§1Evidence extract: Biological ageing and healthspan endpoints

§1.1Question and anchor outcome

Population
Interventions proposed to modify rate of biological ageing, assessed by composite biomarker clocks, functional measures, or mortality.
Intervention
CJC-1295, subcutaneous
Comparator
As used in each contributing trial; reported per trial rather than pooled across comparator types
Anchor outcome
Epigenetic age acceleration

Additional outcomes the Institute extracts for this indication: Frailty index; Functional capacity; All-cause mortality.

§1.2Contributing trials

No trial has been identified for CJC-1295 in biological ageing and healthspan endpoints. The rating below reflects that absence.

Figure 2. Domain-by-domain certainty assessment for CJC-1295 in biological ageing and healthspan endpoints. The starting rating for a body of randomised evidence is high; each serious concern reduces it by one level and each very serious concern by two.

Table 2. Reasoning recorded against each certainty domain.

DomainRatingReasoning
Risk of biasSeriousAllocation concealment is not described in one contributing report.
InconsistencySeriousToo few contributing studies to assess consistency formally.
IndirectnessNo concernNo serious concern identified in this domain.
ImprecisionSeriousThe confidence interval spans values that would support different decisions.
Publication biasNo concernNo serious concern identified in this domain.
Overall rating: Very low certainty. The Institute has very little confidence in the effect estimate. The true effect is likely to be substantially different from the estimate. In this series a very low rating most often reflects an absence of controlled human evidence rather than conflicting evidence.
