Recruiting studies in California
- NCT06671613Recruiting
Fasting-mimicking diet with immunotherapy for advanced lung cancer
This study combines a special periodic diet that mimics fasting with the standard immunotherapy drug pembrolizumab (Keytruda) for people with advanced non-small cell lung cancer. The goal is to see if the diet can help the immunotherapy work better.
Long Beach, CaliforniaAges 18 years+ - NCT06745908RecruitingPhase 3
New drug combo for lung cancer after immunotherapy stops working
This trial tests a new drug combination (N-803 and tislelizumab with chemotherapy) for people whose lung cancer stopped responding to standard immunotherapy. The goal is to see if this treatment can help shrink tumors or slow the cancer's growth.
El Segundo, CaliforniaAges 18–90 - NCT06096844RecruitingPhase 3
Chemo plus immunotherapy vs immunotherapy alone for older adults with advanced lung cancer
This trial compares chemotherapy combined with immunotherapy to immunotherapy alone for adults 70 and older with advanced non-small cell lung cancer that has a specific protein level (PD-L1 1-49%). It aims to find which treatment works better for this group.
Dublin, CaliforniaAges 70 years+ - NCT07288034RecruitingPhase 2
Immunotherapy biomarkers for advanced lung cancer
This study looks at blood and tissue biomarkers to predict how well immunotherapy (with or without chemotherapy) works for advanced non-small cell lung cancer. It also helps decide the best second treatment if the first one stops working.
Lancaster, CaliforniaAges 18 years+ - NCT05361174RecruitingPhase 1/Phase 2
Testing an IOV-4001 infusion for advanced melanoma or lung cancer
This trial studies how well and how safely an infusion called IOV-4001 works in adults with advanced melanoma or non-small-cell lung cancer that cannot be removed with surgery. It also aims to see what side effects occur and whether the treatment can help control the cancer.
Los Angeles, CaliforniaAges 18–70 - NCT06500481RecruitingPhase 3
Proton vs standard radiation for cancer spread to brain/spine lining
This trial compares a newer type of radiation (proton therapy) to standard radiation for people whose breast or lung cancer has spread to the lining of the brain and spinal cord. It aims to see if proton therapy can better control the disease while causing fewer side effects.
San Diego, CaliforniaAges 18 years+ - NCT06518057RecruitingPhase 2
Sparing memory during brain radiation for leptomeningeal metastases
This trial tests a special type of radiation that avoids the memory center of the brain (the hippocampus) while treating cancer that has spread to the lining of the brain and spinal cord. It may help reduce side effects on thinking and memory for people with breast or lung cancer.
San Francisco, CaliforniaAges 18 years+ - NCT05920356RecruitingPhase 3
Tested KRAS-targeted sotorasib plus chemo vs pembrolizumab plus chemo
This Phase 3 trial tests whether sotorasib plus standard chemotherapy works better than pembrolizumab (an immunotherapy) plus standard chemotherapy as first treatment for certain advanced lung cancers. It may help people whose tumors have a KRAS G12C mutation and that do not show PD-L1 on testing.
Santa Barbara, CaliforniaAges 18–100 - NCT06538038Recruiting
Osimertinib plus chemo vs. osimertinib alone for EGFR-mutated NSCLC
This study compares two standard treatments for advanced lung cancer with an EGFR mutation: osimertinib alone versus osimertinib plus chemotherapy. It aims to see which approach works better and is not a trial of a new drug, so you can receive usual care while contributing data.
San Jose, CaliforniaAges 18 years+ - NCT04165070RecruitingPhase 1/Phase 2
Stage IV lung cancer trial using pembrolizumab with or without chemotherapy
This Phase 1/2 study tests pembrolizumab (an immune-based cancer treatment) either alone or with chemotherapy in people newly diagnosed with stage IV non-small cell lung cancer (NSCLC). It looks at how well the treatments work and whether they are safe, especially in people who haven’t had treatment yet for metastatic disease.
Duarte, CaliforniaAges 18 years+ - NCT06225427RecruitingPhase 1
Gilteritinib for advanced ALK-positive lung cancer
This trial tests a drug called gilteritinib for people with a specific genetic type of lung cancer (ALK-positive) that has spread and has been treated before. You may be eligible if you have already tried at least one targeted therapy, and your cancer is still growing.
Los Angeles, CaliforniaAges 18 years+ - NCT06162221RecruitingPhase 1/Phase 2
Study of RAS inhibitors for advanced RAS-mutated lung cancer
This trial tests new drugs that target specific RAS mutations in advanced non-small cell lung cancer. It's for people whose cancer has a KRAS G12C, G12D, or other RAS mutation and who have already tried standard treatments.
Irvine, CaliforniaAges 18 years+ - NCT04181060RecruitingPhase 3
Osimertinib alone or with bevacizumab for EGFR-mutant lung cancer
This Phase 3 trial tests whether starting osimertinib with or without bevacizumab helps people with advanced EGFR-mutant lung cancer live longer and control the cancer better. Your EGFR mutation test result and past treatments are key to whether you can join.
Antioch, CaliforniaAges 18 years+ - NCT06249282RecruitingPhase 1
Carfilzomib and sotorasib for KRAS G12C lung cancer
This trial tests a combination of two drugs: carfilzomib and sotorasib, for people with a specific type of advanced lung cancer (KRAS G12C mutation) who have already tried a KRAS-targeting drug that stopped working. The goal is to see if this new combination can shrink tumors or slow the cancer.
Irvine, CaliforniaAges 18 years+ - NCT07012031RecruitingPhase 1/Phase 2
Sotorasib and trastuzumab deruxtecan for KRAS G12C lung cancer
This trial tests a combination of two drugs, sotorasib and trastuzumab deruxtecan, for people with advanced or metastatic non-small cell lung cancer that has a KRAS G12C mutation. It may be an option if you've already had treatment with a KRAS G12C inhibitor, immunotherapy, and chemotherapy.
Sacramento, CaliforniaAges 18 years+ - NCT07250477RecruitingPhase 2
Guided immunotherapy for advanced lung cancer

Sacramento, CaliforniaAges 18 years+ - NCT07154706RecruitingPhase 3
Taletrectinib vs placebo after surgery for ROS1-positive lung cancer
This trial tests whether taletrectinib (a targeted pill) can help prevent lung cancer from coming back after surgery in people whose tumors have a ROS1 gene change. You would take either taletrectinib or a placebo (inactive pill) for about a year after surgery.
Orange, CaliforniaAges 18 years+ - NCT03191149RecruitingPhase 2
Osimertinib for lung cancer with an EGFR exon 20 change
This Phase 2 study tests osimertinib (a targeted lung cancer pill) in people with advanced non-small cell lung cancer (NSCLC) whose tumors have an EGFR exon 20 insertion. It aims to see how well osimertinib works for this specific EGFR mutation and how safe it is.
Burbank, CaliforniaAges 18 years+ - NCT06014827RecruitingPhase 2
Targeted radiation and osimertinib for lung cancer with EGFR mutation
This trial tests a new approach for patients with advanced non-small cell lung cancer that has a specific EGFR mutation (Ex19del or L858R) and has started to grow again after at least six months on osimertinib. It combines two types of focused radiation with continued osimertinib to treat only the progressing spots while keeping the rest of the disease under control.
Duarte, CaliforniaAges 18 years+ - NCT05642572RecruitingPhase 2
Test drug combinations for EGFR- and MET-changed lung cancer

What taking part in a nsclc stage iv 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.
