TL;DR: In oestrogen receptor-positive, HER2-negative, lymph node-negative patients, multianalyte tests such as urokinase plasminogen activator (uPA)-PAI-1, Oncotype DX, MammaPrint, EndoPredict, Breast Cancer Index (BCI) and Prosigna (PAM50) may be used to predict outcome and aid adjunct therapy decision-making.

TL;DR: Pertuzumab, a recombinant humanized IgG1 MAb, is the first of a new class of agents known as HER dimerization inhibitors, and may be an effective anticancer strategy in tumors with either normal or elevated expression of HER2.
Abstract: Dimerization is essential for activity of human epidermal growth factor receptors (HER1/EGFR, HER2/ErbB2, HER3/ErbB3, and ErbB4) and mediates intracellular signaling events leading to cancer cell proliferation, survival, and resistance to therapy. HER2 is the preferred dimerization partner. Activation of HER signaling pathways may be blocked by inhibition of dimer formation using a monoclonal antibody (MAb) directed against the dimerization domain of HER2. The murine MAb 2C4 that specifically binds the HER2 dimerization domain was cloned as a chimeric antibody, humanized using a computer-generated model to guide framework substitutions, and variants were tested as Fabs. Pharmacokinetics and toxicology were evaluated in rodents and cynomolgus monkeys. Cloning the variable domains of MAb 2C4 into a vector containing human kappa and CH1 domains allowed construction of a mouse-human chimeric Fab. DNA sequencing of the chimeric clone permitted identification of CDR residues. The full-length IgG1 of variant F-10 was equivalent in binding to chimeric IgG1 and was designated pertuzumab (rhuMAb 2C4; Omnitarg). Pertuzumab pharmacokinetics was best described by a two-compartment model with a distribution phase of <1 day, terminal half-life of ~10 days, and volume of distribution of ~40 mL/kg that approximates serum volume. With the exception of diarrhea, pertuzumab was generally well tolerated in cynomolgus monkeys. Pertuzumab, a recombinant humanized IgG1 MAb, is the first of a new class of agents known as HER dimerization inhibitors. Inhibition of HER dimerization may be an effective anticancer strategy in tumors with either normal or elevated expression of HER2.

TL;DR: The four currently approved targeted therapy regimens in the MyPathway study produced meaningful responses when administered without chemotherapy in several refractory solid tumor types not currently labeled for these agents.
Abstract: PurposeDetection of specific molecular alterations in tumors guides the selection of effective targeted treatment of patients with several types of cancer. These molecular alterations may occur in other tumor types for which the efficacy of targeted therapy remains unclear. The MyPathway study evaluates the efficacy and safety of selected targeted therapies in tumor types that harbor relevant genetic alterations but are outside of current labeling for these treatments.MethodsMyPathway (ClinicalTrials.gov identifier: NCT02091141) is a multicenter, nonrandomized, phase IIa multiple basket study. Patients with advanced refractory solid tumors harboring molecular alterations in human epidermal growth factor receptor-2, epidermal growth factor receptor, v-raf murine sarcoma viral oncogene homolog B1, or the Hedgehog pathway are treated with pertuzumab plus trastuzumab, erlotinib, vemurafenib, or vismodegib, respectively. The primary end point is investigator-assessed objective response rate within each tumor-p...

TL;DR: Her2-targeted therapy is recommended for patients with HER2-positive advanced breast cancer, except for those with clinical congestive heart failure or significantly compromised left ventricular ejection fraction, who should be evaluated on a case-by-case basis.
Abstract: Purpose To provide evidence-based recommendations to practicing oncologists and others on systemic therapy for patients with human epidermal growth factor receptor 2 (HER2) –positive advanced breast cancer. Methods The American Society of Clinical Oncology convened a panel of medical oncology, radiation oncology, guideline implementation, and advocacy experts and conducted a systematic literature review from January 2009 to October 2012. Outcomes of interest included overall survival, progression-free survival (PFS), and adverse events. Results A total of 16 trials met the systematic review criteria. The CLEOPATRA trial found survival and PFS benefits for docetaxel, trastuzumab, and pertuzumab in first-line treatment, and the EMILIA trial found survival and PFS benefits for trastuzumab emtansine (T-DM1) in second-line treatment. T-DM1 also showed a third-line PFS benefit. One trial reported on duration of HER2-targeted therapy, and three others reported on endocrine therapy for patients with HER-positive ...

TL;DR: Dual HER2-targeted therapy with pertuzumab plus trastuzumAB is well tolerated and could represent a therapeutic opportunity for patients with heavily pretreated, Her2-amplified metastatic colorectal cancer.
Abstract: Summary Background Therapies targeting HER2 have improved clinical outcomes in HER2-positive breast and gastric cancers, and are emerging as potential treatments for HER2-positive metastatic colorectal cancer. MyPathway evaluates the activity of targeted therapies in non-indicated tumour types with potentially predictive molecular alterations. We aimed to assess the activity of pertuzumab and trastuzumab in patients with HER2-amplified metastatic colorectal cancer. Methods MyPathway is an ongoing, phase 2a, multiple basket study. Patients in this subset analysis were aged 18 years or older and had treatment-refractory, histologically confirmed HER2-amplified metastatic colorectal cancer with measurable or evaluable disease and an Eastern Cooperative Oncology Group performance status score of 2 or less, enrolled from 25 hospitals or clinics in 16 states of the USA. Patients received pertuzumab (840 mg loading dose, then 420 mg every 3 weeks, intravenously) and trastuzumab (8 mg/kg loading dose, then 6 mg/kg every 3 weeks, intravenously). The primary endpoint was the proportion of patients who achieved an objective response based on investigator-reported tumour responses. Analyses were done per protocol. This ongoing trial is registered with ClinicalTrials.gov , number NCT02091141 . Findings Between Oct 20, 2014, and June 22, 2017, 57 patients with HER2-amplified metastatic colorectal cancer were enrolled in the MyPathway study and deemed eligible for inclusionin this cohort analysis. Among these 57 evaluable patients, as of Aug 1, 2017, one (2%) patient had a complete response and 17 (30%) had partial responses; thus overall 18 of 57 patients achieved an objective response (32%, 95% CI 20–45). The most common treatment-emergent adverse events were diarrhoea (19 [33%] of 57 patients), fatigue (18 [32%] patients), and nausea (17 [30%] patients). Grade 3–4 treatment-emergent adverse events were recorded in 21 (37%) of 57 patients, most commonly hypokalaemia and abdominal pain (each three [5%] patients). Serious treatment-emergent adverse events were reported in ten (18%) patients and two (4%) of these adverse events (ie, chills and infusion-related reaction) were considered treatment related. There were no treatment-related deaths. Interpretation Dual HER2-targeted therapy with pertuzumab plus trastuzumab is well tolerated and could represent a therapeutic opportunity for patients with heavily pretreated, HER2-amplified metastatic colorectal cancer. Funding F Hoffmann-La Roche/Genentech.
