For manufacturers and marketers

01

Marketing-authorisation holders

02

Regional manufacturers

03

Distributors

Not a consumer offer, and not originator-branded product.

Laos FDF and LDC origin

Applies to finished dosage forms made in Laos — not to API manufactured in China.

01

WHO cGMP sterile site

Vials and pens are filled at a WHO cGMP facility in Laos, built for international inspection.

02

LDC is not legal advice

Laos is an LDC. That origin can matter in eligible markets under applicable IP rules. We state where we manufacture; freedom-to-operate stays with you.

How a program starts

Same sequence whether you take API, FDF, transfer, or a mix.

  1. 01

    Scope

    Form, markets, volume, and which layers you need. We confirm what we can stand behind before work starts.

  2. 02

    Align the file

    Specification, CoA format, and DMF / CTD expectations — written down while gaps are still cheap to close.

  3. 03

    Qualify supply

    API and/or sterile FDF against that spec. Audit findings stay in the same program plan.

  4. 04

    Deliver and hold

    First shipment, transfer and training if a receiving site will manufacture, then change control from one owner.
