CHAPTER: INTRODUCTION TO USING COSELA
Jennifer Webster (00:09):
Hello, I'm Jennifer Webster. And I've been an oncology nurse for more than 30 years.
In this video, you'll be introduced to COSELA. You'll learn about the dosing, preparation, and administration of COSELA, including managing infusion-site reactions and scheduling delays.
COSELA is indicated to decrease the incidence of chemotherapy-induced myelosuppression in adult patients when administered prior to a platinum/etoposide-containing regimen, or topotecan-containing regimen, for extensive-stage small cell lung cancer (ES-SCLC).
COSELA is contraindicated in patients with a history of serious hypersensitivity reactions to COSELA.
CHAPTER: INTRODUCING MYELOPROTECTION
Jennifer Webster (00:53):
COSELA helps protect hematopoietic stem and progenitor cells from damage due to chemotherapy and helps protect patients against multiple myelosuppressive consequences.
COSELA is the first and only therapy to proactively protect against chemotherapy-induced myelosuppression.
We call this myeloprotection, a proactive approach to help protect the source of multiple blood cell lineages during chemotherapy.
COSELA is given before chemotherapy. You can help reduce the risk of myelosuppression by administering COSELA as a 30-minute intravenous infusion completed within 4 hours prior to the start of chemotherapy on each day chemotherapy is administered.
Each single-dose vial for reconstitution contains 300 mg of COSELA as a sterile, preservative-free, yellow, lyophilized cake.
The recommended dose of COSELA is 240 mg/m2 administered as a 30-minute intravenous infusion completed within 4 hours prior to the start of chemotherapy on each day chemotherapy is administered.
This would be 3 consecutive days within a 21-day cycle for etoposide/platinum-containing regimens or 5 consecutive days within a 21-day cycle for topotecan-containing regimens.
The interval between doses of COSELA on sequential days should not be greater than 28 hours.
Jennifer Webster (02:33):
It's important to note that COSELA is a myeloprotection therapy, not a chemotherapy. COSELA, given per recommended dosing, helps protect hematopoietic stem and progenitor cells (HSPCs) from damage due to chemotherapy. Next, you'll learn how COSELA is prepared for administration.
CHAPTER: PREPARING COSELA
COSELA vials should be stored at controlled room temperature, 68 to 77 degrees Fahrenheit.
COSELA must be reconstituted and then diluted further before giving the IV infusion. Use aseptic technique for reconstitution and dilution.
Be sure to thoroughly inspect the vial and package for any defects or contaminants before administration. This includes checking for things such as particulate matter or discoloration.
Do not use the vial if you suspect any type of contamination.
Reconstitute each 300-mg vial with 19.5 mL of 0.9% Sodium Chloride Injection, or 5% Dextrose Injection, using a sterile syringe to obtain a concentration of 15 mg/mL of COSELA.
Gently swirl the vial contents for up to 3 minutes until it is completely dissolved. Do not shake.
Inspect the reconstituted solution for discoloration and particulate matter.
Reconstituted COSELA solution should be a clear yellow solution.
Do not use if the reconstituted solution is discolored, cloudy, or contains visible particulates.
If needed, you may store the reconstituted solution in the vial at room temperature for up to 4 hours before transferring it to the infusion bag.
Do not refrigerate or freeze and discard any unused portion after use.
To dilute reconstituted COSELA, withdraw the required volume from the vial of reconstituted COSELA solution and dilute into an IV bag containing 0.9% Sodium Chloride Injection or 5% Dextrose Injection.
Mix the diluted solution by gentle inversion. Do not shake.
The final concentration of the diluted COSELA solution should be between 0.5 mg/mL, and 3 mg/mL.
Once again, the diluted COSELA in the IV bag should be a clear yellow solution.
Now let's take a look at how bag and diluent choices affect diluted COSELA storage durations.
If using PVC bags, EVA bags, PO bags, or PO/PA IV bags, you may use 5% Dextrose as the diluent. These combinations can be stored up to 12 hours at room temperature.
PVC, EVA, or PO IV bags can be diluted with 0.9% Sodium Chloride—normal saline. These combinations can be stored up to 8 hours at room temperature.
PO/PA IV bags can also be diluted with normal saline. This combination can be stored up to 4 hours at room temperature.
CHAPTER: ADMINISTRATION OF COSELA
Jennifer Webster (06:09):
COSELA patient education resources are available for you to share with patients, so they better understand how COSELA can help them.
The patient education brochure covers topics like how COSELA works and what to expect from therapy.
Here are some important considerations for the administration process.
The recommended dose is 240 mg/m2.
Administer COSELA solution within 4 hours prior to the start of chemotherapy.
Follow your institution’s standard of care for pre-med administration for extensive-stage small cell lung cancer patients.
COSELA should be administered as a 30-minute infusion.
The in-line filter should be a standard 0.2 or 0.22 microns.
Jennifer Webster (06:58):
For example, polyethylene sulfone, polyvinylidene fluoride or cellulose acetate.
Do not administer prepared COSELA solutions with a polytetrafluorethylene, or PTFE, in-line filter.
Do not co-administer other drugs through the same infusion line. Do not co-administer other drugs through a central access device unless the device supports co-administration of incompatible drugs.
Once administration is complete, flush the infusion line with at least 20 mL of sterile 5% Dextrose Injection or 0.9% Sodium Chloride Injection. Flushing the line is a very important final step as flushing may help reduce local irritation or inflammation.
Because infusion-site reactions can occur during the infusion, be sure to monitor the infusion site throughout administration.
CHAPTER: RECOMMENDATIONS FOR ADVERSE REACTIONS, INCLUDING INJECTION-SITE REACTIONS
Jennifer Webster (08:00):
COSELA is not a vesicant. However, some patients may experience injection-site reactions such as redness, tenderness, pain, itching, warmth, or swelling.
Reactions, including phlebitis, an inflammation of the vein, and thrombophlebitis, an inflammation of the vein in conjunction with formation of a blood clot, occurred in 21% of the 272 patients receiving COSELA in clinical trials. 10% were Grade 2 adverse reactions and 0.4% were Grade 3.
Injection-site reactions, including phlebitis and thrombophlebitis, resolved in 49 of 56 patients, or 88%, and led to discontinuation of treatment in 3 of 272 patients, or 1%.
Here are some ways you can address injection-site reactions that may occur.
Jennifer Webster (08:59):
In the case of a Grade 1 adverse reaction, interrupt or slow the infusion and/or change the diluent. For Grade 2 adverse reactions that are severe, stop the infusion and consider rotating the injection site or using central venous access. If 0.9% Sodium Chloride Injection is being used as a diluent and flush, consider changing to 5% Dextrose Injection, as appropriate for subsequent infusions.
Ice or cold packs or warm compresses, depending on the patient's symptoms, may also be considered.
Based on published literature, follow your institution's best practices on managing injection-site irritation or inflammation.
In the event of Grade 3 or 4 adverse reactions, stop the infusion and permanently discontinue COSELA. Permanently discontinue COSELA in cases of acute drug hypersensitivity reactions, Grade 3 or 4, and if Grade 2 recurs, interstitial lung disease or pneumonitis Grades 3 or 4, and if symptomatic Grade 2 recurs, other toxicities Grade 4, and if Grade 3 recurs.
Jennifer Webster (10:14):
Warnings and Precautions for COSELA also include acute drug hypersensitivity, interstitial lung disease or pneumonitis, and embryo-fetal toxicity.
Signs and symptoms to monitor include: acute drug hypersensitivity reactions, including facial, eye and tongue edema, urticaria, pruritus, and anaphylactic reactions, as well as pulmonary symptoms indicative of interstitial lung disease or pneumonitis, such as cough, dyspnea, and hypoxia.
CHAPTER: MANAGING MODIFICATIONS AND SCHEDULING DELAYS
Jennifer Webster (10:48):
It is very important to follow the recommended dosing so that the effect of COSELA is optimized. The recommended dosing is intended to maintain hematopoietic stem and progenitor cells in transient arrest while chemotherapy is present in the body.
If the COSELA dose is missed, discontinue chemotherapy on the day the COSELA dose was missed. Consider resuming both COSELA and chemotherapy on the next scheduled day for chemotherapy. If COSELA is discontinued, wait 96 hours from the last dose of COSELA before resuming chemotherapy only.
Jennifer Webster (11:30):
