e20025 Background: Peripheral neuropathy (PN) is a common side effect associated with taxane treatment. In a phase III trial, nab-paclitaxel vs dacarbazine demonstrated a significant improvement in progression-free survival (4.8 vs 2.5 months; P = 0.044) and at the interim survival analysis, a trend toward prolonged overall survival (12.8 vs 10.7 months; P = 0.094) for the treatment of chemotherapy-naive patients with metastatic melanoma. Here we report on the PN profile of nab-paclitaxel in this phase III trial. Methods: Pts (median age, 63 years) with chemotherapy-naive stage IV melanoma (M1c stage, 65%; elevated LDH, 28%) and an ECOG performance status 0-1 were randomized to nab-paclitaxel 150 mg/m2 on days 1, 8, and 15 of a 28-day cycle (n = 264) or dacarbazine 1000 mg/m2on day 1 of each 21-day cycle (n = 265). PN events were defined based on the Standardized MedDRA Query (V 12.1, broad scope). Results: As expected, a higher proportion of pts receiving nab-paclitaxel vs dacarbazine had ≥ 1 treatment-related PN event (68% vs 8%; P < 0.001). Treatment-related grade ≥ 3 PN was more frequent with nab-paclitaxel vs dacarbazine (25% vs 0%; P < 0.001); 2 grade 4 events were reported in the nab-paclitaxel arm. Treatment-related grade ≥ 3 PN was 15% in pts who received up to the median of 3 cycles of nab-paclitaxel. PN led to dose reduction in 13% or discontinuation in 15% of nab-paclitaxel–treated pts. The median time to onset of grade ≥ 3 PN was 101 days (95% CI, 85 - 113). Most early-onset PN events, occurring within the first 3 cycles, were grade 1. Grade ≥ 2 PN events peaked by cycle 4 and subsided by cycle 9. Forty-one of the 64 (64%) pts with a grade ≥ 3 PN event had an improvement of ≥ 1 grade, with a median time to improvement of 28 days (95% CI, 17 - 64), and 33 of 64 (52%) pts had improved to grade 1 or better by a median of 67 days from onset (95% CI, 22- upper limit not estimable); 30 of 64 (47%) pts resumed treatment with nab-paclitaxel. Conclusions: In this phase III trial, grade ≥ 3 PN was the main treatment-related toxicity with nab-paclitaxel as observed in other studies. However, PN was rapidly reversible; a majority of pts had improvement of PN symptoms within 1 month and resumed treatment. Clinical trial information: NCT00864253.

9030 Background: Activating mutations of BRAF V600 can be found in 40%-50% of melanomas and are related to poor prognosis. In a phase 3 trial for the treatment of metastatic melanoma (MM) in chemotherapy-naive patients, nab-paclitaxel (nab-P) vs dacarbazine (DTIC) demonstrated a significant improvement in the primary endpoint of progression-free survival (PFS), assessed by independent radiological review (IRR), and a trend toward prolonged overall survival (OS) at the interim survival analysis. The study also explored the effect of BRAF status on the efficacy parameters. Methods: Chemotherapy-naive patients with stage IV melanoma (M1c stage 65%; elevated LDH 28%) and ECOG performance status 0-1 were randomized to nab-P 150 mg/m2 on days 1, 8, and 15 of a 28-day cycle (n = 264) or DTIC 1000 mg/m2 on day 1 of each 21-day cycle (n = 265) independent of BRAF status. Prespecified subgroup analyses of final PFS and interim OS in subgroups by BRAF status (V600E mutant, wild-type, or unknown) were performed. Results: BRAF mutation status was balanced between the treatment arms, with 36% and 38% of patients with known BRAF mutation status in the nab-P and DTIC arms, respectively. Patient characteristics were also balanced within BRAF subgroups. As shown in the Table, advantage in the nab-P arm vs DTIC arm was observed for both PFS and interim OS regardless of BRAFmutation status. Poststudy BRAF inhibitor treatment was also balanced. Conclusions: In this phase III trial, treatment effect was independent of BRAF mutation status, benefiting all patients who received nab-P vs DTIC. Therefore nab-P should be considered in the armamentarium for all chemotherapy-naive patients with MM. Clinical trial information: NCT00864253. [Table: see text]

7565 Background: Standard first-line chemotherapy for elderly NSCLC pts has been considered as a monotherapy with vinorelbine or gemcitabine globally. However, we have demonstrated the high efficacy of CP for elderly pts in our previous trial (Ann Oncol 2010). Meanwhile, D has been considered as an alternative option for this population in Japan according to the result of WJTOG9904 (JCO 2006). Thus we compared the two regimens to select the proper candidate for future phase III trial. Methods: Eligible pts were aged 70 years or older with newly diagnosed stage IIIB/IV NSCLC; ECOG performance status 0-1; adequate organ function; written informed consent. Pts were randomized to receive carboplatin (AUC 6) on day 1 and paclitaxel (70mg/m2 on day 1, 8, and 15) every 4 weeks or D (60mg/m2 on day 1) every 3 weeks. The primary endpoint was overall response rate (ORR), and secondary endpoints were progression-free survival (PFS), overall survival, and toxicity profile. Assuming that ORR of 40% would be potential usefulness while ORR of 20% would be the lower limit of interest, 40 pts in each arm were required if expect 10% loss to follow up. Results: Between July 2006 and September 2010, 84 pts were enrolled and 41 pts in CP arm and 42 pts in D arm were eligible (median age, 76 years; 75% male; 72% stage IV). Median treatment cycle was 4 in each arm (CP, range 1-6; D, range 1-8). ORRs were 51% (95%CI: 36-66%) and 26% (95%CI: 12-39%) in the CP and D arm, respectively. With a median follow-up of 18.4 months, median PFS were 6.5 and 3.9 months in the CP and D arm, respectively (Logrank, P=0.0027). Grade 3 or severer toxicities were as follows: neutropenia (CP, 56% and D, 79%), anemia (CP, 15% and D, 7%), thrombocytopenia (CP, 10% and D, 0%), infection (CP, 20% and D, 25%). One treatment-related death due to neutropenia, pneumonia, and lethal arrhythmia occurred in D arm but none in CP arm. Conclusions: The platinum doublet CP achieved higher activity with an acceptable toxicity profile for elderly pts with advanced NSCLC compared to monotherapy with D. The superiority of CP to the monotherapy in this trial is consistent with results of recent IFCT-0501 trial (Lancet 2011).

9000 Background: In the randomized phase 3 CheckMate 9LA trial (NCT03215706), first-line NIVO + IPI combined with 2 cycles of chemo significantly improved overall survival (OS), progression-free survival (PFS), and objective response rate (ORR) vs chemo alone (4 cycles). Clinical benefit was observed regardless of programmed death ligand 1 (PD-L1) expression level and histology. Here we report data with 2 years’ minimum follow-up from this study. Methods: Adult patients (pts) with stage IV / recurrent NSCLC, ECOG performance status ≤ 1, and no known sensitizing EGFR/ALK alterations were stratified by PD-L1 (< 1% vs ≥ 1%), sex, and histology (squamous vs non-squamous) and were randomized 1:1 to NIVO 360 mg Q3W + IPI 1 mg/kg Q6W + chemo (2 cycles; n = 361) or chemo alone (4 cycles; n = 358). Pts with non-squamous NSCLC in the chemo-alone arm could receive pemetrexed maintenance. The primary endpoint was OS. Secondary endpoints included PFS and ORR by blinded independent central review, and efficacy by different PD-L1 levels. Safety was exploratory. Results: At a minimum follow-up of 24.4 months for OS (database lock: Feb 18, 2021), pts treated with NIVO + IPI + chemo continued to derive OS benefit vs chemo, with a median OS of 15.8 months vs 11.0 months, respectively (HR, 0.72 [95% CI, 0.61–0.86]); 2-year OS rates were 38% vs 26%. Median PFS with NIVO + IPI + chemo vs chemo was 6.7 months vs 5.3 months (HR, 0.67 [95% CI, 0.56–0.79]); 8% and 37% of pts who had disease progression received subsequent immunotherapy, respectively. ORR was 38% with NIVO + IPI + chemo vs 25% with chemo. Similar clinical benefit with NIVO + IPI + chemo vs chemo was observed in all randomized pts and across the majority of subgroups, including by PD-L1 expression level (Table) or histology. Any grade and grade 3–4 treatment-related adverse events were reported in 92% and 48% of pts in the NIVO + IPI + chemo arm vs 88% and 38% in the chemo arm, respectively. Conclusion: With 2 years’ minimum follow-up, first-line NIVO + IPI + chemo demonstrated durable survival and benefit versus chemo in pts with advanced NSCLC; no new safety signals were identified. Clinical trial information: NCT03215706. [Table: see text]

PurposeThis phase III trial compared the efficacy and safety of gemcitabine (Gem) plus capecitabine (GemCap) versus single-agent Gem in advanced/metastatic pancreatic cancer.Patients and MethodsPatients were randomly assigned to receive GemCap (oral capecitabine 650 mg/m2twice daily on days 1 to 14 plus Gem 1,000 mg/m2by 30-minute infusion on days 1 and 8 every 3 weeks) or Gem (1,000 mg/m2by 30-minute infusion weekly for 7 weeks, followed by a 1-week break, and then weekly for 3 weeks every 4 weeks). Patients were stratified according to center, Karnofsky performance score (KPS), presence of pain, and disease extent.ResultsA total of 319 patients were enrolled between June 2001 and June 2004. Median overall survival (OS) time, the primary end point, was 8.4 and 7.2 months in the GemCap and Gem arms, respectively (P = .234). Post hoc analysis in patients with good KPS (score of 90 to 100) showed a significant prolongation of median OS time in the GemCap arm compared with the Gem arm (10.1 v 7.4 months, respectively; P = .014). The overall frequency of grade 3 or 4 adverse events was similar in each arm. Neutropenia was the most frequent grade 3 or 4 adverse event in both arms.ConclusionGemCap failed to improve OS at a statistically significant level compared with standard Gem treatment. The safety of GemCap and Gem was similar. In the subgroup of patients with good performance status, median OS was improved significantly. GemCap is a practical regimen that may be considered as an alternative to single-agent Gem for the treatment of advanced/metastatic pancreatic cancer patients with a good performance status.

356154 Background: Combinations of immune checkpoint inhibitors (CPI) blocking PD-1 and CTLA-4 or BRAF/MEK inhibitors have both shown significant antitumor efficacy and overall survival (OS) benefit in patients (pts) with BRAFV600-mutant metastatic melanoma (MM), leading to broad regulatory approval. Little prospective data exists to guide the choice of one over the other as initial therapy or the preferred treatment sequence in this population. The DREAMseq Trial was designed to compare the efficacy and toxicity of the sequence of nivolumab/ipilimumab (N/I) followed by dabrafenib/trametinib (D/T) to the converse sequence. Methods: Eligible pts with treatment-naive BRAFV600-mutant MM were stratified by ECOG Performance Status (PS) 0 or 1 and LDH level and randomized 1:1 to receive Step 1 with either N/I (Arm A) or D/T (Arm B) and at disease progression (PD) were enrolled in Step 2 receiving the alternate therapy, D/T (Arm C) or N/I (Arm D), respectively. Pts received N (1mg/kg)/I (3 mg/kg) q3 wks x 4 doses followed by N 240 IV q2 wks for up to 72 wks (Arms A and D) or D 150 mg po BID and T 2 mg po qD until PD (Arms B and C). In 2019, investigators were given the option to use alternate induction dosing of N (3mg/kg)/I (1 mg/kg) q3 wks x 4 doses for Arms A and D. Cycles were every 6 wks and imaging was obtained at baseline and q12 wks on each arm. Primary endpoint was 2-year OS. At the 4th Interim Analysis with 59% of pts being 2 yrs from enrollment, the DSMC and NCI CTEP recommended halting accrual and releasing the data. Results: Beginning 7/2015, 265 out of a proposed 300 pts were enrolled (133 Arm A and 132 Arm B). Median age was 61 (25-85) and 63% were male. Demographics for Arm A and B were balanced with 67% PS 0 and 60% with normal LDH. As of 7/16/21, at a median follow-up of 27.7 mos, 27 pts had switched to Arm C and 46 to Arm D. Overall Grade 3+ toxicity was 60% in Arm A and 52% in Arm B. Grade 5 treatment-related AEs included 2 on Arm A and 1 on Arm C. ORR to date is: Arm A 46% (52/113), Arm B 43% (49/114), Arm C 48% (11/23) and Arm D 30% (8/27). 37/42 assessed pts in Arm A and 19/37 in Arm B remain in response. Median DOR: Arm A- Not reached; Arm B-12.7 mos (95% CI: 8.2, -) (p <0.001). There were 100 deaths (Arm A to C- 38/Arm B to D- 62). 2-yr OS rate for those starting with Arm A was 72% (95% CI: 62-81%) and for Arm B 52% (95% CI: 42-62%) (log-rank p= 0.0095). PFS showed a trend in favor of Arm A (log-rank p=0.054). Both the PFS and OS curves show a biphasic pattern with Arm B being above Arm A until 6 and 10 mos, respectively. For the 115 pts with documented progression on Step 1 (Arm A-44/Arm B-71), 60 (52%) had registered for Step 2. The principal reason for not enrolling on Step 2 was death from PD within 6 mos (Arm A:15/23; Arm B: 25/32). Conclusions: For pts with advanced BRAFV600-mutant MM, the treatment sequence beginning with the CPI combination of N/I resulted in superior OS, which became evident at 10 mos, with longer Step 1 DOR and more ongoing responses than the treatment sequence beginning with D/T. Clinical trial information: NCT02224781.

Purpose We hypothesized that the addition of gefitinib, an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, to docetaxel would enhance therapeutic efficacy in squamous cell carcinoma of the head and neck (SCCHN). Patients and Methods Patients with recurrent or metastatic SCCHN with Eastern Cooperative Oncology Group (ECOG) performance status of 2, or patients with ECOG performance status of 0 to 2 but were previously treated with chemotherapy, were randomly assigned to receive weekly docetaxel plus either placebo (arm A) or gefitinib 250 mg/d, orally (arm B) until disease progression. At the time of progression, patients in the placebo arm could receive single-agent gefitinib. EGFR, c-MET, and KRAS mutations and polymorphisms in drug metabolizing enzymes and transporters were evaluated by pyrosequencing. Results Two hundred seventy patients were enrolled before the study was closed early at interim analysis (arm A, n = 136; arm B, n = 134). Median overall survival was 6.0 months in arm A versus 7.3 months in arm B (hazard ratio, 0.93; 95% CI, 0.72 to 1.21; P = .60). An unplanned subset analysis showed that gefitinib improved survival in patients younger than 65 years (median 7.6 v 5.2 months; P = .04). Also, there was a trend for improved survival in patients with c-MET wild-type (5.7 v 3.6 months; P = .09) regardless of treatment. Grade 3/4 toxicities were comparable between the two arms except that grade 3/4 diarrhea was more common with docetaxel/gefitinib. Of 18 eligible patients who received gefitinib after disease progression in arm A, one patient had a partial response. Conclusion The addition of gefitinib to docetaxel was well tolerated but did not improve outcomes in poor prognosis but otherwise unselected patients with SCCHN.

Abstract Background: We previously reported substantial activity with single-agent bortezomib (VELCADE®; Vc) in patients (pts) with relapsed or refractory MCL in the PINNACLE study (JCO2006;24:4867–74), which resulted in approval of Vc for MCL pts following ≥1 prior therapy. All pts have now completed treatment. Here we report updated time-to-event data in all pts, and by response category, with extended follow-up. Methods: 155 pts (median age 65 yrs; 55%/41%/4% with 1/2/≥3 prior therapies; 77% Stage IV MCL; 55% positive bone marrow) received Vc 1.3 mg/m2 on days 1, 4, 8, and 11 of 21-day cycles; of these, 141 were response-evaluable. Response and progression were determined by modified International Workshop Response Criteria using independent radiology review. Results: After a median follow-up of 26.4 mo, 55 pts (35%) remained in follow-up; 93 (60%) had died, 2 (1%) had withdrawn consent, and 5 (3%) were lost to follow-up. Pts received a median of 4 treatment cycles (range 1–21; 8 in responding pts). Median time to first response was 1.3 months. Median duration of response (DOR) was 9.2 mo in all responders and has not been reached in pts achieving CR/CRu. Median time to progression (TTP), time to next therapy (TTNT; first Vc dose to start of next therapy), and overall survival (OS) are shown in the table for all pts and by response. Survival rate at 12-mo was 69% overall and 91% in responding pts. In pts refractory to their last therapy (no response or response with TTP <6 mo; n=58), median DOR was 5.9 mo, median TTP was 3.9 mo, median TTNT was 4.6 mo, and median survival was 17.3 mo. Safety profile was similar to previously reported; most common grade ≥3 AEs were peripheral neuropathy (13%), fatigue (12%), and thrombocytopenia (11%). The most common AE resulting in Vc discontinuation was peripheral neuropathy (10%). Twelve (8%) pts died on-study, including 5 (3%) considered related to Vc. Conclusions: Vc provides durable responses plus prolonged time off-therapy and survival in responding pts, suggesting substantial clinical benefit in relapsed/refractory MCL.

7033 Background: Carboplatin/vinorelbine (CV) and carboplatin/gemcitabine (CG) are novel 2-drug combinations in the treatment of NSCLC. In a randomized national multicenter phase III study in stage IIIB and IV patients (pts), we compared these regimens with respect to efficacy, toxicity and quality of life (QoL). Methods: Chemonaive pts with histologically or cytologically proven NSCLC, stage IIIB or IV and ECOG performance status (PS) 0–2 were eligible. There was no upper age limit. Pts received vinorelbine 25 mg/m2 or gemcitabine 1000 mg/m2, both administered on day 1 and 8, in combination with carboplatin (Chatelut AUC 4) at day 1. Three courses were administered in 3-week cycles. QoL questionnaires were completed at baseline, before each cycle and then every 8 weeks up to one year. Primary endpoints were survival and QoL and secondary endpoints toxicity and time to progression (TTP). Stratification was done for age, stage and PS, and the planned sample size per arm was minimum 200. The analyses were performed on an intention-to-treat basis Results: From Oct 2003 through Dec 2004, 433 pts from 33 institutions were randomized to CV (n=218) or CG (n=215). Follow-up was minimum one year. There was no difference in overall survival between the two arms (p=0.89). Median survival was 7.3 vs. 6.5 months and 1-year survival 28% and 31% in the CV and CG arm respectively. TTP was significantly longer in the CG arm (p=0.006) with median TTP 4.2 vs. 3.9 months. There was significantly more grade 3–4 anemia and thrombocytopenia in the CG arm (p<0.001) and more grade 3–4 leucopenia in the CV arm (p= 0.001). More pts in the CG arm needed transfusions of blood (p=0.003) or platelets (p=0.001). There was no difference between the arms with respect to neutropenic infections (p=0.87). QoL data are still being analyzed and will be presented at ASCO. Conclusions: Overall survival was similar in the two treatment arms. In the CG arm, the median TTP was longer, but grade 3–4 toxicity requiring interventions, was more frequent when compared to the VC arm. No significant financial relationships to disclose.

1057 Background: Interference with both HER2 and epidermal growth factor (EGFR) dependent pathways may improve therapeutic efficacy of docetaxel (doc) in pts with HER2 overexpressing (+) BC. Methods: Patients (pts) without prior chemotherapy (Rx) exposure for stage IV HER-2 + BC were enrolled. Prior hormonal or adjuvant Rx inclusive of taxane or trastuzumab (tras) were allowed. A left ventricular ejection fraction of > 45% and ECOG performance status of ≥ 2 were required. Pts were to receive doc 75 m2, tras every 3 weeks, and gefitinib (gef) 250 mg daily. BC samples from 12 pts were analyzed by FISH for HER2 and EGFR amplification (amp), and topoisomerase II (topo II) amp or loss. IHC was to be performed to examine p-Src, p-STAT3, Ki67 and survivin expression. Results: The median age was 49 (range, 34–67) and ECOG performance status 0.5 (0–1). The first 9 patients received gef 250 mg daily; 2 pts received dox 75 mg/m2 and developed grade 3 febrile neutropenia (neu), hence, additional pts received doc at 60 mg/m2: 3 more episodes of grade 3 neu were seen. Gef was held due to grade 3 dermatitis (2 pts) and diarrhea (2 pts). Pts received a median of 6 cycles (3–10). Gef schedule then was changed, and was prescribed on days 2–14, only. Three of the next 9 pts experienced grades 3 or 4 neu, and we observed 3 cases of grade 3 gastrointestinal toxicities; pts were able to receive 11 + (range; 5–25+) cycles on this schedule (p<0.04). There were 4 complete (CR)and 6 partial R (23 % CR, 59 % overall R), and 3 pts had stable disease (SD; all R and SD confirmed); 3 pts progressed at 4, 4, and 5 mos, 1 pt was inevaluable. The median time to progression is 12 + mos. Samples from 3 pts revealed topo II amplification and one pt sample showed loss of one topo II allele; none were amplified for EGFR. Outcome will be correlated with IHC defined signal trasduction status and proliferation rates. Conclusions: The combination of doc, tras, and short course of gef is feasible, with encouraging R and SD rates and time to progression. Further exploration of simultaneous blockage of multiple signal transduction pathways is indicated in combination with chemoRx. Supported by NCI CA33572 and by a grant from AstraZeneca.

8514 Background: Ipilimumab (Ipi) alters the immune system balance by inhibiting the suppression of T-cell function. In two phase III trials, Ipi has shown an overall survival benefit alone and in combination with dacarbazine in previously treated and treatment-naïve patients (pts) with metastatic melanoma (MM), respectively. We performed a single-institution, phase II clinical trial of Ipi plus temozolomide (Tem) in pts with MM. Methods: Pts between the ages of 18 and 75 with previously untreated unresectable stage III or stage IV MM and an ECOG Performance Status of 0 to 1 were enrolled in a phase II trial of Ipi plus Tem. Induction phase consisted of Ipi 10mg/kg intravenous on Day 1 and oral Tem 200 mg/m2 on Days 1 – 4 every 3 weeks for 4 doses. Maintenance consisted of Ipi 10 mg/kg intravenous on Day 1 starting week 12 and repeated every 12 weeks and oral Tem 200 mg/m2 on Days 1 – 5 starting week 12 and repeated every 4 weeks until disease progression or unacceptable toxicity occurred. The primary endpoint was progression-free survival (PFS) rate at 6 months. Responses were evaluated using immune-related response criteria. Results: Sixty-four pts were enrolled and received at least one dose of study drug. All pts were included in the analysis. With a median follow-up of 8.5 months, the PFS rate at 6 months was 43%, exceeding the proposed rate of 30%, and the median PFS was 5.1 months. There were 10 (15.6%) confirmed complete responses and 8 (12.5%) confirmed partial responses. At the time of this analysis, median overall survival has not been reached. Immune-related adverse events (irAEs) were experienced by 88% of pts, most commonly pruritus (88%), rash (83%), diarrhea (56%), transaminitis (45%), and colitis (11%). Grade 3/4 irAEs seen in more than one patient were skin rash (11%), diarrhea (9%), pruritus (6%), and transaminitis (5%). Constipation occurred in 70% of pts and was the most common gastrointestinal (GI) toxicity. There were no GI perforations or deaths on study due to treatment. Conclusions: At a median follow-up of 8.5 months, the best overall response rate in this study is 28%. Ipi at 10 mg/kg in combination with Tem given in an induction followed by maintenance fashion is safe, well-tolerated, and efficacious in MM.
