Below is a transparent, step‑by‑step valuation of ONC‑201 (DLL3 T‑cell engager, ES‑SCLC, Ph2) for an in‑licensing deal.

1) Cumulative Probability of Success (PoS)

From BIO/Informa 2011–2020 oncology data:

P2 → P3 = 24.1%
P3 → REG = 47.7%
REG → APP = 93.5%

Cumulative PoS from Phase 2 to approval:

[
0.241 \times 0.477 \times 0.935 = 0.1075
]

✅ Cumulative PoS = 10.75%

This is typical for Phase 2 oncology (≈10–12%).

2) rNPV Calculation

Key Inputs (from asset file)

Peak sales = $1,600m
Net margin = 55%
Years to launch = 4
Launch → LoE = 11 years
Discount rate = 12% (established biotech convention)
Remaining R&D:
Ph2: $70m
Ph3: $300m
Filed: $25m
Total = $395m
Revenue years factor = 6.5
Revenue midpoint offset = 2 years

Step 1 — Peak Commercial Value (undiscounted)

Peak profit:

[
1,600 \times 0.55 = 880 \text{m}
]

Lifetime commercial value proxy:

[
880 \times 6.5 = 5,720 \text{m}
]

Step 2 — Discount to Present

Revenue midpoint assumed at:

[
4 + 2 = 6 \text{ years}
]

Discount factor @12% for 6 years:

[
(1.12)^6 = 1.974
]

Discounted commercial value:

[
5,720 / 1.974 = 2,898 \text{m}
]

Step 3 — Risk-Adjust by PoS

[
2,898 \times 0.1075 = 312 \text{m}
]

✅ Risk‑adjusted commercial value ≈ $312m

Step 4 — Subtract Remaining R&D

Conservatively expensed at full probability (buyer pays):

Approximate mid‑timing discount → ≈ $340m PV

(Undiscounted = $395m; weighted discounting across 1–4 yrs ≈ 14% reduction)

Step 5 — rNPV

[
312 - 340 = -28 \text{m}
]

✅ rNPV ≈ ~$0m (slightly negative, ~–$30m)

Interpretation

This confirms the note in the asset file:

“Thin rNPV given oncology PoS — structure matters.”

Why?

Oncology Phase 2 PoS is low (~11%)
Significant remaining Ph3 cost ($300m)
Crowded DLL3 space (competitive pressure)

The asset only becomes attractive if:
- Peak sales exceed $1.6B
- Development risk is partially shared
- Or structure is heavily back‑loaded

3) Deal Structuring Recommendation

Since rNPV ≈ $0m on a base-case risk-adjusted basis:

A traditional “% of rNPV” approach would imply minimal upfront.

But oncology comparables show:

Phase 2 oncology upfronts: typically $50–150m
Total biobucket: $600m–$1.5B+
Royalties: 8–15% tiered

Given competitive DLL3 space and thin base-case value:

✅ Recommended Structure (Buyer-Favorable but Market-Credible)

Upfront

$40–60m

Rationale:
- Lower end of oncology Ph2 range
- Reflects competitive risk
- Avoids overpaying for thin economics

Development + Regulatory Milestones

$350–450m

Example:
- Ph3 start: $75m
- Ph3 success: $125m
- Filing: $75m
- Approval: $100m

Commercial Milestones

$300–500m

Sales-based tiers at:
- $500m
- $1B
- $1.5B+

✅ Total Biobucket

$700m – $1.0B

Heavily success‑weighted.

Royalty

10–14% tiered

Example:
- 10% < $750m
- 12% $750m–$1.5B
- 14% > $1.5B

4) Strategic Observations

Why low upfront?

Because:

Risk-adjusted economics barely cover remaining R&D
Buyer assumes $300m+ Ph3 risk
First-mover DLL3 competitor may compress peak sales

How Seller Could Improve Economics

Co-fund Phase 3
Retain co-promotion rights
Accept lower royalty for higher upfront
Demonstrate differentiation vs incumbent

Bottom Line

Metric	Value
Cumulative PoS	10.75%
Risk‑adjusted commercial value	~$312m
PV of remaining R&D	~$340m
rNPV	~$0m (slightly negative)
Recommended upfront	$40–60m
Total biobucket	$700m–1.0B
Royalty	10–14% tiered

If you'd like, I can next:

Show sensitivity analysis (peak sales ±25%, PoS ±2 pts, margin ±5%)
Or model a co-development cost-share scenario
Or calculate the maximum justified upfront under different strategic assumptions
