Brief Summary
The purpose of this study is to learn about the safety of the safety of the study medicine called infliximab for the possible treatment of rheumatoid arthritis (RA), ulcerative colitis (UC, Crohn's disease, or psoriasis. RA is a kind of joint disease that causes pain and swelling. UC causes inflammation and sores (also called ulcers), in the lining of the rectum and colon. Chron's disease is a disease that lasts for a long time and causes severe irritation in your digestive tract. Psoriasis is a skin disease that gives you a dry, scaly rash. The study includes patient's data from the database who:
- Have at least 90 days of look-back period
- Have any of these diseases (RA, UC, Crohn's disease, or Psoriasis) in the 90-day look back period
- Are 15 years of age or older at the time of first dosing All the patient's data included in this study would have received infliximab as intravenous (into veins) injection.

Outcome Measures
Primary Outcomes (1)
Incidence Rate of Serious Infections
The observation of serious infections was expected to occur in an acute time period following any exposure. An incident event occurring during the 60-day risk window was counted in the numerator for the analysis and the person-time accrued until the first occurrence of an event, the end of the 60-day risk window, date of switch treatment, death, or the end of study period. Additionally, two types of analyses based on propensity score were conducted. For the full analysis set, 9 and 232 events occurred with a total of 151.9 and 2609.9 person-years in the Infliximab-Pfizer Biosimilar group and Remicade group, respectively. For the comparative analysis set, 5 and 232 events occurred with a total of 22.8 and 2609.9 person-years. For the comparative analysis set (IPTW weighted), 0.5 and 230.7 events occurred with a total of 3.6 and 2598.5 person-years. For the comparative matched analysis set, 5 and 6 events occurred with a total of 22.8 and 46.7 person-years.
From index date up to 60 days after last dose

Remicade
Eligibility Criteria
The study population includes individuals who have a diagnosis of rheumatoid arthritis, ulcerative colitis, Crohn's disease, or psoriasis and have been exposed to Infliximab-Pfizer Biosimilar or the innovator (Remicade) with a planned study period between December 1, 2018 and November 30, 2023.
You may qualify if:
- Have at least 90 days of look-back period
- Have diagnostic code of indicated diseases (rheumatoid arthritis, ulcerative colitis, Crohn's disease, or psoriasis) in the 90-day look-back period. Patients with \>1 indication will be summarized as a separate group from each sub-cohort. An inpatient or outpatient visit assigned a diagnosis code consistent with either rheumatoid arthritis, ulcerative colitis, Crohn's disease, or psoriasis using ICD-10 coding.
- years of age or older at the time of index date
You may not qualify if:
- \. Patients with pre-existing safety outcome event during the 90-day look-back period will be excluded from the study cohort for that specific outcome event as this study is observing incident cases.
