• HIGHER RISK OF ADVANCED LIVER DISEASE • Lower risk of HCV transmission


HCV Guidance Recommendations for Testing, Management, and Treatment • Recommendations for When and in Whom to Initiate Treatment – Treatment is recommended for ALL patients with chronic HCV infection, except those with a short life expectancy that cannot be remediated by treating HCV, by transplantation, or by other directed therapy

• Goal of Treatment – Reduce all-cause mortality and liver-related adverse health consequences, including ESLD and HCC, by the achievement of virologic cure

HCV Testing in Baby Boomers and PWID USPSTF and AASLD/IDSA Recommendations Recommendations • One-time HCV testing is recommended for persons born between 1945 and 1965 (birth cohort; baby boomers) without prior ascertainment of risk1,2,a • All individuals outside of the birth cohort who have an HCV risk factor should be tested1 – Persons with continued risk of HCV exposure should be tested periodically2 – Evidence on how often testing should occur in these persons is lacking

• Annual HCV testing is recommended for PWID and for HIV-infected men who have unprotected sex with men2 • At least annual HCV-RNA retesting following successful HCV treatment or spontaneous viral clearance is recommended for sexually active MSM and PWID with recent or ongoing injection drug use2 − More frequent risk-based testing is recommended, if indicated − HCV Ab will remain positive in the majority of people and should not be used to test for reinfection Ab, antibody; USPSTF, US Preventive Services Task Force. aRegardless of country of birth (AASLD/IDSA). 1.

Linkage and Engagement in HCV Care The Patient’s Reality1,2

Limited access to health care Poor quality of life Alcohol consumption Use of multiple substances Homeless or living in temporary accommodations (shelter, prison) Poorly educated (secondary education or less)

“I am treated like a criminal and this makes it hard to take care of my health.” “There are no friendly health care services near me where I live.” “I would like to give up drugs, but I cannot get help.” “I cannot get opioid-substitution therapy/syringes because it is illegal.” “Health care workers do not trust me, as if I just want drugs.” “Without clean needles and syringes, I have to share.”

What Does Your Patient Need to Know About HCV? • HCV is a serious and potential deadly disease that is associated with high risk of cirrhosis and liver cancer • The virus can be transmitted to others through – Shared use of drug paraphernalia or other blood-contaminated objects (eg, razors) – Sexual activity, especially among MSM – Pregnancy; maternal-child transmission

• Cost should not be a barrier to initiation of HCV treatment! • HCV treatment is highly effective, including in PWID on MAT or continuing injection drug use; and in HIV/HCV coinfection – – – – –

Treatment will be managed by an HCV-care provider Treatment may be as simple as 1−3 pills per day, and as brief as 8−12 weeks in duration The medications are well tolerated The full treatment course must be completed Post-treatment follow-up is essential

• HCV reinfection is possible — risk reduction following treatment is critical! AASLD. HCV Guidance: Recommendations for Testing, Managing, and Treating Hepatitis C. Last updated September 2017. http://www.hcvguidelines.org/evaluate/when-whom. Accessed May 27, 2019.

Harm Reduction

Reducing the Negative Consequences of IDU1 • MAT – Methadone, buprenorphine, other opiate substitutes – Reduction in the number and severity of relapses due to opiate use

• NSPs – Reduction in incidence of HCV infection and reinfection

• Naloxone access – A parenterally administered medication that rapidly reverses the effects of opioids – Training for persons at risk and individuals likely to witness an OD2

• Mental-health services colocated with MAT/NSP3 • Education, counseling, and outreach

Harm Reduction Does Not End With Cure Reinfection in PWID: Realities and Strategies

• There will be cases of HCV reinfection1 – Risk increases with higher injection frequency – But there is no overall difference in reinfection rate, even among individuals currently injecting or on MAT

• But we must concomitantly scale up harm-reduction measures

SELECTED MODELS AND STUDIES Pharmacy-Based HCV-Related Services


Model: Large Retail Pharmacy Point-of-Care HCV Testing1,2

• Background: POC testing can increase the number of individuals diagnosed; however, linkage to care which remains a major challenge, is essential for improving patient outcomes • Design – Participating markets were selected within lower-income areas of major metropolitan cities – Each market had 5 pharmacy sites; testing was performed at each site once weekly – 1 phlebotomist was assigned per market; each was individually trained on administration of HCV-Ab testing and interpretation of results – Individuals were recruited by direct advertising at each store

• Primary objective: To identify HCV prevalence using birth cohort and high-risk factor screening at large retail pharmacies and link HCV-Ab+ individuals with a pathway to care POC, point of care. Kugelmas M, et al. Gastroenterol Hepatol (N Y). 2017;13(2):98-104.

The London Joint Working Group Pilot Study Conclusions

• The pilot demonstrated that providing HCV tests within NSP community pharmacies can be an effective tool for identifying HCV+ PWID and referring them for further testing and treatment • Treating with HCV antiviral therapy directly in NSP pharmacies has the potential for higher uptake of treatment by service users testing positive for HCV • Educating service users regarding HCV treatments and safer injection practices should be integral to any pharmacy testing program • Practical recommendations – Pharmacy training is essential prior to HCV testing going live – Pharmacy training should include practical demonstrations: both testing and counseling – All pharmacy counter staff should be trained HCV Testing in NSP (Needle and Syringe Provision) Community Pharmacies Pilot (Phase 1).

Study: The Rural Outpatient Setting

The Pharmacist’s Roles in HCV Care Under Collaborative Drug Therapy Management (CDTM) • A federal study of Indian Health Service (IHS) facilities to identify and address gaps in HCV treatment • Clinical pharmacists’ roles under the CDTM – Provide comprehensive HCV care under the supervision of a physician – Screen for and address lifestyle factors and comorbidities that may adversely affect HCV treatment outcomes – Act as case manager for patients diagnosed with HCV; link to other services – Provide other pharmacist services; eg, medication counseling, DDI identification, treatment monitoring Geiger R, et al. J Prim Care Community Health. 2018;9:1-5.


IHS Facilities Study

Screening to Diagnosis: Study Results and Conclusions • Key findings: screening to confirmatory testing

HCV Ab+ (N=1789)

– 1789 patients identified as HCV Ab+ – 77% (1381) had a confirmation test performed – 67% (929) were positive for HCV RNA

• These data indicate that rural clinics can be successful in providing HCV diagnosis • Pharmacists can play a key role in rural HCV clinical services Geiger R, et al. J Prim Care Community Health. 2018;9:1-5.

Study: An HIV/HCV Primary Care Model

The Pharmacist’s Role in the Multidisciplinary Team • One of the first studies to identify the important role of pharmacists in increasing access to HCV treatment in difficult to treat populations • A higher proportion of patients received treatment in the primary care vs the specialty model – Similar rates of psychiatric disease – Higher frequency of substance use disorder in primary care model

• Cure rates in the primary care model were similar to those in the specialty model

Cachay E, et al. AIDS Research and Therapy. 2013;10(9):1-12.


Concluding Comments

Critical Opportunities for Pharmacists • Pharmacists are ideally placed in diverse practice settings to actively participate in HCV elimination • Community pharmacists can form effective relationships with patients in difficult-to-reach subpopulations and implement HCV testing, identification of at-risk individuals, education, and linkageto-care strategies • Pharmacists can extend HCV treatment capacity and impact through collaborative multidisciplinary care models and provide pharmacist-based services that enhance care
