Executive Summary
Neurocrine Biosciences has TWO TIER 1 opportunities for Ada Patient Finder: INGREZZA for tardive dyskinesia and CRENESSITY for congenital adrenal hyperplasia. Both drugs target chronically underdiagnosed populations with clear diagnostic pathways that Ada's symptom assessment can navigate.
Key Insight: Neurocrine is NOT actively pursuing patient finding solutions, creating a significant opportunity to educate them on underdiagnosis and position Ada as the solution.

MASSIVE FUTURE OPPORTUNITY: If CRENESSITY pursues nonclassic CAH indication (off-label or label expansion), addressable undiagnosed jumps to 400,000 patients with $1.2B Ada revenue opportunity (at full addressable).
Clinical & Diagnostic Profile
- Symptoms (Nonclassic CAH, the undiagnosed population): Hirsutism, acne, irregular periods, infertility, male-pattern hair growth
- Diagnostic Delay: DECADES — diagnosed in 4th, 5th, 6th, even 8th decade of life; average 10-30 years from symptom onset
- Common Misdiagnoses: PCOS (most common), idiopathic hirsutism, obesity, infertility
- Who Diagnoses: Endocrinologist (definitive), often starts with OB-GYN or PCP
- Diagnostic Trigger: Infertility workup, severe hirsutism, ACTH stimulation test
- Treatment Duration: Chronic (lifelong hormone replacement)
- Treatment Line: ADJUNCTIVE to hydrocortisone (first-line is glucocorticoid replacement; CRENESSITY added when androgen control inadequate)
Ada Suitability Assessment
| Dimension |
Score |
Rationale |
| Ada Surface Ability |

Pitch Hook:
"CRENESSITY captured only 10% of CAH patients in its first year — Ada Patient Finder can navigate the remaining 8,800 undiagnosed adults with decades-long diagnostic delays before Crinetics' competitor launches in 2029."
Extended Hook (Nonclassic CAH):
"Even more compelling: if you pursue nonclassic CAH (off-label or label expansion), we unlock a $1.2B opportunity finding 400,000 women who've been misdiagnosed as PCOS for decades."
Strategic Signals from Earnings
- Q4 2025: "Captured ~10% of addressable patients on chronic therapy"
- "First-in-disease launch" language = market creation mindset
- 2,048 patient enrollments in 2025 (strong early momentum)
- 80%+ reimbursement coverage by Q4 2025
- Gap identified: Focus on enrolling diagnosed patients, not diagnosis expansion
Competitive Landscape & Urgency
- First-to-market: Non-steroidal adjunctive CAH therapy (~30-35% projected market share)
- Key Competitor: Atumelnant (Crinetics) — Phase 3, expected approval 2028-2029
- Competitive Threat: Atumelnant showed superior Phase 2 data (better androgen control)
- URGENCY: 3-4 year window to lock in market share before competitor launches
- UBS downgrade: Peak sales lowered from $2.5B to $1.7B due to competition
TIER 3 OPPORTUNITIES (OPPORTUNISTIC)
3. INGREZZA (valbenazine) — Huntington's Disease Chorea
Annual Revenue Est: $50-100M (bundled with TD)
Peak Revenue Est: $65M
Approval Date: August 2023
Why TIER 3?
- Small market: Only 1,300 addressable undiagnosed patients (US)
- Genetic diagnosis required: Limits Ada's direct value (can flag symptoms but genetic testing required)
- Low company priority: HD bundled into INGREZZA franchise, no separate patient finding efforts
- Ada revenue opportunity: $65K-$325K annually (at 1-5% capture)
Recommended Approach: Bundle HD chorea with INGREZZA TD pitch as added value. "We'll navigate both TD and HD chorea populations to INGREZZA."
TIER 2 OPPORTUNITIES: TRIAL FINDER (PIPELINE)
4. Osavampator — Major Depressive Disorder (Phase 3)
Status: Phase 3 (launched Jan 2025)
Data Expected: Late 2026 - Early 2027
Mechanism: AMPA receptor modulator (first-in-class)
Trial Finder Opportunity
- Market: 21M MDD patients, 6-10M treatment-resistant depression
- Recruitment challenge: Moderate (need patients on stable antidepressant with inadequate response)
- Ada capability: Can identify MDD patients, assess treatment response, pre-screen for inclusion criteria
- Fit score: 6.5/10
Future In-Market Finder Opportunity (If Approved)
- Massive market: 6-10M treatment-resistant patients
- Strong Phase 2 data: Effect size 0.73 (vs typical 0.2-0.3 for antidepressants)
- If approved: Would become TIER 1 In-Market Finder opportunity
Pitch Hook:
"Osavampator's Phase 3 trials need treatment-resistant depression patients — Ada assesses 50,000+ MDD patients monthly and can pre-screen for your inclusion criteria."
5. Direclidine — Schizophrenia (Phase 3)
Status: Phase 3 (ongoing)
Data Expected: 2027
Mechanism: M4 muscarinic agonist (novel)
Trial Finder Opportunity
- Market: 3.7M US schizophrenia patients, 1.5M untreated
- Recruitment challenge: Moderate-High (need acute schizophrenia or stable for relapse prevention)
- Ada capability: Can identify family caregivers, screen for prodromal symptoms, navigate to trial sites
- Limitation: Acute psychosis limits patient self-assessment
- Fit score: 6.0/10
Future In-Market Finder Opportunity (If Approved)
- Large market: 1.5M untreated in US (40% treatment gap)
- Novel mechanism: M4 agonist may offer efficacy/tolerability advantages
- If approved: Would become TIER 1 In-Market Finder opportunity
Pitch Hook:
"Direclidine's relapse prevention trial needs stable schizophrenia patients — Ada can identify family caregivers and navigate them to your trial sites."
STRATEGIC RECOMMENDATIONS
Recommended Next Steps
- Prioritize INGREZZA (TD) and CRENESSITY outreach
- Target: Commercial leadership, Market Access, Patient Services teams
- Both are TIER 1 with strong fit scores and clear economic value
- Lead with underdiagnosis data in pitch
- INGREZZA: "60% of TD patients undiagnosed despite visible symptoms"
- CRENESSITY: "Nonclassic CAH diagnosed 10-30 years after symptom onset, often misdiagnosed as PCOS"
- Emphasize patent/competitive urgency
- INGREZZA: "5-6 years until generic entry (2031-2032)"
- CRENESSITY: "3-4 years until atumelnant competition (2028-2029)"
- Offer pilot programs
- Start with proof-of-concept (100-500 patients navigated)
- Measure: time-to-prescription, conversion rate, revenue impact
- Low-risk way for Neurocrine to test Ada's value
- Monitor pipeline for future opportunities
- Osavampator (MDD) and direclidine (schizophrenia) are TIER 2
- Establish Trial Finder relationship now
- Position for future In-Market Finder post-approval
Key Educational Points for Neurocrine
- Underdiagnosis is a major barrier to revenue growth — 60% TD undiagnosed, decades of CAH delay
- Salesforce expansion alone won't solve diagnosis gaps — need upstream patient identification
- Ada navigates patients to existing prescriber base — not a new market access challenge
- Patient Finder is "market expansion," not DTC marketing — aligns with Neurocrine's positioning
- Time-limited opportunities due to patents/competition — act now to maximize remaining exclusivity
