"We are pleased that the wealth of data resulting from our completed Phase 3 study is now published in this international oncology journal," stated CEL-SCI’s Chief Scientific Officer, Dr. Eyal Talor. "We believe the marked improvement in quality of life offered by Multikine neoadjuvant treatment appeared to have had a positive impact on patients’ quality of life, and in addition to its favorable safety profile, tolerability and efficacy, it is likely to improve adoption rates for Multikine following regulatory approval."

The new, previously unpublished findings included the following patient quality of life data:

Quality of life (QoL) was assessed and validated through use of two instruments, EORTC QLQ-C30 and EORTC QLQ-H&N 35 across all clinical sites.
EORTC QLQ-C30 is a 30-item questionnaire developed by the European Organisation for Research and Treatment of Cancer (EORTC) to assess the health-related QoL of cancer patients.
EORTC QLQ-H&N 35 is a questionnaire designed to assess the QoL of head and neck cancer patients in conjunction with the general cancer-specific EORTC QLQ-C30.
QoL variables were assessed at baseline, before and after the Multikine treatment, and periodically during long-term follow up. These assessments included questions regarding pain in the mouth, jaw, and throat, problems swallowing, sense of smell and taste, ability for selfcare and mobility including walking, using the toilet, shortness of breath, emotional wellbeing including irritability and depression, and many other daily health assessment factors.
As a neoadjuvant therapy, patients were treated with Multikine before surgery. Pre-surgery objective early response to treatment with Multikine was confirmed by pathology at surgery. There were 45 objective early responders (which included 5 complete responders following 3-weeks of Multikine treatment) in the Multikine treated + standard of care group and zero (none reported by investigators) in the control group, which received the standard of care treatments only (i.e., surgery plus radiotherapy or surgery plus chemoradiotherapy; with cisplatin as the chemotherapeutic agent per the study protocol and NCCN Guidelines).
95.1% of complete responders to Multikine reported improved QoL
Complete responders reported a 100% (wherein all respondents scored the highest possible improvement from baseline) on 60% (39/65) of the QoL measures assessed including sleep, appetite, pain, emotional state, condition of mouth, sense of smell and taste, and social, family and public interactions.
QoL results for complete responders were measured and sustained for over 3 years following treatment with Multikine.
89.4% of partial responders to Multikine (those exhibiting greater than 30% reduction in tumor – confirmed by pathology at surgery) also reported improved assessed QoL measures from baseline.
About the Completed Phase 3 and Upcoming Confirmatory Registration Study

Based on the exceptional efficacy results and favorable safety profile for Multikine in a cohort of patients in the Phase 3 study, the U.S. Food and Drug Administration has given CEL-SCI the go ahead to initiate a confirmatory Registration Study of Multikine in newly diagnosed, previously untreated resectable stage 3 and 4 head and neck cancer patients who had no lymph node involvement and low PD-L1 tumor expression. There is a high unmet need in this patient population, for which no advancement in overall survival has been forthcoming in decades, despite many previous attempts by others.

Upon the Registration Study achieving full enrollment, CEL-SCI plans to seek early approval based on early tumor responses which were shown to correspond with survival rates. During the completed Phase 3 clinical trial, the 5-year overall survival rate of the target patient population (disease stage 3 and 4 patients who had no lymph node involvement and low PD-L1 tumor expression), which is the same population that will participate in the confirmatory study, increased to 73% when patients were treated with Multikine vs 45% for control patients who received only standard of care treatments.

OPM-101 is a first-in-class RIPK2 inhibitor administered orally, with the potential to treat several cancers. This milestone underscores OPM’s commitment to addressing significant unmet medical needs in oncology.

Globally, melanoma accounts for approximately 325,000 new cases and more than 57,000 deaths annually, with the highest incidences observed in regions such as Europe, North America, and Oceania. In Europe, the incidence of melanoma is rising, and there is an increasing focus on improving treatments for patients who develop resistance to immune checkpoint inhibitors (ICIs) like anti-CTLA4 and anti-PD1/PD-L1 therapies. Although ICIs have become a cornerstone of advanced melanoma treatment for several years, approximately 40-60% of patients experience resistance or progression, creating a pressing need for innovative therapeutic options.

In experimental cancer models, the addition of OPM-101 to anti-PD-1 antibody therapy has been shown to significantly enhance anti-tumor efficacy and promote greater sensitivity to PD-1 blockade, delaying or reducing loss of response to ICI therapy and demonstrating durable responses in preclinical models studied to date. The OPM team has shown that the underlying mechanisms of OPM-101 involve enhanced tumor antigen presentation and recognition, associated with remodelling of CD8+ T cell infiltration into the tumor stroma. Moreover, OPM-101 alone has also demonstrated significant antitumor activity based on its immunomodulatory properties.

REVERT Study Objectives and Design

This Phase 1b/2a clinical trial is an international, multicenter, open-label study designed to assess the safety and preliminary efficacy of OPM-101 in combination with pembrolizumab in metastatic melanoma patients treated with anti-PD-1 monotherapy or combination therapy (except with anti-LAG-3), and who have developed resistance to this treatment.

The trial will include around 45 patients at 10-13 sites in Switzerland, France, Italy and Spain, and will be conducted through two main phases:

Phase 1b: to assess the safety of OPM-101 in combination with pembrolizumab in patients who have developed resistance to this treatment by anti-PD1, and to select the recommended dose to be used in the second part of the study. This phase will involve a minimum of 6 patients.
Phase 2a: to assess the Disease Control Rate (DCR), safety and key biomarkers associated with immune response with the selected dose of OPM-101 in combination with pembrolizumab in patients who have developed resistance to anti-PD-1. This phase will be conducted on an expanded sample of around 35 patients.
The Phase 1b/2a study builds on the safety data from the Phase 1 study conducted in healthy volunteers (VS) in 2023-2024, which demonstrated a favorable safety profile for OPM-101 and robust pharmacokinetic and pharmacodynamic properties.

The results of Phase 1b will be used to determine the recommended dose for Phase 2a and to gather preliminary efficacy data on a limited number of patients. All data collected during this first phase will be reviewed and analyzed by an independent panel of experts forming the Data and Safety Monitoring Board (DSMB). During this open-label Phase 2a, efficacy data will be generated and reviewed on an ongoing basis, enabling trends in treatment efficacy to be identified before the interim analysis on the first 10 patients receiving the recommended dose and the final analysis on all patients. These efficacy data will be based on the analysis of images obtained for patient follow-up after 12 and 24 weeks of treatment, making it possible to define the Disease Control Rate (DCR) and the Objective Response Rate (ORR). In addition, circulating and tumor biomarkers of antitumor activity will be measured to document OPM-101’s mechanism of action.

The study is coordinated by Pr. Olivier Michielin, Head of the Precision Medicine Oncology Service and Head of the Department of Oncology at Geneva University Hospitals in Switzerland.

Phase 1b of the study will start at the same time in several hospitals in Switzerland. Submission of the application for authorization of the clinical study to the Swiss regulatory authorities (Swissmedic) and to the Ethics Committees of the centers involved in phase 1b of the study, was completed on March 24, 2025. The study is scheduled to start by July 2025.

For phase 2b, patients will be enrolled in additional centers in France, Italy and Spain. Submission of the application for clinical trial authorization in these selected European Union countries will take place in the 4th quarter of 2025, in order to obtain authorization to conduct the extension phase of the study, which could start in the first quarter of 2026.

Completion of this Phase 1b/2a clinical trial is expected by the end of 2027.

"In parallel with phase 1 VS, which enabled us to build a solid foundation around the PK/PD relationship of OPM-101 in humans, we have explored the antitumor activity of our compound alone and in combination with an anti-PD1 in mice. These preclinical results, reinforced by many recent international publications, have convinced us of its major potential in oncology, which is in fact the company’s primary mission.", said Philippe Genne, Chairman and CEO of Oncodesign Precision Medicine. "We are continuing to work on OPM-101’s innovative mechanism of action. In the current financial climate, this study is a major choice for OPM. We are also looking for a pharmaceutical partner to explore its potential in the treatment of IBD – Chronic Inflammatory Bowel Disease."

"Immunotherapy represents a real revolution for many patients suffering from many different types of cancer. This therapeutic approach is fundamentally changing the way we treat cancers by stimulating our immune system to attack and kill cancer cells. These approaches are the result of over a century of investigation and therapeutic advances. Immune checkpoint inhibitors (ICIs) such as anti-PD1s have been used for more than 10 years in several types of cancer, including melanoma and lung cancer. These therapies have proven highly effective with long-lasting responses, marking dramatic progress for many patients," added Jan Hoflack, Scientific Director of Oncodesign Precision Medicine. "Nevertheless, they come with a greater risk of toxicity including immune-related side effects, and a significant number of patients are or become resistant to these approaches. OPM-101, our RIPK2 inhibitor, has the potential to increase the response rate and reduce the side effects of these ICIs. This is what we will be evaluating in this Phase 1b/2a study in melanoma."

Prof. Olivier Michielin, Head of the Precision Oncology Service and Head of the Department of Oncology at the University Hospitals of Geneva, concluded: "Checkpoint inhibitors have revolutionized the management of melanoma. Despite high response rates in the advanced setting and clearly demonstrated long-term benefit, most patients progress under these treatments. Strategies to counteract the mechanisms of resistance to checkpoint inhibitors are therefore essential. OPM’s clinical trial is therefore extremely important, as it addresses exactly this population for whom we lack therapeutic options. What’s more, the prospect of being able to increase the efficacy of checkpoint inhibitors, while reducing toxicity, is of course extremely attractive and will be one of the hypotheses tested with OPM-101, as part of the study."

About OPM-101 in Oncology

OPM-101 is a first-in-class, potent, selective, orally available RIPK2 kinase inhibitor in oncology that has demonstrated the ability to maximize the immunogenicity of tumor cell death and activate a systemic anti-tumor immune response. Although initially linked to chronic inflammatory diseases, the RIPK2 pathway has been increasingly recognized since 2022 as a critical player in tumor progression. In preclinical studies, OPM-101 exhibited synergistic effects with anti-PD1 therapies, enhancing anti-tumor immunity and overcoming resistance in models treated with checkpoint inhibitors alone.

The ongoing Phase I trial (NCT06351904) is an open-label, multi-center study employing a standard 3+3 dose-escalation design. The primary objectives are to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of RAG-01. The study also assesses preliminary efficacy. As of the data cutoff date (December 15, 2024), nine patients had been enrolled across three dose cohorts: 30 mg, 100 mg, and 300 mg. The treatment regimen consists of a 6-week induction course of weekly instillations, followed by maintenance instillations at weeks 12, 24, 36, 48, and 72.

Key Findings Presented at EAU 2025

Excellent Safety Profile: No dose-limiting toxicities (DLTs) were observed at any of the dose levels evaluated. Treatment-related adverse events (AEs) were reported in 88.9% (8/9) of patients, but all were Grade 2 or lower in severity. The most frequently reported AEs (each occurring in 11.1% of patients) were urinary urgency, increased urinary frequency, and urinary tract infection.
Targeted Drug Delivery and Activity: PK analysis revealed minimal systemic exposure of RAG-01, confirming the effectiveness of the intravesical administration and LiCO technology. Dose-dependent increases in RAG-01 urine concentrations were observed, ranging from 83.3 to 1,820 µg/ml at 2 hours post-instillation. Importantly, a dose-dependent increase in p21-positive urothelial cells was observed, confirming successful target engagement and on-mechanism activity of RAG-01.
Remarkable Early Efficacy: In patients with carcinoma in situ (CIS), the complete response (CR) rate was 66.7% (2/3 patients). Furthermore, 66.7% (2/3) of patients with papillary tumors remained disease-free at the 3-month assessment. These promising efficacy signals were observed in the two lowest dose cohorts (30 mg and 100 mg), highlighting the potential of RAG-01 even at early stages of clinical development.
"These preliminary findings are incredibly exciting and validate the potential of our saRNA platform to address significant unmet needs in oncology," said Dr. Long-Cheng Li, CEO of Ractigen Therapeutics. "Achieving such a high complete response rate in the lowest dose cohorts, with a favorable safety profile, is a testament to the innovative science behind RAG-01 and its potential to become a transformative therapy for patients with BCG-unresponsive NMIBC."

Dr. Paul Anderson, the investigator of The Royal Melbourne Hospital, stated, "The striking CR rates observed in these early cohorts are highly encouraging, particularly for BCG-unresponsive NMIBC patients who currently have limited treatment options. These results pave the way for further exploration of RAG-01’s capabilities in this challenging disease."

Next Steps

Ractigen Therapeutics plans to advance the RAG-01 clinical program by continuing dose escalation and initiating dose-expansion cohorts to further evaluate the therapy’s safety, efficacy and determine the optimal dose. The company is committed to rapidly progressing RAG-01 through clinical development, with the goal of providing a groundbreaking new treatment option for patients with NMIBC.

About NMIBC

Non-muscle invasive bladder cancer (NMIBC) is a common malignancy confined to the lining of the bladder. The standard first-line treatment is transurethral resection of the bladder tumor (TURBT) followed by intravesical BCG immunotherapy. However, a significant proportion of patients experience recurrence or become unresponsive to BCG, highlighting the need for new and effective treatment options.

About RNAa

RNAa is a clinically validated platform technology, pioneered by Dr. Long-Cheng Li and his team, that harnesses the power of small activating RNAs (saRNAs). saRNAs are double-stranded RNA oligonucleotides that target specific gene regulatory regions to selectively activate gene expression, restoring the production of therapeutic proteins. This innovative technology has broad therapeutic potential across a range of diseases, particularly where traditional therapeutic approaches have proven insufficient, including genetic disorders and cancers.
