Immunicum AB (publ) Announces Positive Phase II MERECA Topline Results Including Complete Tumor Responses in Metastatic Renal Cell Carcinoma Patients
“As a clinical oncologist specialized in treating kidney cancer patients, the prospect of an immune primer that can support the achievement of complete responses in advanced-stage patients with a positive tolerability and safety profile is extremely exciting, especially in an indication in which complete responses are rare,” commented Dr. Magnus Lindskog, Associate Professor at Uppsala University Hospital and MERECA investigator. “If this response rate can be confirmed in a larger pivotal trial, it would represent a major step forward for the treatment of kidney cancer patients.”

Background on the Clinical Development of MERECA:
Phase I/II Clinical Trial
The Phase I/II of the study was initiated in 2012 and included twelve patients with newly diagnosed metastatic renal cell carcinoma (mRCC). The last patient was treated in August 2013 and in March 2014 the concluding report was presented. No treatment-related serious adverse events had been noted. The immunology data showed clear signs of tumor specific immune activation. The study showed strong infiltration of CD8+ T cells in the treated tumors, but also in distant metastasis, which indicates that the activated immune system is also able to identify and target cancer cells in other parts of the body after injection of ilixadencel.
Follow-Up Data Published in Journal for ImmunoTherapy of Cancer
Immunicum published follow-up data from the Phase I/II study in the Journal for ImmunoTherapy of Cancer in June 2017, which contained data of patients up to December 2016. Updated survival time data, as per January 2018, from the Phase I/II study, showed that three out of eleven evaluable patients were alive. Three out of eleven evaluable patients surpassed the 5-year survival and the median overall survival time for the patient group as a whole was 48 months compared to the expected median survival time of 14 – 16 months based on historical data of newly diagnosed metastatic patients being treated with tyrosine kinase inhibitors, including Sutent® (sunitinib) and Votrient® (pazopanib). For the six patients with a poor prognosis (MSKCC high risk), the median overall survival time was 36 months, compared to the expected 9 months based on historical control.
Phase IIa Clinical Trial
MERECA is an exploratory, international, randomized, controlled and open-label Phase II clinical trial in which a total of 88 newly diagnosed, intermediate and poor-prognosis metastatic renal cancer patients were enrolled. The primary objectives of the study were to evaluate median overall survival (OS) and 18-month survival rates. Based on a 2-to-1 randomization, patients received either two intratumoral doses of ilixadencel before nephrectomy (surgical removal of the tumor-affected kidney) and subsequent treatment with sunitinib or sunitinib therapy alone post-nephrectomy. Secondary objectives included evaluation of safety and tolerability, tumor response and immunological profiling including T cell infiltration.
The primary purpose of the MERECA study was to investigate the clinical efficacy of treatment with ilixadencel in combination with sunitinib in newly diagnosed metastatic renal cell cancer patients. This Phase II study is primarily a proof of concept study and it will provide crucial input for planning of future pivotal/confirmatory (i.e. Phase III) trials. In December 2016, Immunicum received clearance from FDA on its Investigational New Drug (IND) application and expanded the MERECA study into the US in the second quarter of 2017, which led to the first patient enrolled in August 2017. The last patient was recruited to the study in early 2018.
