Study Endpoints

Primary Endpoints

Change from baseline in the endoscopic NPS
Baseline to Week 24

The Nasal Polyp Score (NPS) is the sum of the right and left nostril scores, as evaluated by means of nasal endoscopy. Nasal polyp is graded based on polyp size from 0 to 4 with higher scores indicating larger polyps. The sum of right and left nostril scores ranges from 0 (no polyps) to 8 (large polyps).

Incidence of treatment-emergent adverse events (AEs), adverse events of special interest (AESIs), serious adverse events (SAEs), AEs leading to death, and AEs leading to permanent treatment discontinuation
Baseline to EOS (Week 72)

All AEs (serious or nonserious) will be collected from the signing of the ICF until end of study (EOS) visit

Change from baseline in the NCS
Baseline to Week 24

The Nasal Congestion Score (NCS) is scored using a 0-3 categorical scale where 0 = no symptoms, 1 = mild symptoms, 2 = moderate symptoms and 3 = severe symptoms. Outcome value is defined as the preceding 28-day average of morning scores recorded in eDiary.

Incidence of treatment-emergent AEs, AESIs, SAEs, and AEs leading to permanent treatment discontinuation
Baseline up to Week 72

All AEs (serious or nonserious) will be collected from the signing of the informed consent form (ICF) until the end of study visit

Change from baseline in sinus (maxillary, ethmoid) percent opacification volume assessed by CT scan
Baseline to End of Treatment (EOT) (Week 24)

Change from baseline in sinus inflammation as assessed by Computerized Tomography (CT) scan of the sinuses in the itepekimab-- compared to placebo-- treated study participants on the background of intranasal corticosteroid (INCS).

Annualized rate of moderate or severe Pulmonary exacerbations (PEs) over the treatment period
Baseline up to End of Treatment (EOT) (24-52 weeks)

Annualized rate of moderate or severe PEs over the placebo-controlled treatment period

Frequently asked questions about Itepekimab

What is Itepekimab used for?

Itepekimab is an investigational drug being studied for chronic rhinosinusitis with nasal polyps, chronic obstructive pulmonary disease, bronchiectasis, and chronic rhinosinusitis without nasal polyps. It is currently in Phase 2 development for these respiratory conditions.

What does Itepekimab target?

Itepekimab targets IL-33, a cytokine involved in inflammatory responses. It is an inhibitor of IL-33, designed to block its activity. This mechanism is being investigated for its potential to treat chronic rhinosinusitis with nasal polyps and other respiratory conditions.

Who makes Itepekimab?

Itepekimab is being developed by Sanofi, a global biopharmaceutical company. Sanofi is listed on the stock exchange under the ticker symbol SNY.

What phase is Itepekimab in?

Itepekimab is in Phase 2 clinical development. It is an investigational drug and has not been approved by regulatory authorities. It is being studied for chronic rhinosinusitis with nasal polyps and other respiratory conditions.

What clinical trials is Itepekimab in?

Itepekimab is being studied in several clinical trials, including NCT06834347, NCT06834360, NCT07424144, and NCT07484230. These trials are investigating its efficacy and safety in chronic rhinosinusitis with nasal polyps, with some trials enrolling participants in multiple countries.

Is Itepekimab the same as SAR440340?

Yes, Itepekimab is also known as SAR440340. Both names refer to the same investigational drug being developed by Sanofi for respiratory conditions.
