running the next trial.
Claidex publishes mechanistic post-mortems on terminated drug programs. Researchers use them to understand what has already failed before committing to the same mechanism.

our impact
The record is growing. So is the signal.
Since launch, Claidex has documented failed programs across oncology, neurology, and immunology — tracing each one back to its preclinical roots.
TERMINATED TRIALS COVERED ACROSS DISEASE AREAS
UNIQUE MECHANISMS ANALYZED
AVERAGE DAYS FROM TERMINATION TO PUBLISHED CLAIM

Real Trials. Real Data.
Every hypothesis has a paper trail.
Each Claim traces the preclinical evidence that justified a trial, then follows it to where the chain broke. Nothing is invented. Every number is sourced.
“We didn’t need a big rollout to prove value. People noticed faster responses and fewer handoffs, and suddenly everyone wanted to be part of it.”

“Once we rolled out Paramount, teams started reaching out on their own. Support became faster, clearer, and easier to work with, and word spread quickly across the company.”

“Paramount helped us bring structure to our support workflows without slowing anyone down. Within weeks, other teams wanted access after seeing how much smoother things ran.”

"We are currently enrolling in CAPItello-292, a Phase III trial testing capivasertib with fulvestrant in HR+/HER2- metastatic breast cancer. Before we opened enrollment, a colleague pointed us to the Claidex post-mortem on alpelisib in TNBC. The AKT and PI3K pathways are adjacent. The failure patterns are documented. That is exactly the kind of signal we want before we commit."

"Before writing the specific aims for a new AKT inhibitor grant, I ran the mechanism through Claidex. Found three terminated programs on the same target class going back to 2018. Two of them failed for reasons that would have been directly relevant to our design. Changed how we framed the primary endpoint."
