7 Drug Interactions

Additions and revisions underlined:

Anthracyclines

Patients who receive anthracycline after stopping Herceptin may be at increased risk of cardiac dysfunction because of trastuzumab’s estimated long washout period [see Clinical Pharmacology (12.3)]. If possible, avoid anthracycline-based therapy for up to 7 months after stopping Herceptin. If anthracyclines are used, closely monitor the patient’s cardiac function.

8 Use in Specific Populations

8.1 Pregnancy

Additions and revisions underlined:

In post-marketing reports and published literature, use of Herceptin during pregnancy resulted in cases of oligohydramnios and of oligohydramnios sequence. Fetal manifestations included pulmonary hypoplasia, skeletal abnormalities, and neonatal death. These case reports described oligohydramnios in pregnant women who received Herceptin either alone or in combination with chemotherapy. In most reported cases, amniotic fluid index increased after Herceptin was stopped. In reported cases where Herceptin therapy was resumed after amniotic index improved, oligohydramnios recurred.

8.5 Geriatric Use

Additions and revisions underlined:

Herceptin has been administered to 386 patients who were 65 years of age or over (253 in the adjuvant treatment and 133 in metastatic breast cancer treatment settings). The risk of cardiac dysfunction was increased in geriatric patients as compared to younger patients in both those receiving treatment for metastatic disease in H0648g and H0649g, or adjuvant therapy in NSABP B31 and NCCTG N9831.

. . .

In ToGA (metastatic gastric cancer), of the 294 patients treated with Herceptin, 108 (37%) were 65 years of age or older, while 13 (4.4%) were 75 and over. No overall differences in safety or effectiveness were observed.

6 Adverse Reactions

6.3 Post-Marketing Experience

(Additions and/or revisions are underlined)

  • Tumor lysis syndrome (TLS): Cases of possible TLS have been reported in patients treated with Herceptin. Patients with significant tumor burden (e.g. bulky metastases) may be at a higher risk. Patients could present with hyperuricemia, hyperphosphatemia, and acute renal failure which may represent possible TLS. Providers should consider additional monitoring and/or treatment as clinically indicated.

Verify the pregnancy status of females of reproductive potential prior to the initiation of Herceptin. Advise pregnant women and females of reproductive potential that exposure to Herceptin during pregnancy or within 7 months prior to conception can result in fetal harm. Advise females of reproductive potential to use effective contraception during treatment and for 7 months following the last dose of Herceptin.
