Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Check that the TALVEY solution for injection is colorless to light yellow. Do not use if the solution is discolored, cloudy, or if foreign particles are present.
Remove the appropriate strength TALVEY vial(s) from refrigerated storage [2°C to 8°C (36°F to 46°F)] and equilibrate to ambient temperature [15°C to 30°C (59°F to 86°F)] for at least 15 minutes. Do not warm TALVEY 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 mL. Divide doses requiring greater than 2 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.

Administration

Inject the required volume of TALVEY into the subcutaneous tissue of the abdomen (preferred injection site). Alternatively, TALVEY may be injected into the subcutaneous tissue at other sites (e.g., thigh). If multiple injections are required, TALVEY injections should be at least 2 cm apart.
Do not inject into tattoos or scars or areas where the skin is red, bruised, tender, hard or not intact.
Any unused medicinal product or waste material should be disposed in accordance with local requirements.

Storage

The prepared syringes should be administered immediately. If immediate administration is not possible, store the TALVEY solution refrigerated at 2°C to 8°C (36°F to 46°F) for up to 24 hours followed by at room temperature of 15°C to 30°C (59°F to 86°F) for up to 24 hours. Discard if stored for more than 24 hours refrigerated or more than 24 hours at room temperature. If stored in the refrigerator, allow the solution to come to room temperature before administration.

5. Warnings and Precautions

5.1 Cytokine Release Syndrome (CRS)

TALVEY can cause cytokine release syndrome, including life-threatening or fatal reactions [see Adverse Reactions (6.1)] .

In the clinical trial, CRS occurred in 76% of patients who received TALVEY at the recommended dosages, with Grade 1 CRS occurring in 57% of patients, Grade 2 in 17%, and Grade 3 in 1.5%. Recurrent CRS occurred in 30% of patients. Most events occurred following step-up dose 1 (29%) or step-up dose 2 (44%) at the recommended dosages. CRS occurred in 33% of patients with step-up dose 3 in the biweekly dosing schedule (N=153). CRS occurred in 30% of patients with the first 0.4 mg/kg treatment dose and in 12% of patients treated with the first 0.8 mg/kg treatment dose. The CRS rate for both dosing schedules combined was less than 3% for each of the remaining doses in Cycle 1 and less than 3% cumulatively from Cycle 2 onward. The median time to onset of CRS was 27 (range: 0.1 to 167) hours from the last dose, and the median duration was 17 (range: 0 to 622) hours. Clinical signs and symptoms of CRS include but are not limited to pyrexia, hypotension, chills, hypoxia, headache, and tachycardia. Potentially life-threatening complications of CRS may include cardiac dysfunction, acute respiratory distress syndrome, neurologic toxicity, renal and/or hepatic failure, and disseminated intravascular coagulation (DIC).

Initiate TALVEY therapy with step-up dosing and administer pre-treatment medications (corticosteroids, antihistamine, and antipyretics) prior to each dose of TALVEY in the step-up dosing schedule to reduce the risk of CRS. Monitor patients following administration accordingly. In patients who experience CRS, pre-treatment medications should be administered prior to the next TALVEY dose [see Dosage and Administration (2.2, 2.3)].

Counsel patients to seek medical attention should signs or symptoms of CRS occur. At the first sign of CRS, immediately evaluate patient for hospitalization and institute treatment with supportive care based on severity and consider further management per current practice guidelines. Withhold TALVEY until CRS resolves or permanently discontinue based on severity [see Dosage and Administration (2.5)] .

TALVEY is available only through a restricted program under a REMS [see Warnings and Precautions (5.3)] .

5.2 Neurologic Toxicity including ICANS

TALVEY can cause serious, life-threatening, or fatal neurologic toxicity, including ICANS [see Adverse Reactions (6.1)] .

In the clinical trial, neurologic toxicity, including ICANS, occurred in 55% of patients who received TALVEY at the recommended dosages, with Grade 3 or 4 neurologic toxicity occurring in 6% of patients. The most frequent neurologic toxicities were headache (20%), encephalopathy (15%), sensory neuropathy (14%), and motor dysfunction (10%).

ICANS was reported in 9% of 265 patients where ICANS was collected and who received TALVEY at the recommended dosages [see Adverse Reactions (6.1)] . Recurrent ICANS occurred in 3% of patients. Most patients experienced ICANS following step-up dose 1 (3%), step-up dose 2 (3%), step-up dose 3 of the biweekly dosing schedule (1.8%), or the initial treatment dose of the weekly dosing schedule (2.6%) (N=156) or the biweekly dosing schedule (3.7%) (N=109). The median time to onset of ICANS was 2.5 (range: 1 to 16) days after the most recent dose with a median duration of 2 (range: 1 to 22) days. The onset of ICANS can be concurrent with CRS, following resolution of CRS, or in the absence of CRS. Clinical signs and symptoms of ICANS may include but are not limited to confusional state, depressed level of consciousness, disorientation, somnolence, lethargy, and bradyphrenia.

Monitor patients for signs and symptoms of neurologic toxicity during treatment. At the first sign of neurologic toxicity, including ICANS, immediately evaluate the patient and provide supportive care based on severity; withhold or permanently discontinue TALVEY based on severity and consider further management per current practice guidelines [see Dosage and Administration (2.5)].

Due to the potential for neurologic toxicity, patients receiving TALVEY are at risk of depressed level of consciousness. Advise patients to refrain from driving or operating heavy or potentially dangerous machinery during the step-up dosing schedule and for 48 hours after completion of the step-up dosing schedule [see Dosage and Administration (2.2)] and in the event of new onset of any neurological symptoms, until symptoms resolve.

TALVEY is available only through a restricted program under a REMS [see Warnings and Precautions (5.3)] .

5.3 TECVAYLI and TALVEY REMS

TALVEY is available only through a restricted program under a REMS called the TECVAYLI and TALVEY REMS because of the risks of CRS and neurologic toxicity, including ICANS [see Warnings and Precautions (5.1, 5.2)].

Notable requirements of the TECVAYLI and TALVEY REMS include the following:

Prescribers must be certified with the program by enrolling and completing training.
Prescribers must counsel patients receiving TALVEY about the risk of CRS and neurologic toxicity, including ICANS and provide patients with Patient Wallet Card.
Pharmacies and healthcare settings that dispense TALVEY must be certified with the TECVAYLI and TALVEY REMS program and must verify prescribers are certified through the TECVAYLI and TALVEY REMS program.
Wholesalers and distributers must only distribute TALVEY to certified pharmacies.

Further information about the TECVAYLI and TALVEY REMS program is available at www.TEC-TALREMS.com or by telephone at 1-855-810-8064.

5.4 Oral Toxicity and Weight Loss

TALVEY can cause oral toxicities, including dysgeusia, dry mouth, dysphagia, and stomatitis [see Adverse Reactions (6.1)] .

In the clinical trial, 80% of patients had oral toxicity, with Grade 3 occurring in 2.1% of patients who received TALVEY at the recommended dosages. The most frequent oral toxicities were dysgeusia (49%), dry mouth (34%), dysphagia (23%), and ageusia (18%). The median time to onset of oral toxicity was 15 (range: 1 to 634) days, and the median time to resolution to baseline was 43 (1 to 530) days. Oral toxicity did not resolve to baseline in 65% of patients.

TALVEY can cause weight loss [see Adverse Reactions (6.1)] . In the clinical trial, 62% of patients experienced weight loss, regardless of having an oral toxicity, including 29% of patients with Grade 2 (10% or greater) weight loss and 2.7% of patients with Grade 3 (20% or greater) weight loss. The median time to onset of Grade 2 or higher weight loss was 67 (range: 6 to 407) days, and the median time to resolution was 50 (range: 1 to 403) days. Weight loss did not resolve in 57% of patients who reported weight loss.

Monitor patients for signs and symptoms of oral toxicity. Counsel patients to seek medical attention should signs or symptoms of oral toxicity occur and provide supportive care as per current clinical practice including consultation with a nutritionist. Monitor weight regularly during therapy. Evaluate clinically significant weight loss further. Withhold TALVEY or permanently discontinue based on severity [see Dosage and Administration (2.5)] .

5.5 Infections

TALVEY can cause serious infections, including life-threatening or fatal infections [see Adverse Reactions (6.1)] .

In the clinical trial, serious infections occurred in 16% of patients, with fatal infections in 1.5% of patients. Grade 3 or 4 infections occurred in 17% of patients. The most common serious infections reported were bacterial infection (8%), which included sepsis, and COVID-19 (2.7%).

Monitor patients for signs and symptoms of infection prior to and during treatment with TALVEY and treat appropriately. Administer prophylactic antimicrobials according to local guidelines. Withhold or consider permanent discontinuation of TALVEY as recommended based on severity [see Dosage and Administration (2.5)] .

5.6 Cytopenias

TALVEY can cause cytopenias, including neutropenia and thrombocytopenia [see Adverse Reactions (6.1)] .

In the clinical trial, Grade 3 or 4 decreased neutrophils occurred in 35% of patients, and Grade 3 or 4 decreased platelets occurred in 22% of patients who received TALVEY. The median time to onset for Grade 3 or 4 neutropenia was 22 (range: 1 to 312) days, and the median time to resolution to Grade 2 or lower was 8 (range: 1 to 79) days. The median time to onset for Grade 3 or 4 thrombocytopenia was 12 (range: 2 to 183) days, and the median time to resolution to Grade 2 or lower was 10 (range: 1 to 64) days. Monitor complete blood counts during treatment and withhold TALVEY as recommended based on severity [see Dosage and Administration (2.5)] .

5.7 Skin Toxicity

TALVEY can cause serious skin reactions, including rash, maculo-papular rash, erythema, and erythematous rash [see Adverse Reactions (6.1)] .

In the clinical trial, skin reactions occurred in 62% of patients, with Grade 3 skin reactions in 0.3%. The median time to onset was 25 (range: 1 to 630) days. The median time to improvement to Grade 1 or less was 33 days.

Monitor for skin toxicity, including rash progression. Consider early intervention and treatment to manage skin toxicity. Withhold TALVEY as recommended based on severity [see Dosage and Administration (2.5)] .

5.8 Hepatotoxicity

TALVEY can cause hepatotoxicity. In the clinical trial, elevated ALT occurred in 33% of patients, with Grade 3 or 4 ALT elevation occurring in 2.7%; elevated AST occurred in 31% of patients, with Grade 3 or 4 AST elevation occurring in 3.3%. Grade 3 or 4 elevations of total bilirubin occurred in 0.3% of patients [see Adverse Reactions (6.1)] . Liver enzyme elevation can occur with or without concurrent CRS.

Monitor liver enzymes and bilirubin at baseline and during treatment as clinically indicated. Withhold TALVEY or consider permanent discontinuation of TALVEY based on severity [see Dosage and Administration (2.5)] .

5.9 Embryo-Fetal Toxicity

Based on its mechanism of action, TALVEY may cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to the fetus. Advise females of reproductive potential to use effective contraception during treatment with TALVEY and for 3 months after the last dose [see Use in Specific Populations (8.1, 8.3)] .

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Relapsed/Refractory Multiple Myeloma

MonumenTAL-1

The safety of TALVEY was evaluated in 339 adult patients with relapsed or refractory multiple myeloma. Patients treated with the weekly dosing schedule received step-up doses of 0.01 mg/kg and 0.06 mg/kg of TALVEY followed by TALVEY 0.4 mg/kg subcutaneously weekly thereafter. Patients treated with the biweekly (every 2 weeks) dosing schedule received step-up doses of 0.01 mg/kg, 0.06 mg/kg, and 0.3 mg/kg (0.75 times the recommended step-up dose 3) followed by TALVEY 0.8 mg/kg subcutaneously every 2 weeks thereafter. The duration of exposure for the 0.4 mg/kg weekly regimen was 5.9 (range: 0.0 to 25.3) months (N=186) and for the 0.8 mg/kg biweekly (every 2 weeks) regimen, it was 3.7 (range: 0.0 to 17.9) months (N=153).

Serious adverse reactions occurred in 47% of patients who received TALVEY. Serious adverse reactions in ≥ 2% of patients included CRS (13%), bacterial infection (8%) including sepsis, pyrexia (4.7%), ICANS (3.8%), COVID-19 (2.7%), neutropenia (2.1%), and upper respiratory tract infection (2.1%).

Fatal adverse reactions occurred in 3.2% of patients who received TALVEY, including COVID -19 (0.6%), dyspnea (0.6%), general physical health deterioration (0.6%), bacterial infection (0.3%) including sepsis, basilar artery occlusion (0.3%), fungal infection (0.3%), infection (0.3%), and pulmonary embolism (0.3%).

Permanent discontinuation of TALVEY due to an adverse reaction occurred in 9% of patients. Adverse reactions which resulted in permanent discontinuation of TALVEY in > 1% of patients included ICANS.

Dosage interruptions of TALVEY due to an adverse reaction occurred in 56% of patients. Adverse reactions which required dosage interruption in > 5% of patients included pyrexia (15%), CRS (12%), upper respiratory tract infection (9%), COVID-19 (9%), bacterial infection (7%) including sepsis, neutropenia (6%), and rash (6%).

The most common adverse reactions (≥ 20%) were pyrexia, CRS, dysgeusia, nail disorder, musculoskeletal pain, skin disorder, rash, fatigue, weight decreased, dry mouth, xerosis, dysphagia, upper respiratory tract infection, diarrhea, hypotension, and headache. The most common Grade 3 or 4 laboratory abnormalities (≥ 30%) were lymphocyte count decreased, neutrophil count decreased, white blood cell decreased, and hemoglobin decreased.

7. Drug Interactions

For certain cytochrome P450 (CYP) substrates, minimal changes in the substrate concentration may lead to serious adverse reactions. Monitor for toxicity or drug concentrations of such CYP substrates when co-administered with TALVEY.

Talquetamab-tgvs causes release of cytokines [see Clinical Pharmacology (12.2)] that may suppress activity of CYP enzymes, resulting in increased exposure of CYP substrates. Increased exposure of CYP substrates is more likely to occur from initiation of the TALVEY step-up dosing schedule up to 14 days after the first treatment dose and during and after CRS [see Warnings and Precautions (5.1)] .

8. Use In Specific Populations

8.1 Pregnancy

Risk Summary

Based on the mechanism of action, TALVEY may cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1)] . There are no available data on the use of TALVEY in pregnant women to evaluate for a drug associated risk. No animal reproductive or developmental toxicity studies have been conducted with talquetamab-tgvs.

Talquetamab-tgvs causes T-cell activation and cytokine release; immune activation may compromise pregnancy maintenance. Human immunoglobulin G (IgG) is known to cross the placenta; therefore, TALVEY has the potential to be transmitted from the mother to the developing fetus. Advise women of the potential risk to the fetus.

In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

8.2 Lactation

Risk Summary

There is no information regarding the presence of talquetamab-tgvs in human milk, the effect on the breastfed child, or the effect on milk production. Maternal IgG is known to be present in human milk. The effects of local gastrointestinal exposure and limited systemic exposure in the breastfed child to TALVEY are unknown. Because of the potential for serious adverse reactions in a breastfed child, advise women not to breastfeed during treatment with TALVEY and for 3 months after the last dose.

8.3 Females and Males of Reproductive Potential

TALVEY may cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)] .

Pregnancy Testing

Verify pregnancy status of females of reproductive potential prior to initiating TALVEY.

Contraception

Females

Advise females of reproductive potential to use effective contraception during treatment with TALVEY and for 3 months after the last dose.

8.4 Pediatric Use

The safety and efficacy of TALVEY have not been established in pediatric patients.

8.5 Geriatric Use

There were 339 patients in the clinical trial for relapsed or refractory multiple myeloma. Of the total number of TALVEY-treated patients in the study, 178 (53%) patients were 65 years of age and older, while 57 (17%) patients were 75 years of age and older. No overall differences in safety or effectiveness were observed in patients 65 to less than 74 years of age compared to younger patients. There was a higher rate of fatal adverse reactions in patients 75 years of age or older compared to younger patients [see Adverse Reactions (6.1)]. Clinical studies did not include sufficient numbers of patients 75 years of age or over to determine whether they respond differently from younger patients.

11. Talvey Injection Description

Talquetamab-tgvs is a bispecific GPRC5D-directed CD3 T-cell engager. It is a humanized IgG4 proline, alanine, alanine (IgG4-PAA)-based bispecific antibody produced by Chinese hamster ovary (CHO) cells using recombinant DNA technology. Talquetamab-tgvs consists of an anti-GPRC5D heavy chain and light chain and an anti-CD3 heavy chain and light chain with two interchain disulfide bonds connecting the two arms. The molecular weight of talquetamab-tgvs is 147 kDa.

TALVEY™ (talquetamab-tgvs) injection is a sterile, preservative-free colorless to light yellow solution supplied in a single-dose vial for subcutaneous administration.

Each TALVEY 1.5 mL single-dose vial contains 3 mg of talquetamab-tgvs, edetate disodium (0.027 mg), glacial acetic acid (0.36 mg), polysorbate 20 (0.6 mg), sodium acetate (1.39 mg), sucrose (120 mg), and Water for Injection, USP. The pH is 5.2.

Each TALVEY 1 mL single-dose vial contains 40 mg of talquetamab-tgvs, edetate disodium (0.018 mg), glacial acetic acid (0.24 mg), polysorbate 20 (0.4 mg), sodium acetate (0.90 mg), sucrose (80 mg), and Water for Injection, USP. The pH is 5.2.

12. Talvey Injection - Clinical Pharmacology

12.1 Mechanism of Action

Talquetamab-tgvs is a bispecific T-cell engaging antibody that binds to the CD3 receptor expressed on the surface of T-cells and G protein-coupled receptor class C group 5 member D (GPRC5D) expressed on the surface of multiple myeloma cells and non-malignant plasma cells, as well as healthy tissues such as epithelial cells in keratinized tissues of the skin and tongue.

In vitro, talquetamab-tgvs activated T-cells caused the release of proinflammatory cytokines and resulted in the lysis of multiple myeloma cells. Talquetamab-tgvs had anti-tumor activity in mouse models of multiple myeloma.

12.2 Pharmacodynamics

Serum concentrations of cytokines (IL-6, IL-10, TNF-α, and IFN-γ) and IL-2R were measured before and after administration of each step-up dose, the first three treatment doses at 0.4 mg/kg once weekly, and the first two treatment doses at 0.8 mg/kg every two weeks. Increased concentrations of IL-6, IL-10, and IL-2R were observed during this period.

Higher talquetamab-tgvs exposures (i.e., AUC and C max) are associated with higher incidence of some adverse reactions (including oral toxicity, nail toxicity, and skin reactions). The exposure-response relationships for effectiveness and the time course of pharmacodynamic response of talquetamab-tgvs have not been fully characterized.

12.3 Pharmacokinetics

The C maxand AUC tauof talquetamab-tgvs after subcutaneous administration increased proportionally over a dose range of 0.005 to 0.8 mg/kg weekly (0.01 to 2 times the recommended 0.4 mg/kg weekly treatment dose) and 0.8 to 1.2 mg/kg every two weeks (1 to 1.5 times the recommended 0.8 mg/kg every 2 weeks treatment dose). Ninety percent of steady state exposure was achieved 16 weeks after the first treatment dose for both regimens.

The C max, C trough, C avg, and accumulation ratios of talquetamab-tgvs are presented in Table 15.

Absorption

The geometric mean (coefficient of variation [CV] %) bioavailability of talquetamab-tgvs was 59% (22%) when administered subcutaneously.

The median (range) T maxof talquetamab-tgvs after the first and 17 thtreatment dose of 0.4 mg/kg weekly were 3.7 (0.9 to 7) days and 2.5 (0.9 to 5.9) days, respectively.

The median (range) T maxof talquetamab-tgvs after the first and 9 thtreatment dose of 0.8 mg/kg every 2 weeks were 3.4 (0.8 to 14) days and 3.6 (1 to 7.7) days, respectively.

Distribution

The geometric mean (CV%) volume of distribution of talquetamab-tgvs was 10.1 L (25%).

Elimination

Talquetamab-tgvs clearance decreases over time, with a mean (CV%) maximal reduction from the first treatment dose to 16 weeks after the first treatment dose of 40% (56%). The geometric mean (CV%) clearance is 0.90 L/day (63%) at 16 weeks after the first treatment dose. The mean (CV%) terminal half-life was 8.4 (41%) days after the first treatment dose and 12.2 (49%) days at 16 weeks after the first treatment dose.

Metabolism

Talquetamab-tgvs is expected to be metabolized into small peptides by catabolic pathways.

Specific Populations

The volume of distribution and clearance of talquetamab-tgvs increased with increasing bodyweight (40 kg to 143 kg).

There were no clinically significant differences in the pharmacokinetics of talquetamab-tgvs based on age (33 to 86 years), sex, race (White, Black or African American), ethnicity (Not Hispanic/Latino, Hispanic/Latino), mild or moderate renal impairment (creatinine clearance [CLcr] by Cockcroft-Gault equation: 30 to 89 mL/min) or mild (total bilirubin less than or equal to upper limit of normal [ULN] with AST greater than ULN or total bilirubin greater than 1 to 1.5 times ULN with any AST) or moderate (total bilirubin greater than 1.5 to less than 3 times ULN with any AST) hepatic impairment. The effects of severe renal impairment (CLcr less than 30 mL/min) or severe hepatic impairment (total bilirubin greater than 3 times ULN with any AST) on the pharmacokinetics of talquetamab-tgvs are unknown.

12.6 Immunogenicity

The observed incidence of anti-drug antibodies is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of anti-drug antibodies in the studies described below with the incidence of anti-drug antibodies in other studies, including those of talquetamab-tgvs or of other talquetamab products.

During treatment in MonumenTAL-1 (up to 25 months), 45/177 (25%) patients treated with subcutaneous TALVEY 0.4 mg/kg weekly (median follow-up 5.7 months) and 24/130 (18%) patients treated with subcutaneous TALVEY 0.8 mg/kg every 2 weeks (median follow-up 3.1 months) developed anti-talquetamab-tgvs antibodies. There was no identified clinically significant effect of anti-talquetamab-tgvs antibodies on the pharmacokinetics, pharmacodynamics, safety, or effectiveness of TALVEY.

13. Nonclinical Toxicology

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

No carcinogenicity or genotoxicity studies have been conducted with talquetamab-tgvs.

No studies have been conducted to evaluate the effects of talquetamab-tgvs on fertility.

14. Clinical Studies

The efficacy of TALVEY monotherapy was evaluated in patients with relapsed or refractory multiple myeloma in a single-arm, open-label, multicenter study, MMY1001 (MonumenTAL-1) (NCT03399799, NCT04634552). The study included patients who had previously received at least three prior systemic therapies, including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 monoclonal antibody. The study excluded patients who experienced T-cell redirection therapy within 3 months, prior Grade 3 or higher CRS related to any T-cell redirection therapy, an autologous stem cell transplant within the past 12 weeks, an allogeneic stem cell transplant within the past 6 months, Eastern Cooperative Oncology Group (ECOG) performance score of 3 or higher, stroke or seizure within the past 6 months, CNS involvement or clinical signs of meningeal involvement of multiple myeloma, and plasma cell leukemia, active or documented history of autoimmune disease (exception of vitiligo, resolved childhood atopic dermatitis, resolved Grave's Disease that is euthyroid based on clinical and laboratory testing).

Patients treated with the weekly dosing schedule received step-up doses of 0.01 mg/kg and 0.06 mg/kg of TALVEY followed by TALVEY 0.4 mg/kg subcutaneously weekly thereafter.

Patients treated with the biweekly (every 2 weeks) dosing schedule received step-up doses of 0.01 mg/kg, 0.06 mg/kg, and 0.3 mg/kg (0.75 times the recommended step-up dose 3) of TALVEY followed by TALVEY 0.8 mg/kg subcutaneously biweekly, thereafter. Patients on both dosing schedules were treated until disease progression or unacceptable toxicity.

The efficacy results from the 187 patients treated with TALVEY who were not exposed to prior T cell redirection therapy and who had received at least 4 prior lines of therapy are presented below; of these patients, the median age was 67 (range: 38 to 86) years, 57% were male, 90% were White, 5% were Black or African American, 3% were Asian, and 8% were Hispanic. Patients had received a median of 5 (range: 4 to 13) prior lines of therapy, and 78% had received prior autologous stem cell transplantation (ASCT). Ninety-four percent (94%) of patients were refractory to their last therapy, and 73% were refractory to a proteasome inhibitor, immunomodulatory agent, and anti-CD38 antibody. The International Staging System (ISS) at study entry was Stage I in 44%, Stage II in 34%, and Stage III in 22% of patients. High-risk cytogenetic factors (presence of t(4:14), t(14:16), and/or del(17p)) were present in 29% of patients; baseline cytogenetic data were not available in 11% of patients. Twenty-two percent (22%) of patients had extramedullary plasmacytomas.

Efficacy was based on overall response rate (ORR) and duration of response (DOR) as assessed by an Independent Review Committee using IMWG criteria. The median duration of follow-up from first response among responders receiving TALVEY 0.4 mg/kg weekly was 13.8 (range: 0.8 to 15.4) months.

The median time to first response was 1.2 (range: 0.2 to 10.9) months and 1.3 (range: 0.2 to 9.2) months for 0.4 mg/kg weekly and 0.8 mg/kg biweekly (every 2 weeks), respectively.

Thirty-two patients were exposed to prior T cell redirection therapy and had received at least 4 prior lines of therapy, including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 monoclonal antibody received TALVEY at the 0.4 mg/kg weekly dose. Patients had received a median of 6 (range: 4 to 15) prior therapies, with 81% exposed to CAR-T cell therapy and 25% exposed to a bispecific antibody. Ninety-four percent of patients were exposed to prior T cell redirection therapy directed at BCMA. The ORR per IRC assessment was 72% (95% CI: 53%, 86%). With a median duration of follow-up of 10.4 months, an estimated 59% of responders maintained response for at least 9 months.

MEDICATION GUIDE TALVEY™ [tal vay] (talquetamab-tgvs) injection, for subcutaneous use
This Medication Guide has been approved by the U.S. Food and Drug Administration.			Issued: August 2023
What is the most important information I should know about TALVEY? TALVEY may cause side effects that are serious, life-threatening, or lead to death, including Cytokine Release Syndrome (CRS) and neurologic problems. Call your healthcare provider or get medical help right away if you develop any of the signs or symptoms of CRS or neurologic problems listed below at any time during your treatment with TALVEY: Cytokine Release Syndrome (CRS).CRS is common during treatment with TALVEY and can also be serious or life-threatening. Signs and symptoms of CRS may include:
fever (100.4°F or higher) dizziness or lightheadedness chills difficulty breathing		feeling anxious headache fast heartbeat
Neurologic problems.Symptoms of neurologic problems with TALVEY may include:
headache feeling confused being less alert or aware feeling disoriented trouble speaking or writing shaking (tremors) numbness and tingling (feeling like "pins and needles")		feeling sleepy feeling very sleepy with low energy slow or difficulty thinking seizures muscle weakness memory loss burning, throbbing, or stabbing pain
Due to the risk of CRS and neurologic problems, you should be hospitalized for 48 hours after all doses of TALVEY that are part of the "step-up dosing schedule". The "step-up dosing schedule" is when you receive the first 2 or 3 doses of TALVEY, which are smaller "step-up" doses, and also the first full "treatment dose" of TALVEY. TALVEY is given weekly or every 2 weeks. Your healthcare provider will decide the number of days to wait between your doses of TALVEY as well as how many treatments you will receive. If you receive TALVEY weekly, "Step-up dose 1" is given on day 1 of treatment. "Step-up dose 2" is usually given on day 4 of treatment. The first "treatment dose" is usually given on day 7 of treatment. If you receive TALVEY every 2 weeks, "Step-up dose 1" is given on day 1 of treatment. "Step-up dose 2" is usually given on day 4 of treatment. "Step-up dose 3" is usually given on day 7 of treatment. The first "treatment dose" is usually given on day 10 of treatment. If your dose of TALVEY is delayed for any reason, you may need to repeat the "step-up dosing schedule" to receive TALVEY. Before each "step up" dose of TALVEY, you will receive medicines to help reduce your risk of CRS. Your healthcare provider will decide if you need to receive medicines to help reduce your risk of CRS with future doses. Your healthcare provider will monitor you for signs and symptoms of CRS, neurologic problems, as well as other side effects and treat you as needed. TALVEY is available only through the TECVAYLI and TALVEY Risk Evaluation and Mitigation Strategy (REMS) due to the risk of CRS and neurologic problems.
