Transforming natural substances—especially those of botanical origin—into a regulated medicine is a long, highly technical, and deeply strategic process. It is a journey involving science, biotechnology, clinical validation, and a rigorous regulatory pathway defined by agencies such as ANVISA and the FDA.
Understanding this pathway is not just scientific curiosity: it means recognizing where value is created, which risks are eliminated at each stage, and why companies that master drug development build assets that are extremely valuable and difficult to replicate.
This journey follows internationally consolidated standards described in recognized references such as The Drug Development Process (FDA), technical guidelines for botanical products, toxicology frameworks, pharmacology manuals, and classical studies on pharmaceutical innovation. The structure is universal: it begins with basic science, progresses through experimental models, and culminates in clinical trials that demonstrate safety, efficacy, and quality. Every detail matters—especially with complex natural substances.
Below is a clear, accessible, and well-grounded view of what truly happens along the ANVISA/FDA pathway.
Why Start with the Regulated Pathway?
Regulated medicines differ fundamentally from supplements. While supplements may be marketed based on generic claims, a regulated medicine must demonstrate, with scientific certainty, that it:
has a plausible, evidence-based mechanism of action;
is safe within expected limits for humans;
demonstrates proven clinical efficacy;
is produced with consistency, purity, and strict control of variability.
This set of requirements creates strong entry barriers—precisely what investors look for. In the pharmaceutical industry, milestones such as the start of Phase 1, positive Phase 2 results, or submission of an NDA are traditionally associated with significant valuation jumps because they represent objective reductions in technical and regulatory risk.
Furthermore, a regulated medicine can be incorporated into health systems, hospitals, insurance plans, and clinical guidelines—something impossible for supplements. For complex conditions such as psychiatric disorders, substance dependence, or neurological diseases, this access is essential.
From Ancestral Knowledge to a Drug Candidate
Every journey begins with a scientific hypothesis. Even when the starting point is traditional knowledge—as is common with many botanical actives—empirical wisdom must be translated into testable experimental questions.
Research in pharmacognosy and pharmacology demonstrates that medicinal plants contain bioactive compounds, but transforming them into a medicine requires:
identifying relevant compounds;
defining chemical profiles and control markers;
preliminary understanding of potential mechanisms of action;
assessing theoretical toxicological risks.
At this early stage, green biotechnology plays a crucial role. Controlled agroforestry systems, genetic banks, traceability, and modern extraction techniques ensure that the plant material used in research is stable, standardized, and free of contaminants. For agencies like the FDA and ANVISA, this is critical: without consistency, there is no advancement in drug development.
The Strength of Preclinical Research: Where Technical Risk Begins to Fall
Before any substance can be administered to humans, it undergoes a robust and mandatory stage: preclinical studies. This phase, based on good laboratory practices, evaluates safety through three pillars:
a) In vitro studies
These examine how the substance interacts with cells, tissues, and specific receptors, revealing:
potential signaling pathways;
effects on cellular parameters;
early toxicity indicators.
b) In vivo studies
Animal models are used to measure:
acute and chronic toxicity;
pharmacokinetics (absorption, distribution, metabolism, and excretion);
pharmacodynamics—how the substance affects living organisms;
safe starting dose ranges.
These studies follow globally recognized standards and form the basis of IND dossiers (in the U.S.) and DDCM submissions (in Brazil).
c) Quality control and CMC
For botanical-derived pharmacological products, there is an additional requirement: undeniable proof that each batch is chemically comparable to the previous one. This involves:
validated extraction and purification methods;
documentation of solvents, equipment, and environmental conditions;
monitoring of stability and purity.
This is where much of the technical risk is mitigated—and where many poorly structured projects fail.
ANVISA vs. FDA: Opening the Regulatory Gates
After preclinical studies, the company must request authorization to begin clinical trials. Two key milestones define this step:
In Brazil: DDCM (Clinical Drug Development Dossier)
The DDCM is submitted to ANVISA and includes:
all preclinical safety data;
quality and process documentation;
detailed Phase 1 protocol;
ethics approval (CEP/Conep).
In the United States: IND (Investigational New Drug Application)
The IND serves the same purpose but follows the FDA’s structure, including:
complete pharmacology/toxicology data;
detailed CMC documentation;
scientific rationale and dose justification;
safety monitoring plan.
Acceptance of the IND is an extraordinary milestone for investors because it indicates that the FDA reviewed the data and concluded the compound is safe for human testing.
Clinical Trials: Where Evidence Is Born
Clinical trials are divided into three main phases, each with distinct objectives:
Phase 1 — Safety in Humans
Involving 20 to 80 volunteers, it measures:
overall safety;
initial adverse effects;
human pharmacokinetics and pharmacodynamics.
For investors, this is where many projects fail. Passing Phase 1 eliminates a significant portion of risk.
Phase 2 — First Signs of Efficacy
In patients with the target condition, Phase 2 aims to:
understand real therapeutic potential;
adjust dose and regimen;
define relevant clinical endpoints.
This is where major valuation increases often occur, as the first concrete signs of clinical benefit emerge.
Phase 3 — Large-Scale Confirmation
Large, rigorous multicenter studies comparing the drug with placebo or standard of care. These studies form the basis for final approval.
For a botanical product, maintaining chemical consistency across all Phase 3 batches is absolutely critical.
The Big Step: Registration and Approval
After completing clinical studies, the company prepares the regulatory dossier:
ANVISA: CTD format, aligned with updated guidelines for innovative medicines;
FDA: NDA (New Drug Application), a highly structured document compiling all safety, efficacy, and quality data.
This stage represents the point of maximum maturity for the project—when an experimental asset becomes a prescribable pharmaceutical product.
Post-Approval Life: Monitoring and Expansion
Even after approval, it remains necessary to:
monitor real-world adverse events;
conduct Phase 4 studies;
evaluate new therapeutic indications;
optimize formulations or administration routes.
It is also when opportunities arise for partnerships, mergers and acquisitions, or global licensing.
Drug Development as a Value Thesis
Why does drug development create such competitive assets?
Because the process demands:
deep scientific mastery;
adequate laboratory infrastructure;
strict compliance;
many years of continuous investment;
evidence that cannot be replicated informally.
Companies that excel in drug development build nearly impenetrable entry barriers, generate strong intellectual property, and gain significant negotiating power with major pharmaceutical companies.
Throughout this journey, each stage of drug development reduces risk, generates data, builds credibility, and increases pipeline value. This is why botanical drug development is one of the most promising areas in modern biotechnology—especially when grounded in sustainability, rigorous science, and ethical partnerships.
Conclusion: The Path That Turns Science Into Real-World Impact
The ANVISA/FDA regulatory pathway is not merely a bureaucratic sequence. It is a structured process, validated over decades, that transforms a scientific hypothesis into a safe, effective, and scalable therapeutic solution. It is a clear value-generation route: each milestone proves technical viability, reduces risk, and brings the project closer to market.
In botanical medicines, this journey integrates science, sustainability, green biotechnology, and respect for traditional knowledge—resulting in pharmaceutical innovation highly relevant to global mental health.
