Why Use a CSTD When Handling Monoclonal Antibodies?

Monoclonal antibodies (mAbs) are used across oncology, autoimmune diseases, inflammatory conditions and other therapeutic areas. As their use expands, healthcare facilities should establish appropriate procedures for their preparation and administration.

Safe handling of these potentially hazardous yet lifesaving drugs has two key dimensions: minimizing potential occupational exposure while maintaining sterility of the medication throughout preparation and administration.

Monoclonal antibodies (mAbs) are targeted biological therapies. Their highly focused mechanisms of action have made them valuable therapeutic tools. However, not all mAbs present the same occupational risk for healthcare professionals.

Certain mAbs, including antibody-drug conjugates and other products classified as hazardous, require additional precautions during preparation and administration.

The long-term consequences of repeated occupational exposure to some of these agents are not yet fully understood. Healthcare facilities should therefore assess the risks associated with specific drugs and implement appropriate protective measures in accordance relevant guidance, including NIOSH recommendations for hazardous-drug handling.

Protecting healthcare professionals from exposure is only one aspect of safe handling.

Maintaining medication sterility is equally important. Preparation may involve multiple connections and transfers between vials, syringes, IV bags and administration components. Each manipulation creates a point at which the integrity of the closed pathway must be maintained.

This is particularly important in oncology settings, where patients may be immunocompromised and microbial contamination can have serious consequences. An effective handling system should protect healthcare professionals from the drug while protecting the drug from environmental contamination.

A Closed System Drug Transfer Device (CSTD) is designed to mechanically prohibit the transfer of environmental contaminants into the system and the escape of hazardous drug or vapor concentrations outside it.

When handling hazardous mAbs, CSTDs can add a layer of protection during preparation and administration by helping to:

• Minimize potential occupational exposure
• Contain hazardous drug vapors, aerosols and droplets
• Reduce leaks, spills and environmental contamination
• Support the maintenance of sterility during drug transfer
  

CSTDs complement, rather than replace, engineering controls, personal protective equipment, aseptic technique, staff training and institutional procedures.

Safe handling does not end when a drug leaves the pharmacy. Healthcare professionals may encounter hazardous drugs throughout preparation and administration, making it important to maintain a closed pathway across the process.

Chemfort® is a CSTD designed to support working with hazardous drugs safely. Its Vial Adaptor incorporates patented ToxiGuard® technology, which combines two protective elements:

Drug-binding matrix mechanical barrier: the drug-binding matrix physically traps hazardous drug molecules, helping prevent the release of drug vapors, aerosols and droplets into the surrounding environment.

0.2 μm membrane: a hydrophobic and oleophobic 0.2 μm membrane blocks airborne contaminants, supporting the maintenance of sterility within the drug transfer system.

Together, these elements are designed to lock hazardous drugs in, while locking airborne environmental contaminants out.

Chemfort® uses just 3 SKUs to provide safe and closed connections for 90% of hazardous drug protocols without unnecessary complexity. Universal luer-lock compatibility enables integration with commonly used syringes, IV bags and infusion components.

As mAb therapies evolve, healthcare facilities must evaluate how drugs requiring hazardous drug precautions are prepared and administered. CSTDs can provide an additional layer of protection, addressing occupational exposure while helping preserve medication sterility.

Chemfort® combines hazardous-drug containment and sterility protection in a brilliantly simple and user friendly closed transfer system designed for clinical workflows.

Chemfort® protects healthcare professionals, maintains sterility and protects the patient.

CSTDs help protect healthcare professionals from potential exposure to hazardous monoclonal antibodies (mAbs) during drug preparation and administration. They are designed to prevent hazardous drugs from escaping the transfer system while limiting the entry of environmental contaminants, supporting both occupational safety and medication sterility. This is important for healthcare professional safety because there is currently insufficient data in the literature on the long term effects of mAbs.

Healthcare professionals may be exposed to hazardous monoclonal antibodies (mAbs) through accidental spills, droplets, aerosols, or contaminated surfaces. Exposure can occur during drug transfers between vials, syringes, IV bags, and administration components. Appropriate handling procedures and protective equipment help minimize these risks.

CSTDs are designed to mechanically prevent environmental contaminants from entering the drug transfer system. By maintaining a closed pathway during preparation and administration, they help reduce contamination risks and support medication sterility. CSTDs complement, rather than replace, aseptic technique and established infection-control procedures.

Chemfort® uses ToxiGuard® technology, which combines a patented drug binding matrix mechanical barrier that physically captures hazardous drug molecules and a 0.2 μm membrane that blocks airborne environmental contaminants. Together, these elements help contain hazardous drugs while supporting sterility during preparation and administration. Chemfort®’s membrane to membrane connections help maintain a closed drug path between system components to prevent hazardous drug leakage.
