Notch pathway inhibition with LY3039478 in soft tissue sarcoma and gastrointestinal stromal tumours.

Background: LY3039478 is an orally bioavailable selective Notch inhibitor. This phase 1a/b trial evaluated the safety, pharmacokinetics and antitumour activity of LY3039478 in patients with soft tissue sarcoma (STS) and gastrointestinal stromal tumour (GIST).

Methods: This multipart, phase 1 trial enrolled patients with refractory advanced/metastatic STS and GIST, measurable disease, Eastern Cooperative Oncology Group ≤1 and baseline tumour tissue.

A first-in-human phase I trial of LY2780301, a dual p70 S6 kinase and Akt Inhibitor, in patients with advanced or metastatic cancer.

The primary objective of this phase I study of LY2780301, a dual p70 S6 kinase and Akt inhibitor, was to determine the recommended phase II dose as a single agent in patients with advanced cancer. Secondary objectives included safety, pharmacokinetic, and pharmacodynamic analyses, and co-clinical analyses in Avatar models. Eligible patients received total daily doses of LY2780301 100-500 mg, given orally as a single dose or divided into 2 doses for 28-day cycles.

Preclinical analyses and phase I evaluation of LY2603618 administered in combination with pemetrexed and cisplatin in patients with advanced cancer.

LY2603618 is an inhibitor of checkpoint kinase 1 (CHK1), an important regulator of the DNA damage checkpoints. Preclinical experiments analyzed NCI-H2122 and NCI-H441 NSCLC cell lines and in vitro/in vivo models treated with pemetrexed and LY2603618 to provide rationale for evaluating this combination in a clinical setting. Combination treatment of LY2603618 with pemetrexed arrested DNA synthesis following initiation of S-phase in cells.

Phase-I-study of four different schedules of pemetrexed, gemcitabine and cisplatin in patients with locally advanced or metastatic solid tumours.

This non-randomised Phase-I-study determined recommended dose (RD) and dose-limiting toxicities (DLTs) of four different schedules combining pemetrexed (P), gemcitabine (G) and cisplatin (C). Patients 18 years with locally advanced/metastatic cancer were enrolled. Doses were escalated for one 21-d (q3w; PGC d1, G d8) and three 28-d schedules (q4wA: PG d1, GC d15; q4wB: GC d1, PC d15; q4wC: PGC d1+15).

Reduction of HLA-DR+ lymphocytes after treatment with enzastaurin in patients with metastatic thyroid cancer.

Background: Cytotoxic anti-tumor agents like methotrexate or cyclophosphamide have been used in the treatment of autoimmune diseases although the exact mechanism of their immunomodulatory function is unclear. By contrast, molecularly targeted anti-tumor agents, such as the serine/threonine kinase inhibitor enzastaurin, have not been evaluated for treatments other than cancer.

Methods: Blood was sampled from patients with metastatic thyroid cancer treated with enzastaurin followed by the combination treatment of enzastaurin and the anti-folate pemetrexed.

Prognostic significance of RASSF1A promoter methylation on survival of non-small cell lung cancer patients treated with gemcitabine.

The epigenetic inactivation of genes plays an important role in lung cancer. We have investigated the methylation status of the promoter region of seven genes (APC1A, DAPK, FHIT, p14(ARF), p16(INK4a), RARbeta, RASSF1A) in serum DNA of NSCLC patients. The objective of our study was to reveal the influence of such alterations on overall survival.

Promoter methylation of RASSF1A, RARbeta and DAPK predict poor prognosis of patients with malignant mesothelioma.

Hypermethylation occurs frequently in neoplastic cells and affects tumorigenesis. Malignant mesothelioma is an aggressive cancer developing in the thoracic cavity and patients have a rather bad prognosis. Our goal was to determine epigenetic alterations of a series of genes and to analyse the potential correlation of such changes with overall survival.
