Fehlende oder unzureichende Trendanalysen führen zu Fehlbestimmung der Haltbarkeit

Updated: Feb 20261 verified sources

Definition

TGA expects shelf life to be determined on the basis of a "statistical and scientific interpretation" of stability data, with shelf lives justified using trend analysis and real data rather than unsupported extrapolation.[1] Common pitfalls highlighted include applying shelf life based mainly on accelerated studies or misapplying regression analysis.[1] Where trend analysis is overly conservative or not product‑specific, companies may set unnecessarily short shelf lives, driving write‑offs of expired stock and limiting market availability. Conversely, if trends are mis‑analysed and stability issues emerge in the market, the resulting recalls, complaint investigations and batch re‑testing are classic costs of poor quality. In Australia’s Zone IVb conditions, degradation can be more pronounced, so errors in extrapolating from non‑representative conditions or in combining batch data can materially affect shelf‑life decisions. For a product with AUD 10 million annual sales, a 1–3 % inventory loss due to overly conservative shelf life or misjudged trends equates to AUD 100,000–300,000 per year.

Key Findings

Financial Impact: Quantified: LOGIC — 1–3 % of annual product value lost through premature expiry write‑offs or post‑market stability failures; for a product with AUD 10 million Australian sales, ≈ AUD 100,000–300,000 per year.
Frequency: Medium: more likely where trend analysis tools are basic (spreadsheets), statistical expertise is limited, or Australian climatic conditions are not fully reflected.
Root Cause: Inadequate statistical expertise in analysing stability trends; use of generic or global shelf‑life rules not tuned to Australian Zone IVb; reliance on accelerated data; lack of integrated tools that link LIMS data to validated statistical models.

Why This Matters

The Pitch: Pharmaceutical manufacturers in Australia 🇦🇺 lose 1–3 % of annual product value through conservative or incorrect shelf‑life settings caused by weak stability trend analysis. Deploying validated trend analysis tools on LIMS data can recover a large share of these losses.

Nichtkonforme Stabilitätsstudien führen zu TGA-Zurückweisungen und Marktverzögerungen

Quantified: LOGIC — 3–6 months launch delay for a product with AUD 5–20 million expected annual sales in Australia (≈ AUD 1.25–10 million lost or deferred revenue), plus 200–600 extra analyst/QC hours per repeat or extended study (≈ AUD 20,000–60,000 per incident at ~AUD 100/hour).

Manuelle Stabilitätsstudien-Verwaltung verursacht Überstunden und Laborengpässe

Quantified: LOGIC — 300–800 analyst/QC hours per year per Australian manufacturing site spent on manual stability coordination, data collation and rework (≈ AUD 30,000–80,000 at ~AUD 100/hour), plus opportunity cost of delayed other testing activities.
