OSE Immunotherapeutics Announces Positive
Efficacy Results for Lusvertikimab in the Phase 2 trial for the
treatment of Ulcerative Colitis
- Lusvertikimab demonstrates
significant efficacy during the 10 week-induction phase of
treatment, in the randomized double-blind CotiKis phase 2
study
- Favorable safety and
tolerability profile in the whole patient population across the two
doses tested and during the open label phase of
treatment
- First anti-IL7R mAb
positive efficacy study enabling pathway of future development to
potential First-in-Class Interleukin-7 antagonist
NANTES, France, July 24th, 2024 – 7:30
am CET- OSE Immunotherapeutics SA (ISIN: FR0012127173; Mnemo:
OSE), today reported first positive results from its
CoTikiS randomized, double-blind, placebo-controlled, Proof of
Concept phase 2 study of Lusvertikimab, a pure antagonist of IL-7
receptor, demonstrating significant efficacy results measured by
the improvement of the Modified Mayo Score** (at week 10 primary
endpoint of the treatment induction phase). A favorable safety
profile was observed during both the induction phase and during the
6 months of open-label extension phase trial.
Nicolas Poirier, Chief Executive Office
of OSE Immunotherapeutics, comments: “We are very excited
to share these first positive Phase 2 efficacy results for
Lusvertikimab in ulcerative colitis, a disabling chronic relapsing
inflammatory bowel disease with a patient population in regular
need of alternative new therapies. This clinical proof of concept
study establishes Lusvertikimab as a potential first-in-class with
novel therapeutic options, based on its differentiated mechanism of
action as a pure interleukin-7 antagonist. We are optimistic about
the potential for patients, these positive clinical efficacy and
safety results represent a strong catalyst for future opportunities
and enhances OSE presence in this growing field of chronic Immune
inflammation.
Frédérique Corallo, CMO
Immuno-Inflammation commented:” We are very grateful to
the patients who participated in this trial, study investigators,
and the global team involved for their strong commitment to achieve
this important clinical milestone”. She added “Lusvertikimab has
shown very interesting efficacy results with the two doses tested
at week-10, in particular on endoscopic improvement, and reinforced
efficacy signal for 34 weeks in the open-label extension. A good
safety profile was observed in the whole patient population. The
full data set will be completed in a specific communication and
presented at future medical congresses.
Lusvertikimab (OSE127) phase 2 Proof of
Concept study vs Placebo in Patients with Moderate to Severe Active
Ulcerative Colitis
(NCT04882007-CoTikiS):
The randomized, double-blind Phase 2 clinical
trial CoTikiS has evaluated the efficacy and the safety of
Lusvertikimab versus placebo in 136 patients with moderate to
severe active UC who failed, lost response, or were intolerant to
previous treatment(s)*. Primary endpoint was the efficacy
assessment of Lusvertikimab versus placebo on the reduction of the
Modified Mayo score** at week 10.
Primary endpoint**: a
significant decrease of the Modified Mayo Score (MMS) is achieved
versus placebo at week 10:
The 850 mg group (n=50, Placebo n=49) in the
principal analysis obtained significant results at week 10 versus
Placebo on the improvement of the MMS with a -0.82 (95%CI: -1.63.
-0.01) differenceµ in treatment effect between lusvertikimab and
placebo (p=0.047).
The 450 mg group (n=35, Placebo n=49) obtained
significant results versus placebo (the 450 mg group was considered
as exploratory as prematurely interrupted***) with a differenceµ of
-1.17 (95%CI: -2.18; -0.16) between lusvertikimab and placebo
(p=0.023).
The global treatment effect is significant
considering the 450+850mg groups together versus placebo showing a
differenceµ of -0.88 (95%CI: -1.64; -0.12) between lusvertikimab
and placebo (p= 0.024).
Safety results: no safety
signal was reported by the Data Safety Monitoring Board during the
trial. Both doses of lusvertikimab show favorable
safety profile in comparison with placebo, with similar rates of
adverse events across the 3 treatment groups.

biological treatments
** Ulcerative Colitis is a chronic inflammatory
disease of the rectum and colon characterised by mucosal
inflammation, abdominal pain associated with symptoms and frequency
of diarrhoea and rectal bleeding. The moderate to severe UC is
measured by a Modified Mayo Score (MMS) between 4
and 9, inclusive. The primary endpoint is the mean change at Week
10 from baseline in the Modified Mayo Score, a Disease Activity
Index for UC defined by the addition of the stool frequency and the
rectal bleeding sub-scores (two patient’s clinical elements as
Patient Reported Outcomes) and the endoscopic sub-score (mucosal
endoscopy activity), assessed by an endoscopist through a central
reading platform.

model)
*** An interim Futility analysis performed early
(33% of patients) by the IDMC proposed interruption of the 450 mg
group for risk of futility but not confirmed at final analysis. The
850 mg group was hence considered as primary analysis.

component of anti-PD1 combined with a new immunotherapy target to
increase anti-tumor efficacy by “cis-potentiating” tumor-specific T
cells. A first program has been acquired by Boehringer
