IMM-101 Trials

Immodulon is committed to a rigorous programme of clinical trials and pre-clinical studies for its lead product, IMM‑101, in the treatment of various forms of cancer, in combination with other anti-cancer treatments. Clinical studies to date have indicated that IMM‑101 is well tolerated and have produced encouraging increases in surivial for patients with pancreatic cancer and advanced melonoma.

IMM‑101 Phase I

In 2010, IMM‑101 was evaluated in a Phase I trial (a trial which tests what a drug does to a patient’s body and how well it is tolerated), enrolling 18 patients with advanced melanoma where the disease had spread to the patient’s other organs. Historically only approximately 10% of patients survive 5 years with this condition. However, in an extension to this Phase 1 trial, six patients receiving IMM‑101 were still alive more than five years later. This 5-year survival rate of 33% compares favourably with historical data.

The initial paper on the Phase I study was published in the Annals of Oncology (Oxford Journals) 2011: Stebbing J. et al. An intra-patient placebo-controlled phase I trial to evaluate the safety and tolerability of intradermal IMM‑101 in melanoma which describes the initial safety and tolerability data.

These long term follow up results were presented at the international European Society of Medical Oncology (ESMO) meeting in Lausanne in November 2015 and some patients are still in a follow up study.

IMM‑101 Phase II

In 2013, IMAGE-1, a Phase II proof-of-concept study of 110 patients with locally advanced or metastatic pancreatic cancer was initiated. Patients were given the chemotherapy drug gemcitabine with and without IMM‑101. The study was designed to provide indicative rather than definitive efficacy results, but exceeded expectations by providing promising overall survival results and durable responses in all prospectively defined populations as well as a favourable safety profile.

Kaplan Meier (KM) survival curves for the ITT population with metastatic disease.

The graph shows the Kaplan Meier (KM) survival curves for the Intention-to-Treat (ITT) population with metastatic disease where an increase in median survival of 2.6 months corresponds to a 59% increase in survival for patients receiving IMM‑101 + gemcitabine compared to gemcitabine alone. Equally importantly, the continued separation of the KM curves to 24 months and the survival outcomes at 12, 18 and 24 months indicate a long lasting response for some patients with this devastating disease. Safety analysis indicated no additional burden of side-effects in adding IMM‑101 to gemcitabine. IMM‑101 is gentle to the body and does not add a further burden on the patient’s health and quality of life. Side effects were limited to swelling and itching where the injection is administered, similar to a BCG injection.
