Treatment preferences of adults and adolescents with alopecia areata: A discrete choice experiment.

PRODUCTS with janus kinase (JAK) inhibition have been shown to promote hair regrowth in patients with alopecia areata (AA). To guide drug-approval and treatment decisions, it is important to understand patients' willingness to accept the potential risks of JAK inhibition in exchange for potential benefits. We quantified the treatment preferences of adult (≥18 years) and adolescent patients (12-17 years) with AA in the US and Europe to determine the trade-offs they are willing to make between benefits and risks. Preferences for oral AA treatment attributes were elicited using a discrete choice experiment consisting of 12 tasks in which patients chose between two hypothetical treatment alternatives and no treatment. Benefits included the probability of 80%-100% scalp hair regrowth (Severity of Alopecia Tool score ≤ 20) and achieving moderate-to-normal eyebrow and eyelash hair. Treatment-related risks included 3-year probabilities of serious infection, cancer, and blood clots. Preference estimates were used to calculate the maximum level of each risk that patients were willing to accept for increases in treatment benefits. The most important attribute to both adults (n = 201) and adolescents (n = 120) was a 50% probability of achieving hair regrowth on most or all the scalp; however, adolescents placed greater relative importance on this attribute than did adults. Adults were averse to the risks of serious infection, cancer, and blood clots, whereas adolescents were averse to the risk of cancer. For a 20% increase in the probability of 80%-100% scalp hair regrowth, adults were willing to accept a mean (95% confidence interval) 3-year risk of serious infection, cancer, and blood clots of 7.4% (5.5-9.3), 2.5% (1.9-3.1), and 9.3% (6.4-12.2). Adolescents were willing to accept a 3-year risk of cancer of 3.3% (2.4-4.2). Patients with AA in the US and Europe are willing to accept substantial risks to obtain an effective treatment.

Regulatory benefit-risk assessment of oncology drugs: A systematic review of FDA and EMA approvals.

The European Medicines Agency (EMA) and FDA have policy goals of strengthening benefit-risk (B-R) capabilities; but how this has been translating into regulatory practice is unclear. A systematic review of oncology drug approvals between 2015 and 2020 was conducted with approvals identified through review of FDA and EMA annual reports, with extraction of information on submission, clinical program and B-R assessment from publicly available review documents. Data were extracted from 236 reviews (EMA: 66 new submissions, 100 label extensions; FDA: 70 new submissions). The standard of evidence for B-R assessments seems to have diversified over time; yet, despite policy targets to extend their use, these assessments rarely include patient experience or real-world data.

Current Health State Affected Patient Preferences More Than Disease Status: A Discrete Choice Experiment in Multiple Myeloma.

OBJECTIVES: To examine how disease status and current health state influence treatment preferences of patients with multiple myeloma (MM). METHODS: Participants with MM from France, Germany, and the United Kingdom completed a web-based survey that included a discrete choice experiment (DCE) and EQ-5D assessment. The DCE elicited preferences for 8 attributes: increased life expectancy, increased time to relapse, pain, fatigue, risk of infection, administration (route and duration), frequency of administration, and monitoring. Multinomial logit models were used to analyze DCE preference data and to calculate life expectancy trade-offs. RESULTS: Three hundred participants with MM (newly diagnosed, transplant eligible, n = 108; newly diagnosed, transplant ineligible, n = 105; relapsed-refractory, n = 87) completed the survey. The most valued attributes were pain, fatigue, and increased life expectancy. Participants would want an additional 2.7 years of life expectancy (95% confidence interval [CI] 2.4-3.1 years) to tolerate extreme pain and an additional 2.0 years of life expectancy (95% CI 1.6-2.3 years) to tolerate constant fatigue. Participants in a better health state (third EQ-5D score quartile [0.897]) required less additional life expectancy than participants with a worse health state (first EQ-5D score quartile [0.662]) to tolerate extreme pain (2.3 years [95% CI 1.9-2.6 years] vs 3.0 years [95% CI 2.6-3.4 years]; P = .007). There was little difference in treatment preferences between newly diagnosed and relapsed-refractory patients for pain, fatigue, and increased life expectancy. CONCLUSIONS: Current health state influenced treatment preferences of patients with MM more than disease status and should be considered when making treatment decisions.

Patient Preferences of Low-Dose Aspirin for Cardiovascular Disease and Colorectal Cancer Prevention in Italy: A Latent Class Analysis.

BACKGROUND: Patients taking low-dose aspirin to prevent cardiovascular disease (CVD) may also benefit from a reduced risk of colorectal cancer (CRC). OBJECTIVE: The aim was to examine the preferences of people eligible for preventive treatment with low-dose aspirin and the trade-offs they are willing to make between CVD prevention, CRC prevention, and treatment risks. METHODS: A cross-sectional study using a discrete choice experiment (DCE) survey was conducted in Italy in 2019 to elicit preferences for three benefit attributes (prevention of ischemic stroke, myocardial infarction, and CRC) and four risk attributes (intracranial and gastrointestinal bleeding, peptic ulcer, and severe allergic reaction) associated with use of low-dose aspirin. Latent class logit models were used to evaluate variation in treatment preferences. RESULTS: The DCE survey was completed by 1005 participants eligible for use of low-dose aspirin. A four-class model had the best fit for the primary CVD prevention group (n = 491), and a three-class model had the best fit for the secondary CVD prevention group (n = 514). For the primary CVD prevention group, where classes differed on age, education level, type 2 diabetes, exercise, and low-dose aspirin use, the most important attributes were intracranial bleeding (two classes), myocardial infarction (one class), and CRC (one class). For the secondary CVD prevention group, where classes differed on various comorbidities, self-reported health, exercise, and CVD medication use, the most important attributes were intracranial bleeding (two classes), myocardial infarction (one class), and gastrointestinal bleeding (one class). CONCLUSION: Patient preferences for the benefits and risks of low-dose aspirin differ significantly among people eligible for treatment as primary or secondary CVD prevention.

Patient Perceptions Regarding Multiple Myeloma and Its Treatment: Qualitative Evidence from Interviews with Patients in the United Kingdom, France, and Germany.

BACKGROUND: The current standard of care for multiple myeloma requires several regimens of treatment, with patients experiencing high symptom burden and side effects, which negatively impact health-related quality of life (HRQoL). Thus, it is crucial to understand patient perceptions of multiple myeloma and how patients value different treatment options. OBJECTIVE: The purpose of this study was to conduct an exploratory investigation into concepts that could form attributes that influence treatment choices for patients with multiple myeloma and to identify trade-offs that patients are willing to make between treatment attributes. METHODS: In total, 30 patients with newly diagnosed or relapsed/refractory multiple myeloma from the UK, France, and Germany participated in semistructured interviews talking about their disease experience and symptoms, treatment benefits, treatment burden, perceived side effects, and benefit/risk trade-offs in treatment. The interview audio recordings were transcribed and analyzed using content analysis to identify treatment and disease aspects relevant to patients. RESULTS: Symptoms of fatigue and bone pain and treatment side effects of peripheral neuropathy, diarrhea, and constipation were cited by patients as the most disruptive to their HRQoL. Treatment duration was reported most frequently as a major treatment burden, and patients emphasized the importance of increased life expectancy as a treatment benefit. All patients showed good understanding of benefit/risk trade-offs in treatment, and some patients expressed a preference for more convenient modes of treatment administration. CONCLUSIONS: Qualitative interviews identified key aspects of multiple myeloma treatment that are most important to patients. These findings will inform a wider patient-preferences study, which could improve treatment choice and HRQoL for patients with multiple myeloma.
