Infection in Pregnant Women, Mothers and their Children
IATT Overview

Established in 1998 and included 5 UN agencies working in HIV and health (WHO, UNICEF, UNFPA,
UNAIDS, World Bank)

2003: membership expanded to include global partners in PMTCT and HIV care and treatment in
children (23 agencies currently involved)

Provides a forum for:

But at the national program level fewer choices may be easier to implement:
•Simplifies guidance for HCW
•Streamlines procurement and supply chain
WHO Recommendations on ARV
Formulations
The principles that were followed in developing the WHO simplified tables include:

It is preferable to use an age-appropriate FDC for any regimen if available

Oral liquid or syrup formulations should be avoided especially if volumes are large

Dispersible tablets (or tablets for oral solution) are the preferred solid oral dosage forms

Young children should be switched to available solid oral dosage forms as soon as possible

Where adult formulations have to be used by children, care must be taken to avoid
underdosing. Adult tablets that are scored are more easily split. For those tablets that are
not easily split, WHO recommends that this be done in the dispensing pharmacy using
appropriate tablet cutters.

Some tablets such as LPV/r heat stable tablets are made in a special embedded matrix
formulation and should not be cut, split or crushed as they lose bioavailability.

Different dosing between morning and evening doses should be avoided.

Children have to be weighed at each clinic visit, and dose changes are required as children
grow and/or gain weight.
Availability of Drug Formulations
Impacts Implementation of Regimen
Recommendations
►
Two formulations of LPV/r are available: LPV/r 100 mg/25
mg heat-stable tablet for children >10 kg and LPV/r oral liquid
80/20 mg per 1 ml for use among infants.
►
TDF is currently available in 3 different formulations for use
across weight bands but a TDF-containing FDC is yet to be
developed

Low Volumes and Fragmentation are Problematic
Suppliers are limited by minimum batch requirements
► Manufacturers produce a minimum of generally several thousand packs of a particular product, called the
“minimum batch requirement”
► A product will not be produced until orders are meet the minimum batch requirement; otherwise,
supplier risks incurring losses from carrying stocks which fall below country shelf-life requirements
► Supply timelines can become highly unstable without ordering coordination

batch

The Market Risks
Market risks include…
Inability to procure low volume
formulations
• Highly fragmented low volume products
may not be supplied (e.g. non-essential
IATT list)
Limited registration coverage
• Suppliers have lower incentives to
register products in low volume markets
Limited new product options
• Creates further challenges to suppliers
realizing a return on investment for new
products
Who is at greatest risk…
• Low or medium volume country
• Procuring a large number of formulations
including multiple/redundant formulations
for the same patient population
• Procuring formulations or drugs considered
clinically inferior that most countries have
transitioned away from (e.g. liquid
formulations, ddI etc..)
Low Volumes of Multiple Redundant Formulations
Make the Paediatric ARV Marketplace Unstable

EXAMPLE: AZT+3TC+NVP regimen for 3 - 24.9 kg weight band
Product Fragmentation
• Multiple formulations

Until Recently, Guidance on Formulation Selection
For Paediatric ART Has Been Limited…
2013 WHO Treatment Guidelines

The 2013 WHO treatment guidelines provide specific guidance on preferred and alternative
first- and second-line regimens

However, guidance on specific formulation selection is not included
WHO Model Essential Medicines List (EML)

Identifies medicines that satisfy the needs of the majority of the population, to be available at
all times, affordable, and in appropriate dosage forms

Broad: organized into 29 therapeutic classes (e.g., antibiotics, anti-malarials…)

Next update: begins July 2014 and will be completed by Q2 2015

released
2011: First IATT Optimal Paediatric ARV Formulary
Created by IATT Optimal Paediatric Formulary List
In mid-2011, the IATT began a selection process for optimal paediatric
formulations given the following:

Proliferation of product choices and market fragmentation leading to instability in
the paediatric marketplace

Normative guidance was needed on the best options to deliver all required 1st and
2nd line regimens for paediatric HIV patients

An optimal formulary can serve as guidance for national programs, procurement
agencies, manufacturers
To be updated and revised when the WHO
updates regimen guidance
– or –
when new products and formulations
become available in low-income settings
IATT Paediatric ART Formulary: 2013 Revision
Optimal
• Minimum number of ARV formulations needed to
provide all currently recommended preferred and

regimens for all paediatric weight bands
• Formulations that may be needed during transition

The IATT List is a Living Document
That Will Be Reviewed on a Regular Basis
Revision triggers:
 Major Review every 2 years when WHO issues new
recommendations for paediatric ART
 Minor Review every 6 months to evaluate if:
► New and better paediatric ARV products available
► New paediatric drug/formulation SRA or WHO prequal approvals
► Actual or anticipated supplier side changes
► Significant shifts in HIV paediatric treatment practices
► Use of list (e.g., d4T-based formulations;
ABC/AZT/3TC; AZT syrup; DRV)
The List is Now Used by Multiple
Stakeholders
Paediatric ARV Procurement Working Group
(PAPWG) which now coordinates across:






Major agencies funding paediatric ARVs
Major buyers of paediatric ARVs
Ministries of Health, national drug regulatory agencies,
national HIV/AIDS programmes and procurement
offices
Civil society stakeholders in paediatric HIV
Community organization of people living with HIV
Manufacturers of paediatric ARVs
National Level Adoption

The IATT formulary is meant as a model
list

However since paediatric volumes are
small overall- global and regional trends
are critical to understand

Country programs should consider
options and select the formulations most
relevant to their needs
Steps To Consider For Country Adaptation of the
IATT Formulary

Why should countries rationalize their paediatric formularies

When should countries rationalize their formularies

Who are the stakeholders involved

How should the formulary be rationalized

What should be done after rationalization
Why: Country Advantages To
Optimization of Paediatric ARV
Formulary

Ensure quality of care (right doses and right drugs)

Ease administration to support adherence

Simplify prescribing practices

Streamline supply chain management

Potential for cost savings

Ensure demand so manufacturers continue to make paediatric
formulations

Incentivize manufacturers to invest in R&D for new drugs
When: After Treatment Guidelines
Have Been Updated
Consolidate
regimens used
► Ensure National paediatric ART recommendations are up to
date
► Optimization of regimens also essential to simplify treatment
► Identify regimens and products that can be phased out of
formulary (eg. d4T, ddI)

Optimization Opportunities
► Consolidate around optimal FDC formulations: e.g.
d4T/3TC/NVP 6mg/30mg/50mg triple FDC
► Remove outdated drugs: e.g. ddI
► Identify duplicative formulations: e.g. AZT 100mg capsule
► Limit use of liquid formulations : e.g. 3TC 50mg/5ml liquid
► Distinguish between optimal and non-essential formulations: e.g.
EFV 200mg scored tablet

procurement
►
Forecast & quantify paediatric ARVs
►
Generate supply plans (annually at a minimum)
►
Use the coordinated/pooled procurement mechanism or
follow the quarterly order cycle timeline
Key Points

The IATT Optimal Formulary is designed to guide selection and
procurement of paediatric ARV’s around a subset of optimal
products

Consolidation of demand stabilizes supplies of paediatric ARVS

Success will require global consensus, regional collaboration and
country implementation to ensure paediatric ARV’s will continue
to be available to children in need

Country process for optimization should include:


Regimen selection

Product selection

Coordinated procurement
PAPWG is the global body created to support and coordinate
procurement of paediatric ARV’s
