Trial Outcomes & Findings for Efficacy and Safety Study of Ryanodex as Adjuvant Treatment in Subjects With Psychostimulant Drug-Induced Toxicity (PDIT) (NCT NCT03189433)

Last Updated: 2021-03-30

Results Overview

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.

Measure	Ryanodex + Standard of Care Ryanodex (dantrolene sodium) 50 mg/mL suspension to be administered as a rapid IV push of 2.5 mg/kg, added to Standard of Care (SOC). SOC is defined as efficient body cooling by physical 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\]. Administer a single dose of Ryanodex. If a subject does not show an adequate clinical response within 10 - 30 minutes post-dose, a second IV bolus dose of 2.5 mg/kg may be administered. Ryanodex (dantrolene sodium) for injectable suspension: 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.	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\].

PRIMARY outcome

Timeframe: At or prior to 60 minutes post-randomization

Population: Due to lack of enrollment, data was insufficient for a meaningful analysis. Data were not collected.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: Up to 6 hours post-dose.

Population: Data were not collected and thus could not be analyzed.

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.
