Trial Outcomes & Findings for Continuation Study of Long-term Safety, Tolerability, Pharmacokinetics and Efficacy of Recifercept in Achondroplasia (NCT NCT05116046)

NCT ID: NCT05116046

Last Updated: 2024-02-08

Results Overview

An AE was any untoward medical occurrence that did not necessarily have a causal relationship with study treatment. TEAE was an AE that occurred after initiation of study treatment that was not present at the time of treatment start or an AE that increased in severity after the initiation of medication, if the event was present at the time of treatment start emerges. SAE was an AE resulting in any of the following outcomes or considered medically significant: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly or birth defect. Severe AEs were AEs that were medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated disabling, limiting self-care activities of daily living.

PRIMARY outcome

Timeframe: From first dose of study drug up to 28 days after last dose of study drug (maximum up to 11 months)

Population: FAS consisted of all participants who received at least one dose of recifercept. Participants were analyzed according to the dose they actually received.

An AE was any untoward medical occurrence that did not necessarily have a causal relationship with study treatment. TEAE was an AE that occurred after initiation of study treatment that was not present at the time of treatment start or an AE that increased in severity after the initiation of medication, if the event was present at the time of treatment start emerges.

The Z-score described how many standard deviations a given measurement lies above or below a size or age-specific population mean. A Z-score above the population mean indicates a positive value, whereas a Z-score below the population mean indicates a negative value. The greater the deviation of the Z-score from zero (in a positive or negative direction), the greater the magnitude of deviation from the mean.

Timeframe: From baseline up to end of study/early termination (for a maximum duration of 11 months)

Population: FAS included all participants who were planned to receive at least one dose of recifercept. Here, 'Overall Number of Participants Analyzed' signifies participants evaluable for this outcome measure.'

Laboratory parameters that were assessed included lymphocytes, neutrophils, eosinophils, monocytes and potassium. Clinically significant abnormal laboratory findings were determined based on investigator's decision.

Population: FAS included all participants who were planned to receive at least one dose of recifercept.

Absolute values and changes from baseline in supine systolic and diastolic blood pressure, oral temperature, and pulse rate were planned to be summarized by treatment in accordance with the sponsor reporting standards. Clinically significant abnormal laboratory findings were those which were not associated with the underlying disease, unless judged by the investigator to be more severe than expected for the participant's condition.
