Recruiting studies in California
- NCT04291755Recruiting
Stool bank for people receiving cancer immunotherapy
This study is building a “stool bank,” meaning they collect and store stool samples from people who are getting cancer immunotherapy. Researchers plan to analyze these samples to better understand cancer and treatment—your participation may help future research.
Fountain Valley, CaliforniaAges 18 years+ - NCT04302025RecruitingPhase 2
Testing targeted and immunotherapy before lung cancer surgery
This trial studies whether giving different cancer medicines before (and sometimes after) surgery improves outcomes for people with early-stage, operable lung cancer that has certain tumor markers. It may help by trying to shrink or control the cancer early and lower the chance it comes back.
Duarte, CaliforniaAges 18 years+ - NCT04410796RecruitingPhase 2
Osimertinib alone or with chemo for EGFR-mutant lung cancer
This trial tests whether osimertinib alone is as good as osimertinib plus chemotherapy for lung cancers that have a specific EGFR mutation. It may help by improving how well the cancer responds and slows growth in people with metastatic non-small cell lung cancer.
Sacramento, CaliforniaAges 18 years+ - NCT04429542RecruitingPhase 1
Test of an EGFR-targeting drug for advanced solid cancers
This Phase 1 study tests the safety of BCA101 (an EGFR-targeting treatment) alone or combined with pembrolizumab. It may help people with certain EGFR-driven advanced cancers, depending on the tumor type, prior treatments, and required biopsy testing.
La Jolla, CaliforniaAges 18 years+ - NCT04486833RecruitingPhase 1/Phase 2
Genetic-targeted drug plus gene medicine for EGFR lung cancer
This trial studies a gene-based treatment added to osimertinib (a targeted lung cancer pill) for advanced EGFR-mutant lung cancer that has started growing again on osimertinib. It may help by attacking the cancer with both its usual target treatment and an added genetic approach.
Los Angeles, CaliforniaAges 18 years+ - NCT04510129Recruiting

Irvine, CaliforniaAges 12 years+ - NCT04606446RecruitingPhase 2
Study drug for ER-positive, HER2-negative cancers after treatment
This Phase 2 study tests a new Pfizer medicine (PF-07248144) for certain advanced or metastatic breast, prostate, or lung cancers that have not responded to standard treatment or no standard options exist. You may qualify if you have a specific tumor type and a limited number of prior cancer treatments, and if your body functions (blood, liver, kidneys) and heart rhythm meet safety limits.
San Francisco, CaliforniaAges 18 years+ - NCT04686305RecruitingPhase 1
Test drug T-DXd plus immunotherapy, with or without chemotherapy for HER2+ lung cancer
This Phase 1 study tests the safety (and early effectiveness) of T-DXd combined with immunotherapy, sometimes also with chemotherapy, in people with advanced lung cancer that is HER2-positive. It may help if standard options have been limited or your tumor does not have certain genetic changes that already have targeted treatments.
Orange, CaliforniaAges 18 years+ - NCT04895709RecruitingPhase 1/Phase 2
Testing a new cancer drug for advanced solid tumors
This early-phase trial tests how well a new drug (BMS-986340) works alone and combined with other treatments in people with advanced solid tumors that have progressed despite standard care. It also studies tumor samples to look for biomarkers that may predict who benefits.
Clovis, CaliforniaAges 18 years+ - NCT05877599RecruitingPhase 1
Study of a new treatment for advanced cancers with a specific gene change
This trial tests a new type of therapy (NT-175) for people with certain advanced cancers that have a specific genetic change. It might help if your tumor has the TP53 R175H mutation and you have the HLA-A*02:01 immune marker.
Duarte, CaliforniaAges 18 years+ - NCT06726148RecruitingPhase 1/Phase 2
Study of ECI830 for advanced breast cancer and solid tumors
This trial is testing a new drug called ECI830, either alone or with another drug, for people with advanced breast cancer or other solid tumors that have not responded to standard treatments. It may be an option if you have HR+/HER2- breast cancer, small cell lung cancer, or a tumor with a specific gene change (CCNE1 amplification).
Los Angeles, CaliforniaAges 18–100 - NCT04969315RecruitingPhase 1/Phase 2
Drug TT-10 and TT-4 for advanced solid tumors
This early-phase trial tests two investigational drugs—TT-10 and TT-4—alone and together in people with advanced solid cancers. The study is designed to find safe doses and see if the treatment can shrink tumors or slow cancer growth.
Los Angeles, CaliforniaAges 18 years+ - NCT04981119Recruiting
Test apheresis for CAR T manufacturing in HLA-A2 solid tumors
This trial studies how a process called apheresis is used to make CAR T cells for people with certain solid tumors. It is designed for tumors that have lost a specific immune marker (HLA-A*02), which may affect how well CAR T therapies work.
Santa Monica, CaliforniaAges 18 years+ - NCT05005403RecruitingPhase 1
Testing azirkitug for lung, head/neck, and other solid cancers
This Phase 1 study tests how a new medicine (azirkitug) behaves in the body and how safe it is, given by IV infusion alone or with other cancer drugs. It may help people with several advanced solid tumor cancers, especially after standard treatments have stopped working.
Duarte, CaliforniaAges 18 years+ - NCT05059444Recruiting

What taking part in a small cell lung cancer 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.
