Alpelisib in Combination With Carboplatin in Patients With Solid Tumors and HPV-Positive Squamous Cell Carcinoma

This phase I/II trial tests the safety, side effects, and best dose of alpelisib and whether alpelisib and carboplatin work to shrink tumors in patients with solid tumors or human papillomavirus (HPV) positive squamous cell carcinoma that has spread to nearby tissue or lymph nodes (locally advanced) or has spread to other places in the body (metastatic). Alpelisib belongs to a group of medicines called phosphatidylinositol 3-kinase (PI3K) inhibitors. This means alpelisib blocks the activity of the PI3K protein. The PI3K pathway is well known to be involved in tumor cell multiplication and survival. Blocking PI3K may reduce the ability of certain cancers to grow. Carboplatin is an anticancer drug or chemotherapy drug that binds to DNA causing damage that prevents the DNA from replicating, which prevents the cells itself from reproducing. Giving alpelisib and carboplatin may help control the disease in patients with solid tumors and HPV positive squamous cell carcinoma.
