Efficacy, Safety and Immunogenicity of Sun's Ranibizumab Biosimilar in Neovascular Age-Related Macular Degeneration: A Phase 3, Double-Blind Comparative Study.

INTRODUCTION: The study aimed to evaluate comparability in terms of efficacy, safety and immunogenicity of Sun's ranibizumab biosimilar with reference ranibizumab in patients with neovascular age-related macular degeneration (nAMD). METHODS: This prospective, randomised, double-blind, two-group, parallel-arm, multicentre, phase 3 comparative study included patients with nAMD ≥ 50 years, randomised (in a 2:1 ratio) in a double-blind manner to receive 0.5 mg (0.05 mL) intravitreal injection of either Sun's ranibizumab or reference ranibizumab in the study eye every 4 weeks until week 16 (total of four doses). RESULTS: Primary endpoint results demonstrated equivalence in the proportion of patients who lost fewer than 15 letters from baseline best-corrected visual acuity (BCVA) to the end of week 16 (99% of patients in Sun's ranibizumab and 100% in reference ranibizumab; p > 0.9999), with the proportional difference (90% confidence interval) at -1% (-2.51, +0.61) lying within a pre-specified equivalence margin. Visual acuity improved by 15 or more letters in 43% of Sun's ranibizumab group and 37% of the reference ranibizumab group (p = 0.4267). The mean increase in BCVA was 15.7 letters in Sun's ranibizumab group and 14.6 letters in the reference ranibizumab group (p < 0.001 within both groups and p = 0.5275 between groups). The mean change in central macular thickness was comparable between groups (p = 0.7946). Anti-ranibizumab antibodies were found in one patient of the reference ranibizumab group, while neutralising antibodies were not found in any patients. Both products were well tolerated. CONCLUSION: Sun's ranibizumab biosimilar is found to be therapeutically equivalent to reference ranibizumab in patients with nAMD. There were no additional safety or immunogenicity concerns.

Clinical safety and pharmacokinetic evaluation of aqueous extract of Cocculus hirsutus, an anti-viral phytopharmacetical drug as a potential for the treatment of dengue and COVID-19.

Background and aim: Dengue a worldwide concern for public health has no effective vaccine or drug available for its prevention or treatment. There are billions of people who are at risk of contracting the dengue virus (DENV) infections with only anti-mosquito strategies to combat this disease. Based on the reports, particularly in vitro studies and small animal studies showing anti-viral activity of aqueous extract of Cocculus hirsutus (AQCH), studies were conducted on AQCH tablets as a potential for the treatment of dengue and COVID-19 infections. The current study was part of the research on AQCH tablet formulation and was aimed to evaluate safety and pharmacokinetics in healthy human subjects. Materials and methods: Sixty healthy adult human subjects were divided into 5 groups (cohorts: I to V; n = 12 per cohort) and randomized in the ratio of 3:1 to receive active treatment or placebo in a blinded manner. Five doses 100 mg, 200 mg, 400 mg, 600 mg and 800 mg tablets were administered three times daily at an interval of 8 h for days 01-09 under fasting conditions and a single dose in morning on day 10. Safety assessment was based on monitoring the occurrence, pattern, intensity, and severity of adverse events during study period. Blood samples were collected for measurement of the bio-active marker Sinococuline concentrations by a validated LC-MS/MS method followed by pharmacokinetic evaluation. Results and conclusion: The test formulation was well tolerated in all cohorts. Sinococuline peak plasma concentration (Cmax) and total exposure of plasma concentration (AUC) demonstrated linearity up to 600 mg and saturation kinetics at 800 mg dose. There was no difference observed in elimination half-life for all the cohorts, suggesting absence of saturation in rate of elimination. Dose accumulation was observed and steady state was achieved within 3 days. The information on human pharmacokinetics of AQCH tablets would assist in further dose optimization with defined pharmacokinetic-pharmacodynamic relationship.

Efficacy and Safety of a Phytopharmaceutical Drug Derived from Cocculus hirsutus in Adults with Moderate COVID-19: a Phase 2, Open-label, Multicenter, Randomized Controlled Trial.

INTRODUCTION: There is an urgent need for an effective, oral therapy for COVID-19. Purified aqueous extract of Cocculus hirsutus (AQCH) has shown robust antiviral activity in in vitro studies. We aimed to evaluate the efficacy and safety of AQCH plus standard of care in hospitalized patients with moderate COVID-19. METHODS: In an open-label, multicenter, randomized controlled trial conducted in India, eligible patients (aged 18-75 years) were randomized (1:1) to receive AQCH 400 mg orally three times a day plus standard of care (AQCH group) or standard of care alone (control group) for 10 days. Primary endpoint was the proportion of patients showing clinical improvement by day 14. Time to clinical improvement, time to viral clearance, and duration of hospitalization were secondary endpoints. RESULTS: A total of 210 patients were randomized. By day 14 most patients in both groups showed clinical improvement [difference - 0.01 (95% CI - 0.07 to 0.05); p = 1.0]. Median time to clinical improvement was 8 days (IQR 8-11) in the AQCH group versus 11 days (IQR 8-11) in the control group [HR 1.27 (95% CI 0.95-1.71); p = 0.032]. Time to viral clearance and duration of hospitalization were also significantly shorter in the AQCH group (p = 0.0002 and p = 0.016, respectively). AQCH was well tolerated, with no safety concerns identified. CONCLUSIONS: AQCH significantly reduced time to clinical improvement, time to viral clearance, and duration of hospitalization. In a pandemic, this has significant potential to decrease healthcare resource utilization and increase hospital bed availability. Further investigation of the therapeutic potential of AQCH in patients with COVID-19 is warranted. TRIAL REGISTRATION: Clinical Trials Registry - India (CTRI/2020/05/025397).

Assessment of topiramate's efficacy and safety in epilepsy.

OBJECTIVE: To study the significance of topiramate (TPM) addition on seizure control in treatment of epilepsy. DESIGN: A prospective open label add-on trial of TPM addition in patients with epilepsy was done. The events of baseline phase of 12 weeks followed by titration and maintenance phases were recorded. Assessment of the number of seizure and emergent adverse effects was done by a monthly visit for each case. MAIN OUTCOME MEASURES: Reduction of more than 50% mean seizure frequency or response ratio of 0.33 was taken as the criteria for responders. STATISTICAL ANALYSIS: Normal Z-test for significance of differences between two proportions and Chi-square test for presence of association was applied and mean age, median duration, sex ratio, percentage prevalence were depicted. RESULTS: Significant responses to TPM in both partial as well as generalized seizures were observed (Z = 6.66, P < 0.001 and Z = 4.185, P < 0.01). The effect was more pronounced in patients with partial seizures. However, the overall response was highly significant (Z = 7.839, P < 0.001). The best response was noted at the dose of 200-300 mg/day (Z = 6.708, P < 0.001). More than 35% cases of partial and generalized seizures reported more than 75% reduction levels. The drug was well tolerated in more than 65% cases for side effects on psychosis, giddiness, and anorexia. Mild side effects were seen only in about less than 35% cases. CONCLUSIONS: TPM was found as a significantly effective add-on anticonvulsant with some limitation or mild side effects.

AIM: To evaluate the efficacy and safety of fixed drug combination (FDC) halometasone 0.05% and fusidic acid 2% (group A) vs FDC betamethasone 0.12% and neomycin sulfate 0.5% cream (group B) in acute or chronic infected eczematous dermatosis, through a randomized open-label, comparative, multicentric study. MATERIALS AND METHODS: A total of 152 patients were randomized to either Group A or Group B. EASI (Eczema Area and Severity Index), IGA (Investigator's global assessment), scale for severity of eczema, pruritus, and safety parameters were assessed at baseline, Day 5/Day 10, Day 10/20, and Day 20/Day 30 for acute/chronic cases. Skin swabs were tested at screening, Day 10, and end of the study. RESULTS: Staphylococcus aureus was the frequently encountered causative agent. There was a significant reduction within the study groups in EASI, IGA scales for severity of eczema, pruritus at various visits, compared to baseline. At the end of study, 83.87% in group A and 65.71% in group B were culture negative. Cure rate was 54.28% and 50% in group A and B, respectively. Five adverse events were reported in five patients, of which three patients withdrew from the study. CONCLUSION: Halometasone 0.05% and Fusidic acid 2% cream is effective, safe, well tolerated with comparable efficacy to the comparator in the treatment of acute and chronic infected eczematous dermatosis.

Efficacy and safety of topical halometasone in eczematous dermatoses in Indian population: an open label, noncomparative study.

BACKGROUND: Topical steroids remain the mainstay of treatment in eczema, an inflammatory skin reaction characterized by pruritus, redness, scaling, and clustered oozing papulovesicles. Halometasone is a new potent corticosteroid approved in the Indian market for topical application in the treatment of dermatitis. AIMS: To evaluate the efficacy and safety of halometasone in the treatment of acute or chronic noninfected eczematous dermatosis in Indian population. MATERIALS AND METHODS: A prospective, open, multicentric, phase 3, noncomparative clinical trial conducted at outpatient departments of seven centres. Two hundred endogenous eczema patients meeting study criteria were enrolled. Halometasone 0.05% cream was applied twice daily for 30 days in chronic and 20 days in acute eczema patients. Calculation of eczema area and severity index, and assessment of investigator's global assessment of severity of eczema and severity of pruritus score were done at each visit and compared with baseline. All adverse events (AE) were captured and documented. Laboratory investigations including haematological tests, urinalysis, renal and liver function tests were performed at baseline and at end of treatment. RESULTS: Of the 200 patients enrolled, 180 were chronic and 20 were acute eczema patients. It was found that there was a significant (P<0.001) improvement in all efficacy parameters compared with baseline. The treatment was shown to be successful in 91% patients. AE were reported in 30 patients and there was no serious AE reported. There was no clinically significant difference in laboratory investigations with treatment. CONCLUSIONS: Halometasone was shown to be safe and very effective in Indian patients with acute and chronic eczema and the drug was well tolerated.
