Combination of Optune™ with Standard of Care Chemotherapy, Temozolomide, Delayed Decline in Several Health-Related Quality of Life Scales Compared to Temozolomide Alone for Newly Diagnosed Glioblastoma Patients
Addition of Optune to temozolomide did not negatively impact quality of life for newly diagnosed glioblastoma patients except for causing itchy skin
ST. HELIER, Jersey–(BUSINESS WIRE)–
“Some physicians and patients have expressed concerns regarding the possible negative impact of Optune on patient quality of life” said
Patients completed two validated health-related quality of life questionnaires (EORTC QLQ-C30 and BN20) at the beginning of the trial, and every three months thereafter. Health-related quality of life over time was assessed for nine preselected scales: global health, physical, cognitive, role, social and emotional functioning, itchy skin, pain and weakness of legs. The results were as follows:
- More patients treated with the combination of Optune and temozolomide reported stable or improved scores on: global health status (53 percent versus 38 percent, p=.001), pain (57 percent versus 36 percent, p<.0001), physical functioning (54 percent versus 38 percent, p=.001) and leg weakness (59 percent versus 42 percent, p=.001) when compared to patients treated with temozolomide alone.
- Deterioration-free survival (the time until quality of life declined by more than 10 points or disease progression) was longer (p<.01) for patients treated with the combination of Optune and temozolomide versus patients treated with temozolomide alone for: global health (4.8 versus 3.3 months), physical (5.1 versus 3.7 months) and emotional functioning (5.3 versus 3.9 months), pain (5.6 versus 3.6 months) and leg weakness (5.6 versus 3.9 months).
- Time to deterioration (the time until quality of life declined by more than 10 points, excluding disease progression) did not significantly differ between treatment arms, except for itchy skin (8.2 months for patients treated with Optune plus temozolomide versus 14.4 months for patients treated with temozolomide alone, p<.001), and pain (13.4 months for patients treated with Optune plus temozolomide versus 12.1 months for patients treated with temozolomide alone, p<.001).
- Health-related quality of life over time did not significantly differ between treatment arms except for itchy skin, which was worse with Optune plus temozolomide versus temozolomide alone, at three, six and nine months (p=.0004).
“This data further cements our belief that Optune plus temozolomide should be offered as an essential combination therapy to every newly diagnosed patient with glioblastoma,” said
