BACKGROUND The nuclear transcription factor c-Jun is preferentially expressed in basal-cell carcinoma. Dz13 is a deoxyribozyme that targets JUN messenger RNA and has inhibited the growth of a range of tumours in mice. We did a phase 1 study to assess safety and tolerability in human beings. METHODS Adults with nodular basal-cell carcinoma were recruited(More)
Immune responses are tightly regulated via signaling through numerous co-stimulatory and co-inhibitory molecules. Exploitation of these immune checkpoint pathways is one of the mechanisms by which tumors evade and/or escape the immune system. A growing understanding of the biology of immune checkpoints and tumor immunology has led to the development of(More)
The last 12 months have seen the beginning of a new era in the treatment options available for patients with metastatic cutaneous melanoma, a disease previously characterised by its poor prognosis and limited treatment options. Two mechanistically diverse agents have now demonstrated an overall survival benefit in different patient subgroups and further(More)
Two multicenter, single-arm, single-infusion, open-label studies were conducted to evaluate the effect of ketoconazole (a strong CYP3A inhibitor) or rifampin (a strong CYP3A inducer) daily for 5 days on the pharmacokinetics (PK) and safety of romidepsin (8 mg/m(2) intravenous 4-hour infusion for the ketoconazole study or a 14 mg/m(2) intravenous 4-hour(More)
The treatment of advanced melanoma has been revolutionised in recent years with the advent of a range of new therapies. BRAF inhibitors, such as vemurafenib, have demonstrated improvements in the overall survival of patients with advanced melanoma that harbour a BRAF V600 mutation. Alongside these targeted therapies, novel immune-checkpoint inhibitors, such(More)
Introduction. A survey was sent to referring oncologists (ROs) to explore the reasons behind their referral patterns and perceptions of Phase I studies before and after being provided with outcome data from advanced colorectal cancer (ACRC) patients who participated in Phase I trials at the Royal Marsden Hospital (RMH). Results. The response rate was 32/50(More)
The Personalized Medicine approach in oncology is a direct result of an improved understanding of complex tumor biology and advances in diagnostic technologies. In recent years, there has been an increased demand for archival and fresh tumor analysis in early clinical trials to foster proof-of-concept biomarker development, to understand resistance(More)
INTRODUCTION During early clinical testing of a new medication, it is critical to understand and characterise patient tolerability. However, in early clinical studies, it is difficult for patients to contribute directly to the sponsors' understanding of a new compound. Patient reported opinions about clinical tolerability (PROACT) provides a new, simple and(More)

PURPOSE TAS-102 is a novel oral agent combining the antineoplastic thymidine-based nucleoside analogue, trifluridine, and the thymidine phosphorylase inhibitor, tipiracil (molar ratio 1:0.5). TAS-102 has shown good activity in refractory metastatic colorectal cancer with acceptable safety. No QT prolongation was seen in clinical studies. This study aimed to(More)
