Loncastuximab tesirine is under clinical development by Swedish Orphan Biovitrum and currently in Phase I for Burkitt Lymphoma. According to GlobalData, Phase I drugs for Burkitt Lymphoma have a 74% phase transition success rate (PTSR) indication benchmark for progressing into Phase II. GlobalData’s report assesses how Loncastuximab tesirine’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.

Loncastuximab tesirine overview

Loncastuximab Tesirine (Zynlonta) is a CD19-directed antibody and alkylating agent conjugate, consisting of a humanized IgG1 kappa monoclonal antibody conjugated to SG3199, a pyrrolobenzodiazepine (PBD) dimer cytotoxic alkylating agent .It is formulated as lyophilized powder for solution for intravenous route of administration. Zynlonta is indicated for the treatment of adult patients with relapsed or refractory large B-cell lymphoma after two or more lines of systemic therapy, including diffuse large B-cell lymphoma (DLBCL) not otherwise specified, DLBCL arising from low-grade lymphoma, high-grade B-cell lymphoma, and B-cell non-Hodgkin Lymphoma.

loncastuximab tesirine (ADCT-402) is under development for the treatment of B-cell non-hodgkin lymphoma including Burkitt lymphoma, chronic lymphocytic leukemia (CLL), marginal zone B-cell lymphoma, extranodal marginal zone b-cell lymphoma, splenic marginal zone b-cell lymphoma, Waldenstrom macroglobulinemia (lymphoplasmacytic lymphoma),  relapsed and refractory diffuse large B-cell lymphoma, primary mediastinal large B-cell lymphoma, follicular lymphoma and mantle cell lymphoma. The therapeutic candidate is administered intravenously. The drug candidate is an antibody drug conjugate consists of a monoclonal antibody combined to pyrrolobenzodiazepines (PBD) based warheads. The drug candidate targets CD19. The warheads are developed using pyrrolobenzodiazepines (PBDs) technology. It was in Phase I stage of development for relapsed or refractory B-cell acute lymphocytic leukemia.

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.
