ADULTS & ADOLESCENTS studies

Nuwiq®: In the GENA-01 study, efficacy of on-demand treatment (secondary endpoint) was assessed in adults and adolescents ages 12-65 years

Nuwiq®:Efficacy of on-demand treatment assessed in adults and adolescents

A total of 986 BEs was treated with Nuwiq in a prospective, randomized, actively controlled, cross-over, open-label, Phase II study of 22 adult and adolescent PTPs with severe hemophilia A. In total, 416 (42.2%) were minor, 566 (57.4%) were moderate to major and 3 (0.3%) were major to life-threatening. The severity for one BE was unknown. The mean on-demand treatment dose was 32.3 IU/kg. The median (range) number of infusions required to stop a BE was 1.0 (range 1–13). The mean duration of treatment of BEs overall was 1.1 days. The overall efficacy of on-demand treatment was evaluated based on criteria including improvement of objective signs of bleeding, number of infusions required to control the bleeding, and the time until bleeding improvement. The proportion of BEs with successful treatment (rated as “good” or “excellent”) was 94.4% (931/986 BEs). The rate of BEs successfully treated with just 1 or 2 infusions was 96.8% (954/986 BEs).

safety information

Indications and clinical use

Nuwiq® is indicated for the treatment and prophylaxis of bleeding in patients of all ages suffering with hemophilia A (congenital factor VIII deficiency).

Nuwiq® is also indicated for the peri-operative treatment of hemophilia A patients.

Pediatrics (< 12 years of age): Half-life (T1/2) and incremental in vivo recovery (IVR) are slightly lower in children than in adults and clearance is slightly higher. Efficacy in prophylaxis and the treatment of bleeds is comparable between children and adults. Data indicate that Nuwiq® is equally efficacious and safe in this population.

Contraindications

Nuwiq® is contraindicated for patients who are hypersensitive to the active substance or to any ingredient in the formulation or component of the container.

Relevant warnings and precautions

  • Transmission of infectious viruses can result from use of contaminated needles or accidental puncture with contaminated needles.
  • Strongly recommended that every time Nuwiq® is administered to a patient, the name and batch number of the product are recorded in order to maintain a link between the patient and the batch of the product.
  • All patients treated with Nuwiq® should be carefully monitored for the development of inhibitors by appropriate clinical observations and laboratory tests
    Allergic-type hypersensitivity reactions are possible.
