On April 17, 2025, Venus Remedies Limited, a leading pharmaceutical company specializing in critical care injectables, announced a major milestone in its fight against antibiotic-resistant infections. The company’s investigational product VRP-034, a novel formulation of polymyxin B, has been granted the Qualified Infectious Disease Product (QIDP) designation by the US Food and Drug Administration (FDA). This recognition is a significant step forward in the treatment of bloodstream infections caused by polymyxin B-susceptible strains in adults.

What is VRP-034?

VRP-034 is an advanced supra-molecular cationic (SMC) formulation of polymyxin B sulfate, developed by Venus Remedies’ R&D division, Venus Medicine Research Centre (VMRC). The novel formulation was specifically designed to minimize the nephrotoxic effects associated with conventional polymyxin B therapy, a common issue in patients receiving polymyxin B treatment for multi-drug resistant infections.

Key Benefits of VRP-034

The QIDP designation granted by the US FDA is a testament to the urgent global need for safer and more effective polymyxin-based therapies. This designation, provided under the Generating Antibiotic Incentives Now (GAIN) Act, offers VRP-034 several regulatory advantages, including:

• Priority review of the drug.

• Eligibility for fast track designation.

• An additional five years of market exclusivity upon approval.

Scientific Innovation Behind VRP-034

One of the key features that sets VRP-034 apart from traditional polymyxin B formulations is the use of Venus Remedies’ proprietary Renal Guard technology. This cutting-edge technology, developed through kidney-on-a-chip technology, addresses the kidney injury biomarkers (such as KIM-1, cystatin C, NAG, and NGAL) induced by polymyxin B. The technology has been instrumental in developing a formulation that mitigates the nephrotoxic effects commonly seen in up to 60% of patients treated with conventional polymyxin B.

Preclinical Findings

Several preclinical studies have demonstrated that VRP-034 significantly reduces nephrotoxicity and improves therapeutic outcomes when compared to marketed polymyxin B. Some of the most notable findings include:

• Up to 70% reduction in nephrotoxicity when compared to conventional polymyxin B.

• Robust efficacy against resistant pathogens in both in vitro and animal models.

• Favorable safety profiles across multiple toxicity studies, utilizing advanced renal biomarkers and human organ-on-a-chip models.

A Game Changer in Antimicrobial Resistance

The QIDP recognition for VRP-034 is a pivotal achievement in the company’s ongoing efforts to combat antimicrobial resistance (AMR). With increasing concerns over multi-drug resistant (MDR) infections, especially gram-negative bacteria, polymyxins like polymyxin B and colistin have become crucial last-line antibiotics. However, their use has been severely restricted due to their nephrotoxic effects. VRP-034 offers a promising solution to these challenges, providing a safer and more effective treatment option for bloodstream infections caused by resistant pathogens.

Venus Remedies’ Commitment to Innovation

“We are excited to see VRP-034 granted the QIDP designation by the US FDA, which reflects the critical need for safer polymyxin-based therapies,” said Saranah Chaudhary, CEO of Venus Medicine Research Centre. “This milestone underscores our ongoing commitment to addressing unmet needs in infectious disease therapy, particularly in the battle against antimicrobial resistance.”

The Road Ahead

The QIDP designation sets the stage for VRP-034 to advance rapidly through regulatory processes, offering the potential for early approval and a faster route to market. This breakthrough represents a major step in Venus Remedies’ journey to develop innovative therapies that meet the global demand for safer, more effective treatments for life-threatening infections.

With this designation, Venus Remedies continues to strengthen its commitment to scientific excellence and its dedication to improving public health outcomes through innovation.

As the global fight against antimicrobial resistance intensifies, VRP-034 is positioned to be a significant player in the ongoing effort to develop safer, more effective treatments for bloodstream infections caused by polymyxin B-susceptible pathogens.

Conclusion

In summary, the QIDP designation for VRP-034 is a crucial step forward for Venus Remedies in its mission to deliver cutting-edge solutions for patients suffering from antimicrobial-resistant infections. The company’s dedication to reducing the nephrotoxic effects associated with conventional polymyxin B, while maintaining its therapeutic efficacy, marks a promising new chapter in the fight against antimicrobial resistance.

For further updates, Venus Remedies will continue to provide timely communications about the progress of VRP-034 and its role in improving infectious disease treatment.
