An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The number of participants who experienced an AE is presented.

Number of Participants Who Discontinue Study Intervention Due to an AE
Up to approximately 85 days

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The number of participants who discontinued study intervention due to an AE is presented.

Frequently asked questions about MK-6194

What is MK-6194 used for?

MK-6194 is an investigational monoclonal antibody being studied for ulcerative colitis, atopic dermatitis, and in healthy volunteers. It is in Phase 1 clinical development and is not approved by the FDA. Studies have been completed in participants with active ulcerative colitis and atopic dermatitis, as well as in healthy adults.

Who makes MK-6194?

MK-6194 is being developed by Merck & Company, Inc., which trades under the ticker MRK. The company is conducting Phase 1 clinical trials of this investigational monoclonal antibody across multiple countries, including the United States, for conditions such as ulcerative colitis and atopic dermatitis.

What phase is MK-6194 in?

MK-6194 is in Phase 1 clinical development. Multiple Phase 1 trials have been completed, including studies in ulcerative colitis, atopic dermatitis, and healthy volunteers. As an investigational drug, it has not been approved by regulatory authorities and remains in early-stage clinical testing.

What clinical trials is MK-6194 in?

MK-6194 has completed several Phase 1 trials. NCT04924114 studied it in active ulcerative colitis with 57 participants. NCT05450198 examined multiple rising doses in atopic dermatitis with 72 participants. NCT06649877 and NCT06821334 evaluated it in healthy adults, including a Chinese participant study.

Is MK-6194 the same as PT101?

Yes, MK-6194 is also known as PT101. One clinical trial, NCT04924114, is titled "A Study of MK-6194 (PT101) in Participants With Active Ulcerative Colitis." This alternative name may appear in research publications and trial registries.
