INK4A/B as predictive biomarkers for enhanced efficacy of dual WEE1 and PKMYT1 inhibition in CDK4/6 inhibitor-resistant breast cancer (AACR 2025) - "This study aimed to identify predictive biomarkers of response to WEE1/PKMYT1 dual inhibition while maintaining manageable toxicity. Evaluating WEE1 inhibitors (adavosertib or azenosertib) in combination with the PKMYT1 inhibitor (lunresertib) across CDK4/6i-R and TNBC models, including patient-derived xenografts (PDXs) and organoids, demonstrated significant tumor suppression, with the novel dual WEE1/PKMYT1 inhibitor SGR-3515 showing comparable efficacy... Dual inhibition of WEE1 and PKMYT1 presents a compelling therapeutic strategy for CDK4/6i-R breast cancer and TNBC. Elevated baseline levels of INK4A and INK4B are strongly associated with enhanced treatment responses, highlighting their potential as predictive biomarkers for selecting patients likely to benefit from WEE1/PKMYT1 dual inhibition therapy."

Optimization of therapeutic index of SGR-3515, a first-in-class Wee1/Myt1 inhibitor through intermittent dosing for monotherapy and combination with chemotherapy in xenograft tumor models (AACR 2025) - P1 | "Furthermore it suppresses the acquired resistance associated with a Wee1 inhibitor (ZNc3). The robust anti-tumor activity of SGR-3515, a first-in-class Wee1/Myt1 inhibitor confirms the synergy of Wee1 and Myt1 co-inhibition. SGR-3515 dosing schedule optimization improves therapeutic index as a monotherapy and in combination with Carboplatin. The preclinical data supported the progression of SGR-3515 to clinical study (NCT06463340)."

Machine learning-based combination prediction for Wee1 inhibitor (AACR 2025) - "Motivation: Wee1 is the gatekeeper gene that allows proper DNA damage repair (DDR) during the G2/M cell cycle transition. We integrated drug combination response data from two publications and trained LTR models based on the data. In 5-fold cross-validations for the different prediction scenarios, new entry, new matrix, new drug combo, the model achieved a Pearson correlation of above 0.8 between predicted and measured response data. The final model was trained to predict responses of drug combinations between Wee1i and 130 other drugs in 53 cell lines."

Discovery of SGR-3515, a first-in-class Wee1/Myt1 inhibitor with differentiated pharmacological properties in xenograft tumor models (EORTC-NCI-AACR 2024) - "SGR-3515 demonstrates an unique and well differentiated pharmacological profile compared to the Wee1 inhibitor ZN-c3 or the Myt1 inhibitor RP-6306 in preclinical studies. It mediates durable pharmacological effects that enable long dosing holidays to reduce potential on-target myelosuppression and GI toxicity. In addition, the dual inhibition of Wee1 and Myt1 has synergistic effect and drives deeper anti-tumor responses than inhibiting either target alone."

Discovery of potent, selective, and orally available WEE1 inhibitors that demonstrate increased DNA damage and mitosis in tumor cells leading to tumor regression in vivo (AACR 2022) - "Small molecule WEE1 inhibitors, such as AZD1775 and Zn-C3, are currently being evaluated in the clinic and have demonstrated promising efficacy in solid tumors including ovarian, colon, and uterine carcinoma.By applying Schrödinger’s computational platform including Free Energy Perturbation (FEP) and Protein FEP, we have identified novel, potent, and highly selective WEE1 inhibitors with IC50 values in the low nanomolar range in a biochemical kinase activity assay and cellular target engagement (CDK1 pTyr15) IC50s of 100 - 300 nM in A427 and OVCAR3 cell lines.
