To determine 3-year IDFS (invasive disease-free survival), DDFS (distant disease-free survival), DRFS (distant relapse-free survival), RFI (recurrence-free interval), OS (overall survival) and breast cancer-specific survival in patients who achieve pCR (and by pretreatment clinical stage).

To determine if 3-year recurrence-free survival (RFS) is greater than 92% among clinical stages II or IIIa patients with HER2-positive breast cancer who achieve pathologic complete response (pCR) (ypT0/is ypN0) after preoperative therapy with 12 weeks of a taxane, trastuzumab (or Food and Drug Administration approved biosimilar) and pertuzumab (THP x 12). Giving paclitaxel, trastuzumab, and pertuzumab may enable fewer chemotherapy drugs to be given without compromising patient outcomes compared to the usual treatment. When these drugs attach to HER2 receptors, the signals that tell the cells to grow are blocked and the tumor cell may be marked for destruction by the body's immune system. Trastuzumab and pertuzumab are both a form of "targeted therapy" because they work by attaching themselves to specific molecules (receptors) on the surface of tumor cells, known as HER2 receptors. Drugs used in chemotherapy, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.
#T DM1 CLINICAL TRIALS TRIAL#
This trial studies how well paclitaxel, trastuzumab, and pertuzumab work in eliminating further chemotherapy after surgery in patients with HER2-positive stage II-IIIa breast cancer who have no cancer remaining at surgery (either in the breast or underarm lymph nodes) after pre-operative chemotherapy and HER2-targeted therapy. It gives the opportunity to be normal women and mothers and wives.Recruitment Status, Study Status, Contacts/Locations and OversightĬontacts/Locations, Study Status and Eligibility "We need more options for women with stage 4 breast cancer, and this is a wonderful option. "It gave me more time with my husband," she said. Although her cancer once again started to progress, she is grateful for the nine months it didn't. Not everyone, butfor some it is amazing."įor Spence, the new drug meant she could live a normal life. "I have been using the drug on clinical trials for six years, and we have patients who have been on it for two years, three years. "It has been shown to be effective when other standard treatments have stopped working, and it has great promise as a drug to be used earlier in the course of the disease," Winer said. Eric Winer, director of the breast oncology center at Dana Farber Cancer Institute, said the effectiveness of the drug, paired with its low side effect profile, could be a boon for many patients. "We don't have evidence of a significant improvement in overall survival so we're not curing people, but if you're going to be treated, this has real benefits."ĭr. "It may not be the cure for this cancer and may represent one chapter in a fairly long book for people who have metastatic breast cancer, but it's a new and additional option." Clifford Hudis, chief of the Breast Cancer Medicine Service at Memorial Sloan-Kettering Cancer Center, who was not involved with the study. "We're getting responses that are looking better than at least one conventional choice and a toxicity profile that is better," said Dr. Not a Cure, But a Step Forwardįor a notoriously aggressive cancer such as HER2-positive breast cancer, the study findings are encouraging.

"This can really have an impact on patient's lives," she said.īecause of the linkage between the drugs, the chemotherapy is not activated until T-DM-1 gets inside the cancer cells, she explained, leading to fewer side effects. With T-DM1, she added, women didn't even lose their hair, and experienced far fewer other side effects. In many drug trials with improved outcomes, we see worse effects, but in this trial, we use two drugs, see better outcomes and have better quality of life measures," said Blackwell. "This is very unusual for cancer drug trials.

There have been early drug trials evaluating the effects of DM1 alone, but Hurvitz said the drug was too toxic, so far unlike the combination agent T-DM1. "Herceptin is linked in a very stable fashion to a highly cytotoxic chemotherapy drug, which is highly potent." "This is a very nice molecule that targets HER2-positive breast cancer," Hurvitz said. The patients who received T-DM1 also experienced fewer side effects, which is also a very important finding. Sara Hurvitz, a study investigator and director of the Breast Oncology Program at UCLA's Jonsson Comprehensive Cancer Center said it can give an early indication of how well a drug is working. There is considerable debate among clinicians about using progression-free survival to measure a drug's effectiveness, but Dr.
