A Phase I Study of CG-7321 Monotherapy or Combination Therapy in Advanced Solid Tumors
A Phase I, Open-Label, Multi-Center Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Efficacy of CG-7321 as Monotherapy or in Combination Therapy in Subjects With Advanced Solid Tumors
This is a Phase I, open-label, multi-center study to evaluate the safety, tolerability, pharmacokinetics (PK), and preliminary efficacy of CG-7321 capsules as monotherapy or in combination with fulvestrant in subjects with advanced solid tumors.
The study consists of:
- Part Ia (Monotherapy): Dose escalation (accelerated titration followed by 3+3 design) from 2mg to 50mg twice daily (BID), plus dose expansion cohorts in advanced solid tumors including HR+/HER2- breast cancer, ovarian cancer, gastric cancer, and other tumor types.
- Part Ib (Combination Therapy): Dose escalation of CG-7321 combined with fulvestrant in HR+/HER2- advanced breast cancer.

Detailní popis
CG-7321 is a novel oral small molecule inhibitor of cyclin-dependent kinases (CDKs), being developed for the treatment of advanced solid tumors. Preclinical studies have demonstrated potent anti-tumor activity in breast cancer, ovarian cancer, and gastric cancer models.
This Phase I study employs a dose escalation design to determine the maximum tolerated dose (MTD) and recommended Phase II dose (RP2D) of CG-7321.
Part Ia evaluates CG-7321 monotherapy with dose levels of 2mg, 6mg, 12mg, 20mg, 30mg, 40mg, and 50mg BID in a 28-day cycle. Single dosing (Cycle 0) followed by multiple dosing (Cycle 1 onwards) will be evaluated.
Part Ib evaluates CG-7321 in combination with fulvestrant in HR+/HER2- advanced breast cancer patients.
Dose expansion cohorts will further evaluate safety, PK, and preliminary efficacy at or near the RP2D in specific tumor types.
Eligible subjects include patients with histologically/cytologically confirmed advanced or metastatic solid tumors who have failed, are intolerant to, or have no effective standard therapy available, or who refuse standard treatment.
The Part Ia (monotherapy dose escalation) will be conducted first.
