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.
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).
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.
Table 1. Recommended TALVEY dose:
Dosing schedule | Phase | Day | TALVEY dosea |
---|---|---|---|
Weekly dosing schedule | Step-up phase | Day 1 | 0.01 mg/kg |
Day 3b | 0.06 mg/kg | ||
Day 5b | 0.4 mg/kg | ||
Treatment phase | Once a week thereafterc | 0.4 mg/kg | |
Biweekly (every 2 weeks) dosing schedule | Step-up phase | Day 1 | 0.01 mg/kg |
Day 3b | 0.06 mg/kg | ||
Day 5b | 0.4 mg/kg | ||
Day 7b | 0.8 mg/kg | ||
Treatment phase | Once every 2 weeks thereafterc | 0.8 mg/kg |
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).
Patients should be treated with TALVEY until disease progression or unacceptable toxicity.
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).
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).
Prior to starting treatment with TALVEY, prophylaxis should be considered for the prevention of infections, per local institutional guidelines.
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).
Table 2. Recommendations for restarting TALVEY after dose delay:
Dosing schedule | Last dose administered | Time from last dose administered | TALVEY recommendation* |
---|---|---|---|
Weekly dosing schedule | 0.01 mg/kg | More than 7 days | Restart at 0.01 mg/kg |
0.06 mg/kg | 8 to 28 days | Repeat 0.06 mg/kg | |
More than 28 days | Restart at 0.01 mg/kg | ||
0.4 mg/kg | 8 to 35 days | Repeat 0.4 mg/kg | |
36 to 56 days | Restart at 0.06 mg/kg | ||
More than 56 days | Restart at 0.01 mg/kg | ||
Biweekly (every 2 weeks) dosing schedule | 0.01 mg/kg | More than 7 days | Restart at 0.01 mg/kg |
0.06 mg/kg | 8 to 28 days | Repeat 0.06 mg/kg | |
More than 28 days | Restart at 0.01 mg/kg | ||
0.4 mg/kg | 8 to 35 days | Repeat 0.4 mg/kg | |
36 to 56 days | Restart at 0.06 mg/kg | ||
More than 56 days | Restart at 0.01 mg/kg | ||
0.8 mg/kg | 14 to 35 days | Repeat 0.8 mg/kg | |
36 to 56 days | Restart at 0.4 mg/kg | ||
More than 56 days | Restart at 0.01 mg/kg |
* 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 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.
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.
Table 3. Recommendations for management of CRS:
CRS Gradea | TALVEY actions | Tocilizumabb | Corticosteroidsc |
---|---|---|---|
Grade 1 Temperature ≥38°Cd | Withhold TALVEY until CRS resolves. Administer pre-treatment medicinal product prior to next dose of TALVEY. | May be considered. | Not applicable |

If no improvement or if condition worsens, consider alternate immunosuppressants.c |
a Based on ASTCT grading for CRS (Lee et al 2019).
b Refer to tocilizumab prescribing information for details.
c Treat unresponsive CRS per institutional guidelines.
d Attributed to CRS. Fever may not always be present concurrently with hypotension or hypoxia as it may be masked by interventions such as antipyretics or anticytokine therapy (e.g., tocilizumab or corticosteroids).
e Low-flow nasal cannula is ≤ 6 L/min, and high-flow nasal cannula is >6 L/min.
At the first sign of neurologic toxicity, including ICANS, TALVEY should be withheld and neurology evaluation should be considered. Other causes of neurologic symptoms should be ruled out.
Supportive therapy should be provided, which may include intensive care, for severe or life-threatening ICANS (see section 4.4). Management recommendations for ICANS are summarised in Table 4.
