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.

Pacritinib overview

PacritInib (Vonjo) is an anti neoplastic agent. It is formulated as hard capsules for oral route of administration, Vonjo is indicated for the treatment of adults with intermediate or high-risk primary or secondary (post-polycythemia vera or post-essential thrombocythemia) myelofibrosis with a platelet count below 50×109/L.

Pacritinib (BAX 2201, SB-1518, ONX-0803) is under development for the treatment of peripheral T-cell lymphoma, angioimmunoblastic T-cell lymphoma/follicular helper T-cell (AITL/TFH) cutaneous T-cell lymphoma mycosis fungoides (MF) and Sezary syndrome (SS), myelofibrosis, post-polycythemia vera myelofibrosis, post-essential thrombocythemia myelofibrosis and graft versus host disease (GVHD). It is administered orally. It targets JAK2-selective kinase, FMS-like tyrosine kinase 3,colony stimulating factor 1 receptor (CSF1R) and interleukin-1 receptor-associated kinase 1 (IRAK1).

It was also under the development for the treatment of myelodysplastic syndrome, colorectal cancer, acute myelocytic leukemia (AML), chronic myelomonocytic leukemia (CMML), chronic lymphocytic leukemia (CLL) and lymphomas (mantle cell lymphoma, Hodgkin lymphoma, indolent lymphoma), coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
