A012303: SHORTSTOP-HER2: SHORTENED DURATION OF ADJUVANT THERAPY IN PATIENTS WITH EARLYSTAGE HER2+ BREAST CANCER WHO ACHIEVE PCR AFTER NEOADJUVANT CHEMOTHERAPY WITH HER2 BLOCKADE

Cancer Internal Medicine Breast Cancer Digestive Disease Adult Subjects

This phase III trial compares 6 months of human epidermal growth factor receptor 2 (HER2)-targeted therapy to 12 months of HER2-targeted therapy for the treatment of HER2-positive (+) breast cancer in patients that had a pathologic complete response (pCR) after preoperative (neoadjuvant) chemotherapy with trastuzumab. Trastuzumab and pertuzumab are monoclonal antibodies and forms of targeted therapy that attach to a receptor protein called HER2. HER2 is found on some cancer cells. When trastuzumab or pertuzumab attach to HER2, the signals that tell the cells to grow are blocked and the tumor cell may be marked for destruction by the body's immune system. Giving 6 months of HER2-targeted therapy may work better than giving 12 months for the treatment of HER2+ breast cancer in patients that had a pCR after neoadjuvant chemotherapy with trastuzumab.

A Phase 1, First-in-Human, Open-Label Study to Evaluate the Safety, Tolerability, PK, and Preliminary Anti-tumor Activity of the Novel Oral Selective CDK2/4 Dual Degrader NKT5097 in Adults with Advanced/Metastatic Solid Tumors

Cancer Internal Medicine Breast Cancer Adult Subjects

The goal of this open-label dose escalation and expansion study is to evaluate the safety and tolerability of NKT5097 in adults with advanced/metastatic tumors (emphasis on breast cancer and solid tumors with CCNE1 amplification). Main questions to answer include:

* What is the recommended dose for expansion and/or Phase 2, for both monotherapy and in combination with ET
* What medical issues/symptoms do participants experience when taking NKT5097 as monotherapy as well as in combination with ET

First-in-Human Study of Tersolisib (STX-478), a Mutant-Selective PI3Ka; Inhibitor as Monotherapy and in Combination With Other Antineoplastic Agents in Participants With Advanced Solid Tumors

Cancer Internal Medicine Breast Cancer Adult Subjects

Study STX-478-101 (LY4064809) is a multipart, open-label, phase 1/2 study evaluating the safety, tolerability, pharmacokinetics (PK), and preliminary antitumor activity of STX-478 (LY4064809) in participants with advanced solid tumors with P13Ka mutations.

Part 1 will evaluate STX-478 as monotherapy in participants with advanced solid tumors. Part 2 will evaluate STX-478 therapy as combination therapy with fulvestrant in participants with hormone receptor positive (HR+) breast cancer. Part 3 will evaluate STX-478 as combination therapy with endocrine therapy (aromatase inhibitors, fulvestrant, tamoxifen, or imlunestrant) and a CDK4/6 Inhibitor (either Ribociclib, Palbociclib or Abemaciclib) in participants with HR+ breast cancer.

Each study part will include a 28-day screening period, followed by treatment with STX-478 monotherapy or combination therapy.
