Background Oral finasteride is a well-established treatment for men with androgenetic alopecia (AGA), but long-term therapy is not always acceptable to patients. A topical finasteride formulation has been developed to minimize systemic exposure by acting specifically on hair follicles.Objectives To evaluate the efficacy and safety of topical finasteride compared with placebo, and to analyse systemic exposure and overall benefit compared with oral finasteride.Methods This randomized, double-blind, double dummy, parallel-group, 24-week study was conducted in adult male outpatients with AGA at 45 sites in Europe. Efficacy and safety were evaluated. Finasteride, testosterone and dihydrotestosterone (DHT) concentrations were measured. ResultsOf 458 randomized patients, 323 completed the study and 446 were evaluated for safety. Change from baseline in target area hair count (TAHC) at week 24 (primary efficacy endpoint) was significantly greater with topical finasteride than placebo (adjusted mean change 20.2 vs. 6.7 hairs; P < 0.001), and numerically similar between topical and oral finasteride.Statistically significant differences favouring topical finasteride over placebo were observed for change from baseline in TAHC at week 12 and investigator-assessed change from baseline in patient hair growth/loss at week 24. Incidence and type of adverse events, and cause of discontinuation, did not differ meaningfully between topical finasteride and placebo.No serious adverse events were treatment related. As maximum plasma finasteride concentrations were >100 times lower, and reduction from baseline in mean serum DHT concentration was lower (34.5 vs. 55.6%), with topical vs. oral finasteride, there is less likelihood of systemic adverse reactions of a sexual nature related to a decrease in DHT with topical finasteride.Conclusion Topical finasteride significantly improves hair count compared to placebo and is well tolerated. Its effect is similar to that of oral finasteride, but with markedly lower systemic exposure and less impact on serum DHT concentrations.
Acute respiratory infections (ARI) still represent a big challenge for paediatricians, especially in those children defined as "ailed" as they are more susceptible to such kinds of disease. In this paediatric population, the immune system is still under-developed with an evident alteration in cytokine levels. A clinical study was carried out in 5 sites in Russia with the intention to enroll children particularly susceptible to contract respiratory infections (defined as "ailing"), assigning them to a treatment group with pidotimod in comparison with a control group, treating them for 30 days and observing the reduction in the number of ARI episodes throughout the follow-up period (6 months). Moreover, changes in serum immunological markers were evaluated at baseline and 30 days after treatment discontinuation. One hundred and fifty-seven ailing children were enrolled and assigned to two arms: a main pidotimod treatment group or a control group. The percentage of incidence of ARIs in the observation period at three different time points was statistically significant (p < 0.05). At the end of the follow-up period (after 6 months), ARIs had developed in 72 children (92.3%) in the main group and in 79 patients (100%) in the control group. Concerning changes of the immunological markers, the treatment group showed a better profile of normalization compared to the control group. The 30-day pidotimod therapy course led to improvement/reduction in the rate of acute respiratory infection recurrence in ailing children within a 3-month period, with a quick elimination of symptoms and signs of infection and, as a result, a faster recovery. The normalisation of the content of the pro-inflammatory cytokine interleukin-8 confirmed the immune-modulatory effect of the investigational drug, underlying its prophylactic effect.
Background: Vulvovaginal atrophy is an inflammatory condition linked with estrogenic deficiency, as well as decreased lubrication. The study aimed at the objective measurements of vaginal moisture (RH%), in fertile women and in postmenopausal women before and during treatment with a non-estrogenic moisturizing gel. Methods: The study followed a stepwise design. Acute: 5 women with postmenopausal vaginal dryness were measured their RH% at baseline and 30 minutes after the application of a moisturizer. Fertile Controls: 20 women were measured in the follicular phase and 20 in the luteal phase. Chronic: Forty postmenopausal women with mild/moderate vaginal dryness were randomly assigned to treatment (once/day for the first week and twice/week for the following 11 weeks) or untreated control group. Primary parameter was RH%, done by means of a vaginal hygrometer manufactured and validated for the specific purpose. Secondary parameters were the evaluation of erythema and oedema, scored for severity. Results: Fertile women showed an average 93/95 RH%, independently on the cycle phase. Postmenopausal women had 49/69 RH% in absence of any treatment. A 37% increased RH% was observed 30 min after a single application. During chronic treatment, RH% measured not earlier than 2 hours after the application of the product, resulted 7.8% to 10.4% higher than baseline (p < 0.05). Erythema improved accordingly. Conclusions: The vaginal moisturizer proved to be safe and to increase vaginal moisture short after treatment initiation; moreover, its effect proved to be long lasting.
A randomized, double blind, and active reference-controlled study was carried out among 116 patients suffering from idiopathic Parkinson's disease (PD). The aim of the study was to compare the safety and efficacy of alpha-dihydroergocryptine (DHEC) vs. pramipexole (PRAM) as an adjunct symptomatic therapy to levodopa in PD patients. The motor symptoms, assessed by the Unified Parkinson's Disease Rating Scale (UPDRS) III subscale, was identified as efficacy target. Fifty-six patients were randomized to DHEC and 60 to PRAM. Patients included were under constant levodopa dose for at least 3 months before entering the study, with baseline UPDRS III ≥14. They underwent a 16-week treatment. Out of the 116 included patients, 85 (39 in DHEC group and 46 in PRAM group, respectively) completed the study protocol. In DHEC group, UPDRS III decreased by 24.2% from baseline at week 10 and by 28.1% at week 16. In PRAM group, UPDRS III decreased by 27.1% from baseline at week 10 and by 29.2% at week 16. The data were highly significant (p < 0.01) at each time point versus baseline, while no significant difference was noticed between treatments. Overall, the patient population did not show any clinically meaningful mood disturbances at baseline and the fluctuations of UPDRS I during treatment were devoid of clinical significance. Safety was fairly good in both groups. In conclusion, DHEC and PRAM proved to be effective and safe as adjunct therapy to levodopa in idiopathic PD. According to the research result, they have significantly improved the motor function of our patients.
