Onconic Therapeutics Files Phase 3 IND for H. pylori Eradication Indication of Jakubozin (JP-1366) – Expansion of Approved Drug's Label, Limited Short-Term Impact but Positive Long-Term Value


  • Onconic Therapeutics has submitted a Phase 3 clinical trial plan amendment (IND) to the Ministry of Food and Drug Safety (MFDS) to add an H. pylori eradication indication for its Jakubozin (JP-1366, zastaflazancitrate)-based triple therapy.
  • This trial aims to expand the label of the already approved domestic new drug No. 37 Jakubozin (20mg), evaluating non-inferiority versus lansoprazole in 414 patients across 22 institutions, including Catholic University of Korea Incheon St. Mary's Hospital, in a multicenter, randomized, double-blind, active-controlled, non-inferiority design.
  • The study involves 2 weeks of treatment followed by a 13C-UBT test at least 4 weeks post-treatment to confirm eradication. If approved, the trial duration is approximately 24 months.
  • While the IND application marks entry into Phase 3, the statistical probability of final drug approval is around 10%, so investors should consider clinical failure risk. However, Jakubozin is already approved; gaining this additional indication could extend product life cycle and boost revenue.
  • [AI Summary]This disclosure is a Phase 3 IND application for label expansion of an already approved drug. Short-term stock price impact is limited, but successful addition of the H. pylori indication would open a new market, enhancing long-term enterprise value. However, investors must account for the ~10% likelihood of final approval.
