Program Overview This program will provide education for hematologists, nurses, pharmacists, and other healthcare providers involved in hemophilia care on how to better determine individualized prophylaxis strategies for patients with severe hemophilia. In addition, the multidisciplinary team will hear about strategies to monitor the effects of prophylaxis and adherence to therapy to ensure optimal and cost-effective patient management. The expert faculty will discuss critical time points in a patient’s life that are associated with changing treatment regimens and adherence so that prophylaxis can be continued or initiated in children and adults. Implementing appropriate strategies to improve adherence can lead to successful outcomes in both pediatric and adult patients on prophylaxis. In addition, how different HTCs design and implement prophylactic regimens, address challenges with adherence, and utilize prophylactic treatment to manage non-standard clinical situations (eg, activity-related prophylactic infusions, management of microbleeds) will be discussed.

Target Audience The proposed educational initiative is targeted toward hematologists and hemophilia specialists, nurses, physicians-in-training, pharmacists, and other members of the comprehensive care teams at HTCs, as well as professionals in managed care, specialty pharmacy, and home health care settings.

Learning Objectives Upon completion of this educational activity, participants should be better able to:

• Identify the clinical benefits of and barriers to prophylaxis vs. on-demand treatment for management of patients with congenital hemophilia

• Review approaches to hemophilia prophylaxis, including assessment of response to prophylactic treatment, to better individualize patient prophylactic regimens

• Evaluate the potential role of newer therapeutic agents, including extended half-life factor concentrates, in prophylactic regimens

• Incorporate strategies to promote adherence to hemophilia prophylaxis for improved patient outcomes

• Adherence by the patient: caregiver may ‘tailor’ treatment for better results

Considerations for Comprehensive Care Team

treatment for better results– Child with venous access challenges– Adolescent – Adult with long-term care challenges

• Comorbidities– Hepatitis C/HIV– Arthritis/heart disease/kidney failure

• Medication use (over the counter, herbal, diet)

• Level of physical activity

Considerations for Comprehensive Care Team

Activity Level Considerations*

Very active lifestyle (athletes, active adults)

• Multiple peaks are beneficial– Use standard half-life factors 3-4x per week

(sometimes even more)• Troughs are less important

Sedentary/less active • Troughs are key to preventing bleedsSedentary/less active Troughs are key to preventing bleeds• Peaks for high-risk activity not important

– An extended half-life factor is more convenient and provides same trough level

* Based on expert opinion.

• Pharmacokinetic profileAd lt hild

Considerations for Comprehensive Care Team

– Adult vs child– Obese patients– Previous inhibitor patients

• Relationship with HTC staff (trust)

• Social factors (attitudes, beliefs)( , )

• Literacy level of patients

Current MASAC Recommendations

• Should be considered optimal therapy for individuals with severe hemophilia A or Bindividuals with severe hemophilia A or B

• Should be instituted early (before onset of frequent bleeding)

• Goal: keep trough levels > 1%

• Patients may continue to benefit from• Patients may continue to benefit from prophylaxis throughout their life

– Weight– Bleeding pattern– Trough level

• More recent– Annualized bleeding rate (ABR)– Individual pharmacokinetics (PK)

Pharmacokinetic Studies (PK)

• Hemophilia treatment well suited to optimization by PK studiesstudies

• “Tailored” dosing: based on patient’s rAHF-PFM PK (infusion interval, estimate t1/2, and recovery)

• PK study: performed after 3-5 half-life washout period– Dose product to 100%

– Factor activity measured at various time points

• Superior results to episodic treatments with respect to annualized bleeding rate and qualify of life measures

• Limited “dangerous” physical activity

Infancy, Toddlerhood, and Preschool

• Risk for falls/injuries

• Venous access issues

• Options include:

Regimen DosingFull-dose 3-4x per week

Tailored dosing • Aiming for a set trough• Requires PK studies

Step-up

• Physical activities/sports often begin and/or become more serious at this age

School Age

become more serious at this age

Physical Activity ConsiderationsActive, athletic children • May need more peaks per week

– Full-dose prophylaxis with 3-4x per week dosing

Less active children • Can use a less intense regimen– PK-tailored dosing aiming for a low trough– PK-tailored dosing aiming for a low trough

(1%-3%)– Less frequent dosing regimen (2x a week

regardless of trough)– Consideration for extended half-life factors

with even less frequent dosing

Forgetfulness• Dealing with it on a daily basis• Dealing with it on a daily basis• Social/family stresses (lack of discipline)• Costs• Transition to adulthood

– Lack of supervision– Lack of commitment

• Poor venous access• Risk of complications• Adults: unwillingness to allow HTC to interfere with their

Hemophilia Physicians’ Perceptions of Adherence to Prophylaxis

Adherence is suboptimal (N = 59)

• ~60% infuse more than 75% - 80% of recommended infusions

• 54% believed that 76% - 100% of their patients infuse prophylactically > 80% of dosesdoses

• 42% believed that 51% - 75% of patients infuse > 80% of doses

Ways to Improve Adherence: Patient’s Perspective

• Education about prophylaxisT ki h l i• Tracking prophylaxis– Diary/log– PC/palmtop database

• Improvements in factor• Contracts• Communication

– Internet dialog page– More frequent visits– Reminder telephone calls

Thornburg C. J Coag Disorders. 2010;2(2):1-6.

Ways to Improve Adherence:Healthcare Provider’s Perspective

• Education about prophylaxisP t it t d i hibit– Promote it as a way to decrease inhibitor formation, enhance participation in physical activities, decrease subclinical bleeds

• Improve ease of venous access– Psychological interventions to decrease anxiety

w/ PIVw/ PIV– Training for independence

• Individualized therapy

How Healthcare Providers Can Change Adherence Patterns

• Health professionals’ job satisfaction (communication/body language)(communication/body language)

• Discuss patients’ beliefs (motivational Interviewing)

• Keep regimens simple; fit into patient’s lifestyle

• Assess available social support, family structure

• Screen and refer for depression

• Just trying to convince them that treatment is good for them is unlikely to work

• Affordable Care Act (ACA) eliminated some of the barriers:

– Lifetime caps removed

Healthcare Coverage

Lifetime caps removed

– Insurance coverage cannot be dropped for pre-existing conditions

• Navigate through various coverages; remember to ask:– Premium costs and coverages (medical versus pharmacy)

– Copays and deductibles

– Direct cost to consumer: out of pocket costs
