3104NSC Chap.2 Therapeutic Need, Target Discovery and Validation

Therapeutic Need, Target Discovery and Validation

Define therapeutic need

Therapeutic Need, Target Discovery and Validation frames a decision through therapeutic need, target discovery and target validation.

The objective is to compare genetic, biochemical and disease-model evidence before prioritising a target, so the chapter should be read as a chain from problem definition to evidence, option comparison and accountable action.

Start with therapeutic need and name the decision owner, affected stakeholders and time horizon.

The same therapeutic need fact can matter differently across those positions, so the opening frame determines which evidence is relevant.

Use target discovery to explain how the present condition produces an opportunity, cost or risk. A strong target discovery mechanism states what changes, for whom and through which organisational, market or institutional process.

Apply target validation when comparing options.

Keep the target validation criteria distinct, test trade-offs and ask which assumption drives the recommendation. A score or matrix helps only when its criteria are justified by the case.

Drug target validation

In 3104NSC, drug target validation belongs with therapeutic need and target discovery because students use it to compare genetic, biochemical and disease-model evidence before prioritising a target.

A defensible use of drug target validation should define the term, connect it to the case evidence and test the conclusion through target validation; repeating the phrase without that chain does not demonstrate understanding.

Trace target discovery

For the application — compare genetic, biochemical and disease-model evidence before prioritising a target — finish with an actor, action, rationale and review trigger.

This turns the target validation analysis into a recommendation while keeping the decision open to new evidence.

Build a decision ledger. Separate the current condition, the stakeholder affected, the evidence supporting therapeutic need, the mechanism represented by target discovery and the criterion supplied by target validation.

If a target validation recommendation cannot point back to one of those entries, it is probably preference dressed as analysis rather than a consequence of the case.

Compare at least two feasible options against the same criteria. State who benefits under target validation, who bears cost or risk, what capability implementation requires and what evidence would reveal failure.

This comparison is essential when students need to compare genetic, biochemical and disease-model evidence before prioritising a target, because an attractive option is not defensible until its trade-offs are visible.

Rehearse the 3104NSC therapeutic need response as a short briefing: one sentence for the decision, two for the evidence and mechanism, one for the alternative and one for the qualified recommendation.

Then expand only the target discovery move that needs more support. This protects the argument structure under a strict word or time limit.

Test with target validation

A complete response should make the task visible before the detail: identify what must be decided, define the relevant terms, connect the evidence to target discovery, and use target validation to test the result.

The final sentence about target validation should answer the question actually asked rather than merely repeat the topic.

The controlling limit is specific: Association with disease does not by itself demonstrate that modulating the target will be therapeutic.

Keep that target validation limit beside the worked example, because it separates a careful 3104NSC answer from one that sounds confident but claims more than the task or evidence supports.

For revision, retrieve therapeutic need, target discovery and target validation without notes, explain their relationship aloud, then complete a changed version of the application: compare genetic, biochemical and disease-model evidence before prioritising a target.

Record the first failed target discovery reasoning move and repair it before attempting another case.

AskSia practice: apply Therapeutic Need, Target Discovery and Validation

Key terms

therapeutic need

A disease-related outcome insufficiently addressed by existing prevention, diagnosis or treatment options. Use this definition when the task is to compare genetic, biochemical and disease-model evidence before prioritising a target.

target discovery

The identification of a biological molecule or pathway whose modulation may alter a disease-relevant process. Use this definition when the task is to compare genetic, biochemical and disease-model evidence before prioritising a target.

target validation

The accumulation of evidence that changing a proposed target produces the intended biological effect with acceptable relevance and specificity. Use this definition when the task is to compare genetic, biochemical and disease-model evidence before prioritising a target.
