    Epigenetic reprogramming of stromal-epithelial crosstalk to improve immunotherapy response in pancreatic ductal adenocarcinoma (Section 49) -  Mar 17, 2026 - Abstract #AACR2026AACR_9396;    
    Ongoing spatial multiplex imaging and RNA-seq analyses aim to correlate in vivo immune and stromal changes with in vitro findings, supporting rational combination strategies. This epigenetic screening platform provides a predictive framework to evaluate compounds that overcome CAF-mediated immune exclusion and modulate the tumor microenvironment, offering new avenues to enhance PDAC responsiveness to diverse immunotherapies.

    Targeting high risk osteosarcoma: MYC modulation alters metastasis (Section 45) -  Mar 17, 2026 - Abstract #AACR2026AACR_3249;    
    Nevertheless, the top hit of the screen, samuraciclib, convincingly reverses MYC activity and the associated metastatic phenotype and is undergoing additional testing in metastatic OS mouse models and a canine clinical trial is under development. Correlative biology such as spatial transcriptomics will be used to guide the translation of samuraciclib to patients with high risk osteosarcoma.

    The liquid biomarker thymidine kinase activity reflecting proliferation rate can provide guidance in drug development and address Project Optimus (Section 45) -  Mar 5, 2024 - Abstract #AACR2024AACR_9083;    
    After initiation of samuraciclib treatment, a CDK7 inhibitor, a significant reduction in TKa levels in blood from metastatic breast cancer (MBC) patients was observed, indicating inhibition of cell cycle progression...MBC patients monitored >3 months and showing low TKa levels have very low likelihood of progression within 30- to 60 days, <2% and <6%, respectively. TKa is a translational liquid biomarker that bridges results between preclinical and clinical studies, providing fundamental information for drug development decision making.

    Journal:  Active growth signaling promotes senescence and cancer cell sensitivity to CDK7 inhibition. (Pubmed Central) -  Nov 22, 2023   
    We show that CDK7i, by samuraciclib, induces a permanent cell-cycle exit, known as senescence, without promoting DNA damage signaling or cell death...Reverting a growth-promoting mutation in PIK3CA to wild type decreases sensitivity to CDK7i. Our work establishes that enhanced growth alone promotes CDK7i sensitivity, providing an explanation for why some cancers are more sensitive to CDK inhibition than normally growing cells.

    TACTIVE-U: phase 1b/2 umbrella study of vepdegestrant, a PROteolysis TArgeting Chimera (PROTAC) estrogen receptor (ER) degrader, combined with other anticancer treatments in ER (Hall 2-3) -  Nov 4, 2023 - Abstract #SABCS2023SABCS_962;    
    P1/2, P1b/
    The cyclin-dependent kinase (CDK)4/6 inhibitors abemaciclib and ribociclib are approved in combination with an aromatase inhibitor or fulvestrant, or as monotherapy (abemaciclib), for ER+/HER2- advanced or metastatic breast cancer...Vepdegestrant is being evaluated in combination with abemaciclib (sub-study A; NCT05548127), ribociclib (sub-study B; NCT05573555), and samuraciclib (sub-study C)...The phase 2 portion of each sub-study will further evaluate the antitumor activity of the combinations; the primary endpoint is objective response and secondary endpoints include antitumor activity (CBR and DOR), PFS, overall survival, safety, plasma concentration of study drugs, and changes in circulating tumor DNA. Future combination sub-studies will be included in TACTIVE-U.

    Furthermore, TIMP1 expression was positively correlated with that of ferroptosis-related genes, such as GPX4 and HSPA5. TIMP1 can be used as a biomarker for colorectal cancer and is associated with the immunological microenvironment, drug sensitivity, and ferroptosis inhibition in this disease.
  • ||||||||||  TY-2699a is a highly potent CDK7 inhibitor to abolish dysfunctional tumor cell cycle for clinical development (Section 9; Poster Board #10) -  Mar 14, 2023 - Abstract #AACR2023AACR_8576;    
    P1
    Currently, trilaciclib, palbociclib, ribociclib, and abemaciclib that bear dual specificities against CDK4 and CDK6 have been approved for clinical usage, and more CDK4/6 targeted agents are actively under clinical evaluations, among which, TY-302, a novel CDK4/6 inhibitor being developed by TYK Medicines, is under Phase II trial (NCT04433494)...Several CDK7 targeted agents, such as SY-5609 and Samuraciclib (CT7001), are under development...# Shengli Dong and Apeng Liang contributed equally to this work. * Jun Li, Shengli Dong and Apeng Liang are the correspondent authors.

    Defining modulators of response to samuraciclib, a CDK7 inhibitor for breast cancer (Section 15; Poster Board #5) -  Mar 14, 2023 - Abstract #AACR2023AACR_3838;    
    In conclusion, our findings highlight the importance of an active mTOR/PI3K pathway in promoting response to Samuraciclib. This may help guide patient treatments and development of effective combination therapies.
