Identification of a genetic signature enriching for response to ibrutinib in relapsed/refractory follicular lymphoma in the DAWN phase 2 trial.
2021
Abstract Background The single‐arm DAWN trial (NCT01779791) of ibrutinib monotherapy in patients with relapsed/refractory follicular lymphoma (FL) showed an overall response rate (ORR) of 20.9% and a median response duration of 19.4 months. This biomarker analysis of the DAWN dataset sought to determine genetic classifiers for prediction of response to ibrutinib treatment. Methods Whole exome sequencing was performed on baseline tumor samples. Potential germline variants were excluded; a custom set of 1216 cancer‐related genes was examined. Responder‐ versus nonresponder‐associated variants were identified using Fisher's exact test. Classifiers with increasing numbers of genes were created …
Safety and efficacy of anti-PD-1 inhibitor ABBV-181 in lung and head and neck carcinoma
2019
Abstract Background ABBV-181 is a humanized anti-PD1 monoclonal antibody; dose finding and early safety, PK and pharmacodynamic data have been reported (ESMO18). This report summarizes data from the head and neck squamous cell carcinoma (HNSCC) and non-small cell lung cancer (NSCLC) expansion cohorts in the Ph1 FIH study (NCT03000257). Methods Patients (pts) with previously treated, advanced HNSCC and NSCLC received ABBV-181 IV, 250 mg Q2W or 500 mg Q4W to progression. Response was assessed by RECIST v1.1 and iRECIST. Results As of April 2019, 81 pts were dosed. Table . 1288P n (%) HNSCC n = 41 NSCLC n = 40 Median days on treatment, range 72, 1–407 71, 1–421 Dose: 250 mg/500 mg 31/10 19/21 …
Vinblastine and interferon-alpha-2a regimen in the treatment of metastatic renal cell carcinoma.
1990
Thirteen patients with histologically proven advanced and/or metastatic renal cell carcinoma (RCC) were treated with vinblastine (Velbe, Eli Lilly, Sesto Fiorentino, Italy) and interferon-alpha-2a (Roferon-A, Roche, Milan). Eleven out of 13 patients were evaluable. Eighteen percent of patients had partial response, 46 % stable disease (SD), and 36 % progressive disease (PD). The mean survival of responders was 228+ days, whereas the patients showing SD and PD had a mean survival of 154+ and 107+ days respectively. Toxicity, including influenza-like syndrome, fever, neurological and gastrointestinal side effects, was generally mild. However, medication with paracetamol was required in 82 % …
Role of Densitometric Criteria in Evaluation of Effectiveness of Antiangiogenic Therapies in Metastatic Colorectal Cancer: An Italian Clinical Experi…
2017
Background/Aim: To evaluate the role of densitometric criterion using the Choi Criteria in the assessment of the response to antiangiogenic treatments of metastatic colorectal cancer (mCRC) compared to the RECIST criteria. Patients and Methods: Fifty-four patients (mean age=50.6 years ) affected by advanced colorectal cancer and with hepatic and possibly peritoneal and pulmonary metastases, that can be treated with bevacizumab, were prospectively evaluated by computerized tomography (CT) scan. Metastases were also evaluated by CT in onedimensional form according to RECIST. Results: Results show that in 58% of analyzed cases, stable disease according to RECIST coincided with stable disease a…
Ibrutinib As Treatment for Chemoimmunotherapy-Resistant Patients with Follicular Lymphoma: First Results from the Open-Label, Multicenter, Phase 2 DA…
2016
Abstract Background: While first line therapy for FL with chemotherapy or chemoimmunotherapy produces durable responses, most patients (pts) with FL eventually relapse. Those who become resistant to chemoimmunotherapy have limited treatment options. Ibrutinib, an inhibitor of BTK (Bruton's tyrosine kinase) and ITK (interleukin-2-inducible T-cell kinase), has demonstrated robust clinical activity in various B-cell non-Hodgkin lymphomas. Previous Phase 1 and 2 studies have shown promising results with single-agent ibrutinib in pts with relapsed or refractory FL (Bartlett NL. Blood. 2014; 800 & Fowler N. Blood. 2015; 2706). The aim of the DAWN study was to provide additional efficacy and s…
A study on spectral optimisation in partial response CPM signals
1995
An optimisation technique for the minimisation of the effective bandwidth in partial response CPM signals is described. The minimum Euclidean distance is used as optimisation constraint because the bit error probability is a function of this parameter for high values of signal to noise ratio. The procedure has been implemented for a correlation length corresponding to two signalling intervals. The optimisation problem leads to a system of two nonlinear differential equations for the pulse shape, together with some boundary conditions. Numerical solution of the differential equations has been performed; initial conditions have been adjusted, to satisfy the boundary conditions using an iterat…
Cisplatinum in combination with 5-fluorouracil and citrovorum factor in the treatment of advanced colorectal carcinoma.
1992
A phase II trial of citrovorum factor, 500 mg/m2/week, plus 5-fluorouracil, 400 mg/m2/week on day 1, and cisplatin, 20 mg/m2/week on day 2, was carried out in a group of 40 patients with metastatic colorectal carcinoma. A partial response with a mean duration of 8.4+ months was achieved in 24% of patients, a minimal response with a mean duration of 5.4 months was obtained in 6% of patients, and a stabilization of 6.2 months was achieved in 41%. Ten patients (29%) progressed. A 38% partial response rate was seen in patients with advanced rectal carcinoma, whereas no response was obtained in patients with colon cancer. Interestingly, 5 partial responses were seen in 12 patients pretreated wit…
Cost effectiveness of boceprevir or telaprevir for previously treated patients with genotype 1 chronic hepatitis C.
2013
Background & Aims Randomised controlled trials (RCTs) show that triple therapy (TT) with peginterferon alfa, ribavirin, and boceprevir (BOC) or telaprevir (TVR) is more effective than peginterferon-ribavirin dual therapy (DT) in the treatment of genotype 1 (G1) chronic hepatitis C (CHC) patients with previous relapse (RR), partial response (PAR), and null-response (NR). We assess the cost-effectiveness of TT compared to no therapy in the treatment of patients previously treated with G1 CHC. Methods The available published literature provided the data source. The target population was made up of previously treated Caucasian patients with G1 CHC and these were evaluated over a lifetime horizo…
