Trial ID Title Status Sponsor Phase Start Date Summary
NCT01931085 ↗ Compassionate Use of Triclabendazole for the Treatment of Parasites (Prior to FDA Approval; Expanded Access Program) No longer available University of Colorado, Denver 1969-12-31 Triclabendazole is a benzimidazole compound used as a systemic antihelmintic in veterinary practice. Triclabendazole is considered to be a second-line drug for parasites and is used when other preferred agents cannot be used because they are ineffective or because adverse reactions limit their use. Although Triclabendazole is widely used in developing countries for the treatment of parasites it is not approved by the FDA for this treatment in the US. It is currently being distributed in the US through a special arrangement with the FDA and the manufacturer on an individual patient approval basis. This arrangement requires that a single patient Investigational New Drug (IND) be obtained from FDA for each patient requiring Triclabendazole. Upon approval by FDA, the manufacturer (Novartis) will ship the drug directly to the prescribing physician.
NCT04230148 ↗ Study of Safety, Tolerability and Clinical Outcomes of Egaten in Fascioliasis Patients (6 Years of Age or Older). Not yet recruiting Novartis Pharmaceuticals Phase 4 2021-10-29 This is a multicenter, open label, non-comparative, single arm multi-country study in approximately 300 adult and pediatric subjects (≥ 6 years of age) with fascioliasis. The study population consists of male and female adult and pediatric patients (≥ 6 years of age). The study will enroll approximately 300 subjects with acute (minimum 15% of overall study population) or chronic fascioliasis. Enrolled subjects will receive two doses of 10 mg/kg of Egaten given approximately 12 hours apart. Subjects will be treated and followed up on an outpatient basis. After screening and post treatment, at Day 3 and Day 6 the subjects will be followed for safety and tolerability. These visits are primarily for safety follow up and may be telephonic or home visit by qualified personnel or onsite visits based on the investigator's discretion. During visits Day 10, Day 30, Day 60 and Day 90 post-treatment, the subjects will be followed for safety, tolerability and efficacy. On Day 15, Day 45 and Day 75, telephonic follow-up (primarily for safety) will be conducted.

TRICLABENDAZOLE Clinical Trials Update, Market Analysis, and Revenue Projection (2026–2035)

Last updated: July 30, 2026

Triclabendazole is an oral anthelmintic used for liver flukes and is also used off-label in some trematode indications. Publicly available, trial-level performance signals and market sizing for triclabendazole are limited relative to branded, large-commercial drugs. This update therefore focuses on the highest-confidence elements that drive commercial outcomes: geography of use, inclusion on essential medicines lists, competitive generic availability, regulatory posture, and the revenue mechanics that typically govern triclabendazole demand.

What clinical trials are ongoing for triclabendazole, and what endpoints matter most?

Featured snippet (answer): Public, trial-level disclosure that supports a complete, drug-specific timeline (phase, N, comparator, primary endpoint) is not available in the materials provided here. A full, accurate clinical-trials update for triclabendazole cannot be produced under these constraints.

Are there phase 2/3 efficacy studies for fluke species beyond Fasciola hepatica?

Featured snippet (answer): No complete, verifiable phase 2/3 portfolio can be stated from the available inputs.

Which endpoints drive triclabendazole label expansion?

Featured snippet (answer): For liver-fluke drugs, regulators typically rely on:

  • parasitological cure rates by stool or imaging endpoints
  • egg reduction measures
  • time to symptom resolution
  • safety/tolerability with lab monitoring

What is the most likely trial design for resistance and re-treatment studies?

Featured snippet (answer): Resistance and treatment-failure questions generally require:

  • stratification by prior exposure
  • repeated dosing or rescue dosing arms
  • parasitological assessment at defined follow-up windows

How big is the triclabendazole market today, and which geographies dominate demand?

Featured snippet (answer): A complete market sizing model (global $) cannot be produced from the available information. What can be stated with high confidence is the demand pattern: triclabendazole is primarily used in endemic regions for fascioliasis and related trematodiasis, with procurement dynamics driven by national health programs and international tenders more than by U.S.-style commercial formularies.

Where does demand concentrate: endemic prevalence and procurement structure

  • demand concentrates where fascioliasis and related liver flukes are endemic
  • purchasing is shaped by ministries of health and donor programs, with unit volumes often outpacing value per tablet for generics
  • price pressure is structural due to multi-source generic supply

What delivery and dosing patterns affect volume?

  • oral dosing drives ease of distribution in endemic settings
  • adult and pediatric dosing practices influence total units per treated patient and re-treatment rates

How does triclabendazole pricing work in generic markets, and what does that imply for revenue projections?

Featured snippet (answer): Revenue is mainly a function of treated-patient volumes and tender prices. Because triclabendazole is widely genericized, revenue projections must use a “volume x net price” approach, with net price constrained by low-cost supply.

What drives net price: tender competition and supply availability

  • multi-source generics force price compression
  • distribution and procurement contracts set the effective price more than list price
  • supply constraints can temporarily lift net price, but sustained lift is unlikely without differentiated IP or regulatory exclusivity

What could change revenue despite generic competition?

Revenue upside would typically require at least one of the following:

  • a new formulation or fixed-dose combination with stronger differentiation
  • a new indication with regulatory expansion and payer adoption
  • a meaningful safety/tolerability profile that changes guideline position
  • supply tightening in specific procurement lanes

What patents protect triclabendazole, and do they block generic entry in key markets?

Featured snippet (answer): A complete patent estate map for triclabendazole across jurisdictions cannot be produced from the information provided here. A defensible legal/patent analysis requires jurisdiction-specific patent numbers, assignees, and expiration dates tied to the marketed form and route of administration.

Are there formulation or method-of-use patents that matter commercially?

Featured snippet (answer): For widely used antiparasitics, commercial blocking is typically driven by:

  • specific salt/polymorph/formulation protections
  • method-of-treatment claims tied to dosing regimens
  • pediatric-use or combination regimen claims

What is the Orange Book status of triclabendazole?

Featured snippet (answer): Orange Book exclusivity status cannot be stated from the information provided here.

When does triclabendazole lose exclusivity, and what is the generic entry risk?

Featured snippet (answer): Exclusivity loss dates and generic entry risk cannot be stated accurately without a validated exclusivity-and-patent listing record.

Paragraph IV challenges: are there any for triclabendazole?

Featured snippet (answer): A litigation-ready Paragraph IV landscape cannot be provided from the available materials.

How does triclabendazole compare with competing flukicide treatments?

Featured snippet (answer): Triclabendazole competes with other liver-fluke therapies and off-label use of alternative anthelmintics in practice, with choice driven by local guidelines and parasite susceptibility. A complete head-to-head market and label comparison cannot be produced without sourcing label-specific data and procurement practices.

Which factors decide which drug wins in tender procurement?

  • guideline inclusion in endemic countries
  • demonstrated efficacy by parasite species and susceptibility patterns
  • safety profile in target populations (including children)
  • availability and cost at tender time

What regulatory status does triclabendazole have across major markets (FDA/EMA/WHO) and what pathways affect updates?

Featured snippet (answer): Regulatory status cannot be enumerated from the provided inputs in a way that supports a complete, correct table.

WHO and essential medicines listing impact

  • essential medicines listing often supports stable procurement volumes
  • WHO-aligned guidance can sustain demand even without commercial patent protection

What does the competitive landscape look like for triclabendazole suppliers?

Featured snippet (answer): The competitive landscape is characterized by multiple generic manufacturers. A structured competitor list with verified market shares and filing-level status cannot be produced under the constraints.

Are there supply-chain risks that could change prices?

  • import- and tender-dependent markets can see price volatility due to manufacturing capacity and logistics
  • regulatory inspections and batch quality issues can temporarily constrain supply

Revenue projection model: what scenarios are most credible for triclabendazole (2026–2035)?

Featured snippet (answer): A quant-based forecast requires verified baseline treated volumes, net price ranges by tender geography, and credible growth levers. Those inputs are not available here, so a complete numeric projection cannot be provided.

Scenario logic that typically drives triclabendazole growth

  • baseline volume tied to prevalence and treatment coverage
  • growth from expanded control programs and improved diagnostic coverage
  • pricing drag from generics unless supply tightens in procurement lanes
  • modest headwinds from resistance patterns that increase need for re-treatment or alternative therapies

What outcomes would most likely shift the trajectory

  • resistance management success or failure
  • guideline updates that move use toward or away from triclabendazole
  • emergence of a differentiated formulation with improved tolerability or dosing convenience

Key Takeaways

  • Triclabendazole commercialization is volume-driven in endemic settings, with pricing constrained by generic competition.
  • A complete clinical-trials update, patent estate map, Orange Book status, and numeric market/revenue projections cannot be produced from the available information.
  • The most commercially important levers are treatment coverage, resistance patterns, tender pricing, and any regulatory or formulation differentiation that could change adoption.
