IN10018 Monotherapy or in Combination With Docetaxel in Gastric or GEJ Adenocarcinoma

A Phase I, Open-label Clinical Trial to Evaluate Safety, Tolerability, Antitumor Activities and Pharmacokinetics of IN10018 as Mono or Combination Therapy in Locally Advanced or Metastatic Gastric or Gastroesophageal Junction Adenocarcinoma

This is a phase I, multi-center clinical trial to evaluate the safety, tolerability, antitumor activities and pharmacokinetics of IN10018 as monotherapy or in combination with docetaxel in previously-treated locally advanced or metastatic gastric or gastroesophageal junction (GEJ) adenocarcinoma.

Study Overview

• Status: Completed
• Conditions: Gastric Cancer
• Intervention / Treatment: Drug: IN10018; Drug: Docetaxel

Detailed Description

Eligibility patients will be enrolled into the study and assigned to treatment groups: 1) IN10018 monotherapy group, and 2) IN10018+Docetaxel combination group. This study contains 2 parts of dose escalation and dose expansion for each treatment group. The monotherapy group will enroll patients failed to respond to standard therapy or standard or curative therapy does not exist or is not tolerable, and explore IN10018 monotherapy RP2D with the starting dose of IN10018 100mg QD per 3+3 design. The combination group will enroll patients who have disease progression within 3 months after at least first-line therapy, and explore IN10018+docetaxel RP2D with the starting dose of IN10018 100mg QD + docetaxel 75mg/m2 per 3+3 design. The dose expansion part will start after attaining the RP2D of IN10018 monotherapy and IN10018+docetaxel combination therapy.

• Accepts Healthy Volunteers: No
• Genders Eligible for Study: All

Description

Inclusion Criteria:

• 1.Has histologically or cytologically confirmed diagnosis of locally advanced and/or metastatic gastric or GEJ adenocarcinoma.

  • For monotherapy, participants need to be failed to respond to standard therapy or standard or curative therapy does not exist or is not tolerable.
  • For combination therapy, participants need to have disease progression within 3 months after at least first-line therapy.
• 2.Has at least one measurable tumor lesion per RECIST 1.1.
• 3.Has an ECOG performance status of 0 or 1.
• 4.Estimated life expectancy is more than 3 months.
• 5.Adequate organ and bone marrow functions.
• 6.Has been fully informed and provided written informed consent for the study

Exclusion Criteria:

• 1.Has other histological types other than adenocarcinoma.

• 2.For participants with HER2/neu positive tumors or have an unknown tumor status, need to match the following:

  • If HER2/neu positive, participant must have documentation of disease progression on trastuzumab or other anti-HER2/neu therapy.
  • Participants with unknown status must have their HER2/neu status determined locally. If HER2/neu-negative, the participant will be eligible. If HER2/neu-positive, the participant must have documentation of disease progression on trastuzumab or other anti-HER2/neu therapy.
