Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Drugs - Lomvastomig

Experimental: Dose Escalation Part A: Once Every 2 Weeks (Q2W) - Lomvastomig will be administered in treatment cycles once every 2 weeks (Q2W). Dose escalation will be carried out according to a modified continual reassessment method (mCRM) with escalation with overdose control (EWOC) design.

Experimental: Expansion Part B1: Metastatic Melanoma Cohort - This cohort will comprise participants with checkpoint inhibitor (CPI) experienced, second line and beyond metastatic melanoma. The starting dose of lomvastomig for Expansion will be derived from the maximum tolerated dose (MTD)/recommended dose for expansion (RDE) and the best dosing schedule determined during Dose Escalation.

Experimental: Expansion Part B2: NSCLC Cohort 1 - This cohort will comprise participants with CPI and platinum experienced, second or third line PD-L1 positive non-small cell lung cancer (NSCLC). The starting dose of lomvastomig for Expansion will be derived from the MTD/RDE and the best dosing schedule determined during Dose Escalation.

Experimental: Expansion Part B3: NSCLC Cohort 2 - This cohort will comprise participants with PD-L1 high, cancer immunotherapy (CIT) naïve first line NSCLC. The starting dose of lomvastomig for Expansion will be derived from the MTD/RDE and the best dosing schedule determined during Dose Escalation.

Experimental: Expansion Part B4: SCLC Cohort - This cohort will comprise participants with CPI naïve small cell lung cancer (SCLC) with prior failure of, progression on, or intolerance to, standard therapy. The starting dose of lomvastomig for Expansion will be derived from the MTD/RDE and the best dosing schedule determined during Dose Escalation.

Experimental: Expansion Part B5: ESCC Cohort - This cohort will comprise participants with CPI-naïve esophageal squamous cell carcinoma (ESCC). The starting dose of lomvastomig for Expansion will be derived from the MTD/RDE and the best dosing schedule determined during Dose Escalation.


Treatment: Drugs: Lomvastomig
Lomvastomig will be administered intravenously (IV) with a flat dose on the schedule described for each study arm.

Summary
Brief summary
This is a first-in-human, open-label, multicenter, Phase I multiple-ascending dose (MAD) study of single agent lomvastomig (RO7121661), an anti PD-1 (programmed death-1) and TIM-3 (T-cell immunoglobulin and mucin domain 3) bispecific antibody, for participants with advanced and/or metastatic solid tumors. The study consists of 2 parts: Dose Escalation (Part A) and Expansion (Parts B1, B2, B3, B4, and B5). The Dose Escalation part will be conducted first to determine the maximum tolerated dose (MTD) and/or recommended dose for expansion (RDE) based on safety, tolerability, pharmacokinetic, and/or the pharmacodynamic profile of escalating doses of lomvastomig. The Expansion part will enroll tumor-specific cohorts to evaluate anti-tumor activity of the MTD and/or RDE of lomvastomig from Part A (Q2W) and to confirm safety and tolerability in participants with selected tumor types.
