This phase II trial studies how well TPIV100 and sargramostim work in treating patients with HER2 positive, stage I-III breast cancer that has residual disease after chemotherapy prior to surgery. It also studies why some HER2 positive breast cancer patients respond better to chemotherapy in combination with trastuzumab and pertuzumab. TPIV100 is a type of vaccine made from HER2 peptide that may help the body build an effective immune response to kill tumor cells that express HER2. Sargramostim increases the number of white blood cells in the body following chemotherapy for certain types of cancer and is used to alert the immune system. It is not yet known if TPIV100 and sargramostim will work better in treating patients with HER2 positive, stage I-III breast cancer.

This study aims to determine the safety, pharmacokinetics (PK) and recommended Phase 3 dose
(RP3D) of RYZ101 in Part 1, and the safety, efficacy, and PK of RYZ101 compared with
investigator-selected standard of care (SoC) therapy in Part 2 in subjects with inoperable,
advanced, well-differentiated, somatostatin receptor expressing (SSTR+)
gastroenteropancreatic neuroendocrine tumors (GEP-NETs) that have progressed following
treatment with Lutetium 177-labelled somatostatin analogue (177Lu-SSA) therapy, such as
177Lu-DOTATATE or 177Lu-DOTATOC (177Lu-DOTATATE/TOC), or 177Lu-high affinity [HA]-DOTATATE.

This phase II ComboMATCH treatment trial tests how well AMG 510 (sotorasib) with or without panitumumab works in treating patients with KRAS G12C mutant solid tumors that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Sotorasib is in a class of medications called KRAS inhibitors. It works by blocking the action of the abnormal protein that signals cancer cells to multiply. This helps stop or slow the spread of cancer cells. Panitumumab is in a class of medications called monoclonal antibodies. It works by slowing or stopping the growth of cancer cells. Giving combination panitumumab and sotorasib may kill more tumor cells in patients with advanced solid tumors with KRAS G12C mutation.

This phase III trial compares the addition of total ablative therapy to the usual systemic therapy versus the usual systemic therapy alone in treating patients with advanced colorectal cancer that has spread to up to 4 body sites (limited metastatic). The usual approach for patients who are not participating in a study is treatment with intravenous (through a vein) and/or oral medications (systemic therapy) to help stop the cancer sites from getting larger and the spread of the cancer to additional body sites. The ablative local therapy will consist of very focused, intensive radiotherapy called stereotactic ablative radiotherapy (SABR) with or without surgical resection and/or microwave ablation, which is a procedure where a needle is temporarily inserted in the tumor and heat is used to destroy the cancer cells. The addition of ablative local therapy to the usual approach of systemic therapy could be more effective than usual chemotherapy alone by increasing the life of patients with limited metastatic colorectal cancer.
