Ultimovacs Announces Topline Results from INITIUM Study Evaluating UV1 Vaccination Added to Ipilimumab and Nivolumab in Patients with Unresectable or Metastatic Malignant Melanoma
Ultimovacs Announces Topline Results from INITIUM Study Evaluating UV1 Vaccination Added to Ipilimumab and Nivolumab in Patients with Unresectable or Metastatic Malignant Melanoma
* With the 18-month minimum follow-up of the patients in the INITIUM trial,
the trial did not meet the primary endpoint of prolonging progression-free
survival (PFS). Median PFS was not reached in either arm. Evaluation of
secondary endpoints did not show a difference in overall survival and
objective response rate between the treatment and control arms
* UV1 maintained its positive safety profile with similar safety and
tolerability as observed in the control arm
* Ultimovacs remains confident in the potential of the UV1 vaccine and its
promise in specific therapeutic combinations and indications
* Upcoming data from the FOCUS Phase II trial and overall survival updates
from the NIPU Phase II trial will be the next important data points for the
further assessment of UV1
* Cash preservation initiatives will be implemented to ensure that the
available financial resources will sustain the company into 2025, enabling
the achievement of upcoming key inflection points.
Oslo, March 7 2024: Ultimovacs ASA ("Ultimovacs") (OSE ULTI), a clinical-stage
biotechnology leader in novel immunotherapeutic cancer vaccines, today announced
topline results from the Phase II clinical trial, INITIUM (NCT04382664
(https://clinicaltrials.gov/study/NCT04382664?term=ultimovacs&rank=2)),
evaluating the company's therapeutic cancer vaccine candidate UV1 as first-line
treatment in unresectable or metastatic malignant melanoma.
The study's primary endpoint was to investigate progression-free survival (PFS)
in the experimental arm (UV1 plus treatment with checkpoint inhibitors (CPIs)
ipilimumab and nivolumab) as compared to the control arm (ipilimumab and
nivolumab alone). Secondary endpoints included overall survival (OS), objective
response rate (ORR) as well as duration of response (DOR) and safety. Topline
data demonstrated that the combined treatment of UV1 with ipilimumab and
nivolumab showed similar clinical benefits as treatment with ipilimumab and
nivolumab alone, meaning the primary and secondary endpoints of the study were
not met.
With the 18-month minimum follow-up of the patients in the trial, the median PFS
was not reached in either arm, and the Hazard Ratio (HR) between the arms for
PFS was 0.95. Evaluation of secondary endpoints did not show a difference in
overall survival and objective response rate between the arms. UV1 maintained a
positive safety and tolerability profile.
Ultimovacs will further analyze the full data set while continuing to advance
its ongoing Phase II trials for UV1.
"Ultimovacs had set a very high bar for UV1 by comparing it to the ipilimumab
and nivolumab combination, currently considered the most effective treatment for
this patient population. Nevertheless, we are disappointed that UV1 did not add
further clinical benefit for these late-stage melanoma patients in the INITIUM
trial. Looking forward, our first objective is to complete the analysis of the
full data set in depth to gain further insights on UV1's effects," said Jens
Bjørheim, Chief Medical Officer, Ultimovacs. "We wish to thank the patients for
their trust and the investigators for their collaboration with us."
"We have seen signals in previous trials that UV1 has the ability to show
positive effects in cancer patients. We remain committed to UV1, and we look
forward to thoroughly examining the INITIUM data, receiving the FOCUS data, and
updated NIPU survival data over the next several months. Our objective is to
define the best path forward for our development strategy for UV1," said Carlos
de Sousa, Chief Executive Officer, Ultimovacs.
Ultimovacs is evaluating the universal cancer vaccine UV1 in a broad clinical
development program across various cancer indications with different biology and
disease stages, in combination with different checkpoint inhibitors. The topline
data from INITIUM is the second readout among the five randomized trials in the
UV1 Phase II clinical program. In October 2023, the UV1 Phase II trial NIPU in
malignant mesothelioma reported a clinically meaningful overall survival benefit
in the patients receiving UV1 vaccination on top of ipilimumab and nivolumab
compared to ipilimumab and nivolumab alone, with no added toxicities. Per
protocol, the overall survival results were statistically significant. In
addition to the studies in malignant melanoma and malignant mesothelioma, Phase
II studies are ongoing in patients with head and neck cancer (FOCUS), ovarian
cancer (DOVACC), and non-small cell lung cancer (LUNGVAC). The data from the
FOCUS trial is expected in the third quarter of 2024.
The Company will host a webcast presentation and discussion of the results from
the INITIUM study on Thursday, March 7 2024 at 08:00 (CET). Link to the webcast

About Ultimovacs
Ultimovacs is a clinical-stage biotechnology leader in novel immunotherapeutic
cancer vaccines with broad applicability. Ultimovacs' lead cancer vaccine
candidate UV1 is directed against human telomerase (hTERT) an antigen which is
present in 85-90% of cancers in all stages of tumor growth. A broad clinical
program, with Phase II trials in five cancer indications enrolling more than
670 patients, aims to demonstrate UV1's impact in combination with other
immunotherapies in multiple cancer types expressing telomerase and where
patients have unmet medical needs. UV1 is universal, off-the-shelf and easy to
use, and is a patented technology owned by Ultimovacs.
In addition, Ultimovacs holds all rights of the proprietary TET technology
platform for any possible future use of formulations in various solid tumor
indications. The Company is listed on Euronext Oslo Stock Exchange (ULTI.OL).
About INITIUM
INITIUM is an Ultimovacs-sponsored randomized, comparative, multicenter Phase II
trial in which the universal cancer vaccine UV1 will be evaluated in combination
with the checkpoint inhibitors ipilimumab and nivolumab for first-line treatment
of patients with unresectable or metastatic malignant melanoma. The first
patient received treatment in the INITIUM trial in June 2020, and the last
patient was enrolled in July 2022. The study is being conducted at 39 hospitals
across the U.S., U.K., Belgium, and Norway. The initial study design called for
enrollment of 154 patients. Two additional patients were enrolled bringing the
total number of patients in the study to 156.
About the UV1 Phase II program
The immunotherapeutic cancer vaccine UV1 is investigated in combination with
checkpoint inhibitors in patients with various cancer indications with diverse
tumor biology. The diversity of the UV1 Phase II program places Ultimovacs in a
favorable position to capture the cancer vaccine's potential broad applicability
when combined with checkpoint inhibitors:
* INITIUM: Evaluating UV1 in combination with ipilimumab and nivolumab as
first-line treatment for patients with malignant melanoma. Enrollment of
156 patients completed in July 2022. Sponsored by Ultimovacs.
* NIPU: Evaluating UV1 in combination with ipilimumab and nivolumab as second-
line treatment for patients with malignant pleural mesothelioma. Enrollment
of 118 patients completed in January 2023. Data presented at the ESMO
Congress in October 2023, showed that UV1 as add-on to ipilimumab and
nivolumab, demonstrated a statistically significant and clinically
meaningful improvement of overall survival versus ipilimumab and nivolumab
alone. 31% of the patients receiving UV1 vaccine experienced an objective
response, compared to 16% in the control arm. The investigator-initiated
study is led by Oslo University Hospital and supported by Bristol-Myers
Squibb and Ultimovacs.
* FOCUS: Evaluating UV1 in combination with pembrolizumab as first-line
treatment for patients with head and neck cancer. Enrollment of 75 patients
completed in August 2023, expected readout Q3 2024. The investigator-
initiated study is led by Halle University in Germany, supported by
Ultimovacs.
* DOVACC: Evaluating UV1 in combination with olaparib and durvalumab as
maintenance therapy in non-BRCA mutated patients with advanced ovarian
cancer. 75 of 184 patients enrolled as of Q4 2023 reporting, expected
readout H1 2025. The investigator-initiated study is led by NSGO-CTU and
supported by ENGOT, AstraZeneca, and Ultimovacs.
* LUNGVAC: Evaluating UV1 combined with cemiplimab as first-line treatment of
non-small cell lung cancer patients. 23 of 138 patients enrolled as of Q4
2023 reporting, expected readout H2 2025. The investigator-initiated study
is led by Vestre Viken (Drammen Hospital) and supported by Ultimovacs.
About UV1
UV1 is a universal cancer vaccine designed to induce a specific T-cell response
against telomerase. UV1 consists of long, synthetic peptides representing a
sequence in the reverse transcriptase subunit of telomerase (hTERT), shown to
induce CD4+ T-cells. These CD4+ T-cells have the potential to provide
inflammatory signals, and T-cell support is believed to be critical for
triggering a strong anti-tumor immune response. Following intradermal injection,
antigen-presenting cells (APCs) in the skin are exposed to the vaccine peptides.
These APCs will process the peptides and present vaccine epitopes on Human
Leukocyte Antigen (HLA) molecules to naïve T-cells in the lymph nodes. Activated
vaccine-specific T-cells will then enter the circulation and search for cells
displaying their cognate antigen in the context of HLA molecules.
The UV1 peptides contain several epitopes, shown to be non-restrictive in terms
of (HLA) alleles for presentation. It is, therefore not required to perform HLA
pre-screening of patients, which potentially enables broad population
utilization of the vaccine. UV1 is administered over three months as eight
intradermal injections together with the immune-modulator GM-CSF.
