A Proactive Approach to Improved Blood Safety
No matter where you are located, increased travel, climate change, evolving pathogens, emerging pandemics and the need to advance healthcare practices have put global blood safety at the forefront of industry focus.
With all this change, it’s time to take a proactive approach to protecting patients from the potential dangers of donated blood. The Mirasol PRT system can help you do it by reducing the pathogen load of a broad range of disease-causing viruses, bacteria and parasites. The system also inactivates residual white blood cells found in blood components,1,2,3 which may help to reduce transfusion reactions in patients.
Powerful, Proven and So Much Potential
The Mirasol PRT system is the only PRT system shown in a human clinical trial to reduce the transfusion-transmitted infection (TTI) of a disease, reducing TTI of malaria by 87%.4
The Right Balance for Better Blood
We believe better blood safety should provide the right balance of efficacy and ease of use while maintaining the quality of blood components for patients who need them. The Mirasol PRT system is a simple system that has the power to deliver better patient care, reducing the risks associated with the lifesaving gift of blood.
The Mirasol PRT System
You know better than anyone—these are challenging times. The Mirasol PRT system allows you to meet the needs of your business by optimizing the balance of cost, efficacy and safety of your blood products.5,6
Safety
Mirasol PRT provides an added layer of protection against tested pathogens (HIV, HBV, HCV) during the window period7 as well as against untested/emerging pathogens. It uses a combination of riboflavin (vitamin B2), a nontoxic and nonmutagenic substance,8 and UV light.
Mirasol reduces the pathogen load of a broad range of disease-causing viruses, bacteria and parasites and inactivates residual white blood cells in blood products.1,2,3 For example:

Affordability
The routine use of Mirasol may replace bacterial testing,11 gamma irradiation18 and cytomegalovirus (CMV) screening (if leukoreduction is used)1,2,3 and may reduce the expired product discard rate (based on a 7-day shelf life for platelets in PAS).15 Operational practices may vary by center.

There is no compound removal step17 in the Mirasol process. That means you can expect these benefits as compared with other pathogen reduction technologies:
- Minimal platelet loss, less than < 5% for both apheresis- and WB-derived buffy coat platelets19,20,21
- Avoid extra platelet agitators
- Avoid the potential need to manage two different inventories of blood products (one for the compound removal step and one for storage)

Peace of Mind
With Mirasol, there are no known contraindications for use1,2,3 and no acute/long-term effects for patients, including pediatrics,22,23 because riboflavin and its photoproducts are nontoxic and nonmutagenic.8
For processing staff, there are no additional health hazard risks or precautions required for product handling24 because there is no need to remove the chemical compound.17

How It Works
The Right Path to Advancing Blood Safety: Safety, Simplicity, Affordability, Peace of Mind
The Mirasol PRT system uses a combination of nontoxic, nonmutagenic riboflavin (vitamin B2) and a specific spectrum of ultraviolet (UV) light to inactivate viruses, bacteria, parasites and white blood cells that may be present in collected blood products.
The Mirasol PRT system consists of three main components:
- A disposable kit — includes an illumination/storage bag and sterile riboflavin solution
- The Mirasol Illuminator — provides UV light and agitation for the Mirasol treatment
- Mirasol Manager software — integrates and manages data reporting and storage
During treatment, a blood product is mixed with the riboflavin solution and placed into the Illuminator, where it is exposed to UV light. There is no need to remove riboflavin or its photoproducts; after illumination, the treated products are ready for transfusion or placement into storage.
Mode of Action
The Mirasol PRT system causes irreversible changes to the RNA and DNA of viruses, bacteria, parasites and white blood cells, preventing them from replicating and causing disease.
Riboflavin + UV light = irreversible inactivation of pathogens and white blood cellsVideo: Mirasol Mode of Action
The Mirasol PRT system uses a combination of riboflavin (vitamin B2), a non-toxic, non-mutagenic compound, and a specific spectrum of ultraviolet (UV) light to inactivate viruses, bacteria, parasites and white blood cells that may be present in collected blood products.

Clinical Study: IPTAS
The Italian Platelet Technology Assessment Study (IPTAS) was designed as two independent, randomized controlled trials (RCTs) conducted simultaneously in six hematological centers in Italy to assess the effectiveness and safety of pathogen-reduced versus non-pathogen-reduced platelets. Although conclusions on non-inferiority could not be drawn due to low statistical power, the study provides additional information on the safety and efficacy of pathogen-reduced platelets treated with two commercial pathogen-reduction technologies.
