What is REZZAYO

REZZAYO contains the active ingredient rezafungin, which is an antifungal. Rezafungin belongs to a group of medicines called echinocandins.

What is REZZAYO used for

This medicine is administered to adults to treat invasive candidiasis, a severe fungal infection in tissues or organs caused by a type of yeast calledCandida.

How REZZAYO works

This medicine blocks the action of an enzyme (a type of protein) that fungal cells need to produce a molecule that strengthens their cell walls. Thismakes fungal cells fragile and prevents the growth of the fungus. This prevents the infection from spreading and gives the body's natural defenses the opportunity to eliminate the infection.

You should not be givenREZZAYO

• if you are allergic to rezafungina, other echinocandins (such as caspofungin, anidulafungin), or any of the other components of this medication (listed in section6).

Warnings and precautions

Consult your doctor, pharmacist, or nurse before receiving REZZAYO.

Liver effects

Your doctor may decide to closely monitor your liver function if you develop liver problems during treatment.

Perfusion-related reactions

REZZAYO may cause perfusion-related reactions, which could include skin redness (rubefaction), feeling of heat, nausea (feeling of discomfort), and chest tightness. Your doctor may decide to monitor you during perfusion to detect signs of a perfusion-related reaction. Your doctor may decide to slow down the infusion (drip) if a perfusion-related reaction occurs.

Sensitivity to light

REZZAYO may increase the risk of phototoxicity (a disorder in which the skin and eyes become very sensitive to sunlight or other types of light). During treatment and for 7days after receiving the last dose of this medication, you should avoid exposure to the sun or use artificial tanning lamps without protection (such as sunscreen).

REZZAYO should be administered once a week, via intravenous infusion (drip). The infusion will last at least 1 hour. Your doctor will determine the duration of the infusion and may increase it up to 3 hours to prevent infusion-related reactions.

Your doctor will determine how long you should receive treatment based on your response to the medication and your condition.

------------------------------------------------------------------------------------------------------------------------

This information is intended solely for healthcare professionals:

REZZAYO should be administered as a single drug by intravenous infusion in a sodium chloride 9 mg/ml (0.9%) injection solution, sodium chloride 4.5 mg/ml (0.45%) injection solution, or 5% glucose injection solution.

INSTRUCTIONS FOR USE IN ADULT PATIENTS

REZZAYO should be reconstituted and diluted before administration.

From a microbiological point of view, the reconstituted solution and the diluted infusion solution should be used immediately. If not used immediately, the storage conditions before use are the responsibility of the user and will normally not exceed 24 hours between 2 and 8°C from the first opening, unless the reconstitution and dilution have been performed in controlled and validated aseptic conditions.

Using aseptic techniques, reconstitute each vial with 9.5 ml of injection water. The concentration of the reconstituted vial will be 20 mg/ml. Do not use sodium chloride 9 mg/ml (0.9%) injection solution to reconstitute the vial, use only injection water.

To minimize foam formation, do not shake or mix vigorously. The white to pale yellow powder will dissolve completely. Mix gently with circular movements for a maximum of 5 minutes until the reconstituted solution is a transparent, colorless to pale yellow solution. The reconstituted solution should be visually inspected for particles or color changes. If irregularities are detected, do not use the vial.

The vial is for single use only. Therefore, the reconstituted concentrate not used should be discarded immediately.

To administer the loading dose of 400 mg, the reconstitution step should be repeated for the additional vial of REZZAYO (see dosage table).

The total infusion volume should be 250 ml; therefore, the volume of the infusion bag (or bottle) should be adjusted accordingly, as shown in the dosage table.Aspirate aseptically 10 ml from each of the reconstituted vials into an infusion bag (or bottle) containing sodium chloride 9 mg/ml (0.9%) injection solution, sodium chloride 4.5 mg/ml (0.45%) injection solution, or 5% glucose injection solution.The total reconstituted volume to be added to the infusion bag (or bottle) is indicated in the dosage table.Mix the solution by gently inverting the infusion bag (or bottle). Avoid excessive agitation.

After dilution, the solution should be discarded if particles or color changes are identified.

TABLE OF DOSAGE: PREPARATION OF INFUSION SOLUTION IN ADULTS
