Insights

Cancer drug development faces high attrition rates despite new agents. Innovations in "best-in-class" drugs show more industry value than novel "first-in-class" drugs, necessitating better early efficacy assessments.

Area of Science:

  • Oncology
  • Pharmaceutical Sciences
  • Clinical Trials

Background:

  • The last decade has seen significant growth in novel cancer drug candidates entering clinical evaluation.
  • High attrition rates persist in cancer drug development, from early trials to regulatory approval.
  • Industry value is increasingly derived from 'best-in-class' innovations rather than purely 'first-in-class' novel agents.

Purpose of the Study:

  • To address the high attrition rate in cancer drug development.
  • To explore novel methods for early assessment of drug efficacy and proof-of-principle.
  • To improve the success of new anti-cancer agents through better early evaluation.

Main Methods:

  • Review of recent trends in cancer drug development.
  • Analysis of industry value creation from different types of drug innovation.
  • Discussion of limitations of conventional anatomical imaging for assessing treatment response.
  • Exploration of the need for advanced methods for early efficacy assessment.

Main Results:

  • Cancer drug development expansion is coupled with a high failure rate.
  • Clinically validated 'best-in-class' innovations generate more industry value than 'first-in-class' drugs.
  • Conventional anatomical imaging may be inadequate for evaluating many new cancer agents and could contribute to attrition.

Conclusions:

  • There is a critical need for improved early assessment methods in cancer drug development.
  • Advanced techniques are required to demonstrate proof-of-principle and efficacy for novel cancer therapies.
  • Rethinking response assessment strategies is crucial to reduce the high attrition rates in oncology drug development.

Positron Emission Tomography

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body being...

Imaging Studies II: Positron Emission Tomography and Scintigraphy

Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
