TPS596 Background: WSG (West German Study Group)-ADAPTcycle is a prospective, multi-center, interventional, two-arm, open-label, controlled (neo)adjuvant, non-blinded, randomized phase III trial (EudraCT 2018-003749-40). It investigates whether HR+/HER2- intermediate-risk patients (pts) (about 20 % of HR+/HER2- early breast cancer, EBC) identified during screening (OncotypeDX and 3-week endocrine therapy (ET)) derive additional benefit from 2-years of the CDK4/6 inhibitor ribociclib plus ET compared to chemotherapy (CT) (followed by adjuvant ET). Co-primary endpoints are disease-free and distant disease-free survival. Methods: Starting Q1 2019 (enrollment 36 months, 80 sites), 5600 pts will be screened and 1670 randomized in a 3:2 ratio (1002 to ribociclib + ET; 668 to standard CT followed by ET). Pre-/postmenopausal pts with histologically confirmed invasive HR+/HER2- EBC at clinically enhanced risk (cT2-4 or Ki67 > 20 % or G3 or cN+) are eligible if they fulfill the ADAPT intermediate-risk group criteria: Recurrence Score (RS) ≤ 25 and poor endocrine response or RS > 25 and good endocrine response in p/cN0-1 pts or RS ≤ 25 with good endocrine response in c/pN2-3 pts. Endocrine responsiveness is determined by Ki67 response (drop to ≤ 10 %) after 3-week ET. Treatment duration is 2 years for the ribociclib + ET (premenopausal: AI + GnRH) arm and 16-24 weeks for the CT arm; treatment can be given in the neoadjuvant or adjuvant setting. 5-year follow-up consists of standard adjuvant ET. Patient reported outcomes (ePROs) are collected using CANKADO; ECG monitoring is performed using a novel CANKADO-based methodology. For translational analyses, tumor tissue will be collected at baseline (prior to ET), after 3-weeks ET (+/- 1w). Additional samples are required if residual tumor is diagnosed in case of neoadjuvant treatment and at time of recurrence. Exploratory tissue biomarker research will be conducted to assess alterations of molecular markers (e. g., ESR1, PIK3CA, CCND1, CDKN2A, RB1). Circulating DNA and tumor cells from blood samples will be used to assess mutations, gene expression, etc. Clinical trial information: 2018-003749-40.

TPS599 Background: In-vitro and in-vivo evidence suggest that aspirin may have an anti-tumor effect. Multiple epidemiologic studies have reported improved breast cancer survival among regular aspirin users compared to non-users. Pooled data from randomized trials of aspirin for cardiovascular disease have also reported a decreased risk of metastatic cancer among aspirin users. However, the exact benefits and risks for breast cancer survivors need to be confirmed in a randomized controlled trial. Even if the clinical effect were modest, the global impact would be substantial since aspirin is inexpensive and widely available. Methods: The primary objective is to compare the effect of 300 mg daily aspirin versus placebo upon invasive disease-free survival (iDFS) in high risk HER2 negative breast cancer patients. Secondary objectives include effects on overall survival, cardiovascular disease, toxicity, and adherence. A biospecimen repository will be created for correlative analyses including tumor collection at baseline and blood and urine samples and questionnaires assessing lifestyle factors associated with inflammation (pain, sleep, stress, and depression) at baseline and 2 years. Study design: Subjects will be randomized (1:1) to aspirin 300 mg vs placebo daily for 5 years in a double-blinded fashion. Stratification factors include hormone receptor (HR) status (positive vs negative), body mass index ( < or ≥ 30 kg/m2), and stage (II vs III). Subjects will be followed every 6 six months while on study drug, then annually for 10 years. Accrual goal is 2936 patients to reach 381 iDFS events. We have 80% power to detect HR 0.75 assuming 5-year iDFS on placebo of 77%. Eligibility: Eligible subjects include patients aged 18-70 diagnosed with a primary invasive HER2 negative breast cancer. If HR positive, tumors need to be node positive and diagnosed within the past 10 years. If HR negative, tumors can be node positive or T2-4N0 within 18 months of diagnosis. Subjects who are currently anticoagulated or those with a prior history of GI bleeding, atrial fibrillation, or myocardial infarction are excluded. Subjects who regularly use aspirin (defined as ≥ 5 days per week) need to stop 30 days prior to enrollment. Updated accrual numbers will be given at the time of presentation. Clinical trial information: NCT02927249.
NRG Oncology/NSABP B-51/RTOG 1304: Phase III trial to determine if chest wall and regional nodal radiotherapy (CWRNRT) post mastectomy (Mx) or the addition of RNRT to whole breast RT post breast-conserving surgery (BCS) reduces invasive breast cancer recurrence-free interval (IBCR-FI) in patients (pts) with pathologically positive axillary (PPAx) nodes who are ypN0 after neoadjuvant chemotherapy (NC).

TPS600 Background: This phase III post-NC trial evaluates if CWRNRT post-Mx or whole breast irradiation (WBI) with RNRT after BCS significantly reduces the IBCR-FI rate in pts with PPAx nodes that are pathologically negative after NC. Secondary aims are OS, LRR-FI, DR-FI, DFS-DCIS, second primary cancer, and comparison of RT effect on cosmesis in reconstructed Mx pts. Correlative science examines RT effect by tumor subtype, molecular outcome predictors for residual disease, and predictors for the degree of reduction in loco-regional recurrence. Methods: Clinical T1-3, N1 IBC PPAx nodes (FNA or core needle biopsy) pts complete ≥8 weeks of NC (anthracycline and/or taxane). HER2+ pts receive anti-HER2 therapy. Following NC, BCS or Mx, sentinel node biopsy (≥2 nodes) and/or Ax dissection with histologically negative nodes is performed. ER/PR and HER-2neu status before NC is required. Pts may receive appropriate adjuvant systemic therapy. Radiation credentialing with a facility questionnaire/case benchmark is required. Random assignment for Mx pts is to no CWRNRT or CWRNRT and for BCS pts to WBI or WBI+RNRT. Statistics: 1,636 pts are to be enrolled over 5 yrs (definitive analysis at 7.5 yrs). Study is powered at 80% to test that RT reduces the annual hazard rate of events for IBCR-FI by 35% for an absolute risk reduction of 4.6% (5-yr cumulative rate). Intent-to-treat analysis with 3 interim analyses (43, 86, and 129 events) and a 4th/final analysis at 172 events. Pt-reported outcomes focusing on RT effect will be provided by 736 pts before random assignment and at 3, 6, 12, and 24 mos. Accrual as of 2-7-19 is 1,164 (71.1%).

TPS601 Background: Although ER+/HER2− breast cancer (BC) has better overall prognosis than other subtypes, a high-risk subpopulation is characterized by high-grade tumors, decreased sensitivity to endocrine therapy (ET), higher responsiveness to chemotherapy (CT), and worse prognosis. Based on prior studies, increased pathological complete response (pCR) rates after neoadjuvant CT may have a substantial impact for patients with high-risk, early-stage HR+/HER2− BC. KEYNOTE-756 (ClinicalTrials.gov, NCT03725059) is a global, randomized, double-blind, phase 3 study of pembrolizumab (vs placebo) + CT as neoadjuvant treatment followed by pembrolizumab (vs placebo) + ET as adjuvant treatment for patients with high-risk, early-stage ER+/HER2− BC. Methods: Patients with T1c-2 cN1-2 (tumor size ≥2 cm) or T3-4 cN0-2 grade 3, invasive, ductal ER+/HER2− BC will be stratified by lymph node involvement (positive vs negative), tumor PD-L1 status (positive [CPS≥1] vs negative [CPS < 1]), ER positivity (ER+ ≥10% vs ER+ < 10%), and anthracycline dosing schedule (every 3 weeks [Q3W] vs Q2W), then randomized 1:1 to neoadjuvant treatment with pembrolizumab 200 mg Q3W or placebo combined with paclitaxel (80 mg/m2 Q1W) for 4 cycles followed by doxorubicin (60 mg/m2) or epirubicin (100 mg/m2), each with cyclophosphamide (600 mg/m2) Q2/3W for 4 cycles. After definitive surgery (± radiation therapy, as indicated), patients will receive adjuvant treatment of pembrolizumab (200 mg Q3W) or placebo for 9 more administrations combined with ET, which can be given for up to 10 years. There will be no crossover between treatment arms when moving from neoadjuvant to adjuvant treatment. Dual primary endpoints are pCR rate (ypT0/Tis ypN0) and event-free survival (EFS). Secondary endpoints include ypT0/Tis and ypT0 ypN0 pCR rates in all patients and all 3 pCR definitions in those with PD-L1+ tumors, EFS in patients with PD-L1+ tumors, overall survival, safety, and health-related quality of life. Interim analyses are planned. Enrollment is currently ongoing. Clinical trial information: NCT03725059.

TPS602 Background: Biomarker low risk, ER positive (+), HER2 negative (-) breast cancer with low burden nodal involvement may be associated with good outcomes (Woodward 2016, Mamounas 2017). There is conflicting data regarding the efficacy of regional radiotherapy after breast conserving surgery (BCS) or mastectomy in these patients (Kyndi 2008, Whelan 2015, Poortmans 2015, Liu 2015). Our hypothesis is that the risk of recurrence in patients with biomarker low risk, ER+, Her2- breast cancer and involvement of 1-3 lymph nodes where regional RT is omitted will not be inferior to the risk of recurrence in patients treated with regional RT. Methods: MA39 is a Canadian Cancer Trials Group led, NCTN sponsored, randomized phase III study comparing breast cancer recurrence free interval (BCRFI) in patients with ER+, Her2-, LN 1-3+ breast cancer that is low risk as defined by Oncotype Dx Recurrence Score < 18. Secondary objectives include a comparison of DFS, breast cancer mortality, OS, locoregional and distant recurrence free intervals, toxicity, arm volume and mobility measurements, patient reported outcomes and cost effectiveness. Key eligibility criteria include: age ≥ 40 years; BCS or mastectomy with axillary dissection and 1-3 positive axillary nodes; BCS and SLNB alone and 1-2 positive axillary nodes; mastectomy and SLNB alone and only 1 positive axillary node; planned endocrine therapy ≥ 5 years; adjuvant chemotherapy allowed. Statistical design: The primary analysis will be a test of non-inferiority (NI) in the intention to treat population. If the upper bound of a one-sided 95% interval for the hazard ratio for BCRFI is < 1.4, NI will be declared. Using a one-sided α of 0.05 and a power of 87%, it is anticipated that 278 events are required. With an expected 5 years of accrual and 4.5 years of follow-up, 2140 patients are needed for the final sample size. Conduct to Date: Study activation May 30 2018. Participation as of February 2019: Registrations 64 Randomizations 26. CIRB approval for continuation of MA.39 was received on January 11 2019. Clinical trial information: NCT03488693.

TPS603 Background: Retrospective data suggest breast cancer-specific survival rates with versus without surgery in patients with low-grade ductal carcinoma in situ (DCIS) are similar. Some DCIS patients have a low likelihood of progression to invasive cancer, but predicting who is at risk has not been established. Thus, treatment with a well-balanced risk / benefit ratio has not been achieved. Four active surveillance clinical trials for low risk DCIS have commenced in the United Kingdom (LORIS), Europe (LORD), United States (COMET), and Japan (LORETTA). We aim to examine the effectiveness & safety of active surveillance compared with surgical based treatment approaches for low-risk DCIS patients. Methods: Non surgical approaches are of the two types; active surveillance (AS) alone and AS + endocrine therapy (ET). In the randomized trials LORIS and LORD, the study arms are AS only, but while ET is an option in COMET, ET is mandatory in the single arm trial LORETTA. COMET and LORETTA have broader inclusion criteria as compared to LORIS and LORD. In COMET, comedo necrosis is eligible. In LORETTA, findings other than calcification on mammography (MMG) are also eligible (e.g. low echo area on breast ultrasound). Leaders of the four trials hold regular meetings to foster international DCIS trials collaboration to share information.

TPS6092 Background: Approximately 25% of patients (pts) with NPC develop RM disease, which has a poor prognosis (median overall survival [mOS]: 12–16 mo), despite standard treatments with radiation and/or chemotherapy. NPC is an EBV-associated cancer in which programmed cell death ligand 1 (PD-L1) expression is upregulated upon EBV activation. Pembro showed antitumor activity in a phase 1b study of pts with RM-NPC (objective response rate [ORR]: 26%; mOS: 16.5 mo) (Hsu, J Clin Oncol 2017;35:4050-56). Targeting RM EBV+ NPC with tab-cel immunotherapy (off-the-shelf, allogeneic EBV-specific T cells) in pts has also shown promise, with 2-yr OS rates of 84% (Prockop, ASCO 2016;34:3012). The favorable safety profile of tab-cel offers the opportunity for combination immunotherapy with pembro for increased efficacy. Methods: This multicenter, open-label, single-arm phase 1b/2 study evaluates safety and efficacy of tab-cel in combination with pembro. Study participants are ≥12 yrs of age with incurable, locally recurrent or metastatic EBV+ NPC previously treated with platinum-containing therapy. Pts are checkpoint-inhibitor naïve (phase 1b/2) or refractory to anti-PD-1 or anti-PD-L1 therapy (phase 1b). Tab-cel is selected from a bank based on matching ≥2 HLA alleles, including ≥1 restricting HLA allele, between pts and donors. Tab-cel will be administered intravenously (IV) on days 1, 8, and 15 of a 21-day cycle. Initial tab-cel dose is 2x106 cells/kg and the de-escalated tab-cel dose (if needed) is 1x106 cells/kg. Pembro is administered at 200 mg IV Q3W in adults and 2 mg/kg IV Q3W in pts aged 12 to 17 yrs. Primary outcomes of phase 1b are to characterize dose-limiting toxicities, identify the maximum tolerated dose (MTD) or in the absence of MTD, the recommended phase 2 dose, and assess safety. Primary outcomes for phase 2 are ORR and safety. Secondary endpoints include progression-free survival, OS, and duration of response. Enrollment is ongoing for 12-24 participants in the phase 1b portion of the study with a 6+6 design. Phase 2 is expected to enroll 36 pts. Clinical trial information: NCT03769467.

Published: May 2019

TPS6094 Background: rHNSCC commonly affects local or regional sites and is associated with considerable morbidity and mortality. Outcomes of these patients remain poor with limited curative treatment options and low response rates. New modalities that are targeted, minimally invasive, and provide improved tumor response and control while having limited systemic side effects are needed. Photoimmunotherapy (PIT) is a new cancer-targeted platform technology. It is a combination drug and device treatment that utilizes monoclonal antibodies conjugated to a dye (IRDye 700DX) that is photoactivated using nonthermal red light to induce rapid and selective tumor cell death. The objective of this phase 3 study is to evaluate the efficacy and safety of ASP-1929 (EGFR-directed antibody cetuximab-IR700 conjugate) PIT treatment as a monotherapy in patients with locoregional rHNSCC. Methods: A global, multicenter phase 3, randomized, double-arm, open-label, controlled trial of ASP-1929 PIT vs physician’s choice standard of care (SOC) for the treatment of locoregional, rHNSCC in patients who have failed or progressed on or after at least two lines of therapy, of which at least one line must be systemic therapy, is currently underway. Primary endpoints of the study are PFS and OS and the key secondary endpoint is ORR. Key inclusion criteria include: disease not amenable to curative therapy; tumor(s) accessible for PIT light treatment and measurable by CT or MRI; male or female ≥ 18 yrs old with life expectancy > 6 months; ECOG score of 0 to 1. Key exclusion criteria include: history of ≥ Grade 3 cetuximab infusion reaction; distant metastatic disease; tumors invading a major blood vessel unless embolized. The study will include ~275 subjects in a 2:1 randomization (ASP-1929 PIT: Physician’s choice SOC). The physician’s choice SOC arm includes cetuximab, methotrexate, or docetaxel. Tumor(s) are illuminated with 690 nm PIT light treatment 24 hrs following completion of ASP-1929 infusion (640 mg/m²). Clinical trial sites will be in the USA, EU and Asia. Clinical trial information: NCT03769506.

Published: May 2019

TPS6097 Background: Treatment options are limited for patients with RAI-refractory DTC that is resistant to VEGFR-targeted therapy. Cabozantinib inhibits receptor tyrosine kinases including VEGFR2, MET, AXL, and RET, which are implicated in the development of DTC, and has shown clinical activity in early-phase studies of patients with RAI-refractory DTC. This study evaluates the efficacy and safety of cabozantinib in patients with RAI-refractory DTC who have progressed during or after prior VEGFR-targeted therapy. Methods: This is a phase 3, multicenter, randomized, double-blind, placebo-controlled trial (NCT03690388). The co-primary endpoints are progression-free survival and objective response rate evaluated by blinded independent radiology committee (BIRC) per RECIST v 1.1. Additional endpoints include safety, overall survival, quality of life, and changes in relevant biomarker levels (eg, thyroglobulin). Approximately 300 patients will be randomized in a 2:1 ratio to receive either cabozantinib (60 mg QD orally) or placebo. Randomization is stratified by prior treatment with lenvatinib and age (≤ 65 yrs vs > 65 yrs). Eligible patients must have a pathologic diagnosis of DTC and must have been previously treated with or deemed ineligible for treatment with iodine-131 for DTC. Patients must have received lenvatinib or sorafenib for DTC and progressed during or following treatment with a VEGFR inhibitor. Up to 2 prior VEGFR-targeting TKI agents are allowed. Patients randomized to placebo may be eligible for real time on-study crossover to cabozantinib based on BIRC confirmation of disease progression. Unblinded patients randomized to cabozantinib may continue on study treatment if there is clinical benefit per investigator. Key words: Radioiodine-refractory differentiated thyroid cancer, cabozantinib, VEGFR-targeted therapy, trial-in-progress. Clinical trial information: NCT03690388.
