Huntington's Disease Community Perspectives on Desired Characteristics of Disease Modifying Therapies.

ABSTRACT:

Background

Promising disease modifying therapies for Huntington's disease are now entering pivotal trials, raising questions of what patients and families consider successful outcomes. Consistent with an ongoing movement to incorporate patient preferences into the development of new therapies, we conducted a pilot study to assess Huntington's disease community views on emerging DMTs to assist in planning large-scale studies of patient preferences.

Methods

Semi-structured interviews were conducted with members of the Huntington's community (manifest disease, at-risk, and family/caregivers). Participants were asked which symptoms they believed should be targeted with novel treatments, as well as potential benefits and tradeoffs of delaying symptom onset versus prolonging late-stage disease.

Results

Participants (N = 14) emphasized the need for treatments improving cognitive and/or behavioral symptoms. Many wanted treatments that delayed symptom onset up to 5-10 years, though some considered shorter delays acceptable due to potential value in advancing research to help future generations. Concern regarding potential for prolonging later-stage disease was variable, with some participants uncertain if they would want a treatment that delayed onset but prolonged later-stage disease. Others stated that any delay in onset would be desirable, regardless of potential prolongation of later stage disease.

Discussion

This study demonstrates a breadth of opinions among the Huntington's disease community surrounding both the benefits and complex tradeoffs that might occur with disease modifying treatments. These preliminary findings will inform future large-scale studies of attitudes toward disease modifying treatments, which may ultimately guide the design and outcome measure selection for clinical trials.

Highlights

In-depth interviews with the Huntington's disease community were used to explore patient and family preferences regarding potential disease modifying therapies. Many wanted symptom delay of 5-10 years, though some considered shorter delays acceptable for altruistic reasons. Opinions on trade-offs varied, suggesting larger preference studies are needed to inform trial design.

Project description:Sickle cell disease (SCD) is an inherited blood disorder that primarily affects African-American and other ethnic minority populations. There are three available disease-modifying therapies for sickle cell disease: hydroxyurea (HU), bone marrow transplantation (BMT), and chronic blood transfusion (CBT). Since these treatments vary in their therapeutic intent, efficacy in preventing progression of the disease, short and long-term adverse effects, costs and patient burden, the decision-making process regarding these therapies is complicated for both the patient and healthcare provider. While previous research has focused on the patient perspective of treatment-related decision making, there is a paucity of research investigating the physician perspective of treatment-related decision making. We conducted a qualitative study with physicians who were experts in the field of SCD. Interviews focused on physician perceptions of patient decisional needs as well as physicians' approach to decision making regarding disease-modifying therapies in SCD. Thirty-six physician interviews were analyzed, with a focus on their perspectives regarding available treatment options and on how they approach decision making with patients. We identified two narrative approaches. The Collaborative approach (CA) was characterized by emphasizing the need to discuss all possible treatment options to ensure that the patient and/or family was equipped to make an informed decision. The Proponent approach (PA) was characterized by strongly advocating a pre-determined treatment plan and providing patients/families with information, with the objective of convincing them to accept the treatment. An interplay of patient-related and disease-related factors, decision type and physician-related factors, as well as institutional frameworks, influenced physician perspectives on treatment options and decision making regarding these therapies. These findings point to the potential value of developing systems to foster patient engagement as a way of facilitating shared decision making.

Project description:Sickle cell disease afflicts millions of people worldwide and approximately 100,000 Americans. Complications are myriad and arise as a result of complex pathological pathways 'downstream' to a point mutation in DNA, and include red blood cell membrane damage, inflammation, chronic hemolytic anemia with episodic vaso-occlusion, ischemia and pain, and ultimately risk of cumulative organ damage with reduced lifespan of affected individuals. The National Heart, Lung, and Blood Institute's 2014 evidence-based guideline for sickle cell disease management states that additional research is needed before investigational curative therapies will be widely available to most patients with sickle cell disease. To date, sickle cell disease has been cured by hematopoietic stem cell transplantation in approximately 1,000 people, most of whom were children, and significantly ameliorated by gene therapy in a handful of subjects who have only limited follow-up thus far. During a timespan in which over 20 agents were approved for the treatment of cystic fibrosis by the Food and Drug Administration, similar approval was granted for only two drugs for sickle cell disease (hydroxyurea and L-glutamine) despite the higher prevalence of sickle cell disease. This trajectory appears to be changing, as the lack of multimodal agent therapy in sickle cell disease has spurred engagement among many in academia and industry who, in the last decade, have developed new drugs poised to prevent complications and alleviate suffering. Identified therapeutic strategies include fetal hemoglobin induction, inhibition of intracellular HbS polymerization, inhibition of oxidant stress and inflammation, and perturbation of the activation of the endothelium and other blood components (e.g. platelets, white blood cells, coagulation proteins) involved in the pathophysiology of sickle cell disease. In this article, we present a crash-course review of disease-modifying approaches (minus hematopoietic stem cell transplant and gene therapy) for patients with sickle cell disease currently, or recently, tested in clinical trials in the era following approval of hydroxyurea.
