Objectives: This is the first of a pair of studies designed to assess efficacy, safety and tolerability of onabotulinumtoxinA (BOTOX®) as headache prophylaxis in adults with chronic migraine. Methods: The Phase III REsearch Evaluating Migraine Prophylaxis Therapy 1 (PREEMPT 1) is a phase 3 study, with a 24-week, double-blind, parallel-group, placebo-controlled phase followed by a 32-week, open-label phase. Subjects were randomized (1:1) to injections every 12 weeks of onabotulinumtoxinA (155 U–195 U; n = 341) or placebo ( n = 338) (two cycles). The primary endpoint was mean change from baseline in headache episode frequency at week 24. Results: No significant between-group difference for onabotulinumtoxinA versus placebo was observed for the primary endpoint, headache episodes (−5.2 vs. −5.3; p = 0.344). Large within-group decreases from baseline were observed for all efficacy variables. Significant between-group differences for onabotulinumtoxinA were observed for the secondary endpoints, headache days ( p = .006) and migraine days ( p = 0.002). OnabotulinumtoxinA was safe and well tolerated, with few treatment-related adverse events. Few subjects discontinued due to adverse events. Conclusions: There was no between-group difference for the primary endpoint, headache episodes. However, significant reductions from baseline were observed for onabotulinumtoxinA for headache and migraine days, cumulative hours of headache on headache days and frequency of moderate/severe headache days, which in turn reduced the burden of illness in adults with disabling chronic migraine.

Objectives: This is the second of a pair of studies designed to evaluate the efficacy and safety of onabotulinumtoxinA (BOTOX®) for prophylaxis of headaches in adults with chronic migraine. Methods: PREEMPT 2 was a phase 3 study, with a 24-week, double-blind, placebo-controlled phase, followed by a 32-week, open-label phase. Subjects were randomized (1:1) to injections of onabotulinumtoxinA (155U–195U; n = 347) or placebo ( n = 358) every 12 weeks for two cycles. The primary efficacy endpoint was mean change in headache days per 28 days from baseline to weeks 21–24 post-treatment. Results: OnabotulinumtoxinA was statistically significantly superior to placebo for the primary endpoint, frequency of headache days per 28 days relative to baseline (−9.0 onabotulinumtoxinA/−6.7 placebo, p < .001). OnabotulinumtoxinA was significantly favoured in all secondary endpoint comparisons. OnabotulinumtoxinA was safe and well tolerated, with few treatment-related adverse events. Few patients (3.5% onabotulinumtoxinA/1.4% placebo) discontinued due to adverse events. Conclusions: The results of PREEMPT 2 demonstrate that onabotulinumtoxinA is effective for prophylaxis of headache in adults with chronic migraine. Repeated onabotulinumtoxinA treatments were safe and well tolerated.

Background: The combination of carfilzomib with immunomodulatory drugs (IMiDs) and dexamethasone is active in multiple myeloma (MM). Carfilzomib, thalidomide, and dexamethasone (KTd) has been studied in upfront MM treatment but has not been studied in the setting of relapsed/refractory myeloma (RRMM). The ALLG MM018/ AMN002 is an open-label phase II study of KTd in patients with RRMM. This study was conducted across 16 sites across Australia, New-Zealand, Singapore, South Korea and Taiwan. Method: Patients with RRMM with 1-3 prior lines of treatment were given carfilzomib [K: 20mg/m2 IV cycle 1 days 1 and 2, 56mg/m2 (36mg/m2 for patients age ≥75 years) from cycle 1 day 8 onwards], thalidomide (T: 100mg po nocte) and dexamethasone [dex: 40mg (20mg for patients age ≥75 years) po weekly], in a 28-day cycle. After 12 cycles, T was omitted, and K was given on days 1,2,15,16 and dex days 1,15 every 28-day cycles for a further six cycles. The primary endpoint was PFS. Secondary endpoints were ORR, overall survival, adverse events, and quality of life (QoL). The study had an 80% power to detect a ≥70% PFS at 6.5 months compared to historical ≤50% PFS at 6.5 months expected with Td (Kropff, M. et al. Haematologica 2012), at a significance level of 0.05. Results: This study has completed accrual. Eighty-three patients [median age of 66 years (42-85)] were enrolled with a median follow up of 15.9 (0.9-26) months. ORR rates were 86.4% (≥VGPR 70.2%). Median PFS was 20m (95% CI 15.9-26m). PFS at 6.5 months was 76.2% (95% CI 73.6-84.9%). Median OS has not been reached, and was 75% at 20 months. The most common grade ≥3/4 AEs were peripheral neuropathy (16%), upper respiratory tract infections (12%), dyspnoea (14%), and hypertension (10%). Grade ≥3/4 cardiac AEs occurred in 6%. The median carfilzomib dose that was delivered was 70.7% (32.8-92.6%) of the target dose. Thus far, 41% of patients have completed the intended 18 cycles of treatment. 21% of patients ceased therapy early. The most common reason for early treatment cessation was disease progression (30%) and adverse events (15%). Fifteen patients (18%) have died, 11 were due to MM, two from infection, one from an ischaemic cardiac event, and one from a traffic accident. QoL, as measured by the EQ-5D-5L instrument, remained stable throughout treatment. Conclusion: The ALLG MM018/AMN 002 study has met its primary endpoint. The KTd schedule as outlined in this study is efficacious in patients with RRMM, resulting in a prolonged PFS and a safety profile in line with previous reports for each of carfilzomib and thalidomide. KTd is an active option in jurisdictions where the cost of other IMiDs prohibits regulatory funding. Comparisons of efficacy and adverse events between the Caucasian and Asian populations will be presented at the meeting.

ObjectiveTo evaluate the efficacy and safety of oral levosimendan in patients with amyotrophic lateral sclerosis (ALS). This phase II, randomised, double-blind, placebo-controlled, crossover, three-period study with 6 months open-label follow-up enrolled adults with ALS and sitting slow vital capacity (SVC) 60%–90 % of predicted from 11 sites in four countries.MethodsPatients received levosimendan 1 mg daily, 1 mg two times a day or placebo during three 14-day crossover periods and levosimendan 1–2 mg daily during open-label follow-up. Primary endpoint was sitting SVC; secondary endpoints included supine SVC, ALS Functional Rating Scale-Revised (ALSFRS-R), tolerability and safety.ResultsOf 66 patients randomised, 59 contributed to the double-blind results and 50 entered open-label follow-up. Sitting SVC was not significantly different between the treatments. In post hoc analysis using period-wise baselines, supine SVC favoured levosimendan over placebo, estimated mean differences from baseline being −3.62% on placebo, +0.77% on levosimendan 1 mg daily (p=0.018) and +2.38% on 1 mg two times a day (p=0.001). Headache occurred in 16.7% of patients during levosimendan 1 mg daily (p=0.030), 28.6% during 1 mg two times a day (p=0.002) and 3.3% during placebo. The respective frequencies for increased heart rate were 5.1% (p=0.337), 18.5% (p=0.018) and 1.7%. No significant differences between the treatments were seen for other adverse events.ConclusionsLevosimendan did not achieve the primary endpoint of improving sitting SVC in ALS. Headache and increased heart rate were increased on levosimendan, although it was otherwise well tolerated. A phase III study to evaluate the longer term effects of oral levosimendan in ALS is ongoing.

LBA10008 Background: Oral multikinase inhibitor regorafenib (REG) demonstrated substantial activity in a phase II trial in pts with GIST after failure of both IM and SU (J Clin Oncol. 2011; 29:606s; abstr 10007). This phase III, randomized, double-blind, placebo-controlled trial evaluated the efficacy and safety of REG for this unmet clinical need. Methods: Eligible pts had metastatic and/or unresectable GIST, objective failure of both prior IM and SU (progressive disease [PD] on, or intolerance to, IM and PD on SU), ≥1 measurable lesion, ECOG performance status 0 or 1. Pts were randomized 2:1 to receive best supportive care plus either REG 160 mg po once daily (3 wks on/1 wk off) or placebo (PL). The primary endpoint was progression-free survival (PFS) (modified RECIST 1.1, independent central review). Secondary endpoints included overall survival (OS), disease control rate (DCR, defined as rate of partial response [PR] plus stable disease [SD] lasting for ≥12 wks), response rate and duration, safety and correlative genotype analyses. At time of PD, pts were eligible for unblinding and crossover to open-label REG. Results: Between Jan and Aug of 2011, 234 pts were screened; 199 were randomized (REG: 133, PL: 66). Pts were stratified at randomization according to number of prior systemic therapies and geographical region. Baseline characteristics were balanced between the two arms. The primary endpoint was met: median PFS was 4.8 months for REG vs. 0.9 months for PL. Hazard ratio for PFS was 0.27 (95% CI, 0.18-0.39), p<0.0001. PFS rates at 3 and 6 months were 60% and 38% for REG vs. 11% and 0% for PL. DCR was 53% (REG) vs. 9% (PL).The HR for OS was 0.77 (p=0.20) with 85% PL pts having crossed over to REG. The most common > grade 3 treatment-emergent AEs in the REG arm during double-blind study were hypertension (28%), hand-foot skin reaction (21%), and diarrhea (8%). Conclusions: This randomized trial demonstrated that REG significantly improved PFS and DCR in pts with advanced GIST after failure of at least prior IM and SU. REG was well tolerated, with AEs as expected for this class and manageable with dose modifications.

TPS785 Background: The Toll-like receptor 9 agonist MGN1703 was compared to placebo in 59 metastatic CRC (mCRC) patients with disease control after standard induction chemotherapy in the double-blind randomized phase 2 IMPACT study. MGN1703 showed a superior effect over placebo, with a hazard ratio (HR) for the primary endpoint “PFS on maintenance” of 0.55 (p = 0.041) by local assessment and 0.56 (p = 0.070) by independent radiological review. Exploratory PFS analyses identified patients with objective RECIST response, normalized CEA and presence of activated NKT cells at the end of induction treatment to benefit the most from MGN1703. The OS evaluation showed a HR of 0.40 (median 24.5 vs. 15.1 months) for patients with RECIST response after induction therapy. Furthermore, at time of IMPACT study closure, 4 MGN1703 patients were still without progressive disease and continued treatment in compassionate use. As of August 2015, 3 patients were still receiving MGN1703 treatment in excess of three years (47-55 months), with 2 objective responses ongoing over 46 months. Methods: The international, multicenter, open-label phase 3 IMPALA study is conducted in collaboration with the AIO, TTD and GERCOR cooperative groups. In IMPALA, mCRC patients having achieved an objective tumor response following any type of first line induction therapy are randomized to receive MGN1703 switch maintenance monotherapy in the experimental arm or local standard of care in the control arm. In case of relapse, patients will reintroduce induction treatment whenever feasible, with those in the experimental arm continuing to receive MGN1703 therapy in the weeks without infusional chemotherapy. The primary endpoint of the study will be OS. Secondary endpoints include PFS, response rates, safety, and QoL in selected centers. Induction treatment, CEA and activated NKT at baseline are stratification factors and will be prospectively assessed. All randomized patients take part in a comprehensive immune monitoring plan evaluating cytokines and chemokines in serum and the activation status of immune cell populations. Recruitment started in September 2014 and the study is expected to recruit 540 patients within 24 months in 8 European countries. Clinical trial information: NCT02077868.

158 Background: There is an unmet medical need for effective treatments for patients with advanced pNET. Systemic therapies for advanced pNET are limited both by toxicity and efficacy. Everolimus, an oral mTOR inhibitor, has shown promising antitumor activity in 2 phase II studies, leading to further investigation in the largest phase III randomized controlled trial completed in pNET patients. Methods: Patients with advanced low- or intermediate-grade pNET were randomly assigned to everolimus 10 mg/d orally + best supportive care (BSC; n = 207) or placebo + BSC (n = 203). Long-acting somatostatin analogs (SSAs) were permitted as BSC during the study. The primary endpoint was progression free survival (PFS). At progression (RECIST), patients could be unblinded and those randomly assigned to placebo were offered open-label everolimus. Results: Compared with placebo, everolimus reduced the risk of progression by 65% and increased median PFS by more than 6 months, from 4.6 to 11.0 months (HR = 0.35; 95% CI: 0.27-0.45; p < 0.0001), by investigator review (primary endpoint). Median PFS by central review was consistent (HR = 0.34; 95% CI: 0.26 to 0.44; p < 0.001] in favor of everolimus. Eighteen-month PFS estimates were 34% for everolimus (95% CI: 26-43) vs 9% (95% CI: 4-16) for placebo. Everolimus demonstrated a significant PFS benefit across all patient subgroups according to baseline characteristics and prior SSA use. Prior SSA use was 49% in the everolimus arm and 50% in the placebo arm. Updated analyses of the impact of concomitant SSA will be reported. The most common drug-related adverse events were stomatitis, rash, diarrhea, fatigue, and infections (primarily upper respiratory); most were grade 1 or 2. Stomatitis (6.9% vs 0%), anemia (6% vs 0%), and hyperglycemia (5% vs 2%) were the most common grade 3-4 events. Conclusions: Everolimus significantly prolonged PFS compared with placebo in patients with advanced pNET in this large phase III clinical trial. This benefit was seen across all patient subgroups. Treatment resulted in a significant 6.4-month prolongation in median PFS. Everolimus had an acceptable and predictable safety profile. [Table: see text]

Jak2v617f Allele Burden

6514^ Background: Ruxolitinib is a potent and selective JAK1/2 inhibitor approved for the treatment of myelofibrosis (MF) based on results of the phase 3 COMFORT studies. Ruxolitinib demonstrated rapid and durable reductions in splenomegaly and improved MF-related symptoms and quality of life of patients (pts) with MF. Since one measure of efficacy is molecular response, this analysis correlates changes in mutant allele burden (%V617F) with spleen size reduction in COMFORT-II. Methods: COMFORT-II is a randomized, open-label, phase 3 study comparing ruxolitinib 15 or 20 mg twice daily (BID) with BAT. The primary endpoint was a ≥ 35% reduction in spleen volume from baseline (BL) at week 48. Change in %V617F was measured by allele specific qPCR. Pts were stratified by reduction in %V617F (< 10%, 10-20%, > 20%) and results were correlated with achievement of the primary endpoint. Results: More pts in the ruxolitinib arm had ≥ 10% V617F reductions compared with BAT (41% vs 5%; P = .01; Table). The majority of reductions > 20% were gradual and progressive over the course of the study; 2 pts had rapid reductions from 48% to 1% and 45% to 9% over 48 weeks. In the ruxolitinib arm, significantly more pts with a > 20% V617F reduction achieved the primary endpoint compared with pts with a < 10% reduction (79% vs 30%; P = .004); in each group, gender did not affect spleen response. For pts with < 10% reductions (15 mg BID, n = 16; 20 mg BID, n = 24), the average total daily dose (TDD) was ruxolitinib 29.6 mg; pts with > 20% reductions (15 mg BID, n = 3; 20 mg BID, n = 11) had a TDD of 35.3 mg. Conclusions: Pts who received ruxolitinib had larger reductions in JAK2V617F allele burden compared with BAT. %V617F reductions were gradual over the course of the 48-week study; longer follow-up is needed to determine the extent of allele burden reduction.

Background: Eptinezumab is approved in the US for the preventive treatment of migraine and was well tolerated in double-blind, placebo-controlled studies in patients with episodic and chronic migraine (CM). The PREVAIL study evaluated the long-term safety, immunogenicity, and impact on patient-reported outcomes of repeat doses of eptinezumab in patients with CM. Methods: PREVAIL was an open-label, phase 3 trial comprising two 48-week treatment phases. Adults with CM received eptinezumab 300 mg by 30-minute IV every 12 weeks for ≤8 doses, with patients followed up to week 104. Results: 128 adults (mean age, 41.5y) with CM were treated. Over 2 years, the most frequently reported treatment-emergent adverse events were nasopharyngitis (14.1%), upper respiratory tract infection (7.8%), sinusitis (7.8%), influenza (6.3%), bronchitis (5.5%), and migraine (5.5%). Study-drug discontinuation due to adverse events was 6.3%. Anti-eptinezumab antibody incidence peaked at week 24 and declined despite continued dosing, to nondetectable levels at week 104. Patient-reported outcomes were improved at first assessment (week 4) and generally sustained through week 104. Conclusions: In adults with CM, eptinezumab 300 mg demonstrated a favorable safety profile, limited long-term immunogenicity, early and sustained reductions in migraine-related burden, and improvements in health-related quality of life over 2 years.

Abstract Epoetin therapy for anemia in patients with chronic kidney disease (CKD) is widespread and effective. Currently available erythropoietins are produced in Chinese hamster ovary (CHO) cell lines. Epoetin delta (Dynepo®, Shire plc) is the only erythropoietin synthesized in a human cell line. We report data from a 24-week, double-blind, active-comparator study, followed by a 28 week open-label phase, designed to test whether epoetin delta was as effective as epoetin alfa in the treatment of anemia in patients receiving hemodialysis. Patients with hemoglobin levels of 9.6–12.4 g/dL who had been receiving epoetin therapy for at least 90 days were eligible for entry to the study. Patients were randomized to epoetin delta or epoetin alfa in a 3:1 ratio with the first dose of study medication identical to the last dose the patient received before entering the study. Subsequent dosing was adjusted according to a predefined algorithm to maintain hemoglobin within the target range of 10–12 g/dL. Efficacy was evaluated on the basis of weekly determinations of hematological parameters (hemoglobin, hematocrit, red blood cell [RBC] and reticulocyte count). The primary efficacy endpoint was average hemoglobin over Weeks 12, 16, 20 and 24 and to demonstrate that the difference in hemoglobin levels between the two groups was less than 1g/dL (90% CI contained within the range -1 to 1). Other key efficacy measures included the percentage of hemoglobin levels > 10g/dL and hematocrit levels > 30% and profiles of hematological parameters from baseline to Week 52. From the randomized population, 555 patients received epoetin delta and 191 received epoetin alfa. 583 finished the 24-week double-blind phase and all these patients passed into the open-label phase to be treated with epoetin delta. Adjusted average hemoglobin over Weeks 12–24 was 11.57 g/dL for the epoetin delta group and 11.56 g/dL for the epoetin alfa group. The difference between the groups was 0.01g/dL with both 90% CI (-0.13; 0.15) and 95% CI (-0.16; 0.17) within the predefined acceptable range of -1 to 1 g/dL demonstrating equivalence between the agents. 89.5 % of patients receiving epoetin delta had hemoglobin levels > 10 g/dL compared with 91.5% of patients receiving epoetin alfa. Average hemoglobin levels were maintained in the target range until the end of the study with no need to increase mean dose. Overall, treatment with epoetin delta at a mean dose of 63.7 IU/kg maintained hemoglobin levels at an average value of 11.31 g/dL over Weeks 12 through to the end of the study. In the double-blind phase the overall incidence of adverse events was similar between the study groups and at levels expected given the baseline characteristics of the study population. Hypotension, upper respiratory infection, muscle cramps and headache were the most commonly reported events overall and the levels were similar between the groups. Adverse events considered possibly related to treatment occurred in 11.6% of patients receiving epoetin delta compared with 8.4% of patients receiving epoetin alfa. No patient in this study developed neutralizing anti-erythropoietin antibodies to either epoetin alfa or epoetin delta. Epoetin delta was demonstrated to be as effective as epoetin alfa for maintenance of hemoglobin levels in CKD patients requiring hemodialysis. Control of hemoglobin level was maintained over 52 weeks without the need to increase average dose and epoetin delta was well tolerated for up to one year of exposure.

4138 Background: Everolimus (EVE) antitumor efficacy in patients (pts) with advanced NET was demonstrated in 2 double-blind, placebo (P)–controlled, phase III trials (RADIANT-2 and RADIANT-3). Median PFS in pancreatic (pNET) pts was 11.0 months (EVE) vs. 4.6 months (P) (HR 0.35, 95% CI 0.27-0.45, P <0.001) in RADIANT-3. Median EVE exposure in RADIANT-3 was 38 wks. EVE was approved for advanced pNET in the US and Europe in 2011. An expanded access protocol was launched to gather additional safety data and provide access to EVE for pts with advanced NET while awaiting regulatory approval. Methods: Pts aged ≥18 years with biopsy-proven NET; WHO performance status 0-2; and adequate bone, hepatic, and renal function were enrolled. Main exclusion criteria were poorly differentiated NET and cytotoxic therapy within 4 wks of enrollment. EVE (10 mg/d) was administered until disease progression, unacceptable toxicity, discontinuation, death, commercial availability of EVE, or until May 30, 2012. Pts were enrolled from April 21, 2011 to April 20, 2012. Primary objective was grade 3/4 and serious adverse events (AEs). Secondary objectives included investigator-assessed best overall response rate and PFS. Results: The full analysis set included 246 pts (pNET, n=126; non-pNET, n=120); the safety set included 240 pts (pNET, n=123; non-pNET, n=117). Median age was 61 and 66 years; 54% and 49% were male. Main primary tumor sites in non-pNET pts included small intestine (40%) and lung (22%). Median duration of EVE exposure was 12.1 wks and 24 wks in pNET and non-pNET. At data cutoff, there were 21 and 32 PFS events; 105 and 88 pts were censored. Grade 3/4 AEs were reported in 42.3% and 69.2% of pNET and non-pNET; those reported in ≥10% of pts in pNET and non-pNET included hyperglycemia (12.2% and 5.1%), diarrhea (10.6% and 31.6%), stomatitis (9.8% and 11.1%), nausea (8.1% and 10.3%), and anemia (5.7% and 11.1%). Median investigator-assessed PFS was 7.6 (95% CI 5.52-7.62) months and 10.8 (8.77-Not Estimable) months in pNET and non-pNET. Conclusions: EVE was well tolerated in pts with advanced NET. AEs were similar to those previously reported. Protocol-specified early termination of pts limits the interpretation of PFS medians. Clinical trial information: EudraCT Number: 2010-023032-17.
