Trifluridine-Tipiracil and Bevacizumab in Refractory Metastatic Colorectal Cancer.

Background: In a previous phase 3 trial, treatment with trifluridine-tipiracil (FTD-TPI) prolonged overall survival among patients with metastatic colorectal cancer. Preliminary data from single-group and randomized phase 2 trials suggest that treatment with FTD-TPI in addition to bevacizumab has the potential to extend survival.

Methods: We randomly assigned, in a 1:1 ratio, adult patients who had received no more than two previous chemotherapy regimens for the treatment of advanced colorectal cancer to receive FTD-TPI plus bevacizumab (combination group) or FTD-TPI alone (FTD-TPI group).

Trifluridine-tipiracil plus bevacizumab versus capecitabine plus bevacizumab as first-line treatment for patients with metastatic colorectal cancer ineligible for intensive therapy (SOLSTICE): a randomised, open-label phase 3 study.

Background: Trifluridine-tipiracil plus bevacizumab has shown efficacy in previous phase 2 studies including patients with unresectable metastatic colorectal cancer. We aimed to investigate first-line trifluridine-tipiracil plus bevacizumab versus capecitabine plus bevacizumab in patients with unresectable metastatic colorectal cancer ineligible for intensive treatment.

Methods: In this open-label, randomised, phase 3 study, we enrolled patients aged 18 years and older with histologically confirmed metastatic colorectal cancer, ineligible for full-dose doublet or triplet chemotherapy and curative resection across 25 countries and regions.

Trifluridine/tipiracil plus bevacizumab for third-line management of metastatic colorectal cancer: SUNLIGHT study design.

Trifluridine/tipiracil (FTD/TPI) is an orally active formulation of trifluridine, a thymidine-based nucleoside analog, and tipiracil hydrochloride, a thymidine phosphorylase inhibitor that increases the bioavailability of trifluridine. Preliminary studies of FTD/TPI plus bevacizumab have produced encouraging results in the treatment of refractory metastatic colorectal cancer. Here, we describe the design of the multinational Phase III SUNLIGHT, an open-label study of FTD/TPI plus bevacizumab as third-line treatment for patients with unresectable metastatic colorectal cancer.

Health-related quality of life associated with trifluridine/tipiracil in heavily pretreated metastatic gastric cancer: results from TAGS.

Background: In TAGS, an international, double-blind, phase 3 trial, trifluridine/tipiracil significantly improved overall survival and progression-free survival compared with placebo in heavily pretreated metastatic gastric cancer patients. This paper reports pre-specified quality of life (QoL) outcomes for TAGS.

Methods: Patients were randomized 2:1 to trifluridine/tipiracil (35 mg/m twice daily on days 1-5 and 8-12 of each 28-day cycle) plus best supportive care (BSC) or placebo plus BSC.

First-line trifluridine/tipiracil plus bevacizumab for unresectable metastatic colorectal cancer: SOLSTICE study design.

Trifluridine/tipiracil (TT) is an orally administered combination of the thymidine-based nucleoside analogue trifluridine and the thymidine phosphorylase inhibitor tipiracil hydrochloride, which increases the bioavailability of cytotoxic trifluridine. Encouraging antitumor activity of first-line TT + bevacizumab (TT-B) has been observed in a Phase II study in patients with unresectable metastatic colorectal cancer ineligible for combination oxaliplatin- or irinotecan-based therapy. Here, we describe the design of SOLSTICE (NCT03869892), an open-label, Phase III trial in unresectable metastatic colorectal cancer patients who are not candidates for, or do not require, intensive therapy.

Trifluridine/Tipiracil plus Oxaliplatin Improves PD-1 Blockade in Colorectal Cancer by Inducing Immunogenic Cell Death and Depleting Macrophages.

Trifluridine/tipiracil (FTD/TPI) is a new antimetabolite agent used to treat chemorefractory metastatic colorectal cancer. FTD/TPI induced immunogenic cell death (ICD) in the microsatellite-stable (MSS) CT26 mouse colon carcinoma cell line, as well as in various human MSS colorectal cancer cell lines (SW620, Caco-2, and Colo-320). The combination of FTD/TPI with oxaliplatin synergized to promote ICD.

Phase I dose-escalation of trifluridine/tipiracil in combination with oxaliplatin in patients with metastatic colorectal cancer.

Background And Objectives: Pre-clinical data have shown that combining trifluridine/tipiracil with oxaliplatin enhances anti-tumour activity compared with either monotherapy. A phase I dose-escalation study was conducted to determine the maximum tolerated dose (MTD), recommended dose (RD) for phase II and pharmacokinetic profile of this combination in patients with metastatic colorectal cancer (mCRC) who had progressed after at least 1 prior line of treatment.

Methods: Using a 3 + 3 design, patients received escalating trifluridine/tipiracil doses from 25, then 30 and to 35 mg/m twice daily, days 1-5, q14 days, together with a fixed dose of 85 mg/m of oxaliplatin day 1, q14 days.

Proxies of quality of life in metastatic colorectal cancer: analyses in the RECOURSE trial.

Background: In the pivotal phase III, randomised, double-blind, placebo-controlled RECOURSE study, treatment with trifluridine/tipiracil was well tolerated and associated with prolonged progression-free and overall survival in patients with metastatic colorectal cancer (mCRC). There was no formal analysis of quality of life (QoL) in RECOURSE. The aim of the present analysis was to assess proxies of QoL during the RECOURSE treatment period, in terms of adverse events (AEs) likely to affect QoL and Eastern Cooperative Oncology Group performance status (ECOG PS).

QTWiST analysis of the RECOURSE trial of trifluridine/tipiracil in metastatic colorectal cancer.

Purpose: A Quality-adjusted Time WIthout Symptoms of disease or Toxicity (QTWiST) analysis was carried out to assess quality-adjusted survival time in the RECOURSE trial of trifluridine/tipiracil versus placebo in pretreated metastatic colorectal cancer (mCRC).

Methods: Duration of overall survival in the RECOURSE trial (n=798 patients) was partitioned into three discrete health states: toxicity (TOX), time without symptoms or toxicity (TWIST) and relapse (REL). TOX was defined as time spent with grade 3 or 4 treatment-related adverse events (AEs) after randomisation and before progression or censoring.

Phase I study of afatinib combined with nintedanib in patients with advanced solid tumours.

Background: This Phase I study evaluated continuous- and intermittent-dosing (every other week) of afatinib plus nintedanib in patients with advanced solid tumours.

Methods: In the dose-escalation phase (n=45), maximum tolerated doses (MTDs) were determined for continuous/intermittent afatinib 10, 20, 30 or 40 mg once daily plus continuous nintedanib 150 or 200 mg twice daily. Secondary objectives included safety and efficacy.

PM00104 (Zalypsis®) is a new synthetic alkaloid with potent cytotoxic activity against tumor cell lines. This phase I clinical trial determined the maximal tolerated dose (MTD) and recommended dose (RD) for phase II trials of PM00104 administered as a 1-hour intravenous (i.v.

Phase II trial of weekly alternating sequential BIBF 1120 and afatinib for advanced colorectal cancer.

Aim: The feasibility of an alternating regimen of BIBF 1120, a potent, oral, triple angiokinase inhibitor, and afatinib (BIBW 2992), a potent ErbB family blocker, was explored in patients with advanced pretreated colorectal cancer (CRC).

Patients And Methods: Patients received repeated courses of alternating 7-day treatment periods, first with BIBF 1120 250 mg twice daily and then afatinib 50 mg once daily. The primary endpoint was the objective response rate; the incidence/severity of adverse events (AEs) and pharmacokinetics (PK) were determined.

Platinum-based chemotherapy plus cetuximab in head and neck cancer.

Background: Cetuximab is effective in platinum-resistant recurrent or metastatic squamous-cell carcinoma of the head and neck. We investigated the efficacy of cetuximab plus platinum-based chemotherapy as first-line treatment in patients with recurrent or metastatic squamous-cell carcinoma of the head and neck.

Methods: We randomly assigned 220 of 442 eligible patients with untreated recurrent or metastatic squamous-cell carcinoma of the head and neck to receive cisplatin (at a dose of 100 mg per square meter of body-surface area on day 1) or carboplatin (at an area under the curve of 5 mg per milliliter per minute, as a 1-hour intravenous infusion on day 1) plus fluorouracil (at a dose of 1000 mg per square meter per day for 4 days) every 3 weeks for a maximum of 6 cycles and 222 patients to receive the same chemotherapy plus cetuximab (at a dose of 400 mg per square meter initially, as a 2-hour intravenous infusion, then 250 mg per square meter, as a 1-hour intravenous infusion per week) for a maximum of 6 cycles.

Overview of the efficacy of cetuximab in recurrent and/or metastatic squamous cell carcinoma of the head and neck in patients who previously failed platinum-based therapies.

Background: The epidermal growth factor receptor (EGFR) inhibitor cetuximab is active in recurrent and/or metastatic squamous cell carcinoma of the head and neck (SCCHN). The activity of cetuximab was compared with that of commonly used treatments in this setting.

Methods: All patients had recurrent and/or metastatic SCCHN and had progressed on cisplatin- or carboplatin-based chemotherapy.

Quality of life in head and neck cancer patients after treatment with high-dose radiotherapy alone or in combination with cetuximab.

Purpose: In this randomized, phase III study, quality of life (QoL) was assessed in patients with locoregionally advanced squamous cell carcinoma of the head and neck (SCCHN) after high-dose radiotherapy alone or in combination with cetuximab.

Patients And Methods: Patients with stage III or IV nonmetastatic and measurable squamous cell carcinoma of the oropharynx, hypopharynx, or larynx were eligible. QoL was assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30) and EORTC QLQ Head and Neck Cancer-Specific Module at baseline, week 4, and at months 4, 8, and 12 postbaseline.

Purpose: This was an open, randomized, multicenter, phase I/II study to investigate the safety and tolerability of cetuximab in the first-line treatment of recurrent/metastatic squamous cell carcinoma of the head and neck (SCCHN).

Patients And Methods: Treatment comprised cetuximab (initial dose 400 mg/m2 with subsequent weekly doses of 250 mg/m2) in combination with 3-week cycles of either cisplatin (100 mg/m2) or carboplatin (area under the curve, 5), each in combination with a 5-day infusion of fluorouracil (FU) at escalating doses of 600, 800, and 1,000 mg/m2/d. The study was divided into two phases: A, the first two cycles (6 weeks) focusing on the safety and tolerability of combination therapy; and B, the remaining time for those benefiting from therapy until disease progression or intolerable toxicity.

Radiotherapy plus cetuximab for squamous-cell carcinoma of the head and neck.

Background: We conducted a multinational, randomized study to compare radiotherapy alone with radiotherapy plus cetuximab, a monoclonal antibody against the epidermal growth factor receptor, in the treatment of locoregionally advanced squamous-cell carcinoma of the head and neck.

Methods: Patients with locoregionally advanced head and neck cancer were randomly assigned to treatment with high-dose radiotherapy alone (213 patients) or high-dose radiotherapy plus weekly cetuximab (211 patients) at an initial dose of 400 mg per square meter of body-surface area, followed by 250 mg per square meter weekly for the duration of radiotherapy. The primary end point was the duration of control of locoregional disease; secondary end points were overall survival, progression-free survival, the response rate, and safety.
