INSIGHT-004 Clinical Trial Update
December 19th 2019
- Recruitment commenced for second cohort of 6 patients at higher efti dose combined with avelumab
- No new safety signals in the first cohort, with 1 patient reporting a partial response
- More data expected to be reported in H1 CY2020
SYDNEY, Australia, Dec. 19, 2019 (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 update on the INSIGHT-004 Phase I clinical trial to evaluate the combination of eftilagimod alpha (“efti” or “IMP321”) with avelumab, a human anti-PD-L1 antibody, in patients with advanced solid malignancies.
Following full recruitment of the first cohort of 6 patients receiving avelumab (standard dose) and efti (6 mg), Immutep’s partner IKF has now commenced the recruitment of patients into the second cohort (standard dose avelumab, with 30 mg efti) which will involve also 6 participants.
No new safety signals or dose limiting toxicities have been reported from the first cohort of patients. The observed safety profile also aligns with the known safety profile of the monotherapies.
Participants enrolled in this trial are patients with late-stage cancer who have been heavily pre-treated for advanced, metastatic solid tumors. Typically, they have no other therapy options available. Out of 6 patients, 1 patient experienced a partial response according to RECIST 1.1.
More data from the study is expected to be reported in H1 CY2020.
Prof. Dr. Salah-Eddin Al-Batran, lead investigator of INSIGHT-004 commented: “We are really pleased that INSIGHT-004 recruitment is advancing and that we can start to enroll the second cohort of 6 patients. The treatment’s safety profile is consistent with previous trials of efti which is encouraging and it’s also good to see early activity signals with one patient reporting a partial response already.”
INSIGHT-004 is the fourth arm of the INSIGHT trial which is being conducted by Institute of Clinical Cancer Research, Krankenhaus Nordwest GmbH in Frankfurt, Germany (IKF). It is being conducted under Immutep’s collaboration with Merck KGaA, Darmstadt, Germany and Pfizer Inc and is evaluating the safety, tolerability and recommended Phase II dose of Immutep’s lead immunotherapy product candidate efti when given in combination with avelumab in 12 patients with advanced solid malignancies.
INSIGHT-004 is being conducted as an amendment to the ongoing INSIGHT Phase I clinical trial. The Institute of Clinical Cancer Research, Krankenhaus Nordwest GmbH in Frankfurt, Germany (“IKF”) is the sponsor of the clinical trial which is being conducted under the existing protocol of the ongoing INSIGHT clinical study. Prof. Dr. Salah-Eddin Al-Batran, the lead investigator of INSIGHT and member of Immutep’s clinical advisory board, is the lead investigator of INSIGHT-004.

Avelumab Approved Indications
Avelumab (BAVENCIO®) in combination with axitinib is indicated in the US for the first-line treatment of patients with advanced renal cell carcinoma (RCC).
The US Food and Drug Administration (FDA) also granted accelerated approval for avelumab (BAVENCIO®) for the treatment of (i) adults and pediatric patients 12 years and older with metastatic Merkel cell carcinoma (mMCC) and (ii) patients with locally advanced or metastatic urothelial carcinoma (mUC) who have disease progression during or following platinum-containing chemotherapy, or have disease progression within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy. These indications are approved under accelerated approval based on tumor response rate and duration of response. Continued approval for these indications may be contingent upon verification and description of clinical benefit in confirmatory trials.
Avelumab is currently approved for patients with MCC in 50 countries globally, with the majority of these approvals in a broad indication that is not limited to a specific line of treatment.
Avelumab Important Safety Information from the US FDA-Approved Label
The warnings and precautions for avelumab (BAVENCIO®) include immune-mediated adverse reactions (such as pneumonitis and hepatitis [including fatal cases], colitis, endocrinopathies, nephritis and renal dysfunction and other adverse reactions [which can be severe and have included fatal cases]), infusion-related reactions, hepatotoxicity, major adverse cardiovascular events (MACE) [which can be severe and have included fatal cases], and embryo-fetal toxicity.
Common adverse reactions (reported in at least 20% of patients) in patients treated with BAVENCIO® monotherapy include fatigue, musculoskeletal pain, diarrhea, nausea, infusion-related reaction, peripheral edema, decreased appetite/hypophagia, urinary tract infection and rash. Common adverse reactions (reported in at least 20% of patients) in patients receiving BAVENCIO® in combination with axitinib include diarrhea, fatigue, hypertension, musculoskeletal pain, nausea, mucositis, palmar-plantar erythrodysesthesia, dysphonia, decreased appetite, hypothyroidism, rash, hepatotoxicity, cough, dyspnea, abdominal pain and headache. Clinical chemistry and hematology laboratory value abnormalities reported in at least 10% of patients include hyponatremia, lymphopenia, GGT increased, blood triglyceride increased and lipase increased, and grade 3-4 lymphopenia, anemia, elevated cholesterol and liver enzymes.
