Common problems (and how we fix them)

  1. Sterile Filtration Fails
    Symptoms: 0.22 µm clogging; slow filtration; yield loss
    Our Solutions: filterability as a gate for formulation development, prefilters, excipient tuning, viscosity control, and hold-time studies.
  2. Poor Drug Solubility
    Symptoms: can’t reach desired concentration; drug falls out of solution; storage temperature changes solubility
    Our Solutions: creative combinations of compendial excipients; eye on the future—evaluate if emerging technologies are enabling
  3. Painful Injections / Tolerability
    Symptoms: Sting; irritation at injection site; high injection force; clinical dropouts.
    Our Solutions: excipient swaps; shear/needle force modeling; depot/viscosifier; pH/tonicity/osmolality tuning.
  4. Poor PK / Exposure
    Symptoms: Low Cmax or AUC; short half-life; barrier-limited uptake (ocular or parenteral).
    Our Solutions: nanoparticle/lipid-based/polymer delivery platforms; controlled release formulations
  5. Expiring or Thin IP
    Symptoms: Easy to design around; 505(b)(2) risk; hard diligence questions; short IP runway after approval.
    Our Solutions: white-space mapping; diligence-ready documentation; patent specification drafting
  6. Scale-Up & Tech Transfer Problems
    Symptoms: CDMO can’t reproduce; unforeseen equipment restrictions; hold-time limitations
    Our Solutions: formulation design space studies; sterile filtration feasibility during formulation development; on-site help by our team
