CDK9 inhibition as a potential therapeutic strategy in Ewing sarcoma
(AACR 2023)

[VIRTUAL] Pharmacodynamic biomarker strategies for CDK9 inhibition
(AACR-II 2020)
- P1 | "TP-1287 is a novel oral prodrug of alvocidib, a potent CDK9 inhibitor, and is currently under clinical investigation in patients with advanced solid tumors (clinicaltrials.gov, NCT03604783). Taken together, TP-1287 demonstrated potent cell and tumor growth inhibition in multiple hematological cell lines, including AML and MM. Furthermore, a newly established flow cytometry system for p-RPB1 and MCL-1 to evaluate CDK9 inhibition in human PBMCs was developed, which could be useful as a surrogate biomarker for TP-1287 in clinical trials and warrants further investigation."

Phosphate moiety in FDA-approved pharmaceutical salts and prodrugs.
(PubMed, Drug Dev Res)
- "Histamine phosphate is the first phosphate salt, and hydrocortisone phosphate was the first prodrug approved by FDA in 1939 and 1952, respectively...Phosphate prodrugs, namely combretastatin A-4 diphosphate, combretastatin A-4 phosphate, lufotrelvir, TP-1287, pyridoxal phosphate, riboflavin phosphate, and psilocybin are clinical candidates. This review focuses on the FDA-approved phosphate salts and prodrugs from 1939 to 2021. The biopharmaceutical advantage of phosphate salts and prodrugs over the parent molecule is also deliberated."

Tolero Pharmaceuticals presents biomarker identification strategies for investigational agents alvocidib and TP-1287 at AACR Virtual Meeting II 2020
(PRNewswire)
- "In preclinical studies, TP-1287 and alvocidib also showed potent cell-based activity in vitro and tumor growth inhibition in vivo across multiple hematologic cell lines, including acute myeloid leukemia (AML) and multiple myeloma (MM). Alvocidib was found to suppress p-RPB1 and the transcription of MCL-1, both downstream effectors of CDK9 activation, across cell lines and in normal PBMCs. Separately in a MM xenograft model, TP-1287 was shown to inhibit tumor growth, suppress p-RPB1 and the transcription MCL-1, and induce apoptosis."

Targeting CDK9 and MCL1 in castration-sensitive and resistant prostate cancer models
(AACR-NCI-EORTC 2019)
- "Here, we describe tumor growth inhibition in CRPC models using the CDK9 inhibitor TP-1287, an oral alvocidib prodrug, alone and in combination with docetaxel or venetoclax, a BCL-2 inhibitor that is currently being evaluated in a Phase II clinical trial for metastatic CRPC. TP-1287 treatment (1.25 mpk BID) in combination with 100 mpk venetoclax demonstrated 64% tumor growth inhibition in the 22Rv1 CRPC model that was resistant to docetaxel, enzalutamide and venetoclax alone. These data support the potential of TP-1287 to be used in combination with currently available or novel therapies to achieve better efficacy for androgen sensitive and CRPC patients."
