Other Chemo drugs that might be used. Chemo drugs may be paired with Herceptin, some probaly dependent on ER status.
Navelbine         =        vinorelbine

Combinations:
FIRST-LINE THERAPY 
Taxotere + Carboplatin + Herceptin
Taxotere + Herceptin + Perjeta
Taxol + Herceptin
Herceptin + Perjeta
ASCO (American Society of Clinical Oncology) recommends stopping the taxane after 6 months of stable disease and continuing Perjeta + Herceptin.
If progression occurs without the taxane, it is recommended that the taxane is resumed or to start second-line therapy. 
Current Study:  PERUSE study evaluating Perjeta, Herceptin, and a taxane.
Taxanes are: Paclitaxel, (Taxol), Docetaxel (Taxotere) or Nabpaclitaxel (Abraxane)

SECOND-LINE THERAPY
T-DM1 (Kadcyla) alone

THIRD-LINE THERAPY and LATER LINES-no recommended regimens
Tykerb (lapatinab) + Xeloda (capecitabine)
Tykerb + Herceptin
Tykerb + Letrozole (Aromatase Inhibitor usually used with hormone positive cancer.)
Tykerb and Herceptin
Certain chemos with Herceptin


Her 2 neu drugs undergoing trials

January 2017 - onclive.com Phase III SOPHIA trial ( NCT02492711), drug margetuximab paired with herceptin or chemotherapy of physicians choice: capecitabine, gemcitabine, vinorelbine, eribulin. Enter trial after prior treatment with herceptin, perjeta, TDM-1. Patients with stable brain metastasis are eligible. Margetuximab is a Fc modified monoclonal antibody. End goal--to see if better results than of herceptin. 

Biosimilars/biologics - drugs that are like natural substances in our bodies. Myl-1410O, similar to Herceptin, not FDA approved yet. Dec 2016--Journal of the American Medical  Association (JAMA) publishes Phase 3 data by Mylan N.V. and Biocon LTD of efficacy of biosimilar Herceptin (Trastuzumab).

click here Medivizor Website updated Nov 2015 --"The mTOR protein is a molecule normally responsible for cell growth, division and survival. Drugs that inhibit the actions of mTOR have been the focus of recent cancer treatment research. Various mTOR inhibitors, such as everolimus (Afinitor), temsirolimus (Torisel) and sirolimus (Rapamune) are currently being investigated in clinical trials including breast cancer patients."
"Research into the use of mTOR inhibitors for the treatment of HER2-positive breast cancer patients is still in early phases. A phase one trial investigating the combination of everolimus and trastuzumab demonstrated that the combination is well tolerated and safe to use. Preliminary results from a phase II trial among recurrent breast cancer patients reported that everolimus in combination with trastuzumab and chemotherapy resulted in a stable disease (no additional growth of the cancer for 6 months) in up to 62% of patients. A large, controlled, phase III trial investigating everolimus as first choice treatment for HER2-positve breast cancer patients is currently underway."

Neratinib + Temsirolimusd (Neratinib-may cause severe diarrhea)

A Phase I/II Trial of Temsirolimus Plus Neratinib for Patients With Metastatic HER2-Amplified or Triple Negative Breast Cancer www.clinicaltrials.gov Began April 2015, Ends Dec 2015
The phase III ExteNET trial evaluated neratinib, an oral tyrosine kinase inhibitor that blocks HER2, in patients with HER2-positive breast cancer. The 2-year invasive disease-free survival rate was 93.9% in the neratinib arm versus 91.6% with placebo, representing a 33% reduction in the risk of recurrence (HR = 0.67; P = .009). However, 95.4% of patients treated with neratinib experienced all-grade diarrhea (39.9% were grade 3/4), points out Rugo.

The rates of diarrhea seen in the ExteNET study could be related to an initial lack of antidiarrheal therapy, which caused immediate diarrhea in the majority of patients. The management of diarrhea is now better understood, and the current standard includes routine prophylaxis, says Rugo. Studies continue to assess neratininb, and there is interest in combining neratinib with trastuzumab and pertuzumab, adds Rugo.

From http://www.onclive.com Phase III ExteNET trial - looked at Neratinib (an oral tyrosine kinase inhibitor that blocks EGFRs, and HER2 + HER4) showed a 33% reduction in risk of invasive Her 2 neu positive breast cancer after early stage treatment. Diarrhea was problimatic.  

For issues with diarrhea from Neratinib called PB272, see here 

Nerlynx (Puma Biotechnology) also known as Neratinib, FDA approved June 2017 for early stage treatment after Herceptin. Targets proteins that promote cell growth: EGFRs, HER2 and HER4.

Phase 3 trials--MM302 - similar to Kadcyla in method of delivery- I learned from Sarah Merchant's blog that the main ingredient is adriamycin.

Some of the drugs used to treat breast cancer are also used to treat other cancers.
