1. Exclusions

   Aetna will not provide coverage for members who have experienced disease progression while on PD-1 or PD-L1 inhibitor therapy.

2. Criteria for Initial Approval

   1. Esophageal squamous cell carcinoma

      Aetna considers tislelizumab-jsgr (Tevimbra) medically necessary for the treatment of esophageal squamous cell carcinoma in members who are not surgical candidates or have unresectable, recurrent, or metastatic disease when the following criteria are met:

      1. The member has tried prior systemic chemotherapy not including a PD-L1 inhibitor; and
      2. The requested medication will be used as a single agent.

   2. Hepatocellular carcinoma

      Aetna considers tislelizumab-jsgr (Tevimbra) medically necessary as a single agent for the first line treatment of hepatocellular carcinoma when the member is deemed ineligible for resection, transplant, or locoregional therapy.

   Aetna considers all other indications as experimental, investigational, or unproven.

3. Continuation of Therapy

   Aetna considers continuation of tislelizumab-jsgr (Tevimbra) therapy medically necessary for treatment in members requesting reauthorization for an indication listed in Section II when there is no evidence of unacceptable toxicity or disease progression while on the current regimen.

Dosage and Administration

Tislelizumab-jsgr is supplied as Tevimbra injection 100 mg/10 mL (10 mg/mL) solution in a single-dose vial for intravenous infusion.

Esophageal Squamous Cell Carcinoma

The recommended dose of Tevimbra is 200 mg administered as an intravenous infusion once every 3 weeks, until disease progression or unacceptable toxicity. Administer the first infusion over 60 minutes. If tolerated, subsequent infusions may be administered over 30 minutes.

Background

U.S. Food and Drug Administration (FDA)-Approved Indications 

• Tevimbra as a single agent, is indicated for the treatment of adult patients with unresectable or metastatic esophageal squamous cell carcinoma after prior systemic chemotherapy that did not include a PD-(L)1 inhibitor.

Compendial Uses

• Esophageal squamous cell carcinoma
• Hepatocellular carcinoma

Tislelizumab-jsgr is available as Tevimbra (BeiGene USA, Inc.) and is a programmed death receptor-1 (PD 1)-blocking antibody. Tevimbra is an Fc-engineered humanized monoclonal IgG4 kappa antibody produced in recombinant Chinese hamster ovary (CHO) cells. Tevimbra binds to PD-1 ligands PD-L1 and PD-L2, to the PD-1 receptor found on T cells, which inhibits T-cell proliferation and cytokine production. PD-1 ligands are upregulated in some tumors and signaling through this pathway can contribute to inhibition of active T-cell immune surveillance of tumors (BeiGene USA, 2024).

Tevimbra, according to the prescribing information, carries the following warnings and precautions:

• Immune-mediated adverse reactions:

  • Immune-mediated adverse reactions can be severe or fatal and occur in any organ system or tissue, including the following: immune-mediated pneumonitis, immune-mediated colitis, immune-mediated hepatitis, immune-mediated endocrinopathies, immune-mediated nephritis with renal dysfunction, immune-mediated dermatologic adverse reactions, and solid organ transplant rejection.
  • Monitor for early identification and management. Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment.
  • Withhold or permanently discontinue Tevimbra based on the severity of reaction.
    
    
• Infusion-related reactions: Slow the rate of infusion, interrupt, or permanently discontinue based on severity of infusion reaction.
• Complications of allogeneic hematopoietic stem cell transplantation (HSCT): Fatal and other serious complications can occur in patients who receive allogeneic HSCT before or after being treated with a PD-1/PD-L1 blocking antibody.
• Embryo-fetal toxicity: Can cause fetal harm. Advise females of reproductive potential of the possible risk to a fetus and to use of effective contraception.

According to the prescribing information, the most common adverse reactions (≥ 20%), including laboratory abnormalities with Tevimbra are: increased glucose, decreased hemoglobin, decreased lymphocytes, decreased sodium, decreased albumin, increased alkaline phosphatase, anemia, fatigue, increased AST, musculoskeletal pain, decreased weight, increased ALT, and cough.

On March 13, 2024, the U.S. Food and Administration (FDA) approved tislelizumab-jsgr (Tevimbra) as single agent therapy for the treatment of adult patients with unresectable or metastatic esophageal squamous cell carcinoma (ESCC) after prior systemic chemotherapy that did not include a PD-L1 inhibitor. This FDA approval was based on supporting data from the RATIONALE-302 study, a multicenter, randomized, open-label phase III clinical trial (BeiGene, Ltd., 2024b).

In the RATIONALE-302 trial, Shen and colleagues (2022) evaluated the efficacy and safety of tislelizumab-jsgr (Tevimbra) in adult patients with unresectable advanced or metastatic ESCC who progressed on or after prior systemic chemotherapy. In total, 512 patients were randomized (1:1) to receive intravenous Tevimbra 200 mg every 3 weeks (n=256) or investigator's choice of chemotherapy (ICC) (n=256; paclitaxel (33%), docetaxel (21%), or inrinotecan (46%)). Patients were treated until disease progression assessed by the investigator or unacceptable toxicity.

The primary efficacy endpoint measure was overall survival (OS) in the Intent-to-Treat (ITT) population. Secondary efficacy endpoint measures included investigator-assessed progression-free survival (PFS), overall response rate (ORR), and duration of response (DOR) per Response Evaluation Criteria in Solid Tumours version 1.1 (RECIST v1.1) (BeiGene USA, 2024a).

The investigators conducted a final analysis after 410 death events occurred and reported that OS was significantly longer with Tevimbra versus chemotherapy in all patients (median, 8.6 months versus 6.3 months; hazard ratio [HR], 0.70 [95% confidence interval (CI), 0.57 to 0.85]; p = 0.0001). Patients in the Tevimbra treatment arm experienced a higher objective response rate (15.2%; 95% CI [11.1, 20.2]) compared to patients in the ICC arm (6.6%; 95% CI [3.9, 10.4]). The median duration of response was 10.3 months (6.5, 13.2) versus 6.3 months (2.8, 8.5), respectively. Fewer patients experienced ≥ grade 3 treatment-related adverse events (18.8% versus 55.8%) with Tevimbra compared to ICC (BeiGene USA, 2024a).

The RATIONALE-302 study demonstrated a statistically significant improvement in OS in patients who received Tezimbra compared with ICC. The investigators concluded that Tezimbra significantly improved OS compared with chemotherapy as second-line therapy in patients with advanced or metastatic ESCC, with a tolerable safety profile (Shen et al., 2022).
