The purpose of this study is to find out whether the study drug, LY3537982, is safe and
effective in cancer patients who have a specific genetic mutation (KRAS G12C). Patients must
have already received or were not able to tolerate the standard of care, except for specific
groups who have not had cancer treatment. The study will last up to approximately 4 years.

This phase II trial tests the safety, side effects, best dose and activity of tovorafenib (DAY101) in treating patients with Langerhans cell histiocytosis that is growing, spreading, or getting worse (progressive), has come back (relapsed) after previous treatment, or does not respond to therapy (refractory). Langerhans cell histiocytosis is a type of disease that occurs when the body makes too many immature Langerhans cells (a type of white blood cell). When these cells build up, they can form tumors in certain tissues and organs including bones, skin, lungs and pituitary gland and can damage them. This tumor is more common in children and young adults. DAY101 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Using DAY101 may be effective in treating patients with relapsed or refractory Langerhans cell histiocytosis.

This phase II trial tests how well nivolumab and ipilimumab immunotherapy with or without cabozantinib in treating patients with nasopharyngeal cancer that has come back (after a period of improvement) (recurrent), has spread from where it first started (primary site) to other places in the body (metastatic), or for which no treatment is currently available (incurable). Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Cabozantinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of cancer cells. Giving immunotherapy with nivolumab and ipilimumab and targeted therapy with cabozantinib may help shrink and stabilize nasopharyngeal cancer.

This phase II trial studies the effect of lutetium Lu 177 dotatate compared to the usual treatment (everolimus) in treating patients with somatostatin receptor positive bronchial neuroendocrine tumors that have spread to other places in the body (advanced). Radioactive drugs, such as lutetium Lu 177 dotatate, may carry radiation directly to tumor cells and may reduce harm to normal cells. Lutetium Lu 177 dotatate may be more effective than everolimus in shrinking or stabilizing advanced bronchial neuroendocrine tumors.

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 study is being done to find out if tucatinib with other cancer drugs works better than
standard of care to treat participants with HER2 positive colorectal cancer. 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 in this study have colorectal cancer that has spread through the body
(metastatic) and/or cannot be removed with surgery (unresectable).

Participants will be assigned randomly to the tucatinib group or standard of care group. The
tucatinib group will get tucatinib, trastuzumab, and mFOLFOX6. The standard of care group
will get either:

- mFOLFOX6 alone,

- mFOLFOX6 with bevacizumab, or

- mFOLFOX6 with cetuximab mFOLFOX6 is a combination of multiple drugs. All of the drugs
given in this study are used to treat this type of cancer.
