Talvey is a brand-name drug that’s prescribed for multiple myeloma when other treatments haven’t worked. Talvey contains the active drug talquetamab-tgvs. It comes as a subcutaneous injection.
Talvey is prescribed to treat multiple myeloma (a type of cancer that affects certain blood cells) in adults. It’s prescribed for people who have already received four or more different drug regimens to treat this condition, including specific types of drugs, but the cancer either didn’t respond or came back.
You’ll find key information about Talvey below.
Talvey is available only as a brand-name medication. It contains the active drug talquetamab-tgvs.* This active drug isn’t currently available in generic form.
A generic drug is an exact copy of the active drug in a brand-name medication. Generics typically cost less than brand-name drugs.
*The reason “-tgvs” appears at the end of the drug’s name is to show that the drug is distinct from similar medications that may be created in the future.
The Talvey dosage your doctor prescribes will depend on several factors. These include:
- your body weight
- how your body responds to the drug
The following information describes dosages that are commonly prescribed or recommended. However, be sure to follow the dosage your doctor prescribes for you. Your doctor will determine the best dosage to fit your needs.
Drug forms and strengths
Talvey comes as a solution in a vial. The drug is available in two strengths: 2 milligrams per milliliter (mg/mL) and 40 mg/mL.
Talvey is given as a subcutaneous injection. It’s typically injected under the skin of your abdomen. Your doctor may need to administer multiple injections to give you your full dose.
The drug can only be given by a healthcare professional who has received special training to manage certain serious side effects* that are possible during Talvey treatment. You may need to stay in the hospital for at least 48 hours after receiving a dose of Talvey.
Dosage for multiple myeloma
For the first few doses of Talvey, your doctor will determine your dosage by following a “step-up” dosing schedule. Step-up dosing is a schedule by which the doctor slowly increases the dosage over time to reach the target dose. This reduces the risk of serious side effects, including cytokine release syndrome.
Your doctor will calculate your exact dose based on your body weight in kilograms (kg). For reference, 1 kg is about 2.2 pounds (lb).
After you complete the initial step-up schedule, Talvey may be given once every 1 or 2 weeks.
Below is an example of a weekly dosing schedule for Talvey for an adult who weighs 70 kg (about 154 lb):
|Day or week
|Dose example for 70-kg adult
|step-up dose: 0.01 milligrams per kilogram (mg/kg)
|step-up dose: 0.06 mg/kg
|first treatment dose: 0.4 mg/kg
|subsequent treatment doses: 0.4 mg/kg once weekly
Below is an example of a biweekly (every 2 weeks) dosing schedule for Talvey for an adult who weighs 70 kg (about 154 lb):
|Day or week
|Dose example for 70-kg adult
|step-up dose: 0.01 mg/kg
|step-up dose: 0.06 mg/kg
|step-up dose: 0.4 mg/kg
|first treatment dose: 0.8 mg/kg
|once every 2 weeks
|subsequent treatment doses: 0.8 mg/kg once every 2 weeks
Your doctor may give you a different dosage or delay your next dose depending on several factors. These may include whether you develop certain side effects from Talvey, the specific symptoms and severity of these side effects, and how long it takes your body to recover from them.
To help prevent or reduce certain side effects from Talvey, your doctor will give you pretreatment medications. These are typically given 1–3 hours before Talvey and include:
- a corticosteroid such as dexamethasone (Hemady)
- an antihistamine such as diphenhydramine (Benadryl)
- a fever reducer such as acetaminophen (Tylenol)

Here are answers to some frequently asked questions about Talvey.
How does Talvey work?
Talvey is a bispecific antibody drug. “Bispecific” means that the drug can bind to two different targets at the same time. Talvey treats multiple myeloma by attaching to the following types of receptors (proteins) in the body:
- G protein-coupled receptor class C group 5 member D (GPRC5D), which is a receptor on the surface of multiple myeloma cells as well as various types of healthy cells
- CD3, which is a receptor on the surface of T cells (T cells are part of the immune system and help fight cancer)
By attaching to GPRC5D and CD3 at the same time, Talvey acts as a bridge connecting multiple myeloma cells and T cells. When the drug attaches to the T cell, it activates the T cell to attack the connected cancer cell.
If you have additional questions about Talvey’s mechanism of action (how the drug works), talk with your doctor or pharmacist.
Will Talvey cure multiple myeloma?
Talvey hasn’t been shown to cure multiple myeloma. However, in a clinical trial, some people experienced a complete response. This means that the number of multiple myeloma cells became too low to be detected by medical tests.
Keep in mind that individual results can differ from what was seen in the clinical trial.
Talvey works by helping your immune system attack cancer cells. It’s a type of immunotherapy. Talk with your doctor for more information about what to expect with Talvey treatment.
Can Talvey cause long-term side effects?
It isn’t known whether Talvey causes long-term side effects. It’s a new drug, and clinical trials are still researching its safety and effectiveness.
If you develop bothersome or severe side effects during Talvey treatment, tell your doctor. They’ll help you determine whether the treatment should be paused or stopped. They’ll also recommend ways to manage the drug’s side effects.
Talk with your doctor if you have questions about how long side effects may last with this medication.
This drug comes with several precautions.
This drug has boxed warnings. A boxed warning is the most serious warning from the Food and Drug Administration (FDA). It alerts doctors and patients about drug effects that may be dangerous.
Symptoms of CRS may include:
- fever or chills
- feeling dizzy or anxious
- shortness of breath
- fast heart rate
To lower this risk, doctors typically prescribe a low starting dose of Talvey and slowly increase it over time. They’ll likely also give you medications before each dose of Talvey to help prevent CRS. To monitor for CRS and other side effects, you may need to stay in the hospital for 48 hours after you receive Talvey.
If CRS occurs, your doctor will likely have you stop treatment with Talvey. After you recover from CRS, your doctor will determine whether it’s safe for you to consider restarting the drug.
Risk of serious neurologic damage. Talvey may cause problems with the nervous system. This can lead to a condition called immune effector cell-associated neurotoxicity syndrome (ICANS), which can be serious or even life threatening. Neurologic damage, including ICANS, was a common side effect in Talvey’s clinical trial.
Symptoms of serious neurologic damage may include:
To lower this risk, doctors typically prescribe a low starting dose of Talvey and slowly increase it over time. To monitor for ICANS and other side effects, you may need to stay in the hospital for 48 hours after you receive Talvey.
If signs or symptoms of neurologic damage develop during Talvey treatment, your doctor will likely have you stop treatment with it. After you recover, your doctor will determine whether it’s safe for you to consider restarting the drug.
Before receiving Talvey, discuss your health history with your doctor. Talvey may not be right for you if you have certain medical conditions or other factors affecting your health. Be sure to talk with your doctor if any of the following apply to you:
