[ 5 ] [ 18 ] It binds to plasma proteins at a rate of 99.5%; it has a low volume of distribution (9 L/kg) and is thus not extensively absorbed.
Clinical trial number NCT01566721 for "A Safety and Tolerability Study of Assisted and Self-Administered Subcutaneous (SC) Herceptin (Trastuzumab) as Adjuvant Therapy in Early Human Epidermal Growth Factor Receptor 2 (HER2)-Positive Breast Cancer (SafeHER)" at ClinicalTrials.gov
The threshold dose is only a measure of acute toxicity since the drug or toxic substance investigated is administered at once. The consequence of long-term administration remains unknown. [27] As the threshold dose is the measured minimal response, its accuracy heavily depends on the machinery used. It is possible that further refinement is ...
Pertuzumab is administered as an intravenous infusion in combination with trastuzumab and docetaxel as a first line treatment for HER2-positive metastatic breast cancer. [4] [3] It is also used in the same combination as a neoadjuvant (given to reduce the size of a tumor, prior to surgery or radiation) for HER2-positive early breast cancer; as of 2016 this use had not been shown to increase ...
Cancer immunotherapy (immuno-oncotherapy) is the stimulation of the immune system to treat cancer, improving the immune system's natural ability to fight the disease. [1] It is an application of the fundamental research of cancer immunology (immuno-oncology) and a growing subspecialty of oncology.
