A Study of TSR-022 in Participants With Advanced Solid Tumors (AMBER)

• Status: Recruiting
• Trial end date: 2024-10-03
• Target enrollment: 0
• Participant gender: All

Summary

This is a first-in-human study evaluating the anti-T cell immunoglobulin and mucin containing protein-3 (TIM-3) antibody TSR-022. The study will be conducted in 2 parts with Part 1 consisting of dose escalation and Part 2 dose expansion. Part 1 will determine the recommended Phase 2 dose (RP2D) of TSR-022 and Part 2 will evaluate the antitumor activity of TSR-022.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Tesaro, Inc.
• Treatments: Antibodies; Antibodies, Monoclonal; Carboplatin; Docetaxel; Immunoglobulins; Nivolumab; Pemetrexed

Criteria

Inclusion Criteria

• Participant is at least 18 years of age.

• Female participants of childbearing potential must have a negative serum or urine pregnancy test within 72 hours prior to the date of the first dose of study medication or be of non-childbearing potential.

• Participant has an ECOG performance status of less than or equal to (<=)1.

• Participant has adequate organ function.

Inclusion Criteria for Participants in Part 1 and Part 2 Cohorts A, B, and C:

• Participant with advanced or metastatic solid tumor who meets the requirements for the part of the study/cohort he/she will participate in, as follows:

• Part 2: Histologically proven advanced (unresectable) or metastatic solid tumor that is measurable by computed tomography (CT) or magnetic resonance imaging (MRI) per RECIST version 1.1 criteria

• Inclusion Criteria for Participants in Part 2 Cohort D

• Participants with advanced or metastatic NSCLC that is measurable by CT or MRI per RECIST version 1.1 criteria and meet the following criteria:

• NSCLC histology includes squamous or non-squamous cell carcinoma.

• Participants have received no more than 2 prior lines of therapy, which must include a platinum-based chemotherapy (for example [e.g.], cisplatin, carboplatin) and an anti-PD-(L)1 antibody.

• Participants must have documented radiographic progression by RECIST version 1.1 criteria on prior anti-programmed cell death protein (PD)-1 or anti-PD-(L)1 therapy.

• Biopsies - If a participant has had a biopsy prior to entering the 35-day screening period and within approximately 12 weeks of study treatment, that biopsy may be accepted as the Baseline fresh biopsy.

Exclusion Criteria

• History of Grade greater than or equal to (>=)3 immune-related AE with prior immunotherapy, with the exception of non-clinically significant lab abnormalities.

• Participant has known uncontrolled central nervous system (CNS) metastases and/or carcinomatous meningitis.

• Participant has a known additional malignancy that progressed or required active treatment within the last 2 years. Participants with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen may be included only after discussion with the Medical Monitor.

• Participant is considered a poor medical risk due to a serious, uncontrolled medical disorder, nonmalignant systemic disease or active infection requiring systemic therapy.

• Participant is pregnant or breastfeeding, or expecting to conceive children within the projected duration of the study, starting with the Screening Visit through 150 days after the last dose of study treatment.

• Participant has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of study treatment.

Exclusion Criteria for Participants in Part 2 Cohort D

• A participant with negative (as determined by Central Testing Lab) or unevaluable TIM-3 expression from tissue obtained prior to study entry will not be eligible for the study.

• Participant has received prior therapy as defined below:

• Prior treatment with anti-PD-1, anti-PD-L1, or anti-PD-L2 agent that resulted in permanent discontinuation due to an AE.

• Prior treatment with an anti-lymphocyte activation gene (LAG)-3 or anti-TIM-3.

• Radiologic or clinical progression <= 8 weeks after initiation of prior anti-PD-1 or anti-PD-L1 antibody.

• Participants with known epidermal growth factor receptor (EGFR) mutation, anaplastic lymphoma kinase (ALK) translocation, or ROS1 mutation.

• Participant has received a vaccine other than a vaccine against severe acute respiratory syndrome (SARS)-coronavirus 2 (CoV-2) infection ("Coronavirus Disease 2019" [COVID-19]) within 7 days of planned start of study therapy. The use of all COVID-19 vaccines is allowed, with the exception of COVID-19 vaccines using the recombinant adenoviral vector platform within 30 days of planned start of study therapy. If a COVID-19 vaccine using this platform is to be administered within 30 days of planned start of study therapy, this must first be discussed with and approved by the Sponsor's Medical Monitor.
