Efficacy and Safety of Iparomlimab, an Anti-PD-1 Antibody, in Patients with Advanced Solid Tumors: A Phase 1c Study
Introduction
Iparomlimab (QL1604) is a humanized immunoglobulin G4 mAb against programmed cell death protein 1 (PD-1). Here, we report the preliminary efficacy, safety, pharmacokinetics, and immunogenicity of iparomlimab in patients with advanced solid tumors.
Methods
In this open-label, phase 1c study, patients with advanced or metastatic solid tumors, either failed or had no standard therapies available, were enrolled and received intravenous iparomlimab at 3 mg/kg once every 3 weeks. The primary efficacy endpoint was the objective response rate (ORR) assessed by the investigator per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.
Results
Between July 20, 2020, and September 6, 2021, 71 patients were enrolled and received at least one dose of iparomlimab. The ORR was 9.9% (7/71) and disease control rate was 36.6% (26/71). Median duration of response of all responders was 10.7 months [95% confidence interval (CI), 1.4-not estimable]. Additionally, the median time to progression, progression-free survival, and overall survival were 1.4 months (95% CI, 1.4–2.8), 1.4 months (95% CI, 1.4–2.7), and 9.7 months (95% CI, 7.2–15.3), respectively. A total of 52 (73.2%) patients experienced treatment-related adverse events (TRAEs) (grade ≥ 3, 19.7%). The most common TRAE (≥ 10%) was anemia (18.3%). A total of 20 (28.2%) experienced immune-related adverse events (grade ≥ 3, 7.0%). TRAEs leading to discontinuation of study drug occurred in 4 (5.6%) patients, including immune-mediated myocarditis (2 patients), Guillain–Barré syndrome (1 patient), and diarrhea (1 patient).
Conclusions
Iparomlimab showed preliminary clinical activity and had a manageable safety profile in patients with advanced solid tumors. These results support further investigation of iparomlimab as monotherapy or in combination therapy in advanced solid tumors.
Trial Registration
ClinicalTrials.gov identifier, NCT05801094. Retrospectively registered in 2023–03–24.
期刊介绍：
Advances in Therapy is an international, peer reviewed, rapid-publication (peer review in 2 weeks, published 3–4 weeks from acceptance) journal dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of therapeutics and interventions (including devices) across all therapeutic areas. Studies relating to diagnostics and diagnosis, pharmacoeconomics, public health, epidemiology, quality of life, and patient care, management, and education are also encouraged.
The journal is of interest to a broad audience of healthcare professionals and publishes original research, reviews, communications and letters. The journal is read by a global audience and receives submissions from all over the world. Advances in Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an international and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of all scientifically and ethically sound research.
