NCT06545331

Study of XB010 in Subjects With Solid Tumors

This is a FIH study is to evaluate the safety, tolerability, PK, immunogenicity, and preliminary antitumor activity of XB010 as a single agent and in combination with pembrolizumab in subjects with locally advanced or metastatic solid tumors for whom alternative therapies do not exist or available therapies are intolerable or no longer effective.

BGB-43395 Alone or as Part of Combination Therapies in Participants With Breast Cancer and Other Advanced Solid Tumors

This is a dose escalation and dose expansion study to compare how well BGB-43395, a selective cyclin-dependent kinase 4 (CDK4) inhibitor, works as monotherapy or in combination with fulvestrant, letrozole, or elacestrant in participants with hormone receptor positive (HR+) and human epidermal growth factor 2 negative (HER2-) breast cancer (BC) and other advanced solid tumors. The main purpose of this study is to explore the recommended dosing for BGB-43395.

A Study to Examine the Safety of Different Doses of BG-68501 Given to Participants With Advanced-Stage Tumors

This study is a first-in-human (FIH), Phase 1a/1b study of BG-68501, a cyclin-dependent kinase-2 inhibitor (CDK2i), to assess the safety, tolerability, pharmacokinetics (PK), pharmacodynamics, and preliminary antitumor activity of BG-68501 in participants with advanced, nonresectable, or metastatic solid tumors as monotherapy and in combination with fulvestrant with or without BGB-43395, a selective CDK4 inhibitor, in adults with hormone receptor positive (HR+)/human epidermal growth factor receptor 2 negative (HER2-) breast cancer (BC). The study will also identify a recommended dose for expansion (RDFE) for BG-68501 as monotherapy and in combination for subsequent disease directed studies. The study will be conducted in 2 parts: Part 1 (dose escalation and safety expansion, including evaluation of food effect) and Part 2 (dose expansion).

ARX788 for Treating Patients With HER2-low Locally Advanced Unresectable or Metastatic Breast Cancer

This phase II trial tests how well ARX788 works in treating patients diagnosed with HER2-low, locally advanced unresectable or metastatic breast cancer. ARX788 is an antibody-drug conjugate (ADC) that is given by infusion (diluted and injected slowly into veins). Antibodies are proteins which are naturally produced by the body's immune system to help fight infections. ARX788 consists of antibodies that have been attached to a toxin that has the potential to kill cancer cells. ARX788 sticks to a protein called human epidermal growth factor receptor (HER2), which is found on some breast cancer cells. Giving ARX788 may be safe and effective in treating patients with HER2-low locally advanced unresectable metastatic breast cancer.

Sequencing Antibody Drug Conjugates in ER+/HER2 LOW/ULTRA LOW MBC

The purpose of this research study is to see if the medication sacituzumab govitecan (SG) is effective at the currently approved dose and schedule in people who have previously received trastuzumab deruxtecan (T-DXd) for the treatment of metastatic, hormone receptor positive (HR+)/human epidermal growth factor 2 low (HER2 low) breast cancer. Although SG is approved to treat metastatic HR+/HER2 negative breast cancer, the aim of this study is to determine if SG is still effective specifically in people who have already received T-DXd.
