TELISOTUZUMAB VEDOTIN-TLLV INJ,LYPHL
Clinical Criteria Summary
Document 806
Indication & Patient Selection
- Previously treated patients with locally advanced or metastatic non-small cell lung cancer (NSCLC)
- High c-Met protein overexpression [≥50% of tumor cells with strong (3+) staining]
- Currently approved under accelerated approval
Dosing & Administration
- 1.9 mg/kg intravenously every 2 weeks
- Continue until disease progression or unacceptable toxicity
- Available as 20 mg or 100 mg telisotuzumab vedotin as lyophilized powder in a single-dose vial
Monitoring & Precautions
- Monitor for vision changes, dry eye, and other ocular symptoms; hold or consider discontinuation according to severity
- Ensure adequate venous access or administer via central line to reduce discomfort associated with infusion
- Assess ECOG performance status (0-1) and prior systemic therapy lines (1-2 lines, including 1 line of cytotoxic chemotherapy)
Warnings & Contraindications
- No boxed warnings or contraindications listed
- Embryo-fetal toxicity: Can cause fetal harm in a pregnant woman; advise effective contraception
- Peripheral neuropathy: Occurred in 51% of patients (11% grade 3); led to discontinuation in 13%
- ILD/pneumonitis: Occurred in 10% of patients (3% grade 3, 0.6% grade 4); led to discontinuation in 7%
- Infusion-related reactions: Occurred in 3% of patients (1.2% grade 3, 0.6% grade 4); led to discontinuation in 0.6%
Adverse Events & Management
- Pre-medications recommended for patients who experience an infusion-related reaction (administered 30-60 minutes prior to subsequent infusions): Diphenhydramine 25-50mg PO/IV, Famotidine 20mg PO/IV, Acetaminophen 650-1,000mg PO/IV, Methylprednisolone 125mg IV (or equivalents)
- Adverse events occurring in ≥20% of patients: decreased albumin, increased glucose, peripheral neuropathy, decreased calcium, increased ALT, decreased lymphocytes, increased GGT, decreased hemoglobin, increased AST, decreased phosphorous/sodium, increased alkaline phosphatase, fatigue, peripheral edema, decreased appetite
- Fatal events (5%): ILD/pneumonitis, pneumonia, sudden death, noninfectious endocarditis, myocardial infarction
Exclusion Criteria
- Radiation therapy to the lungs within 6 months
- History of interstitial lung disease (ILD) or pneumonitis requiring steroids, or prior ILD or pneumonitis within 3 months
- Unresolved grade ≥2 adverse events
- Major surgery within 3 weeks
VA-Specific Considerations
- c-Met protein expression is not currently routinely evaluated in VHA
- Risk vs. benefit analysis should be considered due to notable incidence of fatal adverse events and pending phase III data (TeliMET NSCLC-01)
- Currently not listed in VA Oncology Clinical Pathways; c-Met overexpression not mentioned in pathways
Document 825
Exclusion Criteria
- Absolute neutrophil count (ANC) <1,000/mm3 (unless Duffy null phenotype), platelets <100,000/mm3
- CrCl <30 mL/minute
- Moderate or severe hepatic impairment: total bilirubin >1.5 times ULN and any AST or with liver metastases: total bilirubin >1.5 times ULN, or AST or ALT >5 times ULN
- Symptomatic or unstable brain metastases
- History of interstitial lung disease (ILD) or pneumonitis requiring steroids, or prior ILD or pneumonitis within 3 months
- Evidence of pulmonary fibrosis
- Grade ≥2 or history of Grade ≥3 peripheral neuropathy
- Known pregnancy
- Lactating
Inclusion Criteria
- Locally-advanced or metastatic non-squamous EGFR-wildtype non-small cell lung cancer (NSCLC)
- High c-Met protein overexpression (≥50% of tumor cells with strong 3+ staining)
- Progression on prior systemic cytotoxic chemotherapy and immunotherapy
Care Setting & Performance Status
- Care provided by a VA/VA Community Care oncology provider
- Eastern Cooperative Oncology Group (ECOG) performance status 0-1
- Goals of care and role of Palliative Care consult discussed and documented
Reproductive Health & Counseling Requirements
- For females who can become pregnant and males with partners who can become pregnant: Counseling provided on potential risks vs benefits of treatment and use of effective contraception during therapy and for 2 months after stopping treatment for women and 4 months after for men.
