Abstract Background: This multicenter, randomized, phase III study compared B-R and CHOP-R as first-line treatment in patients (pts) with indolent lymphomas or MCL and was presented at ASH 2009, ASCO 2012, and published in The Lancet in 2013. The final published analysis at a median follow-up of 45 months demonstrated a significantly prolonged progression-free survival (PFS) in the B-R group, compared to the CHOP-R group (hazard ratio [HR] 0.58, 95% confidence interval [CI] 0.44–0.74; p<0.001). Median PFS was 69.5 vs. 31.2 months, respectively. In the current analysis, we present updated results for overall survival (OS), time-to-next-treatment (TTNT), and secondary malignancies (sNPL) with a median follow-up of 87 months. Methods: 549 pts with indolent lymphomas or MCL were randomized to receive B-R or CHOP-R for a maximum of 6 cycles. The primary endpoint was PFS; secondary endpoints included OS, TTNT, and sNPL. Results: 514 randomized pts were evaluable (261 B-R; 253 CHOP-R). Patient characteristics were well balanced between arms; median age was 64 years. Fewer pts treated initially with B-R needed second-line treatments due to disease progression compared to CHOP-R treated pts: 93 pts (36%) in the B-R group received salvage treatment compared with 140 pts (55%) in the CHOP-R group. Of those in the CHOP-R group, 69 pts (49%) received B-R as salvage. TTNT was significantly prolonged with B-R compared with CHOP-R (HR 0.53, 95% CI 0.40-0.68; p<0.001). Median TTNT was not yet reached in the B-R group vs. 42.3 months in the CHOP-R group. The difference in complete response (CR) rates (independent of treatment arms) between male (n=272, median age 63 years) and female (n=242, median age 64 years) pts was statistically significant: 28.6% for male pts versus 42.1% for female pts (p=0.0016). Female pts had a longer median TTNT compared to male pts (not yet reached vs. 52.2 months, respectively; HR 0.70, 95% CI 0.54-0.90; p=0.006). The achievement of a CR was associated with significantly prolonged OS, with an estimated 10-year survival rate of 72.6% for pts with a CR and 63.6% for pts with a partial response (p=0.006). The difference in OS between the treatment arms was not statistically significant, with 65 and 76 deaths in the B-R and CHOP-R arms, respectively. The estimated 10-year survival rates were 67.4% for B-R and 60.1% for CHOP-R (p=0.262). In pts with indolent lymphomas (total group without MCL), there was a trend toward longer survival for the B-R group compared with the CHOP-R group, with 43 deaths out of 215 pts (20.0%) in B-R and 58 deaths out of 205 pts (28.3%) in CHOP-R. The estimated 10-year survival rates for pts with indolent lymphomas were 71.9% for B-R and 61.5% for CHOP-R (HR 0.70, 95% CI 0.48-1.04; p=0.076). No difference in OS was found in the subgroup of pts with MCL (n=95) (HR 1.28, 95% CI 0.69-2.39; p=0.429). Twenty sNPL were observed in the B-R group compared with 23 in the CHOP-R group, with 1 hematological malignancy in each group (1 MDS in B-R, 1 AML in CHOP-R) to date. Updated sNPL results will be presented at the ASH meeting. Conclusions: In pts with previously untreated indolent lymphomas, and in elderly pts with MCL, B-R demonstrates a PFS and TTNT benefit over CHOP-R. OS for the entire group of patients was not significantly different while treatment with B-R resulted in a trend toward survival benefit in the group of pts with indolent lymphomas.

7501 Background: This multicenter, randomized, phase III study compared B-R and CHOP-R as first-line treatment in patients (pts) with indolent lymphomas or mantle cell lymphoma and was first published in The Lancet in 2013. The final analysis demonstrated a significantly prolonged progression-free survival (PFS) in the B-R group compared to the CHOP-R group, with a median PFS of 69.5 vs. 31.2 months, respectively. In the current analysis, we present updated results for overall survival (OS), time-to-next-treatment (TTNT), and secondary malignancies (sNPL) with a median follow-up of 113 months for patients with indolent lymphomas (excluding MCL). Methods: 447 pts with indolent lymphomas were randomized to receive B-R or CHOP-R for a maximum of 6 cycles. The primary endpoint was PFS; secondary endpoints included OS, TTNT, and sNPL. Results: Patient characteristics were well balanced between arms; median age was 64 years. The difference in OS between the two treatment arms was not statistically significant, with 60 deaths in the B-R group vs 68 deaths with CHOP-R (HR 0.82, 95% CI 0.58 – 1.15, p = 0.249). The estimated 10-year survival rates were 71% for B-R and 66% for CHOP-R. TTNT was significantly prolonged with B-R compared with CHOP-R (HR 0.52, 95% CI 0.38 – 0.69, p < 0.001). Median TTNT was not yet reached in the B-R group (95% CI 124.9 – n.y.r) vs. 56 months in the CHOP-R group (95% CI 39.1 – 82.0). Patients treated initially with B-R needed fewer second-line treatments due to disease progression compared to CHOP-R treated pts: 73 pts (34%) in the B-R group received salvage treatment compared with 106 pts (52%) in the CHOP-R group. For B-R pts, CHOP-R was used as second-line therapy 26 times (36%), whereas B-R was used for pts initially treated with CHOP-R 49 times (46%). 36 pts with sNPL were observed in the B-R group compared with 39 in the CHOP-R group, with 7 hematological malignancies in both groups to date. Conclusions: In pts with previously untreated indolent lymphomas, B-R demonstrates a PFS and TTNT benefit over CHOP-R. Clinical trial information: NCT00991211.

e21040 Background: The anti-angiogenic drug bevacizumab combined with chemotherapy has achieved positive results in previous studies. In particular, the median progression-free survival (PFS) for EGFR-negative patients was increased to 8.3 months in the BEYOND study. Unlike bevacizumab, anlotinib is a novel multitarget tyrosine kinase inhibitor and can be conveniently orally administered. In the phase III trial ALTER 0303, anlotinib significantly improved overall survival (OS) and PFS in advanced NSCLC patients. This exploratory study aims to establish the efficacy and safety of anlotinib in combination with pemetrexed and carboplatin as first-line treatment in advanced non-squamous NSCLC. Methods: This is a multi-center, single-arm clinical trial. Adults with treatment-naive, histologically confirmed stage IIIB-IV non-squamous NSCLC, ECOG 0-1, and without known sensitizing EGFR/ALK alterations are included. Patients received anlotinib (12 mg p.o., QD, d1 to 14, 21 days per cycle) combined with pemetrexed (500 mg/m2, iv, d15-21, Q3W) + carboplatin (AUC = 5, iv, d15-21, Q3W) for 4 cycles followed by anlotinib and pemetrexed maintenance until disease progression (PD). The primary endpoint was PFS. Secondary endpoints were OS, objective response rate (ORR), disease control rate (DCR) and safety. Results: Between Mar 2019 and Dec 2020, 40 patients were enrolled in six centers and 31 of them have received at least one tumor assessment. Median age was 62 (33, 75); 66.7% male, 11.1% brain metastasis. At data cutoff (Dec 31, 2020), patients were followed up for a median of 8.26 months. Median PFS was 10.5 months (95% CI: NE, NE); ORR was 67.7% (0 CR, 21 PR), DCR was 96.8% (0 CR, 21 PR, 9 SD) and median OS was NE. The most common Grade ≥ 3 AEs were hypertension 22.2%, neutropenia 19.44%, myelosuppression 11.1%, thrombocytopenia 8.33%, leukopenia 5.56%, hand-foot syndrome 5.56% and there were no Grade 5 toxicities. Conclusions: This study finds that anlotinib plus pemetrexed and carboplatin can significantly improve PFS and ORR compared to standard chemotherapy for treatment-naive non-squamous NSCLC patients. The combination was well tolerated, and the AEs were manageable. The follow-up time is not sufficient, and the OS outcomes need further evaluation. Clinical trial information: NCT03790228.

LBA2 Background: Gemcitabine-cisplatin (GP) chemotherapy is the standard 1st line treatment for locally advanced, recurrent or metastatic (r/m) NPC. Toripalimab, a humanized IgG4K monoclonal antibody specific for PD-1, provided durable responses in patients (pts) with r/m NPC as monotherapy in the ≥2nd line setting (POLARIS-02 study). The results of JUPITER-02, a randomized, placebo-controlled, double-blinded Phase III trial of toripalimab in combination with GP chemotherapy as first-line treatment for r/m NPC are summarized. Methods: Pts with advanced NPC with no prior chemotherapy in the r/m setting were randomized (1:1) to receive toripalimab 240 mg or placebo d1 in combination with gemcitabine 1000 mg/m2 d1, d8 and cisplatin 80 mg/m2 d1 every 3 weeks (Q3W) for up to 6 cycles, followed by monotherapy with toripalimab or placebo Q3W until disease progression, intolerable toxicity, or completion of 2 years of treatment. Stratification factors were ECOG PS (0 vs. 1) and extent of disease (recurrent vs. primary metastatic) at enrollment. Progression-free survival (PFS) and response were assessed by independent review committee (IRC) per RECIST v1.1. The primary endpoint was PFS by IRC in the ITT population. Secondary end points included ORR, DOR and OS. There was one prespecified interim analysis of PFS at 130 PFS events with a planned final analysis at 200 PFS events. Results: 289 pts were randomized: 146 to the toripalimab arm and 143 to the placebo arm. By May 30, 2020 as the interim analysis cutoff date, the median treatment duration was 39 weeks in the toripalimab arm and 36 weeks in the placebo arm. A significant improvement in PFS was detected for the toripalimab arm compared to the placebo arm (HR = 0.52 [95% CI: 0.36-0.74] two-sided p = 0.0003), with median PFS of 11.7 vs. 8.0 months. The 1-year PFS rates were 49% and 28% respectively. An improvement in PFS was observed across relevant subgroups, including all PD-L1 subgroups. The ORR was 77.4% vs. 66.4% (P = 0.033) and the median DOR was 10.0 vs. 5.7 months (HR = 0.50 [95% CI: 0.33-0.78]). As of Jan 15, 2021, OS was not mature, with 25 deaths in the toripalimab arm and 35 in the placebo arm (HR = 0.68 [95% CI: 0.41-1.14], P = 0.14). The incidence of Grade ≥3 adverse events (AEs) (89.0% vs 89.5%); AEs leading to discontinuation of toripalimab/placebo (7.5% vs 4.9%); and fatal AEs (2.7% vs 2.8%) were similar between two arms; however, immune-related (irAEs) (39.7% vs. 18.9%) and Grade ≥3 irAEs (7.5% vs. 0.7%) were more frequent in the toripalimab arm. Conclusions: The addition of toripalimab to GP chemotherapy as 1st-line treatment for pts with advanced NPC provided superior PFS and ORR and longer DOR than GP alone with a manageable safety profile. These results support the use of toripalimab with GP chemotherapy as the new standard care for this population. Clinical trial information: NCT03581786.

PurposeThis phase III study compared the safety and efficacy of the following three different irinotecan-containing regimens in the first-line treatment of metastatic colorectal cancer: irinotecan plus infusional fluorouracil (FU)/leucovorin (LV) (FOLFIRI), irinotecan plus bolus FU/LV (mIFL), and irinotecan plus oral capecitabine (CapeIRI).Patients and MethodsA total of 430 previously untreated metastatic colorectal cancer patients were randomly assigned to receive FOLFIRI (n = 144), mIFL (n = 141), or CapeIRI (n = 145). Patients were concurrently randomly assigned to a double-blind treatment with celecoxib or placebo. After a protocol amendment, an additional 117 patients were randomly assigned to either FOLFIRI plus bevacizumab (FOLFIRI+Bev; n = 57) or mILF plus bevacizumab (mIFL+Bev; n = 60), whereas the CapeIRI arm was discontinued. The primary study end point was progression-free survival (PFS), with secondary end points of overall survival (OS), response rate, and toxicity.ResultsMedian PFS was 7.6 months for FOLFIRI, 5.9 months for mIFL (P = .004 for the comparison with FOLFIRI), and 5.8 months for CapeIRI (P = .015). Median OS was 23.1 months for FOLFIRI, 17.6 months for mIFL (P = .09), and 18.9 months for CapeIRI (P = .27). CapeIRI was associated with higher rates of severe vomiting, diarrhea, and dehydration. After the amendment to add bevacizumab, the median survival time has not yet been reached for FOLFIRI+Bev and was 19.2 months for mIFL+Bev (P = .007). FOLFIRI+Bev was associated with a higher rate of ≥ grade 3 hypertension than mIFL+Bev.ConclusionFOLFIRI and FOLFIRI+Bev offered superior activity to their comparators and were comparably safe. An infusional schedule of FU should be the preferred irinotecan-based regimen in first-line metastatic colorectal cancer.

Abstract Design/Methods: We recently demonstrated in a phase III trial that the addition of rituximab to each of 8 cycles of CVP (R-CVP) chemotherapy significantly improves the clinical outcome of previously untreated patients with stage III/IV CD20 positive follicular NHL when compared to CVP alone (Marcus et al., Blood2005; 105: 1417–23). A multivariate Cox regression analysis of time to progression or death (TTP) showed a treatment benefit in all patient subgroups according to baseline risk factors, except for patients with a baseline hemoglobin level below normal. We now present an updated analysis of all major trial endpoints with 42 months follow-up (FU). Results: A total of 321 patients (median age 53 years) were recruited (159 CVP, 162 R-CVP). Approximately half of the patients had high-risk disease according to the Follicular Lymphoma International Prognostic Index (FLIPI, score 3–5). The median TTP was more than doubled for patients receiving R-CVP compared to CVP alone (33.6 months vs 14.5 months, p&lt;0.0001). Median time to new lymphoma treatment or death (TNLT) was 12.3 months in the CVP group and nearly quadrupled to 46.3 months in the R-CVP group (p&lt;0.0001). Superior response rates for R-CVP were confirmed (CR+CRu rate 41% vs 11%, p&lt;0.0001) with a median response duration (DR) of 13.5 months in the CVP arm versus 37.7 months in the R-CVP arm. Median disease free survival (DFS) in complete responders was 44.8 months for patients receiving R-CVP and 20.5 months in patients receiving CVP alone (p=0.0005). Thirty-five patients in the CVP arm and 23 patients in the R-CVP arm have died. Kaplan-Meier estimates of 3-year OS rates were 81% in the CVP arm and 89% in the R-CVP (p=0.07). Importantly, significantly more patients receiving CVP died due to lymphoma progression compared to patients receiving R-CVP (25 vs 12 deaths, p=0.02). Subgroup analysis for TTP, ORR, DR and OS according to risk factors at baseline are ongoing and will be presented. Conclusion: With longer FU, the combination of 8 cycles of rituximab with CVP chemotherapy continues to provide a major benefit as first line treatment for patients with advanced stage follicular NHL.

5024 Background: In a randomized phase III trial of patients (pts) with mRCC, sunitinib demonstrated a significant improvement in progression-free survival (PFS) and objective response rate (ORR) compared to IFN-a as first-line therapy (Proc ASCO 2006;24:2s [Abstract LBA3]). We present the most recent data from this trial and an analysis of prognostic factors. Methods: Untreated pts with clear-cell mRCC were randomized 1:1 to receive either sunitinib (repeated 6-week cycles of 50 mg/day orally for 4 weeks, followed by 2 weeks off treatment) or IFN-a (9 MU given subcutaneously three times weekly). The primary endpoint was PFS. Results: A total of 750 pts were randomized: 375 to sunitinib, 375 to IFN-a. The median duration of treatment is 11 months (range: <1–25) for sunitinib vs. 4 months (range: <1–22) for IFN-a. The updated ORR by investigator assessment is 44% (95% CI: 39, 49) for sunitinib vs. 11% (95% CI: 8, 15) for IFN-a (p <0.000001), including 4 complete responses for sunitinib and 2 for IFN-a. The median duration of response in the sunitinib group (n=165) is 12 months (95% CI: 10, 14) vs. 10 months (95% CI: 8, 17) in the IFN-a group (n=43). The median PFS is 11 months (95% CI: 10, 11) for sunitinib vs. 4 months (95% CI: 4, 5) for IFN-a. The median PFS for pts with 0 risk factors is 14 months (95% CI: 11, 16) for sunitinib vs. 8 months (95% CI: 7, 10) for IFN-a; 9 months (95% CI: 8, 11) vs. 4 months (95% CI: 4, 4), respectively, for pts with 1- 2 risk factors; 4 months (95% CI: 2, 10) vs. 1 month (95% CI: 1, 2), respectively, for pts with =3 risk factors. The sunitinib benefit in PFS extends across all MSKCC prognostic risk factor groups (HR=0.488; 95% CI: 0.406, 0.586). The baseline features that predict longer PFS (by investigator assessment) for the sunitinib group are hemoglobin =LLN (p=0.0043), corrected calcium =10 mg/dL (p=0.001), ECOG score of 0 (p=0.0005), number of metastatic sites 0 or 1 (p=0.0064), and time from diagnosis to treatment =1 yr (p=0.0002). Conclusions: Sunitinib is a reference standard for first-line treatment of mRCC, with significant improvement in PFS and ORR compared to IFN-a. The benefit of sunitinib extends across all subgroups of pts with mRCC. Previously defined MSKCC risk factors for mRCC predict longer PFS with sunitinib.

3574 Background: Infusional 5-FU/FA + oxaliplatin is a widely used schedule in the first-line treatment of mCRC. In the randomized phase II OPUS study, the addition of cetuximab to one such regimen (FOLFOX4) significantly improved response and progression-free survival (PFS) in patients (pts) with KRAS wild-type (wt) mCRC. However, in the randomized phase III COIN study, a benefit for the addition of cetuximab to first-line fluoropyrimidine (administered as either infusional 5-FU or capecitabine) + oxaliplatin was not confirmed in pts with KRAS wt tumors. Methods: A pooled study-based analysis of treatment outcome in pts with KRAS wt tumors from the OPUS study and COIN subgroup who received infusional 5-FU/FA + oxaliplatin (as the OxMdG regimen) was carried out using a random effects model. Outcome in the pooled analysis was considered in the context of other randomized studies investigating first-line chemotherapy regimens +/- cetuximab in pts with mCRC. Results: The pooled KRAS wt population included 179 pts from the OPUS study and 244 from the OxMdG subgroup of the COIN study. A benefit for the addition of cetuximab to infusional 5-FU/FA was suggested for response (odds ratio 1.87, 95% CI 1.07–3.28) and PFS (hazard ratio, HR 0.69, 95% CI 0.52–0.92) but overall survival (OS) did not show a statistically significant improvement (HR 0.90, 95% CI 0.73–1.11). These response and PFS data are similar to those of the KRAS wt population of the CRYSTAL study investigating infusional 5-FU/FA and irinotecan +/- cetuximab (response: odds ratio 2.07, 95% CI 1.52–2.83; PFS: HR 0.70, 95% CI 0.56–0.87) whereas the improvement in OS was statistically significant in that study (HR 0.80, 95% CI 0.67–0.95). Similar efficacy of FOLFOX + cetuximab and FOLFIRI + cetuximab in the first-line treatment of mCRC was also suggested by data from the randomized phase II CORE 1.2.001 and CELIM studies. Overall, the safety profile of infusional 5-FU/FA and oxaliplatin + cetuximab was found to be acceptable and manageable. Conclusions: The pooled analysis supports the use of cetuximab combined with infusional 5-FU/FA and oxaliplatin in the first-line treatment of KRAS wt mCRC.
