6529 A phase II study on the efficacy and toxicity of cabozantinib in recurrent/metastatic salivary gland cancer patients. Background: Because c-MET and VEGFR are often overexpressed in salivary gland cancer (SGC), this study evaluated the efficacy and safety of cabozantinib in recurrent/metastatic (R/M) SGC pts. Methods: A single center, single arm, phase II study was conducted. Immunohistochemical c-MET positive (H-score ≥10) R/M SGC pts were included in 3 cohorts: adenoid cystic carcinoma (ACC), salivary duct carcinoma (SDC), and other SGCs. Objective growth or complaints due to the disease were required before inclusion in the ACC and other SGC cohort. No prior systemic treatments were required. Pts started 60 mg cabozantinib tablets OD. Primary endpoint was the objective response rate (ORR). A Simon two-stage design was used. In case of ≥1 objective response in the first 9 pts/cohort, 8 additional pts would be included in the cohort. Results: In total 25 pts were included from Sep. 2018 until premature closure due to severe toxicity in Nov. 2019. Median age was 56 years (range 49-72), prior treatments included: primary tumor resection ( n=19), radiotherapy ≥50Gy ( n=24), systemic therapy ( n=10; adjuvant in 2 pts, palliative in 8 pts). Six pts had grade 3 ( n=4), grade 4 ( n=1), or grade 5 ( n=1) wound/fistula complications, occurring at a median of 7.2 mths on cabozantinib (range 2.1-12.8). This resulted in a severe wound complication rate of 32% in 19 pts on treatment for ≥2 mths. Remarkably, 4 out of 6 pts developed this complication in the area exposed to high-dose Rx; 2/4 had a pre-existing fistula in this area. Median interval between Rx and start of cabozantinib was 71.3 mths (range 10.6-94.7). Other grade ≥3 adverse events in >1 pt were: hypertension (5 pts), diarrhoea (2 pts) and dehydration (2 pts). Current median follow-up is 6.8 mths. The ORR was 6% (1/17 pts) in the ACC cohort, 20% (1/5 pts) in the SDC cohort, and 0% (0/3 pts) in other SGC pts; median PFS is 12.6 mths (95% CI 6.8 – 18.4 mths), 9.0 mths (insufficient events for 95% CI), and 6.9 mths (95% CI 0 – 15.2 mths), respectively. Median OS is not reached in any cohort. Conclusions: This phase II study on cabozantinib in R/M SGC pts demonstrated severe wound and fistula complications in 32% of pts on treatment for ≥2 mths, mostly (4/6 pts) within the radiotherapy field. Because of this toxicity the study was closed prematurely. Furthermore, cabozantinib showed minimal clinical activity in SGC pts.

PURPOSE Docetaxel (Taxotere, Rhone-Poulenc Rorer, Antony, France) and cisplatin are two of the most active single agents used in the treatment of non-small-cell lung cancer (NSCLC). A recently reported phase I study of the combination of docetaxel and cisplatin recommended a dose of 75 mg/m2 of both drugs every 3 weeks for subsequent phase II study. PATIENTS AND METHODS Eligible patients were aged 18 to 75 years with a World Health Organization (WHO) performance status < or = 2 and life expectancy > or = 12 weeks, with metastatic and/or locally advanced NSCLC proven histologically or cytologically. Patients were not permitted to have received prior chemotherapy, extensive radiotherapy, or any radiotherapy to the target lesion and must have had measurable disease. Concurrent treatment with colony-stimulating factors (CSFs) or prophylactic antibiotics was not permitted. Docetaxel (75 mg/m2) in 250 mL 5% dextrose was given intravenously (i.v.) over 1 hour immediately before cisplatin (75 mg/m2) in 500 mL normal saline given i.v. over 1 hour in 3-week cycles. Premedication included ondansetron, dexamethasone, promethazine, and standard hyperhydration with magnesium supplementation. RESULTS A total of 47 patients, two thirds of whom had metastatic disease, were entered onto this phase II study. The majority of patients were male (72%) and of good (WHO 0 to 1) performance status (85%). All 47 patients were assessable for toxicity and 36 were for response. Three patients were ineligible and eight (17%) discontinued treatment because of significant toxicity. In assessable patients, the overall objective response rate was 38.9% (95% confidence limits [CL], 23.1% to 56.5%), 36.1% had stable disease, and 25% progressive disease. On an intention-to-treat analysis, the objective response rate was 29.8%. Median survival was 9.6 months and estimated 1-year survival was 33%. Significant (grade 3/4) toxicities included nausea (26%), hypotension (15%), diarrhea (13%), and dyspnea mainly related to chest infection (13%). One patient experienced National Cancer Institute (NCI) grade 3 neurosensory toxicity after eight cycles. Grade 3/4 neutropenia was common and occurred in 87% of patients, but thrombocytopenia > or = grade 3 was rare (one patient). Significant (grade 3/4) abnormalities of magnesium levels were common (24%). Febrile neutropenia occurred in 13% of patients and neutropenic infection in 11%, contributing to two treatment-related deaths. No neutropenic enterocolitis or severe fluid retention was reported. CONCLUSION Compared with other active regimens used in this setting, the combination of docetaxel and cisplatin in advanced NSCLC is an active regimen with a similar toxicity profile to other combination regimens.

SummaryBackground Preclinical evidence has suggested that a subset of pancreatic cancers with the G12R mutational isoform of the KRAS oncogene is more sensitive to MAPK pathway blockade than pancreatic tumors with other KRAS isoforms. We conducted a biomarker-driven trial of selumetinib (KOSELUGO™; ARRY-142886), an orally active, allosteric mitogen-activated protein kinase 1 and 2 (MEK1/2) inhibitor, in pancreas cancer patients with somatic KRASG12R mutations. Methods In this two-stage, phase II study (NCT03040986) patients with advanced pancreas cancer harboring somatic KRASG12R variants who had received at least one standard-of-care systemic therapy regimen received 75 mg selumetinib orally twice a day until disease progression or unacceptable toxicity occurred. The primary outcome of the study was best objective response (BOR). Results From August 2017 to February 2018 a total of 8 patients with confirmed somatic KRASG12R mutations and a median age of 61.5 years were treated with selumetinib. Seven out of eight (87.5%) had received two or more lines of prior systemic chemotherapy. After a median follow-up period of 8.5 months (range 2 to 20), three patients had stable disease for more than 6 months while receiving selumetinib. No patients achieved an objective partial response. Median progression-free survival (PFS) was 3.0 months (95% CI, 0.8–8.2) and median overall survival (OS) 9 months (95% CI, 2.5–20.9). Conclusion This study in heavily pre-treated pancreatic adenocarcinoma patients suggests alternative strategies beyond single agent MEK inhibition are required for this unique, molecular subset of pancreatic cancer patients. The trial was registered on February 2nd, 2017 under identifier NCT03040986 with ClinicalTrials.gov.

PURPOSE Targeted therapies against non–small-cell lung cancer (NSCLC) harboring HER2 mutations remain an unmet need. In this study, we assessed the efficacy and safety of pyrotinib in patients with HER2-mutant advanced NSCLC in a prospective, multicenter, open-label, single-arm, phase II study. PATIENTS AND METHODS Patients with stage IIIB or IV HER2-mutant lung adenocarcinoma who were previously treated with platinum-based chemotherapy were enrolled to receive pyrotinib at a dose of 400 mg/d for 21-day cycles. The primary end point was objective response rate per independent review committee (IRC). RESULTS Between October 20, 2016, and December 10, 2018, 60 patients received pyrotinib monotherapy. At baseline, 58 (96.7%) were stage IV, and 25 (41.7%) received at least 2 lines of prior chemotherapy. As of data cutoff on June 20, 2019, IRC-assessed objective response rate was 30.0% (95% CI, 18.8% to 43.2%). All subgroups of patients with different HER2 mutation types showed a favorable objective response rate. The objective response rates were similar between patients with and without brain metastases (25.0% v 31.3%). The median duration of response was 6.9 months (95% CI, 4.9 to 11.1 months). The median progression-free survival was 6.9 months (95% CI, 5.5 to 8.3 months) per IRC. The median overall survival was 14.4 months (95% CI, 12.3 to 21.3 months). Treatment-related adverse events of grade 3 or 4 occurred in 28.3% of patients, with the most common being diarrhea (20.0%; all grade 3). No treatment-related deaths were reported. CONCLUSION Pyrotinib showed promising antitumor activity and an acceptable safety profile in chemotherapy-treated patients with HER2-mutant NSCLC.

PurposeTo evaluate the efficacy and safety of ixabepilone in patients with metastatic breast cancer (MBC) resistant to anthracycline, taxane, and capecitabine, in this multicenter, phase II study.Patients and MethodsPatients with measurable disease who had tumor progression while receiving prior anthracycline, taxane, and capecitabine were enrolled. Ixabepilone 40 mg/m2monotherapy was administered as a 3-hour intravenous infusion on day 1 of a 21-day cycle. The primary end point was objective response rate (ORR), assessed by an independent radiology facility (IRF).ResultsA total of 126 patients were treated and 113 were assessable for response. Patients were heavily pretreated: 88% had received at least two lines of prior chemotherapy in the metastatic setting. IRF-assessed ORR was 11.5% (95% CI, 6.3% to 18.9%) for response-assessable patients. Investigator-assessed ORR for all treated patients was 18.3% (95% CI, 11.9% to 26.1%). Fifty percent of patients achieved stable disease (SD); 14.3% achieved SD ≥ 6 months. Median duration of response and progression-free survival were 5.7 and 3.1 months, respectively. Median overall survival was 8.6 months. Patients received a median of 4.0 treatment cycles (range, one to 16 cycles), and 25% of patients received ≥ eight cycles. Grade 3/4 treatment-related events included peripheral sensory neuropathy (14%), fatigue/asthenia (13%), myalgia (8%), and stomatitis/mucositis (6%). Resolution of grade 3/4 peripheral sensory neuropathy occurred after a median period of 5.4 weeks.ConclusionIxabepilone demonstrated clear activity and a manageable safety profile in patients with MBC resistant to anthracycline, taxane, and capecitabine. Responses were durable and notable in patients who had not previously responded to multiple prior therapies.

18179 Background: Because elderly pts may tolerate platinum-based combination chemotherapy poorly, single-agent chemotherapy is selected for the treatment regimen. However, retrospective subgroup analyses have consistently indicated that elderly pts indeed benefit from platinum-based combination chemotherapy as well as their younger counterparts. This phase II study evaluated the efficacy and safety of carboplatin-gemcitabine combination chemotherapy in elderly pts with advanced NSCLC. Methods: Fifty-four pts aged more than 70 years old (median, 77; range, 70–88) with previously untreated advanced NSCLC were enrolled on this trial. Additional criteria included the presence of measurable lesions, an Eastern Cooperative Oncology Group performance status of 0 or 1, and adequate organ function. Pts received carboplatin at an area under the curve of 4 mg/ml/min on the first day and gemcitabine at 1000 mg/m2 on the first and eighth day of consecutive 3 week periods. The primary endpoint was to determine the objective response rate of this platinum-doublet regimen. The RECIST criteria were used to measure response. Results: Enrolled pts included 15/39 with stage IIIB/IV diseases. Fifty-one out of enrolled pts were eligible for efficacy and safety analyses. The median number of treatment cycles was 4 (range, 1–7). Fifteen partial responses (response rate: 29%) were obtained. The median TTP was 118 days. Hematological toxicities of grade 3/4 included leukopenia (46%), neutropenia (72%) and thrombocytopenia (50%). Non-hematological toxicities of grade 3/4 included nausea (6%), appetite loss (7%), fatigue (7%) and infection (9%). Conclusions: The combination carboplatin-gemcitabine at these doses has shown activity with a favorable toxicity profile for fit elderly pts with advanced NSCLC.

5576 Background: Endometrial cancer (EC) is the most common gynecologic malignancy. Vascular endothelial growth factor (VEGF) overexpression in EC correlates with poor outcome, thus targeting VEGF is a rational therapeutic approach. We have conducted a two-stage open-label phase II study in advanced EC with sunitinib, an oral tyrosine kinase inhibitor of multiple VEGF receptors. Methods: Eligible pts have recurrent or metastatic EC and have received up to 1 prior chemotherapy (CT) regimen for metastatic disease. Sunitinib is given at 50 mg daily (OD) for 4 consecutive weeks (wks) followed by 2 wks off. Dose could be reduced to 37.5 mg OD and then 25 mg OD in the setting of toxicity. Imaging is repeated every 12 wks. Primary objectives are objective response rate (ORR by RECIST) and rate of 6-month progression-free survival (PFS). If 1 or more responses occur in the first 15 evaluable pts, the study would continue to a second stage (total = 30 pts). Secondary objectives are time to progression (TTP), overall survival (OS), and safety. Results: We report the results of the first stage of this study. Sixteen pts have been treated (median age: 63; range 41–74) with 37 cycles of sunitinib (median 2; range: 1–7). Baseline ECOG PS was 0 (7 pts), 1 (8 pts), or 2 (1 pt). Histology was endometrioid (7 pts), serous (5 pts), clear cell (1 pt), or mixed/other (3 pts). Most pts had high-grade histology (G3: 8; G2: 4; G1: 2; GX: 2). Nine pts had prior adjuvant CT, 8 pts had 1 prior CT for advanced EC, 4 pts had prior hormones and 7 pts had prior radiotherapy. Partial response was achieved by 2 pts (ORR = 12.5%), and 2 other pts had a best response of stable disease; 3 of these pts remained progression-free > 6 months. Median TTP = 2.5 months (95% CI: 2.47-NR), and median OS = 6.2 months (95% CI: 5.1-NR). Grade 3/4 adverse events (AE) in >10% of pts were fatigue (7 pts, 44%) and hypertension (5 pts, 31%). Dose reduction was required for 11 of 16 pts (69%). Two pts were inevaluable after receiving <2 cycles due to AE (grade 4 hyponatremia; grade 3 fatigue) and 1 other pt has yet to complete 2 cycles. Conclusions: Sunitinib shows preliminary activity in EC. This trial will proceed to a second stage of accrual to further explore the efficacy and safety of sunitinib in advanced EC.

2063 Background: Meningiomas account for 15%-18% of CNS tumors. Although benign, recurrence is seen in 16%-39% of cases, depending on the extent of resection possible. Tumor location may make further resection hazardous. Chronic hydroxyurea (HU) was reported to produce well documented objective responses in a small series of patients, with gradual regression occurring over 6–10 months. Induction of apoptosis was furthermore demonstrated with HU in primary benign meningioma explant cultures. The S9811 phase II trial was undertaken to estimate the objective response rate, if any, of unresectable benign meningioma to this HU regimen. Methods: Eligibility required unresectable, measurable, residual or recurrent, histologically-proven benign meningioma. Progressive tumor or progressive neurologic deficit was required. No prior cytotoxics, no radiation therapy for >1 year. Age > 18, adequate hematologic reserve, PS 0–2. HU 20 mg/kg/day po was given for up to 2 years if there was no progressive disease. Single-stage accrual of 38 pts would have allowed detection of 5% null hypothesis response probability vs. 20% with 90% power; the 28 pts actually accrued provide 81% power. Results: Between November 98 and June 2005, 29 pts were accrued, with study closure due to slow accrual. 1 ineligible. Response assessment showed CR+PR 0% (95% CI 0–12%); SD 71% (95% CI 51–87%); PD 21% (95% CI 8–41%); undetermined 7%. Median PFS was 27 months. (95% CI 12–29 months.); 3-year PFS 43% (95% CI 25–61%). Median OS has not been reached. Seven patients were removed from study for toxicity (5/7 hematological). Toxicity was mainly hematologic: 11/28 (39%) grade 3, 2/28 (11%) grade 4. Grade 3 non-hematologic toxicity was seen in 7/28 (25%). Conclusions: Chronic HU therapy for unresectable benign meningioma resulted in an estimated objective response rate of < 12%. Whether the stable disease rate seen differs in any way from what can be expected from the natural history of meningioma cannot be determined from this phase II study design. No significant financial relationships to disclose.

Recurrent Gbm

2051 Background: Glioblastoma (GBM) is the most aggressive malignancy of the central nervous system. The majority of GBM have genetic changes that increase the activity of the phosphatidylinositol-3-OH kinase (PI3K) signal transduction pathway, critical for cell motility, proliferation, and survival. We present the interim results of PX-866, an oral PI3K inhibitor, in patients (pts) with recurrent GBM. Methods: Pts with histologically confirmed GBM at first recurrence after treatment with chemoradiation and adjuvant temozolomide are given PX-866 8 mg daily on this single-arm phase II study. MRI and clinical exam are done every 8 weeks to determine treatment response. The trial has a 2-stage design with dual endpoints of objective response and early progression (within 8 weeks). In Stage I, 15 pts are evaluated and if 0 responses and 10 or more early progressions are seen, enrolment will stop. Otherwise, Stage II will enrol another 15 pts for efficacy analysis. Tumour tissue is collected for analysis of potential markers of PI3K inhibitory activity (PTEN, EGFRvIII, PIK3CA mutations). Results: Seventeen pts have been enroled to date: 14 evaluable for response and 15 for toxicity. Median age was 54 years (range 35-70), with 7 females and 10 males. No pts had received treatment for recurrent GBM, and median time between initial diagnosis and study enrolment was 300 days (range: 113-447 days). Pts have received a median of one 8-week cycle of PX-866 (range: 1-4). Twelve pts have discontinued therapy, 9 due to disease progression and 3 due to grade 3/4 liver enzyme abnormalities. Other adverse effects have included fatigue (10 pts/1 grade 3), diarrhea (6 pts/3 grade 3), nausea (7 pts/0 grade 3), vomiting (6 pts/0 grade 3), lymphopenia (14 pts/3 grade 3). Stage I response data are premature; it is not yet known if the trial will continue to Stage II. Archival tissue is available on all patients and is undergoing analysis. Conclusions: This is one of the first trials of a PI3K inhibitor in pts with recurrent GBM. PX-866 has been relatively well tolerated. Stage I response data are premature; while it is not yet known if the criteria will be met to continue to Stage II, prolonged SD has been observed in some pts. The correlative biomarker assays underway will be important to understand this observation.
