Abstract

Insights

Dovitinib did not improve progression-free survival in recurrent glioblastoma (GBM) patients, regardless of prior anti-angiogenic therapy. The study found no significant efficacy in prolonging PFS for GBM patients treated with dovitinib.

Area of Science:

  • Oncology
  • Pharmacology

Background:

  • Dovitinib is an oral inhibitor targeting FGFR and VEGFR.
  • It was investigated as a potential treatment for recurrent or progressive glioblastoma (GBM).

Purpose of the Study:

  • To evaluate the efficacy of dovitinib in patients with recurrent GBM.
  • To compare outcomes in anti-angiogenic-naïve patients versus those with prior anti-angiogenic therapy.

Main Methods:

  • An open-label, two-arm phase II study was conducted.
  • Arm 1: anti-angiogenic-naïve recurrent GBM patients.
  • Arm 2: recurrent GBM patients progressed on prior anti-angiogenic therapy.

Main Results:

  • Six-month progression-free survival (PFS-6) was 12% in Arm 1 and 0% in Arm 2.
  • Time to progression (TTP) was similar between arms (median 1.8 months vs. 0.7-1.8 months).
  • High rates of grade 3 and 4 toxicities were observed (67% and 15%, respectively).

Conclusions:

  • Dovitinib demonstrated no efficacy in prolonging PFS for recurrent GBM patients.
  • Efficacy was not observed irrespective of prior anti-angiogenic treatment, including bevacizumab.

Phase Diagrams

A phase diagram combines plots of pressure versus temperature for the liquid-gas, solid-liquid, and solid-gas phase-transition equilibria of a substance. These diagrams indicate the physical states that exist under specific conditions of pressure and temperature and also provide the pressure dependence of the phase-transition temperatures (melting points, sublimation points, boiling points). Regions or areas labeled solid, liquid, and gas represent single phases, while lines or curves represent...

Phase Transitions02:31

Phase Transitions

Whether solid, liquid, or gas, a substance's state depends on the order and arrangement of its particles (atoms, molecules, or ions). Particles in the solid pack closely together, generally in a pattern. The particles vibrate about their fixed positions but do not move or squeeze past their neighbors. In liquids, although the particles are closely spaced, they are randomly arranged. The position of the particles are not fixed—that is, they are free to move past their neighbors to...

Inductance: Single-Phase And Three-Phase Line

Understanding the inductance of transmission lines is crucial for efficient design and operation in electrical power systems. This discussion delves into the inductance characteristics of single-phase two-wire and three-phase three-wire transmission lines with equal phase spacing.
Single-Phase Two-Wire Line:
A single-phase line consists of two solid cylindrical conductors, denoted as x and y. Each conductor carries phasor currents ix and iy, respectively. Given that the sum of these currents is...

Capacitance: Single-Phase And Three-Phase Line

In electrical power systems, understanding the capacitance of transmission lines is fundamental for efficient operation.
Single-Phase Lines
Consider a single-phase, two-wire transmission line with equal phase spacing energized by a voltage source. One conductor carries a uniform positive charge, while the other carries an equal negative charge. The capacitance C of the line can be derived from the voltage V between the conductors. For a one-meter section of the line, the capacitance is given...

Phase Changes

Phase transitions play an important theoretical and practical role in the study of heat flow. In melting or fusion, a solid turns into a liquid; the opposite process is freezing. In evaporation, a liquid turns into a gas; the opposite process is condensation.
A substance melts or freezes at a temperature called its melting point and boils or condenses at its boiling point. These temperatures depend on pressure. High pressure favors the denser form of the substance, so typically, high pressure...

Phase-lead and Phase-lag Controllers01:22

Phase-lead and Phase-lag Controllers

Understanding the working function of different types of controllers can be illustrated with practical analogies, such as adjusting a stereo's volume equalizer. Cranking up the bass involves a phase-lead controller, which functions as a high-pass filter, while increasing the treble uses a phase-lag controller, which acts as a low-pass filter. PD controllers, similar to high-pass filters, enhance the system's response to high-frequency components. PI controllers, akin to low-pass...
