Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
We will conduct a parallel, double-blind, individually randomized, controlled trial of i) oral bovine lactoferrin (200mg or 400mg [as identified in the preceding 'Part 1' trial to find the effective dose for anemia correction]) compared to ii) standard oral iron supplements in anaemic pregnant women (haemoglobin <120 g/L & serum ferritin <30 µg/L) to assess impact on haemoglobin & iron status. The intervention (each capsule once daily) will be started as soon as pregnancy is detected and will be continued throughout pregnancy till delivery. Study personnel (field implementer and study physicians) will have monthly contacts with the enrolled women for monitoring compliance to intervention.
In the part 1 trial , we will conduct a non-inferiority, double blind, individually randomized controlled trial in non-pregnant women of reproductive age with iron deficiency anaemia (haemoglobin <120 g/L & serum ferritin <30 µg/L) to assess the haemoglobin and iron status in response to i) 200mg oral bovine lactoferrin, ii) 400mg of oral bovine lactoferrin and iii) standard oral iron supplements (60mg elemental iron). The aim of Part 1 trial is to find out the effective dose of bovine Lactoferrin (200 mg or 400mg) for anaemia correction compared to standard iron supplementation. The intervention (each capsule once daily) will be continued for 3 months. Study personnel (field implementer and study physicians) will have monthly contacts with the enrolled women for monitoring compliance to intervention.

Statistical methods / analysis
Estimated sample size is for a parallel two group superiority designed trial that will compare mean haemoglobin from each treatment group. The null hypothesis is that the haemoglobin response after one month of oral bovine lactoferrin (ML) is the same as with standard oral iron supplements (MI).
Ho: ML = MI
Ha: ML != MI (the means are not equal)
Assumptions:
• ML = 12.25 after 4 weeks of treatment
• MI = 12.00 after 4 weeks of treatment
• Expected standard deviation in each group = 0.85 (This is higher than part 1 because of increased variability of haemoglobin in pregnancy)
• Power = 0.90
• Alpha = 0.050 (two-sided)
The estimated required sample size per group is 243, giving a total estimated sample size of 486.
Since 20% of subjects are expected to be lost to follow-up, the total sample size is adjusted to 608.
This sample size would have 80% power to detect a difference in mean birthweight between the two treatment groups of 102g assuming a two sided alpha of 0.05, and standard deviation for birthweight in both groups of 400g.
This sample size would also have 80% power to detect a 41% relative difference in prevalence of low birth weight (25.0% in iron and 14.85% in lactoferrin treatment group) assuming a two sided alpha of 0.05. It would also have 80% power to detect a 56% relative difference in prevalence of preterm delivery (13.5% in iron and 6.0% in lactoferrin treatment group) assuming a two sided alpha of 0.05.
Calculation based on 'SSI': module to estimate sample size for RCTs in Stata version 14.

Analysis Plan
Participants who will receive at least one dose of supplement and at least one post-baseline efficacy assessment during the double-blind part will be included in the analysis. All analysis will be conducted at individual level. We will analyze participants categorized by the treatment group to which they will be allocated on an intention-to-treat (ITT) basis. The last day of follow up will be considered as outcome status for study participants who may be lost to follow-up without having the outcome of interest. To obtain the overall across-dose-range treatment (Lactoferrin and IFA supplements) effects, the average differences between log-dose slopes for percent changes from baseline in iron status and inflammatory biomarkers will be obtained in separate analyses (ANOVA) for all arms of part one. For safety analyses, descriptive statistics will be included for all parameters and an analysis of variance model (ANOVA) will be used for between-group (treatment arms) and within group (anaemic and mild anaemic) comparisons. For subgroup analyses, we will use Cox proportional hazard models (for mortality outcome), and other generalized linear mixed models (for preterm and low birth-weight outcomes) that will incorporate each of the major covariates. Statistical significance will be considered at p<0·05. Models will be able to evaluate the impact of the interventions by testing for interactions over time in all intervention groups. Analysis will be conducted to identify covariates that influence the response to interventions (based on household wealth, maternal education, or income).
