Summary

This trial is testing a new drug, SRK-181, to see if it is safe and effective in treating solid tumors. The study will test different doses of the drug alone and in combination with another anti-cancer drug. The trial is divided into 3 parts, with a long-term extension phase.

Who is the study for?
This trial is for adults with advanced solid tumors who haven't responded to anti-PD-(L)1 therapy, have measurable disease, and no suitable standard care options. They must be in good physical condition with a life expectancy of at least 3 months. Women must test negative for pregnancy and agree to birth control measures.
What is being tested?
The DRAGON study tests SRK-181 alone or combined with anti-PD-(L)1 therapy in patients whose cancer hasn't improved after previous treatments. It's an early-phase trial assessing safety, dosage, body response, and effectiveness across multiple patient groups.
What are the potential side effects?
Potential side effects include reactions related to the immune system such as inflammation in various organs due to the drug's mechanism of enhancing immune activity against cancer cells. Specific side effects will be monitored throughout the trial.

Trial Design

4Treatment groups
Experimental Treatment
Group I: Part B: Dose ExpansionExperimental Treatment2 Interventions
In Part B, parallel cohorts of patients with Non-Small Cell Lung Cancer (NSCLC), Urothelial Carcinoma (UC), Cutaneous Melanoma (MEL), Clear Cell Renal Cell Carcinoma (ccRCC), Head and Neck Squamous Cell Carcinoma (HNSCC), or other advanced or metastatic solid tumor type that is not NSCLC, UC, MEL, or ccRCC will be enrolled to confirm the tolerability of the RP2D of SRK-181 (determined in Part A2) and to evaluate the anti-tumor activity of SRK-181 in combination with an anti-PD-(L)1 antibody therapy.
Group II: Part A2: Dose EscalationExperimental Treatment2 Interventions
Part A2 will determine the MTD or MAD of SRK-181 in combination with anti-PD-(L)1 antibody therapy and will determine the RP2D of SRK-181 in combination with anti-PD-(L)1 antibody therapy for use in Part B.
Group III: Part A1: Dose EscalationExperimental Treatment1 Intervention
Part A1 will determine the maximum tolerated dose (MTD) or maximum administered dose (MAD) of SRK-181 as a single agent and will determine the recommended Phase 2 dose (RP2D) of SRK-181 as a single-agent.
Group IV: Long Term Extension Phase (LTEP)Experimental Treatment2 Interventions
Patients may continue treatment in a LTEP: * Part A1: Patients may continue treatment with SRK-181 as a single agent at the RP2D in the LTEP following 3 cycles of treatment with SRK-181 as a single agent in Part A1. * Part A2: Patients may continue treatment with SRK-181 at the RP2D in combination with anti-PD-(L)1 antibody therapy in the LTEP following 3 cycles of treatment with SRK-181 in combination with anti-PD-(L)1 antibody therapy in Part A2. * Part B: Patients may continue treatment with SRK-181 in combination with anti-PD-(L)1 antibody therapy following 9 cycles of treatment with SRK-181 in combination with anti-PD-(L)1 antibody therapy in Part B
