Nab-paclitaxel/carboplatin (nab-PC) and gemcitabine/carboplatin (GC) are the standard first-line chemotherapy in non-small cell lung carcinoma. Up to now, there is no head to head trial to compare nab-PC with GC in advanced squamous cell lung carcinoma.
The primary objective of this study was to determine the recommended dose of the vascular disrupting agent, BNC105P, in combination with gemcitabine and carboplatin in patients with ovarian cancer in first or second relapse with a minimum 4 month progression-free interval after last platinum.
Triple-negative breast cancer (TNBC) patients usually present worse clinical outcomes due to their high heterogeneity. The purpose of our study is to investigate the prognostic role of AR and BRCA1 expression in sporadic TNBC patients, and effect of AR blockade and PARP1 inhibitor for TNBC patients who characterized by positive-AR expression and BRCA1 inactivation or dysfunction. In our present study, we found that AR is expressed in 43.6% and 34.0% of TNBC tissues, when 1% or 10% staining was used as the t...
Carboplatin is a first-line treatment for ovarian cancer. However, most patients develop resistance and undergo disease recurrence. This study aims to explore the relationship between the expression of X-linked inhibitor of apoptosis protein (XIAP) and carboplatin sensitivity in ovarian cancer.
Neoadjuvant plus adjuvant or only adjuvant nab-paclitaxel plus gemcitabine for resectable pancreatic cancer - the NEONAX trial (AIO-PAK-0313), a prospective, randomized, controlled, phase II study of the AIO pancreatic cancer group.
Even clearly resectable pancreatic cancer still has an unfavorable prognosis. Neoadjuvant or perioperative therapies might improve the prognosis of these patients. Thus, evaluation of perioperative chemotherapy in resectable pancreatic cancer in a prospective, randomized trial is warranted. A substantial improvement in overall survival of patients with metastatic pancreatic cancer with FOLFIRINOX and nab-paclitaxel/gemcitabine vs standard gemcitabine has been demonstrated in phase III-trials. Indeed nab-pac...
Napabucasin (also known as BBI-608 or BBI608) is an investigational, oral agent hypothesized to inhibit multiple oncogenic pathways. In this article, we describe the design and rationale for the CanStem111P clinical trial, a multicenter, randomized, open-label, Phase III study designed to determine the efficacy and safety of combining napabucasin with nab-paclitaxel and gemcitabine for first-line treatment of patients with metastatic pancreatic adenocarcinoma (NCT02993731). Patients were randomized in a 1:1...
Poly (ADP-ribose) polymerase 1 (PARP1) is a nuclear enzyme that participates in the DNA repair of malignant cells, with various consequences on their survival. We have recently shown that PARP1 mRNA levels in the bone marrow of patients with myelodysplastic syndrome (MDS) are correlated to prognosis. To evaluate PARP1 as a biomarker of response to 5-azacytidine in patients with MDS, we measured PARP1 mRNA levels by a quantitative real-time PCR in diagnostic bone marrow samples of 77 patients with MDS treate...
The objectives of this study were to assess the feasibility of preoperative gemcitabine/nab-paclitaxel-based chemoradiation therapy (CRT) for patients with borderline resectable pancreatic cancer (BRPC), which consists of induction chemotherapy and subsequent CRT, and to determine the recommended dose (RD) of gemcitabine/nab-paclitaxel with concurrent radiation therapy in a phase I trial.
Population pharmacokinetics of carboplatin, etoposide and melphalan in children: A re-evaluation of paediatric dosing formulas for carboplatin in patients with normal or mild impairment of renal function.
Carboplatin is dosed by the glomerular filtration rate (GFR) to achieve target plasma area under the curve (AUC). The aims of this study were to investigate factors that influence the pharmacokinetics of carboplatin in children with high-risk neuroblastoma and to investigate whether target exposures for carboplatin were achieved using current treatment protocols.
Introduction Selumetinib (AZD6244, ARRY-142886) is a potent inhibitor of MEK1/2, thereby inhibiting phosphorylation of ERK2. We investigated the toxicity and the recommended phase II dose of the combination of selumetinib with two platinum based first line chemotherapy combinations in non-small cell lung cancer. Methods This was a phase I trial of escalating doses of selumetinib with carboplatin (AUC 6), paclitaxel (200 mg/m) (cohort 1) or pemetrexed (500 mg/m) and cisplatin (75 mg/m) (cohort 2) in patie...
PARP1 inhibitors alone or in combination with DNA damaging agents are promising clinical drugs in the treatment of cancer. However, there is a need to understand the molecular mechanisms of resistance to PARP1 inhibitors. Expression of HMGA2 in cancer is associated with poor prognosis for patients. Here, we investigated the novel relationship between HMGA2 and PARP1 in DNA damage-induced PARP1 activity. We used human triple negative breast cancer and fibrosarcoma cell lines to demonstrate that HMGA2 colocal...
Poly(ADP-ribose) polymerase 1 (PARP1) is both a first responder to DNA damage and a chromatin architectural protein. How PARP1 rapidly finds DNA damage sites in the context of a nucleus filled with undamaged DNA, to which it also binds, is an unresolved question. Here we show that PARP1 association with DNA is diffusion-limited, and release of PARP1 from DNA is promoted by binding of an additional DNA molecule that facilitates a 'monkey bar' mechanism, also known as intersegment transfer. The WGR-domain of ...
WT1 associated protein (WTAP), playing an important role in several malignancies owing to its complex function in transcriptional and post-transcriptional regulation, is an independent prognostic indicator for pancreatic cancer (PC). However, its specific role and underlying mechanism in PC remain unclear. In the present study, we found that WTAP could promote migration/invasion and suppress chemo-sensitivity to gemcitabine in PC. Further mechanical investigation revealed that WTAP could bind to and stabili...
Phase 1b/2 Randomized Study of MEDI-575 in Combination With Carboplatin Plus Paclitaxel Versus Carboplatin Plus Paclitaxel Alone in Adult Patients With Previously Untreated Advanced Non-Small-Cell Lung Cancer.
Platinum doublet chemotherapy has represented the standard of care in advanced non-small-cell lung cancer for decades. Targeting platelet-derived growth factor receptors (PDGFR) is a potential mechanism to improve the efficacy of first-line therapy. This randomized phase 1b/2 trial investigated the addition of the anti-PDGFRα monoclonal antibody MEDI-575 to first-line carboplatin/paclitaxel (CP) chemotherapy.
In the FOURIER trial, evolocumab, a proprotein convertase subtilisin-kexin type 9 inhibitor, reduced cardiovascular events in patients with atherosclerotic cardiovascular disease (ASCVD). We aimed to examine how closely patients in routine practice resemble the FOURIER trial participants and to assess the observed cardiovascular risks based on trial eligibility and underrepresentativeness.
Gemcitabine is the cornerstone of pancreatic cancer treatment. Although effective in most patients, development of tumor resistance to gemcitabine can critically limit its efficacy. The mechanisms responsible for this phenomenon remain elusive, but evidence suggests that ubiquitin-specific peptidases (USPs) may be key regulators in cancer chemo-resistance. The present study aimed to investigate the role of USP9X in gemcitabine resistance using in vitro pancreatic cell lines and a mouse xenograft model. We f...
Surgery remains the best curative treatment option for non-small cell lung cancer (NSCLC), but is of benefit only to patients with localized disease. A meta-analysis showed a significant beneficial effect of induction chemotherapy on survival, but there is still no clear evidence. This phase II study was conducted to establish whether induction chemotherapy with carboplatin (CBDCA) and paclitaxel (PTX) plus bevacizumab prior to surgery reduces the risk of progression.
In our previous randomised phase 2 study for patients with gemcitabine-refractory advanced pancreatic cancer, S-1 plus leucovorin improved progression-free survival compared with S-1 alone. Here, we evaluated the efficacy of TAS-118 (S-1 plus leucovorin) versus S-1 in overall survival (OS).
A randomized, controlled trial has begun to compare neoadjuvant chemotherapy using gemcitabine and S-1 with upfront surgery for patients planned resection of pancreatic cancer. Patients were enrolled after the diagnosis of resectable or borderline resectable by portal vein involvement pancreatic cancer with histological confirmation. They were randomly assigned to either neoadjuvant chemotherapy or upfront surgery. Adjuvant chemotherapy using S-1 was administered for 6 months to patients with curative resec...
The current trial assessed whether the addition of cisplatin and capecitabine to the nab-paclitaxel-gemcitabine backbone is feasible and active against borderline and locally advanced pancreatic adenocarcinoma (PDAC).
Poly (ADP-ribose) polymerase-1 (PARP1) is a major member of the PARP superfamily that is involved in DNA damage signalling and other important cellular processes. Here we report the development of a small molecule targeting PARP1 based on the PROTAC strategy. In the MDA-MB-231 cell line, the representative compound 3 can induce significant PARP1 cleavage and programmed cell death.
The poor prognosis of ovarian cancer (it is the leading cause of death from gynecological cancers) is mainly due to the acquisition of resistance to carboplatin. Among the possible resistance pathways, resistance to apoptosis and especially the overexpression of inhibitor of apoptosis proteins (IAP) cIAP1 and X-linked IAP (XIAP), have been implicated. DEBIO 1143, a SMAC (second mitochondria-derived activator of caspase) mimetic, belongs to a new class of targeted agents currently being evaluated in clinical...
More than 50% of all patients with advanced urothelial carcinoma cannot receive highly toxic cisplatin-based chemotherapy as the first-line treatment because of their unsatisfactory performance status and co-morbidities. Replacement of cisplatin with carboplatin does not produce a desired improvement with regard to efficacy. In addition, 20% of patients either are carboplatin-ineligible or discontinue this drug as well. This article is protected by copyright. All rights reserved.
One of the standard of care regimens for advanced pancreatic cancer is gemcitabine-based chemotherapy. The efficacy of gemcitabine is limited by dose-limiting hematologic toxicities especially neutropenia. Uncovering the variability of these toxicities attributed to germline DNA variation is of great importance.
Gemcitabine-based salvage therapy is considered an effective treatment for relapsed and refractory Non-Hodgkin's lymphoma (NHL). We analyzed the outcome of 41 consecutive NHL patients treated with gemcitabine-based regimens between January 2007 and October 2015. Twenty-eight males and 13 females (median age 66.4 years) were included. The median follow-up from gemcitabine initiation was 7.3 months. Thirty patients (73%) had B-cell, and eleven (27%) had T-cell, lymphoma. All patients received a median of 2 pr...
