STAINES-UPON-THAMES, United Kingdom, March 4, 2019 /PRNewswire/ -- Mallinckrodt plc (NYSE: MNK), a leading global specialty pharmaceutical company, today announced data from a retrospective cohort analysis that assessed the potential resource and cost impact of continuation of systemic treatment (ST) on healthcare utilization among U.S. patients with cutaneous T-cell lymphoma (CTCL). The analysis included 1,081 patients with CTCL with continuous enrollment three months before and six months after initiation of ST.
Results of the study were published online in an eposter on Friday, March 1, 2019, and were presented on Saturday, March 2 at 2:00 p.m. EST in an oral discussion at the 2019 American Academy of Dermatology Annual Meeting in Washington, D.C.
The intended audience of this study is population-based decision makers with knowledge and expertise in the area of health care economic analysis and its limitations.
"This is one of the first studies of its kind to look at the potential resource and cost impact of continuation of systemic therapy for CTCL and demonstrates our commitment to provide data to support informed decision-making," said Tunde Otulana, M.D., Senior Vice President and Chief Medical Officer at Mallinckrodt. "It is an important addition to the body of knowledge on CTCL, as examining resource utilization and costs can lead to improvements in healthcare overall."
- A retrospective cohort analysis examined health insurance claims databases from 2010 to 2015 to assess the impact of continuation of ST on healthcare utilization in U.S. patients with CTCL.
- Data were examined for 1,081 patients with CTCL with continuous enrollment three months before and six months after initiation of ST.
- ST continuation was defined as persistence to treatment for ≥180 days without a gap of 45 days or more.
- Logistic regression was performed to assess factors associated with ST continuation.
- On average, ST treatment duration was 17.2 months (median 11.7 months).
- Overall, 663 patients were continuers as defined; 418 were discontinuers (gap in ST treatment for 45 days or more in a ≥180 days period).
- Continuers had 0.04 monthly emergency room (ER) visits and discontinuers had 0.10 monthly ER visits (p=0.002).
- Continuers had 0.02 monthly hospitalizations and discontinuers had 0.06 monthly hospitalizations (p<0.001).
- Continuers had 0.17 monthly inpatients days and discontinuers had 0.57 monthly inpatient days (p<0.001).
- Continuers had monthly ER costs of $61.33 and discontinuers had monthly ER costs of $169.17 (p=0.02).
The findings should be carefully interpreted:
- There is no recommended treatment duration for some STs.
- The six-month time frame selected for evaluation in this analysis is not based on recommended treatment duration for all STs in the study.
- The reasons why patients discontinued treatment are not known and cannot be evaluated.
The study was supported by Mallinckrodt.
"CTCL is diagnosed in approximately 3,000 new patients in the U.S. each year and treatments include a number of available systemic therapies for advanced disease," said Larisa Geskin, M.D., Associate Professor of Dermatology at Columbia University Medical Center and Director of the Comprehensive Skin Cancer Center at the Division of Cutaneous Oncology in the Department of Dermatology. "While there is no recommended duration of use for some systemic therapies, these data provide important insights on the potential impact of treatment discontinuation on healthcare costs and utilization."
Cutaneous T-cell lymphoma (CTCL) is an umbrella term for a group of non-Hodgkin lymphomas involving T lymphocytes that localize in the skin. It is a relatively rare cancer, with 2,500 to 3,000 new cases per year in the United States.1 The age of onset of the condition is typically greater than 50 years, with the incidence rising significantly in the later decades of life.2
