An AE is any untoward medical occurrence in a clinical study participant administered a medicinal product and which does not necessarily have a causal relationship with that product. An SAE is defined as any untoward medical occurrence that, at any dose, meets one or more of the criteria listed: results in death, is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; is a congenital anomaly/birth defect in the offspring of a study participant; or other situations as per the medical or scientific judgment of the Investigator.
An AEMI is an event of scientific and medical concern specific to the Sponsor's product or program, for which ongoing monitoring is appropriate. The following are AEMIs for this study: taste disturbance, oral hypoesthesia, oral paresthesia, and new or worsening findings of the cornea.

Participants rate their pain intensity daily on a numeric rating scale from 0 (no pain) to 10 (worst possible pain). Weekly API scores are derived by averaging daily API scores. Higher score indicates worst outcome. A repeated measures statistical analysis is applied to weekly scores, and the result for the Weeks 7 to 12 interval is obtained by averaging adjusted mean estimates for Weeks 7, 8, 9, 10, 11 and 12.
Assessed by Worst Itch Numeric Rating Scale \[WI-NRS\] The WI-NRS is a single item questionnaire assessing the patient-reported severity of itch at its most intense during the previous 24-hour period on a scale of 0 to 10, with 0 being 'no itch' and 10 being 'the worst itch imaginable'. Higher scores indicate worse severity.

Camlipixant is an investigational oral small molecule developed by GSK plc for chronic pruritus, cough, irritable bowel syndrome, and refractory chronic cough. It is a P2RX3 antagonist and remains in clinical development, with Phase 2 and Phase 3 studies ongoing across these indications. It is not yet approved for any use.
Camlipixant targets P2RX3, a purinergic receptor, and acts as an antagonist. By blocking P2RX3, the drug is designed to reduce signaling associated with cough and related sensory pathways. This target class distinguishes it from other cough therapies that act on different receptors.
Camlipixant is developed by GSK plc, which trades under the ticker GSK. GSK holds the development program for camlipixant across its current indications, including refractory chronic cough and irritable bowel syndrome. The compound is also referenced in the literature by its code name BLU-5937.
Camlipixant is in Phase 2 development overall, though individual studies span Phase 1 through Phase 3. It is investigational and has not been approved by the FDA. Six trials have been conducted or are underway, with five completed and one currently active, enrolling a total of 2,163 participants.
Camlipixant trials include NCT07650084, a Phase 3 China extension study in refractory chronic cough that is recruiting, and NCT07519395, a Phase 2 recruiting study in irritable bowel syndrome with diarrhea and mixed subtypes. Completed studies include NCT06222892 in healthy participants and hepatic impairment, and NCT05959447 on drug-drug interactions.
Yes, camlipixant is also known as BLU-5937. Other names used for the compound include [14C]-BLU-5937 and BLU-5937 ER. These refer to the same P2RX3 antagonist developed by GSK, so searches for BLU-5937 and camlipixant describe the same investigational drug.
