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.

First-in-human study of LY3039478, an oral Notch signaling inhibitor in advanced or metastatic cancer.

Background: Deregulated Notch signaling due to mutation or overexpression of ligands and/or receptors is implicated in various human malignancies. γ-Secretase inhibitors inhibit Notch signaling by preventing cleavage of transmembrane domain of Notch protein. LY3039478 is a novel, potent Notch inhibitor decreases Notch signaling and its downstream biologic effects.

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).
