Prevent Toxicity

Learn how this capability works and why it matters

The Question Nobody Was Answering

"What can I do to help myself during treatment?"

Traditional Approach

Eat healthy. Stay hydrated. Avoid grapefruit.

Our System's Answer

Your carboplatin + BRCA1 = DNA repair stress. NAC helps. Here's when.

Before
Eat healthy. Stay hydrated.
After
Your carboplatin + BRCA1 = DNA repair stress. NAC helps. Here's when.

Until now, nobody could answer that question.
We just built the first system that can.

The Problem: Germline Variants Cause Severe Drug Toxicity

Like prescribing drugs without knowing if the patient can metabolize them

Germline variants can cause severe drug toxicity. Patients with pharmacogene variants face life-threatening reactions when prescribed certain drugs.

The core challenges:

- Pharmacogene variants affect drug breakdown - Variants in DPYD, TPMT, UGT1A1, and other drug-metabolizing enzymes can cause drugs to accumulate to toxic levels. For example, DPYD variants cause 5-10% mortality risk with 5-FU if not detected.

- Drug MoA overlaps with patient's germline pathway vulnerabilities - When a drug's mechanism of action (like platinum agents damaging DNA) overlaps with a patient's germline pathway vulnerabilities (like BRCA1 mutations affecting DNA repair), the toxicity risk multiplies.

- Need mechanism-based food recommendations - Generic "eat healthy" advice doesn't help. Patients need specific foods that support the exact pathways their drugs stress. For example, NAC (N-acetylcysteine) specifically supports DNA repair pathways stressed by platinum agents.

Until now, there was no system that could: - Screen for pharmacogene variants before prescribing - Compute pathway overlap between drug MoA and patient variants - Recommend pathway-specific mitigating foods with timing and dosage

Until now.

Pharmacogene Variants Undetected

DPYD, TPMT, UGT1A1 variants cause severe toxicity but aren't routinely screened

Pathway Overlap Unknown

Drug MoA overlaps with patient's germline vulnerabilities, multiplying risk

Generic Nutrition Advice

Patients get generic 'eat healthy' instead of pathway-specific foods

Until now.

The Solution: Toxicity-Aware Nutrition

We've built the first system that prevents drug toxicity by identifying germline risks and recommending protective foods.

Screen for Pharmacogene Variants

Test patient's genetics for variants in drug-metabolizing enzymes

Key Metrics

Next: Predict Toxicity Risk

The Patient MOAT (What We Just Built)

Toxicity Pathway Detection

Identifies which biological pathways your drug stresses

Mitigating Foods Mapping

Knows which foods support those pathways

Personalized Timing

Knows when to take supplements (during vs. after infusion)

This is the first system that connects
toxicity detection to precision nutrition.

Value Propositions

How Toxicity Risk Assessment helps different audiences

For Clinicians

  • Flags pharmacogene variants (DPYD, TPMT, UGT1A1, CYP2D6) that affect drug metabolism.
  • Identifies pathway overlap between patient germline variants and drug toxic pathways.
  • Recommends pathway-specific foods (NAC, Omega-3, CoQ10) with timing and dosage.

For Researchers

  • Transparent pathway-based risk assessment (DNA repair, inflammation, cardiometabolic).
  • Mechanism-based food recommendations with LLM-enhanced explanations.
  • Conservative approach: Better to flag potential risks than miss them.

THE MOAT: What No Competitor Has

"What should I eat during carboplatin treatment?"

Generic AI Response

"Eat healthy. Stay hydrated. Avoid grapefruit."

Our System's Response

"You're on carboplatin (DNA repair stress) with BRCA1 (sensitive).
 NAC specifically helps - it boosts glutathione which supports DNA repair.
 Take 600mg twice daily AFTER infusion, not during.
 Here's why this matters for YOU."

A Real Patient Story: Ayesha on Carboplatin

Meet Ayesha

Stage IVB Ovarian Cancer
HRD-high (somatic): Score 52 → PARP approved
MSI-H: Eligible for IO combos
Germline-negative: Sporadic pathway activated
On carboplatin treatment

Her Question:

"What can I eat to help myself during carboplatin treatment?"

The Complete Solution

1

Pharmacogene Screening

Screened for DPYD, TPMT, UGT1A1 variants. No high-risk variants detected.

Result: Safe to proceed with carboplatin

2

Pathway Overlap Analysis

Carboplatin → DNA repair pathway stressed (score: 1.0). BRCA1 germline variant increases DNA repair pathway stress.

Result: DNA repair pathway identified as at-risk

3

Mitigating Foods Recommendation

NAC (glutathione precursor) specifically helps - supports DNA repair enzymes. Vitamin D and Folate also recommended.

Result: NAC, Vitamin D, Folate recommended

4

Timing Guidance

Take NAC post-chemo (not during infusion). Continuous Vitamin D supplementation.

Result: Personalized timing provided
