Duarte, CaliforniaAges 18 years+ - NCT06824363RecruitingEarly Phase 1
Intra-tumor injection study for stomach and esophagus cancer with ARID1a mutation
This trial tests a new approach where immune cells are injected directly into the tumor in people with a specific genetic change (ARID1a mutation) in their stomach or esophagus cancer. It aims to see if this treatment can help when used before any other cancer therapy.
Orange, CaliforniaAges 18 years+ - NCT05732831RecruitingPhase 1/Phase 2
Study drug for tumors with MTAP loss
This Phase 1/2 trial tests TNG462 (with or without pembrolizumab, depending on the plan) in solid tumors that have lost MTAP. The goal is to check safety and learn whether the treatment can help people with these specific tumor changes.
Palo Alto, CaliforniaAges 18 years+ - NCT05768139RecruitingPhase 1/Phase 2
Testing a new targeted drug for advanced solid tumors with PI3Kα mutation
This trial tests tersolisib, a new targeted medicine, in adults with advanced or hard-to-remove solid cancers. It focuses on tumors that have a specific genetic change (PI3Kα mutation) to see how well the treatment works and what side effects it causes.
Los Angeles, CaliforniaAges 18 years+ - NCT05786924RecruitingPhase 1/Phase 2
Targeted cancer drug study for RAS/RAF mutation-positive tumors
This Phase 1/2 study tests S241656 (a targeted cancer medicine) in people whose cancers have certain “RAS/RAF” gene changes. It may help shrink tumors or control cancer growth, and also finds the safest dose and best way to use the drug.
San Francisco, CaliforniaAges 18 years+ - NCT06431594RecruitingPhase 1
Study of a new drug for advanced solid tumors
This trial tests a new drug called Mocertatug Rezetecan for people with advanced solid tumors that have stopped responding to standard treatments. It targets a protein called B7-H4 on cancer cells to try to slow or shrink the tumor.
Fountain Valley, CaliforniaAges 18 years+ - NCT06667141RecruitingPhase 1
Study of ACR-2316 for advanced solid tumors
This study tests a new targeted drug called ACR-2316 for people with specific advanced solid tumors that have already been treated but are no longer responding. It aims to see how well the drug works and how safe it is, while looking for a tumor that has certain markers (like a protein or genetic change) that may make the drug more effective.
Newport Beach, CaliforniaAges 18 years+ - NCT05176483RecruitingPhase 1
New drug combinations for advanced solid tumors
This trial tests a new drug called zanzalintinib, which may slow or shrink various types of advanced cancer. It is given together with other cancer treatments, and the study is looking at many different cancers including kidney, prostate, bladder, lung, liver, and more.
Palo Alto, CaliforniaAges 18 years+ - NCT04665739RecruitingPhase 2
Lutetium Lu-177 for lung carcinoid tumors with somatostatin receptors
This trial tests lutetium Lu 177 dotatate, a targeted radiation treatment, for advanced lung neuroendocrine (carcinoid) tumors that have a specific marker called somatostatin receptors. It may help shrink tumors by delivering radiation directly to cancer cells that “light up” on a special scan.
Beverly Hills, CaliforniaAges 18 years+ - NCT06425926RecruitingPhase 1/Phase 2
Study of GIM-531 in advanced solid tumors
This study tests a new oral drug, GIM-531, alone and in combination with an anti-PD-1 therapy for people with advanced solid tumors that have stopped responding to standard treatments. The goal is to see if it is safe and effective.

First drug test for metastatic uveal melanoma with specific gene changes
This Phase 1/2 trial studies IDE196 in adults with metastatic uveal melanoma that has certain gene mutations or fusions. It’s mainly testing safety and correct dosing, and may help shrink tumors in patients matched to the tumor’s genetic changes.
Los Angeles, CaliforniaAges 18 years+ - NCT04142437Recruiting
Tracking how larotrectinib works for NTRK fusion cancers in routine care
This study follows people with cancers that have an NTRK gene fusion to learn how safe and effective larotrectinib is during everyday treatment. It may help confirm whether this medicine works well in real-world patients and side effects stay manageable.
Los Angeles, CaliforniaAges Any age - NCT06771219RecruitingPhase 1
Testing SLV-154 for advanced cancers
This trial tests a new drug called SLV-154 for people whose advanced cancer has not responded to standard treatments. The goal is to see if SLV-154 can shrink tumors or slow cancer growth.

What taking part in a metastatic solid tumor study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
