7591 Background: Erlotinib is associated with a survival benefit over placebo for pts with advanced NSCLC who had received 1–2 prior regimens. Its role as initial therapy in clinically defined subgroups or in pts prospectively tested for EGFR mutations is less clear. Methods: Chemotherapy-naive women with adenocarcinoma, stage IIIB/IV, PS 0–1, who had formerly or never smoked, were enrolled and treated with erlotinib 150 mg PO daily, until the time of disease progression or unacceptable toxicity. Response rate was the primary endpoint. Secondary endpoints included overall survival, progression-free survival and toxicity. Tumor tissue adequate for genomic analysis was mandated and prospectively collected for determination of EGFR and KRAS mutations by direct sequencing. Results: From 11/04 to 10/06, 40 women were treated. Demographics: median age 65 yrs (range 36–87); 38 white, 1 black, 1 Asian; 30% PS 0, 70% PS 1; 20% BAC or adenoCA w/ predominant BAC features, 80% adenoCA w/o BAC features; smoking status: 63% former, 37% never. Toxicity: Rash (95%; 30% grade 3) and diarrhea (73%; 10% grade 3) were the most common toxicities. 50% of pts developed toxicity of grade 3 or greater. 5 pts were discontinued due to toxicity, with 2 deaths that were possibly treatment-related: 1 DIC, 1 hepatic failure. There were also two pts with PE (one fatal). Response: CR 0, PR 12 (30%), SD 11 (28%), and PD 10 (25%), 7 not evaluable. To date, 27 patients have progressed, with 14 deaths. Median PFS was 5.6 months; median overall survival has not yet been reached and exceeds 23 months. Of 32 patients sequenced for EGFR to date, there were 9 exon 19 deletions, 3 L858R mutations, and 1 exon 20 insertion. For the 12 pts prospectively determined to have classic EGFR mutations, RR was 75% (9 PR, 2 SD, 1 not evaluable). Of 15 pts w/ wild-type EGFR, only 1 response (7%) was achieved. The pt w/ the exon 20 insertion developed PD. Of 28 pts evaluated to date for KRAS, 6 KRAS mutations were found, w/ no responses in this group (2 PD, 4 SD). Conclusions: Preliminary results suggest that first-line erlotinib monotherapy may be a useful treatment strategy for women with adenocarcinoma and a limited smoking history. Response rate is particularly impressive for those subjects prospectively found to have an EGFR mutation, and poor for those with KRAS mutations. No significant financial relationships to disclose.

PURPOSE Melphalan flufenamide (melflufen) is a first-in-class peptide-drug conjugate that targets aminopeptidases and rapidly and selectively releases alkylating agents into tumor cells. The phase II HORIZON trial evaluated the efficacy of melflufen plus dexamethasone in relapsed and refractory multiple myeloma (RRMM), a population with an important unmet medical need. PATIENTS AND METHODS Patients with RRMM refractory to pomalidomide and/or an anti-CD38 monoclonal antibody received melflufen 40 mg intravenously on day 1 of each 28-day cycle plus once weekly oral dexamethasone at a dose of 40 mg (20 mg in patients older than 75 years). The primary end point was overall response rate (partial response or better) assessed by the investigator and confirmed by independent review. Secondary end points included duration of response, progression-free survival, overall survival, and safety. The primary analysis is complete with long-term follow-up ongoing. RESULTS Of 157 patients (median age 65 years; median five prior lines of therapy) enrolled and treated, 119 patients (76%) had triple-class–refractory disease, 55 (35%) had extramedullary disease, and 92 (59%) were refractory to previous alkylator therapy. The overall response rate was 29% in the all-treated population, with 26% in the triple-class–refractory population. In the all-treated population, median duration of response was 5.5 months, median progression-free survival was 4.2 months, and median overall survival was 11.6 months at a median follow-up of 14 months. Grade ≥ 3 treatment-emergent adverse events occurred in 96% of patients, most commonly neutropenia (79%), thrombocytopenia (76%), and anemia (43%). Pneumonia (10%) was the most common grade 3/4 nonhematologic event. Thrombocytopenia and bleeding (both grade 3/4 but fully reversible) occurred concomitantly in four patients. GI events, reported in 97 patients (62%), were predominantly grade 1/2 (93%); none were grade 4. CONCLUSION Melflufen plus dexamethasone showed clinically meaningful efficacy and a manageable safety profile in patients with heavily pretreated RRMM, including those with triple-class–refractory and extramedullary disease.

Purpose Metastatic pancreatic ductal adenocarcinoma is characterized by excessive hyaluronan (HA) accumulation in the tumor microenvironment, elevating interstitial pressure and impairing perfusion. Preclinical studies demonstrated pegvorhyaluronidase alfa (PEGPH20) degrades HA, thereby increasing drug delivery. Patients and Methods Patients with previously untreated metastatic pancreatic ductal adenocarcinoma were randomly assigned to treatment with PEGPH20 plus nab-paclitaxel/gemcitabine (PAG) or nab-paclitaxel/gemcitabine (AG). Tumor HA levels were measured retrospectively using a novel affinity histochemistry assay. Primary end points were progression-free survival (PFS; overall) and thromboembolic (TE) event rate. Secondary end points included overall survival, PFS by HA level, and objective response rate. An early imbalance in TE events in the PAG arm led to a clinical hold; thereafter, patients with TE events were excluded and enoxaparin prophylaxis was initiated. Results A total of 279 patients were randomly assigned; 246 had HA data; 231 were evaluable for efficacy; 84 (34%) had HA-high tumors (ie, extracellular matrix HA staining ≥ 50% of tumor surface at any intensity). PFS was significantly improved with PAG treatment overall (hazard ratio [HR], 0.73; 95% CI, 0.53 to 1.00; P = .049) and for patients with HA-high tumors (HR, 0.51; 95% CI, 0.26 to 1.00; P = .048). In patients with HA-high tumors (PAG v AG), the objective response rate was 45% versus 31%, and median overall survival was 11.5 versus 8.5 months (HR, 0.96; 95% CI, 0.57 to 1.61). The most common treatment-related grade 3/4 adverse events with significant differences between arms (PAG v AG) included muscle spasms (13% v 1%), neutropenia (29% v 18%), and myalgia (5% v 0%). TE events were comparable after enoxaparin initiation (14% PAG v 10% AG). Conclusion This study met its primary end points of PFS and TE event rate. The largest improvement in PFS was observed in patients with HA-high tumors who received PAG. A similar TE event rate was observed between the treatment groups in stage 2 of the trial.

ObjectivesThe purpose of this study was to assess the clinical activity and toxicity of weekly topotecan in a large cohort of epithelial ovarian (EOC), primary peritoneal (PPC), and tubal cancer patients.MethodsRecords of patients with recurrent EOC, PPC, and tubal cancer who were treated with weekly topotecan (4.0 mg/m2 on days 1, 8, and 15 on a 28-day cycle) after failure of more than 1 prior regimen were retrospectively reviewed in 8 centers in Israel.ResultsTwo hundred four patients were evaluated for efficacy and toxicity. Median age was 62 years (range, 27–89 years); 121 (59.3%) were platinum sensitive. Patients were exposed to a median of 2 previous lines (range, 1–9), and 48.5% received only 1 prior chemotherapy regimen. Median follow-up was 15.5 months (range, 2.5–112 months). Overall response rate was 26.5%, of which 11 patients (5.4%) had complete response, and 43 patients (21.1%) had partial response. Clinical benefit rate (complete response + partial response + stable disease) was 65.7%. Median progression-free survival was 4.0 months (95% confidence interval [CI], 3.5–4.5 months). There was no significant difference between platinum-sensitive and platinum-resistant patients regarding response rate or progression-free survival. Median overall survival from disease diagnosis was 45.0 months (95% CI, 40.04–49.6 months) and 16.0 months (95% CI, 12.3–19.7 months) from initiation of topotecan therapy. Overall survival was significantly different between patients with platinum-sensitive and platinum-resistant disease (19.9 vs 10.8 months, respectively, P = 0.003; 95% CI, 8.1–16.3 months). Multivariate analysis showed that only platinum sensitivity and topotecan line were associated with overall survival. Weekly topotecan was well tolerated—with only 16.7% of patients experiencing grade 3 to 4 hematologic toxicities. There were no other grade 4 toxicities, and only 6.9% grade 3 toxicities.ConclusionsIn this large cohort of recurrent EOC, PPC, and tubal cancer, weekly topotecan was well tolerated with good clinical benefit rate, comparable to previous studies.

Purpose Bortezomib-melphalan-prednisone (VMP) has improved overall survival in multiple myeloma. This randomized trial compared VMP plus thalidomide (VMPT) induction followed by bortezomib-thalidomide maintenance (VMPT-VT) with VMP in patients with newly diagnosed multiple myeloma. Patients and Methods We randomly assigned 511 patients who were not eligible for transplantation to receive VMPT-VT (nine 5-week cycles of VMPT followed by 2 years of VT maintenance) or VMP (nine 5-week cycles without maintenance). Results In the initial analysis with a median follow-up of 23 months, VMPT-VT improved complete response rate from 24% to 38% and 3-year progression-free-survival (PFS) from 41% to 56% compared with VMP. In this analysis, median follow-up was 54 months. The median PFS was significantly longer with VMPT-VT (35.3 months) than with VMP (24.8 months; hazard ratio [HR], 0.58; P < .001). The time to next therapy was 46.6 months in the VMPT-VT group and 27.8 months in the VMP group (HR, 0.52; P < .001). The 5-year overall survival (OS) was greater with VMPT-VT (61%) than with VMP (51%; HR, 0.70; P = .01). Survival from relapse was identical in both groups (HR, 0.92; P = .63). In the VMPT-VT group, the most frequent grade 3 to 4 adverse events included neutropenia (38%), thrombocytopenia (22%), peripheral neuropathy (11%), and cardiologic events (11%). All of these, except for thrombocytopenia, were significantly more frequent in the VMPT-VT patients. Conclusion Bortezomib and thalidomide significantly improved OS in multiple myeloma patients not eligible for transplantation.

Abstract Neutropenia is a common side effect associated with nab-paclitaxel gemcitabine (Nab-Gem) therapy. We retrospectively investigated the association between neutropenia induced by first-line Nab-Gem and survival in metastatic pancreatic carcinoma patients. Metastatic pancreatic patients treated with first-line Nab-Gem were included in this retrospective analysis. Neutropenia was categorized using the National Cancer Institute Common Toxicity Criteria scale. Outcome measures were overall survival (OS), progression-free survival (PFS) and response rate. 115 patients were analyzed. Median PFS was 7 months (95% CI 5–8) for patients with grade ≥ 3 neutropenia and 6 months (95% CI 5–6) for patients with grade < 3 neutropenia [p = 0.08; hazard ratio (HR 0.68)]. Median OS was 13 months (95% CI 10–18) for patients with grade ≥ 3 neutropenia and 10 months (95% CI 8–13) for patients with grade < 3 neutropenia (p = 0.04; HR 0.44). In multivariate analysis, the occurrence of grade ≥ 3 neutropenia showed a statistically significant association with OS (HR 0.62; 95% CI 0.09–0.86; p = 0.05). Nab-Gem-induced neutropenia is associated with longer survival in metastatic pancreatic cancer patients.

18177 Background: The efficacy and safety of a combined regimen of topotecan and etoposide was tested in patients with relapsed or refractory small-cell lung cancer. Methods: From October 2003 to May 2005, 23 patients who have failed to the previous irinotecan and platinum chemotherapy received intravenous topotecan 1mg/m2 (day 1–5) followed by intravenous etoposide 80mg/m2 (day 1–3). Treatment was repeated every 21 days for a maximum of 6 cycles. Results: Twelve patients were refractory to first-line chemotherapy. Seventeen patients (73.9%) were male and the median age was 63 years. ECOG performance status was 0–1 in 13 (56.5%) patients. The median cycles of chemotherapy was 3. Twenty one patients were assessable for response evaluation. The overall response rate was 17.4% (0 CR, 4 PR, 7 SD, 10 PD) under the intent-to-treat analysis. After a median follow- up of 20.8 months, median progression free survival was 4.7 months and median overall survival was 9.5 months. The estimated 1-year survival rate was 38.7%. In sensitive relapsed patients, 2 achieved tumor response and median progression free survival and overall survival were 5.5 months and 14.5 months. All patients were assessable for toxicity and major toxicities were myelosuppression. Grade 3/4 neutropenia and thrombocytopenia occurred in 18 (78.3%) and 12 (52.2%) patients, respectively. Grade 3/4 febrile neutropenia occurred in 2 patients (8.7 %) and infection in 3 patients (13.0%). There was one treatment-related death due to pneumonia. Conclusions: This salvage regimen failed to demonstrate a considerable response rate compared with monotherapy for relapsed or refractory SCLC. However, the combination of topotecan and etoposide could be further studied for sensitive relapsed patients pretreated with irinotecan and platinum No significant financial relationships to disclose.

4072 Background: S-1, a novel oral fluoropyrimidine, plus cisplatin (SP) regimen is one of the standard chemotherapy as first-line for advanced gastric cancer. ToGA study demonstrated that trastuzumab (T-mab) combination regimen improved the overall survival of patients with HER2-positive advanced gastric cancer. However, there was no study evaluating the efficacy and the safety of T-mab in combination with S-1 plus cisplatin (SP) regimen. Therefore, we planned this study to examine the efficacy and the safety of the SP plus T-mab. Methods: Patients confirmed to be HER2-positive by IHC and/or FISH (IHC 3+ or IHC 2+ and FISH positive) received S-1 at 80 mg/m2 po, day 1-14, and cisplatin 60 mg/m2 iv, day 1 plus trastuzumab 8 mg/kg iv, day 1 (6 mg/kg iv, d1 from 2nd course), repeated every 3 weeks until disease progression. Primary endpoint was response rate (RR). Secondary endpoints were progression-free survival, overall survival and safety. The threshold response rate was defined as 35%, and the expected rate was set at 50% with a 80% power and a 1-sided alpha value of 0.1 and the calculated sample size was 50 patients. Results: A total of 56 patients (median age 66) were enrolled in this study. The efficacy and the safety analyses were conducted in the full analysis set of 53 patients. (Two patients were excluded for ineligibility and one was for no treatment). The confirmed RR assessed by the independent review committee was 67.9% (95% CI: 53.7 – 80.1), and the disease control rate was 94.3%. The median PFS was 7.1 months (95% CI: 6.0 – 10.1). The median OS was not reached. (The median follow-up time: 9.2 months) The main grade 3/4 adverse events were as follows: neutropenia 34%, leucopenia 8%, anorexia 23%, diarrhea 8%, hypoalbuminemia 4%, vomiting 6%, and increased creatinine 6%. Conclusions: This tri-week regimen with SP plus T-mab showed promising results in patients with HER2-positive advanced gastric cancer. Clinical trial information: UMIN000005739.

291 Background: Trametinib, an oral MEK1/2 inhibitor, holds promise for tumors that frequently harbor RAS activating mutations, such as pancreatic cancer. Trametinib monotherapy or in combination with gemcitabine showed preliminary activity in patients (pts) with advanced pancreatic cancer. Methods: Eligible pts with untreated metastatic pancreatic cancer were randomized (double-blind, 1:1) to receive gemcitabine 1000 mg/m2 intravenously weekly x 7 for 8 weeks, then weekly x 3 every 4 weeks, plus either trametinib 2 mg or placebo daily. The primary endpoint was overall survival (OS); secondary endpoints included progression-free survival (PFS), overall response rate (ORR), and duration of response (DoR). OS and ORR were also analyzed based on baseline KRAS status as determined in plasma cell free DNA (cfDNA). Results: Baseline characteristics for the 160 randomized and treated pts were similar across arms. Skin related events (73% vs. 34%), diarrhea (54% vs. 28%), thrombocytopenia (40% vs. 28%), and stomatitis (36% vs. 8%) were more frequent with trametinib, as was grade 3/4 anemia (22% vs. 11%). However, rates of grade ≥ 3 thrombocytopenia, neutropenia and febrile neutropenia were similar between the arms. More pts on trametinib arm required dose reduction or interruption due to AEs (68% vs. 49% and 74% vs. 43%, respectively). Median OS was 8.4 months with trametinib compared to 6.7 months with placebo [HR 0.98 (95% CI: 0.67, 1.44, p=0.453)]. Median PFS was 16 weeks on trametinib and 15 weeks on placebo arm. ORRs and median DoRs were 22% and 23.9 weeks and 18% and 16.1 weeks on trametinib and placebo arm, respectively. The median OS and ORR in the subgroup of pts with KRAS mutations (n=143) was similar to OS and ORR for all randomized pts. Conclusions: This is first randomized, placebo-controlled trial evaluating the combination of gemcitabine with a MEK inhibitor. There was an increased incidence of skin, GI, and hematologic toxicities with trametinib compared to placebo. The addition of trametinib did not improve OS, PFS, or response rate. These outcomes remained independent of KRAS mutations based on cfDNA. Clinical trial information: NCT01231581.

Abstract Abstract 1856 Background: Lenalidomide has proven to be a highly effective treatment in relapsed multiple myeloma (MM), particularly when used in combination with dexamethasone. However, over 30% of patients with myeloma have renal insufficiency and as lenalidomide is renally excreted, little information is available about its use in myeloma patients with impaired kidney function. Defining a safe and effective dose of lenalidomide in this context is critical. Objective: We undertook this study to establish the maximum tolerated dose of lenalidomide in three cohorts of patients with different levels of impaired renal function: Group A - patients with creatinine clearance (CrCl) between 30 and 60 mL/min, Group B - patients with CrCl <30 mL/min not on dialysis, and Group C - patients with CrCl < 30mL/min who are on dialysis. Secondary endpoints included response rate, progression free survival and overall survival. Methods: Eligible patients had previously treated MM with renal impairment defined as creatinine clearance < 60 mL/min measured within 21 days prior to registration. Patients previously treated with lenalidomide were required to demonstrate clinical response (any duration) or stable disease with progression-free interval of > 6 months from start of that therapy. All patients received dexamethasone 40 mg orally on days 1, 8, 15 and 22 of a 28-day cycle. Prophylactic anticoagulation consisted of either 81 mg or 325 mg per day of aspirin. Patients also received lenalidomide orally every 1 or 2 days on days 1 through 21 of a 28-day cycle, as described below (Table 1). Starting doses were as in US Product Insert. Dose escalation follows a standard 3+3 design. Results: There have been 23 patients enrolled into groups and cohorts as shown in Table 1. Median age was 73 (range 49–89) and 13 (57%) were women. ISS stage was advanced in all patients, 0 in stage 1, 4 (18%) in stage 2 and 19 (82%) in stage 3. The regimen was well tolerated. Indeed, the MTD has not been reached in any of the groups, as no DLTs have occurred to date. The most commonly reported clinical adverse events (all grades, independent of attribution) across all patients included infections, hyperglycemia, constipation, dizziness, hyponatremia, hypocalcemia and tremor. Hematological toxicities (grade 3–4) occurred in 13 out of 21 pts (62%), mostly neutropenia and thrombocytopenia. Grade 3–4 events at least possibly related to the regimen occurred in 70% and included pneumonia (26%) and otitis media (9%). Response was seen in 14 patients, resulting in an overall response rate of 61%. CR was seen in 1 patient (4%), VGPR in 2 patients (9%), PR in 11 patients (43%), and SD for 9 patients. With median follow-up of 15.5 months, median progression-free survival is 9.8 months and median overall survival is 22 months. Conclusion: Lenalidomide and dexamethasone is a safe and effective regimen in patients with multiple myeloma and renal insufficiency. It is also very well tolerated, although cytopenias are common but manageable. MTD has yet to be reached in each group, allowing for higher doses to be given than previously thought, including 25mg daily (for 21/28 days) in patients with CrCl 30–60 mL/min, 25 mg every other day (for 21/28 days) in patients with CrCl < 30 mL/min not on dialysis, and 10mg daily (for 21/28 days) in patients with CrCl < 30 mL/min on dialysis. These results will provide needed, clinically relevant dosing for lenalidomide in MM patients with renal insufficiency.

We conducted a phase IIIb/IV study (CheckMate 511) to determine if nivolumab 3 mg/kg plus ipilimumab 1 mg/kg (NIVO3+IPI1) improves the safety profile of the combination. PATIENTS AND METHODS Patients (N = 360) age 18 years or older with previously untreated, unresectable stage III or IV melanoma were randomly assigned 1:1 to NIVO3+IPI1 or NIVO1+IPI3 once every 3 weeks for four doses. After 6 weeks, all patients received NIVO 480 mg once every 4 weeks until disease progression or unacceptable toxicity. The primary end point was a comparison of the incidence of treatment-related grade 3 to 5 adverse events (AEs) between groups. Secondary end points included descriptive analyses of objective response rate, progression-free survival, and overall survival. The study was not designed to formally demonstrate noninferiority of NIVO3+IPI1 to NIVO1+IPI3 for efficacy end points. RESULTS At a minimum follow-up of 12 months, incidence of treatment-related grade 3 to 5 AEs was 34% with NIVO3+IPI1 versus 48% with NIVO1+IPI3 ( P = .006). In descriptive analyses, objective response rate was 45.6% in the NIVO3+IPI1 group and 50.6% in the NIVO1+IPI3 group, with complete responses in 15.0% and 13.5% of patients, respectively. Median progression-free survival was 9.9 months in the NIVO3+IPI1 group and 8.9 months in the NIVO1+IPI3 group. Median overall survival was not reached in either group. CONCLUSION The CheckMate 511 study met its primary end point, demonstrating a significantly lower incidence of treatment-related grade 3-5 AEs with NIVO3+IPI1 versus NIVO1+IPI3. Descriptive analyses showed that there were no meaningful differences between the groups for any efficacy end point, although longer follow up may help to better characterize efficacy outcomes.
