Immunicum Announces Publication in Journal for ImmunoTherapy of Cancer of Results Overview from Ilixadencel's First Clinical Study in Metastatic Renal Cell Carcinoma
Immunicum AB (publ; First North Premier: IMMU.ST), a biopharmaceutical company advancing a novel immuno-oncology treatment against a range of solid tumors, today announced that the results from the first clinical study of ilixadencel in patients with newly diagnosed metastatic renal cell carcinoma (mRCC) have been published in the Journal for ImmunoTherapy of Cancer. The results highlight ilixadencel's potential as a novel add-on, immune priming treatment for patients suffering from solid tumors based on its good safety profile and initial indications of prolonged survival. Ilixadencel, formerly known as INTUVAX, is currently in an ongoing Phase 2 trial in renal cell carcinoma (MERECA) as well as Phase 1/2 studies in hepatocellular cell carcinoma and gastrointestinal stromal tumors.
"This publication represents the complete analysis of data from the Phase 1/2 trial and we are pleased to have achieved peer reviewed publication in a well reputed international journal on all the elements of the trial. These data provided the rationale for the ongoing Phase 2 MERECA study," said Alex Karlsson-Parra, Chief Scientific Officer of Immunicum. "Even though the study has been formally completed in 2014, we are still following the patients and are pleased to report that as of May 2017, five out of 11 evaluable patients were still alive and the mean overall survival is clearly favourable compared to available historical data for the standard of care. One of the five patients still alive, experienced a complete regression of all brain and liver metastases, as noted in the publication. The patient has also demonstrated a nearly total regression of lung metastases and was metastasis-free following surgical removal of a small remaining lung metastasis at the end of 2016. Although this is only one case study, it is a promising initial result considering the expected poor prognosis for these patients."
The Phase 1/2, first-in-human study in twelve intermediate- and poor-risk patients with newly diagnosed mRCC investigated safety as a primary endpoint and reported on early signs of efficacy. The treatment regimen included two consecutive intratumoral injections of ilixadencel within 2 weeks followed by nephrectomy and subsequent standard of care. The study was initiated in January 2012 and formally completed in March 2014. Living patients are still followed to capture tumor response and survival data. The results published in the current issue of the Journal for ImmunoTherapy of Cancer represent a summary of the trial and the survival follow-up as of December 2016.
Ilixadencel showed a very good safety profile with no severe adverse events related to the treatment. Tumor-specific immune activation was indicated by intratumoral infiltration of CD8+ T cells and an increase in tumor-specific and interferon-gamma producing lymphocytes in peripheral blood. Median overall survival for the 11 evaluable mRCC patients was 42.5 months as of December 2016, which compares favourably with existing historical data. As of late May 2017, five of the patients that were enrolled in the study were still alive and a final median overall survival of 48.0 months was reached.
"Apart from the good safety profile, the data provided early indications that ilixadencel given in conjunction with sunitinib could have a potential synergistic antitumor effect, which we will be further investigating in the ongoing MERECA trial," commented Alex Karlsson-Parra, Chief Scientific Officer of Immunicum. "We believe that the future of cancer treatment lies in the rapidly evolving landscape of combination therapies and ilixadencel is uniquely positioned to become an integral part of modern combination regimens."
Carlos de Sousa, Chief Executive Officer of Immunicum added: "The publication represents the committment to our strategy to communicate data through peer review and therefore build validation for ilixadencel within the global scientific and medical community. We strongly believe in the potential of ilixadencel as an off-the-shelf immune primer in the treatment of solid tumors and are focused on advancing its clinical development to bring this therapy to patients."

About renal cell cancer / carcinoma
There are approximately 273,000 new cases of Renal Cell Cancer (RCC) diagnosed worldwide each year, representing approximately two percent of all cancers. The therapeutic effect of existing treatments, called directed therapies, is often of short duration, with limited survival rate gain. With no alternatives to these therapies, there exists a relatively large unsatisfied medical need for new treatments that are effective, more cost-efficient and have less unwanted side effects.
Ilixadencel cell therapy product (formerly known as INTUVAX®) is a cancer immune primer, developed for the treatment of solid tumors. Its active ingredient is activated allogeneic dendritic cells, derived from healthy blood donors. Intratumoral injection of these cells is expected to lead to an inflammatory response which in turn leads to tumor-specific activation of the patient's cytotoxic T-lymphocytes.
