    PURPOSE: Given that the prognosis of recurrent malignant glioma (MG) remains poor, improving quality of life (QoL) through symptom management is important. Meta-analyses establishing antiemetic guidelines have demonstrated the superiority of palonosetron (PAL) over older 5-hydroxytryptamine 3-receptor antagonists in chemotherapy-induced nausea and vomiting (CINV) prevention, but excluded patients with gliomas. Irinotecan plus bevacizumab is a treatment frequently used in MG, but is associated with low (55%) CINV complete response (CR; no emesis or use of rescue antiemetic) with commonly prescribed ondansetron. A single-arm Phase II trial was conducted in MG patients to determine the efficacy of intravenous PAL (0.25 mg) and dexamethasone (DEX; 10 mg) received in conjunction with biweekly irinotecan-bevacizumab treatment. The primary end point was the proportion of subjects achieving acute CINV CR (no emesis or antiemetic ≤24 hours postchemotherapy). Secondary end points included delayed CINV CR (days 2-5), overall CINV CR (days 1-5), and QoL, fatigue, and toxicity. MATERIALS AND METHODS: A two-stage design of 160 patients was planned to differentiate between CINV CR of 55% and 65% after each dose of PAL-DEX. Validated surveys assessed fatigue and QoL. RESULTS: A total of 63 patients were enrolled, after which enrollment was terminated due to slow accrual; 52 patients were evaluable for the primary outcome of acute CINV CR. Following PAL-DEX dose administrations 1-3, acute CINV CR rates were 62%, 68%, and 70%; delayed CINV CR rates were 62%, 66%, and 70%, and overall CINV CR rates were 47%, 57%, and 62%, respectively. Compared to baseline, there was a clinically meaningful increase in fatigue during acute and overall phases, but not in the delayed phase. There were no grade ≥3 PAL-DEX treatment-related toxicities. CONCLUSION: Data suggest that PAL-DEX is effective in preventing CINV in MG patients, which ultimately maintains the QoL of patients with glioma.

    INNV-20. RADIOGRAPHIC RESPONSE AND SEIZURE CONTROL IN IDH1 MUTANT GLIOMA PATIENTS USING IVOSIDENIB
    (Neuro-Oncology, 2021-11-12) Peters, Katherine; Patel, Mallika; Alford, Candice; Chavez, Gerardo; Kim, Jung-Young; Durling, Jennifer; Novack, Tracy; Batich, Kristen; Shoaf, Madison; Hanzlik, Emily; Affronti, Mary; Johnson, Margaret; Landi, Daniel; Khasraw, Mustafa; Desjardins, Annick; Friedman, Henry; Ashley, David M
    Abstract Isocitrate dehydrogenase 1 (IDH1) is commonly mutated in grade II-III gliomas, and the mutant enzyme leads to the production of the oncometabolite 2-hydroxyglutarate (2-HG). 2-HG is responsible for the gliomagenesis associated with these tumors and the promotion of seizures via glutamate receptors. Ivosidenib, a small molecule oral mIDH1 inhibitor, has shown promise in clinical trials to treat IDH1 mutant gliomas, and providers can utilize this agent in IDH1 mutant glioma patients. We evaluated our IDH1 mutant glioma patients treated off-label with ivosidenib and described the radiographic response and seizure control in this cohort when ivosidenib was initiated between October 2020 to February 2021. Radiographic response was determined using RANO criteria, and seizure control was determined by comparing seizures per month before and after initiation of ivosidenib. All patients represented received single-agent ivosidenib dosed at 500 mg orally once a day. One patient required a dose reduction to 250 mg orally once a day because of drug-induced diarrhea. In our cohort of six patients, patient age range was 31 to 74 years with four female patients and two male patients. Diagnoses represented were astrocytoma, IDH1 mutant (n=3) oligodendroglioma (WHO), IDH1 mutant, 1p19q co-deleted (n=2), and anaplastic astrocytoma IDH1 mutant (n=1). Three patients experienced a reduction of seizure frequency, two patients did not have seizures before or after therapy, and one patient remained with the same level of seizures (1 seizure/month). Radiographic responses recorded included three patients with stable disease, two patients with minor responses, and one patient with a partial response. Treatment with ivosidenib is ongoing for this cohort of mIDH1 glioma patients. Updated information on prolonged disease control and seizure control in this cohort of IDH1 mutant glioma patients will be presented. Therapeutics, such as ivosidenib, can lead to improved seizure control and radiographic outcomes in IDH1 mutant glioma patients.

    QOLP-10. A LONGITUDINAL OBSERVATIONAL STUDY OF EXERCISE BEHAVIOR IN GLIOBLASTOMA PATIENTS TREATED WITH TUMOR-TREATING FIELDS
    (Neuro-Oncology, 2021-11-12) Peters, Katherine; Affronti, Mary; Kim, Jung-Young; Patel, Mallika; Johnson, Margaret; Bartlett, David; Cort, Nicole; Lipp, Eric; Iden, Deborah; Broadwater, Gloria; Herndon, James; Landi, Daniel; Khasraw, Mustafa; Desjardins, Annick; Friedman, Henry; Ashley, David M
    Abstract Glioblastoma (GBM) patients can use tumor-treating fields (TTFs) with adjuvant temozolomide (TMZ) to treat their disease. TTFs involve wearing transfixed transducers to the shaved scalp, and the transducers are wired to a battery pack that is either fixed or carried (weighing 2.7 pounds). EF-14 clinical trial did evaluate health-related quality of life with standardized patient-report outcome measures but did not measure exercise behavior. We sought to evaluate the exercise behavior of GBM patients using TTFs. We consented GBM patients who intended to use TTFs with adjuvant TMZ after completion of chemoradiation. After informed consent and before starting TTFs, patients completed a self-administered questionnaire, Godin Leisure-Time Exercise Questionnaire, to assess exercise behavior/physical function. To calculate our primary outcome of total exercise behavior, the frequency of exercise sessions per week within each intensity category was multiplied by the average reported duration, weighted by an estimate of the MET, summed across all intensities, and expressed as average MET-hr/wk. Prior work has defined that physical function can be compared as < 9 MET-h/wk vs. ≥ 9 MET-h/wk. We evaluated at baseline and up to 24-week exercise behavior in patients with TTFs vs. historical controls not using TTFs. We enrolled 19 total GBM patients, with 14 proceeding to use TTFs. Of the 14 patients on TTFs, seven patients (50%) completed ≥ 9 MET-h/wk of exercise, and this level was maintained 8, 16, and 24 weeks after starting TTFs. Six months after the completion of chemoradiation, mean MET-h/wk was decreased in the TTFs group (n=6) (10.71 sd=7.06) vs. historical controls (n=38) (27.35 sd=46.94). TTFs did not interfere with exercise behavior in our GBM cohort, but when compared to GBM patients not utilizing TTFs, there could be a long-term impact on exercise behavior. More research is needed to evaluate exercise behavior in GBM patients using TTFs.

    QOLP-28. COMPARING KNOWLEDGE OF AND BELIEFS ABOUT PALLIATIVE CARE AMONG NEURO-ONCOLOGY PATIENTS, CAREGIVERS, PROVIDERS AND A NATIONALLY-REPRESENTATIVE U.S. SAMPLE
    (Neuro-Oncology, 2021-11-12) Johnson, Margaret; Khasraw, Mustafa; Kim, Jung-Young; Cort, Nicole; Herndon, James; Ramirez, Luis; Lipp, Eric; Landi, Daniel; Desjardins, Annick; Friedman, Henry; Ashley, David M; Affronti, Mary; Casarett, David J; Peters, Katherine B
    Abstract INTRODUCTION There is increasing recognition that palliative care (PC) can benefit patients with advanced cancers. However, early referral to PC is not yet a reality for patients diagnosed with a primary brain tumor. We hypothesize that lack of knowledge and/or misperceptions regarding PC by patients, caregivers, or their providers remain barriers. METHODS This is an IRB-exempt, one-time QR-accessible REDcap questionnaire administered to patients, caregivers, and providers at the Preston Robert Tisch Brain Tumor Center between September 2020 and May 2021. We administered 9 questions regarding knowledge and beliefs about PC from the Health Information National Trends Survey 5, Cycle 2: results of this nationally representative U.S. sample are publicly available and used for comparison. RESULTS We had 141 survey respondents: 25 providers, 59 patients, and 57 caregivers. The median patient and caregiver ages were 49 (21-74) and 50 years (24-73), respectively. Caregivers were more likely female (55.2 %) and identified as a spouse or domestic partner (58.2%). Providers, were equally distributed by years of experience. Compared to patients and caregivers, providers reported more baseline knowledge of PC (p< 0.0001, p< 0.0001) and better understood the role of PC in pain/symptom management (p=0.0038, p=0.0087) and social/emotional support (p=0.0044, p=0.0279). Interestingly, most providers (76.0%) disagreed with the statement “the goal of palliative care is to give patients more time at the end of life.” Compared to a general U.S. sample (n=1,162) our patients (n=39) were better informed in only 2 of 9 questions. Whereas, caregivers (n=48) were better informed in 6 of 9 questions. CONCLUSION Neuro-oncology providers were knowledgeable, but a minor gap in understanding the goal of PC was identified. Caregivers were overall more knowledgeable than patients. However, Neuro-oncology patients, had similar knowledge and beliefs compared to a nationally representative sample. PC interventions should prioritize filling knowledge gaps for Neuro-oncology patients.
