For U.S. healthcare professionals only

Intended Use: myPKFiT is not indicated for the treatment of von Willebrand disease and should not be used for patients who have developed neutralizing antibody to FVIII products. myPKFiT is Rx only. For safe and proper use of the myPKFiT software, please refer to the complete instructions for use in the User Manual.

Please see the full intended use statement for myPKFiT below.

What is personalized PK-guided treatment?

PK-guided treatment utilizes a patient’s pharmacokinetic (PK) profile to create a dosing regimen that is personalized to their lifestyle. PK characteristics may be influenced by patient specific variables such as age and body weight.1

Patients who may benefit

Personalized PK-guided treatment may benefit patients who2,3:

  • Live an active, busy lifestyle
  • Participate in physical activities
  • Experience inadequate bleed control

myPKFiT for ADVATE helps enable PK-guided prophylaxis treatment1,2

myPKFiT is the first and only FDA-approved PK dosing software and patient app designed for ADVATE patients 16 years and older with a body weight of 45 kg or greater with hemophilia A.4

software’s reporting

Estimate a PK curve with as few as 2 measurable blood samples, compared to 9-11 as recommended by International Society on Thrombosis and Haemostasis guidelines.

Real-world experience with myPKFiT for ADVATE software2,3

  • myPKFiT for ADVATE can be a helpful tool for developing strategies intended to improve adherence, tailor prophylaxis, and provide patient education.
  • In a retrospective chart view, myPKFiT was used to estimate PK profiles for 27 patients with severe hemophilia A who had not received prior PK assessments
  • Limitations: this report included a small number of patients, and a study with a larger sample would be needed to confirm these results

A personalized approach to prophylaxis may help patients achieve their goals

Real-world study description7

A prospective, observational case series that utilized myPKFiT to estimate PK profiles in a subset of 22 patients recruited from 3 centers in Spain, aged 16-53 years old with severe hemophilia A, without inhibitors, on prophylaxis with ADVATE. Specifically, the study looked at the impact of myPKFiT use for prophylaxis adjustment, annual bleeding rate (ABR), and annual joint bleeding rate (AJBR).


Overall effect of myPKFiT on positive results seen in this short-term case series cannot be further assessed, considering the small sample of patients for statistical analysis (n=22).

A study with a larger sample would be needed to confirm these results.

ABR=annualized bleed rate; AJBR=annualized joint bleed rate; IQR=interquartile range.

Advate Selected Important Risk Information

CONTRAINDICATIONS: Patients who have life-threatening hypersensitivity reactions, including anaphylaxis, to mouse or hamster protein or other constituents of the product.

Please see additional detailed important risk information below.

Real-world experiences with myPKFiT

A prospective, observational case series found ABRs and AJBRs were reduced with a personalized prophylaxis regimen (utilizing myPKFiT) vs prior standard prophylaxis schedule in this patient subset.7

ABR using myPKFiT

50% reduced ABR after adjustment

(n=11; mean ABR reduction: -2.6 ± 1.4)

18.2 % increased ABR after adjustment

(n=4; mean ABR increase: 1.0 ± 0.0)

AJBR using myPKFiT

54.5% reduced AJBR after adjustment

(n=12; mean AJBR reduction: -2.0 ± 1.2)

9.1% increased AJBR after adjustment

(n=2; mean AJBR increase: 1.0 ± 0.0)

ABR=annualized bleed rate; AJBR=annualized joint bleed rate; IQR=interquartile range.
