A Multicentric, Prospective, Observational, Single-Arm Registry Study to Assess the Clinical Safety and Effectiveness of Thrombophob Ointment (Heparin Sodium + Benzyl Nicotinate) in Indian Patients With Thrombophlebitis.

Purpose Thrombophlebitis is a frequent intravenous (IV) therapy consequence. Topical heparin for seven days is used as a treatment for thrombophlebitis. This study was performed to evaluate the clinical safety and effectiveness of the combination of heparin sodium & benzyl nicotinate (Thrombophob Ointment, manufactured by Zydus Healthcare Ltd., Ahmedabad, India) in thrombophlebitis patients in India. Methods A study carried out by 118 Indian doctors examined 2002 thrombophlebitis patients from 2016-2023, prescribing ointment containing heparin sodium and benzyl nicotinate. Patients were followed up on day three and day seven after starting the treatment, and safety and effectiveness were recorded, including adverse events. Result A total of 2002 patients were included in the study and males were predominant (58.15%). IV fluids (60.58%) were the leading cause of thrombophlebitis. The study found notable improvements in key markers of venous health over time. Compared to baseline, patients experienced significantly reduced severity of phlebitis, shorter venous lesion lengths, and lower pain and tenderness scores by both day 3 and day 7 (p<0.001 for all comparisons). Furthermore, these improvements continued between day 3 and day 7, indicating sustained positive effects (p<0.001 for all comparisons). After the application of the ointment, very few patients experienced adverse effects (0.25% on day three and 0.05% on day seven). Treatment effectiveness was excellent in 72% of patients, and treatment safety was excellent in 93% of patients. Conclusion The ointment containing heparin sodium and benzyl nicotinate was well tolerated and efficacious in the treatment of thrombophlebitis in Indian patients.

Efficacy and safety of Once-Daily Vilanterol/Fluticasone furoate MDI in persistent asthma: Phase 3 OD-INHALE Study.

INTRODUCTION: Once-daily inhalers have been shown to improve adherence leading to lesser discontinuation compared to twice- or thrice-daily inhalers in management of asthma. Combination of Vilanterol and Fluticasone Furoate (VI/FF) is approved for management of asthma and COPD and is available as a dry powder inhaler. Pressurized-Metered Dose Inhalers (pMDIs) offer ease-of-use and therapy alternatives for patients with low inspiratory flow. This study assessed the efficacy and safety of a new once-daily pMDI containing VI/FF in individuals diagnosed with persistent asthma. METHODS: This phase 3, double-blind, randomized controlled study assessed the non-inferiority of VI/FF (12.5 mcg/50 mcg & 12.5 mcg/100 mcg; 2 puffs once-daily) over Formoterol Fumarate and Fluticasone Propionate (FOR/FP, 6 mcg/125 mcg & 6 mcg/250 mcg; 2 puffs twice-daily) in patients with persistent asthma. Primary outcome was change from baseline in trough FEV1 at the end of study (12 weeks). Adverse events and number of exacerbations were used to evaluate safety. RESULTS: A total of 330 patients were randomized into VI/FF (165) and FOR/FP (165). Trough FEV1 significantly improved in both the groups at week 12, with a mean difference (VI/FF minus FOR/FP) being 54.75 mL (95% CI, 8.42-101.08 mL, p = 0.02). The low dose VI/FF had similar efficacy to that of low dose FOR/FP and high dose VI/FF had similar efficacy to high dose FOR/FP. No serious adverse events were reported during the study. CONCLUSION: Once daily VI/FF pMDI was non-inferior to twice daily FOR/FP pMDI in patients with persistent asthma.

Long-term Persistence of Immunogenicity After Primary Vaccination and Response to Booster Vaccination With Typhoid Conjugate Vaccine: Results of a Phase IV Extension Study.

OBJECTIVE: To evaluate the persistence of antibodies three years after primary vaccination with typhoid conjugate vaccine (TCV) of either Cadila Healthcare Ltd. (Cadila-TCV) or Bharat Biotech International Ltd. (Bharat-TCV) administered in a previous phase II/III study, and to study the booster dose response to Cadila-TCV. METHODS: This was an open-label, phase IV extension study conducted in tertiary care and multispecialty hospitals in India. 112 subjects (Cadila-TCV-57, Bharat-TCV-55) who had participated in previous study were enrolled. Of these, eligible subjects received a single-dose of Cadila-TCV and were followed-up for 28 days post-booster. Primary outcome was persistence of antibodies 3 years after primary vaccination and seroconversion (≥4-fold rise in antibody titre from baseline) 28 days post-booster. Safety was based on reported adverse events (AEs) post-booster. RESULTS: The baseline GMT reported in the current study was significantly higher than pre-vaccination GMT reported in the previous study. 89/112 (79.5%) subjects had antibody titer ≥10 IU/mL at baseline; eligible subjects (n=17) who had baseline antibody titre <10 IU/mL were administered booster dose. All the vaccinated subjects showed seroconversion post-booster. The GMTs reported at 10 days and 28 days post-booster were significantly higher as compared to GMTs reported after primary vaccination in previous study. 4 (23.5%) vaccinated subjects reported 9 AEs; all were solicited and of mild/moderate intensity. CONCLUSIONS: There was a significant persistence of immunogenicity after primary vaccination with both the TCVs, and robust immune response after booster vaccination with Cadila-TCV.

Immunogenicity and Safety of Typhoid Conjugate Vaccine in Healthy Indian Subjects: A Randomized, Active-controlled, Comparative Clinical Trial.

OBJECTIVE: To compare the immunogenicity and safety of an investigational typhoid Vi conjugate vaccine (Test TCV) with a marketed typhoid Vi conjugate vaccine (Comparator TCV). DESIGN: Randomized, controlled trial. SETTING: Tertiary care and multispecialty hospitals. PARTICIPANTS: 240 healthy subjects of 6 months to 45 years. Pediatric (<18 years) subjects were enrolled after day 21 safety assessment of adult subjects. INTERVENTION: Participants received a single-dose of test TCV or comparator TCV at baseline and were followed up for 6 weeks post-vaccination. MAIN OUTCOME MEASURE: Primary variable was to demonstrate non-inferiority of the test TCV with the comparator TCV for seroconversion post-vaccination (³4-fold rise in antibody titre). Secondary variables were seroconversion in the adult and pediatric cohorts, and geometric mean titre of antibodies while the safety was based on reported adverse events. RESULTS: A total of 117 subjects (Adult-58, Pediatric-59) and 119 subjects (Adult-60, Pediatric-59) in test and comparator group, respectively completed the study. The seroconversion rate with test TCV (overall-94.8%, adult-96.6% and pediatric-93.1%) was non-inferior to comparator TCV (overall-91.6%, adult-91.7% and pediatric-91.5%). The geometric mean titres of antibodies (EU/mL) at baseline (test TCV: overall-7.6, adult-10.0, and pediatric-5.7; and comparator TCV: overall-8.0, adult-12.0, and pediatric-5.3) and at end of study (test TCV: overall-1121.0, adult-1411.0 and pediatric-891.1; and comparator TCV: overall-1104.0, adult-1199.0 and pediatric-1014.0) were also comparable between the groups (P>0.05 for all). The most common adverse event was injection-site pain followed by fever in both the groups. CONCLUSIONS: The immunogenicity and safety of test TCV is comparable to already marketed comparator TCV.
