Areas of Opportunity for Oral Ultra Long-acting Dosage Forms

Existing Non-Proprietary Agents Provide patient-centric options for superior pharmacology and adherence for existing small molecule drugs. Especially for medications with:
  • short half-lives

  • narrow GI absorption windows

  • narrow therapeutic indices

and diseases where:
  • adherence is closely related to product performance, or

  • where dose reduction/ reduced dosing frequency would improve patient outcomes significantly

Combination Products Where multiple oral drugs can be combined in a long-acting formulation:
  • medications for common comorbid conditions

  • patients with diseases requiring polypharmacy

Targeted or Non-systemic Delivery Conditions where targeted GI delivery improves bioavailability or avoids systemic drug exposure:
  • local GI Delivery with controlled targeting to upper and/or lower portions of the GI tract

  • enhanced safety profile by providing locally acting and/or rapidly metabolized drugs where systemic exposure is not required

Point of Care Administration Regimens that achieve a full treatment course in a single, long-acting dose:
  • applications in emergency medicine /urgent care short course treatments

  • applications for transition in care (discharge medications)

  • rural or tropical medicine (eg. mass drug administration campaigns)

  • direct observed therapies

New Chemical Entities Development of new therapeutic agents with low dose (high potency), where:
  • long acting delivery may be advantageous

  • where any of the above considerations may also be helpful to a patient population
