Insights
The completion of enrollment for a Phase 2 clinical trial is a critical step in the development of new cancer treatments. The focus on advanced gastroesophageal junction and gastric cancer, which are typically aggressive and have poor prognosis, highlights the unmet medical need in this area. The combination of Leap's DKN-01 with tislelizumab could represent a significant advancement in treatment options if the study results demonstrate improved progression-free survival (PFS) and overall survival compared to the current standard of care. The use of RECIST v1.1 as a measurement for objective response rate ensures that the study outcomes will be comparable to other clinical trials in oncology, facilitating a clear interpretation of efficacy.
From a research perspective, the investigation into the efficacy of DKN-01, an anti-Dickkopf-1 (DKK1) antibody, is of particular interest. DKK1 is involved in tumor-induced immunosuppression and bone loss associated with cancer metastasis. The therapeutic hypothesis suggests that inhibiting DKK1 could enhance the immune response against cancer cells and potentially reduce metastatic progression. The study's design, which includes a randomized controlled trial with a primary objective focused on progression-free survival (PFS), provides a robust framework for evaluating the true clinical benefit of the therapy. The secondary objectives, including overall survival and objective response rate, will further elucidate the impact of the treatment on disease trajectory.
For investors, the completion of enrollment in the Phase 2 trial is a pivotal event that could influence Leap Therapeutics' stock valuation. The potential success of DKN-01 in combination with tislelizumab may open up a significant market opportunity within oncology, particularly for HER2-negative gastroesophageal cancers. The data expected over the course of the year will be a key driver for the company's share performance. Investors will be monitoring not only the primary and secondary endpoints but also the safety profile, as this can affect the drug's commercial viability and competitive positioning. It is also important to consider the partnership with BeiGene, as successful trial results could lead to further collaboration opportunities and revenue-sharing agreements.
CAMBRIDGE, Mass. , Jan. 2, 2024 /PRNewswire/ -- Leap Therapeutics, Inc. (Nasdaq:LPTX), a biotechnology company focused on developing targeted and immuno-oncology therapeutics, today announced that enrollment has been completed in the randomized controlled Part C of the DisTinGuish study evaluating DKN-01, Leap's anti-Dickkopf-1 (
"The completion of enrollment in Part C of the DisTinGuish study is an important milestone and continues to underscore the high level of interest from both patients and investigators in DKN-01," said Cynthia Sirard, M.D., Chief Medical Officer of Leap. "Long-term follow-up data from Part A of the study clearly demonstrated the potential to induce durable responses and clinically meaningful survival outcomes in first-line advanced gastroesophageal junction and gastric cancer patients. We expect Part C to further validate the potential of DKN-01 and tislelizumab combination therapy and look forward to having initial data from Part C over the course of this year."
Part C of the DisTinGuish study (NCT0436380) is a Phase 2, randomized, open-label, multicenter study of DKN-01 in combination with tislelizumab and chemotherapy in first-line patients with advanced gastroesophageal adenocarcinoma. Part C enrolled 170 first-line, HER2-negative patients. Patients were randomized 1:1 to evaluate DKN-01 in combination with tislelizumab and standard of care (SOC) chemotherapy, compared to tislelizumab and SOC chemotherapy alone. The primary objective is progression-free survival (PFS) in
