Spotlight Therapeutics \USA

Spotlight Therapeutics was a clinical-stage biotechnology company developing precision immunotherapies for cancer treatment. Founded in 2017 by Mary Haak-Frendscho, a veteran immunologist, the company aimed to engineer T-cells to target tumor-specific neoantigens—mutations unique to each patient's cancer. The value proposition was personalized cancer immunotherapy that could overcome the limitations of checkpoint inhibitors and CAR-T therapies by creating truly individualized treatments. With $100M from marquee investors like GV and SoftBank, Spotlight represented the convergence of computational biology, next-generation sequencing, and cellular engineering. The 'why now' was compelling: decreasing costs of genomic sequencing, advances in neoantigen prediction algorithms, and clinical validation of immunotherapy as a cancer treatment modality. However, the company faced the brutal realities of translating computational predictions into clinical efficacy, navigating complex manufacturing at scale, and competing in an increasingly crowded personalized medicine landscape where the technical risk far exceeded even generous capital reserves.

Pivot Concept

+

An AI-native neoantigen discovery and validation platform that flips the Spotlight model: instead of predicting neoantigens computationally and hoping they work clinically, Onco-Forge uses high-throughput experimental screening (microfluidics, organoids, humanized mice) to empirically identify which neoantigens actually generate tumor-killing T-cells, then reverse-engineers the predictive models. The platform targets 'public neoantigens'—recurrent mutations shared across 20-40% of patients in specific cancer types (e.g., KRAS G12C in lung cancer, IDH1 R132H in gliomas)—enabling off-the-shelf mRNA vaccines rather than personalized manufacturing. The wedge is a data-as-a-service model: pharma partners pay for access to validated neoantigen libraries and predictive models, de-risking their internal programs. The long-term play is a pipeline of off-the-shelf cancer vaccines with $50K price points (vs. $500K for personalized) and scalable manufacturing via mRNA platforms (Moderna/BioNTech CDMO partnerships). This is not a 'rebuild Spotlight' idea—it's a recognition that the personalized thesis was wrong, but the underlying biology (neoantigens can work) remains valid if approached with better tools and business model.

Execution Plan

+

Phase 1

+

Step 1 (Wedge): Partner with 2-3 academic cancer centers to access tumor samples and clinical data for KRAS-mutant lung cancer (30% of NSCLC, ~70K US patients annually). Use high-throughput screening to identify the top 10 KRAS G12C neoantigen variants that generate CD8+ T-cell responses in >50% of patient samples. Publish results in Nature Medicine to establish scientific credibility. Timeline: 12-18 months, $5M.

Phase 2

+

Step 2 (Validation): Launch a Phase I clinical trial of an off-the-shelf mRNA vaccine encoding the top 3 KRAS neoantigens in combination with pembrolizumab (Keytruda). Target 20 patients, measure T-cell responses and progression-free survival. Secure FDA Fast Track designation. Partner with a CDMO for GMP mRNA manufacturing. Timeline: 18-24 months, $15M.

Phase 3

+

Step 3 (Growth): Expand the platform to 5 additional 'public neoantigen' targets across colorectal, pancreatic, and glioblastoma. License the neoantigen library and predictive models to 3 pharma partners at $5-10M per deal plus royalties. Use partnership revenue to fund internal pipeline. Build a 50-person team spanning computational biology, immunology, and clinical development. Timeline: 24-36 months, $40M.

Phase 4

+

Step 4 (Moat): Establish the largest experimentally validated neoantigen database in the world (10,000+ antigens across 20 cancer types). Develop proprietary 'Immunogenicity Score' algorithms trained on clinical response data, creating a defensible data moat. Advance lead programs to Phase II/III, targeting FDA approval by year 7-8. Explore acquisition by large pharma (BMS, Merck, Roche) or IPO at $1-2B valuation based on platform value and clinical data.

•

Monetization Strategy

+
Hybrid model: (1) Data/Platform Licensing: $5-10M upfront + 3-5% royalties per pharma partner for access to validated neoantigen libraries and predictive models. Target 5-10 partners by year 5 = $50M+ in non-dilutive capital. (2) Internal Pipeline: Develop 3-5 off-the-shelf mRNA cancer vaccines targeting public neoantigens. Price at $50-100K per patient (vs. $500K for personalized CAR-T), targeting 10,000+ patients per indication. Assume 20% market penetration in KRAS-mutant lung cancer alone = $100-200M annual revenue per product. (3) Acquisition/Exit: Position as the 'neoantigen data company' for acquirers seeking to enhance their immunotherapy pipelines. Comparable exits: Neon ($67M, distressed), Gritstone (struggling), but a successful Phase II dataset could command $500M-1B. The key differentiation: Onco-Forge doesn't sell personalized medicine dreams—it sells validated, scalable, off-the-shelf products with real unit economics.
