NEW ORLEANS – In a survey of pediatric hematologists, quality of life was the most frequently cited reason for starting second-line therapy in children with immune thrombocytopenia.
Quality of life (QOL) was an indication for second-line treatment in nearly three-quarters of patients studied, and it ranked among the top three indications – along with bleeding frequency and bleeding severity – for treatment in more than half of patients.
Kristin A. Shimano, MD, of the department of pediatrics at the University of California, San Francisco, presented these results at the annual meeting of the American Society of Pediatric Hematology/Oncology.
Dr. Shimano and colleagues surveyed hematologists treating children in the ICON1 study (Am J Hematol. 2019 Apr 3. doi: 10.1002/ajh.25479).
The study enrolled 120 children receiving second-line immune thrombocytopenia (ITP) treatment at 21 centers. The median age at enrollment was 11.7 years (range, 1.2-17.8 years). About half of patients (53%) had chronic ITP, 31% had persistent ITP, and 16% had newly diagnosed ITP. The median number of prior treatments was three (range, zero to eight).
At study entry, the hematologists were asked to provide reasons that patients required second-line treatment. The list of 12 possible reasons included patient or parent QOL; bleeding severity; bleeding frequency; severity of thrombocytopenia; chronicity of ITP; high baseline activity level; involvement in sports; patient age; distance from medical center; and parent, patient, or physician anxiety. The hematologists were asked to choose all reasons that applied and to rank the top three reasons.
QOL was chosen as a reason to treat in 73% of patients (n = 88). QOL was among the top three reasons in 57% of patients (n = 68) and was the most important reason in 27% of patients (n = 32).
The severity and frequency of bleeding were ranked among the top three indications as well. Bleeding severity was a top indication in 29% of cases (n = 35), and bleeding frequency was a top indication in 40% of cases (n = 48).
Reasons for starting second-line treatment varied depending on patients’ phase of disease.
Bleeding severity was significantly more likely to be an indication for treatment among patients who had newly diagnosed or persistent ITP (69%), rather than chronic ITP (31%; P = .0025). Bleeding frequency was also significantly more likely to be an indication among patients with newly diagnosed or persistent ITP (63% vs. 37%; P = .0054).
Conversely, QOL was significantly more likely to be an indication for patients with chronic ITP (65%) rather than newly diagnosed or persistent ITP (35%, P = .0056). Sports participation was a more likely indication among patients with chronic ITP as well (75% vs. 26%, P = .017).
Indications for treatment also varied according to baseline platelet counts. For example, QOL was an indication for treatment in 42% of patients with baseline platelet counts less than 10 x 109/L and 78% of patients with platelet counts of 20 x 109/L or greater. So the higher the baseline platelet count, the more likely QOL was an indication for treatment (P = .006).
On the other hand, the importance hematologists placed on QOL did not appear to correlate with actual health-related QOL as assessed by the Kids ITP Tool. There was no difference reported in baseline health-related QOL, according to the tool, in children for whom QOL was ranked versus unranked by hematologists.
This finding suggests physicians may not be adequately assessing the impact of ITP on QOL, Dr. Shimano said.
“Better clinical measures of the impact of ITP on patient quality of life are needed to assess both need for treatment and treatment response,” she said. “Understanding the effects of individual second-line treatments on quality of life is critical for this patient population in order to best tailor therapy for each patient.”
Dr. Shimano reported involvement in an investigator-initiated trial for eltrombopag in children with ITP. The study, which has not yet opened, is funded by Novartis.
