Elios Therapeutics Announces Interim Phase IIb Results of TLPLDC, a Personalized Therapeutic Cancer Vaccine for the Treatment of Melanoma, at the 2018 American Society of Clinical Oncology (ASCO) Annual Meeting
Interim Phase IIb Data Show Promising Reduction In Risk of Recurrence and a Well-Tolerated Safety Profile in Patients with Resected, High-Risk Melanoma
AUSTIN, Texas, June 1, 2018 /PRNewswire/ -- Elios Therapeutics, a biopharmaceutical company developing innovative autologous, particle-delivered, dendritic cell cancer vaccines, today announced interim data from the ongoing prospective, randomized, double-blind, placebo-controlled Phase IIb clinical trial of the TLPLDC (tumor lysate, particle-loaded, dendritic cell) vaccine in patients with Stage III and IV, resected melanoma will be presented at the American Society of Clinical Oncology (ASCO) Annual Meeting on June 4, 2018 in Chicago, Illinois (Abstract # 9525).
The planned interim analysis was conducted after the first 120 patients enrolled in the trial had been randomized and treated for at least 6 months. In the per treatment population, TLPLDC showed a meaningful 32 percent reduction in the relative risk of recurrence (TLPLDC 29.4 percent vs. placebo 43.3 percent, p = 0.07) with a median follow-up of 12.6 months. There was no difference in recurrence in the intent-to-treat population (TLPLDC 56.6 percent, placebo 54.1 percent, p=0.65) with 11.9 months median follow-up. Overall, TLPLDC was safe and well-tolerated. In the study, only 33 percent of participants experienced any adverse event, and 98.6 percent of those were grade 1 and 2 events that included injection site reactions and flu-like symptoms. No serious adverse events were reported.
"The interim data evaluating the TLPLDC vaccine as an adjuvant treatment to prevent melanoma recurrences are very encouraging, suggesting clinical activity and demonstrating an attractive safety profile," said George E. Peoples, M.D., chief medical officer at Elios Therapeutics. "These data, combined with the recently reported results of our open label Phase II study demonstrating the synergistic effects of the TLPLDC vaccine in combination with checkpoint inhibitors, suggest a strong rationale for further clinical development in a Phase III program."
Detailed results from the ongoing Phase IIb study evaluating TLPLDC will be presented on Monday, June 4, 2018:
• Abstract 9525 (Poster #352): Interim analysis of a prospective,
randomized, double-blind, placebo-controlled, Phase IIb trial of the TLPLDC vaccine to prevent recurrence in resected Stage III or IV melanoma patients
• Presenter: John W. Myers, M.D., San Antonio Military Medical Center,
• Data/Time: Monday, June 4, 2018 from 1:15 PM - 4:45 PM CDT
• Session: Melanoma/Skin Cancers Poster Session – Hall A
About the Study Design
Elios Therapeutics is conducting a prospective, randomized, double-blind, placebo-controlled Phase IIb trial to evaluate the safety and efficacy of TLPLDC in patients with resected Stage III and IV melanoma. The primary endpoint is 2 year disease-free survival (DFS).
In the study, 120 participants were randomized (2:1) to receive either TLPLDC vaccine or placebo to prevent recurrence. TLPLDC or placebo vaccines were initiated within 3 months of completion of standard of care (SoC) therapies and were given at 0, 1, 2, 6, 12, and 18 months. Study participants were followed for recurrence per SoC. The interim analysis was pre-specified at 6 months from randomization of the 120th study participant. Survival analysis was performed on the intent-to-treat and per treatment populations. The latter excludes early recurrences during the primary vaccine series (up to 6 months).
The TLPLDC (tumor lysate, particle-loaded, dendritic cell) vaccine is an autologous, personalized, therapeutic cancer vaccine designed to stimulate the immune system to recognize tumor cells and fight a patient's specific cancer. TLPLDC is made from a patient's own tumor and dendritic cells – the most potent antigen-presenting cells in the body. Once TLPLDC is injected, the tumor lysate-loaded dendritic cells present the tumor antigens to the immune system, stimulating the induction of tumor-specific, activated T cells that are able to find and destroy tumor cells that may remain in the body. TLPLDC is currently being studied as a monotherapy and in combination with SoC checkpoint inhibitor therapy in a Phase IIb clinical trial for the treatment of late-stage melanoma at leading academic cancer centers in the United States.
