Freedman's 'clinical equipoise' and sliding-scale all-dimensions-considered equipoise'

Area of Science:

• Medical Ethics
• Clinical Trials
• Research Integrity

Background:

• Ethical guidelines require clinical investigators to maintain equipoise (lack of preference for study arms) when enrolling patients.
• Accumulating data in clinical trials can create a discernible trend favoring one treatment, challenging the principle of equipoise before study objectives are met.

Purpose of the Study:

• Critically evaluate Benjamin Freedman's "clinical equipoise" solution to the ethical dilemma faced by investigators in clinical trials.
• Propose a novel framework, "sliding-scale equipoise," to address the justification of subject enrollment in trials.

Main Methods:

• Critical analysis of Benjamin Freedman's arguments on clinical equipoise, differentiating between community vs. individual and clinical vs. theoretical equipoise.
• Development of a new ethical model for clinical trial enrollment based on patient values.

Main Results:

• Benjamin Freedman's "clinical equipoise" model, with its distinctions, does not adequately resolve the ethical dilemma of trial enrollment when data trends emerge.
• The proposed "sliding-scale equipoise" offers a more nuanced approach to determining justified subject enrollment in clinical trials.

Conclusions:

• Freedman's proposed solutions to clinical equipoise are insufficient for guiding ethical decisions in ongoing clinical trials.
• A "sliding-scale equipoise" model, incorporating patient values, provides a more robust ethical framework for clinical trial participation.
