Phase 4 clinical trials in plain English

The product is already approved for some use. The study asks new real-world or additional-use questions.

Phase 4 (post-marketing) studies happen after a product is approved for at least one use. They may look at longer follow-up, other populations, or additional outcomes.

Approved for one disease is not the same as approved for the use in a given NCT record. Read the condition and eligibility on the official page.

Phase 4: testing Biological Drug for Crohn Disease

With this prospective, randomly assigned, multicentre, parallel group pragmatic non-inferiority trial, the investigators will evaluate if endoscopy-driven introduction of biological therapy is not leading to more postoperative endoscopic recurrence at week 86 compared to systematic prophylactic biological therapy in patients with CD undergoing an ileocolonic resection with ileocolonic anastomosis. Secondary analyses will include influence on clinical, biological and surgical CD recurrence, serious side effects, direct costs, work productivity, and quality of life.

Phase 4: testing Ustekinumab for Psoriasis

The investigators propose to improve the possibility of reaching skin resolution by identifying certain markers or gene patterns that may predict patient response to certain psoriasis drugs ahead of time, thus eliminating or reducing the trial-and-error approach often employed. The ability to rule out (or in) specific therapeutics based on predictive how well it works would lead to a more personalized approach for psoriasis treatment.

Phase 4: testing Herpes Zoster Subunit (HZ/su) Vaccine for Systemic Lupus Erythematosus

This randomly assigned, neither you nor the study doctors know who gets the real treatment, compared with a dummy treatment, non-inferiority crossover study will measure the Herpes Zoster Sunbit (HZ/su) vaccine in SLE patients in order to evaluate safety and immunogenicity in patients with variable baseline clinical activities, ages and immunosuppressant exposures. The investigators hypothesize that HZ/su administration will be non-inferior to dummy treatment (placebo) with respect to the risk of moderate or severe SLE flare(s) occurring within 24 weeks of receiving the first dose of the assigned treatment.

Phase 4: testing GLP-1 receptor agonist for Morbid Obesity

Glucagon-like peptide 1 (GLP-1) is a hormone that helps regulate blood glucose levels through improved insulin sensitivity and release of insulin from the pancreas, control hunger, induce satiety and plays a role in the metabolic health of a person. GLP-1 receptor agonists (GLP1-RAs) have been shown to be effective in achieving weight loss in patients with type 2 diabetes while improving blood glucose control.

Phase 4: testing Adalimumab for Crohn's Disease

A substantial fraction of IBD patients with an initial response to infliximab or adalimumab later experience re-emerging active disease despite ongoing anti-Tumour Necrosis Factor (TNF) agents maintenance therapy. The optimal intervention in patients with secondary loss-of-response (LOR) is still poorly defined, as there are still scant data on how best to choose the next intervention from among dose-intensification, switch to another anti-TNF or switch out of the anti-TNF class.
