SYDNEY, Australia, Aug. 07, 2018 (GLOBE NEWSWIRE) -- Immutep Limited (ASX: IMM; NASDAQ: IMMP) ("Immutep“ or “the Company“), a biotechnology company developing novel immunotherapy treatments for cancer and autoimmune diseases, provides an operational update on the Company’s ongoing clinical development of eftilagimod alpha (“efti” or “IMP321”) as well as the Company’s partnered clinical programs.
TACTI-mel Part B Patient Recruitment Completed
Immutep reports that the final patient in Part B of the ongoing TACTI-mel Phase I clinical trial in Australia has now been recruited and is receiving treatment.
The TACTI-mel (Two ACTive Immunotherapeutics in melanoma) trial is evaluating the combination of efti and KEYTRUDA® (pembrolizumab) in unresectable or metastatic melanoma patients. Following the study’s expansion earlier this year, an additional cohort of six patients was recruited to the study, bringing the total number of patients participating in the trial to 24.
The completion of patient recruitment occurred as the final patient in the new cohort received their first dose of the two drugs. The actual cohort of patients will receive 30 mg of efti in combination with pembrolizumab starting at cycle one day one of pembrolizumab. Patients will be treated for up to 12 months.
Safety assessment is the main objective of this study. Interim data reported to date from the first three cohorts indicates that the combination treatment is delivering long lasting and durable responses in a subset of patients.
TACTI-002 IND Approved by U.S. FDA
Immutep announced the approval of its IND by the U.S. FDA on 31 July 2018. Immutep continues to progress the relevant regulatory and ethics approvals needed to commence its planned TACTI-002 Phase II clinical study, as well as continuing the site selection process. The trial is set to commence in the second half of calendar year 2018 and the Company expects to report the first data from the trial in calendar year 2019.
AIPAC Patient Recruitment Progressing
Having passed the midway point of recruitment for Immutep’s AIPAC Phase IIb clinical trial in Europe in June 2018, the Company is pleased to report that patient recruitment continues on track, with 126 patients (out of a planned 226 patients) now participating in the study. The recruitment is ongoing across Belgium, the Netherlands, Poland, Hungary, United Kingdom, France and Germany. First Progression-Free Survival data is expected in calendar year 2019.

Immutep’s alliance partner, GlaxoSmithKline (“GSK”), is continuing to progress the development of GSK2831781 (“GSK‘781”), a fully humanised monoclonal antibody derived from Immutep’s IMP731 antibody. GSK recently announced that the lead indication for GSK‘781 will be ulcerative colitis and anticipates that Proof of Concept data will be available in 2020.
