Outcome Measures

Primary Outcomes (2)

  • Number of patients with Adverse Events and Serious Adverse Events

    Number of patients with adverse events and with serious adverse events including abnormal clinical observations, abnormal ECG parameters, abnormal laboratory assessments and abnormal vital signs that changed from baseline will be assessed.

    Up to post treatment follow-up (28 days after last dose) [assessed up to 2.3 years]

  • Part A: Number of patients with Dose Limiting Toxicities (DLTs)

    To assess the safety and tolerability of AZD5305 when given in combination with NHA.

    For Arm 1: 35 days, For Arm 2 and 3: 28 days

Secondary Outcomes (22)

  • Area Under the concentration Curve (AUC) of AZD5305

    At the end of Cycle 0 (Cycle 0 is of 7 days)

  • Maximum plasma concentration (Cmax) of AZD5305

    At the end of Cycle 0 (Cycle 0 is of 7 days)

  • Time to maximum concentration (tmax) of AZD5305

    At the end of Cycle 0 (Cycle 0 is of 7 days)

  • AUC of AZD5305

    Arm 1: At Cycle 1 Day 1, Cycle 1 Day 22, Cycle 2 Day 1, Cycle 2 Day 2, Cycle 2 Day 8, and Cycle 3 Day 1; Arm 2 and 3: At Cycle 1 Day 1, Cycle 1 Day 15 and Cycle 2 Day 1 (Each Cycle is of 28 days)

  • Cmax of AZD5305

    Arm 1: At Cycle 1 Day 1, Cycle 1 Day 22, Cycle 2 Day 1, Cycle 2 Day 2, Cycle 2 Day 8, and Cycle 3 Day 1; Arm 2 and 3: At Cycle 1 Day 1, Cycle 1 Day 15 and Cycle 2 Day 1 (Each Cycle is of 28 days)

  • +17 more secondary outcomes
