Effective January 27, 2017, the Office of Environmental Health Hazard Assessment (OEHHA) is adding Pertuzumab (CAS No. 380610-27-5) to the list of chemicals known to the state to cause reproductive toxicity (developmental endpoint), and Vismodegib (CAS No. 879085-55-9) to the list of chemicals known to the state to cause reproductive toxicity (developmental, female and male endpoints), for purposes of Proposition 65^[1].  

As provided under Proposition 65, the listing of pertuzumab and vismodegib is based on a formal requirement by the US Food and Drug Administration (FDA) that the chemicals be identified or labeled as causing reproductive toxicity^[2].  Pertuzumab has been identified or labeled to communicate a risk of reproductive harm (developmental endpoint) in accordance with formal FDA requirements.  Vismodegib has been identified or labeled to communicate a risk of reproductive harm (developmental, female, and male endpoints) in accordance with formal FDA requirements.  Regulations governing the listing of chemicals under the “formally required to be labeled or identified” mechanism are published in Title 27, California Code of Regulations, section 25902.

The documentation supporting OEHHA’s determination that pertuzumab meets the criteria for listing is included in the Notice of Intent to List Pertuzumab posted on OEHHA’s website and published in the December 2, 2016 issue of the California Regulatory Notice Register (Register 2016, No. 49-Z^)[3].  No public comments were received.
