Effectiveness and safety of rhIGF1 therapy in patients with or without Laron syndrome.

ABSTRACT:

Objective

The European Increlex® Growth Forum Database Registry monitors the effectiveness and safety of recombinant human insulin-like growth factor-1 (rhIGF1; mecasermin, Increlex®) therapy in patients with severe primary IGF1 deficiency (SPIGFD). We present data from patients with and without a reported genetic diagnosis of Laron syndrome (LS).

Design

Ongoing, open-label, observational registry (NCT00903110).

Methods

Children and adolescents receiving rhIGF1 therapy from 10 European countries were enrolled in 2008-2017 (n = 242). The treatment-naïve/prepubertal (NPP) cohort (n = 138) was divided into subgroups based on reported genetic diagnosis of LS (n = 21) or non-LS (n = 117). Multivariate analysis of the NPP-non-LS subgroup was conducted to identify factors predictive of growth response (first-year-height standard deviation score (SDS) gain ≥ 0.3). Assessments included change in height and weight over 5 years and adverse events (AEs).

Results

Height SDS gain from baseline was greater in the NPP-LS than the NPP-non-LS subgroup after 1 years' treatment (P < 0.05). In the NPP-non-LS subgroup, 56% were responders; young age at baseline was a positive independent predictive factor (P < 0.001). NPP-non-LS-responders and the NPP-LS subgroup had a similar mean age (6.07 years vs 7.00 years) at baseline and height SDS gain in year 1 (0.64 vs 0.70), although NPP-non-LS-responders were taller (P < 0.001) at baseline. BMI SDS changes did not differ across subgroups. Treatment-emergent AEs were experienced by 65.3% of patients; hypoglycaemia was most common.

Conclusions

In most NPP children with SPIGFD, with or without LS, rhIGF1 therapy promotes linear growth. The safety profile was consistent with previous studies.

Project description:ImportanceOral propranolol is widely considered to be first-line therapy for complicated infantile hemangioma, but its use in patients with PHACE (posterior fossa malformations, hemangioma, arterial anomalies, cardiac defects, eye anomalies) syndrome has been debated owing to concerns that the cardiovascular effects of the drug may increase the risk for arterial ischemic stroke.ObjectiveTo assess the incidence of adverse events among patients with PHACE syndrome receiving oral propranolol for infantile hemangioma.Design, setting, and participantsThis multicenter retrospective cohort study assessed the incidence of adverse events among 76 patients with PHACE syndrome receiving oral propranolol for infantile hemangioma at 11 tertiary care, academic pediatric dermatology practices. Medical records from January 1, 2010, through April 25, 2017, were reviewed.ExposuresPatients received oral propranolol, 0.3 mg/kg/dose or more.Main outcomes and measuresThe main outcome was the rate and severity of adverse events occurring throughout the course of treatment with oral propranolol, as documented in the medical records. Adverse events were graded from 1 to 5 using a scale derived from the Common Terminology Criteria for Adverse Events and were considered to be serious if they were grade 3 or higher.ResultsA total of 76 patients (59 girls and 17 boys; median age at propranolol initiation, 56 days [range, 0-396 days]) met the inclusion criteria. There were no reports of serious adverse events (ie, stroke, transient ischemic attack, or cardiovascular events) during treatment with oral propranolol. A total of 46 nonserious adverse events were reported among 29 patients (38.2%); the most commonly reported nonserious adverse events were sleep disturbances and minor gastrointestinal tract and respiratory tract symptoms. In a comparison with 726 infants who received oral propranolol for hemangioma but did not meet criteria for PHACE syndrome, there was no significant difference in the rate of serious adverse events experienced during treatment (0 of 76 patients with PHACE syndrome and 3 of 726 patients without PHACE syndrome [0.4%]).Conclusions and relevanceThis study found that oral propranolol was used to treat infantile hemangioma in 76 patients with PHACE syndrome and that no serious adverse events were experienced. These data provide support for the safety of oral propranolol in this patient population.
