Dostarlimab is under clinical development by GSK and currently in Phase I for Metastatic Breast Cancer. According to GlobalData, Phase I drugs for Metastatic Breast Cancer have an 83% phase transition success rate (PTSR) indication benchmark for progressing into Phase II. GlobalData’s report assesses how Dostarlimab’s drug-specific PTSR and Likelihood of Approval (LoA) scores compare to the indication benchmarks. Buy the report here.

GlobalData tracks drug-specific phase transition and likelihood of approval scores, in addition to indication benchmarks based off 18 years of historical drug development data. Attributes of the drug, company and its clinical trials play a fundamental role in drug-specific PTSR and likelihood of approval.

Dostarlimab overview

Dostarlimab (Jemperli) is a immunoglobulin G4 humanized monoclonal antibody, acts as anti neoplastic agent. It is formulated as solution and concentrate solution for intravenous route of administration. Jemperli is indicated as monotherapy for the treatment of adult patients with mismatch repair deficient (dMMR)/microsatellite instability-high (MSI-H) recurrent or advanced endometrial cancer (EC) that has progressed on or following prior treatment with a platinum-containing regimen.

Dostarlimab is under development for the treatment of solid tumors including gastric cancer, high-grade neuroendocrine carcinoma, advanced small cell lung cancer, adenocarcinoma of the gastroesophageal junction, head and neck cancer, biliary tract cancer, clear cell renal cell carcinoma, metastatic urothelial bladder cancer, triple negative breast cancer, refractory osteosarcoma, colorectal cancer, neuroblastoma, adrenocortical carcinoma, ewing sarcoma, rhabdomyosarcoma, metastatic pancreatic ductal adenocarcinoma, recurrent and metastatic head and neck squamous cell carcinoma, squamous non-small cell lung cancer, malignant pleural mesothelioma, cervical cancer, rectal adenocarcinoma, acral melanoma, metastatic microsatellite instability high (MSI-H) endometrial cancer, epithelial ovarian cancer, metastatic clear cell sarcoma, peritoneal cancer, gestational trophoblastic neoplasia (GTN), fallopian tube cancer, penile cancer who have progressed following one or two prior chemotherapy treatments and first line/second line non-small cell lung cancer and pan-deficient mismatch repair tumors (PdMMRT) (solid tumor). It is administered intravenously. It is an anti-PD-1 mAb. The drug candidate acts by targeting the PD-1 which has the potential to activate anti-tumor immunity. The drug candidate is developed based on somatic hypermutation (SHM) technology platform (SHM-XEL platform).

GlobalData, the leading provider of industry intelligence, provided the underlying data, research, and analysis used to produce this article.

GlobalData’s Likelihood of Approval analytics tool dynamically assesses and predicts how likely a drug will move to the next stage in its clinical pathway (PTSR), as well as how likely the drug will be approved (LoA). This is based on a proprietary algorithm built from the drugs’ sales forecast, regulatory milestones, cost forecasts, WACC rate and other proprietary data sources found on GlobalData’s Pharmaceutical Intelligence Center.
