4.1. Therapeutic indications

TALVEY is indicated as monotherapy for the treatment of adult patients with relapsed and refractory multiple myeloma, who have received at least 3 prior therapies, including an immunomodulatory agent, a proteasome inhibitor, and an anti-CD38 antibody and have demonstrated disease progression on the last therapy.

4.2. Posology and method of administration

Treatment with TALVEY should be initiated and supervised by physicians experienced in the treatment of multiple myeloma.

TALVEY should be administered by a healthcare professional with adequately-trained medical personnel and appropriate medical equipment to manage severe reactions, including cytokine release syndrome (CRS) and neurologic toxicity, including immune effector cell-associated neurotoxicity syndrome (ICANS).

Posology

Pre-treatment medicinal products should be administered prior to each dose of TALVEY during the step-up phase (see below).

TALVEY should be administered subcutaneously on a weekly or biweekly (every 2 weeks) dosing schedule according to Table 1. Patients who receive talquetamab according to the 0.4 mg/kg weekly dosing schedule and have attained an adequate clinical response that is confirmed in at least two consecutive disease assessments can be considered for switch to the 0.8 mg/kg biweekly dosing schedule.

a Based on actual body weight and administered subcutaneously.
b Dose may be administered between 2 to 4 days after the previous dose and may be given up to 7 days after the previous dose to allow for resolution of adverse reactions.
c Maintain a minimum of 6 days between weekly doses and a minimum of 12 days between biweekly (every 2 weeks) doses.

Patients should be instructed to remain within proximity of a healthcare facility and monitored for 48 hours after administration of all doses within the TALVEY step-up phase for signs and symptoms of CRS and ICANS (see section 4.4).

Duration of treatment

Patients should be treated with TALVEY until disease progression or unacceptable toxicity.

Pre-treatment

The following pre-treatment medicinal products must be administered 1 to 3 hours before each dose of TALVEY during the step-up phase to reduce the risk of CRS (see section 4.4).

  • Corticosteroid (oral or intravenous dexamethasone 16 mg or equivalent)
  • Antihistamine (oral or intravenous diphenhydramine 50 mg or equivalent)
  • Antipyretics (oral or intravenous paracetamol 650 mg to 1 000 mg or equivalent)

Pre-treatment medicinal products should be administered prior to subsequent doses for patients who repeat doses within the TALVEY step-up phase due to dose delays (see Table 2) or for patients who experienced CRS (see Table 3).

Prevention of infection

Prior to starting treatment with TALVEY, prophylaxis should be considered for the prevention of infections, per local institutional guidelines.

Dose delays

If a dose of TALVEY is delayed, therapy should be restarted based on recommendations in Table 2, and weekly or biweekly dosing should be resumed accordingly (see Posology above). Pre-treatment medicinal products should be administered prior to restarting TALVEY, and patients should be monitored accordingly (see section 4.2).

* Administer pretreatment medicinal products prior to restarting TALVEY. After restarting TALVEY, resume weekly or biweekly (every 2 weeks) dosing accordingly (see section 4.2).

Dose modifications for adverse reactions

Dose delays may be required to manage toxicities related to TALVEY (see section 4.4). See Table 2 for recommendations on restarting TALVEY after a dose delay.

See Tables 3 and 4 for recommended actions for the management of CRS and ICANS. See Table 6 for recommended dose modifications for other adverse reactions.

Cytokine release syndrome (CRS)

CRS should be identified based on clinical presentation (see section 4.4). Other causes of fever, hypoxia, and hypotension should be evaluated and treated. If CRS is suspected, TALVEY should be withheld until CRS resolves and should be managed according to the recommendations in Table 3. Supportive therapy for CRS should be administered, which may include intensive care for severe or life-threatening CRS. Laboratory testing should be considered to monitor for disseminated intravascular coagulation (DIC), haematology parameters, as well as pulmonary, cardiac, renal, and hepatic function.

Special populations

Paediatric population

There is no relevant use of TALVEY in the paediatric population in the treatment of multiple myeloma.

Elderly (65 years of age and older)

No dose adjustment is required (see section 5.2).

Renal impairment

No dose adjustment is recommended for patients with mild or moderate renal impairment (see section 5.2).

  • Check that the TALVEY solution for injection is colourless to light yellow. Do not use if the solution is discoloured, cloudy, or if foreign particles are present.
  • Remove the appropriate strength TALVEY vial from refrigerated storage (2°C to 8°C) and equilibrate to ambient temperature (15°C to 30°C) for at least 15 minutes. Do not warm TALVEY vial in any other way.
  • Once equilibrated, gently swirl the vial for approximately 10 seconds to mix. Do not shake.
  • Withdraw the required injection volume of TALVEY from the vial(s) into an appropriately sized syringe using a transfer needle.
    • Each injection volume should not exceed 2.0 mL. Divide doses requiring greater than 2.0 mL equally into multiple syringes.
  • TALVEY is compatible with stainless steel injection needles and polypropylene or polycarbonate syringe material.
  • Replace the transfer needle with an appropriately sized needle for injection.
  • If the prepared syringe is stored in the refrigerator, allow the solution to come to ambient temperature before administration.
  • Any unused medicinal product or waste material should be disposed in accordance with local requirements.
