TPS2572 Background: We demonstrated that low doses of temozolomide (TMZ) administered in a prophylactic, metronomic fashion significantly prevented development of brain metastases in murine models of breast cancer. Based on these findings, we developed a secondary-prevention clinical trial. Methods: Phase I is a standard 3+3 design: T-DM1 3.6mg/kg IV every 21 days plus TMZ 30, 40 or 50 mg/m2 daily, to identify the maximum tolerated dose (MTD) of the combination, and is completing accrual, with 9 patients accrued, currently on the third and last dose level. Phase II will randomize patients to T-DM1 3.6mg/kg versus T-DM1 3.6mg/kg plus TMZ at recommended phase 2 dose (RP2D), to evaluate if addition of TMZ improves the recurrence-free incidence from distant new brain metastases at one year from 50% to 65%. Patients will undergo radiology guided lumbar puncture at baseline and after 6 weeks of treatment (C3D1) for correlative studies, brain MRI, systemic restaging CTs, and questionnaires for evaluation of symptoms and quality of life. Eligibility: HER2+ breast cancer with brain metastases (up to 10 lesions), treated with SRS and/or resection ≤12 weeks before enrollment, no leptomeningeal metastases, no previous WBRT, ECOG ≤2 and adequate organ and marrow function. Biomarkers, including cell free DNA from CSF, serum and tumor block, exosomal DNA, serum markers for neuroinflammation, and patient reported outcomes, will be analyzed in an exploratory fashion. Target accrual: up to 18 patients in phase I and 98 in phase II. Clinical trial information: NCT03190967 .

TPS3160 Background: Immunotherapy with the anti-PD-(L)1 checkpoint inhibitors (CPIs) has been largely ineffective in so-called non-immunogenic “cold tumors”. Facilitating T cell infiltration is necessary to invoke an immune response which may be augmented or complemented by the activity of CPIs like durvalumab. Selective T cell Redirection Proteins (STRs) are fusion proteins that consist of genetically engineered Superantigen (Sag) linked to Fragment antigen binding (Fab) moieties directed to tumor-associated antigens. Nap is a first in class STR compound, recognizing the tumor-associated oncofetal antigen 5T4, whereas the SAg moiety selectively engages the T cell receptor β variable (TRBV) 7-9. Nap has been shown to induce specific T cells expansion, activation and infiltration into the tumor in pre-clinical and clinical studies. Pre-clinical data demonstrated that the combination of STR with CPI may lead to long term durable responses not possible in most patients receiving single agent CPI therapy and suggests that combining CPIs with STR may be a promising therapeutic strategy for patients with solid tumors. Methods: Patients will be treated with the combination of Nap and durvalumab using a flat dose of durvalumab (1120 mg) and the 3+3 design for Nap dose escalation (2, 5, 10, 15 and 20 mcg/kg). The MTD of Nap for the combination treatment will be established based on DLTs occurring during the first treatment cycle. The dose escalation part will be followed by MTD expansion cohort in which 10–15 patients will be treated with MTD of Nap and 1120 mg durvalumab (Clinical trial registry number NCT03983954). Major eligibility criteria include patients with pretreated advanced or metastatic, 5T4 expressing solid tumors, including patients previously progressed on CPI therapy. As of January 2020, enrollment to dose levels 2, 5 and 10 mcg/kg has been completed without DLT, enrollment to dose level 15 mcg/kg will start on February 2020. Clinical trial information: NCT03983954 .

TPS3164 Background: AST-008 is a potent spherical nucleic acid configuration of a toll-like receptor (TLR) 9 agonist oligonucleotide being developed for the treatment of MCC and CSCC in patients (pts) progressing on immune checkpoint inhibitor (CPI) monotherapy. Previously presented data suggests AST-008 elicits a Th1-type cytokine response and immune cell activation. This parallel-arm phase II design will permit assessment of efficacy in two advanced skin cancers with high unmet medical need. Methods: The study has an open label, multicenter phase Ib/II dose escalation/expansion design. The phase 1b dose escalation used a 3+3 design with increasing doses of intratumoral (IT) AST-008 plus standard flat dose pembrolizumab. The phase II dose expansion is using the recommended regimen (RP2D) of IT AST-008 plus flat dose pembrolizumab or cemiplimab to treat two cohorts of pts with advanced/metastatic MCC or CSCC, respectively. The key objective of the phase II expansion is to provide an estimate of preliminary efficacy of IT AST-008 with pembrolizumab or cemiplimab in pts whose disease progressed on a single-agent CPI therapy. Endpoints also include safety, pharmacokinetic and pharmacodynamic assessments. Pts must have at least two evaluable lesions by RECIST v1.1. One or more lesions may be injected with AST-008, but one lesion (the “witness” lesion) must remain un-injected throughout the study to differentially assess effects of AST-008 on the injected and witness lesions. The RP2D of AST-008 was derived from the dose escalation phase together with pembrolizumab. That RP2D is being used not only in the MCC cohort where AST-008 is combined with pembrolizumab, but also in the CSCC cohort where AST-008 is combined with cemiplimab. To ensure safety of the AST-008/cemiplimab combination, the first 6 pts in the CSCC cohort will be monitored for dose limiting toxicities through the first 5 weeks of dosing, and then the data review committee will assess safety before approving additional patient enrollment to that cohort. Each expansion cohort will enroll up to 29 pts with a Simon two-stage optimal design. In the first stage, 10 pts will be accrued. If there are 0 responses in these 10 pts, enrollment in that arm will be stopped. Otherwise, 19 additional pts will be accrued for a total of 29. The null hypothesis will be rejected if 4 or more responses are observed in 29 pts. This design yields a type I error rate of 0.05 and power of 80% when the true response rate is 20%. The planned phase II enrollment is 58 pts across about 15 US-based sites. Clinical trial information: NCT03684785 .

TPS3657 Background: Aberrant glycosylation is a hallmark of cancer. Glycosphingolipids (GSLs), glycans conjugated to a lipid (ceramide) core, are essential for the recruitment of immune-related proteins to specific membrane microdomains. Globo H (GH) is a GSL found on normal cells but highly overexpressed on various epithelial tumors playing a role in tumor development and progression. GH is a promising target for immunotherapy. OBI-999 is an ADC composed of a human recombinant immunoglobulin G (IgG) monoclonal antibody that selectively and specifically binds to GH, attached by a linker to the antimitotic agent monomethyl auristatin E (MMAE). Its mechanism of action is based on tumor-selective delivery of MMAE to GH-expressing tumors with subsequent tumor cell death. Preclinical studies demonstrated that OBI-999 antibody binds specifically to the GH antigen, and antitumor efficacy was noted in breast, gastric, pancreatic, and lung cancer xenograft models. The pharmacokinetics (PK) of OBI-999 were determined in normal and tumor-bearing mice, rats, and monkeys. Exposure of OBI-999 increased proportionally with dose. No sex difference or accumulation was seen. The primary objectives are to determine dose limiting toxicities (DLTs), the maximum tolerated dose (MTD), and the phase 2 recommended dose (P2RD). The secondary objectives are to assess the rates of objective response and clinical benefit, the duration of progression-free survival, the immunogenicity of OBI-999, and the PK and pharmacodynamics (PD) of OBI-999 and MMAE. Methods: In Part 1, a "3+3" dose-escalation part of the study, up to 30 patients with advanced solid tumors refractory to ≥1 line of systemic therapy, who cannot tolerate standard therapy, or for whom no standard treatment is available, regardless of GH status will be treated. OBI-999 will be administered as a 60-minute IV infusion using a dose range of 0.4, 0.8, 1.2, 1.6, and 2.0 mg/kg on day 1 of every 21-day cycle. In Part 2, the cohort-expansion portion of the study, patients will be treated at the MTD or at a lower RP2D as determined by cumulative toxicities and tolerability profile. The study will determine the preliminary clinical activity and safety of OBI-999 in up to 155 patients with advanced solid tumors, pancreatic, gastric, esophageal, and colorectal cancer according to a Simon two-stage phase 2 design. Patients must have GH overexpression defined as an H-score of ≥100 according to an FDA Investigational Device Exempt (IDE) validated IHC assay. Clinical trial information: NCT04084366 .

TPS4120 Background: Adjuvant chemotherapy (ACT) is routinely offered to patients with high risk (HR) stage II or stage III CRC following potentially curative surgery. Over 50% of stage III and > 80% of stage II patients are cured by surgery alone but are being exposed to unnecessary chemotherapy with short- and long-term side effects. Post-operative ctDNA identifies minimal residual disease (MRD) after surgery in CRC. Our national study, TRACC, compares ctDNA guided versus standard of care (SoC) decision making in patients undergoing ACT. Methods: This is a UK-wide, multi-centre, prospective, two-arm, randomised trial. Patients with HR risk stage II or stage III CRC who have undergone R0 resection and have detectable ctDNA in their pre-surgical sample are eligible. Patients who undergo neoadjuvant chemoradiotherapy (CRT) for locally advanced rectal cancer with detectable ctDNA pre-CRT are also eligible. Patients are randomised in a 1:1 ratio to receive either SoC ACT or ctDNA guided ACT. In the ctDNA guided arm, patients who are ctDNA negative post-operatively have chemotherapy de-escalated i.e., 3 months(m) of Capecitabine and Oxaliplatin (CAPOX) doublet ACT is reduced to 3 m single agent Capecitabine; 6 m single agent Capecitabine reduced to no chemotherapy. In this group, ctDNA is re-tested at 3 months and if detectable, patients receive 3 months of CAPOX. Primary end-point is 3-year disease free survival (DFS). Secondary end-points include overall survival, neurotoxicity, quality of life and health economics. Based on a standard 3-year DFS of 75% in SoC ACT arm, to demonstrate a non-inferiority margin of 1.25, 810 patients are required per arm (85% power, α = 0.1). Stratification is by tumour staging and site of primary tumour. Target accrual is over 4 years. The study opened to recruitment in January 2020 and is supported by the MRC-NIHR Efficacy and Mechanism Evaluation Grant ( NIHR128529 ). Clinical trial information: NCT04050345 .

Published: May 2020

TPS4662 Background: Adenosquamous pancreatic cancer (ASQ) constitutes 1-5% of all pancreatic cancers and compared to pancreatic adenocarcinoma (PDAC) has a worse survival. ASQ has glandular and squamous histologic components and given its rarity and aggressiveness, in practice there is no current standard regimens for ASQ. Unfortunately, checkpoint blockade has had an overall disappointing impact on survival in PDAC. In an effort to identify a patient subgroup most likely to respond to immunotherapy, the immune tumor microenviroment (TME) in ASQ was evaluated. Tissue microarrays from archived ASQ samples were first created. Then immunocytochemistry (IHC) staining for immune cells and immune checkpoint proteins was performed. PD-L1 expression and the combined presence of PD-L1+, IDO+, LAG3+, and VISTA+ was seen. All ASQ cases had some degree of tumor infiltrating lymphocytes (TIL, including CD8+ T-cells). Furthermore, PD-L1 and other checkpoint positivity correlated with increased TIL. These findings suggest the presence of adaptive immune resistance. This is in contrast to standard PDAC, in which the expression of immune checkpoints is rarely accompanied by increased effector T-cells. Methods: We are conducting a multiple-center, single arm, phase II clinical trial to evaluate PD-1 inhibition with INCMGA00012 in locally advanced unresectable and metastatic ASQ patients. INCMGA00012 is a humanized monoclonal antibody antagonistic to PD-1. The primary objective is to determine the disease control rate at 4 months using RECIST 1.1. The study is planned with 21 evaluable subjects and allows early termination for lack of efficacy. Patients have a pre-treatment biopsy followed by INCMGA00012 500 mg on Day 1 of each cycle (every 4 weeks). A second biopsy will occur eight weeks later. Eligibility criteria includes histologically- or cytologically-proven adenosquamous carcinoma of the pancreas by central pathologic review and patients must have received (or been intolerant to or ineligible for) at least 1 prior line of cytotoxic chemotherapy and received no more than 2 prior systemic treatments. Patients with known MSI-H/dMMR status are excluded. Exploratory objectives include examining changes in the TME checkpoint expression and immune cell infiltrate in the biopsies via IHC and RNA expression studies. The clinical study was activated in February 2020. Clinical trial information: NCT04116073 .

TPS4665 Background: Pancreatic cancer is a malignant tumor with limited therapeutic strategies and poor prognosis. About 60% of the patients have metastasis disease at time of diagnosis and lose the opportunity for surgery. Thus, therapy based on drugs becomes a vital part in pancreatic cancer. In 2013, MPACT showed that albumin-bound paclitaxel combined with gemcitabine in the treatment of metastatic pancreatic cancer could increase the mOS from 6.6 months to 8.7 months (HR = 0.72, 95% CI: 0.62-0.83; P < 0.001). Nowadays, the immunosuppressive checkpoint inhibitors acting on PD-1/PD-L1 pathway have shown a significant efficacy in enhancing tumor immune surveillance and anti-tumor immune response. In 2018, two studies reported in ASCO showed the preliminary efficacy of albumin paclitaxel, gemcitabine and PD-1 inhibitor in the treatment of advanced pancreatic cancer. Among patients who have not received treatment before, the disease control rate was even up to 100%. Therefore, this study will further explore the domestic PD-1 antibody combined with albumin-bound paclitaxel and gemcitabine as the first-line treatment of advanced pancreatic cancer among Chinese pancreatic cancer patients. Methods: This is a prospective, single-armed, exploratory, investigator initiated trial to explore the efficacy and safety of PD-1 antibody combined with albumin-bound paclitaxel and gemcitabine as first-line treatment of metastatic pancreatic cancer. This study is, to our knowledge, the first one to test the efficacy and safety of PD-1 antibody on metastatic pancreatic cancer patients among Chinese population. Survival index is median survival estimated by Kaplan-Meier and draw the survival curve. The response rate was compared by χ 2 test / Fisher test. All primary and secondary outcomes will be analyzed on the full analysis set. PD-1 antibody, 200mg, D1 administration; paclitaxel (albumin binding type), 125mg/m2, D1, 8 days administration; gemcitabine, 1000mg/m2, D1, 8 days administration, every 21 days as a cycle and PD-1 antibody (200mg, D1, every 21 days) single drug maintenance treatment is given after the completion of 6 cycle chemotherapy. Major eligibility criteria is that each participant must have metastatic pancreatic cancer confirmed by histology or cytology and has never received systemic anti-tumor therapy before. So far, 11 of planned 20 patients have been enrolled. Clinical trial information: NCT04181645 .

Published: May 2020

TPS4673 Background: Pancreatic cancer is a poor prognosis and fast-growing cancer, whose five-year survival is 6% in Europe and the US. FOLFIRINOX has been established as the reference medical treatment for this disease worldwide, yet it also causes leuko-neutropenia, thrombocytopenia, diarrhea, anorexia, asthenia, weight loss, and peripheral sensory neuropathy. Its indication is usually limited to patients having a WHO performance status of 0 or 1. This treatment is often interrupted once Grade 3-4 clinical or hematological toxicities occur, resulting in poor patient performance status and quality of life. Presently, no prospective study monitor and evaluate the qualitative and quantitative effects of FOLFIRINOX on the daily life of pancreatic cancer patients in real-time. Such monitoring would provide early warning signals for the identification of any improvement or deterioration of the patient condition. Whenever necessary, proactive interventions would be triggered to avoid emergency hospitalization for severe adverse events and to enhance treatment compliance. Methods: Our study involves the use of the mobile e-Health platform PiCADo (JMIR 2018) to track and analyse circadian rhythms, symptoms, and body weight in real time in 45 advanced pancreatic cancer patients at 4 centres. The patients are continuously telemonitored for rest-activity, temperature and 3D-orientation via a BLE sensor during the six weeks following the first FOLFIRINOX course. Patients weigh themselves daily on a BLE scale and self-rate their symptoms using a touchscreen on GPRS tablet. Alerts are generated according to preset yet modifiable thresholds of automatically computed critical parameters. From these data, we will evaluate the rate of emergency hospital admissions and the admission-free survival, the rates of severe adverse events, patients’ symptoms dynamics, and their relations with the disruption of the patients’ circadian rhythm. Patient satisfaction and research experience will also be assessed, since engagement is at the core of the success of the approach. The results will guide a future randomized trial comparing standard pancreatic cancer patient care with a personalized FOLFIRINOX approach, including chronotherapy delivery.

TPS5091 Background: Immuno-oncology (IO) therapies have revolutionized the treatment (tx) of pts with advanced bladder cancer (advBC). For pts with cisplatin-eligible, muscle invasive BC (MIBC), the recommended tx is cisplatin-based neoadjuvant chemotherapy (NAC) prior to radical cystectomy (RC). However, since only ≈ 30% of pts achieve a pathologic complete response (pCR) translating to improved long-term outcomes with approved regimens, new therapies are needed. PD-L1 expression is associated with aggressive BC and has been shown to increase in BC after NAC, supporting the therapeutic pursuit of the PD-1/PD-L1 axis. Additionally, expression of indoleamine 2,3-dioxygenase (IDO) is higher in BC than in normal bladder tissue and is associated with advanced disease and poor clinical outcome. Linrodostat mesylate, a selective, potent, once-daily oral IDO1 inhibitor that works to reduce kynurenine production, has demonstrated clinical activity in combination with NIVO (anti–PD-1) in pts with IO tx–naive advBC who had ≥ 1 prior line of therapy (ORR, 37%). Taken together, these data provide a rationale for investigating NAC + NIVO + linrodostat in MIBC. Here we describe a randomized, partially blinded, phase 3 study evaluating the efficacy and safety of NAC ± NIVO ± linrodostat followed by RC and continued IO tx in pts with MIBC (NCT03661320). Methods: Pts aged ≥ 18 years with previously untreated MIBC (clinical stage T2-T4a, N0, M0), creatinine clearance ≥ 50 mL/min, and predominant UC histology who are eligible for cisplatin-based NAC and RC will be enrolled. Pts with evidence of positive lymph node; metastatic BC; or prior systemic therapy, radiotherapy, or surgery for BC other than TURBT are not eligible. Pts will be randomized to receive NAC (gemcitabine/cisplatin; arm A), NAC + NIVO + oral placebo (arm B), or NAC + NIVO + linrodostat (arm C) followed by RC (all arms); arms B and C will receive continued IO tx. Primary endpoints include pCR after neoadjuvant tx and event-free survival (arms C vs A; arms B vs A). Secondary endpoints are overall survival and safety. This global study in 28 countries began accrual in Nov 2018 and has a target enrollment of 1200 pts. Clinical trial information: NCT03661320 .
