Abstract Ruxolitinib is a Janus kinase (JAK) (JAK1/JAK2) inhibitor that has demonstrated superiority over placebo and best available therapy (BAT) in the Controlled Myelofibrosis Study with Oral JAK Inhibitor Treatment (COMFORT) studies. COMFORT-II was a randomized (2:1), open-label phase 3 study in patients with myelofibrosis; patients randomized to BAT could crossover to ruxolitinib upon protocol-defined disease progression or after the primary end point, confounding long-term comparisons. At week 48, 28% (41/146) of patients randomized to ruxolitinib achieved ⩾35% decrease in spleen volume (primary end point) compared with no patients on BAT (P<0.001). Among the 78 patients (53.4%) in the ruxolitinib arm who achieved ⩾35% reductions in spleen volume at any time, the probability of maintaining response was 0.48 (95% confidence interval (CI), 0.35–0.60) at 5 years (median, 3.2 years). Median overall survival was not reached in the ruxolitinib arm and was 4.1 years in the BAT arm. There was a 33% reduction in risk of death with ruxolitinib compared with BAT by intent-to-treat analysis (hazard ratio (HR)=0.67; 95% CI, 0.44–1.02; P=0.06); the crossover-corrected HR was 0.44 (95% CI, 0.18–1.04; P=0.06). There was no unexpected increased incidence of adverse events with longer exposure. This final analysis showed that spleen volume reductions with ruxolitinib were maintained with continued therapy and may be associated with survival benefits.

Abstract Background Ruxolitinib is a potent JAK1/JAK2 inhibitor that has demonstrated rapid and durable reductions in splenomegaly, improved MF-related symptoms and quality of life (QoL), and prolonged survival in 2 phase 3 studies comparing ruxolitinib with placebo (COMFORT-I) and best available therapy (COMFORT-II). However, no clinical trial in pts with MF had been conducted in Asian countries, and only a limited number of Asian pts or healthy volunteers had been enrolled in any ruxolitinib study. Methods This study was an open-label phase 2 study evaluating ruxolitinib in Asian pts with PMF, PPV-MF, or PET-MF who had palpable splenomegaly ≥ 5 cm below the costal margin and intermediate-2– or high-risk MF by the International Working Group for Myelofibrosis Research and Treatment (IWG-MRT) criteria. Pts received starting doses of ruxolitinib 15 or 20 mg twice daily (bid) based on baseline platelet count (100-200 or > 200 × 109/L, respectively); dose adjustments balancing safety and efficacy were allowed to titrate each pt to their most appropriate dose. The primary endpoint was met if the proportion of pts achieving ≥ 35% reduction in spleen volume from baseline at week 24 was ≥ 27.5% as measured by MRI/CT. Symptomatic response was assessed as a secondary endpoint using the 7-day modified MF Symptom Assessment Form (MFSAF) v2.0 total symptom score (TSS) and European Organisation for Research and Treatment of Cancer QoL Questionnaire Core 30 (EORTC QLQ-C30). The study was conducted in China (n = 63), Japan (n = 30), Korea (n = 17), and Taiwan (n = 10). The data cutoff date for this analysis was 7 June 2013. Results Overall, 120 pts were enrolled (PMF, n = 80; PPV-MF, n = 21; PET-MF, n = 19), and their baseline characteristics were as follows: median age, 61 years (range, 25-80 years); 51.7% female; 69.2% intermediate-2 and 30.8% high risk by IWG-MRT criteria; median palpable spleen size, 15 cm (range, 5-45 cm); median spleen volume, 2159 cm3; 55.8% of pts had prior exposure to hydroxyurea. The median follow-up was 8.44 months; 22.5% of pts discontinued treatment, primarily for adverse events (AEs; 9.2%) and disease progression (7.5%). The median duration of treatment was 8.44 months (range, 0.5-21.7 months), and the median daily dose was 20.64 mg/day in the 15 mg bid group (n = 46) and 36.11 mg/day in the 20 mg bid group (n = 74). All pts were evaluable for achievement of the primary endpoint, 101 pts remained on study and were evaluable at week 24, and 96 pts had nonzero scores on the MFSAF-TSS and were evaluable for a reduction from baseline. Most pts who had assessments at week 24 (91% [92/101]) had a reduction from baseline in spleen volume (Figure). The study met the primary endpoint, with 31.7% (38/120) of all pts achieving ≥ 35% reduction from baseline at week 24. Overall, 38.3% (46/120) of pts achieved ≥ 35% reduction from baseline in spleen volume at any time on study. As measured by the 7-day MFSAF, 49% (47/96) of pts achieved ≥ 50% reduction from baseline in TSS (median reduction, 47.2%). Pts experienced an improvement from baseline at week 24 in EORTC global health status/QoL (mean change, 5.2). The most common nonhematologic AEs (≥ 10%) regardless of relationship to study medication included diarrhea (25.8%), upper respiratory tract infection (17.5%), ALT level increased (15.0%), pyrexia (15.0%), AST level increased (13.3%), cough (11.7%), herpes zoster infection (11.7%), nasopharyngitis (10.8%), constipation (10.0%), gamma-glutamyl transferase level increased (10.0%), and headache (10.0%), and most were grade 1/2. Serious AEs were reported for 24.2% of pts, and 65.8% of all pts had grade 3/4 AEs. The most common new or worsening laboratory abnormalities were low hemoglobin (all grade 3, 55.7%), low lymphocyte (grade 3/4, 19.5%), low platelet (grade 3/4, 15.3%), and low ANC (grade 3/4, 7.6%) levels. AEs observed in this study were consistent with those observed in the 2 large phase 3 COMFORT studies. Six pts (5%) died on treatment or within 30 days of discontinuation. Summary/conclusions Findings from this study demonstrated that ruxolitinib was relatively well tolerated in Asian pts with MF and provided substantial reductions in splenomegaly and modest improvements in MF-associated symptoms. The AEs observed with ruxolitinib treatment in this study are consistent with those observed in the large phase 3 COMFORT studies, and there were no new AEs associated with ruxolitinib in Asian pts with MF.

Abstract Background Polycythemia vera (PV) is the most common of the myeloproliferative neoplasms and is characterized by elevated hematocrit requiring phlebotomy, splenomegaly, a variety of symptoms and increased thrombotic risk. Ruxolitinib, a JAK1/JAK2 inhibitor, was well tolerated and achieved rapid and durable clinical responses in a phase 2 study of patients (pts) with PV who were resistant to or intolerant of hydroxyurea (HU). Pts experienced phlebotomy independence, resolution of splenomegaly, and improvements in white blood cell (WBC) counts, platelet (PLT) counts, and disease-related symptoms. Here, we describe the baseline (BL) characteristics and symptom burden of pts in a phase 3 study of ruxolitinib in pts with PV who are resistant to or intolerant of HU. Methods RESPONSE is a randomized (1:1), open-label, phase 3 study (NCT01243944) comparing the efficacy and safety of ruxolitinib with best available therapy (BAT) in pts with PV who are resistant to or intolerant of HU (modified European LeukemiaNet criteria), have splenomegaly, and require phlebotomy for inadequate hematocrit (Hct) control. Fourteen disease-related symptoms were assessed on a scale of 0 (absent) to 10 (worst imaginable) using the modified Myeloproliferative Neoplasm Symptom Assessment Form (MPN-SAF). Blinded data are presented here. Results BL demographic data are available for the 222 enrolled pts (Table). Apart from HU, other common prior medications for PV included interferons (15%), PLT aggregation inhibitors (10%), alkylating agents (3.6%), alkyl sulfonates (3.2%), pyrimidine analogues (1.8%), and nitrosoureas (1.4%). The majority of pts (54.5%) had 1 phlebotomy within 12 weeks prior to screening; 23.9% had 2 and 17.1% had 3 or more phlebotomies. RESPONSE BL demographics are generally similar in terms of age (60 years vs 57-67); sex (66% male vs 58%-68%); Hct (44% vs 45%-48%); and platelets (419 x 109/L vs 320-429 x 109/L) to other PV studies including trials of givinostat (Finazzi BJH 2013) and AOP2014 (Gisslinger ASH 2012) and the ECLAP-PV (Marchioli JCO 2005) and CYTO-PV studies (Marchioli NEJM 2012). At the time of writing, BL symptom data from the MPN-SAF were available for 164 pts (Table). Pts in this study reported a similar symptom burden as PV pts from a large study of pts with MPNs (Emanuel JCO 2012; N = 1425; PV, n = 538), including similar mean scores for early satiety, abdominal discomfort, concentration problems, night sweats, itching, and tiredness/fatigue. In addition, prior therapy may have adversely affected BL symptom burden, as many of these symptoms (concentration problems, night sweats, fatigue) have been shown to be worsened by the use of conventional therapy to strictly control Hct (< 45%) and cardiovascular risk (Emanuel EHA 2013). BL MPN-SAF symptom data for all 222 pts will be presented. In addition, correlations between BL EORTC QLQ-C30 and MPN-SAF scores will be presented. Summary/Conclusions Demographic and BL symptom data from the RESPONSE study demonstrated that pts with HU refractory or intolerant PV have a significant disease burden that includes a variety of symptoms. These findings are consistent with those of Emanuel (JCO 2012), which showed that pts with PV have a significant symptom burden and a reduced quality of life. Pts with PV in the RESPONSE study are representative of those who have been studied in other clinical trials for the treatment of PV.

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 BACKGROUND Ruxolitinib is a potent JAK1/JAK2 inhibitor that has demonstrated reductions in splenomegaly and disease-related symptoms, as well as improved survival, in patients with MF and has proved superior to placebo and best available therapy in the 2 phase 3 COMFORT studies. JUMP (JAK Inhibitor Ruxolitinib in Myelofibrosis Patients) is a phase 3b, expanded-access trial for countries with no access to ruxolitinib outside a clinical trial and was designed to assess the safety and efficacy of ruxolitinib in patients with MF. As of 03 June 2014, 2027 patients have been enrolled in 25 countries, with a planned enrollment of 2500 patients. METHODS Eligible patients had MF classified as high risk, intermediate (Int)-2 risk, or Int-1 risk, with a palpable spleen (≥ 5 cm from the costal margin). Patients received starting doses of ruxolitinib based on platelet counts at baseline (5 mg twice daily [bid; ≥ 50 to < 100 × 109/L], 15 mg bid [100 to 200 × 109/L], or 20 mg bid [> 200 × 109/L]). The primary endpoint was assessment of safety and tolerability of ruxolitinib. Additional analyses included changes in palpable spleen length and symptom scores as measured by the FACT-Lymphoma Total Score (FACT-Lym TS). The final analysis will be performed after all patients have completed 24 months of treatment or ended treatment due to commercial availability. RESULTS This analysis includes results for 1144 enrolled patients (primary MF, 58.8%; n = 673) who started treatment ≥ 1 year before the data cutoff date (01 Jan 2014). At baseline, median age was 68 y (range, 18-89 y); 46.7% were female; median palpable spleen length was 13 cm below the costal margin; median hemoglobin was 105 g/L (range, 44-200 g/L) and 40.3% of patients had hemoglobin levels ˂ 100 g/L; median platelet level was 256 × 109/L (75-1910 × 109/L); mean FACT-Lym TS was 41.9. Most patients (69%) remained on treatment (35.5%) or completed treatment per protocol (33.5%; transition to commercial drug). Primary reasons for discontinuation included adverse events (AEs; 13.8%), disease progression (7.1%), and death (3.8%). Median exposure was 11.1 months; the median average daily dose was 37.2 mg for patients starting at 20 mg bid (64%; n = 728) and 23.4 mg for patients starting at 15 mg bid (33%; n = 374). The majority of patients (75.7%) had dose increases/decreases and 23.9% had a dose interruption. The most common hematologic grade ≥ 3 AEs were anemia (33.0%), thrombocytopenia (12.5%), and neutropenia (3.9%), which led to discontinuation in 2.6%, 3.2%, and 0.3% of patients, respectively. Mean hemoglobin levels declined from baseline (108 g/L) to a nadir of 85 g/L at 8 to 12 weeks and increased to near-baseline levels after week 12; mean platelet levels decreased from baseline (318 × 109/L) to a nadir of 139 × 109/L and remained stable over time. The most common nonhematologic AEs (≥ 10%) were diarrhea (14.5%), pyrexia (13.3%), fatigue (12.9%), and asthenia (12.5%) and were primarily grade 1/2; grade ≥ 3 AEs were low overall (< 2%), except pneumonia (3.6%), which led to discontinuation in 6 patients (0.5%). Serious AEs were reported for 32.3% of patients. Rates of infections were low; all-grade infections ≥ 5% included nasopharyngitis (6.3%), urinary tract infection (6.0%), and pneumonia (5.3%). Tuberculosis was reported for 3 patients (0.3%; no grade 3/4); no hepatitis B was reported. At weeks 24 and 48, 55% (431/782) and 61% (301/497) of patients achieved a ≥ 50% reduction from baseline in palpable spleen length, respectively; 23% (181/782) and 18% (88/497) had 25% to 50% reductions. Most patients (69%; 733/1062) experienced a ≥ 50% reduction in spleen length from baseline at any time (Figure). Clinically significant improvements on the FACT-Lym TS were seen as early as week 4 and were maintained at week 48 (mean change from baseline: week 4, 11.0; week 48, 9.4; the range for the minimally important difference is 6.5 to 11.2 points). CONCLUSIONS The JUMP study includes the largest cohort of MF patients treated with ruxolitinib reported to date. Consistent with previous reports, the most common AEs were anemia and thrombocytopenia; however, they rarely led to discontinuation. As observed previously, the majority of patients experienced reductions in spleen length and clinically meaningful improvements in symptoms were observed with ruxolitinib treatment. Overall, the safety and efficacy profile of ruxolitinib in JUMP is consistent with that in the phase 3 COMFORT studies. Figure 1 Figure 1.

TPS4132 Background: Pts with adv G/GEJ cancer have an OS of ≈ 1 y, indicating an unmet medical need for new first-line treatments (Tx). Expression of the PD-1 ligands PD-L1/PD-L2 is observed in up to 40% of pts with G/GEJ cancer and is associated with poor prognosis. In a phase 3 study of the PD-1 inhibitor nivo vs placebo in pts with adv CTX-refractory (CTX-R; ≥ 2 lines) G/GEJ cancer, nivo reduced the risk of death by 37% (HR, 0.63; P < 0.0001) and increased the OS rate at 12 mo (27% vs 11%; Kang YK, et al. J Clin Oncol. 2017;35 (suppl 4S) [abstract 2]). In a phase 1/2 study in pts with CTX-R G/GEJ/esophageal cancer (79% ≥ 2 prior Tx lines), nivo 1 mg/kg + ipi 3 mg/kg had a manageable safety profile and resulted in 26% ORR (44% ORR in pts with PD-L1+ tumors), a median OS of 6.9 mo, and a 34% OS rate at 12 mo (Janjigian Y, et al. ASCO, 2016 [abstract 4010]). In the phase 1 CheckMate 012 trial, nivo + CTX had clinical activity and manageable safety in pts with NSCLC (Rizvi NA, et al. J Clin Oncol. 2016;34:2969-2979). These positive results support investigation of nivo, nivo + ipi, and nivo + CTX in earlier lines of Tx for G/GEJ cancer. The open-label, phase 3 CheckMate 649 trial will evaluate nivo + ipi and nivo + CTX vs CTX alone as first-line Tx for pts with adv G/GEJ cancer (NCT02872116). Methods: 1266 pts aged ≥ 18 y with untreated, inoperable adv/metastatic G/GEJ cancer (histologically confirmed adenocarcinoma) regardless of PD-L1 status will be randomized to receive either nivo + ipi, nivo + CTX (capecitabine/oxaliplatin [XELOX] or fluorouracil/leucovorin/oxaliplatin [FOLFOX]), or investigator choice of XELOX or FOLFOX. Tumor tissue for determination of PD-L1 status (Dako assay) must be provided from ≤ 6 mo before study Tx. No prior systemic Tx, including HER2 inhibitors, are allowed. Pts with known HER2+ status, suspected autoimmune disease, grade > 1 peripheral neuropathy, or active infection are excluded. Primary endpoint is OS in pts with PD-L1+ (≥ 1%) tumors. Other endpoints include OS in all pts; PFS and time to symptom deterioration in all pts and in pts with PD-L1+ tumors; and safety. Clinical trial information: NCT02872116.
