Pregnancy

Pregnancy

Based on its mechanism of action, can cause fetal harm when administered during pregnancy; advise females of reproductive potential to use effective contraception during treatment and for at least 5 months following the last dose

Based on animal studies, atezolizumab may impair fertility in females of reproductive potential while receiving treatment

Lactation

Unknown if distributed in human breast milk

Advise lactating woman not to breastfeed during treatment and for at least 5 months after the last dose

Pregnancy Categories

A:Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

B:May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

C:Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

D:Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

X:Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

NA:Information not available.

What should I discuss with my healthcare provider before receiving atezolizumab?

You should not use atezolizumab if you are allergic to it.

To make sure atezolizumab is safe for you, tell your doctor if you have:

  • an active infection;

  • an immune system disorder such as lupus, ulcerative colitis, or Crohn's disease;

  • a history of organ transplant;

  • a breathing disorder;

  • liver disease; or

  • a nervous system disorder such as myasthenia gravis or Guillain Barré syndrome.

Do not use atezolizumab if you are pregnant. It could harm the unborn baby. Use effective birth control to prevent pregnancy while you are using this medicine and for at least 5 months after your last dose.

It is not known whether atezolizumab passes into breast milk or if it could harm a nursing baby. You should not breast-feed while using this medicine or within 5 months after your last dose. If you use a breast pump during this time, throw out any milk you collect. Do not feed it to your baby.

Atezolizumab Pregnancy Warnings

This drug should be used during pregnancy only if the benefit outweighs the risk. AU TGA pregnancy category: D US FDA pregnancy category: Not assigned. Risk Summary: -Based on animal studies, this drug impairs fertility in females of reproductive potential. -Based on its mechanism of action, this drug can cause harm to a developing fetus.

Animal reproduction studies have not been conducted to evaluate the effect on reproduction and fetal development. A literature-based assessment of the effects on reproduction demonstrated that a central function of the PD-L1/PD-1 pathway is to preserve pregnancy by maintaining maternal immune tolerance to a fetus. Blockage of PD-L1 signaling has been shown to disrupt tolerance to a fetus and to result in an increase in fetal loss. There are no controlled data in human pregnancy. It is not known whether this drug can cause fetal harm or adversely affect reproductive capacity in humans. AU TGA pregnancy category D: Drugs which have caused, are suspected to have caused or may be expected to cause, an increased incidence of human fetal malformations or irreversible damage. These drugs may also have adverse pharmacological effects. Accompanying texts should be consulted for further details. US FDA pregnancy category Not Assigned: The US FDA has amended the pregnancy labeling rule for prescription drug products to require labeling that includes a summary of risk, a discussion of the data supporting that summary, and relevant information to help health care providers make prescribing decisions and counsel women about the use of drugs during pregnancy. Pregnancy categories A, B, C, D and X are being phased out.
