Gothenburg, April 10, 2025 – Elicera Therapeutics AB (publ), a clinical stage cell and gene therapy company developing next generation cancer treatments based on oncolytic viruses and CAR T-cell therapies, armed with immune-activating properties via the company’s commercially available iTANK platform, today announced that the Data Safety and Monitoring Board (DSMB) has completed its first assessment of the ongoing Phase I/IIa CARMA clinical trial with the CAR T-cell therapy ELC-301 for the treatment of B-cell lymphoma. The DMSB recommended that the study continue as planned. The dose-escalation study, conducted in collaboration with Uppsala University as sponsor, previously reported a complete response (no detectable tumor) in the first treated patient at the initial follow-up one month after completing treatment, with no serious adverse events observed. Two additional patients have since been treated at the lowest dose level in the first dosing group (cohort 1). Elicera intends to report preliminary results from the study as each dosing cohort is completed. Preliminary efficacy data from the first cohort is expected to be presented at the 7th Swedish Cancer Research Meeting in Malmö on May 22. Following the DSMB’s recommendation to proceed, treatment of patients in the second cohort at next dose level can now begin.

The study is divided into a dose-escalation phase (phase I) and a dose-expansion phase (phase IIa). Phase I primarily aims to establish the optimal dose and safety profile in up to 12 patients, while phase IIa will further evaluate the efficacy of the maximum tolerated dose in an additional six patients. Phase I is planned to include three cohorts (dosing groups), with three patients in the first and second cohorts, and six patients in the third dcohort, who are expected to receive the maximum tolerated dose. The CARMA study is being conducted at Uppsala University Hospital and Karolinska University Hospital in Huddinge. About ELC-301 ELC-301 is a fourth-generation CAR T-cell therapy targeting the CD20 antigen, armed with the company’s iTANK platform to activate a broader and more comprehensive parallel immune response against cancer. CAR T-cells are a form of cell therapy created by genetically modifying a patient’s T-cells to express a synthetic receptor (chimeric antigen receptor, CAR). This receptor is specifically designed to target a single tumor antigen—a molecule visible on the surface of cancer cells—and enables the T-cells to locate, bind to, and destroy the cancer cells. About the iTANK platform The iTANK technology platform has been developed for arming and enhancing CAR T-cells to meet two of the major challenges CAR T-cell therapies face in the treatment of solid tumors: a very diverse set of tumor antigen targets and a very hostile tumor microenvironment. The technology is used to incorporate a transgene into CAR T-cells encoding a neutrophil activating bacterial protein (NAP). NAP secreted from the CAR(NAP) T-cells has been shown to be able to enhance the function of CAR T-cells and importantly activating a parallel bystander immune response against the cancer via CD8+ killer T-cells. This is expected to lead to a broad attack against most antigen targets on cancer cells. The iTANK platform is used to enhance the company’s own CAR T-cells but can also be universally applied to other CAR T-cell therapies under development. Proof-of-concept data was published in Nature Biomedical Engineering in April 2022.

More information about iTANK platform is available here: https://www.elicera.com/technology About Elicera Therapeutics AB Elicera Therapeutics AB (publ) has developed the patented gene technology platform iTANK that enables the arming of new and existing CAR T-cell therapies targeting aggressive and relapsing cancer forms. Elicera Therapeutics thereby addresses a well-defined and vast market. The company’s CAR T-cell therapies have shown a potent effect toward solid tumors which are recognized as particularly difficult to treat and constitute the majority of cancer cases. The company addresses a global multibillion market in cell therapy through its offering of non-exclusive licensing of the iTANK-platform to companies in the pharmaceutical industry. Elicera Therapeutics has four internal development projects in immune therapy that separately have the potential to generate substantial value through exclusive out-licensing agreements.

Gothenburg, April 4, 2025 – Elicera Therapeutics AB (publ), a clinical stage cell and gene therapy company developing next generation cancer treatments based on its proprietary commercial technology platform iTANK, today announced that the company’s Chief Scientific Officer, Professor Magnus Essand, has been invited to speak at the Swedish Cancer Research Meeting (SCRM) 2025 in Malmö on May 22. SCRM is Sweden’s largest cancer research meeting, held every other year, where prominent international researchers are also invited. At SCRM2025, leading representatives from academia, healthcare, and industry will gather to exchange knowledge, present new research findings, and foster collaboration. The goal is to strengthen Sweden’s cancer research ecosystem and create the conditions for joint efforts that can lead to improved treatments and a deeper understanding of cancer. Magnus Essand, one of the co-founders of Elicera Therapeutics and Professor of Gene Therapy at Uppsala University, will participate as a speaker at SCRM2025. His presentation, titled "Novel cell and gene therapies for the treatment of cancer – The Uppsala experience", will highlight the company’s progress in developing novel cell and gene therapies for cancer treatment. During his talk, Professor Essand will present Elicera Therapeutics’ CAR T-cell program and the company’s proprietary platform technology, iTANK, which is used to arm CAR T-cells to trigger a broad immune activation against cancer. He will also present preliminary efficacy data from cohort 1 of the ongoing CARMA study, which evaluates the safety and efficacy of ELC-301 – the company’s iTANK-armed CAR T-cell therapy targeting B-cell lymphoma. In light of this, Elicera has decided not to present the cohort 1 data at the ISCT conference, in order to generate greater impact at SCRM2025. This decision also enables the inclusion of data from a longer follow-up period, which is expected to provide a more informative and valuable data set.

LUND, Sweden, March 18, 2025 /PRNewswire/ -- Oncorena is pleased to announce that the FDA has approved the Company's IND application to initiate the Phase I/II study Oncorella-1: A Phase 1/2, open label, single arm study on safety, tolerability and anti-tumor efficacy of orellanine treatment in patients with metastatic clear-cell or papillary renal cell carcinoma (NCT05287945, ONC001-CL-001). In the study Oncorella-1, up to 75 patients with severe metastatic renal cancer requiring dialysis will be enrolled. These patients have exhausted their treatment options and ONC175 represents a potentially new first-in-class treatment for patients with urgent unmet medical need. The study is currently being conducted at Karolinska University Hospital in Stockholm, Sweden. Börje Haraldsson, CEO & co-founder of Oncorena comments: "This approval brings us closer to being able to evaluate the potential for this novel treatment in patients in desperate need for new and better options. We are excited to start the first US site, MD Andersson in Houston, Texas, where the study will be led by investigator Professor Nizar Tannir, a world-leading expert in renal cancer." About ONC175 ONC175 is an investigational drug product under development that contains synthetically produced orellanine as active ingredient. Orellanine is highly specific to the kidney and induces irreversible renal failure. It is clinically well-known that orellanine does not affect organs other than the kidneys. In pioneering preclinical studies ONC175 demonstrated a powerful and highly organ-specific mode of action capable of eradicating human metastatic renal cancer cells. The primary goal is to develop ONC175 as a potential curative treatment of metastatic renal cell carcinoma in patients with no remaining kidney function, i.e., patients on dialysis. About kidney cancer Approximately 400,000 patients are affected by kidney cancer globally according to the WHO. The disease can often be cured by surgery if detected early, but the prognosis is less favorable if there are metastases. Today, the disease is treated with various types of targeted and immuno-active drugs, that seldom are curative. There is therefore a great and urgent unmet medical need for new, effective and safe drugs.
