About
The objective of the study is to compare the safety and gastrointestinal tolerability of ferric maltol oral suspension and ferrous sulfate oral liquid in children and adolescents aged 2 years to 17 years, and assess the safety and tolerability of ferric maltol oral suspension in children 1 month to less than 2 years, in the treatment of iron deficiency anaemia during the 12 weeks treatment period.
Full description
The study is a randomised, Open-label, Active-controlled, Multicentre, Comparative Study to Evaluate the Safety and Efficacy of Ferric Maltol (Iron (III)-Maltol Complex) (ST10) Oral Suspension Compared to Ferrous Sulfate Oral Liquid in Children and Adolescents Aged 2 to 17 Years With Iron-deficiency Anaemia, Incorporating a Single Arm Study in Infants Aged 1 Month to Less Than 2 Years.
Approximately 110 male and female children from 1 month to 17 years of age, with iron deficiency anaemia.
Subjects aged 2 to 17 years will be 1:1 randomised to ferric maltol and ferrous sulfate, with 49 subjects in each arm. Subjects then will be further divided into 2 age groups: 2 yrs - 9 yrs and 10 yrs -17 yrs. A minimum of 18 subjects must be recruited into the 2 yrs - 9 yrs and 10 yrs - 17 yrs age groups and a minimum of 25% of either sex must be recruited.
A maximum of 12 subjects will be recruited in the 1 month to less than 2 years age group. They will only be assigned to the ferric maltol group, once there is evidence of absorption, metabolism of serum iron and elimination of maltol from the Pre-assignment PK samples by showing plasma maltol return to baseline, confirming no accumulation of maltol or maltol glucuronide, they will continue on to the 12 weeks treatment phase.
Design: The study will comprise of the following stages:
Investigational Product Product: Ferric maltol oral suspension: oral suspension containing 30 mg elemental iron, in the form of 231.5 mg ferric maltol, in 5 ml suspension.
Ferric maltol oral suspension will be taken every morning and evening at least 30 minutes after a meal. Dosing will be supervised by the parent/legal guardian for children/adolescents throughout the treatment period and recorded on a dosing diary.
Ferric maltol bottles will be labelled for clinical trials use and each bottle will have a unique bottle number which will be utilised in the randomisation procedure.
A final eligibility evaluation must be conducted immediately prior to randomisation.
Reference safety information will be the Investigator Brochure.
Comparator therapy: Ferrous sulfate 125 mg/ml (25 mg/ml elemental iron) oral liquid or equivalent dose will be administered under this protocol. Dosing will be supervised by the parent/legal guardian for children/adolescents throughout the treatment period and recorded on a dosing diary.
Reference safety information will be the currently approved summary of product characteristics.
Statistical methods: The study will include 98 subjects in the 2 - 17 years age group, randomised 1:1 between ferric maltol and ferrous sulfate: 49 in each treatment group. The study will also include up to 12 subjects in the 1 month to less than 2 years age group.
Safety and gastrointestinal tolerability will be compared between ferric maltol oral suspension and ferrous sulfate oral liquid via summaries of treatment emergent adverse events (TEAEs), treatment emergent serious AEs (TESAEs) and treatment-emergent AEs (TEAEs) leading to premature discontinuation of study drug.
Efficacy of ferric maltol will be assessed via the change in Hb concentration from baseline to week 12, summarised as the mean across all subjects, with 95% confidence interval.
For the PK analysis, all analytes in serum will be summarised per PK day, for children and adolescents aged 1 month to 17 years receiving ferric maltol.
Population PK analysis will be conducted for maltol and maltol glucuronide in plasma and for serum iron and TSAT in children and adolescents aged 1 month - 17 years.In addition, all analytes in urine will be summarised per PK day, for children aged 1 month to less than 2 years.
Full details of the statistical analysis, including the analysis of PK endpoints, will be specified in the statistical analysis plan (SAP).

Inclusion criteria
Haemoglobin thresholds define anaemia by age and gender:
Children (1 m - < 5 yrs) <11.0 g/dl Children (5 yrs - < 12 yrs) <11.5 g/dl Children (12 yrs) <12.0 g/dl Female child (≥13 yrs) <12.0 g/dl Male child (≥13 yrs) <13.0 g/dl and
Ferritin thresholds define anaemia by:
ferritin <30 µg/L, or ferritin <50 µg/L with transferrin saturation (TSAT) <20%, 4. Female subjects of childbearing potential must agree to use a highly effective method of contraception (which includes complete abstinence) until study completion and for at least 4 weeks following their final study visit. Highly effective contraception is defined as a method which results in a low failure rate, i.e., less than 1% per year when used consistently and correctly, such as implants, injectables, some intrauterine contraceptive devices (IUDs), a vasectomised partner and oral contraceptive medications.
The need for contraception and compliance with contraception requirements will be assessed at every visit for adolescent patients, and urine pregnancy testing will be performed at each visit for female subjects of childbearing potential.
Exclusion criteria
Subject with anaemia due to any cause other than iron deficiency, including, but not limited to,
a. Untreated or untreatable severe malabsorption syndrome
Subjects who have received prior to Screening:
Subjects with vitamin B12 or folic acid deficiency as determined by the central laboratory screening results. Subjects may start vitamin B12 or folate replacement and rescreen after at least 2 weeks.
Has concomitant disease that would significantly compromise iron absorption or absorbed iron utilization such as swallowing disorders and/or extensive small bowel resection.
History of active peptic ulcer
Has chronic renal disease (eGFR <60 mL/min/m2), as assessed at Screening based on serum creatinine.
Known hypersensitivity or allergy to either the active substance or excipients of ferric maltol or ferrous sulfate.
Has a known contraindication for treatment with iron preparations, e.g. haemochromatosis, chronic haemolytic disease, sideroblastic anaemia, thalassemia, or lead intoxication induced anaemia.
Impaired liver function as indicated by alanine aminotransferase (ALT) or aspartate transaminase (AST)>2.0 times upper normal limit as measured at the Screening visit.
Active acute inflammatory disease, including IBD flare or disease exacerbation, which in the opinion of the Investigator, is clinically significant.
Active chronic or acute infectious diseases requiring antibiotic treatment.
Pregnant or breast feeding.
Concomitant medical conditions with extensive active bleeding, other than menstrual cycles; subjects who suffer from menorrhagia may be included at the Investigator's discretion.
Scheduled or expected hospitalisation and/or surgery during the course of the study
Participation in any other interventional clinical study within 28 days prior to Screening.
Diagnosed to be COVID-19 positive by (SARS-CoV-2-RT-PCR positive) within 28 days prior to screening.
Cardiovascular, liver, renal, hematologic, psychiatric, neurologic, gastrointestinal, immunologic, endocrine, metabolic, respiratory or central nervous system disease that, in the opinion of the Investigator, may adversely affect the safety of the subject and/or objectives of the study drug or severely limit the lifespan of the subject.
Any other unspecified reason that, in the opinion of the Investigator or the Sponsor make the subject unsuitable for enrolment.
