Abstract Background and Aims C3 glomerulopathy (C3G) and immune complex membranoproliferative glomerulonephritis (IC-MPGN) are rare, progressive kidney diseases requiring a biopsy for definite diagnosis. Both C3G and IC-MPGN are attributed to complement dysregulation, with dysregulation of the alternative pathway established in C3G and implicated in IC-MPGN (alongside classical pathway activation by immune complexes). We describe the baseline biomarker and clinical characteristics of patients participating in two C3G/IC-MPGN phase II studies of the investigational, oral complement factor D (FD) inhibitor, danicopan (ALXN2040/ACH-4471). Method The first study (NCT03369236) was a double-blind, placebo-controlled, randomised, 6-month (+open label extension) trial of patients with biopsy-confirmed C3G of the native kidney treated with danicopan or placebo. The second study (NCT03459443) was a single-arm, open-label, 12-month (+extension) trial of patients with biopsy-confirmed C3G or IC-MPGN treated with danicopan. In both studies, all patients were to have proteinuria ≥500 mg/day and estimated glomerular filtration rate (eGFR) ≥30 mL/min/1.73 m2 (calculated by the Modification of Diet in Renal Disease equation for patients ≥18 years and the Schwartz equation for patients <18 years). Complement biomarkers including, but not limited to, C3, C4, AP activity, classical pathway activity, FD, Ba, Bb, sC5b-9, and C5 were measured in serum or plasma prior to dosing. Spearman correlation coefficients (rs) were determined between biomarkers of complement, eGFR, and/or proteinuria. Results A total of 35 patients were included in this analysis (13 from study 1 and 22 from study 2). The majority of patients were male (9 [69%] in study 1, 12 [55%] in study 2), with mean (SD) ages at baseline of 25.2 (7.63) years in study 1 and 24.3 (9.90) years in study 2. Most patients had received prior angiotensin converting enzyme inhibitors/receptor blockers (12 [92%] in study 1, 19 [86%] in study 2), and/or immunosuppressants (10 [77%] in study 1, 12 [55%] in study 2). Baseline clinical and biomarker data are shown in Table 1. Baseline eGFR was moderately correlated with proteinuria (uPCR24, rs=-0.40 [p=0.022]); baseline uPCR24 was also moderately correlated with Ba (rs=0.42 [p=0.016]) and FD (rs=0.53 [p=0.002]). Ba and FD elevations showed strong correlations with lower eGFR (rs=-0.79 and -0.88, respectively [p<0.0001]), as seen in Figure 1A and B. Reduced circulating C3 strongly correlated with increased sC5b-9 (rs=-0.70 [p<0.0001]) and reduced C5 level (rs=0.80 [p<0.0001]), as seen in Figure 1C and D. Conclusion Data from two danicopan clinical studies in C3G patients show correlations with renal impairment and proteinuria were observed for some, but not all, complement biomarkers. Factor Ba and FD are strongly associated with eGFR, suggesting that these biomarkers cannot easily be used as markers of complement dysregulation or activity. Interpretation of changes in these complement proteins needs to include not only the nature of the complement dysregulation and influence of the complement therapeutic being tested, but also eGFR. Additional urinary biomarkers, biopsy findings, autoantibodies, and genetic variants are currently being analysed and findings from this study will contribute to a better understanding of C3G and IC-MPGN.

ObjectivesAssess the efficacy and safety of tocilizumab in patients with systemic sclerosis (SSc) in a phase II study.MethodsPatients with SSc were treated for 48 weeks in an open-label extension phase of the faSScinate study with weekly 162 mg subcutaneous tocilizumab. Exploratory end points included modified Rodnan Skin Score (mRSS) and per cent predicted forced vital capacity (%pFVC) through week 96.ResultsOverall, 24/44 (55%) placebo-tocilizumab and 27/43 (63%) continuous-tocilizumab patients completed week 96. Observed mean (SD (95% CI)) change from baseline in mRSS was –3.1 (6.3 (–5.4 to –0.9)) for placebo and –5.6 (9.1 (–8.9 to–2.4)) for tocilizumab at week 48 and –9.4 (5.6 (–8.9 to –2.4)) for placebo-tocilizumab and –9.1 (8.7 (–12.5 to –5.6)) for continuous-tocilizumab at week 96. Of patients who completed week 96, any decline in %pFVC was observed for 10/24 (42% (95% CI 22% to 63%)) placebo-tocilizumab and 12/26 (46% (95% CI 27% to 67%)) continuous-tocilizumab patients in the open-label period; no patients had >10% absolute decline in %pFVC. Serious infection rates/100 patient-years (95% CI) were 10.9 (3.0 to 27.9) with placebo and 34.8 (18.0 to 60.8) with tocilizumab during the double-blind period by week 48 and 19.6 (7.2 to 42.7) with placebo-tocilizumab and 0.0 (0.0 to 12.2) with continuous-tocilizumab during the open-label period.ConclusionsSkin score improvement and FVC stabilisation in the double-blind period were observed in placebo-treated patients who transitioned to tocilizumab and were maintained in the open-label period. Safety data indicated increased serious infections in patients with SSc but no new safety signals with tocilizumab.Trial registration numberNCT01532869; Results.

Objective.To evaluate the efficacy/safety of belimumab in patients with rheumatoid arthritis (RA).Methods.Patients fulfilling American College of Rheumatology (ACR) criteria for RA for ≥ 1 year who had at least moderate disease activity while receiving stable disease-modifying antirheumatic drug (DMARD) therapy and failed ≥ 1 DMARD were randomly assigned to placebo or belimumab 1, 4, or 10 mg/kg, administered intravenously on Days 1, 14, and 28, and then every 4 weeks for 24 weeks (n = 283). This was followed by an optional 24-week extension (n = 237) in which all patients received belimumab. Primary efficacy endpoint was the Week 24 ACR20 response.Results.Week 24 ACR20 responses with placebo and belimumab 1, 4, and 10 mg/kg were 15.9%, 34.7% (p = 0.010), 25.4% (p = 0.168), and 28.2% (p = 0.080), respectively. Patients taking any belimumab dose who continued with belimumab in the open-label extension had an ACR20 response of 41% at 48 weeks. A similar ACR20 response (42%) at 48 weeks was seen in patients taking placebo who switched in the extension to belimumab 10 mg/kg. Greater response rates were observed in patients who at baseline were rheumatoid factor-positive, anticitrullinated protein antibody-positive, or tumor necrosis factor inhibitor-naive, or had elevated C-reactive protein levels, Disease Activity Score 28 > 5.1, or low B lymphocyte stimulator levels (< 0.858 ng/ml). Adverse event rates were similar across treatment groups.Conclusion.In this phase II trial, belimumab demonstrated efficacy and was generally well tolerated in patients with RA who had failed previous therapies.

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.

Abstract Abstract 2958 Background: Circularly permuted TRAIL (CPT) is a recombinant mutant of human Apo2L/TRAIL developed by Beijing Sunbio Biotech Co. Ltd. as a targeted therapy for multiple myeloma and other hematologic malignancies. CPT is a dual pro-apoptotic receptor agonist that directly activates both pro-apoptotic receptors TRAIL-R1 (DR4) and TRAIL-R2 (DR5). CPT selectively induces apoptosis in a variety of cancer cells, while sparing most normal cells in preclinical models. Objective: CPT as a mono-therapy has shown definitive activities for patients with relapsed or refractory multiple myeloma (Rel/Ref MM) in phase I and phase II studies. The aim of this study is to observe the effect and safety of CPT in combination with thalidomide for Rel/Ref MM patients. Methods: In this multiple-center, open-label, single arm phase II study, 43 Rel/Ref MM patients who had received prior therapies and were resistant to thalidomide were recruited. These patients were divided into three groups, and received CPT 5.0mg/kg, 8.0mg/kg, and 10.0mg/kg on days1–5 of each 21-day cycle, respectively, until having finished six cycle‘s treatment or progression disease or intolerant adverse events. All the patients received thalidomide 100mg daily until to the disease progression or intolerant adverse events. Clinical responses of CPT were assessed by an independent review committee according to the criteria of the European Group for Blood and Marrow Transplantation (EBMT). Results: Among the 43 patients, 41 patients can be evaluated. There were 11, 15 and 15 patients in the three groups respectively. Among the 41 patients, two patients achieved complete response (CR), three showed near complete responses (nCR), four exhibited partial responses (PR), and five obtained minor responses (MR). The total response rates were 34% (including MR or better than MR), or 22% (including PR or better than PR). Among the three groups, the dose of 10mg/kg seemed to be optimal with 26.7% response rate (including PR or better than PR), superior to the other two groups. Duration of response of CPT was not evaluated accurately, because most patients who achieved PR, nCR, or CR were progression free at the end of the trial. The common treatment related adverse events (≥10%) were neutropenia, leucopoenia, fever, AST/ALT/LDH elevation, and thrombocytopenia. The grade 3 non-haematological toxicities were AST elevation (4.65%) and LDH elevation (2.33%). The elevation of AST and LDH seems to be related to tumor lysis, but not to liver injury. The grade 4 haematological toxicities were neutropenia and thrombocytopenia (2.33%, respectively) which might be related to thalidomide. Conclusions: The CPT combined with thalidomide was well-tolerated and an effective regimen for the treatment of Rel/Ref MM. The combination of CPT and thalidomide seems to be superior to CPT alone in CR/nCR response rate. Disclosures: Zheng: Beijing Sunbio Biotech Co., Ltd.: Employment.

2527 Background: 5T4 is a tumour associated antigen that is widely expressed on the surface of most human adenocarcinomas, including colorectal, but rarely in normal cells. Modified Vaccinia Ankara (MVA) has been employed as a vaccine vector to deliver 5T4. Previously, MVA-5T4 has been evaluated in a phase I/II clinical trial in stage IV colorectal cancer patients. MVA-5T4 was shown to be safe and well tolerated and induced 5T4 specific immune responses in most patients. Furthermore, 5T4 specific antibody titres correlated with clinical benefit. Methods: Two open label phase II clinical trials were initiated in which patients with advanced colorectal cancer received MVA-5T4 in conjunction with either 5-FU/leukovorin and irinotecan (TV2-IFL; n=19 patients) or 5-FU/leukovorin and oxaliplatin (TV2-FOLFOX; n=17 patients). MVA-5T4 was administered up to 6 times, 2 prior to, 2 during and 2 post-chemotherapy. The primary objectives were to assess the safety and immunogenicity of MVA-5T4 given in combination with chemotherapy. Results: Recruitment to both trials is complete and MVA-5T4 was well tolerated in all ITT patients, with no serious adverse events being associated with MVA-5T4. 5T4-specific cellular and humoral immune responses were monitored before, during and after chemotherapy in all 23 per protocol patients (n=12 for TV2-IFL and n=11 for TV2-FOLFOX). Following vaccination, all 23 patients mounted 5T4 cellular and/or humoral responses. Immune responses were detectable during chemotherapy in the majority of patients. IFNγ ELISPOT responses to 5T4 peptides revealed precursor frequencies as high as 1 in 1000 PBMCs. Assessment of clinical responses in all PP patients demonstrated an overall response rate of 65% across both trials. Conclusions: MVA-5T4 is safe and well tolerated when administered in conjunction with IFL and FOLFOX chemotherapy regimens. Furthermore, 5T4 specific immune responses are induced in all per protocol patients and can be boosted or maintained during chemotherapy. Encouraging clinical responses have been observed and 5T4 immune responses shown to correlate with clinical benefit. [Table: see text]

TPS2103 Background: EGFRvIII is a constitutively active tumorigenic deletion mutation of EGFR. It is expressed in ~30% of primary GB where it is linked to poor long-term survival (Pelloski 2007). The investigational vaccine rindopepimut consists of the unique EGFRvIII peptide sequence conjugated to keyhole limpet hemocyanin (KLH), delivered intradermally (500ug with 150ug GM-CSF as an adjuvant). Remarkably consistent and promising results across 3 phase II studies in newly diagnosed, resected EGFRvIII+ GB (Lai 2011) represent a statistically significant improvement over a historical control cohort matched for major eligibility criteria (median overall survival [OS] = 24.4 - 24.6 vs. 15.2 months from diagnosis [m] and median progression-free survival [PFS] = 12.3 - 15.3 vs. 6.4 m). ACT IV, a phase III trial in this population, is ongoing. The immunosuppressive influence of residual/advanced GB presents a challenge to activation of efficacious antitumor immune responses. Anecdotal evidence (compassionate use cases, Sampson 2008) suggests that rindopepimut may induce specific immune responses and regression in multifocal and bulky residual tumors. Rindopepimut with BV, which inhibits VEGF and its immunosuppressive properties (including impaired maturation of dendritic cells and disruption of tumoral T cell infiltration [Johnson 2007, Shrimali 2010]) may further optimize EGFRvIII-specific immune response and antitumor activity. Methods: ReACT is a Phase II study of rindopepimut plus BV in patients (pts) with 1st or 2nd relapse of EGFRvIII+ GB. BV-naïve pts will be enrolled to Group 1 (n=70: randomized 1:1 to BV plus either rindopepimut/GM-CSF or control injection [low-dose KLH]) while BV-refractory patients will enter Group 2 (n=25: to receive BV plus open-label rindopepimut/GM-CSF). Concurrent with BV (10 mg/kg, q 2 wks), blinded treatment or open-label vaccine is given in priming phase (days 1, 15 and 29), then monthly until PD. Tumor response is assessed every 8 weeks, and patients are followed for survival after PD. Objectives are PFS at 6 months (primary), objective response rate, PFS, OS, safety, immunogenicity and elimination of EGFRvIII. ReACT opened to accrual in December 2011 (NCT01498328).

531 Background: Preclinical data suggest a key role for EGFR inhibition in delaying acquired resistance to ET in ER+ breast cancer (BC). Retrospective analyses of 2 Phase II studies suggested adding gefitinib to ET delayed PFS in ET naive (ETN) BC. This randomized, double-blind, placebo-controlled multi-center study (NCT01151215) was conducted to prospectively test the hypothesis that adding AZD8931, an inhibitor of EGFR, HER2 and HER3 signaling, to A would be beneficial in delaying endocrine resistance in an advanced ETN BC population. Methods: Post-menopausal women with ER+ and/or PR+, ETN, HER2-negative, advanced BC were randomized (1:1:1) to receive A (1 mg od) plus AZD8931 20 or 40 mg bd or placebo (P). The primary endpoint was PFS (ITT population). Data presented are from an interim analysis (data cutoff 31 Aug 2012; 39% pts had a progression event). Results: Between Jun 2010 and Jun 2012, 359 pts (median age 61 years) were randomized to A combined with AZD8931 20 mg (n=118), 40 mg (n=120) or P (n=121). At the interim analysis, median PFS in the AZD8931 20 mg, 40 mg and P arms was 10.9, 13.8 and 14.0 months, respectively; PFS HR (95% CI) for AZD8931 20 mg:P was 1.37 (0.91–2.06, P=0.135) and for AZD8931 40 mg:P was 1.16 (0.77–1.75, P=0.485). Deaths were reported for 20 (17%), 16 (13%) and 12 pts (10%) in the AZD8931 20 mg, 40 mg and P arms, respectively. Grade ≥3 AEs were reported for 22 (19%), 44 (37%) and 18 (15%) pts in the AZD8931 20 mg, 40 mg, and P arms, respectively, the most frequent being rash (0% vs 8% vs 2%), acneiform dermatitis (0% vs 7% vs 0%) and hypertension (3% vs 3% vs 2%). Serious AEs were reported for 12%, 14% and 9% pts in the AZD8931 20 mg, 40 mg and P arms, respectively, and discontinuation (of AZD8931 or P) due to an AE in 5%, 8% and 2% pts, respectively. Conclusions: Co-blockade of EGFR, HER2, HER3 in combination with aromatase inhibition does not appear to delay endocrine resistance to ETN BC. Based on the low probability of demonstrating superior efficacy with addition of AZD8931 to A and the overall risk/benefit, the study was closed at the recommendation of the IDMC and pts discontinued AZD8931. Clinical trial information: NCT01151215.

4109 Background: Retrospective data in some cancer types suggested a possible different toxicity profile with chemotherapy and targeted therapies according to gender. However, data from prospective studies are still very limited, especially in infrequent tumors such as NETs. Methods: Pts with advanced pancreatic and gastrointestinal NETs treated with pazopanib or lenvatinib in the multicenter open-label phase II studies PAZONET and TALENT respectively, were included in the analysis. Both studies were performed by Spanish Task Force Group for Neuroendocrine Tumors (GETNE). All toxicity grades with an incidence higher than 5% were considered for univariate review. Additionally, all grade 3-4 toxicities were analyzed separately. Results: 155 pts (47.7% female) with 1213 adverse events (AEs) (20% G3-4) divided in 121 categories were included. In female patients, liver toxicity, headache, pyrexia, nausea/vomiting, hair/skin disorders and dizziness were significantly more common (table). The only toxicity with higher incidence in men was dysphonia (OR 0.42, 95% CI 0.2-0.9, p 0.02). There were no gender differences in grade 3-4 toxicities. Conclusions: We observed significant differences in toxicity AEs by gender in two prospective phase II studies with MKIs in NETs patients. Potential different approach to manage toxicity may be adopted based on gender. [Table: see text]
