BackgroundStandard care for treating anemia in patients with CKD includes use of erythropoiesis-stimulating agents, which sometimes involves increased risks of cardiovascular morbidity and mortality. Previous studies in patients with anemia and nondialysis-dependent CKD (NDD-CKD) found significantly elevated hemoglobin levels with use of vadadustat, an oral hypoxia-inducible factor prolyl hydroxylase inhibitor, compared with placebo.MethodsIn this phase 3, open-label, active-controlled noninferiority trial, we randomized 304 Japanese adults with anemia in NDD-CKD (including erythropoiesis-stimulating agent users and nonusers) to oral vadadustat or subcutaneous darbepoetin alfa for 52 weeks. The primary efficacy end point was average hemoglobin at weeks 20 and 24. Safety data included adverse events (AEs) and serious AEs.ResultsA total of 151 participants received vadadustat and 153 received darbepoetin alfa. Least squares mean of the average hemoglobin at weeks 20 and 24 was 11.66 (95% confidence interval [95% CI], 11.49 to 11.84) g/dl for vadadustat and 11.93 (95% CI, 11.76 to 12.10) g/dl for darbepoetin alfa. The 95% CIs for both treatments were within the target hemoglobin range (11.0–13.0 g/dl), and the lower 95% confidence limit for the difference between groups (−0.50 g/dl) was above the predefined noninferiority margin (−0.75 g/dl), demonstrating noninferiority of vadadustat to darbepoetin alfa. Similar proportions of patients in each group reported AEs and serious AEs. The most frequent AEs with vadadustat were nasopharyngitis, diarrhea, and constipation.ConclusionsIn Japanese patients with NDD-CKD, vadadustat was noninferior to darbepoetin alfa, was effective up to week 52 in terms of average hemoglobin, and was generally well tolerated. These results suggest that vadadustat may be a potential treatment for anemia in this patient population.

Abstract Background and Aims Vadadustat is a small-molecule inhibitor of hypoxia-inducible factor prolyl hydroxylase being developed for treatment of anemia associated with chronic kidney disease (CKD). The vadadustat phase 3 program includes four efficacy and cardiovascular safety outcome trials of vadadustat versus the erythropoiesis-stimulating agent (ESA) darbepoetin alfa. Here we describe detailed results on hematologic efficacy in two of the four phase 3, randomized, open-label, sponsor-blind trials (the INNO2VATE trials) in adult patients with dialysis-dependent (DD) CKD and anemia, where vadadustat met prespecified noninferiority criteria compared with darbepoetin alfa with respect to cardiovascular safety and correction/maintenance of hemoglobin (Hb) target concentrations. Method The mean screening Hb range for the incident DD-CKD trial (NCT02865850) was 8.0-11.0 g/dL; for the prevalent DD-CKD trial (NCT02892149), it was 8.0-11.0 g/dL in the United States (US) and 9.0-12.0 g/dL for non-US. Patients in the incident and prevalent DD-CKD trials had initiated dialysis within <16 weeks with limited or no prior ESA exposure and >12 weeks with established ESA treatment prior to screening, respectively. Vadadustat starting dose was 300 mg/day for all patients, whereas initial darbepoetin alfa dose depended on each patient’s prior dose or product label. Both vadadustat and darbepoetin alfa doses were titrated according to prespecified dosing algorithms to achieve target Hb concentrations (US: 10-11 g/dL; non-US: 10-12 g/dL) during the primary evaluation period (PEP; weeks 24-36) and the secondary evaluation period (SEP; weeks 40-52). Herein, we present topline results from PEP and SEP endpoints, as well as other, more detailed hematologic erythrocyte parameters. Results A total of 3923 patients (369 with incident DD-CKD and 3554 with prevalent DD-CKD) were randomized 1:1 to vadadustat or darbepoetin alfa. Vadadustat was noninferior to darbepoetin alfa in achieving target-range Hb concentrations (primary efficacy endpoint) among patients who were new to, or established on, dialysis. The respective proportions of patients (vadadustat vs. darbepoetin alfa) with an average Hb value within the geography-specific target range in the PEP and SEP were 43.6% versus 56.9% and 39.8% versus 41.0% in the incident trial and 49.2% versus 53.2% and 44.3% versus 50.9% in the prevalent dialysis trial. The proportion of patients who achieved an Hb increase >1.0 g/dL from baseline to week 52 was assessed only for the incident trial and was 84.0% (95% CI: 77.8%, 89.0%) for vadadustat versus 89.9% (95% CI: 84.7%, 93.8%) for darbepoetin alfa. Hematologic erythrocyte parameters at time points within the PEP and SEP are presented in Table 1. In the incident trial, reticulocyte count was slightly increased from baseline at 28 and 52 weeks for vadadustat, whereas for darbepoetin alfa, reticulocyte count was slightly decreased or unchanged in both trials. Erythrocyte mean corpuscular volume and erythrocyte mean corpuscular Hb showed increases by week 52 for both groups. Conclusion Vadadustat demonstrated similar profiles across erythrocyte parameters compared with darbepoetin alfa in the treatment of anemia associated with CKD in adults in both incident dialysis and prevalent dialysis settings.

The Difference

Patients with chronic myeloid leukemia in chronic phase (CML-CP) resistant or intolerant to ≥2 tyrosine kinase inhibitors (TKIs) are at high risk of experiencing poor outcomes due to disease biology and inadequate efficacy and/or safety of current therapies. Asciminib is a first-in-class STAMP (Specifically Targeting the ABL Myristoyl Pocket) inhibitor with the potential to overcome resistance or intolerance to approved TKIs. In this phase 3, open-label study, patients with CML-CP previously treated with ≥2 TKIs were randomized (2:1) to receive asciminib 40 mg twice daily vs bosutinib 500 mg once daily. Randomization was stratified by major cytogenetic response (MCyR) status at baseline. The primary objective was to compare the major molecular response (MMR) rate at week 24 for asciminib vs bosutinib. Two hundred and thirty-three patients were randomized to asciminib (n=157) or bosutinib (n=76). Median follow-up was 14.9 months. The MMR rate at week 24 was 25.5% with asciminib and 13.2% with bosutinib. The difference in MMR rate between treatment arms, after adjusting for MCyR at baseline, was 12.2% (95% CI, 2.19-22.30; 2-sided P=.029). Fewer grade ≥3 adverse events (50.6% vs 60.5%) and fewer adverse events leading to treatment discontinuation (5.8% vs 21.1%) occurred with asciminib than with bosutinib. The study showed a superior efficacy of asciminib compared with that of bosutinib, together with a favorable safety profile. These results support the use of asciminib as a new therapy in patients with CML-CP who are resistant or intolerant to ≥2 prior TKIs. The trial is registered at www.ClinicalTrials.gov as NCT03106779.

Abstract Background Tofacitinib is an oral, small-molecule JAK inhibitor for the treatment of ulcerative colitis (UC). Efficacy and safety were demonstrated in 3 Phase 3, randomised, placebo-controlled studies in patients with moderate to severe UC.1 An ongoing, Phase 3, open-label, long-term extension (OLE) study (OCTAVE Open, NCT01470612) included patients from OCTAVE Induction 1 and 2 and OCTAVE Sustain. Methods We present data (as of May 2019) from the ‘maintenance remission’ subpopulation in the OLE study who were in remission (total Mayo score ≤2, no individual subscore >1, rectal bleeding subscore of 0) at Week 52 of OCTAVE Sustain (having received tofacitinib 5 or 10 mg twice daily [BID]). These patients received tofacitinib 5 mg BID as per protocol in the OLE study. Efficacy data up to Month 36 of the OLE study (as observed and with non-responder and last observation carried forward imputation [NRI-LOCF]) are presented for this subpopulation. Safety data are reported for all patients who received tofacitinib 5 mg BID in the OLE study. Results Of 944 patients receiving ≥1 dose of tofacitinib in the OLE study, 163 were in remission at Week 52 of OCTAVE Sustain (mean age 45 years; 46.0% female). Of these, 66 (40.5%) and 76 (46.6%) received tofacitinib 5 and 10 mg BID, respectively, in OCTAVE Sustain, and 21 (12.9%) received a placebo. In total, 67/163 (41.1%) patients discontinued the OLE study, 16 (9.8%) due to adverse events (AEs) excl. worsening UC and 15 (9.2%) due to insufficient clinical response. Among patients that continued, efficacy (Table) was maintained over 36 months and was similar irrespective of the dose received in OCTAVE Sustain. Of 175 patients who received tofacitinib 5 mg BID (incl. 163 from the maintenance remission subpopulation), 152 (86.9%), 33 (18.9%) and 20 (11.4%) had AEs, serious AEs and severe AEs, respectively. The most frequent treatment-emergent AEs (TEAEs) were worsening UC (41 patients, 23.4%) and nasopharyngitis (38 patients, 21.7%). Six (3.4%) patients receiving tofacitinib 5 mg BID had serious infections, 11 (6.3%) had herpes zoster (non-serious and serious), 4 (2.3%) had opportunistic infections, 2 (1.1%) had major adverse cardiovascular events and 5 (2.9%) had malignancy (excl. non-melanoma skin cancer). No deep vein thrombosis, pulmonary embolism or deaths were reported in patients receiving tofacitinib 5 mg BID. Conclusion Most patients in remission at Week 52 of OCTAVE Sustain maintained efficacy with tofacitinib 5 mg BID over 36 months in the OLE study. Similar efficacy was observed for patients whose dose was reduced from tofacitinib 10 mg BID in OCTAVE Sustain to 5 mg BID in the OLE study, vs. those who received 5 mg BID throughout both OCTAVE Sustain and the OLE study. No new safety risks were identified. Reference

The Difference

11 Background: The use of trastuzumab has been established as the standard first-line treatment of HER2 positive (+) AGC. However, the role of anti-HER2 agents in the second-line treatment of HER2+ AGC has not been clearly established yet. TyTAN is the first randomized study to compare the efficacy and safety of adding lapatinib (L) to paclitaxel (P) vs P alone in the second-line treatment of HER2+ AGC. Methods: Eligibility required patients (pts) with AGC, amplification of HER2 by fluorescence in situ hybridization (FISH), and one prior regimen containing fluoropyrimidines and/or cisplatin. Pts were randomized 1:1 to L (1500mg QD) and P (80mg/m2, Day 1, 8, 15 q4w) or P alone. The treatments were given until disease progression or unacceptable toxicity. Stratification variables were prior trastuzumab treatment and gastrectomy status. Primary endpoint was overall survival (OS). Results: From March 2008 to June 2011, 1923 pts were screened and 430 pts were HER2+ AGC. 261 out of 430 pts were enrolled. All pts were from Asian countries: Japan (100), China (95), Korea (46), and Taiwan (20). Median OS was 11.0 months for L+P and 8.9 months for P alone in the intent-to-treat (ITT) population (HR 0.84; p=0.2088). In a pre-planned subgroup analysis, median OS in HER2 immunohistochemistry (IHC) 3+ subgroup was 14.0 months for L+P and 7.6 months for P alone (HR 0.59; p=0.0176). The endpoints in efficacy and AEs of special interest for L+P are summarized below (Table). Conclusions: Although OS was prolonged in L+P arm by 2 months, the difference was not statistically significant. HER2 IHC 3+ subgroup demonstrated statistically significant prolongation of OS by adding L. Clinical trial information: NCT00486954. [Table: see text]
