Phase 1a/1b Study of STK-012 Monotherapy and in Combination With Pembrolizumab in Patients With Solid Tumors

Study Purpose

This is a first-in-human, phase 1a/1b, multicenter, open-label, dose escalation study of STK-012 as monotherapy and in combination with pembrolizumab in patients with selected advanced solid tumors.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	18 Years and Over
Gender	All

More Inclusion & Exclusion Criteria

Selected Inclusion Criteria. 1. Patients must have selected tumor types and must have progressed after standard of care treatment, or be intolerant to treatment, or refused standard treatment. 2. Patients must be amenable to a fresh tissue biopsy, unless medically contraindicated. 3. Patients with central nervous system (CNS) metastases must have been treated and be asymptomatic. Selected

Exclusion Criteria:

1. Received systemic anti-cancer therapy within 3 weeks of the first dose of study treatment or small molecule kinase inhibitors within 6 elimination half-lives of the first dose of study treatment. 2. Received radiotherapy within 2 weeks of the first dose of study treatment. 3. Received prior IL-2-based or IL-15-based cytokine therapy.

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT05098132
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	Phase 1
Lead Sponsor The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.	Synthekine

Additional Details

The phase 1a portion of the study is standard 3+3 dose escalation design to evaluate STK-012 as monotherapy and in combination with pembrolizumab in patients with selected solid tumors who have progressed after standard of care treatments. The phase 1b portion of the study includes dose expansions to evaluate STK-012 as monotherapy and in combination with pembrolizumab at the candidate recommended phase 2 dose (RP2D) in selected solid tumor types.

Arms & Interventions

Arms

Experimental: Part A: STK-012 weekly (QW) monotherapy dose escalation

STK-012 will be administered in sequential ascending doses as monotherapy subcutaneously (SC) QW until unacceptable toxicity, disease progression, or withdrawal of consent.

Experimental: Part B: STK-012 every three weeks (Q3W) monotherapy dose escalation

STK-012 will be administered in sequential ascending doses as monotherapy SC Q3W until unacceptable toxicity, disease progression, or withdrawal of consent.

Experimental: Part C: STK-012 Q3W + pembrolizumab dose escalation

STK-012 will be administered in sequential ascending doses SC Q3W in combination with a fixed dose of pembrolizumab intravenously (IV) Q3W until unacceptable toxicity, disease progression, or withdrawal of consent.

Experimental: Part D: Dose expansions

STK-012 will be administered at the RP2D SC as monotherapy and in combination with a fixed dose of pembrolizumab IV Q3W until unacceptable toxicity, disease progression, or withdrawal of consent.
