Racial disparities in treatment use for multiple myeloma.

ABSTRACT:

Background

Recent treatment advances have greatly improved the prognosis of patients with multiple myeloma. However, some of these newer, more effective treatments are intensive and expensive and their use remains low, particularly among black patients.

Methods

In the current study, the authors reviewed the use patterns of stem cell transplantation and bortezomib using the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database.

Results

After controlling for overall health and potential access barriers, black patients were found to be 37% (P<.0001) less likely to undergo stem cell transplantation, and 21% (P<.0001) less likely to be treated with bortezomib. Moreover, the authors found that the underuse of these treatments was associated with a 12% increase in the hazard ratio for death among black patients (P = 0.0007).

Conclusions

Eliminating health disparities, a current focus of US public policy, is highly complex, as illustrated by the results of the current study. In patients with multiple myeloma, treatment disparities are not completely explained by potential access barriers. Additional factors, such as structural barriers in the health care system and individual decision making among black and white patients, must be explored to fully explain the disparity.

Project description:ImportanceThe use of chimeric antigen receptor-T cell (CAR-T) therapy and bispecific antibodies in multiple myeloma is expanding, with encouraging early results. It is unknown if the current geographic distribution of CAR-T therapy and bispecific antibodies in multiple myeloma allows access for patients in need, especially for Black populations, which have a higher incidence of multiple myeloma.ObjectiveTo investigate if the current geographic distribution of CAR-T cell therapy and bispecific antibodies for multiple myeloma allows equitable access for Black patients with multiple myeloma.Design, setting, and participantsThis cross-sectional study of data from CAR-T therapy and bispecific antibodies multiple myeloma clinical trials for all available studies listed in ClinicalTrials.gov until January 31, 2022. Only studies with 1 or more open sites in the US were analyzed. Data were analyzed February 2022.ResultsA total of 162 clinical trials were found, and 69 analyzed-7896 participants were either enrolled or expected to enroll, with 4386 participants (55.5%) enrolled or to be enrolled in CAR-T therapies clinical trials. The vast majority of clinical trials (66 [96%]) were sponsored by industry, and there were 140 clinical trials sites. The mean number of sites per trial was 8.1 (7.8 for CAR-T trials [range, 1-30 trials] vs 8.7 for bispecific antibodies [range, 1-26 trials]). Only 35.9% of Black patients lived in a county with an open trial. For the 10 states with the highest proportion of Black residents (ranging from 18.6% to 41.4%), 6 of those states (60%) had no (3 states) or less than 3 clinical trial openings (3 states) for either a CAR-T or bispecific antibody study.Conclusions and relevanceIn this cross-sectional study, we found that the geographic distribution of clinical trials for CAR-T and bispecific antibodies may contribute to disparities in access to the most advanced clinical trials for new multiple myeloma therapies. Since most of the ongoing trials were sponsored by industry, regulating the distribution of clinical trial sites may reduce these inequities.

Project description:BackgroundHypertension adversely impacts the multiple sclerosis (MS) disease course and is more common among Black Americans. Disparities in care due to structural racism may lead to suboptimal hypertension detection and control in Black American MS patients.ObjectivesTo determine if uncontrolled hypertension is more common in Black or White Americans with MS and whether race impacts the likelihood of receiving anti-hypertensive treatment.MethodsA retrospective cohort study was conducted using longitudinal data from American participants in the Multiple Sclerosis Partners Advancing Technology and Health Solutions (MS PATHS) multi-institutional registry. Data was collected from 7 sites in the United States between May 2015 and November 2020. Patients with uncontrolled hypertension, defined as ≥2 blood pressure measurements ≥140/90 mmHg, were identified in the dataset. Racial differences in uncontrolled hypertension and odds of anti-hypertensive treatment were evaluated using logistic regression. Predictors of anti-hypertensive treatment in those with uncontrolled hypertension were determined by race.ResultsThe analysis included 10,673 MS patients, of whom 1,442 (13.5%) were Black Americans. Despite a lower mean age (45.7 vs. 49.2 years), Black Americans had a 31% increased odds of uncontrolled hypertension compared to White Americans. After adjustment for relevant covariates, mean systolic blood pressure was 1.84 mmHg (95% confidence interval=1.07-2.61) higher in Black Americans than White Americans, and mean diastolic blood pressure was 1.28 mmHg (95% confidence interval=0.74-1.82) higher. Black Americans were also more likely to be on anti-hypertensive therapy (OR=1.68, 95% confidence interval=1.30-2.18) and were exposed to an adjusted average of 0.61 (95% confidence interval=0.45-0.78) more anti-hypertensive treatments than White Americans (p<0.001). Age, comorbid diabetes mellitus, and comorbid hyperlipidemia were positively associated with use of anti-hypertensive treatments in all patients with uncontrolled hypertension.ConclusionBlack American MS patients have significantly increased odds of uncontrolled hypertension, but also higher odds of receiving anti-hypertensive treatment.
