Rheumatoid arthritis remains a large, chronic and growing health burden.
THCA Therapeutics is initially focused on rheumatoid arthritis (RA), a systemic autoimmune disease with measurable inflammatory biology, established development endpoints and substantial unmet need despite multiple approved treatment classes.
people living with RA worldwide
A global disease affecting joints, function, work capacity and quality of life.
of people living with RA are women
The disease burden is disproportionately carried by women.

Existing therapies can transform outcomes—yet important limitations remain.
THCA PURE™ Oral is not presented as superior to approved medicines. The development objective is to determine whether purified THCA can become a differentiated oral candidate with an interpretable benefit–risk profile for patients who need additional options.
Methotrexate and related agents
- Established first-line role and extensive clinical experience
- Oral or injectable options
- Monitoring for hepatic, hematologic and other toxicities
- Not every patient achieves sufficient disease control
TNF, IL-6 and other targeted biologics
- Established efficacy in moderate-to-severe disease
- Targeted mechanisms and multiple approved options
- Usually administered by injection or infusion
- Infection risk, monitoring and high system cost
JAK inhibitors
- Convenient oral administration
- Established clinical efficacy in selected patients
- Important patient-selection and monitoring requirements
- FDA boxed warnings include serious cardiovascular, cancer, clot and mortality risks
THCA PURE™ Oral
- Intended as a standardized oral pharmaceutical candidate
- Designed around purified THCA in its acidic form
- RA-first, evidence-led development strategy
- Human efficacy, safety, dose and comparative value remain unknown
An oral, non-intoxicating-by-molecule-design development candidate that could occupy a differentiated position if future studies establish reproducible exposure, acceptable safety and clinically meaningful activity.
Validated findings across selected experimental models.
The dashboard below retains the clear progress-bar format while distinguishing quantitative effect estimates, statistically significant directional findings and areas where direct tetrahydrocannabinolic-acid evidence has not yet been established.
Quantitative bar Percentage reported in the paper or transparently estimated from a published figure.
Significance bar The study reports a statistically significant directional result; bar length is not an effect-size percentage.
Evidence-gap bar No validated direct tetrahydrocannabinolic-acid effect size was found for the stated model.
Rheumatoid Arthritis Model
Collagen-induced arthritis in DBA/1 mice · 20 mg/kg/day intraperitoneally · n=9 per group
Approximate percentages are endpoint estimates visually digitized from Figures 5c and 8a, 8b and 8f of Reference 1. They are not exact author-reported effect-size percentages and should be read as approximate comparisons with the untreated CIA group.
Reference 1 ↓Neuroinflammation Model
LPS-activated BV-2 murine microglia and primary mixed glia · 22-hour treatment
The 40–95% nitric-oxide range is stated in Reference 2. The paper reports concentration-dependent iNOS attenuation and a significant TNF-α result in primary glia. Cellular findings do not establish human brain exposure or clinical neuroprotection.
Reference 2 ↓Neurodegeneration Model
3-nitropropionic-acid mouse model of striatal degeneration · 20 mg/kg/day · four days · n=9
Reference 3 reports statistically significant directional findings but does not provide a single text-reported percentage for each endpoint. Hatched bars therefore communicate significance only—not effect magnitude. This was not a 6-OHDA Parkinson’s rat model.
Reference 3 ↓Respiratory Inflammation Model
Future model-selection area for THCA PURE™ Inhale
A frequently cited ovalbumin-asthma paper uses “THCA” as an abbreviation for 3,4,5-trihydroxycinnamic acid, not tetrahydrocannabinolic acid. Other airway-inflammation findings commonly cited in cannabinoid reviews concern CBD. They cannot be presented as direct evidence for THCA PURE™ Inhale.
Respiratory inflammation remains a future hypothesis. Product-specific pulmonary exposure, local tolerability and disease-model effects must be generated in route-appropriate studies.
Reference 4 ↓Further model-level support for biological activity.
These published models broaden the scientific rationale but do not represent active THCA Therapeutics clinical indications.
Rat and house-musk-shrew models
0.05–0.5 mg/kgIntraperitoneal THCA reduced lithium-chloride-induced conditioned gaping in rats and vomiting in house musk shrews. The reported effect was CB1-antagonist-sensitive.
Reference 5 ↓Diet-induced-obesity mouse model
12 weeksPublished THCA-A treatment was associated with reduced adiposity, improved glucose tolerance and insulin sensitivity, and less hepatic steatosis and inflammatory-cell infiltration.

All findings shown are preclinical. They do not establish that THCA PURE™ Oral or THCA PURE™ Inhale is safe, effective, clinically validated or superior to an approved therapy. Animal doses and laboratory concentrations must not be interpreted as human doses.
One focused platform. Two product programs.
THCA PURE™ is the shared pharmaceutical-development platform. It connects qualified materials, analytical methods, controlled manufacturing, formulation development, packaging, regulatory planning and future clinical evidence.
