Study start date: November 1, 2003Actual date on which the first participant was enrolled.

Open-label therapy will be administered subcutaneously. Patients enrolled will continue to receive Interferon gamma-1b therapy three times per week and will be evaluated at 6-week intervals. Patients not taking Interferon gamma-1b at enrollment will re-initiate therapy with subcutaneous Interferon gamma-1b under a dose-escalation scheme, reaching full dose after 2 weeks.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details
91 patients to be enrolledTotal number of participants that the clinical trial aims to recruit.
Treatment Study
These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

How participants are assigned to different groups/arms
In this clinical study, participants are assigned to groups based on specific criteria, such as their medical history or a doctor's recommendation. This approach ensures that treatments are given to those who may benefit the most, based on known factors.

Other Ways to Assign Participants
Randomized allocation: Participants are assigned randomly, like flipping a coin, to ensure fairness and reduce bias.
None (Single-arm trial): If the study has only one group, all participants receive the same treatment, and no allocation is needed.

How treatments are given to participants
In this study, all participants receive the same treatment. This approach is often used to evaluate the effects of a single intervention without comparing it to another.

Other Ways to Assign Treatments
Parallel assignment: Participants are split into separate groups, each receiving a different treatment.
Cross-over assignment: Participants switch between treatments during the study.
Factorial assignment: Participants receive different combinations of treatments.
Sequential assignment: Participants receive treatments one after another in a specific order, possibly based on individual responses.
Other assignment: Treatment assignment does not follow a standard or predefined design.

How the interventions assigned to participants is kept confidential
Everyone involved in the study knows which treatment is being given. This is typically used when it's not possible or necessary to hide the treatment details from participants or researchers.

Other Ways to Mask Information
Single-blind: Participants do not know which treatment they are receiving, but researchers do.
Double-blind: Neither participants nor researchers know which treatment is given.
Triple-blind: Participants, researchers, and outcome assessors do not know which treatment is given.
Quadruple-blind: Participants, researchers, outcome assessors, and care providers all do not know which treatment is given.
