Effectively Managing
Endometriosis Pain

Endometriosis affects 1 in 10 women worldwide with debilitating pain. There are currently no good treatment options that are fertility-friendly and disease-modifying.

The Problem

Endometriosis has no cure and current therapies are inadequate for most patients.

Woman experiencing the debilitating pain of endometriosis
For millions of women, endometriosis pain is not occasional discomfort — it is a relentless, life-altering condition that affects work, relationships, fertility, and mental health.
1 in 10 women. No good treatments.
72%
Undergo Surgery

Hysterectomy or repeat laparoscopy. High cost, risk of sterilization, and pain often returns.

MOST COMMON INTERVENTION
29%
Use Opioids

Chronic use carries high risk of dependency, tolerance, and severe side effects with limited long-term benefit.

DANGEROUS DEPENDENCY CYCLE
13%
GnRH Analogues

Severe bone mineral density loss. Limited to 24 months of use. High cost and significant side effects.

SEVERE SAFETY TRADEOFFS
31%
Hormonal Birth Control

Ineffective for many. Suppresses symptoms without addressing underlying disease. Not fertility-friendly.

SYMPTOM MASKING ONLY

1 in 10 women of reproductive age suffer from endometriosis with no effective, fertility-preserving therapy available today.

INVESTIGATIONAL DISEASE-MODIFYING APPROACH

Our Solution

Our lead investigational asset leverages a well-characterized small molecule with decades of established safety data — reformulated for endometriosis with proprietary composition-of-matter IP.

Dual Mechanism of Action

1
Modulating Inflammatory Pathways

Normalization of multiple dysregulated inflammatory cascades, including IL-1β, TNF-α, IL-6, IL-17, and NF-κB that drive endometriosis pathology, without suppressing the regular functioning of these pathways to prevent infection.

2
Preventing New Lesion Formation

Refluxed menses escaping into the peritoneum utilize dysregulated autophagy to survive, implant, and create endometriotic lesions. Normalization of autophagy inhibits this pathology.

NON-HORMONAL
DECADES OF SAFETY DATA
KEY DIFFERENTIATORS
Disease-Modifying Potential

Designed to go beyond symptom suppression by addressing drivers of lesion-associated pain and progression.

Well-Characterized API

An established safety profile from decades of use in other indications.

Optimized Presentation

Proprietary SLBST formulation designed to simplify compliance and improve long-term safety.

Strong IP Position

Issued method-of-use patents. Pending composition-of-matter IP.

THE POTENTIAL OF OUR APPROACH
A potential path from chronic pain to a more normal life.

By addressing key drivers of endometriosis rather than masking symptoms, our investigational program offers the possibility of meaningful, lasting relief — while preserving fertility and long-term health.

PUBLISHED RATIONALE

The Science

Independent preclinical and observational findings provide the foundation for our approach in endometriosis. Full datasets available in the data room for qualified investors.

Preclinical Foundation
ENDOMETRIOSIS MODELS
60%
FEWER LESIONS

In established models, the approach produced 60% fewer lesions. Half of treated subjects developed no lesions at all.

Supporting data from published academic models. Detailed results in the confidential data room.
Observational Rationale
Reduced Opioid Use
68%
Associated with significantly fewer opioids required for pain management in relevant patient populations.
Lower Endometriosis Incidence
50%
Associated with ~50% lower cumulative incidence of endometriosis diagnoses.
Independent academic observations. Full context provided in the confidential data room.
