AdvanTIG-105: a phase I/Ib dose-expansion study of ociperlimab plus tislelizumab with or without chemotherapy in metastatic non-small cell lung cancer and extensive-stage small cell lung cancer.
Article in Journal for immunotherapy of cancer, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04047862 (Phase 1/1b Study Investigating Safety, Tolerability, PK and Antitumor Activity of Anti-TIGIT Monoclonal Antibody BGB-A1217 in Combination With Anti-PD-1 Monoclonal Antibody Tislelizumab in Patients With Advanced Solid Tumors), which is not on this map.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it

Abstract
backgroundPatients with metastatic non-small cell lung cancer (NSCLC) or extensive-stage small cell lung cancer (ES-SCLC) have poor prognosis and survival with current standard of care. Several checkpoint inhibitor combinations have been evaluated clinically. We report outcomes from the dose-expansion cohorts of patients with NSCLC or ES-SCLC from the AdvanTIG-105 clinical trial.
methodsAdvanTIG-105 was a phase I/Ib, open-label, multicenter clinical trial of ociperlimab plus tislelizumab with or without chemotherapy in patients with unresectable locally advanced or metastatic solid tumors, including NSCLC and ES-SCLC (NCT04047862). The dose-expansion cohorts received ociperlimab (anti-T-cell immunoglobulin and immunoreceptor tyrosine-based inhibitor motif domain) 900 mg intravenously and tislelizumab (anti-programmed cell death-protein 1) 200 mg intravenously every 3 weeks (Q3W) ± chemotherapy for four cycles, followed by ociperlimab 900 mg intravenously and tislelizumab 200 mg intravenously Q3W. The primary endpoint was the objective response rate. Other key endpoints included duration of response and safety.
resultsAs of August 7, 2024, patients with untreated squamous NSCLC (sqNSCLC; n=41), untreated non-sqNSCLC (n=43), untreated programmed cell death-ligand 1+ NSCLC (tumor cell ≥1%; n=45), checkpoint inhibitor-experienced NSCLC (n=26), and untreated ES-SCLC (n=43) were treated in the dose-expansion phase; of these, 40, 42, 45, 26, and 41 patients, respectively, were efficacy evaluable. ORR (95% CI) was 55.0% (38.5% to 70.7%), 54.8% (38.7% to 70.2%), 40.0% (25.7% to 55.7%), 7.7% (0.9% to 25.1%), and 65.9% (49.4% to 79.9%), respectively. Median (95% CI) DOR was 16.9 (5.6 to not estimable (NE)), 13.9 (8.2 to NE), 14.0 (2.9 to NE), 15.9 (12.6 to NE), and 4.1 (3.4 to 5.6) months, respectively. Median (95% CI) progression-free survival was 8.2 (6.0 to 18.1), 11.3 (8.0 to 20.7), 5.5 (4.2 to 8.2), 2.9 (1.4 to 5.3), and 4.9 (4.2 to 5.5) months, respectively. Treatment-related treatment-emergent adverse events (TR-TEAEs) were experienced by 39 (95.1%), 41 (95.3%), 38 (84.4%), 19 (73.1), and 39 (90.7%) patients, respectively, with 24 (58.5%), 26 (60.5%), 9 (20.0%), 6 (23.1%), and 23 (53.5%) experiencing Grade 3-4 TR-TEAEs.
conclusionsOciperlimab and tislelizumab±chemotherapy demonstrated a manageable safety profile and preliminary antitumor activity in patients with NSCLC or ES-SCLC. Findings from this small phase I study should be interpreted with caution.
