Damoctocog alfa pegol

Identification

Name
Damoctocog alfa pegol
Accession Number
DB14700
Description

In recent years, various extended half-life factor VIII and factor IX preparations have been studied and gained approval. In order to extend half-lives, techniques such as fusion to protein conjugates (Fc part of IgG1 or albumin), chemical modification (PEGylation), and protein sequence modification have been utilized.1

Also known as, BAY94-9027, Damoctocog alfa pegol is a longer-acting Factor VIII therapy formulated with polyethylene glycol (PEG) to reduce the number of infusions necessary to prevent bleeds in patients diagnosed with Haemophilia A.8,3,Label This product has been engineered by Bayer8 and a biological license application has been filed with the FDA in August 2017 and FDA approved in August 2018.13

Pharmacology

Indication

Indicated for use in previously treated adults and adolescents (12 years of age and above) with hemophilia A (congenital Factor VIII deficiency) for:

On-demand treatment and control of bleeding episodes Label, perioperative management of bleeding Label, and routine prophylaxis to reduce the frequency of bleeding episodes Label.

Pharmacodynamics

This agent is engineered to prolong blood FVIII activity while maintaining coagulation activity using PEGylation, where a PEG (Polyethylene glycol) molecule is continually attached to the factor VIII protein at a specific site 8, 3. This prevents and controls bleeding episodes associated with hemophilia A.

The aPTT is prolonged in people diagnosed with hemophilia A. The determination of aPTT is a conventional in vitro assay for assessing the biological activity of Factor VIII. Treatment with damoctogog alfa pegol normalizes the aPTT similar to that achieved with plasma-derived Factor VIII. The administration of this agent increases plasma levels of Factor VIII and can temporarily correct the coagulation defect that exists in hemophilia A patients Label.

Mechanism of action

This drug is a site-specifically PEGylated recombinant antihemophilic factor, which temporarily replaces the missing coagulation Factor VIII. The site-specific PEGylation in the A3 domain reduces binding to the physiological Factor VIII clearance receptors resulting in a longer half-life and increased AUC (area under the curve) Label.

The active protein, prior to conjugation is a recombinant B-domain deleted human coagulation Factor VIII (BDD-rFVIII) produced by recombinant DNA technology in Baby Hamster Kidney (BHK) cells Label.

Damoctagol alfa pegol is manufactured by site-specific conjugation of the BDD-rFVIII variant K1804C at the cysteine amino acid position 1804 (within the A3 domain) with a single maleimide-derivatized, 60 kilodalton (kDa) branched PEG (two 30 kDa PEG) moiety. The A3 domain was identified and selected for conjugation to provide both a continual coagulation activity and high PEGylation efficiency Label.

Toxicity

The most commonly reported adverse reactions in clinical trials in previously treated patients (PTPs) ≥ 12 years of age (≥ 5%) were headache, cough, nausea, and fever Label.

Hypersensitivity reactions, which includes severe allergic reactions, have occurred. Monitor patients for hypersensitivity symptoms. Should hypersensitivity symptoms occur, stop treatment with this agent and administer appropriate supportive treatment. Hypersensitivity reactions may also be related to antibodies targeted against polyethylene glycol (PEG) Label.

Development of Factor VIII neutralizing antibodies can also occur. If expected plasma Factor VIII activity levels are not reached, or if bleeding is not controlled as expected with the administered dose, perform an assay that quantifies Factor VIII inhibitor concentration Label.

Immune response to PEG, manifested as symptoms of acute hypersensitivity and/or loss of drug effect, has been observed mainly in subjects less than 6 years of age. Evaluate patients experiencing symptoms of hypersensitivity reactions in the absence of detectable Factor VIII inhibitors for possible bleeding or impaired recovery Label.
