A critical disconnect exists in drug development: the decision to start a trial is most influenced by the number of academic publications on a target. However, this metric has no bearing on the trial's likelihood of success. The best predictor of success is actually strong human genetic evidence linking the target to the disease.

In a tight funding environment, a significant portion of startups now secure pharma partnerships *before* their Series A. This pre-validation has become a major draw for VCs, signaling a shift where corporate buy-in is needed to de-risk early-stage science for investors.

Human genetics doesn't just provide a drug target; it often specifies the therapeutic approach required. Discovering a protective loss-of-function mutation immediately tells researchers to develop an inhibitor (like an antibody or siRNA), accelerating the path from target discovery to molecule design.

Pharmaceutical companies like Pfizer have vast amounts of human genetic data (GWAS hits) linked to diseases but struggle to determine which are viable drug targets. Gordian's high-throughput in vivo screening directly tests the causal effects of hundreds of these targets, rapidly identifying the most promising candidates.

The surprising failures of Novartis's and Novo Nordisk's heart drugs, both targeting 'genetically validated' pathways, have debunked the widely held belief that genetic data guarantees clinical success. This forces a fundamental rethink of using genetics to de-risk massive drug development investments.

Gilead has tightened its criteria for advancing projects, demanding a deep mechanistic understanding before committing significant resources. This involves validating the target, understanding its biological impact preclinically, and identifying biomarkers—moving beyond just a promising hypothesis to a de-risked scientific thesis.

A profound capital shift has occurred where both venture investors and large pharma partners focus on clinically validated assets. This moves investment away from riskier, early-stage science, creating a significant funding gap for foundational research and pre-clinical startups.

Unlike tech VC, where revenue and users are key metrics, the fundamental currency for an early-stage biotech investment is clinical data. The entire investment thesis revolves around the efficiency and likelihood of translating a novel biological insight into human clinical validation.

While the industry success rate for drugs entering the clinic is only about 10%, programs with human genetics backing have a 2-3x higher probability of approval. Regeneron reports its success rate is even higher, at four to five times the baseline, due to its strict focus on large-effect genetic signals.
