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.

Background: Breast Cancer (BC) is a heterogeneous disease comprising distinct subtypes defined at present by tumor molecular markers. Over the past decades, more effective treatments targeted to specific markers have been developed and tested in clinical trials. While clinical trials have demonstrated the impact of these targeted treatments on recurrence and mortality rates, little is known about survival patterns associated with specific subtypes in the general population. We examined overall survival outcomes according to tumor subtype and stage in a diverse, population-based cohort of BC patients (pts) in California. Methods: Through the California (CA) Cancer Registry, we identified all female CA residents diagnosed with primary invasive BC between 1/1/2005 and 12/31/2011. We classified these cancers as early breast cancer (EBC, stages I-III) vs. de novo metastatic (MBC, stage IV). We further grouped these cancers into 4 subtypes based on HER2 and hormone receptor (HR) status. For a subset of women with available survival data, we calculated the proportion surviving at 3 years (yrs), and median overall survival using the Kaplan-Meier method. Results: 118,817 EBC pts (61.4% HR+/HER2-, 9.9% HR+/HER2+, 13.3% unclassified, 4.9% HR-/HER2+, and 10.6% triple-negative (TN)) and 6,268 MBC pts (43.7% HR+/HER2-, 13.0% HR+/HER2+, 23.3% unclassified, 8.9% HR-/HER2+, and 10.7% TN) were identified. Table 1 presents survival time in EBC vs. MBC, and for each of the receptor subtypes of BC. For EBC, 3-yr survival rate was highest (95.1%) for HR+/HER2- pts and shortest (84.3%) for TN. For the HER2- and HER2+ overall groups (regardless of HR status), 3-yr survival was similar (93.3% vs. 92.5%, respectively). The longest survival for de novo MBC was observed for the HR+/HER2+ subtype (median OS: 45.3 months (mos)), compared to 38.7 mos for the HR+/HER2- subtype, 23.1 mos for the HR-/HER2+ subtype and 12.7 mos for the TN subtype. For the overall HER2+ and HER2- subtypes, HER2+ MBC had slightly better survival (3-yr rate: 47.6% and median OS: 33.6 mos) than HER2- MBC pts (3-yr rate: 44.8% and median OS: 30.9 mos). Conclusions: This study demonstrates the relevance of subtype on the OS of BC pts in a large population of CA women. Although HER2+ status is a negative prognostic factor, survival was similar between HER2+ and HER2- pts, likely due to available treatments targeting HER2. TNBC pts had the shortest survival, especially when they presented with metastatic disease. There remains an urgent unmet need for more effective treatments for TNBC. Table 1.

Introduction The Systemic Therapies for HER2-Positive Metastatic Breast Cancer Registry (SystHERs) is a US-based prospective observational cohort study currently enrolling patients with HER2-positive metastatic breast cancer (MBC). It began in 2012 and aims to provide real-world insight into the disease course, treatment patterns and associated clinical outcomes, and patient-reported experiences of disease. Here we describe the baseline characteristics of this population to date, including the proportion of patients with de novo and recurrent HER2-positive MBC. Methods SystHERs aims to enroll ∼1000 patients with HER2-positive MBC within 6 months of first metastatic diagnosis. At enrollment, investigators report whether patients have recurrent or de novo MBC, the latter defined as distant metastases at the time of initial MBC diagnosis. Results As of February 17, 2014, data are available from 306 of 319 enrolled patients. Forty-six percent (142/306) had de novo HER2-positive MBC. For the 54% (164/306) with recurrent HER2-positive MBC, median disease-free interval (DFI, defined here as time from early-stage breast cancer diagnosis to diagnosis of MBC) was 43.6 (range 0.5–270.2) months. For these patients with recurrent disease, 54% (89/164) received (neo)adjuvant HER2-targeted therapy. Baseline patient and tumor characteristics are shown below.

The DFI for patients with recurrent HER2-positive MBC also appears to be longer (median DFI 43.6 months in SystHERs vs. 32.6 months in registHER). We hypothesize that the proportion of patients with de novo MBC within the metastatic population is higher due to the use of advanced screening techniques which allow better detection of metastases, and due to a reduction in recurrences related to the availability of HER2-targeted adjuvant therapy. Changes in the population characteristics of patients with HER2-positive MBC may impact treatment strategies and have trial design implications. Updated data from approximately 500 patients are expected by the time of presentation.

Purpose Detection 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. Methods MyPathway ( 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-pathway cohort. Results Between April 1, 2014 and November 1, 2016, 251 patients with 35 different tumor types received study treatment. The efficacy population contains 230 treated patients who were evaluated for response or discontinued treatment before evaluation. Fifty-two patients (23%) with 14 different tumor types had objective responses (complete, n = 4; partial, n = 48). Tumor-pathway cohorts with notable objective response rates included human epidermal growth factor receptor-2–amplified/overexpressing colorectal (38% [14 of 37]; 95% CI, 23% to 55%) and v-raf murine sarcoma viral oncogene homolog B1 V600-mutated non–small-cell lung cancer (43% [six of 14]; 95% CI, 18% to 71%). Conclusion 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.

Purpose Patient registries are used to monitor safety, examine real-world effectiveness, and may potentially contribute to comparative effectiveness research. To our knowledge, life sciences industry (LSI)-sponsored registries have not been systematically categorized. This study represents a first step toward understanding such registries over time. Methods Studies described as registries were identified in the ClinicalTrials.gov database. Characteristics from these registry records were abstracted and analyzed. Results Of 1202 registries identified, approximately 47% reported LSI sponsorship. These 562 LSI registries varied in focus: medical devices (n = 193, 34%), specific drugs (n = 173, 31%), procedures (n = 29, 5%), or particular diseases (n = 139, 25%). Thirty-three registries (

Background Human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer (MBC) is an aggressive form of breast cancer and is historically associated with poor outcomes compared with HER2-negative MBC. Since 1998, four drugs have been globally approved for the targeted treatment of HER2-positive MBC. Additional advances in patient care—such as improved breast cancer screening, HER2 testing, and supportive care—have also occurred. The objective of this systematic review and meta-analysis is to determine whether there has been a cumulative change in survival over time in patients with HER2-positive advanced breast cancer based on results from interventional clinical trials (ICTs) and observational studies and to compare outcomes across these types of studies. Methods/Design A systematic search of Medline, EMBASE, and the Cochrane Central Register of Controlled Trials will be performed. Two investigators will independently assess each abstract for inclusion. English language reports of ICTs and observational studies that include patients with HER2-positive advanced breast cancer from 1987 onwards will be considered. The primary outcome of interest is overall survival; secondary outcomes include progression-free survival and safety. Data on clinical outcomes, as well as on study design, study population, treatment/intervention, methodological quality, and outcomes, will be extracted using a structured codebook developed by the authors for this study. Standard and cumulative random effects meta-analysis will be performed to derive pooled risk estimates, both overall and by study design, controlling for covariates such as aggregate demographic and clinical characteristics of patients, treatment/intervention, and study characteristics. Heterogeneity of studies will be evaluated using the I2 statistic. Differences in risk estimates by quality characteristics will be performed using meta-regression. Discussion This study will evaluate current and evolving trends in survival associated with HER2-positive advanced breast cancer over nearly 30 years and will build upon prior, less comprehensive, systematic analyses. This information is important to patients, healthcare providers, and researchers, particularly in the advanced disease setting, in which new therapies have been recently approved. Including observational studies allows us to evaluate real-world effectiveness; useful information will be gained by comparing findings from observational studies with those from ICTs.

9073 Background: Treatments targeting critical molecular alterations (EGFR, ALK, and ROS1) in NSCLC are highly effective. MyPathway (NCT02091141) is an ongoing, phase 2, multi-basket study evaluating the efficacy of targeted treatment in non-indicated tumor types harboring alterations in the HER2, BRAF, Hedgehog (Hh), or EGFR pathways. Interim results in NSCLC are presented. Methods: Patients with previously treated advanced NSCLC and alterations in the HER2 (amplification and/or mutation), BRAF (V600E or other mutations), Hh (SMO or PTCH-1 mutations), or EGFR (mutations other than known activating mutations) pathways received standard doses of pertuzumab + trastuzumab, vemurafenib, vismodegib, or erlotinib, respectively, until disease progression or unacceptable toxicity. The HER2, BRAF, and Hh cohorts are included in this analysis. The primary endpoint is investigator-assessed objective response rate (ORR, defined as complete response [CR] + partial response [PR]) by RECIST v1.1. Results: As of November 30, 2016, 61 patients with NSCLC and HER2 (n = 36), BRAF (n = 22), or Hh (n = 3) alterations have been treated (median age of 64 years, 49% male, 85% adenocarcinoma, and a median of 2 previous regimens). Median treatment duration was 1.8 (range, 0–21.4) months. Efficacy in the 55 patients with the minimum required follow-up for efficacy analysis is summarized in the table. Conclusions: Targeted therapy is active in patients with previously treated NSCLC harboring BRAF V600E mutations or HER2 alterations (amplifications and/or mutations). These cohorts have been expanded as MyPathway accrual continues. Additional efficacy data and details regarding molecular alterations will be presented. Clinical trial information: NCT02091141.

Background Amplification of the human epidermal growth factor receptor 2 (HER2) gene occurs in approximately 20% of invasive breast cancer cases and is associated with a more aggressive disease course than HER2-negative breast cancer. HER2-targeted therapies have altered the natural history of HER2-positive breast cancer, a trend that will likely further improve with the recent approval of new agents. A prospective, observational cohort study was designed and initiated to provide real-world insights into current treatment patterns, long-term survival, and patients’ experiences with initial and subsequent treatments for HER2-positive metastatic breast cancer (MBC). Methods/Design The Systematic Therapies for HER2-positive Metastatic Breast Cancer Study (SystHERs) is a US-based prospective observational cohort study enrolling patients ≥18 years of age with recently diagnosed HER2-positive MBC not previously treated with systemic therapy in the metastatic setting. The primary objective of the study is to identify treatment patterns and clinical outcomes in recently diagnosed patients in a variety of practice settings. Secondary objectives include comparative efficacy, safety, and patient-reported outcomes (PROs). Healthcare resource utilization is an exploratory end point. Tumor tissue and blood sample collection is optional. The SystHERs registry will enroll approximately 1000 patients over a 3-year period, after which the study will continue for ≥5 years, allowing for a maximum follow-up of 8 years. The treating physician will determine all care and the frequency of visits. PRO measures will be completed at study enrollment and every 90 days. Clinical data will be abstracted quarterly from patient records. The first patient was enrolled in June 2012, and preliminary descriptive data based on 25% to 30% of the final study population are expected at the end of 2013, and as of April 25, 2014, 386 patients are enrolled. Discussion SystHERs is expected to provide in-depth data on demographic, clinicopathological, and treatment patterns and their associations with clinical outcomes, PROs, and healthcare resource utilization. Tumor tissue and DNA repositories will also be established for use in future translational research. Trial registration number NCT01615068 (ClinicalTrials.gov identifier).

348 Background: Patients (pts) with mUC have few treatment options beyond the second-line setting. HER2 gene amplification has been reported in a minority of pts with UC, but there have been anecdotal reports of the activity of HER2-targeted agents. MyPathway is a multi-basket study evaluating the efficacy and safety of targeted therapies in non-indicated tumor types harboring relevant molecular alterations. We present preliminary data for pts with HER2-positive mUC receiving HER2-targeted treatment with pertuzumab + trastuzumab. Methods: MyPathway (NCT02091141) is an open-label, multicenter, phase IIA study. Pts in this subset analysis had refractory mUC with HER2 amplification or putative activating mutations by gene sequencing, FISH, or IHC. Pts received standard doses of pertuzumab + trastuzumab without chemotherapy until disease progression or unacceptable toxicity. The primary endpoint is investigator-assessed overall response rate (RECIST v1.1). Results: As of July 31, 2016, 12 pts with platinum-resistant HER2-positive mUC (HER2-amplified, n=9; HER2-mutated, n=3) have been enrolled. At a median follow-up of 5.4 (range 0.9–14.5) mos, 1 pt had complete response (CR, ongoing at 12.5 mos), 2 had partial responses (PR; duration of response, 3.7 and 5.5 mos), and 2 had stable disease (SD) for >4 mos (Table). Safety was consistent with the product labels. Conclusions: Preliminary results indicate that the combination of pertuzumab + trastuzumab has activity in previously treated HER2-amplified mUC, including a durable CR in a pt with peritoneal metastases. Accrual to MyPathway is ongoing. Clinical trial information: NCT02091141. [Table: see text]

402 Background: Biliary cancers have a high mortality rate, with limited treatment options. While HER2 is overexpressed in 9-20% of biliary cancers, it has not been fully explored as a therapeutic target. MyPathway is a multi-basket study evaluating the efficacy and safety of targeted therapies in non-indicated tumor types harboring relevant genetic alterations. We present preliminary data for patients with HER2-positive metastatic biliary cancer receiving HER2-targeted treatment with pertuzumab + trastuzumab. Methods: MyPathway (NCT02091141) is an open-label, multicenter, phase IIA study. Patients in this subset analysis had refractory metastatic biliary cancer with HER2 amplification/overexpression or putative activating mutations by gene sequencing, FISH, or IHC. Patients received standard doses of pertuzumab + trastuzumab until disease progression or unacceptable toxicity. The primary endpoint is investigator-assessed overall response rate (RECIST v1.1). Results: As of July 31, 2016, 11 patients with HER2-positive biliary cancer (HER2-amplified/overexpressed, n = 8; HER2-mutated, n = 3 [D277Y, S310F, and A775-G776insYVMA]) have been enrolled. At a median follow-up of 4.2 (range 2.0–12.0) months, 4 patients had partial responses (PR) and 3 had stable disease (SD) for > 4 months (Table). Safety was consistent with the package inserts. Conclusions: Preliminary results indicate that pertuzumab + trastuzumab has activity in HER2 amplified/overexpressed/mutated metastatic biliary tumors, suggesting HER2 as a therapeutic target for these rare cancers. Accrual to MyPathway is ongoing. Clinical trial information: NCT02091141. [Table: see text]

676 Background: Among recent advances in precision medicine, HER2 has emerged as a potential therapeutic target for advanced colon cancer. MyPathway is a multi-basket study evaluating the efficacy and safety of targeted therapies in non-indicated tumor types harboring relevant genetic alterations. We present updated data for an expanded cohort of patients with HER2-amplified/overexpressed mCRC receiving HER2-targeted therapy with pertuzumab + trastuzumab. Methods: MyPathway (NCT02091141) is a multicenter, open-label, phase IIA study. Patients in this analysis had treatment-refractory HER2-amplified/overexpressed mCRC by gene sequencing, FISH, or IHC. Patients received standard doses of pertuzumab + trastuzumab until disease progression or unacceptable toxicity. The primary endpoint is investigator-assessed overall response rate. The cutoff date was July 31, 2016. Results: Of 34 patients with mCRC enrolled, 32 have had ≥1 tumor assessment. At a median follow-up of 5.2 (range 0.7–18.3) months from treatment initiation, 12 patients had partial responses (PR), with stable disease (SD) for >4 months in 3 additional patients (Table). The safety profiles were consistent with the product labels. Conclusions: Interim data show that HER2-targeted therapy with pertuzumab + trastuzumab, a chemotherapy-free regimen, is active in heavily pretreated HER2-amplified/overexpressed mCRC. The ORR was 37.5%, responses were durable (median 11.1 months), and the CBR was 46.9%. Accrual to MyPathway is ongoing. Clinical trial information: NCT02091141. [Table: see text]

LBA11511 Background: The MyPathway study (NCT02091141) evaluates agents targeting the HER2, BRAF, Hedgehog (Hh), or EGFR pathways in non-indicated tumors with relevant genetic abnormalities. Early results from MyPathway merit pre-planned tumor-cohort expansion. Methods: Eligible pts had advanced solid tumors with no curative therapy and molecular alterations in HER2, BRAF, Hh, or EGFR. Pts received standard doses of trastuzumab + pertuzumab (for the HER2 pathway), vemurafenib (BRAF), vismodegib (Hh), or erlotinib (EGFR) based on alteration. The primary endpoint is investigator-evaluated response rate within a tumor-pathway cohort (RECIST 1.1). Cohort size and expansion is determined by Simon’s two-stage design criteria. Results: By December 14, 2015, MyPathway included 129 pts with available baseline assessments and alterations in HER2 (n = 82; 53 amplifications, 23 mutations, 5 both, 1 RBMS-NRG1 fusion), BRAF (n = 33; 18 V600E, 15 other), Hh (n = 8; 7 PTCH1, 1 SMO), or EGFR (n = 6). Pts had a median of 3 (range, 0–10) prior lines of therapy. Best responses (n = 118) are shown below; 11 pts had insufficient follow-up for reevaluation and were not analyzed. 22 pts had PR/CR (1 CR); current response durations were up to 11 months. Conclusions: Targeted therapy produced responses in pts with 9 different tumor types outside of current drug indications. As enrollment increases for all tumor-pathway cohorts, analyses of tumor responses based on specific alterations (eg, HER2 amplifications vs. mutations) are planned. The HER2 amplified colorectal, bladder, and biliary, and the BRAF lung cohorts will be expanded based on observed activity. Clinical trial information: NCT02091141. [Table: see text]

The considerable uncertainty regarding cancer risks associated with inherited mutations of BRCA2 is due to unknown factors.1 To investigate whether common genetic variants modify penetrance for BRCA2 mutation carriers, we undertook a two-staged genome-wide association study in BRCA2 mutation carriers. In stage 1 using the Affymetrix 6.0 platform, 592,163 filtered SNPs genotyped were available on 899 young (, National Breast Cancer Foundation (U.S.), Starr Cancer Consortium, National Institutes of Health (U.S.) (NCI: P20CA103694-3 ), Lymphoma Foundation
