The purpose of this study is to compare the efficacy of zanidatamab plus chemotherapy versus trastuzumab plus chemotherapy.

NRG-CC015 is a prospective, randomized phase III clinical trial to evaluate the efficacy of two distinct digital approaches for delivering a mindfulness-based intervention: a live, instructor-led version delivered over Zoom (MAPs LO), and an app-based, self-paced version (MAPs App). Participants will include younger breast cancer survivors (BCS) who were diagnosed with breast cancer at or before age 50 years, have completed their primary cancer treatment (i.e., surgery, radiation, and/or chemotherapy) at least 6 months earlier, and report elevated depressive symptoms.

The purpose of this study is to evaluate evorpacept with anti-cancer therapies in advanced/metastatic malignancies. The study is comprised of the following substudies:

* Metastatic HER2+ breast cancer (MBC) - single-arm substudy evaluating the efficacy, safety, and tolerability of evorpacept in combination with trastuzumab and chemotherapy in participants with HER2-positive metastatic breast cancer who have previously received trastuzumab-deruxtecan. This substudy is actively recruiting.
* Metastatic colorectal cancer (CRC) - dose escalation phase to evaluate evorpacept in combination with other drugs. This substudy is not recruiting.
* Recurrent/metastatic head and neck cancer (HNSCC) - dose escalation phase to evaluate evorpacept in combination with other drugs. This substudy is not recruiting.

The purpose of this study is to determine if tucatinib works better than placebo when given with other drugs to treat participants with HER2-positive breast cancer. A placebo is a pill that looks the same as tucatinib but has no medicine in it. This study will also test what side effects happen when participants take this combination of drugs. A side effect is anything a drug does to the body besides treating your disease. Participants will have cancer that has spread in the body near where it started (locally advanced) and cannot be removed (unresectable) or has spread through the body (metastatic). In this study, all participants will get either tucatinib or placebo. Participants will be assigned randomly to a group. This is a blinded study, so patients and their doctors will not know which group a participant is in. All participants will also get trastuzumab and pertuzumab. These are 2 drugs used to treat this type of cancer.

This research trial studies genetic profiles in blood and tumor samples from patients with estrogen receptor positive and HER2 negative breast cancer that has spread to other places in the body who are receiving palbociclib and endocrine therapy. Examine the genetic changes associated with the cancer and comparing the genetic material from the cancer tissue with the genetic material found in the blood may help doctors to develop customized treatment for breast cancer.
