Recruitment Details

Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Patients were enrolled at 33 centers in 7 countries (Canada, France, Germany, Italy, Switzerland, UK, and USA. The first patient enrolled and started treatment on 8 July 2004 and the last patient enrolled and started treatment on 20 October 2005.

Pre-Assignment Details

Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Patients who completed RAPIDS-2 and who still had digital ulcers (DUs) or developed a new digital ulcer (DU) after the last follow-up visit were eligible. After release of the RAPIDS-2 results, patients who were prematurely discontinued from RAPIDS-2 for treatment failure or, if on placebo, for an adverse event and had DUs were also eligible.

[1]	SHAQ evaluates physical disability. Patients were instructed to rate their capacity to perform activities of daily living within the previous 7 days by checking one of the following descriptors: “without any difficulty”, “with some difficulty,” “with much difficulty,” or “unable to do,” equivalent to scores of 0, 1, 2, and 3, respectively. Items were categorized into 8 domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and activities.
[2]	Overall hand pain related to finger ulcers was assessed by the patient using a Visual Analogue Scale. Patients were instructed to score their pain by marking on the continuous 10-cm scale, where 0 (left) was no pain and 100 (right) very severe pain, in response to the question, “How much pain have you had because of your finger ulcers in the past week?” The investigator measured the distance in millimeters between 0 and the patient mark with the ruler provided and recorded the distance.
[3]	UKFS relates to upper and lower extremity function and muscle weakness. For each item, the patient indicated the responses that best described their current ability: “able to perform in a normal manner,” “able to perform with alteration in style,” “can only manage with difficulty,” and “impossible to achieve.” Each response was given an integer from 0 (able to perform in a normal manner) to 3 (impossible to achieve), and the sum of individual responses provided an overall score of 0 to 33. Missing values were replaced with the worst value the patient reported on the other items at that visit.
