Details and patient eligibility

About

This is a phase 1, single-arm, open-label, dose escalation and expansion study of LCAR-G08 in adult subjects with advanced gastrointestinal tumors expressing guanylyl cyclase C (GCC).

Full description

This is a phase 1, single-arm, open-label, dose escalation and expansion study to evaluate the safety, tolerability, pharmacokinetics, and anti-tumor efficacy profiles of the cell-based LCAR- G08 in subjects with guanylyl cyclase C (GCC)-positive advanced gastrointestinal tumors. Subjects who meet the eligibility criteria will receive LCAR-G08 infusion. The study will include the following sequential phases: screening, pre-treatment (cell product preparation; lymphodepleting chemotherapy), treatment and follow up.

  • Aged 18 to 70 years, either sex.
  • GCC immunohistochemistry (IHC) staining is positive.
  • At least one measurable tumor lesion according to RECIST v1.1.

Exclusion criteria

  • Previous CAR-T cell, T cell receptor-engineered (TCR) T cell, or therapeutic tumor vaccination treatment within the past 6 months; and the corresponding CAR-T, TCR-T cells can still be detected.
  • Ever received any treatment targeting GCC.
  • Prior antitumor therapy with insufficient washout period.
  • Brain metastases.
  • Pregnant or lactating women.

  • Severe underlying disease.
  • Presence of other serious pre-existing medical conditions that may limit patient participation in the study.Any condition that, in the investigator's judgment, will make the subject unsuitable for participation in this study.
