American Botanical Drug Corporation

a leading contract research organization (CRO) specialized in developing botanical products to prescription botanical drugs through US FDA botanical drug IND regulatory filing, and contract manufacturer organization (CMO) for botanical product GMP manufacturing

Our Focus

  • developing botanical product (herbal medicines and hemp) for US FDA botanical drug regulatory filing and clinical development​

  • pre-clinical analytics of botanical products with complex and unknown ingredients

  • rich experience in quantitative analytics of botanical product substances using chemistry and biological techniques

  • know-how in shortening botanical drug development process from pre-clinical to proof-of-concept (phase-IIa)

  • high success rate from pre-clinical to proof-of-concept study (phase-IIa) due to safety nature of botanical products

  • marketing exclusivity for up to 5 years even in the absence of patent protection

  • expertise and capability with Good Manufacturing Practices (GMP) regulations for the clinical manufacturing of pharmaceutical formulations for clinical studies and specialty pharmaceutical products

FDA Botanical Drug Guidance

In 2004, the FDA issued Botanical Drug Development Guidance for Industry; In 2016, 2nd edition. If a drug product is derived from single plant or from mix of plants, the Guidance waives the requirement of:

  • identifying active ingredients

  • description of mechanism of action

As long as a botanical product demonstrates safety and efficacy during phase I, phase II, and phase III clinical trials, it is approved as a prescription drug on the US market. Two botanical drugs are currently on the US market:

  • Veregen (sinecatechins), a topical drug for the treatment of genital and anal warts

  • Fulyzaq (crofelemer), an oral drug for control and symptomatic relief of diarrhea in patients with HIV/AIDS on anti-retroviral therapy

There are over 600 botanical drugs in the FDA IND process.

Botanical Drug Development Pathway

​​ Modern herbal medicines in forms of pills or capsules with demonstrated safety and efficacy on large scale population are good candidates for US prescription botanical drug development:

  • choosing known safe and effective herbal medicines reduces time and cost of drug discovery

  • demonstrated safety significantly increases success rates from pre-clinical tests up to phase-IIa

  • demonstrated efficacy significantly improves success rates of phase-IIb and Phase-III trials

The technical challenge of developing CMC contents in FDA IND filing is tedious but doable. The US FDA encourages sponsors to develop hemp products through the botanical drug development pathway to bear medical claims.
