Many newer treatments for metastatic breast cancer are under study and prognosis is improving. Some of these have entered the clinics while others are in study phase. We will describe some of the newest drugs available to us in breast cancer now a days.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Cyclin-dependent kinase 4 and 6 (CDK4\/6) inhibitors<\/h2>\n\n\n\n<p>CDK4 and CDK6 are\u00a0<a href=\"javascript:SpotLight('iframe','Popup\/Enzyme.htm',325,160);\">enzymes<\/a>\u00a0important in cell division. They have been designed to inhibit various checkpoints in cell cycle leding to cell cycle arrest and cell death. Abemaciclib, palbociclib and\u00a0ribociclib are FDA-approved CDK4\/6 inhibitors for breast cancer treatment. These have changed the landscape of <a href=\"javascript:SpotLight('iframe','Popup\/HormoneReceptorStatus.htm',325,160);\">hormone receptor-positive<\/a>,\u00a0<a href=\"javascript:SpotLight('iframe','Popup\/HER2.htm',325,230);\">HER2-negative<\/a>\u00a0metastatic breast cancers. These drugs are used in combination with hormone treatment in the abovesaid indication.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">HER2-targeted therapies<\/h2>\n\n\n\n<p>About 15-20 percent of breast cancers overexpress HER2 neu. The overexpression of HER2 neu stimulates the downstream pathways leading to cell growth. Trastuzumab was the only anti HER 2 neu monoclonal antibody available earlier. Lately, pertuzumab has shown encouraging results when added to trastuzumab and hence it is now recommend to use the combination of two drugs along with chemotherapy rather trastuzumab alone. The combination gives sustained and deeper response. Other HER2-targeted antibody drugs, such as margetuximab, are under study.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">HER2 antibody-drug conjugates<\/h2>\n\n\n\n<p>These are highly potent biological drugs built by attaching an anticancer drug to an antibody against Her 2 neu, with either a permanent or a labile linker. The antibody specifically targets Her 2 neu receptor found on breast cancer cells. Once it binds to the cell, it triggers internalization of the antibody, together with the drug. This delivers drugs with a very high specificity to the diseased cells, maximizing their efficacy and minimizing systemic exposure. Earlier the only drug available in this class was T- DM 1 which contains anti microtubule inhibitor DM1. Lately more potent drug trastuzumab deruxtecan is now available. It exhibits potent and durable responses even in heavily pretreated Her2 neu breast cancer population. Other beauty of this drug is to exhibit responses in low Her2 disease the trials for which are underway.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Tyrosine kinase inhibitors<\/h2>\n\n\n\n<p>Kinases are proteins in cells that normally relay growth signals. Drugs that block kinases are called tyrosine kinase receptor inhibitor (TKI). They inhibit the tyrosine receptor kinase domain of her 2 neu receptor and inhibit the downstream signaling pathway. The only TKI available earlier was lapatinib with fewer response rates. Now we have two more oral TKI neratinib and tucatinib out of which tucatnib needs special mention. Tucatinib has very high systemic responses in heavily pretreated her2 neu breast cancer population. Apart from that it also exhibits excellent responses in controlling CNS metastasis which is often problematic and frustrating while treating her2 neu breast cancer population. \u00a0<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">PI3 kinase inhibitors<\/h2>\n\n\n\n<p><strong>Phosphoinositide 3-kinase inhibitor<\/strong>&nbsp;(<strong>PI3K inhibitor<\/strong>) functions by inhibiting <a href=\"https:\/\/en.wikipedia.org\/wiki\/Phosphoinositide_3-kinase\">phosphoinositide 3-kinase<\/a>&nbsp;enzyme, which is a part of the&nbsp;<a href=\"https:\/\/en.wikipedia.org\/wiki\/PI3K\/AKT\/mTOR_pathway\">PI3K\/AKT\/mTOR pathway<\/a>. This is an important signalling pathway for many cellular functions such as growth control, metabolism and&nbsp;<a href=\"https:\/\/en.wikipedia.org\/wiki\/Translation_(biology)\">translation<\/a>&nbsp;<a href=\"https:\/\/en.wikipedia.org\/wiki\/Initiation_factor\">initiation<\/a>. These drugs inhibit this pathway to induce tumor suppression.<\/p>\n\n\n\n<p>The PI3 kinase inhibitor&nbsp;<a href=\"https:\/\/ww5.komen.org\/BreastCancer\/RecommendedTreatmentsforMetastaticBreastCancer.html#PI3\">alpelisib<\/a>&nbsp;is FDA-approved to treat metastatic hormone receptor-positive and HER2-negative breast cancers harboring a mutation in the&nbsp;<em>PIK3CA<\/em>&nbsp;gene.<\/p>\n\n\n\n<p>Other similar class of drug which awaits FDA approval is capivasertib which has shown promising results in combination with fulvestrant in hormone receptor positive her2 negative and in combination with paclitaxel in triple negative breast cancer.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">PARP inhibitors<\/h2>\n\n\n\n<p><a href=\"https:\/\/en.wikipedia.org\/wiki\/Poly_ADP_ribose_polymerase\">Poly ADP ribose polymerase<\/a> (PARP) is an enzyme involved in DNA repair. PARP inhibitors are only used in breast cancer treatment for people who have a&nbsp;<a href=\"https:\/\/ww5.komen.org\/BreastCancer\/BRCA1andBRCA2.html\"><em>BRCA1<\/em>&nbsp;or&nbsp;<em>BRCA2<\/em>&nbsp;gene mutation<\/a>.&nbsp;<em>BRCA1\/2<\/em>-related breast cancers seem to be sensitive to DNA damage involving the PARP enzyme.<\/p>\n\n\n\n<p>The PARP inhibitors&nbsp;<a href=\"https:\/\/ww5.komen.org\/BreastCancer\/RecommendedTreatmentsforMetastaticBreastCancer.html#PARP\">olaparib (Lynparza)<\/a>&nbsp;and&nbsp;<a href=\"https:\/\/ww5.komen.org\/BreastCancer\/RecommendedTreatmentsforMetastaticBreastCancer.html#PARP\">talazoparib (Talzenna)<\/a>&nbsp;are FDA-approved for the treatment of HER2-negative metastatic breast cancer in people who have a&nbsp;<em>BRCA1\/2<\/em>&nbsp;gene mutation.<\/p>\n\n\n\n<p>Other PARP inhibitors are under study for use in metastatic breast cancer treatment.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Immunotherapy<\/h2>\n\n\n\n<p>Drugs that help the body\u2019s immune system attack cancer cells are used to treat many cancers (including melanoma, lung cancer, bladder cancer and kidney cancer).<\/p>\n\n\n\n<p>Immunotherapy drugs (including vaccines) for breast cancer haven&#8217;t shown results as strong as have been seen for other cancers. However, they may be effective in treating some breast cancers.<\/p>\n\n\n\n<p>Researchers are studying how to identify the best biomarkers for immunotherapy.<\/p>\n\n\n\n<p>\u201cCheckpoint inhibitors\u201d are the most widely used type of immunotherapy drugs. These drugs \u201ctake the brakes off\u201d the natural factors that limit how the immune system can control tumor cells.<\/p>\n\n\n\n<p>The checkpoint inhibitor immunotherapy drug&nbsp;<a href=\"https:\/\/ww5.komen.org\/BreastCancer\/RecommendedTreatmentsforMetastaticBreastCancer.html#atezolizumab\">atezolizumab (Tecentriq)<\/a>&nbsp;is FDA-approved for the treatment of metastatic&nbsp;<a href=\"https:\/\/ww5.komen.org\/BreastCancer\/TripleNegativeBreastCancer.html\">triple negative<\/a>&nbsp;breast cancer that express (have a lot of) programmed cell death protein 1 (PD-L1).<\/p>\n\n\n\n<p>The checkpoint inhibitor&nbsp;<a href=\"https:\/\/ww5.komen.org\/BreastCancer\/RecommendedTreatmentsforMetastaticBreastCancer.html#pembrolizumab\">pembrolizumab (Keytruda)<\/a>&nbsp;is FDA-approved to treat metastatic breast cancers that have a high tumor mutational burden [<a href=\"https:\/\/ww5.komen.org\/BreastCancer\/MetastaticBreastCancerReferences.html\">101<\/a>].

Antibody-drug conjugates are a combination of an antibody therapy and a chemotherapy drug. Combining these into one drug allows the targeted delivery of the chemotherapy to specific cancer cells.<\/p>\n\n\n\n<p>Some breast cancers have cells with higher levels of the protein Trop-2 than other breast cancers (they express Trop-2).
