Sponsor-declared trial summary
iron deficiency in adolescent girls
1. To evaluate the feasibility of Duroferon 100 mg administered on alternate days in combination with Iron Smart, compared with placebo plus Iron Smart, in adolescent girls with iron deficiency. 2. To evaluate the diagnostic performance of IRON-5 in identifying iron deficiency (ferritin <15 µg/L).

Trial design
CTIS Part I — objectives, methods, condition coding
Main objective
Scope: Diagnosis, Others
1. To evaluate the feasibility of Duroferon 100 mg administered on alternate days in combination with Iron Smart, compared with placebo plus Iron Smart, in adolescent girls with iron deficiency.
2. To evaluate the diagnostic performance of IRON-5 in identifying iron deficiency (ferritin <15 µg/L).
Secondary objectives 4
- To assess change in ferritin concentration from screening to follow-up.
- To assess change in haemoglobin, transferrin saturation (TSAT), vitamin B12 and 25-hydroxyvitamin D from screening to follow-up.
- To explore factors associated with iron deficiency (e.g. dietary patterns, BMI, menstrual characteristics, physical activity, socioeconomic status and country of birth).
- To explore factors other than iron deficiency associated with fatigue and self-rated QoL (e.g. vitamin B12/25-hydroxyvitamin D status, anxiety/depression and lifestyle factors).

Principal inclusion / exclusion criteria as submitted by sponsor
Inclusion criteria 6
- Student at Polhemskolan, Lund
- Age ≥15 years
- Post-menarcheal
- Written informed consent from the participant
- Written informed consent from legal guardian(s) if <18 years
- Serum ferritin <30 µg/L
Exclusion criteria 9
- Pregnancy
- Chronic inflammatory disease (e.g. rheumatoid arthritis, Crohn’s disease)
- Ongoing acute infection (e.g. tonsillitis, urinary tract infection)
- CRP >10 mg/L
- Current iron supplementation (except multivitamins)
- Anaemia (Hb <110 g/L if <18 years; <117 g/L if ≥18 years, according to regional reference limits)

- Clinically significant vitamin B12 deficiency requiring immediate medical evaluation or treatment (e.g. serum vitamin B12 <150 pmol/L).
- Use of medication known to interfere with iron absorption or cause clinically significant interaction with oral iron (e.g. fluoroquinolones, tetracyclines, bisphosphonates, levodopa, methyldopa, aluminium- or magnesium-containing antacids), defined as regular or daily use (≥3 times per week).
Endpoints
Primary and secondary outcome measures (English text)
Primary endpoints 1
- 1. Feasibility, including recruitment, retention, adherence and tolerability. 2. Diagnostic performance of IRON-5 (sensitivity, specificity, positive and negative predictive values, and ROC-AUC).
Secondary endpoints 4
- Change in ferritin concentration.
- Change in haemoglobin, TSAT, vitamin B12 and 25-hydroxyvitamin D from screening to follow-up.
- Associations between iron deficiency and selected factors (dietary patterns, BMI, menstrual characteristics including bleeding volume, menstrual pain and analgesic use, hormonal contraceptive use, physical activity, socioeconomic status and country of birth).
- Associations between fatigue and self-rated QoL and factors other than iron deficiency (e.g. vitamin B12 and vitamin D deficiency, anxiety/depression and lifestyle factors).
