Prospective, Observational Study To Assess The Safety Of Rituximab In Combination With Chemotherapy In Patients With Previously-Untreated Or Relapsed…

2013

Abstract Aim and Background The efficacy and safety of rituximab plus chemo (R+chemo) for first-line and relapsed B-CLL patients(pts) have been widely investigated in clinical trials and large patient cohorts, but much less is known about whether such regimens can be effectively and safely administered to unselected pts in the community setting to reflect the routine care of B-CLL pts. Therefore, this observational study was designed to characterize the type, severity and frequency of all adverse events occurring on-treatment and in the year following rituximab infusion. A secondary objective was to assess response rate (CR/nPR/PR), duration of response, disease-free survival, overall survi…

Pimasertib Versus Dacarbazine in Patients With Unresectable NRAS-Mutated Cutaneous Melanoma: Phase II, Randomized, Controlled Trial with Crossover

2020

This study investigated the efficacy and safety of pimasertib (MEK1/MEK2 inhibitor) versus dacarbazine (DTIC) in patients with untreated NRAS-mutated melanoma. Phase II, multicenter, open-label trial. Patients with unresectable, stage IIIc/IVM1 NRAS-mutated cutaneous melanoma were randomized 2:1 to pimasertib (60 mg

Epidemiology and characteristics of febrile neutropenia in oncology patients from Spanish tertiary care hospitals: PINNACLE study.

2015

Febrile neutropenia (FN) is one of the most common adverse events associated with myelosuppressive chemotherapy for cancer treatment. The objective of this study was to describe the incidence of hospitalization due to FN in Spanish tertiary care hospitals (PINNACLE study). This epidemiological, retrospective, multicenter, nationwide study involved 119 patients from oncology units of 10 Spanish tertiary care hospitals who were admitted for FN. The primary endpoint was to assess the epidemiology and characteristics of FN. The incidence of admissions due to FN in oncology patients was 2.0% (interquartile range [IQR], 1.6–3.0). In terms of fever and absolute neutrophil count (ANC), 37.0% of the…

Abstract PD1-02: A phase I/Ib study evaluating GDC-0077 + palbociclib (palbo) + fulvestrant in patients (pts) with PIK3CA-mutant (mut), hormone recep…

2021

Abstract Background GDC-0077 is a PI3Kα-selective inhibitor and mutant PI3Kα degrader that demonstrates antitumor activity in PIK3CAmut BC xenograft models. A phase I/Ib study of GDC-0077 alone and combined with endocrine therapy ± the CDK4/6 inhibitor (i) palbo is ongoing (NCT03006172). Data from GDC-0077 + palbo + fulvestrant in pts with PIK3CAmut, HR+/HER2- mBC are presented herein. Methods Safety (NCI-CTCAE v4), pharmacokinetics (PK), and preliminary antitumor activity (clinical benefit rate [CBR]: RECIST v1.1 stable disease for ≥ 24 weeks, partial response [PR], or complete response) of 9 mg oral once daily GDC-0077 + 125 mg palbo 21/28 days + 500 mg intramuscular fulvestrant on day 1 …

Abstract PS11-11: Targeted safety events from a phase I/Ib study evaluating GDC-0077 alone and in combination with endocrine therapy (ET) ± palbocicl…

2021

Abstract Background Activating mutations in PIK3CA, encoding the p110α subunit of phosphatidylinositol 3-kinase (PI3K) occur in ~40% of HR+/HER2- BCs. GDC-0077, a PI3Kα-selective inhibitor and mutant PI3Kα degrader, is being developed as an anticancer agent. A phase I/Ib study of GDC-0077 alone and combined with other therapies is ongoing in pts with locally advanced or metastatic PIK3CAmut, HR+/HER2- mBC (NCT03006172). Targeted safety events are presented here. Methods Safety was assessed via NCI-CTCAE v4 for GDC-0077 administered alone (Arm A), with letrozole and palbo (Arm B), with letrozole (Arm C), with fulvestrant (Arm D), or with fulvestrant and palbo (Arm E, plus metformin in Arm F …

IntroductionImmune checkpoint inhibitors (ICI) are increasingly being used to treat numerous cancer types. Together with improved recognition of toxicities, this has led to more frequent identification of rare immune-related adverse events (irAE), for which specific treatment strategies are needed. Neutropenia is a rare hematological irAE that has a potential for a high mortality rate because of its associated risk of sepsis. Prompt recognition and timely treatment of this life-threatening irAE are therefore critical to the outcome of patients with immune-related neutropenia.MethodsThis multicenter international retrospective study was conducted at 17 melanoma centers to evaluate the clinic…

ABCL-366: Mosunetuzumab (Mosun) Monotherapy for Elderly/Unfit Patients with First-Line Diffuse Large B-Cell Lymphoma (DLBCL) Continues to Show Promis…

2021

Context Mosun, a full-length, humanized, IgG1 CD20×CD3 bispecific antibody, demonstrated efficacy/safety in relapsed/refractory DLBCL (NCT02500407; Schuster, et al. ASH 2019). The phase I/II multicenter GO40554 (NCT03677154) study showed similar results for elderly/unfit patients with first-line DLBCL intolerant of full-dose chemoimmunotherapy (CIT) (Olszewski, et al. ASH 2020). Objective To describe updated GO40554 study data. Methods Two safety-evaluation cohorts were assessed (Mosun 13.5 mg and 30 mg), then a 30 mg expansion phase. Patients were aged ≥80 years; 60–79 years with impairment in ≥1 activity of daily living (ADL); instrumental ADL; or impaired cardiac, renal, or liver functio…

Abstract LB-146: A phase II randomized placebo-controlled study of AZD8931, an inhibitor of EGFR, HER2, and HER3 signaling, plus paclitaxel (P) vs P …

2013

Abstract Background: AZD8931 is an oral, equipotent inhibitor of EGFR, HER2, and HER3 signaling. Preclinical evidence indicates that AZD8931 may be particularly potent when HER signaling is ligand driven, which is thought to be the signaling mechanism that is more prevalent in low HER2-expressing BC. Methods: In this double-blind multicenter phase II study, women with low HER2- expressing locally advanced or metastatic BC (ineligible by HER2 status for either trastuzumab or lapatinib) were randomized 1:1 to AZD8931 40mg bid + P (90mg/m2; d1, 8 and 15, q4 weeks) or matched placebo + P (NCT00900627). The primary objective was prolonged progression-free survival (PFS; assessed by RECIST v1.1);…

Ofatumumab Combined With Fludarabine and Cyclophosphamide (O-FC) Shows High Activity in Patients With Previously Untreated Chronic Lymphocytic Leukem…

2010

Abstract 207 Introduction: Chemoimmunotherapy regimens have become the treatment standard for patients with CLL. Ofatumumab is a human monoclonal antibody that targets a unique small-loop epitope on CD20 and elicits rapid and efficient in vitro complement-dependent cytotoxicity, as well as antibody-dependent cellular cytotoxicity. Recent studies demonstrated single-agent ofatumumab activity, with high overall response rates (ORR) in patients with refractory CLL. We conducted an international, randomized, parallel group, Phase II trial with two doses of ofatumumab combined with fludarabine and cyclophosphamide (FC) in previously untreated patients with CLL to evaluate the efficacy and tolera…

Evaluation of ABC gene polymorphisms on the pharmacokinetics and pharmacodynamics of capecitabine in colorectal patients: Implications for dosing rec…

2020

Aims The aims are to develop a population pharmacokinetic model of capecitabine (CAP) and its main metabolites after the oral administration of CAP in colorectal cancer patients with different polymorphisms of the ATP-binding cassette (ABC) gene and a population pharmacokinetic/pharmacodynamic model capable of accounting for the neutropenic effects, and to optimize the dosing strategy based on the polymorphisms of the ABC gene and/or the administration regimen as a single agent or in combination. Methods Forty-eight patients diagnosed with colorectal cancer were included, with 432 plasma levels of CAP, 5'-desoxi-5-fluorouridine (5'-DFUR) and 5-fluorouracil (5-FU), and 370 neutrophil observa…
