Question 1

Statistical evaluation of subject data according to the group they were placed in despite not adhering to the study protocol

Accepted Answer

Intention to treat analysis

Answer

Intention-to-treat (ITT) analysis is a statistical approach in clinical trials where all participants are analyzed in the groups to which they were originally randomized, regardless of whether they completed the intervention or adhered to the protocol. This method preserves the benefits of randomization and provides a more realistic estimate of the treatment effect in real-world settings, minimizing bias.

Question 2

The initial recording of data for a clinical study is called __________ and comprises notes from observations, lab results, and other relevant documents.

Accepted Answer

Source Document

Answer

A source document is the original record of clinical findings, observations, or other activities in a clinical trial. It includes all information, original records, and certified copies of original records of clinical findings, observations, or other activities in a clinical trial necessary for the reconstruction and evaluation of the trial. Examples include hospital records, clinic charts, lab results, and investigator's notes.

Question 3

When an investigator is taking part in a fresh protocol that has been added to the IND
When a fresh researcher is brought into the research

Accepted Answer

In the guidance, the FDA noted that there are two instances when it is necessary for an investigator to complete and sign a new Form FDA 1572:

Answer

Form FDA 1572 is a contract between the investigator and the FDA, outlining the investigator's commitments to conduct the study according to the protocol and regulations. The FDA guidance specifies that a new Form 1572 must be completed and signed when a new investigator is added to the research or when an existing investigator participates in a new protocol that has been added to the Investigational New Drug (IND) application.

Question 4

Analysis of all trial participants who followed procedure and finished the experiment

Accepted Answer

per protocol analysis

Answer

Per-protocol analysis (PPA) includes only those participants who completed the study exactly as planned, adhered to the study protocol, and did not have major protocol deviations. This analysis provides an estimate of the treatment effect under ideal conditions, focusing on participants who fully complied with the intervention. It contrasts with intention-to-treat analysis, which includes all randomized participants.

Question 5

Dosage and safety (Find out how the medicine affects human metabolism and pharmacology).

Accepted Answer

Primary purpose of a phase 1 study?

Answer

The primary purpose of a Phase 1 clinical study is to evaluate the safety of a new drug, determine a safe dosage range, and identify potential side effects. These studies also investigate the drug's pharmacokinetics (how the body processes the drug) and pharmacodynamics (how the drug affects the body) in humans. This initial phase helps establish the drug's basic profile in humans.
