12500 Background: Endothelial proliferation has been recognized as a marker of high grade or aggressive glioma in several grading classifications and it has been demonstrated that the degree of microvascularity as assessed by the endothelial cell/capillary density correlates well with the biologic aggressiveness of these tumors. These features suggest that high grade gliomas are a suitable target for angiogenesis inhibiting therapies. Bevacizumab (B) is a humanized IgG1 monoclonal antibody to VEGF that has been shown to have activity in malignant gliomas when combined with irinotecan (CPT-11), a topoisomerase 1 inhibitor. Methods: We report a case series of 10 patients with recurrent, heavily pre-treated malignant glioma who were treated with the combination of B and CPT-11. Nine patients had WHO grade 4 tumors while one had a grade 3 lesion. All patients had failed standard therapy with primary resection followed by adjuvant chemotherapy and radiation. Most had also failed additional resection, chemotherapy and radiation after their initial relapse. The mean number of failed therapies in addition to adjuvant therapy prior to starting B and CPT-11 was 3 (range 1–6) and the median ECOG performance status was 2 (range 1–3). Nine patients were started on B at a dose of 5 mg/kg every 2 weeks and were given CPT-11 at a dose of 125 mg/m2 every week for 3 weeks with 1 week off. The tenth patient received B at a dose of 10 mg/kg but with CPT-11 at 125 mg/m2 every 2 weeks. Results: This regimen was well tolerated with no CNS hemorrhages or >grade 1 bleeding. One patient had treatment held for repair of an anal fissure but then had it restarted. One patient had a DVT while on therapy. The objective response rate was 80% (8 PR and 2 SD).The median progression- free interval on treatment is 25 weeks with 5 patients still having a response at the time of this report. In patients with progressive disease, the median time to progression is 25 weeks. The median overall survival has not been reached, and exceeds 6 months. There has been one death due to disease progression. Conclusion: The combination of B and CPT-11 is safe and has excellent activity even in this relapsed, heavily pre-treated population of patients with high grade malignant glioma, most of whom would not be candidates for clinical trials. No significant financial relationships to disclose.

Hypofractionated Stereotactic Radiosurgery

Abstract Background Nearly all patients with malignant glioma will have disease recurrence. Our purpose was to define the treatment toxicity and efficacy of concurrent bevazicumab (BVZ) with hypofractionated stereotactic radiosurgery (SRS) of relatively larger targets for patients with recurrent MG. Methods A retrospective review of 21 patients with recurrent malignant glioma (18 glioblastoma, 3 WHO grade III glioma), treated at initial diagnosis with surgery and standard chemoradiation, was performed. All patients had concurrent BVZ with hypofractionatedSRS, 30 Gy in 5 fractions, with or without concurrent chemotherapy (temozolomide or CCNU). Results Median patient age was 54 years, median Karnofsky Performance Status was 80, and median target size was 4.3 cm (range, 3.4–7.5 cm). Eleven patients (52%) had previously failed BVZ. One patient had grade 3 toxicities (seizures, dysphasia), which resolved with inpatient admission and intravenous steroids/antiepileptics. Treatment-related toxicities were grade 3 (n = 1), grade 2 (n = 9), and grade 0–1 (n = 11). Kaplan-Meier median progression-free survival and overall survival estimates (calculated from start of SRS) for GBM patients (n = 18) were 11.0 and 12.5 months, respectively. Concurrent chemotherapy did not appear to show any statistically significant efficacy benefit or have any propensity for toxicity. Conclusion BVZ concurrent with hypofractionated SRS was well tolerated by this cohort of patients with relatively larger targets. Ongoing randomized trials with more moderate radiotherapy dosing may help establish the efficacy of this regimen, though intricacies of this approach, including patient selection, radiation target volume delineation/size, and optimal radiation dose, will need further evaluation.

Endothelial Growth Factor

ObjectEndothelial proliferation has been recognized as a marker of high-grade or aggressive glioma. Bevacizumab is a humanized immunoglobulin G1 monoclonal antibody to vascular endothelial growth factor that has been shown to have activity in malignant gliomas when combined with irinotecan. The authors report on a case series of 13 patients with recurrent heavily pretreated malignant glioma that was treated with the combination of bevacizumab and irinotecan.MethodsStandard therapy with primary resection followed by adjuvant chemotherapy and radiation had failed in all patients. The median number of therapies applied, including initial surgery, was 5 (range 3–7 therapies). Nine patients were started on bevacizumab at a dose of 5 mg/kg every 2 weeks. Four patients received bevacizumab at a dose of 10 mg/kg; irinotecan was given at a dose of 125 mg/kg every week for 3 weeks.ResultsOf the 13 treated patients, 10 (77%) had a radiologically demonstrated partial response and 3 (23%) had stable disease. Six patients (46%) had a clinical response. The median time to disease progression while on treatment was 24 weeks. The median overall survival was 27 weeks. The disease progressed in 8 patients, despite an initial response. Five patients are still responding to therapy. Six of the 8 patients whose disease progressed have died. Bevacizumab was discontinued in 2 patients because of nonfatal intracranial bleeding.ConclusionsThe combination of bevacizumab and irinotecan is safe and has excellent activity even in this relapsed, heavily pretreated population of patients with high-grade malignant glioma, most of whom would not be candidates for clinical trials.

PURPOSE: To determine the response rate of the malignant gliomas of childhood to an oral, daily schedule of temozolomide. PATIENTS AND METHODS: A multicenter, phase II evaluation of an oral, daily schedule of temozolomide (200 mg/m2 on 5 consecutive days) was undertaken in children with relapsed or progressive, biopsy-proven, high-grade glioma (arm A) and progressive, diffuse, intrinsic brainstem glioma (arm B). Evidence of activity was defined by radiologic evidence of a sustained reduction in tumor size on serial magnetic resonance imaging scans. RESULTS: Fifty-five patients were recruited (34 to arm A and 21 to arm B) and received 215 cycles of chemotherapy. Grade 3/4 thrombocytopenia was the most frequent toxic event (7% of cycles). Prolonged myelosuppression resulted in significant treatment delays and dose reductions (17% and 22% of cycles, respectively). Two toxic deaths were documented and were related to myelosuppression and sepsis in one patient and pneumonia in a second. The overall (best) response rate was 12% for arm A (95% confidence interval [CI], 3 to 28 in the study cohort, and 2 to 31 for eligible patients) and 5% and 6%, respectively, for arm B (95% CI, 0 to 26 in the study cohort, and 0 to 27 for eligible patients). Stabilization of disease was also documented and was most noteworthy for brainstem gliomas, where two patients achieved both radiologic static disease and discontinued steroid medication. CONCLUSION: Despite moderate toxicity, objective response rates to temozolomide have been low, indicating that temozolomide has minimal activity in the high-grade gliomas of childhood.

9000 Background: In the randomized phase 3 CheckMate 9LA trial (NCT03215706), first-line NIVO + IPI combined with 2 cycles of chemo significantly improved overall survival (OS), progression-free survival (PFS), and objective response rate (ORR) vs chemo alone (4 cycles). Clinical benefit was observed regardless of programmed death ligand 1 (PD-L1) expression level and histology. Here we report data with 2 years’ minimum follow-up from this study. Methods: Adult patients (pts) with stage IV / recurrent NSCLC, ECOG performance status ≤ 1, and no known sensitizing EGFR/ALK alterations were stratified by PD-L1 (< 1% vs ≥ 1%), sex, and histology (squamous vs non-squamous) and were randomized 1:1 to NIVO 360 mg Q3W + IPI 1 mg/kg Q6W + chemo (2 cycles; n = 361) or chemo alone (4 cycles; n = 358). Pts with non-squamous NSCLC in the chemo-alone arm could receive pemetrexed maintenance. The primary endpoint was OS. Secondary endpoints included PFS and ORR by blinded independent central review, and efficacy by different PD-L1 levels. Safety was exploratory. Results: At a minimum follow-up of 24.4 months for OS (database lock: Feb 18, 2021), pts treated with NIVO + IPI + chemo continued to derive OS benefit vs chemo, with a median OS of 15.8 months vs 11.0 months, respectively (HR, 0.72 [95% CI, 0.61–0.86]); 2-year OS rates were 38% vs 26%. Median PFS with NIVO + IPI + chemo vs chemo was 6.7 months vs 5.3 months (HR, 0.67 [95% CI, 0.56–0.79]); 8% and 37% of pts who had disease progression received subsequent immunotherapy, respectively. ORR was 38% with NIVO + IPI + chemo vs 25% with chemo. Similar clinical benefit with NIVO + IPI + chemo vs chemo was observed in all randomized pts and across the majority of subgroups, including by PD-L1 expression level (Table) or histology. Any grade and grade 3–4 treatment-related adverse events were reported in 92% and 48% of pts in the NIVO + IPI + chemo arm vs 88% and 38% in the chemo arm, respectively. Conclusion: With 2 years’ minimum follow-up, first-line NIVO + IPI + chemo demonstrated durable survival and benefit versus chemo in pts with advanced NSCLC; no new safety signals were identified. Clinical trial information: NCT03215706. [Table: see text]

e14019 Background: High-grade glioma (HGG) is the most common malignant brain tumor and lacks effective treatment regimen. Anlotinib is a multikinase inhibitor blocking angiogenesis and tumor cell proliferation simultaneously. This study was performed to evaluate the efficacy and safety of anlotinib alone or in combination with temozolomide (TMZ) in the treatment of recurrent HGG. Methods: This is a single-center, retrospective study. Eligible patients (pts) were diagnosed with pathologically confirmed high grades (WHO III/IV) glioma and had recurrent or progressive disease on or after prior treatment. Other key eligibility criteria included Karnofsky Performance Status (KPS) ≥ 40, aged 16 ̃75 years and having at least one measurable lesion (RANO criteria). Pts were administrated with anlotinib once daily for 14 days every 3 weeks till disease progression, intolerable toxicities or death. The initial dose was 12mg for younger pts ( < 40 years old) with KPS ≥ 60 and 10 mg for others. Combination treatment was allowed if previous TMZ was effective and tolerable. TMZ was administered on dose-dense schedule (150mg/m2, QD, d1-d7 and d15-d21 every 28 days) or metronomic schedule (25-50mg/m2 QD). The primary endpoint was progression-free survival at 6 months (PFS6m) accessed according to RANO criteria. The second endpoints included overall survival (OS), objective response rate (ORR) and disease control rate (DCR). Results: Between August 2019 and June 2020, 23 pts with HGG (15 grade IV; 8 grade III; 12 males, 11 females) were enrolled. The median age and median KPS was 42 years and 60. 16 pts have multifocal or disseminated disease. 18 pts received ≥2 lines previous treatment. At the data cutoff date on September 2020, the median duration of treatment was 9 weeks (range: 3-33). The PFS6m was 39.1% and the median PFS was 4.2 months (95% CI: 2.8, 5.6). The median OS was not reached (95% CI: NE, NE) and the OS at 12 months (OS12m) was 54.8%. 8 pts observed tumor response and 9 pts had stable disease. The ORR and DCR were 34.8% and 73.9% respectively. The results of survival analysis for subgroups were summarized in table below. Grade 1 or 2 treatment-related adverse events (TRAEs) occurred in 65.2% pts. No ≥ grade 3 TRAE was found. All hematological TRAEs occurred in patients received combination regimen. No TRAE-induced treatment termination occurred. The lower incidence of TRAE may partly attributed to that most pts (18/23) received lower initial dose (10mg) of anlotinib and the relatively shorter treatment duration. Conclusions: This study showed treatment with anlotinib alone or in combination with TMZ had promising efficacy and favorable tolerability in patients with recurrent HGG.[Table: see text]

Abstract BACKGROUND Patients with relapse of recurrent glioma have a poor outcome and limited treatment options. The aim of this study is to investigate the clinical benefit and tolerability of weekly intravenous administration of carboplatin-based monotherapy in adult glioma patients who had progressed from previous chemotherapy lines based on temozolomide and nitrosoureas MATERIAL AND METHODS This was a single arm, Phase II study. Eligibility criteria included progressive or recurrent malignant glioma after radiotherapy and chemotherapy-based treatments and Karnofsky Performance Status (KPS) > 60. RESULTS Thirty-two patients (median age: 43.5 y) were enrolled to receive weekly carboplatin monotherapy in intravenous mode of administration. The median duration of response was 7.3 months with an overall disease control rate of 31.3%. Median progression-free survival (PFS) was 2.3 months while overall survival (OS) was 5.5 months. Patients achieving clinical benefit exhibited a longer PFS (4.6 vs 1.5 months; p>0.001) and OS (7.9 vs 3.2 months; p=0.041) compared to those not achieving clinical benefit. CONCLUSION Our findings show that single agent, weekly, intravenous carboplatin may have a role in the treatment patients with recurrent malignant glioma

Major Toxicity

Based on the reports of activity of interferons against metastatic melanomas, we conducted a phase II study of recombinant interferon alfa-2a (Roferon-A, Hoffmann-La Roche, Nutley, NJ) in 66 patients with disseminated melanoma. All patients had excellent Eastern Cooperative Oncology Group (ECOG) performance status (0 to 1), and no evidence of brain metastases. Thirty patients had previously received chemotherapy and the remainder were untreated. The first 35 patients were treated on a daily schedule starting with a Roferon-A dose of 3 X 10(6) U/d and escalating to a maximum of 36 X 10(6) U/d over a period of 12 days. Because of excessive toxicity, the second group of 31 patients were treated on a fixed dose of 18 X 10(6) U/d [corrected] three times weekly (TIW). Among the 62 evaluable patients, five achieved an objective response for a response rate of 8% (95% confidence limits, 3% to 18%). Four patients had minor regressions and eight patients had stability of disease. The responses were evenly distributed between the two dose schedules. The major toxicity of interferon consisted of a constitutional syndrome of anorexia, fever, weight loss, and fatigue, which required a dose reduction in 75% of the patients on the daily schedule. Our data revealed a modest level of activity, which was not influenced by prior treatment or by the dose or schedule of interferon. Because of substantial toxicity with the daily schedule, we recommend a dose of 18 X 10(6) U/d [corrected] if interferon is used in the treatment of patients with melanoma.

This study investigated the antitumor activity and safety of pembrolizumab in patients with recurrent cervical cancer in real-world practice. We conducted a multi-center retrospective study of patients with recurrent or persistent cervical cancer treated with pembrolizumab at sixteen institutions in Korea between January 2016 and March 2020. The primary endpoints were the objective response rate (ORR) and safety. Data were available for 117 patients. The median age was 53 years (range, 28–79). Sixty-four (54.7%) patients had an Eastern Cooperative Oncology Group (ECOG) performance status of ≥2. Forty-nine (41.9%) patients were stage ≥III at diagnosis. Eighty-eight (75.2%) patients had squamous cell carcinoma. The median number of prior chemotherapy lines was two (range, 1–6). During the median follow-up of 4.9 months (range, 0.2–35.3), the ORR was 9.4%, with three complete responses and eight partial responses. The median time to response was 2.8 months (range 1.3–13.1), and the median duration of response (DOR) was not reached. In the population of patients with favorable performance status (ECOG ≤1) (n = 53), the ORR was 18.9%, and the median DOR was 8.9 months (range, 7.3–10.4). Adverse events occurred in 55 (47.0%) patients, including eight (6.8%) patients who experienced grade ≥3 events, and two of them were suspicious treatment-related deaths. Pembrolizumab had modest antitumor activity in patients with recurrent cervical cancer comparable to that found in previously reported clinical trials. However, in patients with favorable performance status, pembrolizumab showed effective antitumor activity. Some safety profiles should be carefully monitored during treatment.

Background: Liposomal irinotecan (nal-IRI) plus 5-fluorouracil and leucovorin (5-FU/LV) was effective and well-tolerated in patients with metastatic pancreatic adenocarcinoma (mPAC) that progressed on gemcitabine-based therapy in the global NAPOLI-1 trial. Real-world data may further clarify the outcomes and safety profile of nal-IRI + 5-FU/LV in clinical practice. Methods: This retrospective analysis included patients with mPAC who received nal-IRI + 5-FU/LV following gemcitabine-based therapy under a Managed Access Program in Korea. Results: From January 2017 to April 2018, 86 patients across 10 institutions received nal-IRI + 5-FU/LV (median age, 61 years; 60% male; ECOG performance status, 0–1). A total of 35 (41%) and 51 (59%) patients had received less than two and two or more lines of chemotherapy before inclusion, respectively. At a median follow up of 6.4 months, median overall survival (OS) was 9.4 months (95% confidence interval [CI] 7.4–11.4) and median progression-free survival (PFS) was 3.5 months (95% CI 1.3–5.7). Six-month OS and PFS rates were 65.1% and 37.5%, respectively. Objective response and disease control rates were 10% and 55%, respectively. Most common grade 3–4 toxicities were neutropenia (37.2%), nausea (10.5%), vomiting (9.3%), anorexia (8.1%) and diarrhoea (4.7%). Conclusion: Real-life data for Korean patients indicate that, consistent with NAPOLI-1, nal-IRI + 5-FU/LV is effective and well-tolerated in patients with mPAC that progressed on gemcitabine-based therapy.

14599 Background: We prospectively conducted a phase II trial to test the efficacy and safety of irinotecan, 5-fluorouracil and leucovorin (FOLFIRI) regimens for the first-line treatment of previously untreated patients with recurrent or metastatic advanced CRC. Methods: Thirty-four previously untreated patients with advanced CRC were enrolled in this study from June 2001 to December 2006. Eligible patients had histologically confirmed adenocarcinoma, no prior systemic therapy in palliative setting, ECOG PS = 2, adequate organ function, written informed consent and at least one measurable disease. The patients received either irinotecan 180 mg/m2 on day 1 with a LV bolus of 200 mg/m2 and a FU bolus of 400 mg/m2, and this was followed by a FU continuous infusion of 600 mg/m2 on day 1 and day 2 (the classic FOLFIRI regimen), or they were treated with a LV bolus of 400 mg/m2 and a FU bolus of 400 mg/m2 followed by a FU continuous infusion of 2,400 mg/m2 for 46 hours (the simplified FOLFIRI regimen), and these treatments were repeated every 2 weeks until disease progression. Results: There were 13 females and 21 males with median age of 54 years (range: 41–79). The most common metastatic sites were lung and liver. A total of 262 cycles were administrated with median 6 cycles per patient (range: 1–22). All pts were evaluable for toxicity, and 30 pts for response to the treatment. The objective response rate was 26.4% with 2 complete responses respectively. Sixteen (47%) pts had stable disease and 7 (20.5%) had a progression. The tumor control rate was 73.4%. The median TTP was 5.3 months, and the overall survival was 10.1 months. The prognostic factor for longer TTP and survival was the ECOG performance status (PS). The type of regimens was not affected on response rate, TTP and survival. The chemotherapy was generally well tolerated and the most common grade 3–4 toxicities were neutropenia, diarrhea. The non- hematological toxicities were similar for both treatment groups, with more frequent grade =3 neutropenia being noted for the simplified FOLFIRI regimen. Conclusions: The FOLFIRI regimen was demonstrated to have a moderate antitumor activity with acceptable toxicity profiles, and tend to show more favorable outcome for patients with good ECOG PS.
