New drugs for children in 2019-2020


The impact of the Best Pharmaceuticals for Children Act and the Pediatric Research Equity Act continues to benefit children’s health.

The past year has seen several new drugs for orphan diseases including 2 for Duchenne muscular dystrophy (DMD), a new combination drug for cystic fibrosis (CF), an anticonvulsant for Dravet syndrome (DS), and 2 potentially disease modifying drugs for sickle cell anemia (SCA).

New drugs


In November 2019 the US Food and Drug Administration (FDA) approved 2 therapies for SCA. Adakveo is a monoclonal antibody which binds to P-selectin, blocking interactions with its ligands including P-selectin glycoprotein ligand 1.1 The binding of P-selectin on the surface of activated endothelium and platelets prevents interactions between endothelial cells, platelets, leukocytes, and erythrocytes. Results from SUSTAIN 2 demonstrated a decreased rate of vaso-occlusive pain crises. Adakveo is approved for patients aged 16 years and older, given as a 30-minute IV infusion at weeks 0, 2, and 4, and then every 4 weeks.

Oxbryta inhibits polymerization of hemoglobin S, thus increasing its affinity for oxygen.3 In the HOPE trial,4 a significantly higher percentage of patients in the Oxbryta group demonstrated a hemoglobin response, defined as an increase of at least 1.0 g/dL. Oxbryta is approved for patients aged 12 years and older and is an oral tablet given once daily.

Two new medications for the treatment of DMD represent an advance in the treatment of this disease. Both Vyondys 53 and Viltepso bind to exon 53 of the dysfunctional dystrophin pre-messenger RNA, resulting in the skipping of exon 53.5,6 This allows for the production of a dystrophin protein, shorter than normal, but usable. The gene mutations that result in DMD vary: not all patients have mutations amenable to exon skipping. It is estimated that 8% of patients have mutations amenable to the skipping of exon 53.7 A similar mechanism is used for Exondys 51 (eteplirsen), which was approved in 2016 and skips exon 51. On the horizon is casimersen, which skips exon 45 – a new drug application is currently under consideration.

In August of 2020, a therapy for the treatment of spinal muscular atrophy (SMA) was approved, making it the third drug for this disease in less than 4 years. Evrysdi works by increasing inclusion of exon 7 in survival motor neuron 2 (SMN2) messenger ribonucleic acid transcripts, thus creating full length SMN protein. Trials in both infant-onset SMA and later-onset SMA were conducted to investigate efficacy.8 Patients in the infant-onset trial demonstrated a higher rate of sitting independently compared to typical disease progression. With this treatment, viability without permanent ventilatory assistance for children aged 23 months or older was higher than typical disease progression.9 Motor function scores compared to baseline were improved in patients with later-onset SMA.9 Evrysdi is the first oral medication for SMA.

New dosage forms


Valtoco is an intranasal diazepam, approved for the acute treatment of seizures in patients aged 6 years and older. Devices of 5 mg, 7.5 mg, and 10 mg are available and each Valtoco device contains 1 spray; doses of 5 mg and 10 mg are given with 1 spray of the 5 mg and 10 mg device respectively. Doses of 15 mg and 20 mg are given with 1 spray from each of 2 devices of 7.5 mg (15 mg dose) and 10 mg (20 mg dose).10 A second dose may be given at least 4 hours after the initial dose.

The new over-the-counter analgesic combination with ibuprofen and acetaminophen is the first of its kind in the United States. There is potential for overdose should patients use it in combination with acetaminophen or ibuprofen alone. A trial in pediatric patients aged 2-12 years is ongoing.

Drugs with new pediatric indications


Fiasp, a faster-onset version of insulin aspart, was approved in 2018 for use in adults, and is now approved for patients aged 2 years and older. It is formulated with niacinamide, which increases the rate of absorption, resulting in an onset about 5 minutes earlier than the original insulin aspart formulation. Results from the onset 7 trial demonstrated non-inferiority to insulin aspart in hemoglobin A1c reduction from baseline and change in 1-hour postprandial glucose in patients aged 1 to less than 18 years.11 Fiasp is approved for use in basal-bolus regimens, subcutaneous pumps, and intravenous use under the supervision of a healthcare professional.12

Originally approved in 2015 for the treatment of heart failure in adults, Entresto has now been granted approval for the treatment of symptomatic heart failure with systemic left ventricular systolic dysfunction in pediatric patients aged one year and older.13,14 This approval was based on 12-week results from the 52-week PANORAMA-HF trial, which compares Entresto with enalapril. Although the results were not statistically different between groups, improved outcomes were seen with Entresto.15


Treatment options for COVID-19 in pediatric patients remain limited. Veklury (remdesivir) was granted an Emergency Use Authorization (EUA) for the treatment of COVID-19 in adults and children by the FDA in May of 2020.16 A clinical trial of Veklury in children is ongoing. Veklury is available in a concentrated solution and lyophilized powder, both for intravenous injection.17 The manufacturer only recommends use of the lyophilized powder for patients 3.5 kg to less than 40 kg due to the higher amount of sulfobutylether-β-cyclodextran sodium salt in the concentrated solution for injection, resulting in a higher toxicity.

Convalescent plasma has also been granted an EUA from the FDA and is being used in the treatment of children and adults with COVID-19.18 Multiple vaccines are undergoing testing, and several trials include children.


The continuing trend of new drug approvals for children and novel dosage forms is encouraging for health care providers. Expanded labeling provides practitioners with tools to treat patients safely and effectively. Several drugs in the pipeline, as well as drugs approved for adults with ongoing pediatric trials will help to continue this trend.
