Immutep doses First Patient in TACTI-002 Phase II Trial
March 6th 2019
- The First Patient has been dosed at “START Madrid- FJD” in Spain
- Clinical trial sites are active and more will be activated and commence recruitment in coming months
SYDNEY, Australia, March 06, 2019 (GLOBE NEWSWIRE) -- Immutep Limited (ASX: IMM; NASDAQ: IMMP) ("Immutep” or “the Company”), announces the first patient has been dosed with the combination of Keytruda® and efti for TACTI-002, a Phase II clinical study.
TACTI-002 (Two ACTive Immunotherapies) is being conducted in collaboration with Merck & Co., Inc., Kenilworth, NJ, USA (known as “MSD” outside the United States and Canada). The study will evaluate the combination of Immutep’s lead product candidate eftilagimod alpha (“efti” or “IMP321”) with MSD’s KEYTRUDA® (or pembrolizumab, a PD-1 blocking antibody) in up to 109 patients with second line head and neck squamous cell carcinoma or non-small cell lung cancer in first and second line. The study will take place in up to 13 study centres across the U.S., Europe and Australia.
Recruitment for the trial commenced at 2 sites in Australia, 1 site in the US, 4 sites in Europe. Four further clinical trial sites are expected to initiate and commence recruitment in the coming months.
Immutep CSO and CMO, Dr Frederic Triebel, said: “Dosing the first patient of our TACTI-002 Phase II clinical study is an important milestone. The interim data reported so far from our TACTI-mel Phase I study in melanoma has shown that the combination of efti with pembrolizumab, a PD-1 blocking antibody, is delivering long lasting and durable responses. Given that the TACTI-002 study leverages the same combination therapy, we are hopeful that it will be beneficial for patients with head and neck squamous cell carcinoma or non-small cell lung cancer.”

Objectives | Primary Objective
|
Study Design | |
Planned Sample Size | Up to 109 patients |
Study Population | Key inclusion criteria 1. Part A (1st line, PD-X naïve NSCLC): histologically- or cytologically-confirmed diagnosis of non-small cell lung carcinoma stage IIIB not amenable to curative treatment or stage IV not amenable to EGFR/ALK based therapy, treatment naïve for systemic therapy given for advanced/metastatic disease (previous palliative radiotherapy for advanced/metastatic disease acceptable) Part B (2nd line, PD-X refractory NSCLC): histologically- or cytologically-confirmed diagnosis of NSCLC after failure of first-line treatment (for metastatic disease) with at least 2 cycles of any PD-1/PD-L1 containing based therapy (i.e. nivolumab, pembrolizumab, avelumab, durvulumab, etc) alone, or in combination with any other immunotherapeutic or chemotherapy. Part C (2nd line PD-X naive HNSCC): Histologically- or cytologically-confirmed recurrent disease not amenable to curative treatment with local or systemic therapy, or metastatic (disseminated) HNSCC of the oral cavity, oropharynx, hypopharynx, and larynx that is considered incurable by local therapies after failure of prior platinum-based therapy. 2. Submission of formalin-fixed diagnostic tumor tissue 3. ECOG performance status 0-1. 4. Expected survival > 3 months. Key exclusion criteria 1. For part A (1st line, PD-X naïve NSCLC):
3. Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti PD L2 agent or with an agent directed to another stimulatory or co-inhibitory T-cell receptor (e.g., CTLA-4, OX 40, CD137) and was discontinued from that treatment due to a Grade 3 or higher irAE (Part B only) 4. Has received prior chemotherapy, anti-cancer monoclonal antibody, major surgery, another systemic cancer therapy or has participated in a study of an investigational agent or has used an investigational device within 4 weeks prior to cycle 1 day 1. Note: Patients must have recovered from all AEs due to previous therapies to ≤Grade 1 or baseline. Patients with ≤Grade 2 neuropathy, alopecia and elevated transaminases in case of liver metastases may be eligible. If patient received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting study treatment. Participants who have entered the follow-up phase of an investigational study may participate as long as it has been 4 weeks after the last dose of the previous investigational agent. 5. Known active central nervous system metastasis and/or carcinomatous meningitis. Patients with previously treated brain metastases may participate provided they are radiologically stable: i.e. without evidence of progression for at least 4 weeks by repeat imaging, clinically stable and without requirement for steroid treatment for at least 14 days prior to cycle 1 day 1. 6. Receives continuous systemic treatment with either corticosteroids (>10 mg daily prednisone equivalents) or other immunosuppressive medications within 7 days prior to cycle 1 day 1. Inhaled or topical steroids and physiological replacement doses of up to 10 mg daily prednisone equivalents are permitted in the absence of active auto-immune disease. |
