The main purpose of this study is to evaluate how well the autoinjector works in a group of people who are likely to use the autoinjector for injecting their medicine in the future. However, no active medicine is given by the autoinjector.

Condition Intervention
Rheumatoid Arthritis
Psoriatic Arthritis
Ankylosing Spondylitis
and Psoriasis
Device: Centocor autoinjector is a prefilled, spring-powered, disposable device for the subcutaneous administration of liquid biologic drug products.

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Official Title: An Open-Label, Randomized, Validation Study to Establish That the Design, Functionality, and Ergonomic Features of the Autoinjector Conform to Defined User Needs and Intended Use for Self-Administration by Subjects With Rheumatoid Arthritis, Psoriatic Arthritis, Ankylosing Spondylitis, or Psoriasis

Primary Outcome Measures:
  • To establish that the autoinjector, as designed, meets defined user needs and intended use for self administration by patients with RA, PsA, AS, and psoriasis.

Secondary Outcome Measures:
  • To establish that the specific training, including the instructional video and the Instructions for Use, are appropriate, easy to understand, and able to be followed and implemented by patients with RA, PsA, AS, and psoriasis.

Detailed Description:

The main purpose of this study is to evaluate how well the autoinjector works in a group of people who are likely to use the autoinjector for injecting their medicine in the future. However, no active medicine is given in the autoinjector. This device (called an autoinjector) automatically injects medicine under the skin with a sterile needle, and is similar to other types of autoinjectors currently being used for this purpose. This trial has been designed to make sure that people, who are likely to use this device, are able to self-inject and understand the training material. A total of 68 subjects took part in the study. About half (30 patients) will have either Rheumatoid Arthritis (RA), psoriatic arthritis (PsA) or ankylosing spondylitis (AS) and the other half will have psoriasis (a type of skin disease), since this device will be used by patients with one of these diseases to inject their medication. The study is designed to have each patient complete 2 self-injections with the autoinjector in 2 different sites-one in the front of the thigh and one in the abdomen 2 inches away from the navel. The order of the first injection location is decided by randomization. The patient will have an equal chance of having the thigh or the abdomen as the first injection. The study staff will assess the subject's safety prior to the patient leaving the clinic. Two prefilled, 1mL placebo autoinjectors for subcutaneous injection
