Recruiting studies
- NCT05894239RecruitingPhase 3
Tested targeted drug for HER2-positive breast cancer with PIK3CA changes
This Phase 3 study tests inavolisib plus Phesgo versus placebo plus Phesgo in people whose breast cancer has both HER2-positive and PIK3CA-mutated tumor markers. The goal is to see if adding inavolisib improves how well the treatment controls the cancer and how safe it is.
Gilbert, ArizonaAges 18 years+ - NCT06123338RecruitingPhase 2
Pembrolizumab plus chemo and trastuzumab for HER2+ stomach cancer
This trial tests adding pembrolizumab to standard trastuzumab and chemotherapy for people with HER2-positive stomach or esophageal cancer that can be fully removed with surgery. The goal is to see if this combination improves outcomes before and after surgery.
Boston, MassachusettsAges 18 years+ - NCT07195695RecruitingPhase 3
Zongertinib after surgery for HER2-mutated lung cancer
This trial tests a new pill, zongertinib, against standard of care for people with early-stage (II–IIIB) non-small cell lung cancer that has a specific HER2 mutation in the tyrosine kinase domain. The goal is to see if zongertinib can prevent the cancer from coming back after complete surgical removal.
Fresno, CaliforniaAges 18 years+ - NCT07563595Recruiting
Elacestrant for advanced ER+ HER2- breast cancer with ESR1 mutation
This trial tests elacestrant, a new hormone therapy drug, in women whose advanced or spread breast cancer has stopped responding to first-line hormone treatment. The drug is designed to work against a specific genetic change (ESR1 mutation) that can develop in these cancers.
Freiburg im BreisgauAges 18 years+ - NCT06805812Recruiting
Predicting outcomes of CDK4/6 inhibitors plus hormone therapy for advanced breast cancer
This study looks at how well a type of targeted therapy (called CDK4/6 inhibitors) combined with hormone therapy works as the first treatment for advanced breast cancer that is hormone receptor-positive and HER2-negative. Researchers want to find patterns that could help predict which patients benefit most.
AvianoAges 18 years+ - NCT06043817RecruitingPhase 1/Phase 2
Study of STX-721 for advanced lung cancer with EGFR or HER2 changes
This trial tests a new drug, STX-721, for people with advanced non-small cell lung cancer that has a specific genetic change (EGFR or HER2 exon 20 insertion). The study aims to see if the drug is safe and effective.
Duarte, CaliforniaAges 18 years+ - NCT05786716RecruitingPhase 2/Phase 3
Trastuzumab plus pertuzumab for HER2-mutated cancers
This trial tests whether combining trastuzumab and pertuzumab can treat cancers that have HER2 amplification or an activating HER2 mutation. It looks at people ages 12 and older, and may include both children/teens and adults, using the study drug based on their HER2 test results.
BelfastAges 12 years+ - NCT05216432RecruitingPhase 1
RLY-2608 for PIK3CA-mutant advanced solid tumors and breast cancer
This early study (Phase 1) tests RLY-2608, a targeted cancer drug for tumors with a PIK3CA mutation. It studies the drug alone and combined with hormone therapy (and sometimes CDK4/6 or CDK4 medicines) to see safety, dose, and whether it can shrink tumors.
Tucson, ArizonaAges 18 years+ - NCT07207070RecruitingPhase 3
New drug combination for PIK3CA-mutated breast cancer
This trial tests a new combination of two drugs (JS105 plus dalpiciclib and fulvestrant) against a standard combination (dalpiciclib plus fulvestrant) for people whose breast cancer has a PIK3CA mutation. The goal is to see if adding JS105 helps control the cancer longer.
Beijing, Beijing MunicipalityAges 18–75 - NCT07222215RecruitingPhase 2
Capacitabine with or without elacestrant for ER+ breast cancer
This trial tests if adding a new oral targeted therapy (elacestrant) to standard chemotherapy (capecitabine) works better than chemotherapy alone for people with a specific type of advanced breast cancer that is hormone-sensitive (ER-positive) and has stopped responding to hormone therapy.
Boston, MassachusettsAges 18 years+ - NCT07347600Recruiting
Studying inavolisib for a type of advanced breast cancer
This study tests a targeted therapy called inavolisib for people whose breast cancer has spread (advanced or metastatic), is hormone receptor-positive and HER2-negative, has a PIK3CA mutation, and has stopped responding to hormone therapy. It aims to see if inavolisib is safe and works well for them.
Xiamen, FujianAges 18 years+ - NCT06791161Enrolling by invitation
Adjuvant therapy study for BRCA1/2 positive breast cancer
This study tests if additional treatment after surgery helps prevent breast cancer from returning. It is for people with hormone receptor-positive, HER2-negative breast cancer who have a BRCA1 or BRCA2 gene mutation and a high risk of recurrence.
Beijing, Beijing MunicipalityAges 18–75 - NCT06382948RecruitingPhase 3
Elacestrant and everolimus for ESR1-mutant advanced breast cancer
This trial tests a new combination of two oral targeted therapy pills (elacestrant and everolimus) for people with a specific type of advanced breast cancer. It is for those whose cancer has an ESR1 mutation and has stopped responding to CDK4/6 inhibitors and hormone therapy.
InnsbruckAges 18 years+ - NCT06790693RecruitingPhase 3
Inavolisib plus hormone therapy for advanced breast cancer
This trial tests a new targeted therapy, inavolisib, combined with standard hormone therapy and a CDK4/6 inhibitor for people with a specific genetic mutation (PIK3CA) in their hormone receptor-positive, HER2-negative advanced breast cancer that has not been treated before. It compares this combination to a placebo plus the same standard treatments.
Goodyear, ArizonaAges 18 years+ - NCT05378204Recruiting
Testing DNA repair marker for PARP inhibitor resistance
This study looks at specific DNA “damage repair” proteins as a marker to understand why some BRCA-mutated breast cancers may resist PARP inhibitor treatment. Your biopsy (or existing biopsy) helps researchers study whether these lab markers relate to how well PARP inhibitors work.
BordeauxAges 18 years+ - NCT04150042RecruitingPhase 1
Test of chemotherapy plus your own stem cells for metastatic cancer
This Phase 1 trial tests a treatment approach using standard chemotherapy along with stem cells taken from you to treat metastatic pancreatic or breast cancer. It is mainly designed to check safety and find the best way to give the treatment, and it may offer an option for people whose cancer has spread.
Boston, MassachusettsAges 18 years+ - NCT07383506RecruitingPhase 1
Study of a targeted pill for PIK3CA-mutated advanced cancers
This trial tests a new pill (CGT6297) that targets cancer cells with a specific PIK3CA gene change. It may be an option for people with certain advanced solid tumors, including endometrial or breast cancer, after standard treatments have stopped working.
Scottsdale, ArizonaAges 18 years+ - NCT05564377RecruitingPhase 2
Find targeted cancer treatments using genetic testing
This study matches people with advanced solid tumors to targeted treatment plans based on genetic testing. It also requires tumor sample testing to help doctors choose the most promising therapy for your specific tumor changes.
Birmingham, AlabamaAges Any age - NCT04585750RecruitingPhase 1/Phase 2
Study drug for TP53 Y220C-mutated advanced cancers
This early-phase study tests PC14586 (rezatapopt) in people with advanced or metastatic solid cancers that carry a specific TP53 mutation called Y220C. It mainly looks at safety and how well the treatment may work, sometimes combined with pembrolizumab.

Common questions
- Are there clinical trials for her2 mutation?
- Yes. Clin2 currently lists 43 recruiting her2 mutation studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a her2 mutation trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a her2 mutation trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
