About this trial
The purpose of this study is to estimate and compare the incidence of overall malignancy, serious infection, and opportunistic infections between new users of ustekinumab and new users of other biologic therapies among adult participants with Crohn's disease (CD) or ulcerative colitis (UC).
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Adult men and women with CD or UC who are new users of ustekinumab or the comparator drugs during the study period
Participants must have at least 1 year of enrollment history with the DoD EHR database immediately prior to new use (that is, exposure index date) of ustekinumab or the comparator drugs
Disqualifiers
Participants below 18 years of age on the exposure index date
Participants who do not meet the definition for CD or UC prior to or on the exposure index date
Participants with any records of human immunodeficiency virus (HIV) diagnosis, organ or tissue transplant, or malignancy (excluding non-melanoma skin cancer [NMSC]) at any time prior to or on the exposure index date
Participants with a physician diagnosis of rheumatoid arthritis, ankylosing spondylitis, or psoriatic arthritis within 12 months prior to or on the exposure index date
Trial population
The study population will include participants with Crohn's Disease (CD) or Ulcerative Colitis (UC) who are new users of ustekinumab and new users of the comparator drugs which will be identified from the Department of Defense (DoD) Electronic Health Records (EHR) database.

Treatments tested in this trial
Ustekinumab
DrugParticipants who are new users of ustekunumab will be included in the cohort. No study treatment will be administered as a part of this study.
Other Biologic Therapies
DrugParticipants who are new users of other biologic therapies (for examples for example, infliximab, adalimumab, or vedolizumab administered as per the prescription record) will be included in this cohort. No study treatment will be administered as a part of this study.
Treatment groups
Trial outcomes
Primary outcomes
Incidence Rate for Malignancy
The incidence rates for malignancy (including Non-melanoma skin cancer \[NMSC\]) will be estimated as the number of incident cases (that is, counts of unique participants) divided by the total at-risk time.
Secondary outcomes
Opportunistic Infection (OI)
The OI will be estimated as the number of incident cases (that is counts of unique participants) divided by the total at-risk time.
Serious Infection
The serious infections will be estimated as the number of incident cases (that is counts of unique participants) divided by the total at-risk time.
