1. What is Pepaxti and how is it used
Pepaxti belongs to a group of cancer medications called alkylating agents. It works by binding to DNA (the genetic instruction necessary for cells to survive and multiply) and damaging it, thus helping to stop the growth of cancer cells.
Pepaxti is administered with the steroid dexamethasone to treat adults with multiple myeloma, a type of blood cancer. It is used when the disease does not respond to at least three types of cancer medications. If you have been treated with a stem cell blood transplant (a procedure in which the cells that produce blood are removed and replaced), the time until the reappearance of multiple myeloma after the transplant must be at least 3 years.
2. What you need to know before starting to use Pepaxti
Do not use Pepaxti
- if you are allergic to melfalan flufenamida or any of the other components of this medication (listed in section 6);
- if you are breastfeeding.
Warnings and precautions
Consult your doctor or nurse before Pepaxti is administered to you.
Bleeding and abnormal bruising and low platelet count (blood cells)
Pepaxti may reduce the number of blood cells called platelets, which help the blood to clot. Inform your doctor or nurse immediately if you start bleeding, for example, if you experience nasal bleeding or observe bruises on the skin.
Fever and low white blood cell count
Pepaxti may reduce the number of white blood cells, which are important for fighting infections. Inform your doctor or nurse immediately if you have symptoms of infection, such as fever, chills, or cough.
Low red blood cell count
Pepaxti may reduce the number of red blood cells, which transport oxygen to the cells of your body. Your doctor will take blood samples periodically to monitor your blood cells. Inform your doctor or nurse immediately if you feel weak or tired, if you look pale or if you feel short of breath.
Infections
Infections such as pneumonia and upper respiratory tract infections (which cause symptoms similar to the common cold) are very common with Pepaxti. Inform your doctor or nurse immediately if you present fever or other signs of infection. Your doctor may recommend preventive antibiotics to reduce the risk of developing infections.
Risk of diarrhea, nausea, or vomiting
Inform your doctor if you experience diarrhea, nausea, or vomiting.
Risk of blood clots
The use of Pepaxti in combination with dexamethasone may increase the risk of blood clots. Inform your doctor or nurse if you have ever had a blood clot in a vein (thrombosis). Inform your doctor or nurse immediately if you experience swelling of a leg or arm, if you find it harder to breathe, or if you experience chest pain.
Risk of additional cancer
It is essential to note that patients with multiple myeloma treated with Pepaxti may develop other types of cancer, so your doctor must carefully evaluate the benefits and risks for you when prescribing this medication.
Renal disease
If you have reduced renal function, the adverse effects of Pepaxti on your blood cells may be worse. There is very little information available on the use of the medication in patients with severe renal failure, so it is not possible to recommend a safe and effective dose.
Vaccinations
Live attenuated vaccines (such as vaccines against measles, mumps, and rubella) should not be used during treatment with Pepaxti, as they may cause infection. However, other types of vaccines, such as inactivated vaccines or mRNA-based vaccines, may be used. Inform your healthcare professional that you are being treated with Pepaxti before being vaccinated.
Children and adolescents
Pepaxti is not indicated for children or adolescents under 18 years old.
Other medications and Pepaxti
Inform your doctor if you are taking, have taken recently, or may need to take any other medication.
Pregnancy, breastfeeding, and fertility
If you are pregnant or breastfeeding, or if you think you may be pregnant, consult your doctor before using this medication.
Pregnancy
This medication should not be used during pregnancy unless it is clearly necessary. Avoid becoming pregnant while being treated with this medication, as it may harm the fetus. Your doctor will explain the possible risks of using Pepaxti during pregnancy.
If you are a woman who may become pregnant:
- Your doctor will ask you to undergo a pregnancy test before starting treatment with Pepaxti.
- You must use an effective contraceptive method during treatment and for 6 months after the last dose of Pepaxti. Consult your doctor about effective contraceptive methods that may be suitable for you.
If you are a man who may father a child:
- You must use an effective contraceptive method during treatment and for 6 months after the last dose of Pepaxti.
Breastfeeding
You should not breastfeed during treatment with Pepaxti, as it may be harmful to your baby.
Fertility
Pepaxti may affect the ovaries or sperm, leading to infertility (inability to have children). Women may experience menstrual interruption. In men, permanent inability to father a child (sterility) due to a lack of sperm may occur. Consult your doctor about sperm conservation before treatment.
Driving and operating machinery
Pepaxti may cause nausea and dizziness, which may reduce your ability to drive or operate machinery.
3. How to Use Pepaxti
Pepaxti is prepared in a solution and will be administered by your doctor or nurse through intravenous infusion over 30 minutes. Your doctor will decide on the correct dose of Pepaxti. The recommended initial dose is 40 mg once every 4 weeks. If you weigh 60 kg or less, the recommended initial dose is 30 mg once every 4 weeks. Treatment will continue as long as it is beneficial and you do not experience unacceptable side effects. As part of your treatment, you will also take another medication, dexametasona, orally.
If you receive more Pepaxti than you should
This medication will be administered by your doctor or nurse. In the unlikely event that you are given too much (an overdose), your doctor will examine you, which may include taking blood samples to monitor your blood cells.
If you forget a dose of Pepaxti
It is very important that you attend all your appointments to ensure that your treatment is working. If you miss an appointment, contact your doctor or hospital as soon as possible.

Description of the volume | Pepaxti dose | |||
40 mg (2 vials) | 30 mg (1.5 vials) | 20 mg (1 vial) | 15 mg (0.75 vial) | |
Volume of reconstituted Pepaxti solution required for the final product | 80 ml | 60 ml | 40ml | 30 ml |
Total final volume of the infusion bag after dilution | 250 ml | 230 ml | 210 ml | 200 ml |
Concentration of Pepaxti after dilution | 0.16 mg/ml | 0.13 mg/ml | 0.10 mg/ml | 0.08 mg/ml |
Preparation steps
Read the complete instructions before starting preparation.
Steps 3 to 5 must be completed within 30 minutes.
Reconstitution and dilution steps | ||||||||
Step 1 Determine the number of vials required for the dose according to Table 1 "Volumes of dilution by Pepaxti dose". Place the vial(s) at room temperature for at least 30 minutes. | ||||||||
Step 2 Agitate vigorously the vial or agitate in a vortex to disintegrate the lyophilized powder cake into a loose powder. | ||||||||
Steps 3 to 5 must be performed within a 30-minute timeframe | ||||||||
Third stage
Ensure that the 5% glucose injectable solution is at room temperature (between 20°C and 25°C). Agitate the vial or vials vigorously until the solution is transparent. Leave the vial(s) to allow air bubbles to dissipate and confirm that a transparent solution has been obtained. | ||||||||
Step 4 Extract 80 ml from a refrigerated (between 2°C and 8°C) 250 ml bag of 0.9% sodium chloride injectable solution. Discard the 80 ml extracted. | ||||||||
Step 5
Discard any unused portion remaining in the vial or vials. Invert the bag gently to mix the solution. Do not agitate. Check that the solution is transparent and colorless, or pale yellow. Do not use if the solution is decolorized or contains particles. |
Shelf life
Pepaxti degrades in the solution, especially at room temperature, and the dilution solution shelf life should not be exceeded.
For immediate administration |
The infusion of the diluted solution must beginwithin 60 minutesafter the start of reconstitution (step 3). |
For delayed administration |
If not used for immediate administration, the diluted solution must be stored in a refrigerator (between 2°C and 8°C) within 30 minutes after the initial reconstitution (step 3) and kept fora maximum of 6 hours. |
Administration
Before administration, parenteral medications must be visually inspected for the presence of particles and color changes. Do not use if particles are visibly opaque, decolorized, or foreign particles are observed.
Administration steps |
Step 6 Administer Pepaxti as a 30-minute intravenous infusion through a peripheral venous access or a central venous access device, for example, a PICC or a tunneled central venous catheter. If the infusion bag has been stored in the refrigerator, allow it to reach room temperature (between 20°C and 25°C). Initiate the infusion within 30 minutes after removing the diluted solution from the refrigerator. |
Step 7 Once the Pepaxti infusion is completed, wash the central catheter with a 0.9% sodium chloride injectable solution. |
Elimination
Pepaxti is a cytotoxic medication for single use. Follow the procedure for safe handling and disposal of mustard nitrogen analogs by healthcare professionals or medical personnel and comply with current guidelines for cytotoxic medications. The disposal of unused medication and all materials that have come into contact with it will be carried out in accordance with local regulations.
