| KF group | EXPERIMENTAL | In each study visit, patients will receive enough pills for the next month. At the first visit, patients receiving ketotifen (KF) will receive four vials sequentially numbered (1 to 4) containing enough pills for one week each, and will be instructed by the clinician and by the pharmacist to use vial 1 for the first week (0.5 mg of KF BDI), vial 2 for the second week (1mg of KF BDI), vial 3 for the third week (2 mg of KF BDI), and vial 4 for the fourth week (3mg of KF BDI). As for weeks 4, 8 and 12 visits, patients treated with KF will receive four equal vials containing enough pills for one week each (3 mg of KF BDI) |
| Placebo group | PLACEBO_COMPARATOR | Patients participating in the placebo group will also receive sequentially numbered vials at the first visit. Similarly, patients taking placebo will also receive four equal vials of pills on the next visits. |
| SOC | ACTIVE_COMPARATOR | Standard of care - patients who refuse to participate in the study but allow us to compare their clinical data to that of participants of the study |

Ketotifen is being investigated for the treatment of widespread chronic pain. It is a small molecule therapeutic in Phase 3 clinical development. The drug is being studied in a placebo-controlled trial to evaluate its effects on chronic widespread pain, a condition characterized by pain throughout the body.
Ketotifen is an antihistamine and mast cell stabilizer that works by blocking histamine receptors and preventing the release of inflammatory mediators from mast cells. This mechanism is thought to reduce pain signaling and inflammation associated with widespread chronic pain conditions.
Ketotifen is being developed by Edwards Lifesciences Corporation, a company traded on the New York Stock Exchange under the ticker symbol EW. The company is conducting clinical research to evaluate the drug's efficacy in treating widespread chronic pain.
Ketotifen is currently in Phase 3 clinical development for widespread chronic pain. The drug has completed a Phase 3 trial, and it remains investigational, meaning it has not yet been approved by regulatory authorities for commercial use.
Ketotifen has been studied in a Phase 3 clinical trial with the identifier NCT02984397, titled 'Chronic Widespread Pain and White Blood Cell Activation.' This completed trial enrolled 44 participants in Canada, including individuals aged 14 years and older, and used a randomized, double-blind, placebo-controlled design.
Ketotifen is a well-known antihistamine drug that has been available for many years for the treatment of allergic conditions such as conjunctivitis and asthma. In the context of this clinical development program, it is being repurposed for the treatment of widespread chronic pain.
