TSDS | Target-Scoped Decision System
Most targets;
and most molecules against them - should not proceed.
TSDS is a governed target-to-asset decision system for difficult drug discovery programs. It begins with target permission and extends into molecule-level progression, helping teams decide which targets, molecules, and execution paths should proceed, pause, or stop.
Constraint precedes selection. Evidence governs progression.
Failure Begins Before the Molecule Fails

Weak Biology
Biology that can't support durable meaningful impact

FALSE TRACTABILITY
The problem is harder then it appears

MOLECULE DRIFT
Program drift off-intent without clear correction.
TSDS does not select.
IT ELIMINATES
Only what survives constraint and evidence is allowed forward.
TWO CONNECTED DECISION LAYERS
01.
TARGET PERMISSION
- Is the biology credible and compelling?
- Can constraints be survived?
- Is the modality fit-for-purpose?
- Can the outcome be measured?
02.
MOLECULE PROGRESSION
- Which molecules should proceed?
- Which should be held for more data?
- Which should stop now?
- Which require re-baselining?
A Target may earn permission. Individual molecules still have to earn progression.
