AMTEC IIT: Phase 2 Multiarm Study in TNBC

NCT03801369 · Gordon Mills, MD, PhD · PHASE2 · terminated · Breast cancer · Open Targets disease: breast carcinoma · Why it stopped

Six questions a reader deciding whether to spend more time on this asks, each answered with flags: yes, no, or not published (hatched), each with its rule and source record. Flags are never added up into a score or a verdict, because published success rates disagree by a factor of two and more.

1. Is the biology right?

2. Can the result be trusted?

  • Randomised: no · Non-randomised
    Rule: Registry allocation field. Source: ClinicalTrials.gov NCT03801369, 2026-11-11
  • Small denominator: yes · 24 enrolled; each patient moves a rate by 100 ÷ 24 = 4.2 points
    Rule: Enrolment under 30; the arithmetic is shown, not a benchmark. Source: ClinicalTrials.gov NCT03801369, 2026-11-11
  • Primary endpoint is overall survival: no · Objective Response Rate (ORR)
    Rule: A registered primary outcome measure names overall survival. Source: ClinicalTrials.gov NCT03801369, 2026-11-11
    Published context: Non-OS primary endpoint: odds ratio 2.79 for a positive phase 3 (Otsuka 2021, 400 phase 3 oncology trials, to 2020). Shown with the next figure: a surrogate is easier to hit, and often a weak guide to survival.
    Published context: 52% of surrogate-to-OS correlations are low (Prasad 2015, published to 2014). Shown with the figure above.
  • Results overdue: no · Results posted 2025-11-21
    Rule: Primary completion (actual) more than 12 months ago and no results posted to the registry. Source: ClinicalTrials.gov NCT03801369, 2026-11-11

3. What must it beat?

  • Not loaded on this app yet: Control-arm result and approved therapies for the same segment, with label links. Source: Drugs@FDA, FDA labels and readouts (tickets 30, 32).

4. Too crowded, or too late?

  • Stopped on this target: 36 terminated, withdrawn or suspended trials of drugs against AKT2; 7 give no reason. Reasons are quoted as the registry gives them on the target page. · AKT2: what already stopped
  • Not loaded on this app yet: Programs on the target by phase and months behind the leader. Source: Programs and Drugs@FDA (ticket 33).

5. Can it be approved, and stay approved?
