Layout table for study information
Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 20 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase II Study to Determine the Safety of Defibrotide in Sickle Cell Disease-Related Acute Chest Syndrome
Actual Study Start Date : January 12, 2018
Actual Primary Completion Date : July 1, 2022
Estimated Study Completion Date : July 2023

Arm Intervention/treatment
Experimental: Interventional
Defibrotide 6.25 mg/kg IV q6h
Drug: Defibrotide
Defibrotide 6.25 mg/kg IV q6h up to 7 days
Other Name: Defitelio®

Primary Outcome Measures :
  1. Number of patients with grade III/IV allergic reaction to defibrotide [ Time Frame: 30 days ]
    All patients will be monitored for allergic reaction probably or definitely related to defibrotide administration.

  2. Number of patients with grade III/IV hemorrhage [ Time Frame: 30 days ]
    All patients will be monitored for hemorrhage probably or definitely related to defibrotide.

Secondary Outcome Measures :
  1. Number of patients with improvement in clinical signs of Acute Chest Syndrome [ Time Frame: 30 days ]
    Patients will have pre and post treatment assessments with imaging and blood tests to monitor clinical signs of ACS
