Workshop Background
- Oral Therapies in Lymphoma
Workshop convened Fall 2015 in Washington, D.C.
- First multi-stakeholder meeting
to explore changing nature of lymphoma/CLL treatment, implications of oral therapies
- Expert presentations and
discussion outlined key issues,
- pportunities, and challenges
facing the community
Workshop Findings
- Three core themes emerged from the 2015 workshop:
- Impact of oral therapies on a heterogeneous disease like lymphoma
is vast and therefore can serve as a case study for other cancers
- Numerous challenges including adherence, monitoring, toxicity
management, patient education, and cost
- Research plays essential role in ensuring HCPs and patients have
the information and treatment choices required to maximize
- utcomes and ensure quality of life
Workshop Findings
- Adherence focus areas:
- Challenges related to adherence highly complex and difficult to
quantify
- Numerous barriers exist to accurately measure adherence
- Existing methods of adherence assessment and emerging
technologies could eventually play role in both measuring and supporting patient adherence
- Little data exists on the clinical impact of adherence
Program Goals
- Review epidemiology/forms
nonadherence, methods of adherence assessment, and barriers to accurately measuring adherence
- Identify primary causes of
nonadherence as well as related adherence interventions and tools
- Discuss the design and
implementation of studies focused
- n adherence in lymphoma/CLL

Overview
Review rates and correlates of adherence to oral chemotherapy Discuss development of a mobile app intervention to improve symptom monitoring and adherence to
- ral chemotherapy
Describe results of an randomized controlled trial of the mobile app intervention
Background
The increased use of oral chemotherapy has revolutionized cancer care through improved:
- Disease outcomes and patient survival
- Convenience of treatment administration
- Quality of life by avoiding problems with IV infusion
However, patients generally receive less supervision and support for adherence and monitoring of side effects as opposed to directly-
- bserved infusion chemotherapy.
- Documentation of
- ral versus IV
chemotherapy plans in 175 patients with metastatic NSCLC
- ASCO Quality

- Patients prescribed oral chemotherapy experience
concerning problems with adherence.
- A variety of psychosocial and treatment factors are
associated with adherence.
- Despite the advantages of oral chemotherapy,
symptoms and side effects occur at high rates, especially fatigue, drowsiness and sleep disturbance.
Conclusions
Conclusions
- Through a multi-step process involving numerous stakeholders,
we successfully developed a smartphone mobile app to support patients prescribed oral chemotherapy.
- In the overall sample, the mobile app was generally not
associated with outcomes but lead to improvements in self- reported social wellbeing compared to usual care and marginally significant improvement in satisfaction with interpersonal treatment with clinicians.
- Intervention effects on outcomes were stronger in patients who
reported poor adherence and high anxiety at baseline.

Motivation
§ Targeted oral anticancer (OAC) medications have transformed cancer care
§ OAC medications offer many potential advantages over traditional IV chemotherapy − Superior effectiveness − Convenient home-based treatment − A sense of control over treatment − Avoid IV infusions, trips to hospital § Potential downsides of OAC medications − Complex treatment regimens, often in addition to other medication regimens − OAC medications require strict adherence to be effective − Patients/caregivers are responsible for symptom management − Financial burden − Difficulties acquiring OAC medication
43
Adherence to OAC Medication is Critical for Achieving a Therapeutic Response
§ Many oral agents are cytostatic § Optimal adherence: correct drug, correct dose, correct time, correct conditions § Imatinib adherence in CML <80% → no molecular response § Imatinib adherence in GIST → 2-year progression free survival 80% in continuous group vs. 16% in interrupted group § Full dose ibrutinib adherence in CLL → improved PFS in patients missing < 8 days of treatment compared to patients missing > 8 consecutive days of treatment § Suboptimal adherence → toxicity, more physician visits, higher hospitalization rates, unnecessary treatment changes, breakdown in the patient-provider relationship, increased health care expenditures, biased response rates in clinical trials § OAC medication adherence estimates vary widely: 20% - 100%

- Regimens are complex and often in addition to other medications
- Adherence is inversely related to dosing complexity
- “…clinicians must realize that lack of adherence typically reflects the complexity of the
regimen rather than willful or manipulative behavior from the patient.”

Polypharmacy
46
Polypharmacy
§ Underappreciated barrier to OAC medication adherence § Potential risks of polypharmacy − Drug-drug interactions (e.g., gefitinib/anticoagulants; imatinib/rifampin; lapatinib/fentanyl) − Drug-food interactions (e.g., ibrutinib/grapefruit, Seville oranges; lapatinib/grapefruit) − Prescribing cascade − Unnecessary treatment change − Increased health care costs (physician visits; hospitalizations) § Why do interventions to improve adherence to OAC medication focus only on the OAC medication?
47
Pharmacists
Pharmacists are uniquely positioned to: § Evaluate a patient’s medications for potential drug-drug and drug-food interactions § Provide medication counseling and information about safe handling of medication § Provide medication reconciliation § Contact the prescribing physician § Assist in procuring the OAC medication in a timely fashion § Help patients obtain financial assistance so they can afford their medication
48
Why do we need this funding opportunity announcement?
§ Utilization − Little information is available on the adoption of newly approved targeted oral agents − Little information is available on off-label use of oral agents − Are targeted oral agents being prescribed appropriately? § Adherence − Strict adherence is critical to achieving an optimal clinical outcome − Suboptimal adherence may lead to relapse, side-effects, unnecessary treatment changes, increased use of health care resources § Health Care Delivery − Health care systems need to establish new roles, responsibilities, safety standards, patient education strategies for targeted oral therapies − Home-based treatment with targeted oral therapy requires new models of care coordination
49
Purpose
§ Assess and describe the current state of oral anticancer medication utilization, adherence, and delivery § Identify the structural, systemic, and psychosocial barriers to adherence § Develop models and strategies to improve safe and effective delivery of oral anticancer agents so that clinical outcomes are optimized
50
Utilization Challenges
§ Understand how OAC medications are being prescribed, used, and monitored − Disparities in access (e.g., rural and underserved populations, insurance) − Off-label use § Potential research questions: − What are the patient and provider characteristics associated with prescribing and use of OAC agents? − Do genetic testing requirements and health insurance coverage affect the utilization of OAC agents? − What are current trends in utilization of newly approved OAC therapies? − What are the patterns of off-label use of OAC medications?
51
Adherence Challenges
§ Understand how cognitive, affective, and motivational processes influence adherence behavior − Beliefs about the safety and effectiveness of a “pill” − Expectations about side effects, treatment outcome − Depression, anxiety § Understand the adherence needs of patients with cognitive, visual, physical, or health literacy limitations § Potential research questions: − How do patients perceive the risks associated with oral therapy, and how do these risk perceptions influence adherence? − Are there major differences in patterns of adherence depending on the duration or complexity
- f the treatment regimen?
− How do financial considerations (e.g., out-of-pocket costs) influence adherence?
52
Health Care Delivery Challenges
§ Understand how health care delivery systems are adapting to meet safety standards and the educational needs of patients and caregivers − Symptom management − Coordination of care § Potential research questions: − What system, health care team, provider, and patient-level factors are associated with the safe administration of oral agents? − How can pharmacy care models facilitate coordination of care for patients and health care teams? − What features of health care delivery systems lead to improved safety and adherence? − What models of care help to enhance symptom self-management?
53
Considerations
§ Studies may be observational/descriptive or include interventions;
- bservational studies should emphasize modifiable factors for future
interventions § Studies may focus on utilization, adherence, or health care delivery issues related to oral anticancer agents (no need to study everything) § Consult your Program Director if you have questions
54
Research Priorities
§ Cross-disciplinary collaborations (e.g., clinical pharmacists, research nurses, social workers, financial navigators) § Studies focused on newer targeted OAC agents § Primary data collection is encouraged

Shrinking the iceberg: Response Expectations
Criteria for consideration of treatment free remission (TKI cessation): the rules as noted by the NCCN
Age ≥18 years. Chronic phase CML. No prior history of accelerated or blast phase CML. On approved TKI therapy (imatinib, dasatinib, nilotinib, bosutinib, or ponatinib) for at least three years. Prior evidence of quantifiable BCR-ABL1 transcript. Stable molecular response (MR4; ≤0.01% IS) for ≥2 years, as documented on at least four tests, performed at least three months apart. No history of resistance to any TKI. Access to a reliable QPCR test with a sensitivity of detection of ≥4.5 logs that reports results on the IS and provides results within 2 weeks. Monthly molecular monitoring for the first six months following discontinuation, bimonthly during months 7–24, and quarterly thereafter (indefinitely) for patients who remain in MMR (MR3; ≤0.1% IS). Consultation with a CML Specialty Center to review the appropriateness for TKI discontinuation and potential risks and benefits of treatment discontinuation, including TKI withdrawal syndrome. Prompt resumption of TKI, with a monthly molecular monitoring for the first six months following resumption of TKI and every 3 months thereafter is recommended indefinitely for patients with a loss of
- MMR. For those who fail to achieve MMR after six months of TKI resumption, BCR-ABL1 kinase domain
mutation testing should be performed, and monthly molecular monitoring should be continued for another six months. Reporting of the following to a member of the NCCN CML panel is strongly encouraged:
- Any significant adverse event believed to be related to treatment discontinuation.
- Progression to accelerated or blast phase CML at any time.

Adherence in CML
What do we know
Adherence to therapy is a critical factor for achieving deep molecular response linked to treatment free remission
- MMR
- adherence to
imatinib therapy, RR=11.17 (p=0.001)
- CMR
- adherence to
imatinib therapy, RR=19.35 (p=0.004)

Long term adherence to imatinib
We’ve got issues: Doctor and Patient
- Challenging for busy oncologists to
be up to date on fine points of managing a relatively rare cancer such as CML (very diffuse CML care in US)
- TKI side effects not as dramatic as
those form traditional chemo and thus may be discounted
- Appointment/MD time short;
extenders (PAs, etc.) involved and nursing time limited/absent to counsel patients re: oral meds
- “Of course they are taking their
meds, it is cancer…”
- New paradigm in CML: chronic
maintenance therapy, ?indefinitely
- r at least x several years, unique
- Increasing attention needed to
- ptimize early tolerability and
monitor late effects for ‘endurance’ during chronic therapy
- Ongoing side effects may tempt
patients to secretly quit meds; not being taken seriously re: side effects may frustrate patients
- Financial burden, inadequate
insurance coverage, government costs, generics versus copies, etc.
- Medical system and society more
- riented to time-limited treatment,
not living life fully with cancer as a chronic disease: paradox of having cancer and still on treatment with no outward change in appearance
Why is toxicity management so important?
Adherence to therapy very likely to suffer in the case of poorly managed or under- managed side effects: ‘self-management’… Adherence to therapy, given the chronicity of therapy still necessary for patients with CML (advice ranges from 3+, 5+ to 8-10 yrs+) is one of the strongest predictors of

A: Awareness of cardiovascular disease signs and symptoms A: Aspirin (in select patients) A: Ankle-brachial index measurement at baseline and follow- up to document peripheral arterial disease B: Blood pressure control C: Cigarette/tobacco cessation C: Cholesterol (regular monitoring and treatment if indicated) D: Diabetes mellitus (regular monitoring, dose of radiation/chemotherapy, and treatment if indicated) D: Diet and weight management E: Exercise (echocardiogram)
= Recommended = As clinically indicated Imatinib Bosutinib Dasatinib Nilotinib Ponatinib Baseline Assessment Cardiovascular assessment Blood pressure check Fasting glucose Fasting lipid panel Echocardiogram * Electrocardiogram Ankle-brachial index 1-month follow up Cardiovascular assessment Blood pressure check 3- to 6-month follow-up Cardiovascular assessment Blood pressure check Fasting glucose Fasting lipid panel Echocardiogram * Electrocardiogram Ankle-brachial index *Patients treated with dasatinib should be considered for echocardiogram if cardiopulmonary symptoms are present.

Summary II
- Adherence has significant impact on response
- Landmark responses key to avoid progression (MMR)
- Landmark response key to consider TFR (MR4, CMR)
- Multiple liabilities:
- chronicity of therapy with oral therapy, uncertain end date
- Minimal disease symptoms, rapid/deep response (many “NED”)
- Low grade adverse events common
- More significant late effects under investigation, surveillance and risk assessment tools
needed
- Under-monitoring and lack of expertise are risks on the provider side
- Monitoring basic landmarks of response lacking
- Switch of therapy common
Take-aways
- CML has opened the door to ‘cure’ with oral, low risk therapy
(prior to imatinib, hormonal therapy for breast cancer and trastuzumab were only ‘targeted’ therapies)
- All the challenges of chronic oral therapy exist and are
magnified by impact on response and outcome
- ‘Good problems: many drug choices; rapid response; lack or
reinforcement of disease presence; common to be managing disease detected at minute levels or ‘NED’
- Uncertainty about length of therapy and treatment free
remission leaves the ‘end game’ nebulous…
