Study Endpoints

Primary Endpoints

To evaluate the safety and tolerability of single and multiple ascending oral doses of CG001419 in healthy subjects
Up to 7 days of dosing

Safety and tolerability based on adverse events (AEs)

Phase 1: Maximum Tolerated Dose (MTD)
After the first treatment cycle(each cycle is 28 days), DLT assessment

Defined as the highest dose level at which no more than 1/6 of the subjects experience dose-limiting toxicity(DLT) during the DLT assessment period.

Phase 1: Recommended Phase 2 Dose (RP2D)
Approximately 3 years

Defined as the optimal Phase II dosing regimen explored and selected based on the comprehensive evaluation of the drug's safety, tolerability, pharmacokinetic profile, and efficacy.

Phase1: Incidence of Adverse Events [Safety and Tolerability]
Approximately 3 years

According to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v5.0, evaluate the safety and tolerability of CG001419 at different doses in the treatment of advanced solid tumors.

Phase 2: Overall response rate (ORR)
The entire test cycle, approximately 8 years.

The proportion of subjects whose best overall response is Complete Response(CR) or Partial Response(PR) in the study assessed by Independent Central Review(IRC) according to Response Evaluation Criteria in Solid Tumors(RECIST) v1.1.

Secondary Endpoints

To further characterize the PK of CG001419 in healthy subjects
Up to 7 days of dosing
Objective Response Rate (ORR)
The entire test cycle, approximately 8 years.
Disease Control Rate(DCR)
The entire test cycle, approximately 8 years.

Frequently asked questions about CG001419

What is CG001419 used for?

CG001419 is an investigational small molecule being studied for the treatment of solid tumors harboring NTRK gene fusions. It is also being evaluated in a healthy volunteer study for pain management. The drug is administered orally as tablets and is currently in Phase 1 clinical development.

What does CG001419 target?

CG001419 targets TRK, a protein involved in cell growth and survival. By inhibiting TRK, the drug aims to address cancers driven by NTRK gene fusions. This targeted approach is being studied in patients with locally advanced or metastatic solid tumors that harbor NTRK gene abnormalities.

Who makes CG001419?

CG001419 is being developed by Pulmatrix, Inc., a biopharmaceutical company. The company is conducting clinical trials to evaluate the safety and efficacy of this oral small molecule in patients with NTRK fusion-positive solid tumors and in healthy volunteers for pain management.

What phase is CG001419 in?

CG001419 is in Phase 1 clinical development. It is being studied in two trials: a completed Phase 1 study in healthy subjects and a recruiting Phase 1/2 study in adults with solid tumors harboring NTRK gene abnormalities. The drug is investigational and not yet approved.

What clinical trials is CG001419 in?

CG001419 is being evaluated in two clinical trials. NCT06636500 is a completed Phase 1 study in healthy subjects in Australia, enrolling 72 participants. NCT07394374 is a recruiting Phase 1/2 study in China for adults with solid tumors harboring NTRK gene fusions, with a target enrollment of 42 participants.

Is CG001419 the same as CG001419 tablets?

Yes, CG001419 tablets is the oral formulation of CG001419. The drug is administered as tablets and is being studied in clinical trials for the treatment of solid tumors with NTRK gene fusions. The tablet form is the investigational product being evaluated in patients.
