Purpose This study investigated the treatment of primary CNS lymphoma with methotrexate, temozolomide (TMZ), and rituximab, followed by hyperfractionated whole-brain radiotherapy (hWBRT) and subsequent TMZ. The primary phase I end point was the maximum tolerated dose of TMZ. The primary phase II end point was the 2-year overall survival (OS) rate. Secondary end points were preirradiation response rates, progression-free survival (PFS), neurologic toxicities, and quality of life. Patients and Methods The phase I study increased TMZ doses from 100 to 150 to 200 mg/m2. Patients were treated with rituximab 375 mg/m2 3 days before cycle 1; methotrexate 3.5 g/m2 with leucovorin on weeks 1, 3, 5, 7, and 9; TMZ daily for 5 days on weeks 4 and 8; hWBRT 1.2 Gy twice-daily on weeks 11 to 13 (36 Gy); and TMZ 200 mg/m2 daily for 5 days every 28 days on weeks 14 to 50. Results Thirteen patients (one ineligible) were enrolled in phase I of the study. The maximum tolerated dose of TMZ was 100 mg/m2. Dose-limiting toxicities were hepatic and renal. In phase II, 53 patients were treated. Median follow-up for living eligible patients was 3.6 years, and 2-year OS and PFS were 80.8% and 63.6%, respectively. Compared with historical controls from RTOG-9310, 2-year OS and PFS were significantly improved (P = .006 and .030, respectively). In phase II, the objective response rate was 85.7%. Among patients, 66% (35 of 53) had grade 3 and 4 toxicities before hWBRT, and 45% (24 of 53) of patients experienced grade 3 and 4 toxicities attributable to post-hWBRT chemotherapy. Cognitive function and quality of life improved or stabilized after hWBRT. Conclusion This regimen is safe, with the best 2-year OS and PFS achieved in any Radiation Therapy Oncology Group primary CNS lymphoma trial. Randomized trials that incorporate this regimen are needed to determine its efficacy compared with other strategies.

We examined functional outcomes and quality of life of whole brain radiotherapy (WBRT) with integrated fractionated stereotactic radiotherapy boost (FSRT) for brain metastases treatment. Methods Eighty seven people with 1-3 brain metastases were enrolled on this Phase II trial of WBRT (30Gy/10)+simultaneous FSRT, (60Gy/10). Results Mean (Min-Max) baseline KPS, Mini Mental Status Exam (MMSE) and FACT-BR quality of life were 83 (70-100), 28 (21-30) and 143 (98-153). Lower baseline MMSE (but not KPS or FACT-Br) was associated with worse survival after adjusting for age, number of metastases, primary and extra-cranial disease status. Crude rates of deterioration (>10 points decrease from baseline for KPS and FACT-Br, MMSE fall to<27) ranged from 26-38% for KPS, 32-59% for FACT-Br and 0-16%for MMSE depending on the time-point assessed with higher rates generally noted at earlier time points (<6months post-treatment). Using a linear mixed models analysis, significant declines from baseline were noted for KPS and FACT-Br (largest effects at 6 weeks to 3 months) with no significant change in MMSE. Conclusions The effects on function and quality of life of this integrated treatment of WBRT+simultaneous FSRT were similar to other published series combining WBRT+SRS.

Abstract OBJECTIVE There is no standard salvage radiotherapy (RT) regimen, nor a consensus on the concurrent chemotherapy use in CNS lymphoma. We assessed the efficacy of low-dose whole-brain radiotherapy (WBRT) with focal-boost to the area of disease and concurrent temozolomide for the salvage treatment of CNS lymphoma. METHODS A single center retrospective study of CNS lymphoma patients seen between 01/2004 and 02/2019. The inclusion criteria were: diagnosis of CNS lymphoma, age > 18 years at diagnosis, radiation treatment to the brain, and formulation of plan at University of Michigan with at least one follow-up. Overall survival (OS) was determined by Kaplan Meier method. RESULTS Out of 93 patients (median age 58, 45% female), 73% were diagnosed with primary CNS lymphoma (n=68), and the remainder with secondary CNS lymphoma. Radiation modalities were WBRT alone (n=52), low-dose WBRT + focal boost (n=33) and focal RT alone (n=8). Twenty-six patients (28%) received concurrent temozolomide with radiation. Those who received WBRT+boost achieved complete response at a significantly higher rate than those who received WBRT alone (36% vs 17% respectively, p=0.047). The median OS among all groups was 45 months. There was a significant improvement in OS in patients receiving low-dose WBRT+boost compared to WBRT alone (median 65 vs 14 months respectively, p=0.016). OS was significantly longer in patients who received concurrent temozolomide than in those who did not (median 86 vs 23 months respectively, p=0.0287). CONCLUSIONS In CNS lymphoma salvage RT, a longer survival was observed with low-dose WBRT with focal-boost compared to WBRT alone, as well as with concurrent temozolomide. This result is limited by the selection bias to each of the treatment groups; however, the low-dose WBRT with focal-boost and concurrent temozolomide is a useful salvage alternative to standard WBRT as it may reduce long-term neurocognitive toxicity.

PURPOSE: Two phase I studies of the oxaliplatin and irinotecan combination were performed in advanced gastrointestinal cancer patients to characterize the safety and pharmacokinetics of the regimen. PATIENTS AND METHODS: Patients with a performance status (PS) of ≤2 and normal hematologic, hepatic, and renal functions received oxaliplatin (2-hour intravenous infusion) followed 1 hour later by irinotecan administered over a 30-minute period, every 3 weeks. Dose levels that were explored ranged from 85 to 110 mg/m2 for oxaliplatin and 150 to 250 mg/m2 for irinotecan. Plasma pharmacokinetics of total and ultrafiltrable platinum, irinotecan, SN-38, and its glucuronide, SN-38G, were determined. RESULTS: Thirty-nine patients with gastrointestinal carcinomas (24 with colorectal cancer [CRC], four with pancreas cancer, four with gastric cancer, three with hepatocarcinoma, and four with other) received 216 treatment cycles. Median age was 54 years (range, 21 to 72 years); 95% had PS of 0 to 1; all but six had failed fluorouracil (5-FU) chemotherapy. The maximum-tolerated dose was oxaliplatin 110 mg/m2 plus irinotecan 200 mg/m2 in one study and oxaliplatin 110 mg/m2 plus irinotecan 250 mg/m2 in the other study. Grade 3 to 4 diarrhea and febrile neutropenia were dose-limiting toxicities; other toxicities included emesis and dose-cumulative neuropathy. Recommended dose for phase II studies is oxaliplatin 85 mg/m2 and irinotecan 200 mg/m2. At this dose (12 patients, 65 cycles), grade 3 and 4 toxicities per patient included the following: emesis in 42% of patients, neutropenia in 33% (febrile episodes in 17%), peripheral neuropathy in 25%, delayed diarrhea in 17%, and thrombocytopenia in 8%. Two patients with Gilbert's syndrome experienced severe irinotecan toxicity. No plasmatic pharmacokinetic interactions were detected. Seven partial responses were observed in 24 CRC patients. CONCLUSION: This combination is feasible, with activity in 5-FU–resistant CRC patients. Phase I studies that explore the every-2-weeks schedule, in addition to phase II studies of this schedule (as well as in combination with 5-FU) as second-line therapy of metastatic CRC, are ongoing.

e15023 Background: To investigate S-1 and irinotecan (CPT-11) combination as an alternative to infusional 5- fluorouracil/leucovorin plus CPT-11, we performed a phase I/II trial to determine maximum tolerated dose (MTD), efficacy and toxicity in metastatic or recurrent colorectal cancer. In addition, we evaluated the association between genotypes of candidate genes and phenotypes. Methods: S-1 was administered orally at a dose of 70 mg/m2 (level I-III) or 80 (IV and V) from day 1 to 14. CPT-11 was given i.v. on day 1, stepping up to 175 (level I), 200 (II), 225 (III and IV) or 250 (V) mg/m2 . The treatment was repeated every 3 weeks. The association of the UGT1A1 genotypes (*6, *28, and *60) and CYP2A6 genotypes (*4, *7, and *9) with toxicities or efficacy were analyzed in patients who participated in phase II portion. Results: Twenty-three patients entered the phase I and 30 enrolled in phase II study. The MTD of S-1 and CPT-11 was considered to be 80 mg/m2 and 250 mg/m2, respectively. The dose-limiting toxicities (DLTs) were diarrhea and neutropenia. The recommended dose (RD) was determined at a S-1 dose of 80 mg/m2 and a CPT- 11 dose of 225 mg/m2. The overall response rate was 66.7% (95% CI, 48.7–84.6) at the RD level. Median time to progression was 7.6 months (95 % CI, 5.7–9.5). Median survival time was not reached. Grade3–4 neutropenia was observed in 53.4% of the patients. Grade 3–4 nonhematologic toxicities were diarrhea (16.7%) and asthenia (6.7%). The frequencies of UGT1A1*60, *28, and *6 allele were 25.8%, 10.3%, and 15.5%, respectively. Homozygous for *28 or *6 were not observed. All three double heterozygous for *28 and *6 experienced grade 3–4 neutropenia. The allele frequencies of CYP2A6*4, *7, and *9 were 15.5%, 8.6%, and 29.3%, respectively. There were no association between CYP2A6 genotypes and response rates or toxicities. Conclusions: The combination of S-1 and CPT-11 was effective and had manageable toxicities in patients with metastatic or recurrent colorectal cancer.

2544 Background: C-Met protein is a receptor tyrosine kinase which is overexpressed or mutated in a variety of tumor types, causing cell proliferation, metastasis, and angiogenesis. Tivantinib is an orally bioavailable small molecule which binds to the c-Met protein. This phase I study was designed to determine the maximum tolerated dose (MTD) of tivantinib in combination with standard dose FOLFOX for the treatment of patients with advanced solid tumors. Methods: Patients with advanced solid tumors for which FOLFOX (5-FU IV 400 mg/m2 day 1; 5-FU CIV 2400 mg/m2 day 1; Leucovorin IV 400 mg/m2 day 1; Oxaliplatin IV 85 mg/m2 day 1) would be appropriate chemotherapy received escalating doses of tivantinib BID (days 1-14) in a standard 3 + 3 design. Dose-limiting toxicities (DLTs), non-dose-limiting toxicities (NDLTs), safety, and preliminary efficacy were evaluated. Results: Fourteen patients (50% colorectal) were treated across 3 dose levels: 120 mg (n=3); 240 mg (n=5); 360 mg (n=6). No DLTs were observed until the 3rd dose level (treatment delay ≥3 days, secondary to grade 3 neutropenia). Common related adverse events (% grade 1/2; % grade 3/4) included: diarrhea (36%; 0%), neutropenia (0%; 29%), nausea (14%; 14%), vomiting (14%; 14%), dehydration (14%; 7%), and thrombocytopenia (14%; 0%). To date, 7 patients have been evaluated for response including 4 (57%) with stable disease evident at the 8-week evaluation (CRC, 2 patients; unknown primary favoring CRC, 1 patient; esophageal, 1 patient) and 3 (21%) with disease progression. The 4 patients with stable disease are continuing on treatment; three (CRC and unknown primary) had received prior FOLFOX. Conclusions: The addition of tivantinib to standard therapy FOLFOX appears tolerated up to its recommended phase II monotherapy dose of 360 mg. Preliminary efficacy is encouraging, and a phase II study is proceeding with this regimen for the first line treatment of advanced gastroesophageal patients. Clinical trial information: NCT01611857.
