This clinical trial is evaluating a drug called ART0380 in participants with advanced or metastatic solid tumors. The main goals of this study are to:

* Find the recommended dose of ART0380 that can be given safely to participants alone and in combination with gemcitabine or irinotecan
* Learn more about the side effects of ART0380 alone and in combination with gemcitabine or irinotecan
* Learn more about the effectiveness of ART0380 alone and in combination with gemcitabine or irinotecan

Immunoglobulin light chain (AL) amyloidosis is the most common form of systemic amyloidosis. AL amyloidosis has many root causes and is characterized by the overproduction of AL that are secreted by clonal bone marrow plasma cells. This is a study to determine adverse events and change in disease activity in adult participants with AL amyloidosis treated with ABBV-383.

Etentamig (ABBV-383) is an investigational drug being developed for the treatment of AL amyloidosis. This study in broken into 2 parts (dose escalation and dose expansion) with 4 arms. During dose escalation (arms 1-3) participants will receive 1 of 3 doses of ABBV-383 to determine the part 2 dose. After completion of the dose escalation portion of the study, the dose expansion (part 2) portion of the study will begin. One arm (arm 4) will begin and participants will receive a dose determined during the dose escalation portion (part 1). Around 76 adult participants with relapsed/refractory AL amyloidosis will be enrolled at approximately 25 sites across the world.

Participants will receive Etentamig (ABBV-383) as an infusion into the vein for up to approximately 2 year study duration.

There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and questionnaires.

The main purpose of this study is to find out whether the study drug, LY4050784, is safe, tolerable and effective in participants alone or in combination with other anticancer agents. In addition, with locally advanced or metastatic solid tumors with a BRG1 (Brahma-related gene 1, also known as SMARCA4) alteration who have previously received, do not qualify for, or are refusing standard of care treatments, or there is no standard therapy available for the disease. The study is conducted in two parts - phase Ia (dose-escalation) and phase Ib (dose-optimization, dose-expansion). The study will last up to approximately 4 years.

This phase I/II trial studies the side effects and best dose of temozolomide and M1774 and how well they works in treating patients with cancer that has spread from where it first started (primary site) to other places in the body (metastatic) and may have spread to nearby tissue, lymph nodes, or distant parts of the body (advanced). Temozolomide is in a class of medications called alkylating agents. It works by damaging the cell's deoxyribonucleic acid (DNA) and may kill tumor cells and slow down or stop tumor growth. M1774 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Adding M1774 to temozolomide may shrink or stabilize cancer for longer than temozolomide alone.

This is a Phase 1/1b open-label, multi-center dose escalation and dose optimization study designed to evaluate the safety and preliminary efficacy of IAM1363 in participants with advanced cancers that harbor HER2 alterations.

This phase II ADC MATCH screening and multi-sub-study treatment trial is evaluating whether biomarker-directed treatment with one of three antibody-drug conjugates (ADCs) (sacituzumab govitecan, enfortumab vedotin, and trastuzumab deruxtecan) works in treating patients with solid tumor cancers that have high expression of the Trop-2, nectin-4, or HER2 proteins and that may have spread from where they first started (primary site) to nearby tissue, lymph nodes, or distant parts of the body (advanced) or to other places in the body (metastatic). Precision medicine is a form of medicine that uses information about a person's genes, proteins, and environment to prevent, diagnose, or treat disease in a way that is tailored to the patient. ADCs such as sacituzumab govitecan, enfortumab vedotin, and trastuzumab deruxtecan are monoclonal antibodies attached to biologically active drugs and are a form of targeted therapy. Sacituzumab govitecan is a monoclonal antibody, called sacituzumab, linked to a drug called govitecan. Sacituzumab attaches to a protein called Trop-2 on the surface of tumor cells and delivers govitecan to kill them. Enfortumab vedotin is a monoclonal antibody, enfortumab, linked to an anticancer drug called vedotin. It works by helping the immune system to slow or stop the growth of tumor cells. Enfortumab attaches to a protein called nectin-4 on tumor cells in a targeted way and delivers vedotin to kill them. Trastuzumab deruxtecan is composed of a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug, called deruxtecan. Trastuzumab attaches to HER2 positive tumor cells in a targeted way and delivers deruxtecan to kill them. Personalized treatment with sacituzumab govitecan, enfortumab vedotin, or trastuzumab deruxtecan may be an effective treatment option for patients with advanced or metastatic solid tumors that screen positive for high expression of Trop-2, nectin-4, or HER2, respectively.

Imaging will be exploratory and be used intraoperatively. There have been no discovered risks associated with the device to be used in this study, and none are anticipated given the diagnostic and non-invasive, 'ex vivo' nature of device use. Of note, the surgical resection will proceed as per standard of care and will not be affected by the research protocol.

Potential Benefit: Imaging intra-operatively will ensure surgeons to identify at risk resection margins.

Time Commitment: There are no additional visits that will be asked of you to partake in this study.

Drug is FDA approved and Exposure to Radiation is minimal.

Immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment and work by blocking protein interactions that normally prevent the immune system from recognizing and destroying cancer cells. However, these agents, now approved for over 15 types of cancers and for both early-stage and metastatic disease, are capable of causing inflammation in any organ system of the body that can lead to organ damage, dysfunction, and even death in rare cases. Some patients may suffer acute and treatable complications like joint pain, but some may have irreversible complications like hypothyroidism that requires daily, life-long medication. It is therefore important to fully understand the different types of damage ICIs can cause to better monitor patients receiving ICI therapy.

A rising concern from recent reports in the literature is that ICIs may weaken bone and increase the risk of fractures. In this study, the investigators aim to characterize how ICIs impact the bone by examining several factors in patients undergoing curative-intent ICI treatment either alone or in combination with chemotherapy: bone mineral density, bone volume, and markers of bone turnover in the blood. The study will use two imaging techniques to assess bone mineral density and volume. DXA (dual X-ray absorptiometry) imaging uses low-dose X-rays to measure how dense (or strong) bones are and is often used to diagnose or assess the risk of osteoporosis. High-resolution peripheral quantitative computed tomography (HRpQCT) is a 3D imaging technology that can quantify bone structure and volume and offers high resolution that can be used to assess bone in smaller bones of the peripheral skeleton.

The investigators hypothesize that ICI treatment will weaken bones and increase the risk of fractures. As ICI therapy is relatively new, a rising number of patients may be at risk of fractures or have low bone density that is not being monitored because there are no guidelines in place notifying physicians of this potential risk to patients. This is study will provide important preliminary data that will be the basis for larger studies in the future aiming to better monitor and potentially treat bone weakening in patients treated with ICIs to reduce the pain, inconvenience, and complications from fragility fractures.

This first-in-human study will be counducted to evaluate the safety, tolerability, pharmacokinetics (PK) and anti-tumor activity of YH32367 in Patients with HER2-Positive Locally Advanced or Metastatic Solid Tumors.

This study will apply novel MRI approaches with established sensitivity to tissue oxygen consumption and perfusion to predict hypoxia-associated radiation resistance, manifested as tumor recurrence and progression post-treatment.
