Historically, there have been no FDA-approved treatments indicated for mUM‍—‍until now2-4

Neither checkpoint inhibitors nor other systemic therapies for mCM are FDA approved in mUM.2-4

Patients have faced a dismal prognosis, with a post-diagnosis median survival of approximately 9-16 months.2,5-9 NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines®) recommend enrollment in an investigational clinical trial, if appropriate, as a preferred option.1

Now tebentafusp-tebn (KIMMTRAK) is included as a category 1* preferred treatment option for HLA-A*02:01-positive adult patients with unresectable or metastatic uveal melanoma.1

* Category 1: Based upon high-level evidence, there is uniform NCCN consensus that the intervention is appropriate.

Mechanism of Action Icon

MECHANISM OF ACTION

Proposed mechanism of action

KIMMTRAK is a first-in-class T cell engager directed against mUM2,*

  • KIMMTRAK is a bispecific T cell engager that redirects the immune system to target and kill gp100-expressing uveal melanoma tumor cells. Gp100 is expressed via HLA-A*02:01 on most uveal melanoma cells2,10
  • KIMMTRAK has 1 million–fold greater affinity for gp100 presented by HLA-A*02:01 than natural T cell receptors11,12
  • KIMMTRAK binds to uveal melanoma cells and cytotoxic T cells, forming an immune synapse2
  • The T cells become activated, releasing cytokines to attract more T cells and lytic granules to contribute to tumor cell death; normal melanocytes could also be targeted2,10,13

* Based on in vitro and in vivo studies.2,10,13

Consider a blood test for your patients with mUM to determine their HLA status and if KIMMTRAK is right for them2

STUDY RESULTS

KIMMTRAK was proven to extend median overall survival (OS) by 6 months vs checkpoint inhibitors or chemotherapy in first-line2,7

Improved OS was seen in a pivotal phase 3 trial of 378 HLA-A*02:01-positive adult patients with mUM treated with KIMMTRAK in first-line (HR = 0.51; 95% CI, 0.37-0.71; P < 0.0001), compared with investigator’s choice of pembrolizumab, ipilimumab, or dacarbazine.

Primary end point: overall survival

a probability of survival chart which includes time from randomization information. The chart shows results over 36 months

43% of patients received treatment with KIMMTRAK beyond initial progression, with no new safety signals identified. Median duration of KIMMTRAK treatment beyond initial progression was 8 weeks. Of the total KIMMTRAK infusions during the study, 22% were administered after initial progression14

In clinical trials, patients stopped treatment for disease progression,* unless they were otherwise deriving benefit, or for unacceptable toxicity.2

* Two scans were required to confirm progression.16 Further progressive disease warranting treatment discontinuation is defined as ANY of the following observed at least 4 weeks post initial progressive disease assessment: an additional >20% increase in tumor burden (with an absolute increase of >5 mm), unequivocal progressive disease of nontarget lesion, or new nonmeasurable lesions.15

Largest phase 3 clinical trial in mUM compared KIMMTRAK to checkpoint inhibitors or chemotherapy in first-line2

An international, multicenter, pivotal, phase 3, 2:1 randomized, controlled trial of 378 HLA-A*02:01-positive adult patients with metastatic uveal melanoma compared KIMMTRAK with investigator’s choice of pembrolizumab, ipilimumab, or dacarbazine.2,7,16

SAFETY

Low 3.3% discontinuation rate with KIMMTRAK2

KIMMTRAK adverse events were predictable and manageable* with 3.3% of patients discontinuing treatment due to adverse events (AEs)2,7

  • In clinical trials, cytokine release syndrome (CRS), skin reactions, and elevated liver enzymes occurred following KIMMTRAK infusion.2 These events decreased in frequency and severity after the first 3 doses7
  • 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 vomiting2

* CRS symptoms were generally reversible and managed with IV fluids, NSAIDs, a single dose of corticosteroids, oxygen, and rarely, a vasopressor.2,7 Monitor fluid status, vital signs, and oxygenation level and provide appropriate therapy.2

  2. Represents a composite of multiple related terms.

Clinically relevant adverse reactions occurring in <20% of patients who received KIMMTRAK included back pain, decreased appetite, constipation, hypertension, tachycardia or sinus tachycardia, dyspnea, paresthesia, dizziness, flushing, muscle spasms, myalgia, pain in extremity, alopecia, skin hyperpigmentation, influenza-like illness, oropharyngeal pain, and night sweats.

Rash tended to occur early in treatment, decreased in incidence and severity, and was associated with 27-month median overall survival (mOS)2,7

  • Severity and frequency of rash generally decreased following each of the first 3 infusions7
  • Rash is thought to be due to on-target off-tumor activity of KIMMTRAK against gp100-expressing healthy melanocytes in skin, consistent with the proposed mechanism of action2,7

  • Rash is not an independent predictor of overall survival; most patients will have a rash at some point during treatment, and some patients without a rash may also benefit7
Dosing and Administration Icon

DOSING AND ADMINISTRATION

KIMMTRAK is administered once weekly via continuous IV infusion over 15‑20 minutes2

Adequate hydration/euvolemic status prior to starting KIMMTRAK is advised

  1. If patient has not had a ≥grade 2 cytokine release syndrome adverse event with their previous dose.14
  2. If patient has not had hypotension requiring medical intervention with their most recent dose.2
  3. Adjustment in what to monitor and at what frequency can be made using clinical judgment or by institutional standards. Recommendations above based on clinical trial protocol.17

CRS management recommendations

No dosage reduction for KIMMTRAK is recommended. For specific dosage modifications please refer to Section 2.3, Table 1 in full Prescribing Information2

A rise in temperature is generally the first sign of CRS, occurring earlier than drops in blood pressure.2 Once fever is detected, patients should be monitored more closely for changes in other vital signs like pulse rate, respiratory rate, and blood pressure.2 Consider managing symptoms early to help prevent CRS from escalating.

Patients who may be sensitive to manifestations of CRS, such as hypotension, tachycardia, or hypoxia, or the use of intravenous fluids to manage CRS, should be carefully assessed prior to starting KIMMTRAK. Ensure patients are euvolemic prior to initiating KIMMTRAK infusions.2

KIMMTRAK is a bispecific gp100 peptide-HLA-directed CD3 T cell engager indicated for the treatment of HLA-A*02:01-positive adult patients with unresectable or metastatic uveal melanoma.

Important Safety Information Including Boxed Warning

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. Manifestations of CRS may include fever, hypotension, hypoxia, chills, nausea, vomiting, rash, elevated transaminases, fatigue, and headache. CRS occurred in 89% of patients who received KIMMTRAK with 0.8% being grade 3 or 4. Ensure 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. Monitor fluid status, vital signs, and oxygenation level and provide appropriate therapy. Withhold or discontinue KIMMTRAK depending on persistence and severity of CRS.

Skin Reactions

Skin reactions, including rash, pruritus, and cutaneous edema occurred in 91% of patients treated with KIMMTRAK. 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.

Elevated Liver Enzymes

Elevations in liver enzymes occurred in 65% of patients treated with 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.

Embryo-Fetal Toxicity

KIMMTRAK may cause fetal harm. Advise pregnant patients of potential risk to the fetus and patients of reproductive potential to use effective contraception during treatment with KIMMTRAK and 1 week after the last dose.
