Phase I/IIa Clinical Trial of IMC001 in Patients With Advanced Epithelial Solid Tumors.

Enrolling by invitation · Phase 1/Phase 2

Conditions studied: Epithelial Cancer Patients

In brief

This is an open -label phase I /IIa study designed to evaluate the safety and efficacy of IMC001 in patients with advanced epithelial solid tumors. The study comprises two parts: a phase I dose-escalation phase and a phase IIa phase to further explore and validate efficacy .In the Phase I dose-escalation phase of this study, approximately 7-15 subjects with advanced epithelial solid tumors will be recruited to evaluate the safety and tolerability of autologous IMC001 treatment . In the expansion phase, at least two dose groups will be selected , each recruiting 5-10 subjects. Combined with the subjects from the escalation phase, each dose group will be expanded to approximately 10 subjects to determine the recommended RP2D dose for progression to Phase IIa . DLT ( digestive tract aging) assessment will be performed on subjects in each cohort within 28 days of IMC001 infusion . the RP2D is determined , approximately 6-20 subjects will be initially enrolled at this dose for each selected tumor type to further explore the efficacy and safety of autologous IMC001 for this indication. Subsequently, the protocol may be revised based on statistical hypotheses and regulatory requirements to continue enrolling subjects in the selected tumor types to further validate the efficacy and safety in specific tumor types.the date on which the last participant completes a two-year follow-up visit, is lost to follow up, withdraws informed consent, or dies (whichever occurs first) . It is important to note that for long-term follow-up programs such as ADA, RCL, and VIS (up to 15 years), which require protocol-based follow-up, these follow-ups will be conducted continuously according to protocol and regulatory requirements. However, the actual study participation time for each participant will vary depending on screening requirements, response to treatment, long-term follow-up arrangements, and survival status .

Who can join

Age: 18 and older, up to 75. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• to provide a signed and dated informed consent form before conducting any research-related procedures , and willing and able to comply with all research procedures.
• Applicants must be 18 years of age or older and 75 years of age or younger; both male and female applicants are welcome .
• Subjects with histologically or cytologically confirmed locally advanced/metastatic epithelial solid tumors , including but not limited to subjects with advanced gastric cancer/gastroesophageal junction adenocarcinoma, triple-negative breast cancer, biliary tract tumors, ovarian cancer, colorectal cancer, pancreatic cancer, gastrointestinal and pancreatic neuroendocrine tumors, etc.
• Disease progression or intolerance to standard systemic therapy , including:
• Gastric cancer and gastroesophageal junction adenocarcinoma that have failed or are intolerant of at least two lines of standard systemic therapy. If first-line three-drug combination therapy has failed or is intolerant, enrollment may be made after thorough investigator evaluation.
• Triple-negative breast cancer: Subjects with unresectable locally advanced or metastatic triple-negative breast cancer who have failed at least two lines of standard systemic therapy. All subjects must have previously received taxane therapy, regardless of the stage of disease at the time of treatment.
• Other subjects with epithelial solid tumors who have failed or are intolerant of standard treatment.
• Tumor tissue samples (primary or metastatic, archived or newly collected) from the expected subjects, tested by the central laboratory, are EpCAM histologically positive (defined as tumor cell positivity ≥10% and staining intensity ≥1+).
• The expected survival period of the subjects is ≥12 weeks .
• According to RECIST 1.1 criteria, there should be at least one stably measurable target lesion (where the largest lesion should be ≤4). In the 3×10⁵ CAR -T cells/kg dose group, subjects with evaluable lesions (unmeasurable lesions) can be admitted.
• ECOG performance status score 0-1 .
• The subject has adequate organ and bone marrow function. Laboratory screening must meet the following criteria: all laboratory test results should be within the stable ranges outlined below, and there should be no ongoing supportive treatment. If any laboratory test result is abnormal according to the following criteria, a repeat test may be performed within one week. If the test results still do not meet the following criteria, the subject's screening has failed.
• Blood tests [No intensive blood transfusions (≥2 times within 1 week), platelet transfusions, or cell growth factor injections (excluding recombinant erythropoietin)) within 7 days prior to the test]: Neutrophil count (ANC) ≥1.5×10⁹ / L; Platelet count (PLT) ≥100 × 10⁹ / L; Hemoglobin content (Hb) ≥9.0g / dL; Lymphocyte count ( ALC ) ≥0.5× 10⁹ /L ;
• Liver function: alanine aminotransferase (ALT) ≤ 2.5 × ULN, aspartate aminotransferase (AST) ≤ 2.5 × ULN, serum total bilirubin (TB) ≤ 2 × ULN; for subjects with liver metastases, AST and ALT < 5 × ULN ;
• Kidney function: Serum creatinine ≤1.5×ULN; if serum creatinine >1.5×ULN, creatinine clearance rate >50mL/min is required (according to the Cockcroft-Gault formula); qualitative urine protein ≤1+; if qualitative urine protein ≥2+, a 24-hour urine protein quantification test is required (if the 24-hour urine protein quantification test is <1g, it is acceptable).
• Amylase and lipase ≤1.5×ULN; alkaline phosphatase (ALP) ≤2.5×ULN, and for subjects with bone metastases, ALP <5×ULN ;
• Coagulation function: Activated partial thromboplastin time ≤ 1.5 ULN, prothrombin time ≤ 1.5 × ULN ;
• All toxicities resulting from prior antitumor therapy were reduced to grade 0-1 (according to NCI CTCAE version 5.0) or to a level acceptable to the inclusion criteria.
