Abatacept for the Treatment of Common Variable Immunodeficiency With Interstitial Lung Disease
(ABCVILD)
What this study is about
There is no the usual treatment therapy for patients with granulomatous-lymphocytic interstitial lung disease (GLILD) seen in common variable immunodeficiency (CVID). Abatacept has recently looked promising for the treatment of patients with complex CVID.
View original scientific description
There is no standard of care therapy for patients with granulomatous-lymphocytic interstitial lung disease (GLILD) seen in common variable immunodeficiency (CVID). Abatacept has recently looked promising for the treatment of patients with complex CVID. This study is a multi-site, phase II, randomized, blinded/placebo-controlled clinical trial in pediatric and adult subjects to determine the efficacy of abatacept compared to placebo for treatment of subjects with GLILD in the context of CVID.
Interventions
DRUG
Abatacept
Abatacept is a selective costimulation modulator, inhibiting T lymphocyte activation by binding to CD80 and CD86, thereby blocking interaction with CD28. Orencia solution supplied in a prefilled syringe should be refrigerated at 2C to 8C (36F to 46F). Orencia should not be used beyond the expiration date on the prefilled syringe. The product should be protected from light by storing in the original package until time of use. The prefilled syringe should not be frozen.
OTHER
Placebo
The composition of the placebo for Orencia is the same as the active study drug without the abatacept. The placebo will be packaged and labeled as described above for the Orencia prefilled syringes. To maintain the blind, injection volumes will be the same as the active treatment.
Primary outcome measures
High Resolution CT Scan of the chest (HRCT)
Time frame: 6 months
Proportion of subjects achieving a significant response (defined as \>30 percent change in lung tissue disease burden by GLILD) on HRCT after 6 months of abatacept therapy.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
