Aim: TAK-981 is a highly effective and selective inhibitor of the small ubiquitin-like modifier (SUMO) activating enzyme, and it promotes the expression of type I interferons (IFN-Is). Developing a sensitive bioanalytical assay for quantitating TAK-981 is essential in the clinical investigations for oncology drug development.
Materials & Methods: TAK-981 and its stable isotope labeled compound (TAK-981C, N) as the internal standard were employed in this LC-MS/MS assay.
Results: This assay was successfully validated from 0.1 ng/mL to 100 ng/mL with good accuracy and precision and has been applied to support clinical studies.
Conclusion: A sensitive and robust LC-MS/MS assay was validated for TAK-981 in human plasma for the first time.

Pet dogs spontaneously develop a form of diffuse large B cell lymphoma (DLBCL) that recapitulates many of the features of double hit () human DLBCL. We recently completed a clinical trial in dogs with DLBCL using a combination of canine anti-CD20 antibody and low dose doxorubicin followed by one of three small molecule immune-modulating agents (KPT-9274, TAK-981 or RV1001). Clinical outcomes and tumor specific biomarkers of response from these dogs have been previously reported.

Synovial sarcoma (SySa) is an aggressive soft tissue sarcoma with an urgent need to develop targeted therapies. Here, we exploited specific vulnerabilities created by transcriptional rewiring by the fusion protein SS18::SSX, the sole oncogenic driver in SySa. To uncover genes that are selectively essential for the fitness of SySa cells compared to other tumor cell lines, we mined the Cancer-Dependency-Map data.

: Accumulating evidence indicates that neutrophils undergo reprogramming of their effector functions as they migrate from the bloodstream into an inflamed tissue. Here, we examined the role of the small ubiquitin-like modifier (SUMO) conjugation in modulating neutrophil functional changes in the inflammatory microenvironment. : Primary human and murine neutrophils were used to assess SUMOylation levels in vitro by Western blotting and results were validated in clinical samples from patients undergoing surgery involving hypothermic circulatory arrest.

Rhabdomyosarcoma (RMS) is a highly aggressive pediatric soft tissue sarcoma with limited therapeutic options, particularly for cases resistant to conventional treatments. The SUMOylation pathway, which plays a key role in regulating the cell cycle, apoptosis, and transcription, has emerged as a potential therapeutic target in RMS. Elevated levels of SUMO1 and SUMO2/3 conjugates in RMS cell lines, compared to normal human skeletal muscle cells, underscore the association between upregulated SUMOylation and aggressive cancer phenotypes.
