A Study of DCC-2618 (Ripretinib) In Patients With With Advanced Gastrointestinal Stromal Tumors (GIST)

Phase 2
Completed
Conditions
Gastrointestinal Stromal Tumors
Interventions
Registration Number
NCT04282980
Lead Sponsor
Zai Lab (Shanghai) Co., Ltd.
Brief Summary

The primary objective of this trial is to evaluate the progress free survival (PFS) of DCC-2618 in patients with advanced gastrointestinal stromal tumors who have progressed with prior anticancer therapies based on independent radiologic review.

Detailed Description

The primary objective of this trial is to evaluate the progress free survival (PFS) of DCC-2618 in patients with advanced gastrointestinal stromal tumors who have progressed with prior anticancer therapies based on independent radiologic review. This study enrolled 39 subjects of 9 sites in China mainland, and all enrolled subjects received DCC-2618 after enrollment as treatment.

The study used EDC to collect patient data and IRT system for patient randomization, using Imaging Endpoints as the central image to evaluate the PFS.

Inclusion Criteria
  • Male or female patients ≥18 years of age.
  • Patients with advanced gastrointestinal stromal tumors.
  • Subjects who have progressed or documented intolerance after previous treatments.
  • Sign informed consent, understand the Protocol and could follow the Protocol.
  • The subject had at least one measurable lesion.
  • Adequate organ function and bone marrow reserve
Exclusion Criteria
  • Treatment with anticancer therapy, including investigational therapy, or investigational procedures within 14 days or 5 x the half-life (whichever is longer) prior to the first dose of investigational drug.
  • Prior treatment with DCC-2618.
  • Previously or currently has an additional malignancy that is progressing or required active treatment, which may interfere with the safety or efficacy evaluation of DCC-2618.
  • Patient has known active central nervous system metastases.
  • New York Heart Association class II - IV heart disease, active ischemia or any other uncontrolled cardiac condition.
  • Arterial thrombotic or embolic events within 6 months before the first dose of investigational drug.
  • Venous thrombotic events within 3 months before the first dose of investigational drug.
  • 12-lead electrocardiogram (ECG) demonstrating QT interval corrected by Fridericia's formula >450 ms in males or >470 ms in females at screening or history of long QT interval syndrome.
  • Left ventricular ejection fraction (LVEF) <50% at screening.
  • Use of known substrates or inhibitors of breast cancer resistance protein (BCRP) transporters within 14 days or 5 x the half-life (whichever is longer) prior to the first dose of investigational drug.
  • Major surgeries within 4 weeks of the first dose of investigational drug.
  • Any other clinically significant comorbidities, which in the judgment of the investigator, could compromise compliance with the protocol, interfere with interpretation of the study results, or predispose the patient to safety risks.
  • Active viral infections.
  • If female, the patient is pregnant or lactating, or plans to become pregnant during the study treatment period.
  • Known allergy or hypersensitivity to any component of the investigational drug.
  • Gastrointestinal abnormalities.
  • Any active hemorrhages, excluding hemorrhoids or gum bleeding.

Primary Outcome Measures
NameTimeMethod
Progression-Free Survival (PFS)Approximately 10 months since the first subject enrolled.

Progression-Free Survival (PFS) is defined as the time from the first dose of study drug to the first occurrence of disease progression based on independent radiology review or death due to any cause (whichever occurred first).

Secondary Outcome Measures
NameTimeMethod
Objective Response Rate (ORR)Approximately 15 months since the first subject enrolled.

The objective response rate (ORR) is defined as the percentage of participants who achieved confirmed complete response (CR) or partial responses (PR) based on independent radiology review.

Overall Survival (OS)Approximately 28 months since the first subject enrolled.

Overall survival (OS) is defined as the time from the first dose of study drug to all-cause death.

Time to Best Response (TBR)Approximately 15 months since the first subject enrolled.

Time to Best Response(TBR) based on independent radiology review is defined as the duration from the date of the first dose of the investigational drug to the date of confirming the best response.

Disease Control Rate (DCR) (Confirmed CR + Confirmed PR + SD) for 12 WeeksApproximately 15 months since the first subject enrolled.

Disease control rate (DCR) based on independent radiology review (confirmed CR + confirmed PR + SD for 12 weeks)
