Cytokine release syndrome (CRS), which may be life threatening, occurred in patients receiving KIMMTRAK. Manifestations of CRS may include fever, hypotension, hypoxia, chills, nausea, vomiting, rash, elevated transaminases, fatigue, and headache. CRS (≥ Grade 2) occurred in 77% of patients in Study IMCgp100-202 who received KIMMTRAK [see Adverse Reactions (6.1)] . Among patients who received KIMMTRAK, 23% received systemic corticosteroids for at least 1 infusion, 8% received supplemental oxygen during at least 1 infusion, and 0.8% received a vasopressor for at least 1 infusion. CRS led to permanent discontinuation in 1.2% of patients.
In Study IMCgp100-202, 60% of patients experienced ≥ Grade 2 CRS with more than 1 infusion, with the median number of events being 2 (range 1 - 12). The majority (84%) of episodes of CRS started the day of infusion. Among cases that resolved, the median time to resolution of CRS was 2 days.
Ensure that healthcare providers administering KIMMTRAK have immediate access to medications and resuscitative equipment to manage CRS. Ensure patients are euvolemic prior to initiating the infusions. Closely monitor patients for signs or symptoms of CRS following infusions of KIMMTRAK [see Dosage and Administration (2.2)] .
Monitor fluid status, vital signs, and oxygenation level and provide appropriate therapy. Withhold or discontinue KIMMTRAK depending on persistence and severity of CRS [see Dosage and Administration (2.3)] .
Skin reactions, including rash, pruritus, and cutaneous edema occurred in patients treated with KIMMTRAK. In study IMCgp100-202, skin reactions occurred in 91% of patients treated with KIMMTRAK, including Grade 2 (44%) and Grade 3 (21%) events. Skin reactions included rash (83%), pruritus (69%), erythema (25%), and cutaneous edema (27%) [see Adverse Reactions (6.1)] .
The median time to onset of skin reactions was 1 day (range: 1 – 55 days). The median time to improvement to ≤ Grade 1 was approximately 6 days.
Monitor patients for skin reactions. If skin reactions occur, treat with antihistamine and topical or systemic steroids based on persistence and severity of symptoms. Withhold or permanently discontinue KIMMTRAK depending on the severity of skin reactions [see Dosage and Administration (2.3)] .
In Study IMCgp100-202, increases in alanine aminotransferase or aspartate aminotransferase were observed in 65% of patients treated with KIMMTRAK.
In patients experiencing ALT/AST elevations, 73% initially occurred within the first 3 infusions with KIMMTRAK. Most patients experiencing Grade 3 or 4 ALT/AST elevations had improvement to ≤ Grade 1 within 7 days. For events that were observed outside the setting of CRS, the median time to onset was 129 days. Grade 3 or greater elevations in liver enzymes outside the setting of CRS occurred in approximately 8% of patients.
Elevations in liver enzymes led to permanent discontinuation in 0.4% of patients receiving KIMMTRAK.
Monitor alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total blood bilirubin prior to the start of and during treatment with KIMMTRAK. Withhold KIMMTRAK according to severity [see Dosage and Administration (2.3)] .
Based on the mechanism of action, KIMMTRAK 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 KIMMTRAK and for 1 week after the last dose [see Use in Specific Populations (8.1,8.3)] .
The following serious adverse reactions are discussed in greater detail in other sections of the label:
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.
First line metastatic uveal melanoma
The safety of KIMMTRAK was evaluated in study IMCgp100-202, a randomized (2:1), open-label, active-controlled trial in patients who had not received prior systemic therapy for metastatic or advanced uveal melanoma [see Clinical Studies (14)] . Patients received either KIMMTRAK administered at 20 mcg intravenously on Day 1, 30 mcg intravenously on Day 8, 68 mcg intravenously on Day 15, and 68 mcg intravenously once every week thereafter (N=245) or investigator’s choice treatment (N=111). The median duration of exposure was 5.3 months (range: 0.3 to 33 months) in patients treated with KIMMTRAK.
Serious adverse reactions occurred in 28% of patients who received KIMMTRAK. Serious adverse reactions occurring in ≥ 2% of patients were cytokine release syndrome (10%), rashes (4.5%), pyrexia (2.4%), and hypotension (2%). One patient (0.4%) experienced a fatal adverse reaction (pulmonary embolism).
Adverse reactions led to permanent discontinuation in 3.3% of patients who received KIMMTRAK. Adverse reactions that led to permanent discontinuation of KIMMTRAK were anaphylactic reaction, brain edema, cytokine release syndrome, fatigue, hepatotoxicity, hypotension, and nausea (each 0.4%).
Adverse reactions resulting in dosage interruption occurred in 25% of patients who received KIMMTRAK. Adverse reactions which required dosage interruption in ≥ 2% of patients included fatigue (3.7%), lipase increased (2.9%), pyrexia (2.4%), alanine aminotransferase increase (2%), and aspartate aminotransferase increase (2%).
Adverse reactions leading to dose reduction occurred in 5% of patients who received KIMMTRAK. Adverse reactions which required dosage reduction in ≥ 2% of patients were cytokine release syndrome (2.4%), and rashes (2%).
The most common adverse reactions (≥30%) in patients who received KIMMTRAK were cytokine release syndrome, rash, pyrexia, pruritus, fatigue, nausea, chills, abdominal pain, edema, hypotension, dry skin, headache, and vomiting. The most common (≥50%) laboratory abnormalities in patient who received KIMMTRAK were decreased lymphocyte count, increased creatinine, increased glucose, increased AST, increased ALT, decreased hemoglobin, and decreased phosphate.

As with all therapeutic proteins, there is potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies in the studies described below with the incidence of antibodies in other studies or to other products may be misleading.
Treatment-emergent anti-drug antibodies (ADA) against tebentafusp-tebn were detected in 33% and 29% of patients receiving tebentafusp-tebn across all doses in study IMCgp100-102 and study IMCgp100-202, respectively. The median onset time to ADA formation was 6-9 weeks after tebentafusp-tebn treatment. The ability of these binding ADAs to neutralize tebentafusp-tebn is unknown. The tebentafusp-tebn clearance increased in patients with high titer ADAs [see Clinical Pharmacology (12.3)] . Exploratory analyses with limited data suggest that formation of ADA does not appear to have clinically significant effect on frequency or severity of hypersensitivity related adverse reactions and no observed sign of decreased overall survival.
Risk Summary
Based on the mechanism of action, KIMMTRAK may cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1)] . There are no available data with KIMMTRAK in pregnant woman. No animal reproductive and developmental toxicity studies have been conducted with KIMMTRAK. Molecules of similar molecular weight can cross the placenta resulting in fetal exposure. 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%-4% and 15%-20%, respectively.
Risk Summary
There are no data on the presence of tebentafusp-tebn in human milk, the effect on the breastfed child, or the effects on milk production. Because tebentafusp-tebn may be excreted in human milk and because of the potential for serious adverse reactions in a breastfed child, advise patients not to breastfeed during treatment with KIMMTRAK and for at least 1 week after the last dose.
KIMMTRAK may cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)] .
Pregnancy Testing
Verify pregnancy status in females of reproductive potential prior to initiating KIMMTRAK treatment.
Contraception
Females
Advise female of reproductive potential to use effective contraception during treatment and for 1 week following the last dose of KIMMTRAK [see Use in Specific Populations (8.1)] .
Of the 245 patients with metastatic uveal melanoma treated with KIMMTRAK on IMCgp100-202, 47% were 65 years of age and older and 9% were 75 years of age and older. No overall differences in safety or efficacy were observed between patients ≥ 65 years of age compared to younger adult patients.
Tebentafusp-tebn is a bispecific gp100 peptide-HLA-directed T cell receptor CD3 T cell engager. Tebentafusp-tebn has an approximate molecular weight of 77 kDa. Tebentafusp-tebn is produced by recombinant DNA technology in Escherichia colicells.
KIMMTRAK (tebentafusp-tebn) injection is supplied in a single-dose vial as a sterile, preservative-free, clear, colorless or slightly yellowish solution for intravenous administration by infusion.
Each single-dose vial contains tebentafusp-tebn (100 mcg), citric acid monohydrate (0.95 mg), di-sodium hydrogen phosphate (2.91 mg), mannitol (5 mg), polysorbate 20 (0.1 mg) trehalose (25 mg), and water for injection, with a pH of 6.5.
Tebentafusp-tebn is a bispecific gp100 peptide-HLA-A*02:01 directed T cell receptor CD3 T cell engager. The TCR arm binds to a gp100 peptide presented by human leukocyte antigen-A*02:01 (HLA-A*02:01) on the cell surface of uveal melanoma tumor cells.
In vitro, tebentafusp-tebn bound to HLA-A*02:01-positive uveal melanoma cells and activated polyclonal T cells to release inflammatory cytokines and cytolytic proteins, which results in direct lysis of uveal melanoma tumor cells.
Lymphocyte counts declined the day after the first 3 doses and returned to baseline prior to subsequent doses.
Serum levels of cytokines (IFN-γ, TNFα, IL-2, IL-6, IL-10 and IL-1RA) and chemokines (CXCL9, CXCL10, CXCL11, hepatocyte growth factor, and monocyte chemoattractant protein-1) were increased during the first three doses of KIMMTRAK with peak levels between 8 to 24 hours after treatment with KIMMTRAK and levels returned to baseline prior to subsequent doses. In subsequent treatment cycles, cytokine elevation occurred in fewer patients with lesser intensity compared to the first 3 doses.
The exposure-response relationship and time course of pharmacodynamic response for the safety and effectiveness of KIMMTRAK have not been fully characterized.
After a single dose administration, tebentafusp-tebn C maxand AUC 0-7dincreased in an approximately dose proportional manner from 20 to 68 mcg (0.3 to 1 times the approved recommended dose). Following administration of the approved recommended dosage in patients with metastatic uveal melanoma, the steady-state geometric mean (% CV) C maxof tebentafusp-tebn is 13 ng/mL (34.6%) and AUC 0-7dis 4.6 ng.day/mL (23%) with no accumulation.
Distribution
Tebentafusp-tebn geometric mean (% CV) steady-state volume of distribution is 7.56 L (24%).
Elimination
The geometric mean clearance of tebentafusp-tebn is 16.4 L/d (CV: 24.5%) and median terminal half-life is 7.5 hours (range: 6.8-7.5 hours).
Metabolism
Tebentafusp-tebn is expected to be catabolized into small peptides and amino acids.
Specific Populations
No clinically significant difference in the pharmacokinetics of tebentafusp-tebn were identified based on weight (43 to 163 kg), sex (48% female), age (23 to 91 years), or mild to moderate renal impairment based on creatinine clearance (CL cr) estimated by C-G formula (CL cr30 to 89 mL/min) or mild hepatic impairment as measured by total bilirubin (TB) and aspartate aminotransferase (AST) (TB ≤ upper limit of normal (ULN) and AST > ULN or TB > 1 to 1.5x ULN and any AST).
Tebentafusp-tebn has not been studied in patients with severe (CL cr< 30 mL/min) renal impairment or in patients with moderate (TB >1.5 to 3x ULN, any AST) to severe (TB > 3 to 10x ULN, any AST) hepatic impairment.
Immunogenicity
Median titer in the ADA-positive subgroup was 8192 across the 67 treatment cycles. The exposure (AUC 0-7 days) of tebentafusp-tebn decreased by 97% and terminal half-life decreased to 10-14 minutes in patients with ADA titers greater than 8192.
Drug Interaction
Elevation of certain proinflammatory cytokines may suppress CYP450 enzyme activities.
Study IMCgp100-202: First line metastatic uveal melanoma
KIMMTRAK was evaluated in IMCgp100-202, a randomized, open-label, multicenter trial (NCT03070392) that enrolled patients with metastatic uveal melanoma (N=378). Patients were required to be HLA-A*02:01 genotype positive identified by a central assay. Patients were excluded if they received prior systemic therapy for metastatic or advanced uveal melanoma or localized liver-directed therapy. Prior surgical resection of oligometastatic disease was permitted. Patients with clinically significant cardiac disease or the presence of symptomatic or untreated brain metastasis were excluded.
Patients were randomized (2:1) to receive KIMMTRAK weekly by intravenous infusion administered at 20 mcg intravenously on Day 1, 30 mcg intravenously on Day 8, 68 mcg intravenously on Day 15, and 68 mcg intravenously once every week thereafter (N=252) or Investigator’s choice (N=126) of pembrolizumab, ipilimumab, or dacarbazine. Randomization was stratified by lactate dehydrogenase (LDH) level at study entry. Across both arms, patients stopped treatment for disease progression, unless the patient was otherwise deriving benefit, or for unacceptable toxicity.
The major efficacy outcome was overall survival (OS). Additional efficacy outcomes were investigator-assessed progression free survival (PFS) and objective response rate (ORR) per RECIST 1.1.
The median age was 64 years (range 23 to 92 years); 50% were female; 87% were White, and 12% were unreported or unknown race. The reported ethnicity was Hispanic or Latino in 2.4% of patients. Baseline ECOG performance status was 0 (73%), 1 (21%), or 2 (0.3%); 36% had elevated LDH level; and 94% had liver metastasis.
The efficacy results are summarized in Table 6and Figure 1.
