Project description:Purpose: This open-label, investigator-initiated, phase II study was conducted to evaluate the safety, survival and neoadjuvant outcomes of NAC combined with dual immune checkpoint inhibitors in advanced-stage EOC. Patients and methods: Between June 2019 and July 2021, 45 patients with unresectable stage III-IV EOC were enrolled. The patients received three cycles of NAC combined with durvalumab and tremelimumab. All patients underwent interval debulking surgery and received three cycles of durvalumab and adjuvant chemotherapy, followed by 12 cycles of durvalumab as maintenance therapy. The primary endpoint was the 12-month progression-free survival (PFS) rate; the secondary endpoints were the objective response rate (ORR) after NAC, a chemotherapy response score (CRS), pathologic complete response (pCR), overall survival (OS), and safety. The pre-planned exploratory analyses assessed the lymphocyte infiltration, PD-L1 expression, and genomic profiles of pre-treatment tumors.

Computational design of improved standardized chemotherapy protocols for grade II oligodendrogliomas
Víctor M. Pérez-García, Luis E. Ayala-Hernández, Juan Belmonte-Beitia, Philippe Schucht, Michael Murek, Andreas Raabe, Juan Sepúlveda. PLoS Comput Biol. 2019 Jul; 15(7): e1006778.
Abstract:
Here we put forward a mathematical model describing the response of low-grade (WHO grade II) oligodendrogliomas (LGO) to temozolomide (TMZ). The model describes the longitudinal volumetric dynamics of tumor response to TMZ of a cohort of 11 LGO patients treated with TMZ. After finding patient-specific parameters, different therapeutic strategies were tried computationally on the ‘in-silico twins’ of those patients. Chemotherapy schedules with larger-than-standard rest periods between consecutive cycles had either the same or better long-term efficacy than the standard 28-day cycles. The results were confirmed in a large trial of 2000 virtual patients. These long-cycle schemes would also have reduced toxicity and defer the appearance of resistances. On the basis of those results, a combination scheme consisting of five induction TMZ cycles given monthly plus 12 maintenance cycles given every three months was found to provide substantial survival benefits for the in-silico twins of the 11 LGO patients (median 5.69 years, range: 0.67 to 68.45 years) and in a large virtual trial including 2000 patients. We used 220 sets of experiments in-silico to show that a clinical trial incorporating 100 patients per arm (standard intensive treatment versus 5 + 12 scheme) could demonstrate the superiority of the novel scheme after a follow-up period of 10 years. Thus, the proposed treatment plan could be the basis for a standardized TMZ treatment for LGO patients with survival benefits.

Project description:We hypothesised that in esophagogastric junction adenocarcinomas combining molecular predictive biomarkers with FDG-PET would optimise response prediction. Changes in FDG uptake in tumours meaured by PET scans after 14 days of chemotherapy define metabolic responders and non-responders. However while <5% of metabolic non-responders will go onto have a response to the full 9-12 week chemotherapy protocol providing a high negative predictive value for FDG-PET, the positive predictive value of metabolic response is more limited. Only 50% of those patients that have a metabolic response determined by FDG PET at day 14 will go on to subsequently have a response to the full 9-12 week chemotherapy protocol . We used global gene expression profiling to identify molecular biomarkers that when combined with FDG-PET would improve predictive accuracy, in particular we aimed to identify molecular biomarkers that could sub-classify FDG PET defined metabolic responders into those that did and did not subsequently go on to have a radiological response and hence clinical benefit from the full chemotherapy protocol. Patients with stage IB-IV esophagogastric junction adenocarcinomas(n=28) received platinum combination chemotherapy .FDG-PET CT scans were performed at baseline and day 14 and expression profiling (Affymetrix ST1.0 Exon Genechips) on baseline tumour biopsies. 14 patients were classified as FDG-PET metabolic responders and gene expression was analysed in these tumour specimens to determine differences between those that did subsequently go on to have a radiological response (n=10) or did not have a radiological response (n=4) to the full 9-12 week chemotherapy protocol. A tissue microarray(n=154 esophagogastric adenocarcinomas who underwent surgery+/-neoadjuvant chemotherapy)was used with immunohistochemistry for qualification of gene expression profiling results. Radiological response was assessed after 3or4 cycles of chemotherapy by RECISTv1.1.

Project description:We evaluated the efficacy and feasibility of pembrolizumab combined with chemotherapy in frontline management of advanced high-grade epithelial ovarian cancer (EOC). Additionally, chemotherapy-induced changes in the tumor microenvironment and biomarkers of response were evaluated. In this single-arm phase II trial, eligible patients received up to 4 cycles of neoadjuvant chemotherapy followed by interval cytoreduction; then, adjuvant intravenous carboplatin/weekly paclitaxel/pembrolizumab was given for 3 cycles and maintenance pembrolizumab until progression or toxicity (maximum 20 cycles). The primary endpoint was progression-free survival (PFS). Secondary endpoints included feasibility, toxicity, and overall survival (OS). PD-L1 staining, multiplex immunofluorescence staining, RNA-sequencing, reverse phase protein array analyses were performed on pre- and post-chemotherapy samples. Thirty-one eligible patients were enrolled. Median PFS was 14.88 months overall (95% CI 12.40 – 23.00). Among those with PD-L1 Combined Positive Score (CPS), the median PFS and OS were not reached compared to those with CPS<10 (10.50 and 30.90 months, respectively). All patients who initiated chemotherapy with pembrolizumab therapy completed their planned adjuvant cycles. Treatment discontinuation due to immune-related toxicity occurred in 6 patients (20%). Chemotherapy resulted in an infiltration of anti-tumor immune cells in the tumor microenvironment. Samples of patients with the best PFS demonstrated increased expression of NF-κB, TGF-β, and β-catenin signaling. In conclusion, pembrolizumab with chemotherapy was feasible and resulted in PFS within the historical range for this EOC population. Patients with CPS≥10 may benefit more from this regimen and future studies should investigate this potential biomarker. Funding for this investigator-initiated trial was provided by Merck. Clinicaltrials.gov: NCT02520154.

Project description:<p>LGL leukemia can be divided into three subsets including the following: αβ or γδT-LGL and NK-LGL leukemia. All three subtypes will be enrolled using a two-stage design. The primary endpoint of the study is assessment of overall clinical response. Correlative laboratory studies will be performed aimed at determining the mechanism of response to treatment. Thirteen participants will be accrued in the first stage at a dose of 300 mg BID administered intermittently every other week (i.e., 7 days on and 7 days off). If there are two or more responders, the protocol will be extended to a second stage of the study and accrual will be extended to 25 evaluable participants. Allowing for 10% rate of ineligibility due to unexpected events and dropout, we will accrue 14 patients in the first stage and 27 patients in total. Participants that withdraw from the study for reason unrelated to toxicity, will be replaced. There are two potential stopping rules for toxicity.</p> <p>If 3 or more participants out of the 13 enrolled in the first stage experiences grade IV neurotoxicity, the study will be stopped due to excessive toxicity. Dose reductions have been incorporated for hematologic toxicity. Treatment of T and NK LGL leukemia with immunosuppressive agents such as low-dose methotrexate generally require from four to six months for a clinical response and sometimes much longer. Therefore, in participants who show clinical improvement with less than grade three toxicity, tipifarnib treatment will be continued for as many as four additional months (12 months total). After the first 8 months, response will be assessed. The protocol treatment will be discontinued in participants with progression of disease. A long-term follow up will be performed for five years in patients that receive a complete clinical response. The long-term follow up will consist of vital signs, weight, CBCs, serum chemistries, and physical examination at six month intervals.</p>

Project description:<p>The SUCCESS-A Study (<a href="http://www.success-studie.de">http://www.success-studie.de</a>) is a randomized Phase III study of response to treatment of early primary breast cancer with adjuvant therapy after surgical resection. The primary outcome is disease-free survival and secondary outcomes are overall survival and toxicity. The study design includes comparison of two pairs of treatment regimes performed in sequence. The first randomization contrasts treatment with and without Gemcitabine (3 cycles of Epirubicin-Fluorouracil-Cyclophosphamide(FEC)-chemotherapy, followed by 3 cycles of Docetaxel(D)-chemotherapy versus 3 cycles of Epirubicin-Fluorouracil-Cyclophosphamide(FEC), followed by 3 cycles of Gemcitabine-Docetaxel(DG)-chemotherapy). The second randomization contrasts treatment with Zoledronate for two versus five years. Patients were recruited from 2005 to 2007 and a total of 3754 patients were included from 250 study sites across Germany. Genome-wide SNP microarray data and phenotype outcomes for the first phase of the study (treatment with and without Gemcitabine) are included in the GARNET (Genomics and Randomized Trials Network) pharmacogenomic study in this dbGaP submission. (The Zoledronate treatments are still underway).</p> <p>SUCCESS-A is a an open-label, multicenter, 2x2 factorial design, randomized controlled, Phase III study comparing the disease free survival after randomization in patients treated with 3 cycles of Epirubicin-Fluorouracil-Cyclophosphamide(FEC)-chemotherapy, followed by 3 cycles of Docetaxel(D)-chemotherapy versus 3 cycles of Epirubicin-Fluorouracil-Cyclophosphamide(FEC), followed by 3 cycles of Gemcitabine-Docetaxel(DG)-chemotherapy, and to compare the disease free survival after randomization in patients treated with 2 years of Zoledronate versus 5 years of Zoledronate in patients with early primary breast cancer. Patients were required to have histopathological proof of axillary lymph node metastases (pN1-3) or high risk node negative, defined as: pT>2 or histopathological grade 3, or age , ≤ 35 or negative hormone receptor, but were not allowed to have evidence of distant disease. Patients were entered into the study no later than 6 weeks after complete resection of the primary tumor. No antineoplastic treatment other than surgical treatment, the defined cytotoxic and endocrine treatment, and radiotherapy was allowed prior to study entry and during the course of the study. After surgery, leading to complete resection of the invasive and intraductal components of the primary tumor, patients were randomized to one of the following two treatments for the first phase of the project (which is included in this GARNET pharmacogenomics study):</p> <p><b>AA</b>: 3 cycles of 5-Fluorouracil 500 mg/m² i.v. body surface area and Epirubicin 100 mg/m² i.v. and Cyclophosphamide 500 mg/m² i.v., (FEC100), each administered on day 1, repeated on day 22, subsequently followed by 3 cycles of Docetaxel 75 mg/m² body surface area i.v. (D), and Gemcitabine 1000 mg/m² i.v. (30 min infusion) (G), administered on day 1, followed by Gemcitabine 1000 mg/m² i.v. (30 min infusion) on day 8, repeated on day22</p> <p><b>AB</b>: 3 cycles of 5-Fluorouracil 500 mg/m² i.v. body surface area and Epirubicin 100 mg/m² i.v. and Cyclophosphamide 500 mg/m² i.v., (FEC100), each administered on day 1, repeated on day 22, subsequently followed by 3 cycles of Docetaxel 100 mg/m² body surface area i.v. (D), administered on day 1, repeated on day 22</p> <p>A second randomization was made for assigning patients to one of the following two subsequent treatments for the second phase of the project (NOT included in the pharmacogenetic study in this dbGaP submission):</p> <p><b>BA</b>: Zoledronic acid 4 mg i.v., every 3 months for the duration of two years, subsequently followed by zoledronic acid 4 mg i.v., every 6 months for the duration of additional three years</p> <p><b>BB</b>: Zoledronic acid 4 mg i.v., every 3 months for the duration of two years</p> <p>Patients with positive hormone receptor status (≥10% positively stained cells for estrogen and/or progesterone) of the primary tumor were recommended to receive Tamoxifen treatment 20 mg p.o. per day for 2 years, after the end of chemotherapy . Subsequent to chemotherapy, postmenopausal patients with positive hormone receptor status were recommended to be treated with Anastrozole (Arimidex®) 1 mg p.o. for additional 3 years, premenopausal patients will continue Tamoxifen treatment for those additional 3 years. In addition to tamoxifen, all patients with positive hormone receptor status of the primary tumor and under the age of 40 or restart of menstrual bleeding within 6 months after the completion of cytostatic treatment or with premenopausal hormone levels as defined below were recommended to receive Goserelin (Zoladex®) 3.6 mg subcutaneously every 4 weeks over a period of 2 years following chemotherapy. Premenopausal endocrine status will be assumed, if the following serum levels are met: LH < 20 mIE/ml, FSH < 20 mIE/ml and E2 > 20 pg/ml. Endocrine therapy will start after the end of chemotherapy.</p> <p>All patients with breast conserving therapy or more than 3 axillary lymph node metastases or in the following cases after mastectomy will receive adjuvant radiotherapy: T3/T4-carcinoma, T2-carcinoma > 3 cm, multicentric tumor growth, lymphangiosis carcinomatosa or vessel involvement, involvement of the pectoralis fascia or a safety margin < 5 mm. Radiotherapy was usually performed after the chemotherapy and parallel to the beginning of the zoledronic acid therapy.</p> <p>Initially, DNA was extracted for performing SNP microarray assays using blood collected at baseline prior to the first randomization. However, the first set of SNP microarray results indicated a quality problem with approximately 50% of the DNA samples. A majority of the problematic samples were replaced with DNA extracted from redrawn blood. The remaining problematic samples were 'restored' using an Illumina FFPE Restoration procedure. A total of 3322 subjects (1638 from arm AA and 1684 from arm AB) were successfully genotyped. Among those, 1771 were from original blood samples, 1092 from redrawn blood samples and 459 from restored blood samples.</p> <p>The SUCCESS-A study is part of the Genomics and Randomized Trials Network (GARNET, <a href="http://www.garnetstudy.org">http://www.garnetstudy.org</a>) funded by the National Human Genome Research Institute (NHGRI). The overarching goal is to identify novel genetic factors that contribute to disease-free survival for breast cancer patients using different forms of chemotherapy through large-scale genome-wide association studies of treatment response in randomized clinical trials. The study was conducted at the University Hospital Erlangen, Friedrich-Alexander University Erlangen-Nuremberg, Germany. Genotyping was performed at the Johns Hopkins University Center for Inherited Disease Research (CIDR). Data cleaning and harmonization were performed at the GARNET Coordinating Center at the University of Washington.</p>
