Efficacy and Safety Study of Ryanodex as Adjuvant Treatment in Subjects With Psychostimulant Drug-Induced Toxicity (PDIT)

March 29, 2021 updated by: Eagle Pharmaceuticals, Inc.

Phase 2, Multiple-Site, Open-Label, Randomized, 2-Group, Parallel Study to Assess the Efficacy and Safety of Ryanodex(R) (EGL-4101)as Adjuvant Treatment in Subjects With Psychostimulant Drug-Induced Toxicity (PDIT)

Ryanodex is being investigated as a potential adjuvant treatment for people suffering from psychostimulant drug-induced toxicity (PDIT), a life-threatening medical condition that results mainly from the abuse of certain illicit drugs, most notably methamphetamine, and related forms (MDMC or "Molly"; MDMA or "Ecstasy"). Ryanodex is approved for the treatment of malignant hyperthermia in conjunction with appropriate supportive measures and for prevention of malignant hyperthermia in patients at high risk and in this study, will be investigated for the treatment of PDIT. The hypothesis of this study is that administration of Ryanodex as adjuvant treatment to Standard of Care (SOC) will improve the clinical outcome compared with SOC alone, in subjects with psychostimulant drug induced toxicity. Current SOC is defined as body cooling and supportive measures.

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

This study will be conducted at pre-hospital emergency care (PHEC) facilities. The PHECs are medical units that are fully equipped and staffed to provide adequate emergency medical care to patients with PDIT. The study is designed to evaluate the safety and efficacy of Ryanodex in an on0site pre-hospital emergency setting where subjects are anticipated to be treated over a short period of time and then transferred to another medical facility or released. After screening and diagnosis of PDIT, SOC treatment will be initiated. Subjects eligible for the study will be randomized to either receive SOC + Ryanodex or to receive SOC only. Study subjects are expected to remain at the study site for a maximum of 6 hours post-baseline.

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: Male and non-pregnant subjects diagnosed with psychostimulant drug induced toxicity as evidenced by all of the following: core body temperature of greater than or equal to 39.5 degrees C; organ dysfunction, as evidenced by a Logistic Organ Dysfunction System score of greater than or equal to 6 (In the event of any delay in obtaining the results for baseline LODS score determination, subject may be enrolled. After enrollment, if the pending baseline LODS score turns out to be less than 6, the subject will be withdrawn from the study and replaced); known or suspected us of a psychostimulant drug in the judgment of the Investigator; negative blood pregnancy test for females (in the event of any delay in obtaining pregnancy test result, subject may be enrolled and randomized if all of the other eligibility criteria are met).

Exclusion Criteria: Diagnosed with or is suspected to have an acute, clinically severe infection, which may, in the opinion of the Investigator, may increase the subject's risk for participating in the study an/or may impair the ability of performing and/or interpreting study assessments; severe hyperthermia secondary to a condition other than a psychostimulant drug-induced toxicity; likelihood of head trauma in the past 3 months, or other systemic disease that might increase the subject's risk for participating in the study and/or may impair the ability of performing and/or interpreting study assessments; positive pregnancy test or evidence of active lactation; known history of allergy or hypersensitivity to dantrolene; known history of seizure disorders or epilepsy; current or prior use (within the past 2 weeks) of calcium channel blockers.

Ryanodex (dantrolene sodium) for injectable suspension, 250 mg/vial to be reconstituted in 5 mL of sterile water for injection to yield a 50 mg/mL suspension that will be administered as a rapid IV push of 2.5 mg/mL.
NO_INTERVENTION: Standard of Care only (SOC)
Standard of Care is defined as efficient body cooling by physical methods and supportive methods and supportive measures[ice packs, evaporative cooling (application of room temperature water via mist with use of a fan], benzodiazepines to ameliorate shivering, IV fluids, respiratory support, and other treatments deemed necessary to treat complications or comorbidities].

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
Proportion of Subjects Who Achieved a Logistic Organ Dysfuction System (LODS) Total Score Less Than or Equal to 5
Time Frame: At or prior to 60 minutes post-randomization
Logistic Organ Dysfunction System (LODS) score (measure/scoring of 1-3 specific parameters in 6 organ systems; neurologic, cardiologic, renal, pulmonary, hematologic, and hepatic). One to 5 LODS points are assigned to the levels of severity and the resulting LODS scores range can range from 0 to 22 points. A lower score represents a better outcome; a score of 0 points is a better outcome than a score o 22 points.
At or prior to 60 minutes post-randomization

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
Proportion of Subjects Who Achieved a LODS Total Score Less Than or Equal to 5 at Other Planned Time Points.
Time Frame: Up to 6 hours post-dose.
Proportion of subjects who achieved a LODS total score less than or equal to 5 at other planned time points. One to 5 LODS points are assigned to the levels of severity and the resulting LODS scores range can range from 0 to 22 points. A lower score represents a better outcome.
Up to 6 hours post-dose.
