Clinical Trial Outcome Measures

Primary Measures

  • The number of patients with adverse events
    • Time Frame: From time of Informed consent to 30 days post last dose (approximately 1 year).
    • Number of patients with adverse events by system organ class and preferred term
  • The number of patients with serious adverse events
    • Time Frame: From time of Informed consent to 30 days post last dose (approximately 1 year)
    • Number of patients with serious adverse events by system organ class and preferred term
  • The number of patients with dose-limiting toxicity (DLT), as defined in the protocol.
    • Time Frame: From first dose of study treatment until the end of Cycle 1 (approximately 21 days).
    • A DLT is defined as any toxicity that occurs from the first dose of study treatment up to and including the planned end of Cycle 1 (the DLT assessment period) that is assessed as unrelated to the disease or disease-related processes under investigation and which includes pre-defined haematological and non-haematological toxicities.
  • The number of patients with changes from baseline laboratory findings, ECGs and vital signs
    • Time Frame: From time of informed consent to 30 days post last dose (approximately 1 year)
    • Description of laboratory findings and vital signs variables over time including change from baseline.

Secondary Measures

  • Objective Response Rate (ORR)
    • Time Frame: From first dose of AZD8205 to progressive disease or death in the absence of disease progression ( approx. 2 years )
    • The percentage of patients with a confirmed investigator assessed complete or partial response according to response criteria in solid tumours (RECIST 1.1).
  • Duration of response (DoR)
    • Time Frame: From the first documented response to confirmed progressive disease or death ( approx. 2 years )
    • The time from the date of first response until date of disease progression or death in the absence of disease progression.
  • Progression free Survival (PFS)
    • Time Frame: From first dose of AZD8205 to progressive disease or death in the absence of disease progression ( approx. 2 years )
    • The time from first dose until RECIST 1.1 defined disease progression or cessation of study treatment.
  • Disease Control Rate at 12 weeks (DCR-12)
    • Time Frame: Measured from first dose until progression. For each patient, this is expected to be at 12 weeks
    • Percentage of patients with confirmed CR or PR or having SD maintained for >= 11 weeks from first dose.
  • Overall Survival (OS)
    • Time Frame: From first dose of AZD8205 to death ( approx. 2 years )
    • The time from the date of the first dose of study treatment until death due to any cause.
  • Pharmacokinetics of AZD8205: Area Under the concentration-time curve (AUC)
    • Time Frame: From the first dose of study intervention, at predefined intervals throughout the administration of AZD8205 ( approx 2 years )
    • Area under the plasma concentration-time curve
  • Pharmacokinetics of AZD8205: Maximum plasma concentration of the study drug (Cmax)
    • Time Frame: From the first dose of study intervention, at predefined intervals throughout the administration of AZD8205 ( approx 2 years )
    • Maximum observed plasma concentration of the study drug
  • Pharmacokinetics of AZD8205: Time to maximum plasma concentration of the study drug (T-max)
    • Time Frame: From the first dose of study intervention, at predefined intervals throughout the administration of AZD8205 ( approx 2 years )
    • Time to maximum observed plasma concentration of the study drug
  • Pharmacokinetics of AZD8205: Clearance
    • Time Frame: From the first dose of study intervention, at predefined intervals throughout the administration of AZD8205 ( approx 2 years )
    • A pharmacokinetic measurement of the volume of plasma from which the study drug is completely removed per unit time.
  • Pharmacokinetics of AZD8205: Terminal elimination half-life (t 1/2)
    • Time Frame: From the first dose of study intervention, at predefined intervals throughout the administration of AZD8205 ( approx 2 years )
    • Terminal elimination half life.
  • Immunogenicity of AZD8205.
    • Time Frame: From the first dose of study intervention, at predefined intervals throughout the administration of AZD8205 ( approx 2 years )
