Licofelone and naproxen were equally effective in reducing OA symptoms; however, licofelone significantly reduced cartilage volume loss over time, thus having a protective effect in patients with knee OA. This study proves the superiority of quantitative MRI over x-ray examinations in a multicentre clinical trial.

BackgroundLipegfilgrastim is a novel glyco-pegylated granulocyte-colony stimulating factor in development for neutropenia prophylaxis in cancer patients receiving chemotherapy. This phase III, double-blind, randomized, active-controlled, noninferiority trial compared the efficacy and safety of lipegfilgrastim versus pegfilgrastim in chemotherapy-naïve breast cancer patients receiving doxorubicin/docetaxel chemotherapy.MethodsPatients with high-risk stage II, III, or IV breast cancer and an absolute neutrophil count ≥1.5 × 109 cells/L were randomized to a single 6-mg subcutaneous injection of lipegfilgrastim (n = 101) or pegfilgrastim (n = 101) on day 2 of each 21-day chemotherapy cycle (4 cycles maximum). The primary efficacy endpoint was the duration of severe neutropenia during cycle 1.ResultsCycle 1: The mean duration of severe neutropenia for the lipegfilgrastim and pegfilgrastim groups was 0.7 and 0.8 days, respectively (λ = −0.218 [95% confidence interval: –0.498%, 0.062%], p = 0.126), and no severe neutropenia was observed in 56% and 49% of patients in the lipegfilgrastim and pegfilgrastim groups, respectively. All cycles: In the efficacy population, febrile neutropenia occurred in three pegfilgrastim-treated patients (all in cycle 1) and zero lipegfilgrastim-treated patients. Drug-related adverse events in the safety population were reported in 28% and 26% of patients i006E the lipegfilgrastim and pegfilgrastim groups, respectively.ConclusionThis study demonstrates that lipegfilgrastim 6 mg is as effective as pegfilgrastim in reducing neutropenia in patients with breast cancer receiving myelosuppressive chemotherapy.Trial RegistrationEudra EEACTA200901599910The study protocol, two global amendments (Nos. 1 and 2), informed consent documents, and other appropriate study-related documents were reviewed and approved by the Ministry of Health of Ukraine Central Ethics Committee and local independent ethics committees (IECs).

BackgroundPharmacokinetic studies with XM17 (Ovaleap®), a recombinant human follicle-stimulating hormone (r-hFSH, follitropin alfa), have demonstrated good safety and tolerability in healthy women whose endogenous FSH levels were down-regulated with a long agonist protocol. In these studies, Ovaleap® pharmacokinetics were dose-proportional and bioequivalent to the reference follitropin alfa product (Gonal-f®). The objective of the present study is to determine whether Ovaleap® is equivalent to Gonal-f® with respect to the number of oocytes retrieved in infertile but ovulatory women undergoing assisted reproductive technology (ART) therapy.MethodsThis multinational, multicenter, randomized (1:1), active-controlled, assessor-blind, comparative study included infertile normally gonadotrophic women 18 to 37 years old with a body mass index of 18 to 29 kg/m2 and regular menstrual cycles of 21 to 35 days undergoing ART therapy. During a 5-day fixed-dose phase, women received 150 IU/day of Ovaleap® (n = 153) or Gonal-f® (n = 146), followed by an up to 15-day dose-adaptation phase during which doses could be adjusted every 3 to 5 days, up to a maximum of 450 IU/day. Ovaleap® was to be deemed equivalent to Gonal-f® if the two-sided 0.95 confidence interval (CI) for the difference in the number of oocytes retrieved fell within the equivalence range of ±3 oocytes.ResultsSimilar numbers of oocytes were retrieved in the 2 treatment groups. The mean ± SD number of oocytes retrieved was 12.2 ± 6.7 in the Ovaleap® group and 12.1 ± 6.7 in the Gonal-f® group (intent-to-treat [ITT] population). Regression analysis estimated a mean difference of 0.03 oocytes between the treatment groups (95 % CI: −0.76-0.82), which was well within the prespecified equivalence range of ±3 oocytes. Ovaleap® and Gonal-f® showed favorable and comparable safety profiles, with no unexpected safety findings.ConclusionsOvaleap® has shown the same efficacy and safety as Gonal-f® for stimulation of follicular development in infertile women (up to 37 years of age) who are undergoing ART therapy.Trial RegistrationEudraCT: 2009-017674-20.

Background: A prospective randomized trial in patients with Crohn disease studied whether 6-thioguanine nucleotide (6-TGN) concentration-adapted azathioprine (AZA) therapy is clinically superior to a standard dose of 2.5 mg/kg/day AZA. Methods: After 2 weeks of standard therapy, patients (n ‫؍‬ 71) were randomized into standard (n ‫؍‬ 32) or adapted-dose (n ‫؍‬ 25) groups; 14 patients dropped out before randomization. In the adapted group, the AZA dose was adjusted to maintain 6-TGN concentrations between 250 and 400 pmol/8 ؋ 10 8 erythrocytes (Ery). Response criteria were the number of patients in remission after 16 weeks without steroids (primary) and remission after 24 weeks, frequency of side effects, and quality of life (secondary).Results: After 16 weeks, 14 of 32 (43.8%) patients in the standard group vs 11 of 25 (44%) in the adapted group were in remission without steroids (intent-to-treat analysis). After 24 weeks, 43.8% vs 40% were in remission. No significant differences were found concerning quality of life, disease activity, 6-TGN concentrations, AZA dose, or dropouts due to side effects. Sixty-six patients had a wild-type thiopurine S-methyltransferase (TPMT) genotype, with TPMT activities of 8 to 20 nmol/(mL Ery ؋ h). Five patients (dropouts after randomization) were heterozygous, with TPMT activities <8 nmol/(mL Ery ؋ h). 6-Methyl mercaptopurine (6-MMP) concentrations >5700 pmol/8 ؋ 10 8 Ery were not associated with hepatotoxicity. Conclusion: Standard and adapted dosing with the provided dosing scheme led to identical 6-TGN concentrations and remission rates. Adapted dosing had no apparent clinical benefit for patients with TPMT activity between 8 and 20 nmol/(mL Ery ؋ h). Additionally, 6-MMP monitoring had no predictive value for hepatotoxicity.

Background: Azathioprine (aza) therapy is beneficial in the treatment of inflammatory bowel disease, but 10%-30% of patients cannot tolerate aza therapy because of adverse drug reactions. Thiopurine S-methyltransferase (TPMT) deficiency predisposes to myelotoxicity, but its association with other side effects is less clear. Inosine triphosphatase (ITPA) mutations are other pharmacogenetic polymorphisms possibly involved in thiopurine metabolism and tolerance. Methods: We analyzed data from a 6-month prospective study including 71 patients with Crohn disease undergoing first-time aza treatment with respect to aza intolerance. Patients were genotyped for common TPMT and ITPA mutations and had pretherapy TPMT activity measured.
