Tarceva information for pharmacists
The recommended daily dose of Tarceva for metastatic NSCLC is 150 mg taken once daily. Take Tarceva on an empty stomach (ie, at least one hour
before or two hours after the ingestion of food). Treatment should continue until disease progression or unacceptable toxicity
Tarceva is a Human Epidermal Growth Factor Receptor Type 1/Epidermal Growth Factor Receptor (HER1/EGFR) tyrosine kinase inhibitor. Tarceva tablets are
available in 3 dosage strengths containing erlotinib hydrochloride equivalent to 150 mg, 100 mg, and 25 mg.1
Per agreement with customer's wholesaler.
Store at 25°C (77°F); excursions permitted to 15-30°C (59-86°F). See USP Controlled Room Temperature.
Tarceva is indicated for:
- The treatment of patients with metastatic non-small cell lung cancer (NSCLC) whose tumors have epidermal growth factor receptor (EGFR) exon 19 deletions or exon 21 (L858R) substitution mutations as detected by an FDA-approved test receiving first-line, maintenance, or second or greater line treatment after progression following at least one prior chemotherapy regimen.
Limitations of use:
- Safety and efficacy of Tarceva have not been established in patients with NSCLC whose tumors have other EGFR mutations.
- Tarceva is not recommended for use in combination with platinum-based chemotherapy.
For more information, please see Tarceva full Prescribing Information.
WARNINGS AND PRECAUTIONS
- Interstitial Lung Disease (ILD):
- Cases of serious ILD, including fatal cases, can occur with Tarceva treatment. The overall incidence of ILD in approximately 32,000 Tarceva-treated patients in uncontrolled studies and studies with concurrent chemotherapy was approximately 1.1%. In patients with ILD, the onset of symptoms was between 5 days to more than 9 months (median 39 days) after initiating Tarceva therapy.
- Withhold Tarceva for acute onset of new or progressive unexplained pulmonary symptoms such as dyspnea, cough, and fever pending diagnostic evaluation. If ILD is confirmed, permanently discontinue Tarceva.
- Renal Failure:
- Hepatorenal syndrome, severe acute renal failure including fatal cases, and renal insufficiency can occur with Tarceva treatment. Renal failure may arise from exacerbation of underlying baseline hepatic impairment or severe dehydration.
- The pooled incidence of severe renal impairment in the 3 monotherapy lung cancer studies was 0.5% in the Tarceva arms and 0.8% in the control arms. The incidence of renal impairment in the pancreatic cancer study was 1.4% in the Tarceva plus gemcitabine arm and 0.4% in the control arm.
- Withhold Tarceva in patients developing severe renal impairment until renal toxicity is resolved. Perform periodic monitoring of renal function and serum electrolytes during Tarceva treatment.
- Hepatotoxicity With or Without Hepatic Impairment:
- Hepatic failure and hepatorenal syndrome, including fatal cases, can occur with Tarceva treatment in patients with normal hepatic function; the risk of hepatic toxicity is increased in patients with baseline hepatic impairment.
- Hepatic Toxicity: One Tarceva-treated patient experienced fatal hepatic failure and four additional patients experienced grade 3-4 liver test abnormalities.
- In clinical studies where patients with moderate to severe hepatic impairment were excluded, the pooled incidence of hepatic failure in the 3 monotherapy lung cancer studies was 0.4% in the Tarceva arms and 0% in the control arms. The incidence of hepatic failure in the pancreatic cancer study was 0.4% in the Tarceva plus gemcitabine arm and 0.4% in the control arm.
- Perform periodic liver testing (transaminases, bilirubin, and alkaline phosphatase) during treatment with Tarceva. Increased frequency of monitoring of liver function is required for patients with pre-existing hepatic impairment or biliary obstruction.
- Withhold Tarceva in patients without pre-existing hepatic impairment for total bilirubin >3 x ULN or transaminases >5 x ULN. Withhold Tarceva in patients with pre-existing hepatic impairment or biliary obstruction for doubling of bilirubin or tripling of transaminases values over baseline.
- Discontinue Tarceva in patients whose abnormal liver tests meeting the above criteria do not improve significantly or resolve within 3 weeks.
- Gastrointestinal Perforation:
- Gastrointestinal perforation, including fatal cases, can occur with Tarceva treatment. Patients receiving concomitant anti-angiogenic agents, corticosteroids, NSAIDs, or taxane-based chemotherapy, or who have prior history of peptic ulceration or diverticular disease may be at increased risk of perforation.
- The pooled incidence of gastrointestinal perforation in the 3 monotherapy lung cancer studies was 0.2% in the Tarceva arms and 0.1% in the control arms. The incidence of gastrointestinal perforation in the pancreatic cancer study was 0.4% in the Tarceva plus gemcitabine arm and 0% in the control arm.
- Permanently discontinue Tarceva in patients who develop gastrointestinal perforation.
- Bullous and Exfoliative Skin Disorders:
- Bullous, blistering and exfoliative skin conditions, including cases suggestive of Stevens-Johnson syndrome/toxic epidermal necrolysis, which in some cases were fatal, can occur with Tarceva treatment.
- The pooled incidence of bullous and exfoliative skin disorders in the 3 monotherapy lung cancer studies was 1.2% in the Tarceva arms and 0% in the control arms. The incidence of bullous and exfoliative skin disorders in the pancreatic cancer study was 0.4% in the Tarceva plus gemcitabine arm and 0% in the control arm.
- Discontinue Tarceva treatment if the patient develops severe bullous, blistering or exfoliating conditions.
- Cerebrovascular Accident:
- In the pancreatic carcinoma trial, 7 patients in the Tarceva plus gemcitabine group developed cerebrovascular accidents (incidence: 2.5%). One of these was hemorrhagic and was the only fatal event. In comparison, in the placebo plus gemcitabine group there were no cerebrovascular accidents. The pooled incidence of cerebrovascular accident in the 3 monotherapy lung cancer studies was 0.6% in the Tarceva arms and not higher than that observed in the control arms.
- Microangiopathic Hemolytic Anemia With Thrombocytopenia:
- The pooled incidence of microangiopathic hemolytic anemia with thrombocytopenia in the 3 monotherapy lung cancer studies was 0% in the Tarceva arms and 0.1% in the control arms. The incidence of microangiopathic hemolytic anemia with thrombocytopenia in the pancreatic cancer study was 1.4% in the Tarceva plus gemcitabine arm and 0% in the control arm.
- Ocular Disorders:
- Decreased tear production, abnormal eyelash growth, keratoconjunctivitis sicca or keratitis can occur with Tarceva treatment and can lead to corneal perforation or ulceration.
- The pooled incidence of ocular disorders in the 3 monotherapy lung cancer studies was 17.8% in the Tarceva arms and 4% in the control arms. The incidence of ocular disorders in the pancreatic cancer study was 12.8% in the Tarceva plus gemcitabine arm and 11.4% in the control arm.
- Interrupt or discontinue Tarceva therapy if patients present with acute or worsening ocular disorders such as eye pain.
- Hemorrhage in Patients Taking Warfarin:
- Severe and fatal hemorrhage associated with International Normalized Ratio (INR) elevations can occur when Tarceva and warfarin are administered concurrently.
- Regularly monitor prothrombin time and INR during Tarceva treatment in patients taking warfarin or other coumarin-derivative anticoagulants.
- Embryo-Fetal Toxicity:
- Based on animal data and its mechanism of action, Tarceva can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus.
- Advise females of reproductive potential to use effective contraception during therapy and for one month after the last dose of Tarceva.
MOST COMMON ADVERSE REACTIONS
- Metastatic NSCLC – First-Line Treatment of Patients With EGFR Mutations:
- Most frequent (≥30%) adverse reactions were diarrhea, asthenia, rash, cough, dyspnea, and decreased appetite.
- Most frequent Grade 3/4 (NCI-CTC Version 3.0) adverse reactions were rash (14%) and diarrhea (5%). In Tarceva-treated patients, the most frequently reported adverse reactions leading to dose modification were rash (13%), diarrhea (10%), and asthenia (3.6%).
