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.

TPS873 Background: Initial treatment of metastatic colorectal cancer (mCRC) involves a 5-fluorouracil based chemotherapy regimen, often in combination with anti-VEGF therapy. Upon disease progression, multiple studies have suggested a benefit for continued anti-VEGF therapy. There is increasing evidence that VEGF plays a role in cancer immune evasion. Targeting of inflammatory and immune checkpoints are attractive approaches to enhance the benefits of anti-VEGF therapy. The safety and activity of the anti-PD-L1 antibody atezolizumab with bevacizumab and with 5-FU, oxaliplatin, and bevacizumab have been recently reported; the combinations were well-tolerated and suggested clinical activity. Therefore, bevacizumab may increase the immunogenicity of colorectal cancers, and the combination of atezolizumab plus bevacizumab may be associated with clinically meaningful response rates and disease control. Furthermore, there may be candidate biomarkers that may identify those patients most likely to benefit from this combination. Methods: In this randomized, double-blind, multicenter, placebo-controlled phase II study, 135 patients with mCRC will be randomized 2:1 to receive capecitabine/bevacizumab/atezolizumab or capecitabine/bevacizumab/placebo. Patients with prior PD-L1/PD-1 therapy are ineligible. Primary and secondary efficacy will be conducted using ITT analysis. Safety analyses will include all randomized patients who receive at least one dose of study treatment. The primary objective is PFS. The secondary objectives are ORR, OS, safety, and tolerability. The primary comparison will be superiority of the active treatment for the PFS endpoint, atezolizumab versus placebo testing at 1-sided α = 0.1 (log rank test). A PFS hazard ratio of 0.618 (active treatment versus placebo) is detectable with 86% power (1 sided α = 0.1). No interim analyses for futility or efficacy will be conducted. A subset analysis will be performed in the microsatellite-high patients looking at potential differences in PFS and OS. Trial is active and currently recruiting patients. Clinical trial information: NCT02873195.

Purpose This double-blind, phase III study aimed to demonstrate that sunitinib plus FOLFIRI (fluorouracil, leucovorin, and irinotecan) was superior to placebo plus FOLFIRI in previously untreated metastatic colorectal cancer (mCRC). Patients and Methods Patients were randomly assigned to receive FOLFIRI and either sunitinib (37.5 mg per day) or placebo (4 weeks on treatment, followed by 2 weeks off [schedule 4/2]) until disease progression. The primary end point was progression-free survival (PFS). Secondary end points included overall survival, safety, and patient-reported outcomes. The correlation between genotype and clinical outcomes was also analyzed. Results In all, 768 patients were randomly assigned to sunitinib plus FOLFIRI (n = 386) or placebo plus FOLFIRI (n = 382). Following a second prespecified interim analysis, the study was stopped because of potential futility of sunitinib plus FOLFIRI. Final results are reported. The PFS hazard ratio was 1.095 (95% CI, 0.892 to 1.344; one-sided stratified log-rank P = .807), indicating a lack of superiority for sunitinib plus FOLFIRI. Median PFS for the sunitinib arm was 7.8 months (95% CI, 7.1 to 8.4 months) versus 8.4 months (95% CI, 7.6 to 9.2 months) for the placebo arm. Sunitinib plus FOLFIRI was associated with more grade ≥ 3 adverse events and laboratory abnormalities than placebo (especially diarrhea, stomatitis/oral syndromes, fatigue, hand-foot syndrome, neutropenia, thrombocytopenia, anemia, and febrile neutropenia). More deaths as a result of toxicity (12 v four) and significantly more dose delays, dose reductions, and treatment discontinuations occurred in the sunitinib arm. Conclusion Sunitinib 37.5 mg per day (schedule 4/2) plus FOLFIRI is not superior to FOLFIRI alone and has a poorer safety profile. This combination regimen is not recommended for previously untreated mCRC.

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.
