177Lu-anti-PD-L1 sdAb in Metastatic Solid Tumors
Trial Parameters
Brief Summary
This is a Phase 0/1, First-in-Human (FIH), study to evaluate safety, tolerability, biodistribution, radiation dosimetry and preliminary anti-tumour activities of 177Lu-RAD204 in participants with selected solid tumours, to identify the MTDs/ recommended doses of 177Lu-RAD204 for future exploration. The study will consist of a Pre-screening Period (if applicable for PD-L1 testing), a Screening Period of up to 4 weeks, followed by a Phase 0 (Imaging) Period for imaging and dosimetry to 177Lu-RAD204im and a Phase I (Treatment) Period for 177Lu-RAD204tr dose escalation.
Eligibility Criteria
Inclusion Criteria: 1. Willing and able to provide informed consent prior to start of any study procedures and assessments and must be willing to comply with all study procedures. 2. Adult participants ≥ 18 years of age. 3. Participants with a documented history of histopathologically confirmed relapsed/refractory locally advanced, inoperable or metastatic NSCLC, SCLC, TNBC, cutaneous melanoma, HNSCC, endometrial cancer or any cancer that is known to be MMR deficient or MSI high with documented disease progression during or after their most recent line of anticancer therapy. Participants must be refractory to or have refused standard of care therapy (including PD-1/PD-L1 inhibitors) or have refused or have no standard of care therapy available that is likely to provide clinical benefit. 4. Participants with PD-L1 positive NSCLC, SCLC, TNBC, cutaneous melanoma, HNSCC, endometrial cancer or any cancer that is known to be MMR deficient or MSI high: * If the participant tumour's PD-L1 expr
