Baricitinib for relapsing giant cell arteritis: a prospective open-label 52-week pilot study.

ABSTRACT:

Background/purpose

Preclinical vascular inflammation models have demonstrated effective suppression of arterial wall lesional T cells through inhibition of Janus kinase 3 and JAK1. However, JAK inhibition in patients with giant cell arteritis (GCA) has not been prospectively investigated.

Methods

We performed a prospective, open-label, pilot study of baricitinib (4 mg/day) with a tiered glucocorticoid (GC) entry and accelerated taper in patients with relapsing GCA.

Results

15 patients were enrolled (11, 73% female) with a mean age at entry of 72.4 (SD 7.2) years, median duration of GCA of 9 (IQR 7-21) months and median of 1 (1-2) prior relapse. Four (27%) patients entered the study on prednisone 30 mg/day, 6 (40%) at 20 mg/day and 5 (33%) at 10 mg/day. Fourteen patients completed 52 weeks of baricitinib. At week 52, 14/15 (93%) patients had ≥1 adverse event (AE) with the most frequent events, including infection not requiring antibiotics (n=8), infection requiring antibiotics (n=5), nausea (n=6), leg swelling (n=2), fatigue (n=2) and diarrhoea (n=1). One subject required baricitinib discontinuation due to AE. One serious adverse event was recorded. Only 1 of 14 (7%) patients relapsed during the study. The remaining 13 patients achieved steroid discontinuation and remained in disease remission during the 52-week study duration.

Conclusion

In this proof-of-concept study, baricitinib at 4 mg/day was well tolerated and discontinuation of GC was allowed in most patients with relapsing GCA. Larger randomised clinical trials are needed to determine the utility of JAK inhibition in GCA.

Project description:BACKGROUND:The long-acting injectable antipsychotic aripiprazole once-monthly 400 mg (AOM 400) was recently approved for maintenance treatment of bipolar I disorder (BP-I). The purpose of this study was to evaluate the safety, tolerability, and efficacy of AOM 400 as long-term maintenance treatment for BP-I. METHODS:This open-label multicenter study evaluated the effectiveness of AOM 400 as maintenance treatment for BP-I by assessing safety and tolerability (primary objective) and efficacy (secondary objective). The study enrolled AOM 400-naive ("de novo") patients as well as AOM 400-experienced ("rollover") patients with BP-I from a lead-in randomized, placebo-controlled clinical trial that demonstrated the efficacy of AOM 400 in the maintenance treatment of BP-I (Calabrese et al. in J Clin Psychiatry 78:324-331, 2017). Safety variables included frequency and severity of treatment-emergent adverse events (TEAEs) and TEAEs resulting in study discontinuation. Efficacy was assessed by the proportion of patients maintaining stability throughout the maintenance phase, as well as mean changes from baseline in Young Mania Rating Scale (YMRS), Montgomery-Asberg Depression Rating Scale, and Clinical Global Impressions for Bipolar Disorder-Severity of Illness Scale (CGI-BP-S) total scores. Patient acceptability and tolerability of treatment was assessed using the Patient Satisfaction with Medication Questionnaire-Modified. RESULTS:Of 464 patients entering the maintenance phase, 379 (82%) were de novo and 85 (18%) were rollover. TEAEs were more common in de novo than rollover patients. The overall discontinuation rate due to TEAEs was 10.3% (48/464). Improvements in YMRS and CGI-BP-S total scores were maintained during the study, and the vast majority of both de novo (87.0%) and rollover (97.6%) patients maintained stability through their last visit. Overall, the need for rescue medication during the maintenance phase was minimal (<?10% of patients). Patient satisfaction levels were high, with both de novo and rollover patients rating the side effect burden of AOM 400 as greatly improved relative to previous medications. CONCLUSION:AOM 400 was safe, effective, and well tolerated by both de novo and AOM 400-experienced patients with BP-I for long-term maintenance treatment.

Project description:BackgroundThe current study evaluated the long-term (52 week) safety and impact on symptom measures of lurasidone (with or without lithium or valproate) for the treatment of bipolar I disorder in Japanese patients.MethodsBipolar patients for this open-label flexibly dosed lurasidone (20-120 mg/day) study were recruited from those with a recent/current depressive episode who completed an initial 6 week, double-blind, placebo-controlled, lurasidone study (depressed group), and those with a recent/current manic, hypomanic, or mixed episode (non-depressed group) who agreed to enroll directly into the long-term study. Measures of adverse events and safety included treatment-emergent adverse events, vital signs, body weight, ECG, laboratory tests, and measures of suicidality and extrapyramidal symptoms. Symptom measures included Montgomery Åsberg Depression Rating Scale (MADRS) and Young Mania Rating Scale (YMRS).ResultsThe most common adverse events associated with lurasidone were akathisia (30.7%), nasopharyngitis (26.6%), nausea (12.1%), and somnolence (12.1%). Minimal changes in lipids and measures of glycemic control occurred. Mean change in body weight was + 1.0 kg in the non-depressed group and - 0.8 kg in the depressed group. MADRS total scores declined by a mean (SD) of 2.0 (14.7) points from long-term baseline to endpoint in the depressed group who had received placebo in the prior 6 week trial. The depressed group that had received lurasidone during the prior 6 week study maintained their depressive symptom improvements. For the non-depressed group, YMRS total scores decreased over time.LimitationsNo control group was included, treatment was open-label, and 49.7% of patients completed the 52 week study.ConclusionsLong-term treatment with lurasidone 20-120 mg/day for Japanese patients with bipolar disorder maintained improvements in depressive symptoms for depressed patients who were treated in a prior 6 week trial and led to improvements in manic symptoms among a newly recruited subgroup of patients with a recent/current manic, hypomanic, or mixed episode. Few changes in weight or metabolic parameters were evident.Clinical trial registrationJapicCTI-132319, clinicaltrials.gov-NCT01986114.

Project description:IntroductionUpacicalcet is a novel injectable calcimimetic. This phase 3 multicenter open-label study aimed to assess the long-term efficacy and safety of upacicalcet in hemodialysis (HD) patients with secondary hyperparathyroidism (SHPT).MethodsJapanese HD patients with serum intact parathyroid hormone (iPTH) levels >240 pg/mL and corrected calcium (cCa) levels ≥8.4 mg/dL were enrolled. Upacicalcet with a dose range of 25-300 µg was administered after each dialysis for 52 weeks. The main efficacy endpoint was the percentage of patients achieving the target iPTH level (60-240 pg/mL).ResultsA total of 157 patients were enrolled, of whom 138 completed the study. Overall, 94.2% of patients achieved the target serum iPTH level at week 52. Neither symptomatic hypocalcemia nor cCa level <7.5 mg/dL occurred despite the negligible increase of concomitant vitamin D receptor activators and calcium carbonate. Upacicalcet improved the control of serum phosphate (P) and calcium levels regardless of baseline PTH levels and decreased intact fibroblast growth factor-23 levels. The largest parathyroid glands shrank, irrespective of their baseline volume or prior calcimimetic usage. Upacicalcet was well tolerated, with no adverse events requiring dose reduction.ConclusionThis is the first study to show that a calcimimetic improves serum P and cCa control without inducing severe hypocalcemia in patients with iPTH levels ≤300 pg/mL. Upacicalcet is efficacious in HD patients with mild-to-severe SHPT, with few safety concerns.IntroductionUpacicalcet is a novel injectable calcimimetic.

Project description:BackgroundTreatment goals for patients with systemic lupus erythematosus (SLE) include minimising disease activity and reducing the risk of flares. Although belimumab is effective at reducing disease activity and risk of severe flares, it was previously unknown what the clinical effects were upon treatment discontinuation. The objective of this study was to assess the impact of temporary withdrawal of intravenous (IV) belimumab in patients with SLE.MethodsThis multicentre, open-label, non-randomised, 52-week study (GSK Study BEL116027; NCT02119156) recruited patients with SLE and stable low disease activity, of whom those on belimumab 10 mg/kg IV plus standard therapy either discontinued belimumab for 24 weeks and then restarted belimumab 10 mg/kg IV every 4 weeks (q4w) for 28 weeks (treatment holiday [TH] group), or continued on belimumab 10 mg/kg IV plus standard therapy q4w for 52 weeks (treatment continuation [TC] group). The primary endpoint was median time to first Safety of Estrogens in Lupus Erythematosus National Assessment-SLE Disease Activity Index (SELENA-SLEDAI) Flare Index flare. Secondary and other endpoints included rate of any flare, time to severe flare, time to renal flare and rebound (SELENA-SLEDAI score exceeding parent study baseline). Data on rebound phenomenon in patients with any disease level of SLE who had permanently withdrawn from further belimumab treatment (long-term discontinuation group [LTD]) were also assessed. Safety was assessed.ResultsThe primary endpoint was not evaluable in the TH (n = 12) and TC (n = 29) groups as fewer than half of patients flared. Unadjusted flare rates per patient-year were 1.0 during treatment discontinuation and 0.3 during treatment restart (0.6 overall) in the TH group and 0.6 in the TC group; there were no severe or renal flares. No TH patients rebounded; 2 (6.9%) TC patients rebounded; 2 (5.1%) patients in the LTD group rebounded. There were no new safety signals.ConclusionsTwenty-four-week belimumab discontinuation did not appear to increase the risk of flares or rebound in patients with low SLE disease activity; flare rates were low in both groups. Further studies may help to fully determine the effect of belimumab discontinuation.Trial registrationClinicalTrials.gov, NCT02119156 . Registered on April 21, 2014.
