What is Kimmtrak?
From the FDA label: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 coli cells. 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.
How to use
Recommended dosage: 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 ( 2.2 ). Dilute and administer by intravenous infusion over 15-20 minutes ( 2.2 , 2.4 ). See Full Prescribing Information for instructions on preparation and administration of the diluted solution for intravenous infusion ( 2.2 , 2.4 ). Dosage interruption or permanent discontinuation may be required based on individual safety and tolerability ( 2.3 ). 2.1 Patient Selection Select patients for treatment of unresectable or metastatic uveal melanoma with KIMMTRAK based on a positive HLA-A*02:01 genotyping test of a whole blood sample [see Clinical Studies (14) ] . Information on FDA-approved tests is available at http://www.fda.gov/companiondiagnostics . 2.2 Recommended Dosage The recommended dosage of KIMMTRAK administered intravenously is: 20 mcg on Day 1 30 mcg on Day 8 68 mcg on Day 15 68 mcg once every week thereafter Treat patients until unacceptable toxicity or disease progression occur. Administer the first three infusions of KIMMTRAK in an appropriate healthcare setting by intravenous infusion over 15-20 minutes. Monitor patients during the infusion and for at least 16 hours after the infusion is complete. If the patient does not experience Grade 2 or worse hypotension (requiring medical intervention)…
Side effects
The following serious adverse reactions are discussed in greater detail in other sections of the label: Cytokine Release Syndrome [ see Boxed Warning , Warnings and Precautions (5.1) ] Skin Reactions [ see Warnings and Precautions (5.2) ] Elevated Liver Enzymes [ see Warnings and Precautions (5.3) ] The most common adverse reactions (occurring in ≥ 30%) are cytokine release syndrome, rash, pyrexia, pruritus, fatigue, nausea, chills, abdominal pain, edema, hypotension, dry skin, headache and vomiting ( 6.1 ). The most common laboratory abnormalities (occurring in ≥50%) are decreased lymphocyte count, increased creatinine, increased glucose, increased aspartate aminotransferase, increased alanine aminotransferase, decreased hemoglobin, and decreased phosphate ( 6.1 ). To report SUSPECTED ADVERSE REACTIONS, contact Immunocore at 1-844-IMMUNO1 (1-844-466-8661) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 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. 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…
FDA Boxed Warning (the FDA’s most serious warning)
Boxed (black-box) warning — from the FDA label
Cytokine Release Syndrome (CRS), which may be serious or life-threatening, occurred in patients receiving KIMMTRAK. Monitor for at least 16 hours following first three infusions and then as clinically indicated [(see Dosage and Administration (2.2) , see Warnings and Precautions (5.1) ] . WARNING: CYTOKINE RELEASE SYNDROME Cytokine Release Syndrome (CRS), which may be serious or life-threatening, occurred in patients receiving KIMMTRAK. Monitor for at least 16 hours following first three infusions and then as clinically indicated ( 2.2 , 5.1 ).
Warnings
Important safety information
Skin reactions : Rash, pruritus, and cutaneous edema occurred in patients treated with KIMMTRAK. If skin reactions occur, treat based on persistence and severity of symptoms ( 2.3 , 5.2 ). Elevated liver enzymes : Elevations in liver enzymes occurred in patients treated with KIMMTRAK. Monitor ALT, AST, and total bilirubin ( 2.3 , 5.3 ). Embryo-Fetal toxicity : May cause fetal harm. Advise patients of reproductive potential of the potential risk to the fetus and to use effective contraception ( 5.4 , 8.1 , 8.3 ). 5.1 Cytokine Release Syndrome 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) ] . 5.2 Skin Reactions 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) ] . 5.3 Elevated Liver Enzymes 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) ] . 5.4 Embryo-Fetal Toxicity 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) ] .
