Phase 1b Clinical Trial with Alpelisib plus Olaparib for Patients with Advanced Triple-Negative Breast Cancer

Felipe Batalini et al.

Summary: This study aimed to evaluate the safety and recommended dose of olaparib in combination with alpelisib in patients with breast cancer, and explore its effects on different subtypes. The results showed that this combination therapy was tolerable for pre-treated TNBC patients and demonstrated activity in non-BRCA mutant patients. Analysis of circulating-free DNA also provided important prognostic information.

RTK-Dependent Inducible Degradation of Mutant PI3Kα Drives GDC-0077 (Inavolisib) Efficacy

Kyung W. Song et al.

Summary: The PI3K inhibitors GDC-0077 and taselisib have a unique mechanism of action by degrading mutant p110a protein, leading to more potent inhibition of mutant PI3K pathway signaling and cell viability, and better maintenance of prolonged pathway suppression.

Discovery of GDC-0077 (Inavolisib), a Highly Selective Inhibitor and Degrader of Mutant PI3Kα

Emily J. Hanan et al.

Summary: This study optimized a series of benzoxazepin-oxazolidinone ATP-competitive inhibitors of PI3K alpha that also induce selective degradation of the mutant p110 alpha protein. Structure-based design led to potent inhibitors with over 300-fold selectivity and further optimization of pharmacokinetic properties resulted in excellent in vivo efficacy. Clinical candidate GDC-0077 (inavolisib) is now being evaluated in a Phase III clinical trial for treating patients with PIK3CA-mutant breast cancer.

Glucose Enhances Pro-Tumorigenic Functions of Mammary Adipose-Derived Mesenchymal Stromal/Stem Cells on Breast Cancer Cell Lines

Maria Rosaria Ambrosio et al.

Summary: This study demonstrates that high glucose levels enhance the aggressiveness of breast cancer cells and promote a pro-tumorigenic phenotype in mammary adipose tissue-derived mesenchymal stromal/stem cells (MAT-MSCs). The findings suggest that metabolic control may be important for reducing cancer outgrowth and preserving the functions of the adipose microenvironment.

A Phase Ib Study of Alpelisib or Buparlisib Combined with Tamoxifen Plus Goserelin in Premenopausal Women with HR-Positive HER2-Negative Advanced Breast Cancer

Yen-Shen Lu et al.

Summary: This study evaluated the efficacy and safety of alpelisib or buparlisib in combination with tamoxifen and goserelin in premenopausal patients with HR+, HER2(-) ABC. The RP2Ds of alpelisib and buparlisib were established at 350 mg and 100 mg, respectively, with no unexpected safety findings. The progression-free survival was slightly longer in the alpelisib group compared to the buparlisib group.

Summary: The study evaluated the safety and tolerability of dual inhibition of the CDK4/6 and PI3K pathways in patients with HR+, HER2(-) ABC, showing that the combination of ribociclib and fulvestrant is safe for treatment. However, triple combinations with alpelisib or buparlisib plus fulvestrant are not recommended for further investigation.

Phase I Basket Study of Taselisib, an Isoform-Selective PI3K Inhibitor, in Patients with PIK3CA-Mutant Cancers

Komal Jhaveri et al.

Summary: This study demonstrated limited activity of the PI3K inhibitor taselisib in PIK3CA-mutant cancers, with varying response rates based on mutation subtype and tumor type. Genomic analyses identified potential resistance mechanisms to PI3K inhibition and indicated a narrow therapeutic index for taselisib. These findings contribute to a better understanding of the activity, limitations, and resistance mechanisms of PI3K inhibitors as monotherapy for PIK3CA-mutant tumors.
