NCT06962631

Brief Summary

This is a multicenter, prospective clinical trial evaluating the efficacy and safety of V-IMMUNE®, a 5% human normal immunoglobulin formulation administered intravenously, for the treatment of immune thrombocytopenia (ITP) in patients aged ≥1 year. The primary objective is to assess the proportion of patients achieving a platelet count ≥50,000/mm³ on or before Day 9 following the first infusion. The trial employs a single-group design, comparing outcomes to historical controls derived from the literature. Eligible patients must have a confirmed diagnosis of ITP with a platelet count ≤20,000/mm³ and no concurrent conditions likely to cause thrombocytopenia. Key exclusions include non-immune thrombocytopenia, active sepsis, pregnancy or lactation, hypersensitivity to blood products or IgG preparations, and various significant comorbidities (e.g., uncontrolled hypertension, severe hepatic or renal impairment, recent rituximab use). The intervention consists of V-IMMUNE® at a dose of 1 g/kg, administered once daily for two consecutive days, with infusion rates titrated from 0.01 mL/kg/min to 0.06 mL/kg/min. Standard pre-medication protocols (IV normal saline and diphenhydramine) are administered to mitigate infusion-related reactions and reduce the risk of thromboembolic events. Patients will be monitored at multiple time points from baseline through Day 90, with primary efficacy evaluation at Day 9. Secondary endpoints include duration of platelet response, overall treatment response rate, bleeding events, and incidence of infusion-related adverse events.

Outcome Measures

Primary Outcomes (1)

  • Proportion of patients achieving a platelet count ≥50,000/mm³ on or before Day 9 following the first infusion

    Evaluate the efficacy of V-IMMUNE® in raising the platelet count of individuals with immune thrombocytopenia to a threshold of 50,000/mm³ or greater by or before Day 9 following the first dose. The proportion will be the ratio between the number of patients who achieved platelet count ≥ 50,000/mm3 / total of patients who received at least one dose of V-Immune® and had laboratory assessments performed at least once during the scheduled visits within 9 days.

    9 days

Secondary Outcomes (7)

  • Therapeutic response defined as the increase in platelets count

    9 days

  • Bleeding occurrence classified according to CTCAE version 5.0

    30 days

  • Number of days with platelets count ≥ 50,000/mm3

    90 days

  • Proportion of infusions during which one or more adverse events (AEs) occurred

    72 hours

  • Total number of adverse events infusion related during the whole study

    30 days

  • +2 more secondary outcomes

Study Arms (1)

Intervention arm

EXPERIMENTAL

Intervention arm will receive a human normal immunoglobulin to be administered intravenously, once daily for 2 consecutive days (Day 1 and Day 2). If the platelet count is not maintained for the desired duration after the first immunoglobin infusion, and at the discretion of the investigator and the patient/legal representative, participants may receive up to one additional cycle between Day 15 and Day 30 Pre-Medication Rapid IV infusion of 500 mL of 0.9% saline, 50 mg of diphenhydramine IV followed by saline 0.9% slow infusion Pediatrics, before the infusion of PSI, an IV infusion of 0.9% sodium chloride (normal saline) at 10 mL/kg over 1 hour, up to a maximum volume of 500 mL, will be administered, along with diphenhydramine 1.25 mg/kg IV, up to a maximum dose of 50 mg. At the end of the V IMMUNE® infusion, administer 0.9% sodium chloride IV at 10 mL/kg, up to a maximum of 500 mL, at an infusion rate of 10 mL/kg, to maintain a patent venous access for at least 30 to 40 minutes.

Biological: 5% (5g/100 ml) intravenous immunoglobin

Interventions

A 5% human normal immunoglobulin I.P. (5 g/100 mL) V-IMMUNE® will be administered at a dose of 1 g/kg, intravenously, once daily for 2 consecutive days (Day 1 and Day 2). The infusion rate starts at 0.01 mL/kg/min during the first 30 minutes and is gradually increased up to 0.06 mL/kg/min if no adverse events occur. This will constitute the first cycle of V-IMMUNE® treatment. The dose of 1 g/kg/day on 2 consecutive days is consistent with recommendations for the use of other IVIG products in Immune Thrombocytopenia. If the platelet count is not maintained for the desired duration after the first V-IMMUNE® cycle, and at the discretion of the investigator and the patient/legal representative, participants may receive up to one additional cycle of V-IMMUNE®-at the same dosing regimen used in Cycle 1-between Day 15 and Day 30 Pre-medication before infusion : IV rapidly infusion of 0.9% normal saline 500 mL, or 10 ml/kg pediatrics and diphenhydramine 50 mg IV or 1.25 mg/kg IV (pediatrics)

Data Sharing

IPD Sharing
Will not share

Due to the regulatory nature of this clinical trial-specifically aimed at obtaining market authorization for V-IMMUNE® in Brazil for patients with immune thrombocytopenia-we will not be able to share individual participant data (IPD) outside of the study team. All participant information is considered proprietary and confidential as part of the registration dossier being submitted to the Brazilian health authority. The study protocol, data collection, and analyses must remain under restricted access to fulfill legal, regulatory, and institutional requirements, which include protecting patient privacy and maintaining data integrity for the product's approval process. Consequently, no external IPD sharing is planned at this time.
