ClinConnect Summary

This clinical trial is studying a new treatment called STR-P004 for patients with a type of cancer known as non-Hodgkin lymphoma, specifically those whose cancer has come back or hasn’t responded to previous treatments. The goal of the study is to find out how safe STR-P004 is, how well it works, and how it behaves in the body over time. Participants will receive multiple doses of this treatment, and the researchers will closely monitor their response and any side effects they experience.

To join the trial, participants must be at least 18 years old and have a confirmed diagnosis of certain types of B-cell non-Hodgkin lymphoma. They should have already undergone at least two prior treatments without successful results. Participants will have regular check-ins with the study team, and they will need to meet specific health criteria to ensure their safety during the trial. It’s important to note that this trial is not yet recruiting participants, so those interested will need to wait until it officially starts.

Eligibility criteria

• Inclusion Criteria:
• * Subjects with relapsed/refractory CD19-positive B-cell non-Hodgkin's lymphoma:
• • 1. Age ≥18 years, regardless of gender;
• • 2. Life expectancy \>12 weeks;
• • 3. ECOG score of 0-2;
• • 4. Diagnosis of B-cell non-Hodgkin's lymphoma confirmed by cytology or histopathology according to WHO 2016 criteria, including: diffuse large B-cell lymphoma (DLBCL), primary mediastinal large B-cell lymphoma (PMBCL), transformed follicular lymphoma (TFL), and high-grade B-cell lymphoma (HGBCL);
• 5. Pathologically confirmed B-cell non-Hodgkin's lymphoma meeting one of the following conditions:
• • 1. Relapsed/refractory B-cell non-Hodgkin's lymphoma with the best response of SD or PD after receiving at least two lines of adequate therapy, the best response of PD during or after the last line of treatment, or the best response of SD after receiving at least two cycles of the last line of treatment;
• • 2. For relapse or PD within 12 months after autologous stem cell transplantation (ASCT) for B-cell non-Hodgkin's lymphoma, if salvage therapy is administered, no response (SD/PD) to the last treatment is required; for relapse or PD more than 12 months after ASCT, salvage therapy is needed, and no response (SD/PD) to the last treatment is required;
• • 6. Hemoglobin ≥80 g/L, neutrophils ≥1.0 × 109/L, platelets ≥75 × 109/L;
• • 7. At least one measurable tumor lesion according to the 2014 Lugano response criteria;
• 8. Hepatic and renal function, as well as cardiopulmonary function, meet the following requirements:
• • 1. Serum creatinine ≤1.5 × ULN or creatinine clearance ≥50 mL/min (calculated by the Cockcroft-Gault formula);
• • 2. Ejection fraction \>50%, with no clinically significant pericardial effusion or pleural effusion detected;
• • 3. Baseline oxygen saturation \>92%;
• • 4. Total bilirubin ≤1.5 × ULN (≤5 × ULN for Gilbert syndrome);
• • 5. ALT and AST ≤3 × ULN (≤5 × ULN for patients with liver metastases).
• • 9. Capable of understanding the study and having signed the informed consent form.
• Exclusion Criteria:
• * Subjects meeting any of the following conditions will not be eligible for participation:
• • 1. History of malignancies other than diffuse large B-cell lymphoma (DLBCL), primary mediastinal large B-cell lymphoma (PMBCL), transformed follicular lymphoma (TFL), or high-grade B-cell lymphoma (HGBCL) within 5 years prior to screening, except for adequately treated cervix carcinoma in situ, basal cell or squamous cell skin cancer, localized prostate cancer after radical surgery, ductal carcinoma in situ after radical surgery, or thyroid cancer after radical surgery;
• • 2. Presence of any of the following high-risk factors: sum of product of diameters (SPD) of lesions (all measurable lesions ≥1.5 cm in the longest diameter) ≥100 cm; bulky disease (single lesion ≥10 cm); lesions located in the pharynx or trachea with pressure symptom; lesions adjacent to critical hollow organs such as the gastrointestinal tract or bile ducts, where enlargement may press or invade surrounding organs and impair their functions;
• • 3. Subjects who have not completed a washout period of at least 5 half-lives since their last anticancer therapy (including I/O therapy) prior to the first dose of study treatment; for anticancer therapies with a half-life \>5 days, a washout period \>14 days is acceptable; or participation in any other clinical study within 4 weeks prior to the first treatment;
• • 4. Any of the following conditions: positive for hepatitis B surface antigen (HBsAg) and/or hepatitis B e antigen (HBeAg); positive for hepatitis B e antibody (HBe-Ab) with HBV-DNA copy number above the lower limit of detection; positive for hepatitis C antibody (HCV-Ab); positive for anti-Treponema pallidum antibody (TP-Ab); positive for human immunodeficiency virus (HIV) antibody; EBV-DNA or CMV-DNA copy number above the lower limit of detection;
• • 5. Any unstable systemic disease, including but not limited to active infection (except for local infections), unstable angina, cerebrovascular accident or transient ischemic attack (within 6 months prior to screening), myocardial infarction (within 6 months prior to screening), congestive heart failure (New York Heart Association \[NYHA\] class ≥III), severe arrhythmia requiring medication, or hepatic, renal, or metabolic disorders;
• • 6. Any uncontrolled active condition that may interfere with study participation;
• • 7. Any condition deemed by the investigator to compromise subject safety or interfere with the study objective;
• • 8. Pregnant or breastfeeding women, or subjects who plan to become pregnant during the treatment period or within 1 year after treatment completion, or male subjects whose partners plan to become pregnant within 1 year after cell infusion;
• • 9. Subjects receiving systemic corticosteroid therapy within 14 days prior to enrollment and judged by the investigator to require long-term use of systemic corticosteroid during treatment (excluding inhaled or topical use);
• • 10. Presence of central nervous system or brain metastasis symptoms or receiving treatment for central nervous system or brain metastasis (radiotherapy, surgery, or other therapy) within 3 months prior to enrollment;
• • 11. Subjects with conditions that impair their ability to provide written informed consent or comply with study procedures, or those unwilling or unable to adhere to study requirements.
• • 12. Subjects deemed unsuitable for participation in this study by the investigator.
