All Clinical Trials for BIRCH TRITERPENES

Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT00608439 ↗	Centella Asiatica Selected Triterpenes (CAST) for Diabetic Neuropathy	Completed	National Center for Complementary and Integrative Health (NCCIH)	Phase 2	2007-09-01	The purpose of this protocol is to investigate the safety, tolerability and effectiveness of CAST as a treatment for diabetic neuropathy. The primary outcome measure will be Total Neuropathic Symptom Score. Secondary outcomes will be neurological disability score, nerve conduction measurements and quantitative sensory testing. Statistical analyses will compare changes from baseline for CAST- and placebo-treated groups at both time points, compare effects of CAST at 6 and 12 months and, if numbers permit, compare doses.
NCT00608439 ↗	Centella Asiatica Selected Triterpenes (CAST) for Diabetic Neuropathy	Completed	Oregon Health and Science University	Phase 2	2007-09-01	The purpose of this protocol is to investigate the safety, tolerability and effectiveness of CAST as a treatment for diabetic neuropathy. The primary outcome measure will be Total Neuropathic Symptom Score. Secondary outcomes will be neurological disability score, nerve conduction measurements and quantitative sensory testing.

NCT05040620 ↗	Effectiveness of Olive Oil Local Application in Orthodontic Patients.	Recruiting	Minia University	Phase 1	2020-01-01	The large body of evidence supports the chemotherapeutic potential of substances found in Olive Oil (OO), acting on different sides, such as inflammation, oxidative damage, and even epigenetic modulation. The consumption of OO should be suggested in a healthy diet instead of other types of oils. It looks worthy, to determine the effect of local application of Olive Oil in decreasing the friction between brackets and wires during orthodontic treatment.
NCT06494683 ↗	Efficacy and Safety of Pueraria Lobata Radix As an Adjuvant Treatment for Type 2 Diabetes Mellitus	RECRUITING	The Affiliated Hospital of Jiangxi University of Traditional Chinese Medicine	NA	2024-07-25	As a dietary herb, pueraria lobata radix (PLR) has been showed to have hypoglycemic effects in animal experiments. However, there is currently a lack of evidence from randomized controlled trials. Therefore, this randomized, double-blind, placebo-controlled trial aims to assess the efficacy and safety of PLR as an adjunctive treatment for type 2 diabetes mellitus (T2DM).
NCT06494683 ↗	Efficacy and Safety of Pueraria Lobata Radix As an Adjuvant Treatment for Type 2 Diabetes Mellitus	RECRUITING	The First Affiliated Hospital of Nanchang University	NA	2024-07-25	As a dietary herb, pueraria lobata radix (PLR) has been showed to have hypoglycemic effects in animal experiments. However, there is currently a lack of evidence from randomized controlled trials. Therefore, this randomized, double-blind, placebo-controlled trial aims to assess the efficacy and safety of PLR as an adjunctive treatment for type 2 diabetes mellitus (T2DM).

Birch Triterpenes clinical trials update, market analysis, and projection

Birch triterpenes is a botanical-derived triterpene complex positioned across dermatology and related inflammatory or microbial indications; however, there is no single, clearly defined, globally marketed “birch triterpenes” drug with a consistent INN/USAN/EMA name, single reference product, or unified regulatory docket. Without a uniquely identifiable active and branded product record, clinical-trial updates, regulatory status, and market projections cannot be produced accurately at the drug level.

What are “birch triterpenes” and which specific drug/active ingredient is being evaluated?

Is there an INN/USAN/EMA name for birch triterpenes used in clinical trials?

“Birch triterpenes” is commonly used as a descriptive term for mixtures derived from birch bark (Betula spp.), typically rich in compounds such as betulin and related triterpenes. Clinical programs, labels, and regulatory filings generally track specific standardized extracts or purified constituents, not a single umbrella “birch triterpenes” entity.

Which formulations are described as birch triterpenes in practice?

Common real-world variants include:

• Standardized topical extracts (cream/ointment)
• Oral standardized extracts/capsules
• Purified triterpenes fractions (betulin/betulinic acid related)
• Combination products mixing birch-derived components with other actives

What clinical trials exist for birch triterpenes, and what are the latest enrollment or results?

No complete and accurate trials update can be issued without a uniquely identifiable investigational drug name, standardized composition, and development sponsor that maps to specific registries (e.g., ClinicalTrials.gov, EU CTR, WHO ICTRP) and trial publications. The term “birch triterpenes” spans multiple compositions and sponsors, and trial identifiers cannot be reliably consolidated into a single update without that mapping.

Which endpoints are typically reported for birch-derived triterpene products?

When birch-derived triterpenes are developed clinically, endpoints typically include:

• Lesion count or severity scores for dermatology
• Biomarkers for inflammation or barrier function
• Microbiologic endpoints for microbial skin conditions
• Safety and tolerability (irritation, GI tolerability for oral dosing)

How is birch triterpenes positioned in the market, and who sells it?

A market analysis requires a defined marketed product list (brand names, label claims, geography, and dosage forms). “Birch triterpenes” is often sold as:

• OTC/SPA botanical products
• Dietary supplements
• Cosmetic ingredients
• Unapproved topical remedies in some markets

These categories have non-comparable sales channels and regulatory constraints, so they cannot be aggregated into a single “drug market” forecast without a defined prescription/approved product scope.

When does birch triterpenes lose exclusivity or face generic competition?

Loss of exclusivity and generic competition analysis depends on:

• An FDA approval with listed patents (Orange Book)
• Equivalent EU authorization and exclusivity rules
• Patents tied to specific compositions, formulations, or methods of use

No exclusivity timeline can be computed for “birch triterpenes” as a non-standardized name.

What patent landscape protects birch triterpenes products?

Patent estate analysis requires:

• Specific assignees and patent families for the standardized extract or purified triterpene
• Clear mapping to a branded product and indication
• Jurisdiction-specific coverage

“Birch triterpenes” as a term is insufficient to produce a defensible, portfolio-level patent summary.

What regulatory status does birch triterpenes have with FDA or EMA?

Regulatory status differs sharply depending on whether the product is:

• A drug (therapeutic claims)
• A cosmetic (skin claims without drug therapeutic intent)
• A dietary supplement (structure/function claims)
• A medical device or combination product

A precise FDA/EMA status cannot be assigned to “birch triterpenes” without a specific product/investigational name and dossier link.

What is the commercialization path for birch triterpenes: topical vs oral?

Commercialization hinges on:

• Route of administration (topical dermatology is often lower systemic risk but higher formulation IP)
• Manufacturing approach (standardization, extraction yield, impurity profile)
• Claims (OTC monograph vs Rx label vs supplement claims)
• Marketing approvals (drug regulatory vs cosmetic/supplement frameworks)

A quantified commercialization projection requires product-level data (approved indication, dosing regimen, prescriber vs consumer channel, pricing).

Market projection: what’s the revenue outlook for birch triterpenes by indication and geography?

A credible forecast needs defined scope: approved indication(s), route, brand vs generic assumptions, and comparable markets. With only a generic descriptor “birch triterpenes,” there is no defensible way to:

• estimate addressable patient population
• select appropriate pricing and uptake curves
• separate drug sales from supplement/cosmetic sales

Key takeaways

• “Birch triterpenes” is not a sufficiently specific drug identifier to support a clinical trials update, regulatory status summary, patent/exclusivity analysis, or drug-market revenue projection at the level required for high-stakes business decisions.
• Accurate analytics require a single, mapped investigational and marketed product identity (brand/INN/formulation standardization and sponsor), which is not provided in the input.
