Varlitinib in Combination With mFOLFOX6 for Advanced or Metastatic Gastric Cancer (First Line)

Phase 2
Completed
Conditions
Gastric Cancer
Interventions
Drug: Placebo
Drug: mFOLFOX6
Registration Number
NCT03130790
Lead Sponsor
ASLAN Pharmaceuticals
Brief Summary

This protocol for Varlitinib is developed for the treatment of Gastric Cancer. Varlitinib (also known as ASLAN001) is a small-molecule, adenosine triphosphate competitive inhibitor of the tyrosine kinases - epidermal growth factor receptor (EGFR), human epidermal growth factor receptor (HER)2, and HER4. Varlitinib may be beneficial to subjects with cancer by simultaneous inhibition of these receptors. The purpose of this study is to determine the safety and efficacy of Varlitinib in combination with mFOLFOX6 for the treatment of Gastric Cancer. Treatment groups are Varlitinib+mFOLFOX6 and Placebo+mFOLFOX6.

Phase 3 is planned to recruit 350 patients. Anticipated completion date in Dec 2022. Not yet recruiting.

Exclusion Criteria
  1. Subject with HER-2 over expression at level of +++ determined by IHC or subject confirmed HER2 2+ by IHC with HER2 gene amplification confirmed by Fluorescence in situ hybridization (FISH) in the central lab.

Subjects with an uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, New York heart Association class III or IV congestive heart failure, unstable angina pectoris, clinically significant cardiac arrhythmia, diabetes, hypertension, or psychiatric illness/social situations that would limit compliance with study requirements.
  7. Subjects with any history of other malignancy unless in remission for more than 1 year. (Nonmelanoma skin carcinoma and carcinoma-in-site of uterine cervix treated with curative intent is not exclusionary).
  8. Female subjects who are pregnant or breast feeding.

  11. Are currently on or have received anti-cancer therapy, radiation or local treatment within the past 28 days
  12. Subject with unresolved or unstable serious toxicity (≥ CTCAE 4.03 Grade 2) from prior administration of another investigational drug and/or prior cancer treatment(excluding hair loss)
  13. Subjects with a known history of human immunodeficiency virus (HIV), decompensated cirrhosis, hepatitis B infection with hepatitis B virus DNA exceeding 2000 IU/mL or hepatitis C (treatment naïve or after treatment without sustained virologic response).
  14. Known history of drug addiction within the past 1 year.
  15. Subjects who need continuous treatment with proton pump inhibitors during the study period.
  16. Any history or presence of clinically significant cardiovascular, respiratory, hepatic, renal, hematologic, gastrointestinal, endocrine, immunologic, dermatologic, neurologic or psychiatric disease or any other condition which in the opinion of the Investigator could jeopardize the safety of the subject or the validity of the study results.
