This study is for patients who have cancer and are experiencing loss of weight and appetite. The study wants to find out if this taking olanzapine for four weeks will increase your appetite as compared to megestrol acetate. The study is looking to see if that approach is better or worse than the usual approach for your loss of appetite and weight. The usual approach is defined as care most people get for loss of appetite.

This research study is enrolling participants that have been diagnosed with advanced gastric cancer (a disease in which cancer cells form in the lining of the stomach) or gastroesophageal junction cancer (a type of cancer forming in the area where the tube that connects the mouth and the stomach join together) and have not received prior treatment for advanced cancer and the tumor has already tested positive for fibroblast growth factor receptor 2b (FGFR2b) expression. FGFR2b is a protein that possibly causes cells to grow more quickly and multiply abnormally. The purpose of this study is to see if bemarituzumab is safe, tolerable, and effective when administered along with mFOLFOX6 (a combination of 5 fluorouracil [5 FU], oxaliplatin and leucovorin) and nivolumab and whether it causes any side effects. Bemarituzumab is not approved by the Food and Drug Administration (FDA). Participants will be pre-screening to see if they qualify to participate in Part 2. During the pre-screening portion, participants will provide either archived tissue or a fresh tumor sample in order to test for FGFR2b proteins. If the test results show an excessive amount of FGFR2b proteins in the tumor, participants may be asked to consider participating in the Part 2 study involving bemarituzumab, an investigational drug for people with advanced gastric or gastroesophageal junction cancer. Participants in this study will receive either bemarituzumab with mFOLFOX6 and nivolumab or placebo with mFOLFOX6 and nivolumab. The placebo will look like bemarituzumab but it will not contain active ingredients and has no effect on participants' condition. This study involves pharmacokinetic testing which is a blood test to determine how much study drug is in the blood. Bemarituzumab is not approved by the Food and Drug Administration (FDA). Participants could be in this study for up to 40 months and up to 57 visits.

This study is for patients with invasive cancer I-IV and be scheduled to receive anti-PD-1/-L1 ICI-containing therapy. This study is being done to see if we can understand which patients will develop side effects from immune checkpoint inhibitors, and what kind of side effects they will get and can we predict long-term treatment outcomes after immune checkpoint inhibitor treatment, like which patients will have a cancer that shrinks or disappears.

This study is for patients with cancer in the stomach, esophagus, or gastroesophogeal junction. The study is being done to see if by adding a third chemotherapy drug to the usual combination of two chemotherapy drugs is better or worse than the usual approach for treatment.

The purpose of this study is to evaluate investigational treatments (study drug) for unresectable metastatic colorectal cancer to determine if any of these study treatments improve overall survival as compared to standard treatments. The goal is to determine the optimal dose level, safety, and tolerability for the study drug ABBV-400 in combination with fluorouracil, folinic acid, and bevacizumab. The study consists of two stages, Stage 1 - Safety Lead-In Dose Escalation and Stage 2- Dose Optimization. ABBV-400 is not FDA approved. Bevacizumab is FDA approved by the U.S. Food and Drug Administration (FDA) to treat various cancers but may not be approved for your type of cancer. Treatment for this study may be up to 3 years. The procedures include blood and urine samples, questionnaires, infusions, and CT scans. Risks include diarrhea, nausea, vomiting, fatigue, and numbness, tingling, or weakness in arms and legs. You may or may not receive a direct benefit from participating in this trial, however, information learned from the trial may help other people in the future.

The purpose of this study is to evaluate investigational treatments (study drugs) for metastatic esophageal carcinoma to determine if any of these study drugs improve overall survival as compared to standard treatments. The study drugs used in this trial are lenvatinib (E7080/MK‑7902), also called LENVIMA, and pembrolizumab (MK‑3475), also called KEYTRUDA or pembro. Both lenvatinib and pembrolizumab have been approved by the U.S. Food and Drug Administration (FDA) to treat various cancers but may not be approved for your type of cancer. Treatment for this study may be up to 3 years. The procedures include blood and urine samples, questionnaires, infusions, and CT scans. Risks include itchy skin, loose stools, cough, and joint pain. You may or may not receive a direct benefit from participating in this trial, however, information learned from the trial may help other people in the future.

A clinical research study is an investigation in humans of a potential medical treatment that is designed to discover or verify whether it works and is safe. This study will test an investigational drug called DF9001. "Investigational" means that it has not been approved by any health authority such as the United States Food and Drug Administration (FDA) or the European Medicines Agency (EMA). Information gathered from this study will be sent to the various health authorities.
The study has two parts: a Dose Escalation part and an Efficacy Expansion part. The main purpose of the Efficacy Expansion part of this study is to test whether the study drug (DF9001) works (if it causes cancer to shrink or disappear). The Dose Escalation part of this study's main purpose is to test different doses of the study drug by itself, and also in combination with a drug called nivolumab, an FDA approved drug. Some foreseeable risks associated with DF9001 include Diarrhea,
Skin problems, Nail changes, Eye problems, Inflammation of the lungs, intestines and liver, as well as unforeseen side effects that may occur. There is no direct benefit in participating in this study.

The purpose of this study is to evaluate ABBV-400 in subjects with select solid tumors. This study will consist of
multiple cohorts with each cohort investigating ABBV-400 at 3 mg/kg Q3W.
The study will consist of a Screening, a Treatment, and a Follow-Up period.
All screening procedures must be performed within 28 days of first dose with the exception of tumor
tissue biopsy, which may occur during screening or any time after disease progression on the most
recent treatment. Subjects will continue treatment with ABBV-400 3 mg/kg Q3W until documented disease progression,
intolerable toxicity, or the subject meets other protocol criteria for discontinuation of treatment
(whichever occurs first). The maximum treatment duration will be 2 years.

The purpose of this study is to evaluate investigational treatments (study drug) for pancreatic adenocarcinoma following surgery in order to determine if any of these study treatments improve overall survival as compared to standard treatments. The goal is to determine the optimal dose level, safety, and tolerability for the study drug BNT321 in combination with mFOLFIRINOX. BNT321 is not FDA approved. mFOLFIRINOX is FDA approved by the U.S. Food and Drug Administration (FDA) to treat various cancers but may not be approved for your type of cancer. Treatment for this study may be up to 3 years. The procedures include blood and urine samples, questionnaires, infusions, and CT scans. Risks include diarrhea, nausea, vomiting, fatigue, headache, fever, and joint pain. You may or may not receive a direct benefit from participating in this trial, however, information learned from the trial may help other people in the future.
