Aeterna Zentaris Announced Presentation of Positive Results from First Pediatric Study of Macimorelin at the 22nd European Congress of Endocrinology
Aeterna Zentaris Inc. announced positive findings from its pediatric study of macimorelin for evaluating childhood-onset growth hormone deficiency (CGHD). The pharmacokinetics (PK) and pharmacodynamics (PD) profiles were comparable to adult data, supporting a 1.0 mg/kg dose for future studies. The Phase 3 trial, Study P02, is set to begin in Q1 2021. The study showed excellent safety and tolerability with no serious adverse events linked to macimorelin. This research aims to address significant unmet needs in CGHD treatment, enhancing the company's market position.

CHARLESTON, S.C., Sept. 08, 2020 (GLOBE NEWSWIRE) -- Aeterna Zentaris Inc. (NASDAQ: AEZS) (TSX: AEZS) (the “Company”), a specialty biopharmaceutical company commercializing and developing therapeutics and diagnostic tests, today announced the presentation of results from its first pediatric study of macimorelin as a growth hormone stimulation test for the evaluation of childhood-onset growth hormone deficiency (“CGHD”) at the 22nd European Congress of Endocrinology (e-ECE 2020), being held September 5-9, 2020.
The data were presented during the event in an ePoster titled, Pharmacokinetics and pharmacodynamics of macimorelin acetate (AEZS-130) in paediatric patients with suspected growth hormone deficiency (GHD), accommodated by an audio commentary. The full poster is now available on the Company’s website.
“We are grateful to have the opportunity to present at the e-ECE 2020 congress. We are incredibly encouraged by the results from this study, which demonstrated macimorelin’s safety and tolerability, and a PK and PD profile in a range expected from the adult development program,” commented Dr. Nicola Ammer, Chief Medical Officer of Aeterna Zentaris. “As we advance into our pivotal Study P02, which we expect to initiate in the first quarter of 2021, we are confident that we have selected with 1.0 mg/kg macimorelin the correct dosing regimen based on insights gained from the Study P01.”
The AEZS-130-P01 study (“Study P01”), was an open-label, group comparison, dose escalation trial and the first of two studies as agreed with the European Medicines Agency (“EMA”) in the Company’s Pediatric Investigation Plan (“PIP”) for macimorelin. Study P01 was designed to investigate the pharmacokinetics (“PK”), pharmacodynamics (“PD”), safety, and tolerability of macimorelin after single oral dosing of 0.25, 0.5, and 1.0 mg/kg in pediatric patients with suspected growth hormone deficiency (“GHD”).
The Company completed the study and announced positive results in April 2020. The completed study included 24 subjects aged 4 to 15 years. In the subjects who completed the study in accordance with the protocol, macimorelin demonstrated an excellent safety and tolerability profile. There were 88 adverse events (“AE”) reported in 23 subjects, none of which was assessed by the investigator as related to macimorelin. The majority of AEs (approximately

About Macimorelin
Macimorelin, a ghrelin agonist, is an orally-active small molecule that stimulates the secretion of growth hormone from the pituitary gland. Stimulated growth hormone levels are measured in blood samples after oral administration of macimorelin for the assessment of GHD.
In December 2017, the United States Food and Drug Administration (“FDA”) granted Aeterna Zentaris marketing approval for Macrilen™ to be used in the diagnosis of patients with adult growth hormone deficiency (AGHD). Macimorelin acetate has been granted Orphan Drug designation by the FDA for diagnosis of GHD. In January 2019, the European Commission granted marketing authorization for macimorelin to Aeterna Zentaris for diagnosis of growth hormone deficiency in adults. In March 2017, the Pediatric Committee of the EMA agreed to the Company’s PIP for macimorelin, a prerequisite for filing a marketing authorization application for any new medicinal product in Europe.
