Q1.
In a phase III trial, the DSMB observes a significantly higher rate of a rare but serious
adverse event in the experimental arm. The protocol's pre-specified stopping rule for
safety has been met. The DSMB must weigh the potential benefit against the risk.
According to ICH E6(R2) and common ethical guidelines, what is the DSMB's primary
responsibility at this juncture?
A. To unblind the data and make the results B. To recommend termination of the trial if
public immediately the risk outweighs the benefit, regardless of
the pre-specified rules
C. To ensure the safety of trial participants D. To continue the trial to collect more data
and make a recommendation to the sponsor unless the sponsor decides to stop
based on the risk-benefit profile
Correct: C - To ensure the safety of trial participants and make a recommendation to the
sponsor based on the risk-benefit profile
Rationale:The DSMB's primary role is to safeguard the interests of trial participants and
ensure the integrity of the trial. It reviews accumulating data and makes recommendations to
the sponsor, particularly regarding whether the risk-benefit balance remains acceptable.
While pre-specified rules guide decisions, the DSMB must use clinical judgment and ethical
principles to recommend stopping if the risks outweigh the benefits. Unblinding and public
disclosure are not immediate DSMB actions; they would follow sponsor and regulatory
processes. Continuing the trial despite a safety signal would violate the DSMB's duty to
protect participants.
Why the other answers are wrong:
A. Unblinding and public dissemination are not the DSMB's immediate responsibilities; they are
downstream actions after regulatory decisions.
B. The DSMB does not have the authority to terminate a trial unilaterally; it can only
recommend termination to the sponsor.
D. Continuing the trial disregards the DSMB's ethical duty to act on safety signals that meet
stopping rules.

Boards (2018)
Q2.
A biostatistician is analyzing a dataset from a randomized controlled trial. The primary
endpoint is a binary outcome. The protocol specifies a superiority test with a two-sided
alpha of 0.05. The interim analysis is planned after 50% of events. Which of the following
describes the correct interpretation of the O'Brien-Fleming spending function?
Page 3
, Section A - International Trade LAW
A. It uses a constant critical value across all B. It spends most of the alpha early in the
interim analyses to preserve the overall trial, making it easier to stop for efficacy at
Type I error. the first interim.
C. It maintains a very low significance level D. It is a flexible method that does not
at early interim analyses and spends the require pre-specification of the number of
majority of alpha at the final analysis. looks.
Correct: C - It maintains a very low significance level at early interim analyses and spends
the majority of alpha at the final analysis.
Rationale:The O'Brien-Fleming spending function is a conservative group sequential method
that requires a very small p-value to stop early, preserving the overall alpha for the final
analysis. This reduces the chance of prematurely stopping for efficacy while controlling the
Type I error. Constant critical values (A) describe the Pocock method. Spending alpha early
(B) is the opposite of O'Brien-Fleming. The spending function requires pre-specification of
looks (D).
Why the other answers are wrong:
A. Constant critical values are characteristic of the Pocock approach, not O'Brien-Fleming.
B. Spending alpha early describes a more aggressive spending function, not the conservative
O'Brien-Fleming.
D. All alpha-spending functions require pre-specification of the number and timing of interim
analyses to control Type I error.

Clinical Trials, Ch. 3
Q3.
A clinical trial is conducted in a low- and middle-income country. The sponsor is a
multinational pharmaceutical company. The trial is expected to provide a therapeutic
intervention that is not yet available in the host country. Which of the following best
describes the ethical obligation regarding post-trial access as articulated in the
Declaration of Helsinki (2013) and CIOMS guidelines?
A. The sponsor is only required to provide B. The sponsor must make arrangements
post-trial access if the host country has a for post-trial access for all participants who
legal mandate. still need the intervention, and the protocol
should describe these arrangements.
C. Post-trial access is recommended but not D. The host country's government is solely
ethically required if the intervention is not responsible for ensuring post-trial access to
registered in the host country. the intervention.
Correct: B - The sponsor must make arrangements for post-trial access for all participants
who still need the intervention, and the protocol should describe these arrangements.
