RNA interference screen against SARS-CoV-2 identifies proviral vesicular transport factors involved in release. (PubMed, J Gen Virol) - "A cluster of proviral factors involved in vesicle-mediated exocytic transport was confirmed to be involved in virus production in the 'European original' and variants Delta and Omicron. Inhibiting proviral Rab11a-mediated cargo delivery with cyclin-dependent kinase 9 inhibitor-73 prevented SARS-CoV-2 release, highlighting potential new mechanisms of action for host-targeting antivirals."

QHRD107 (CDK9 Inhibitor), venetoclax, and azacitidine combination therapy (107VA regimen) in relapsed/refractory Acute Myeloid Leukemia: Data updates and subgroup analysis (ASH 2025) - P2 | "The 107VA regimen demonstrated high response rates in VEN-AZA relapse or refractoryAML, particularly in patients with TP53 mutations and myelodysplasia-related features. Based on thesedata, a phase 2b randomized controlled study comparing 107VA with other salvage regimens is currentlybeing conducted for patients who relapse after VEN-AZA treatment."

High Remission Rates in Relapsed/Refractory Acute Myeloid Leukemia with QHRD107 (CDK9 Inhibitor), Venetoclax, and Azacitidine Combination Therapy (107VA regimen) : Preliminary Results of a Phase 2a Study (ASH 2024) - P1, P2 | "Common non-hematologic treatment-related adverse effects (TRAE) included diarrhea (66.7%, 4.2% ≥ G3), hypokalemia (50.0%, 8.3% ≥ G3), hepatic injury (50.0%), vomiting (45.8%), nausea (33.3%), infection (41.7%, 25.0% ≥ G3), and lactate dehydrogenase increase (29.2%). Conclusions : The 107VA regimen was well tolerated at tested doses and showed preliminarily activity in patients, with a high rate of cCR rate observed in those resistant to VEN-AZA therapy."

CDK9 inhibition inhibits multiple oncogenic transcriptional and epigenetic pathways in prostate cancer. (PubMed, Br J Cancer) - "Our work demonstrates that CDK9 inhibition disrupts multiple oncogenic pathways and positions CDKI-73 as a promising therapeutic agent for prostate cancer, particularly aggressive, therapy-resistant subtypes."
