A novel drug specific mRNA biomarker predictor for selection of patients responding to dovitinib treatment of advanced renal cell carcinoma and other solid tumors.

Purpose: Dovitinib is a receptor tyrosine kinase inhibitor of VEGFR1-3, PDGFR, FGFR1/3, c-KIT, FLT3 and topoisomerase 1 and 2. The drug response predictor (DRP) biomarker algorithm or DRP-Dovitinib is being developed as a companion diagnostic to dovitinib and was applied retrospectively.

Patients And Methods: Archival tumor samples were obtained from consenting patients in a phase 3 trial comparing dovitinib to sorafenib in renal cell carcinoma patients and the DRP-Dovitinib was applied.

First-in-human study of the PARP/tankyrase inhibitor E7449 in patients with advanced solid tumours and evaluation of a novel drug-response predictor.

Background: This phase 1 study examined the safety, maximum-tolerated dose (MTD) and antitumour activity of E7449, a novel PARP 1/2 and tankyrase 1/2 inhibitor.

Methods: E7449 was orally administered once daily in 28-day cycles to patients with advanced solid tumours (50-800-mg doses). Archival tumour samples from consenting patients were evaluated for the expression of 414 genes in a biomarker panel (2X-121 drug-response predictor [DRP]) found to be predictive of the response to E7449 in cell lines.

New contraceptive patch wearability assessed by investigators and participants in a randomized phase 3 study.

Objective: To evaluate skin irritation and patch adhesiveness of a new weekly low-dose levonorgestrel (LNG) and ethinyl estradiol (EE) contraceptive patch (LNG/EE patch).

Study Design: This analysis was part of an open-label, parallel-group, multicenter, phase 3 study that randomized healthy women to the LNG/EE patch (one patch weekly for three consecutive weeks, followed by a patch-free week for 13 cycles) or to an oral contraceptive for six cycles followed by seven LNG/EE patch cycles. Participants selected patch application sites of abdomen, buttock or upper torso.

Self-reported and verified compliance in a phase 3 clinical trial of a novel low-dose contraceptive patch and pill.

Objective: Pregnancy rates in US contraceptive clinical trials are increasing due to decreased treatment compliance. This study compared compliance with a new low-dose levonorgestrel (LNG) and ethinyl estradiol (EE) contraceptive patch (CP, Twirla™) with that of a low-dose combination oral contraceptive (COC) in a demographically diverse population.

Study Design: This analysis was part of an open-label, parallel-group, multicenter phase 3 study that randomized healthy sexually active women (17-40years) to 13cycles of LNG/EE CP or 6cycles of COC, then 7cycles of LNG/EE CP.

Safety and tolerability of a new low-dose contraceptive patch in obese and nonobese women.

Objective: The safety and tolerability of a new low-dose levonorgestrel/ethinyl estradiol (LNG/EE) contraceptive patch was compared with 2 combination oral contraceptives in 2 clinical studies in which approximately 30% of enrolled participants were obese.

Study Design: Two phase 3, open-label, randomized, parallel-group, multicenter trials compared the LNG/EE contraceptive patch (n = 1579) with combination oral contraceptives (n = 581) in healthy women 17-40 years of age. Combination oral contraceptives were LNG 100 μg per EE 20 μg (combination oral contraceptive 20; n = 375) or LNG 150 μg per EE 30 μg (combination oral contraceptive 30; n = 206).
