Chronic Pain – Special Topics – Special Topics: How will Anti-NGF Therapies Disrupt Existing Pain Treatment Algorithms? (US)

The most highly anticipated analgesic drugs in late-phase development belong to the anti-nerve growth factor (NGF) class: Pfizer / Eli Lilly’s tanezumab and Regeneron / Teva / Mitsubishi Tanabe’s fasinumab. As the first injectable biologics expected to launch in the crowded and highly generic oral chronic pain market, these drugs have the potential to disrupt the current later-line treatment algorithm of chronic pain patients. Despite demonstrations of impressive efficacy results in clinical trials, lingering concerns about the safety of this class may constrain prescribing. However, the need for less-addictive yet potent analgesics for chronic pain patients may lead physicians to overcome such concerns to provide robust analgesia to chronic pain patients without chronic use of opioid analgesics. We explore attitudes toward anti-NGF drugs and the potential disruption of treatment paradigms with the anticipated launch of these drugs.


  • How do physicians plan to prescribe the anti-NGF drugs? What prescription therapies or surgical treatments will be impacted by the availability of the anti-NGF drugs?
  • How have clinical trial data affected physicians’ attitudes toward the anti-NGF drugs’ safety profiles in chronic pain patients? What are the top reasons some physicians would refrain from prescribing the anti-NGF drugs?
  • To what extent do physicians differentiate between tanezumab and fasinumab, and what factors influence their preferences?
