May 22, 2018 updated by: Prolong Pharmaceuticals

A Phase 2 Study of the Safety and Effectiveness of SANGUINATE™ in the Treatment of Vaso-Occlusive Crises in the Ambulatory Setting: A Placebo-Controlled, Single-Dose, Single-Blind Study in Adults With Sickle Cell Disease

Safety and effect of SANGUINATE on Sickle Cell Disease patients experiencing a vaso-occlusive crisis

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Patients who are experiencing a vaso-occlusive crisis will report to the clinic for treatment and screening into the SGSC-005 study. Patients who meet all inclusion/exclusion criteria will be randomized to receive either SANGUINATE 320 mg/kg or placebo (saline) over a 2 hour infusion period. Assessments of vital signs, ECGs, safety labs, adverse events as well as patient and physician questionnaires will be completed up to 6 hours after the start of the infusion. Patients will then be assessed for discharge either to home or admitted to the hospital for further treatment depending on their disease severity. Follow-up phone calls will be completed 24 hours and 7 days after initiation of treatment . A follow-up visit will be completed in the clinic at 72 hours after initiation of treatment.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
24

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Age ≥ 18 years,
  2. Sickle Cell Disease (all genotypes),
  3. Diagnosis of a severe vaso-occlusive crisis (VOC), based on the clinical judgement of the Investigator,
  4. Participant needs to be admitted to the ambulatory site for treatment of VOC requiring IV pain medication,
  5. Able to provide written consent,
  6. Able to receive IV infusion of study drug.

Exclusion Criteria:

  1. In the judgment of the Investigator, the participant is not a good candidate for the study,
  2. An acute severe complication of SCD beyond VOC,
  3. Pregnant or actively trying to become pregnant, or breastfeeding,
  4. Participant had > 6 urgent visits for SCD complications in the prior 3 months,
  5. Fewer than 30 days since any prior treatment with IV pain medication for VOC,
  6. Onset of current acute painful crisis > 3 days prior to dosing,
  7. Evidence of moderate to severe renal insufficiency (CrCl < 50 mL/min) or chronic kidney disease, or of moderate to severe hepatic disease (LFTs > 2 x ULN) based on past medical history,
  8. Concurrent or prior treatment within 90 days with an investigational medication,
  9. Abnormal ECG due to cardiac ischemia and/or atrial fibrillation of acute onset, in the opinion of the Investigator.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Time to readiness for discharge from ambulatory site
Time Frame: 7 Days
Defined as the time from the start of study drug infusion until the time of participant's response that their pain episode has improved enough for discharge; investigator's assessment of participant's readiness for discharge; and participant no longer requires IV opioid administration
7 Days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Safety of treatment
Time Frame: 1 Day
as determined by changes in vital signs, EKG, biochemical, hematological, and urinalysis measures, and reported AEs
1 Day
Extent of reduction in pain score during ambulatory visit as assessed by the participant on a 10-point pain scale
Time Frame: 1 Day
1 Day
Total pain treatment received including the opioid dose (mg/kg) received during ambulatory visit
