Corifact: how international patients access US-sourced specialty supply

This page is informational, not medical advice. Always work with a licensed treating physician on prescribing decisions. Reserve Meds does not make insurance or pharmacy-assistance-program promises.

Quick orientation

Corifact (Factor XIII concentrate (plasma-derived, human)) is sponsored by CSL Behring and received first US FDA approval in 2011. It is delivered as intravenous infusion, monthly prophylaxis. The US label covers routine prophylactic treatment of congenital Factor XIII deficiency and peri-operative management of surgical bleeding in adults and pediatric patients with congenital Factor XIII deficiency. Mechanistically, Corifact is a pasteurized concentrate of human Factor XIII purified from pooled plasma.

US wholesale acquisition cost (WAC) is the published US specialty-distribution list price and is not the same as a single-payer negotiated price. Corifact US WAC commonly produces annual drug-only costs in the high six figures depending on weight and dosing cadence. Patient out-of-pocket via cross-border supply is the US WAC plus logistics, IOR / customs, translation, and a Reserve Meds concierge fee; it is not a route to local-formulary pricing.

Mechanism of action

Corifact is a pasteurized concentrate of human Factor XIII purified from pooled plasma. It restores plasma Factor XIII activity in patients with congenital deficiency, allowing fibrin clots to be properly cross-linked and stable. Because it contains both A and B subunits, it covers the broader congenital Factor XIII deficiency population beyond isolated A-subunit deficiency.

Why Corifact routes via cross-border NPP internationally

Congenital Factor XIII deficiency is extremely rare and most regional hemophilia treatment centers across MENA and South Asia carry limited supply of dedicated Factor XIII concentrate. Off-label cryoprecipitate or fresh-frozen plasma is sometimes used regionally as a substitute, with meaningful clinical drawbacks. Patients who require dedicated Factor XIII concentrate for prophylaxis or peri-operative cover typically route via named-patient import.

The patterns that produce cross-border demand for Corifact are consistent across destination countries: meaningful registration lag relative to the US label, indication-specific dosing complexity that makes substitution clinically risky, payer denial patterns that exclude newer or expanded indications, and the global specialty distribution model in which the originator manufacturer routes specialty supply through a small number of authorized US wholesalers. Reserve Meds sits inside that authorized supply lane, not outside it.

How Reserve Meds coordinates supply

Every Corifact case follows the same physician-led, document-first workflow:

1. The treating physician issues a prescription and clinical justification letter.
2. Reserve Meds clinical and regulatory review assesses indication fit and destination-country pathway eligibility.
3. Country-specific named-patient or personal-import documentation is prepared, translated where required, and submitted to the destination-country regulator under the local lawful import framework.
4. Supply is sourced from a DSCSA-compliant US specialty wholesaler with full serial traceability (a federal track-and-trace requirement) and unbroken chain of custody from US warehouse forward.
5. Cold-chain handling is validated where applicable; temperature is monitored end-to-end with audit logs.
6. Shipment is coordinated to the patient's treating physician or hospital pharmacy, not directly to consumers.

Reserve Meds does not handle controlled substances. We do not promise pharmacy assistance program enrollment, manufacturer copay support, or insurance reimbursement; those are different commercial frameworks aimed at US-domiciled patients.

Common cross-border destinations

Corifact cross-border demand concentrates in markets where US specialty supply is the most reliable path to the labeled indication. We publish destination-country deep-dives where local matrix cells exist; the rest are coordinated case-by-case on the same physician-led workflow.

Across each of these destinations, three structural patterns repeat. First, the local regulator maintains a named-patient or personal-import framework precisely so clinicians can reach a labeled US therapy for individual patients whose case cannot wait for full local registration. Second, that framework is document-driven, which means the work of cross-border access is the work of preparing a defensible clinical and regulatory dossier rather than chasing inventory. Third, the destination-country specialist (the treating physician) signs the case in; Reserve Meds operates on top of that signature, not in place of it.

Real cost picture

Annual drug-only cost commonly runs in the high six figures depending on body weight and dosing cadence. Cold-chain logistics, customs, IOR, and translation costs apply. Reserve Meds quotes firm pricing after the hemophilia-center dossier and labs plan are reviewed.

A formal Reserve Meds quote breaks out: drug cost at US WAC; cold-chain 3PL handling where applicable; IOR, customs, and destination-country regulatory fees; certified translation of physician documentation; and a tiered Reserve Meds concierge fee layered on the drug cost rather than per-dose. The indicative range above is for orientation; a firm quote is issued after physician documentation is reviewed.

Reserve Meds does not charge intake deposits. Patients pay the firm-quoted amount in full only after accepting the quote, with a defined refund posture for procurement failure or gross negligence as set out in the engagement documentation. Delivery or transit-failure outcomes are handled via insurance and replacement coordination rather than refund, because once a US procurement chain is committed, the drug is committed.

Manufacturer context and global distribution

Corifact is manufactured by CSL Behring. Like most US specialty therapies, it is routed through a narrow set of authorized specialty wholesalers under DSCSA (Drug Supply Chain Security Act) track-and-trace rules. That is the same supply lane US specialty pharmacies use; cross-border named-patient access works by attaching destination-country regulatory documentation to a shipment that originates inside that authorized lane, not by sourcing outside it. Counterfeit and parallel-trade exposure is concentrated outside that lane, which is precisely why Reserve Meds will not source from secondary or grey-market channels regardless of price.

Serial-number traceability is preserved end-to-end. Every Corifact pack or vial carries the US wholesaler's lot and serial-number documentation forward into the destination-country regulatory submission, which is what allows the destination regulator to verify provenance on inspection.

What your physician provides

For Reserve Meds to coordinate Corifact, the treating physician provides a treating-hematologist prescription, a clinical justification letter documenting confirmed congenital Factor XIII deficiency and bleeding history, Factor XIII activity assay results, an infusion plan, and license verification. Reserve Meds does not substitute for treating-physician judgment, does not prescribe, and does not advise on individual patient suitability; that is the treating physician's role.

Common questions

How is Corifact different from Tretten?

Corifact is plasma-derived and covers the broader Factor XIII deficiency population (A- or B-subunit). Tretten is recombinant A-subunit only.

Is there a pathogen-safety concern with plasma-derived product?

Corifact undergoes pasteurization and pathogen-reduction steps; the regulatory safety profile is well-characterized. Inhibitor and viral-serology surveillance is part of monitoring.

Does Corifact require cold chain?

Yes. Refrigerated storage is required until reconstitution.

How often is Corifact given?

Monthly IV prophylaxis is the standard regimen; peri-operative dosing is calculated separately.

Is FFP or cryoprecipitate a real substitute?

They can provide some Factor XIII activity but are not equivalent on dose precision or pathogen-safety profile and are not a long-term prophylaxis solution.

Indicative timing

Time-to-first-dose for Corifact is dominated by destination-country regulatory turnaround on the named-patient or personal-import submission, not by US procurement (which is typically days, not weeks, for an authorized specialty wholesaler with serialized stock). In faster markets (UAE Ministry of Health and Prevention named-patient track, Saudi SFDA named-patient track), the regulatory clock is commonly under 4 weeks when the dossier is complete on first submission. In slower markets or where translations and additional attestations are required, the regulatory clock can extend to 6 to 10 weeks. Reserve Meds frames every Corifact timeline as an indicative range with a defined gating event (regulator acknowledgement), not as a guaranteed delivery date.

Subsequent cycles are materially faster than the first cycle because the regulatory file, physician credentials, and import authorization are already on record. For chronic-use therapies like Corifact, the first cycle carries the regulatory overhead; the rest is logistics.

Where Reserve Meds fits in

Reserve Meds is the named cross-border coordinator. A dedicated patient coordinator owns the case from intake through delivery, the clinical and regulatory teams handle the document chain, and a DSCSA-compliant specialty wholesaler is the source of every vial or pack. We work in service of the treating-physician relationship, not around it.

Patients deal with one named coordinator from intake through delivery. Physicians deal with a clinical-and-regulatory contact who speaks the language of the destination regulator and of US specialty pharmacy. That single-point-of-contact structure is deliberate: cross-border specialty access fails most often at the seams between parties, not inside any single step, and Reserve Meds is built to own the seams.
