Objective An objective was to analyze the time course of efficacy of daily intravaginal administration of 0.5% (6.5 mg) DHEA (prasterone) for 52 weeks on the moderate to severe (MS) symptoms and signs of vulvovaginal atrophy (VVA). Method Five hundred twenty-one postmenopausal women were enrolled and received daily intravaginal administration of 0.5% DHEA in an open-label phase III study. The severity of the VVA symptoms examined in detail in the different groups. Results A parallel improvement of pain at sexual activity was observed in women who had moderate to severe (MS) dyspareunia as their most bothersome symptom (MBS) (n = 183) or not MBS (n = 240) and MS without being MBS (n = 57) with a 1.70 severity unit change in the MBS group for a decrease of 66.1% from baseline (p < 0.0001 versus baseline) over 52 weeks. A further improvement of dyspareunia, namely 0.33 severity unit (19.4%), was observed with continuing treatment from 12 weeks to 52 weeks. Similar results were observed on vaginal dryness and irritation/itching. Highly significant beneficial effects (p < 0.0001 versus baseline for all) were observed at gynecological examination on vaginal secretions, color, epithelial integrity and epithelial surface thickness. Conclusion The present study shows, in addition to the parallel benefits on the three symptoms of VVA, that the choice of any of the MS symptoms as being or not being MBS by women has no influence on the observed therapeutic effect (NCT01256671). © 2015 Elsevier Ireland Ltd.

Purpose: Romidepsin is a structurally unique, potent class 1 selective histone deacetylase inhibitor. The primary objective of this international, pivotal, single-arm, phase II trial was to confirm the efficacy of romidepsin in patients with relapsed or refractory peripheral T-cell lymphoma (PTCL). Patients and Methods: Patients who were refractory to at least one prior systemic therapy or for whom at least one prior systemic therapy failed received romidepsin at 14 mg/m 2 as a 4-hour intravenous infusion on days 1, 8, and 15 every 28 days. The primary end point was the rate of complete response/unconfirmed complete response (CR/CRu) as assessed by an independent review committee. Results: Of the 131 patients enrolled, 130 had histologically confirmed PTCL by central review. The median number of prior systemic therapies was two (range, one to eight). The objective response rate was 25% (33 of 130), including 15% (19 of 130) with CR/CRu. Patient characteristics, prior stem-cell transplantation, number or type of prior therapies, or response to last prior therapy did not have an impact on response rate. The median duration of response was 17 months, with the longest response ongoing at 34-months. Of the 19 patients who achieved CR/CRu, 17 (89%) had not experienced disease progression at a median follow-up of 13.4 months. The most common grade ≥ 3 adverse events were thrombocytopenia (24%), neutropenia (20%), and infections (all types, 19%). Conclusion: Single-agent romidepsin induced complete and durable responses with manageable toxicity in patients with relapsed or refractory PTCL across all major PTCL subtypes, regardless of the number or type of prior therapies. Results led to US Food and Drug Administration approval of romidepsin in this indication. © 2012 by American Society of Clinical Oncology.

Background: The Tufts Center for the Study of Drug Development (Tufts CSDD) collaborated with the Clinical Data Interchange Standards Consortium (CDISC) on a joint working group study with 10 participating companies including biopharmaceutical, CROs, and eClinical technology vendors. The objective of the study was to examine current and projected use of eClinical technology and standards across respondent organizations and in clinical studies and to gather perceptions and attitudes about technology and standards adoption. Methods: The Tufts CSDD study examined the use of eClinical technology and CDISC standards through a comprehensive survey combined with analyses of clinical study data among biopharmaceutical companies and contract research organizations. Results: The results suggest increasing use of specific eClinical technology solutions and standards. The barriers to adoption of eClinical trial tools are addressed as well as the benefits of standards adoption. Differences between respondent perceptions and actual study data are examined, and the survey results are compared with those from prior studies. Conclusions: The results of the study indicate that increasing use of standards could translate into improvements in time, costs, and overall approval rates. The study also observed an uptake in the use of eClinical technologies that could potentially create efficiencies and streamline operational processes. © 2015, © The Author(s) 2015.

The objective of the present phase III, placebo-controlled, double-blind, prospective and randomized study was to confirm the efficacy of daily intravaginal administration of 0.50% dehydroepiandrosterone (DHEA; prasterone) ovules for 12 weeks on moderate to severe dyspareunia (or pain at sexual activity) as most bothersome symptom of vulvovaginal atrophy (VVA) while having serum steroid concentrations within normal postmenopausal values. To this end, serum levels of DHEA, DHEA-sulfate (DHEA-S), Androst-5-ene-diol-3β, 17β-diol (5-diol), testosterone, dihydrotestosterone (DHT), androstenedione (4-dione), estrone (E1), estradiol (E2), estrone sulfate (E1-S), androsterone glucuronide (ADT-G), and androstane-3α, 17β-diol 17-glucuronide (3α-diol-17G) were measured by validated liquid chromatography-tandem mass spectrometry (LC-MS/MS). In agreement with the mechanisms of intracrinology, all serum sex steroids and metabolites concentrations after 12 weeks of daily intravaginal administration of 0.50% DHEA remain well within the limits of normal postmenopausal women. More specifically, the 12-week serum E2 concentration was measured at 22% below the average normal postmenopausal value (3.26 versus 4.17 pg/ml), thus eliminating any fear of E2 exposure outside the vagina. In addition, serum E1-S, a particularly reliable indicator of global estrogenic activity, shows serum levels practically superimposable to the value observed in normal postmenopausal women (219 versus 220 pg/ml). Similarly, serum ADT-G, the major metabolite of androgens, remains within normal postmenopausal values. The present data confirm the intracellular transformation of DHEA in the vagina resulting in local efficacy without any systemic exposure to sex steroids, observations which are in agreement with the physiological mechanisms of menopause. © 2015 Published by Elsevier Ltd.

Menopause | Year: 2016
Objective: The aim of this study is to confirm the local beneficial effects of intravaginal dehydroepiandrosterone (DHEA, Prasterone) on moderate to severe dyspareunia or pain at sexual activity, the most frequent symptom of vulvovaginal atrophy due to menopause or genitourinary syndrome of menopause (GSM). Methods: In a prospective, randomized, double-blind, and placebo-controlled phase III clinical trial, the effect of daily intravaginal 0.50% DHEA (6.5 mg) (Prasterone, EndoCeutics) was examined on four coprimary objectives, namely percentage of parabasal cells, percentage or superficial cells, vaginal pH, and moderate to severe pain at sexual activity (dyspareunia) identified by the women as their most bothersome vulvovaginal atrophy symptom. The intent-to-treat population included 157 and 325 women in the placebo and DHEA-treated groups, respectively. Results: After daily intravaginal administration of 0.50% DHEA for 12 weeks, when compared to baseline by the analysis of covariance test, the percentage of parabasal cells decreased by 27.7% over placebo (P<0.0001), whereas the percentage of superficial cells increased by 8.44% over placebo (P<0.0001), vaginal pH decreased by 0.66 pH unit over placebo (P<0.0001), and pain at sexual activity decreased by 1.42 severity score unit from baseline or 0.36 unit over placebo (P=0.0002). On the other hand, moderate to severe vaginal dryness present in 84.0% of women improved at 12 weeks by 1.44 severity score unit compared to baseline, or 0.27 unit over placebo (P=0.004). At gynecological evaluation, vaginal secretions, epithelial integrity, epithelial surface thickness, and color all improved by 86% to 121% over the placebo effect (P<0.0001 for all comparisons with placebo). Serum steroid levels remained well within the normal postmenopausal values according to the involved mechanisms of intracrinology. The only side effect reasonably related to treatment is vaginal discharge due to melting of the vehicle at body temperature and this was reported in about 6% of the participants. Conclusions: The daily intravaginal administration of 0.50% (6.5 mg) DHEA (Prasterone) has shown clinically and highly statistically significant effects on the four coprimary parameters suggested by the US Food and Drug Administration. The strictly local action of Prasterone is in line with the absence of significant drug-related adverse events, thus showing the high benefit-to-risk ratio of this treatment based upon the novel understanding of the physiology of sex steroids in women. © 2016 The North American Menopause Society.
