate the pharmacokinetics (PK) and safety of SC rilvegostomig in adult participants with advanced solid tumors previously treated with standard of care therapy for whom immunooncology (IO) monotherapy would be deemed appropriate by the investigator.
- Detailed Description
This is a Phase I, open-label, multicenter, multi-part, dose finding and dose confirmation study to evaluate the PK and safety of SC rilvegostomig.
The study includes 2 parts: Part 1 (Dose Finding) and Part 2 (Dose Confirmation).
Part 1 will determine a SC rilvegostomig dose co-administered with rHu that yields drug exposure comparable with IV rilvegostomig. It will include 2 planned dose levels (DL1 in Cohort A and DL2 in Cohort B). Additional dose levels will be added, if needed.
Part 2 will be initiated once a dose has been identified based on Part 1. This part will evaluate the bioavailability, safety, and tolerability of SC rilvegostomig + rHu.

- Primary Outcome Measures
Name Time Method Area under the Concentration-time Curve During One Dosing Interval (AUCtau) From Day 1 up to end of Cycle 2 in Part 1 and end of Cycle 1 in Part 2 (each cycle will be of 3 weeks) Bioavailability based on AUCtau at first SC dose will be determined.
- Secondary Outcome Measures
Name Time Method Number of participants with adverse events (AEs) From Day 1 up to 90 days post last dose (Up to approximately 29 months) To assess safety and tolerability of SC rilvegostomig. Safety and tolerability will be evaluated in terms of AEs (graded by CTCAE version 5.0), clinical laboratory assessments, vital signs, physical examinations, and ECOG performance status.
