Autologous B7-H3 Chimeric Antigen Receptor T Cells in Previously Treated Extensive-Stage Small Cell Lung Cancer With Recurrent or Refractory Disease
A Phase I Study to Assess the Safety and Antitumor Activity of Autologous B7-H3 Chimeric Antigen Receptor T Cells in Previously Treated Extensive-Stage Small Cell Lung Cancer With Recurrent or Refractory Disease
Forrás: ClinicalTrials.gov · Utoljára frissítve: 2026. okt. 29.
Rövid összefoglaló (regiszter, angolul)
Background: Small cell lung cancer (SCLC) is the deadliest form of lung cancer. Extrapulmonary neuroendocrine cancer (EPNEC) is a similar type of cancer that develops anywhere other than the lungs. EPNEC is also deadly. B7-H3 is a protein often found in SCLC and EPNEC tumor cells. Researchers can modify a person s own T cells, or immune cells, to target B7-H3. When these modified T cells are returned to the body-a treatment called B7-H3 chimeric antigen receptor (CAR) T cell therapy-they may help kill cancer cells. Objective: To test B7-H3 CAR T cell therapy in people with SCLC or EPNEC. Eligibility: People aged 18 years and older with SCLC or EPNEC that either did not respond or returned after treatment. Design: Participants will be screened. They will have blood tests and tests of their heart function. They will have imaging scans. Participants will undergo apheresis: Blood will be taken from the body through a needle. The blood will pass through a machine that separates out the T cells. The remaining blood will be returned to the body through a different needle. The collected T cells will be altered to make them attack cells with B7-H3. Participants will be in the hospital for at least 15 days. They will receive chemotherapy drugs to prepare their body for the treatment. These drugs will be given through a tube attached to a needle inserted into a vein. The modified T cells will be infused through a vein. Participants will remain in the hospital until they are well enough to go home. Follow-up visits will continue for 15 years....

Ki nem vehet részt
Szó szerint a(z) ClinicalTrials.gov forrásból, témák szerint csoportosítva. Hogy ki vehet részt, azt csak a vizsgálat csapata dönti el.
Korábbi kezelés
- Prior gene therapy using an integrating vector (except for autologous B7-H3 CAR T cells retreatment).
- History of any previous allogeneic hematopoietic stem cell transplant.
Más betegség
- History of anaphylactic reactions attributed to anti-B7-H3 antibodies or compounds of similar chemical or biologic composition to autologous B7-H3 CAR T cells, cyclophosphamide, fludarabine, or other agents used in this study.
- Infection exposure with the human immunodeficiency virus (HIV), hepatitis B virus (HBV), or hepatitis C virus (HCV) as defined below:
- Positive serology for HIV.
- Active HBV infection as demonstrated by test for hepatitis B surface antigen (HBsAg).
- Positive serology for HCV.
- Presence of fungal, bacterial, viral, or other infection is permitted if responding to active treatment.
- Central Nervous System (CNS) disorder such as cerebrovascular ischemia/hemorrhage, dementia, cerebellar disease, or autoimmune disease with CNS involvement that may impair the ability to evaluate neurotoxicity.
- Uncontrolled intercurrent illness or medical condition(s) evaluated by medical history, physical exam, electrocardiogram (ECG) or situations that would unacceptably increase risk for the participant or impair the ability to evaluate the endpoints of the study.
Laborértékek
- Pregnancy confirmed with beta-human chorionic gonadotropin (beta-HCG) serum or urine pregnancy test in IOCBP at screening.

- INCLUSION CRITERIA:
- Age >=18 years old.
- Histologically confirmed small cell lung cancer (SCLC) or extrapulmonary neuroendocrine cancers (EP-NEC) that has recurred following or is refractory to first-line therapy. Note: small cell cancers of non-lung primary sites are also eligible.

- Total bilirubin <=2 X institutional ULN.
- Creatinine <=1.5 X institutional ULN OR creatinine clearance (CrCl) >= 50 mL/min/1.73m\^2 (calculated by the Chronic Kidney Disease Epidemiology Collaboration [CKD-EPI] formula or calculated eGFR provided by a laboratory).
- Absolute Neutrophil Count (ANC) >= 750/mcL.
- Platelet count >= 75,000/mcL.
- An absolute lymphocyte count (ALC) >=300/mcL and CD3+ cell count >=150/mcL.
- Normal cardiac ejection fraction as defined by >= 45% by echocardiogram (ECHO) at screening.
