To Evaluate the Efficacy and Safety of Tislelizumab in Combination With Lenvatinib in Participants With Selected Solid Tumors

BeiGene58 enrolled

Overview

This clinical trial evaluated the safety and potential benefits of combining two cancer treatments, tislelizumab and lenvatinib, in Chinese participants with advanced or metastatic cancers, including lung, head and neck, bladder, kidney, and stomach cancer. The study included two parts: the first part assessed how safe the drug combination was, and the second part examined how well it worked. A small group of participants initially received the drugs to determine the appropriate dose, and if the treatment was well tolerated, additional participants were treated at that dose. Participants remained on the treatment unless their cancer progressed, they experienced serious side effects, or they chose to stop.

Key Inclusion Criteria: 1. Participants had signed an informed consent form and were able to comply with all study requirements. 2. Participants had a histologically and/or cytologically confirmed diagnosis of advanced solid tumors, which included one of the following types: * Non-Small Cell Lung Cancer (NSCLC) * Squamous Cell Carcinoma of the Head and Neck (SCCHN) * Gastric Cancer (GC) * Urothelial Carcinoma (UC) * Renal Cell Carcinoma (RCC) 3. Participants had at least one measurable lesion as defined by the Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1. 4. Tumor tissue samples (approximately 10 unstained slides) were provided for central laboratory assessment of programmed death-ligand 1 (PD-L1) expression in the NSCLC cohort during the screening period. These samples were also used for retrospective exploratory biomarker analyses related to treatment response and resistance across the NSCLC, SCCHN, UC, or Gastric Cancer (GC) cohorts, in a central or designated test laboratory approved by BeiGene. 5. Participants had an Eastern Cooperative Oncology Group (ECOG) performance of 0 or 1 Key Exclusion Criteria: 1. For participants in the NSCLC cohort, those with active leptomeningeal disease or uncontrolled, untreated brain metastases were excluded. In cohorts other than NSCLC, any participant with known leptomeningeal disease or brain metastases was excluded. 2. Participants who had received prior therapy with lenvatinib, or with antibodies targeting programmed cell death protein 1 (PD-1), programmed death-ligand 1 (PD-L1), programmed death-ligand 2 (PD-L2), or any other agents specifically targeting T-cell costimulatory or immune checkpoint pathways, were excluded. 3. Participants with a history of interstitial lung disease, non-infectious pneumonitis, or any uncontrolled pulmonary conditions (including but not limited to pulmonary fibrosis or acute lung diseases) were excluded. 4. Participants who were unable to swallow capsules, or who had diseases or previous procedures that significantly affected gastrointestinal function such as malabsorption syndrome, surgical resection of the stomach or small bowel, bariatric surgery, symptomatic inflammatory bowel disease, or partial/complete bowel obstruction were excluded. 5. Participants who had experienced clinically significant bleeding (classified as Grade 2 or higher according to the Common Terminology Criteria for Adverse Events \[CTCAE\]) within 21 days prior to the first dose were excluded. Note: Additional protocol-defined inclusion and exclusion criteria may have applied.

Outcomes

Primary Outcomes

Safety Run-in: Number of Participants With Adverse Events (AEs)

An adverse event refers to any unintended or unfavorable sign, symptom, or condition (including abnormal lab results) that occurs during the study, regardless of whether it is related to the study drug. A serious adverse event (SAE) is any untoward medical occurrence that, at any dose: * Resulted in death * Was life-threatening * Required hospitalization or prolongation of existing hospitalization * Resulted in disability/incapacity * Was a congenital anomaly/birth defect * Was considered a significant medical AE by the investigator based on medical judgement. A dose-limiting toxicity (DLT) was defined as a Grade 3 or 4 hematologic or nonhematologic toxicity occurring during the DLT assessment window and deemed related to one or more study drugs by the investigator.

Time frame: From first dose through the end of the safety run-in part, up to 124 days; The DLT observation period was 28 days after first dose.

Overall Response Rate (ORR)

Overall response rate is defined as the percentage of participants who had a confirmed complete response (CR) or partial response (PR) as assessed by the investigator per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 Tumor assessments. CR is defined as the disappearance of all target and non-target lesions and no new lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \< 10 mm. PR is defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.
