Ultimovacs' New Findings on UV1 Vaccine for Mesothelioma

Ultimovacs Presents Updated Findings on UV1 Vaccine Trial

Oslo: Ultimovacs ASA (OSE: ULTI), a biotechnology company at the forefront of developing innovative immunotherapies for cancer, has announced intriguing results concerning its UV1 Phase II NIPU trial. The updated data analysis was shared during the highly acclaimed ESMO 2024 Congress, held in Barcelona. This trial is significant as it explores the effectiveness of UV1, a telomerase vaccine, when combined with traditional immunotherapy medications ipilimumab and nivolumab for patients suffering from inoperable malignant pleural mesothelioma.

Significant Clinical Insights from the NIPU Trial

Initially reported at ESMO 2023, it was noted that the trial did not meet the primary endpoint of improved progression-free survival (PFS) according to blinded, independent central review (BICR). However, crucial secondary endpoints revealed promising outcomes, including an objective response rate (ORR) that doubled and a notable 27% reduction in the risk of death.

Enhanced Outcomes for Epithelioid Subgroup

During this year's congress, Ultimovacs highlighted a particular improvement noted in patients belonging to the epithelioid subgroup, which makes up around 70% of mesothelioma cases. For this group, the trial demonstrated an impressive 5.5-month enhancement in median PFS when UV1 was used in conjunction with ipilimumab and nivolumab, compared to a mere 2.9 months with these immunotherapies alone.

Presentation Details and Next Steps

The complete results from this study were elaborated in a poster at the congress. The anticipated abstract detailing these findings will soon be accessible on Ultimovacs' official website. This ongoing research underscores Ultimovacs’ commitment to addressing significant unmet medical needs for mesothelioma patients.

Expert Insights on the Research

Jens Bjørheim, Chief Medical Officer at Ultimovacs, remarked on the potential implications of these results, indicating strong reasons for continued exploration of UV1 in treating this challenging condition. Ultimovacs aims to offer new hopes where current treatments fall short, and they plan to discuss these findings with the broader medical community to gauge future strategies.

About the NIPU Trial

The NIPU trial, a randomized, open-label, multi-center Phase II study initiated by investigators and supported by Oslo University Hospital, Bristol-Myers Squibb, and Ultimovacs, included a total of 118 patients across six hospitals in various countries. The objective was to deliver enhanced treatment options through the UV1 vaccine alongside established immunotherapies.

In the trial, patients were equally divided into two groups: both groups received standard treatment with nivolumab and ipilimumab while the experimental group also received the UV1 vaccine. This cohort was anticipated to experience significant clinical advantages compared to those receiving the standard treatment alone.

About the UV1 Vaccine

UV1 is designed to provoke a targeted immune response against telomerase, a key protein found in many cancer cells. The formulation consists of synthetic peptides aimed at inducing immune cells critical for combating tumors. This promising vaccine does not necessitate prior HLA screening, making it potentially available for a wider patient population.

Ultimovacs' Broader Vision and Development

As a clinical-stage firm, Ultimovacs is actively pursuing a comprehensive clinical development program. This involves five Phase II trials across various cancer types, enrolling over 750 patients worldwide. The outcomes from the NIPU trial could potentially pave the way for broader applications of UV1 and similar innovative therapies, reinforcing Ultimovacs’ vision of transforming cancer treatment.
