|Pneumonia Idiopathic Pneumonia Syndrome||Drug: Etanercept Drug: Placebo plus corticosteroid||Phase 3|
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
|Official Title:||A Randomized Double-Blind, Placebo-Controlled Trial of Soluble Tumor Necrosis Factor Receptor: Enbrel (Etanercept) for the Treatment of Acute Non-Infectious Pulmonary Dysfunction (Idiopathic Pneumonia Syndrome) Following Allogeneic Cell Transplantation (BMT CTN #0403)|
- Response Rate [ Time Frame: Day 28 ]Response will be defined as survival to Day 28 of study, plus discontinuation of all supplemental oxygen support for more than 72 consecutive hours by Day 28.
- Response to Therapy [ Time Frame: Day 56 ]Response will be defined as the ability to survive to Day 56 of study, plus the ability to completely discontinue all supplemental oxygen support for > 72 consecutive hours during this time period.
- Discontinuation of Supplemental Oxygen [ Time Frame: Day 56 ]The "time required to discontinue supplemental oxygen" will be measured in the number of days from study entry.
- Corticosteroid Dose [ Time Frame: Day 14 and 28 ]Patients were treated with systemic corticosteroids with methylprednisolone at 2 mg/kg/day on day 0, with taper allowed after day 7.
- Overall Survival [ Time Frame: Year 1 ]Percentage of patients that survived after one year
- Incidence of Infection [ Time Frame: Day 56 ]
- Incidence of Toxicity [ Time Frame: Day 56 ]
- Incidence of Graft-vs-Host-Disease (GVHD) [ Time Frame: Year 1 ]
- Incidence of Relapse [ Time Frame: Year 1 ]Percentage of patients who experience relapse. Deaths without relapse are considered as a competing risk.
- Overall Mortality [ Time Frame: Year 2 ]
- Dermatologic Reaction [ Time Frame: Day 28 ]
- Pro-inflammatory Markers of Pulmonary Disease, in Both BAL Fluid and Plasma [ Time Frame: Day 28 ]

Etanercept plus corticosteroids
Etanercept will be given eight doses of study drug over a 4-week period. The initial dose of etanercept will be administered intravenously on Day 0, with subsequent doses administered subcutaneously (SQ). Dosing will be administered twice weekly over 4 consecutive weeks. Additionally, patients in both arms will receive corticosteroids (2 mg/kg/day) Day 0 through Day 7, with subsequent taper as clinically indicated.
Other Name: Enbrel®
Active Comparator: Placebo
Placebo plus Corticosteroids
Drug: Placebo plus corticosteroid
Patients will receive a total of eight doses of placebo over a 4-week period. The initial dose of placebo will be administered intravenously on Day 0, with subsequent doses administered subcutaneously (SQ). Dosing will be administered twice weekly over 4 consecutive weeks. The placebo will be the inert diluent used for the etanercept formulation.
Additionally, patients in both arms will receive corticosteroids (2 mg/kg/day) Day 0 through Day 7, with subsequent taper as clinically indicated.
Other Name: Methylprednisolone
Over the last two decades, allogeneic hematopoietic cell transplantation (HCT) has emerged as an important treatment for a number of malignant and non-malignant disorders. Unfortunately, several complications, including graft-versus-host disease (GVHD) and pulmonary dysfunction, limit the utility of this aggressive form of therapy. Infectious and non-infectious lung complications occur in 25% to 55% of HCT recipients and account for up to 50% of transplant-related mortality. In about half of affected patients, no infectious organisms are identified in the lungs. Two major types of non-infectious pulmonary injury are recognized: acute idiopathic pneumonia syndrome (IPS) and sub-acute lung injury (obstructive airway disease or bronchiolitis obliterans [BrOb] and restrictive lung disease). The current study will examine the use of etanercept in patients with IPS.
Eligible patients will be randomized to receive one of two arms of therapy: (A) etanercept plus corticosteroids, or (B) placebo plus corticosteroids. Patients will receive a total of eight doses of etanercept (or placebo) over a 4-week period. The initial dose of etanercept (or placebo) will be administered intravenously on Day 0, with subsequent doses administered subcutaneously (SQ). Dosing will be administered twice weekly over 4 consecutive weeks. The placebo will be the inert diluent used for the etanercept formulation.
Additionally, patients in both arms will receive corticosteroids (2 mg/kg/day) Day 0 through Day 7, with subsequent taper as clinically indicated. Chest radiographs shall be obtained weekly through Day 28. Plasma cytokine profiles will be obtained on Days 0, 7, and 28.
For patients < 30 days post-transplant: If the patient's clinical condition is such that a broncho-alveolar lavage (BAL) is deemed "not possible to be performed" by the treating physician (or pulmonologist), then the "on study" BAL may be waived. In such circumstances, the patient may register and be randomized to study therapy without the BAL being undertaken.
For patients not on mechanical ventilation: If a BAL is not done, appropriate virology studies on a nasal swab (or nasal washing) are required as a minimum procedure to study entry.
For patients on mechanical ventilation: Microbiologic studies of a deep endotracheal aspirate are allowed in lieu of a formal bronchoscopy procedure. However, no protocol-specified biologic studies (see Section 4.4) will be done on these specimens.
For patients 31-180 days post-transplant: An "on study" bronchoscopy is required in all cases.
If, at any point following initiation of study drug therapy, previously obtained BAL fluid cultures or other BAL fluid analysis become positive for an infectious pathogen, study drug therapy shall be discontinued at that point, and not re-instituted. The patient will discontinue study drug therapy, but will still be followed for outcome.
The primary study endpoint is response at Day 28. Patients who discontinue study drug therapy for any reason will still be followed for primary and secondary study endpoints.
