PURPOSE The camptothecin derivative irinotecan has demonstrated clinical activity in metastatic colorectal carcinoma in both chemotherapy-naive and fluorouracil-refractory patients. 9-Aminocamptothecin (9-AC; NSC 603071), another camptothecin derivative, was selected for clinical development based on preclinical activity, including cures in human tumor xenografts resistant to standard anticancer agents. We report a phase II trial of 9-AC in patients with previously untreated metastatic colorectal carcinoma. PATIENTS AND METHODS Colorectal cancer patients with measurable disease, a performance status of 0 to 2 (Zubrod), and no prior chemotherapy for metastatic disease received 9-AC. A cycle of therapy was 35 microg/m2/h for 72 consecutive hours (840 microg/m2/d for 3 days) and rest on days 4 to 14; a course of therapy was defined as two cycles (28 days). Patients were assessed for response after two courses. RESULTS Seventeen patients with metastatic colorectal cancer were entered onto this trial. No complete or partial responses were noted. Treatment was well tolerated; toxic effects consisted mainly of neutropenia, nausea, vomiting, stomatitis, fatigue, and anemia. Grade 3 to 4 toxicity was limited to neutropenia (grade 3 in four patients and grade 4 in six), anemia (grade 3 in two patients), and vomiting (grade 3 in two patients). No grade 3 or 4 diarrhea occurred. Only two patients had their 9-AC dose reduced to 30 microg/m2/h. The median nadir absolute granulocyte count (AGC) was 1,500/microL. The median number of courses given was two and the median time to disease progression was 8 weeks. CONCLUSION At the dose and schedule used in this trial, 9-AC lacked antitumor activity in metastatic colorectal cancer. 9-AC infusion schedules of longer duration are currently being investigated in this disease.

560 Background: Everolimus (E) is an oral inhibitor of mTOR. Tivozanib (T) is a highly potent, selective, oral inhibitor of VEGF receptors-1, -2, and -3. Preclinical data suggest antitumor activity for this combination in colorectal cancer. We therefore performed a multicenter Phase Ib trial of E + T in patients (pts) with any refractory gastrointestinal (GI) malignancy, followed by a Phase II trial of E + T in pts with refractory, metastatic colorectal cancer (mCRC). Methods: Eligibility criteria: histologically confirmed, measurable disease; ECOG PS≤2; blood pressure ≤150/100; no venous thromboembolism within prior 6 months. Pts with mCRC must have received prior fluoropyrimidine, irinotecan, oxaliplatin, bevacizumab and anti-EGFR antibody (if KRAS wt). E was administered once daily continuously. T was administered once daily for 3 out of every 4 weeks. The Phase Ib study in pts with any GI malignancy followed a standard 3+3 design with 3 dose levels: (1) E 5 mg/d + T 1 mg/d; (2) E 10 mg/d + T 1 mg/d; (3) E 10 mg/d + T 1.5 mg/d. The Phase II study in pts with mCRC was a non-randomized, one-stage design with a primary endpoint of progression-free survival. Results: Between 02/10-12/10, 12 pts were enrolled to the Phase Ib study. Median age, 60 (39-81) years; male, 50%; ECOG PS 0/1/2, 42/58/0%; tumor types: esophagus 1, colorectal 11 pts. Dose limiting toxicities of grade 3 fatigue and grade 3 fatigue/ dehydration occurred in 2/6 pts on dose level 3. Grade 3/4 treatment-related adverse events in ≥10% of pts were dehydration, fatigue, headache, hyperglycemia, hypertension, and hypophosphatemia. The phase II study proceeded at the maximally tolerated dose (MTD) of E 10 mg/d and T 1 mg/d. Between 02/11-06/11, 40 pts with mCRC were enrolled to the phase II study. All but 1 pt received prior bevacizumab. Median age, 56 (35-81) years; male, 48%; ECOG PS 0/1/2, 45/53/2%. Treatment is ongoing. Conclusions: Among pts with refractory GI malignancies, the combination of Everolimus + Tivozanib was well-tolerated with MTD of E 10 mg/d and T 1 mg/d. A phase II trial has completed enrollment using these doses of E + T in pts with refractory mCRC; safety and efficacy data will be available for presentation.

e15053 Background:The role of combination chemotherapy plus anti-EGFR treatment in older patients with metastatic colorectal cancer (mCRC) is unclear. We conducted an open label phase II trial in order to evaluate the safety and efficacy of modified FOLFIRI plus panitumumab as first-line treatment in elderly patients with RAS wild-type mCRC. Methods: Patients ≥70 years old with unresectable all-RAS wild-type mCRC were treated with Panitumumab 6mg/kg as 60min iv infusion followed by Irinotecan 130mg/m2 as 90min iv infusion, Leucovorin 400mg/m2 as 2h iv infusion and 5-Fluorouracil 400mg/m2 as bolus iv infusion on day 1 and 5-Fluorouracil 1.200 mg/m2 as continuous iv infusion for 46h, every 2 weeks. Sample size calculation was based on the minimax Simon two-step design: The null hypothesis was that the overall response rate (ORR) is ≤ 30% versus the alternative hypothesis of ORR ≥ 50% (α = 0.05, power 80%). Results: Forty-six patients were enrolled in the study. Two patients did not receive treatment because they were RAS mutant. Median age for the 44 treated patients was 76 years (range 70-88). Males were 32 and the PS was 0, 1 and 2 in 25%, 70.5% and 4.5% of patients, respectively. Rectal cancer accounted for 25% while 15.9% of patients had the primary tumour in situ. Twenty-one partial responses were observed for an ORR of 47.7% (95%CI: 32.9%-62.5%) while seven patients (15.9%) had stable disease. After a median follow-up of 36.0 months, the median progression-free survival was 6.1 months (95%CI: 3.6-8.7) and the median overall survival was 20.9 months (95%CI: 11.7-30.1). Grade 3-4 neutropenia was recorded in 4 (9%) and grade 3-4 diarrhea in 9 (20.4%) patients while one patient had a grade 4 bowel perforation. One patient experienced grade 3 mucositis, two patients grade 3 skin toxicity and two patients grade 3 fatigue. There were no toxic deaths while one patient died due to bowel obstruction and one due to postoperative complications after removal of the primary tumor. Conclusions: The modified FOLFIRI plus panitumumab combination presented significant efficacy with manageable toxicity in elderly patients with mCRC.

3591 Background: DJ-927, a novel oral tubulin depolymerization inhibitor, causes apoptosis and DNA cell division arrest. It is not a substrate for the MDR and has excellent activity in preclinical colorectal cancer models. Methods: We are conducting a two-stage, multi-center, phase II trial to assess the efficacy of DJ-927 administered initially as second-line therapy following failure of irinotecan or oxaliplatin based therapy (n= 39). DJ-927 is given as a single oral dose on day 1 of a 21-day cycle at a dose range of 27 - 35 mg/m2. Results: Thirty-nine patients were enrolled, including 14 with prior irinotecan based therapy and 25 who had received prior oxaliplatin therapy. The median age was 56 years (range: 30–87) and the median ECOG PS at baseline was 1 (range: 0–2). A total of 155 courses (range: 1–24) have been administered with a median of 2 courses. Nine patients required dose reduction due to toxicity. Thirty-seven patients were evaluable for efficacy. There were 2 CRs and 2 PRs (10.3%) reported that were confirmed as per RECIST criteria. Fourteen patients (35.9%) had SD, including 6 patients (15.4%) with SD >12 weeks. The most common Grade 3 or 4 AEs were neutropenia (48.7%), fatigue (10.3%), neuropathy (7.8%), and nausea (5.0%).Six patients experienced febrile neutropenia, all requiring hospitalization but tolerated treatment with subsequent dose reduction. There were 13 episodes (33.3%) of peripheral neuropathy reported; however, only 3 (7.8%) were grade 3 or 4. Six patients withdrew due to adverse events. Conclusions: The results of this study indicate activity of DJ-927 as second line therapy in patients with metastatic colorectal cancer. Severe toxicity was generally limited to reversible neutropenia and peripheral neuropathy. This novel oral agent is well tolerated and warrants further evaluation in combination with other active agents. [Table: see text]

Purpose In a multicenter, double-blind phase II trial, we compared the efficacy and safety of perifosine plus capecitabine (P-CAP) with placebo plus capecitabine (CAP) in patients with metastatic colorectal cancer (mCRC) who had progressed after as many as two prior therapies. Patients and Methods Patients (n = 38) not previously treated with capecitabine received P-CAP (perifosine 50 mg orally once daily, days 1 to 21 and CAP 825 mg/m2 orally twice daily, days 1 to 14) or CAP (825 mg/m2 orally twice daily, days 1 to 14) in 21-day cycles until disease progression. The primary end point was time to progression (TTP). Secondary end points included overall survival (OS), overall response rate (ORR), safety, and tolerability. Results Twenty patients were randomly assigned to P-CAP and 18 to CAP. Median TTP (27.5 v 10.1 weeks; P < .001) and median OS (17.7 v 7.6 months; P = .0052) were improved in patients receiving P-CAP versus CAP. ORR was 20% v 7% in the P-CAP and CAP groups, respectively, and one patient in the P-CAP group had a complete response. A subset analysis of fluorouracil-refractory patients showed a median TTP of 17.6 v 9.0 weeks (P < .001) and median OS of 15.1 v 6.5 months (P = .0061). Toxicities, including diarrhea, nausea, fatigue, and hand-foot syndrome, were manageable. Conclusion P-CAP showed promising clinical activity compared with CAP in previously treated patients with mCRC. A phase III trial is underway comparing P-CAP with CAP in patients with refractory mCRC.

627 Background: Regorafenib improves survival in refractory metastatic colorectal cancer (mCRC), but alternative chemotherapy is required to avoid severe toxicity. S-1+oral leucovorin (SL) has shown promising results in untreated mCRC without severe toxicity. TML trial demonstrated that continuation of bevacizumab (Bev) after progression prolongs overall survival. Thus, we hypothesized that combination chemotherapy of SL/Bev would be beneficial; we conducted a single-center phase II trial to assess the efficacy and safety of SL/Bev as a salvage therapy in mCRC. Methods: Major eligibility criteria were: mCRC with confirmed adenocarcinoma diagnosis; age > 20 years; ECOG performance status, 0–2; and progression after administration or intolerance to approved drugs for mCRC (5-FU, oxaliplatin, irinotecan, Bev, and anti-EGFR antibody, if KRAS wild-type). S-1 (80–120 mg/body) and leucovorin (25 mg) were orally administered for 1 week followed by 1 week rest. Bev (5 mg/kg) was administered on day 1 of every 2-week cycle. Primary endpoint was disease control rate (DCR). Results: Twenty-three patients were enrolled: 8 (35%) females; median age, 70 years (range, 38–78); and 14 (61%) with KRAS wild-type. DCR was 65% [95% confidence interval (CI), 41.3–82.7%] and response rate was 6% (95% CI, 1.1–27.0%). One patient experiencing partial response to SL/Bev had BRAF mutant tumor with primary resistance to XELOX+Bev as first-line and irinotecan+cetuximab as second-line chemotherapy. Median progression-free and overall survival period were 4.1 and 9.5 months, respectively. Major adverse events were mucositis, (grade 3, 12%), diarrhea (grade 3, 12%), and decreased hemoglobin (grade 3, 12%). Conclusions: SL/Bev was well tolerated and delayed progression; therefore, it can be an alternative chemotherapy for refractory mCRC. We will report the data from final analysis at the meeting. Clinical trial information: 000009083.

57 Background: FOLFOXIRI plus bevacizumab (BEV) is regarded as the standard of care for selected patients (pts) with metastatic colorectal cancer (mCRC), despite the high incidence of neutropenia and diarrhea. The AXEPT phase III study showed that the modified capecitabine (CAP) + irinotecan (IRI) + BEV (CAPIRI+BEV) [CAP 1600 mg/m2, IRI 200 mg/m2, and BEV 7.5 mg/kg q3wk] treatment was non-inferior to FOLFIRI+BEV, with a lower incidence of hematologic toxicity. We hypothesized that the modified CAPIRI combined with oxaliplatin (OX) and BEV (CAPOXIRI+BEV) would be more feasible than FOLFOXIRI+BEV, without compromising efficacy. Methods: The QUATTRO-II study is an open-label, multicenter, randomized phase II study. In Step 1, the recommended doses (RD) of OX and IRI were investigated as a safety lead-in. In Step 2, pts are randomized to either the RD of CAPOXIRI+BEV or FOLFOXIRI+BEV. In Step 1, four dose levels of CAPOXIRI (fixed dose of CAP 1600 mg/m2 and BEV 7.5 mg/kg plus escalated or de-escalated doses of OX and IRI, q3wk) were investigated in a 3+3 manner. A dose level of ≤ 2/6 of dose-limiting toxicity (DLT) cases was expected as the RD. Results: A total of 9 pts (3 at Level 0, 6 at Level 1) were included in Step 1. The baseline characteristics were as follows: the median age was 62 years; 6 were male; 6 presented with a left-sided tumor; 8 had a performance status of 0; all wild type/ RAS mutant/ BRAF V600E mutant were 8/1/0; and UGT1A1 wild type/*6 single hetero/*28 single hetero were 7/0/2. In Level 0 (IRI 200 mg/m2, OX 100 mg/m2), one grade 4 neutropenia and one grade 3 anorexia were observed, but without DLT. In Level 1 (IRI 200 mg/m2, OX 130 mg/m2), two grade 4 neutropenia and one grade 3 colitis were observed, with 1 DLT (febrile neutropenia) case, fully recovered without G-CSF administration. No treatment-related deaths were observed. Although dose modifications were needed in 4 of the 6 pts, no further safety concerns related to treatment continuity were observed in the 2nd or subsequent cycles. Thus, we determined that the dose administered in Level 1 is the RD for Step 2. According to the preliminary efficacy results at 8 weeks after initiating study treatment, 6 pts achieved a partial response (2 in Level 0 and 4 in Level 1). Conclusions: The RD of CAPOXIRI+BEV was 200 mg/m2 IRI, 130 mg/m2 OX, 1600 mg/m2 CAP, and 7.5mg/kg BEV. The randomized phase II Step (Step 2) of QUATTRO-II is ongoing. Clinical trial information: NCT04097444.
