Brief Summary:
This is a Phase I, multi-center, open-label study of ATG-017 administered orally, alone in patients with advanced solid tumors and hematological malignancies. The study design includes a Dose Escalation Phase and Dose Expansion Phase.

Condition or disease Intervention/treatment Phase
Solid Tumor Hematological Malignancy Drug: ATG-017 Phase 1

Detailed Description:
The dose escalation of ATG 017 with intensive safety monitoring to ensure the safety of the patients with solid tumors (solid tumors group) and hematological malignancies (hematological malignancies group) harbouring activating alterations in the RAS-MAPK pathway. Dose Expansion Phase will begin at the defined maximum tolerated dose (MTD) and/or biologically effective dose and/or other dose, in order to further evaluate the safety, tolerability and PDx of ATG 017. Patients with solid tumors or hematological malignancies harbouring activating alterations in the RAS-MAPK pathway will be enrolled.

Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase I, Open-Label, Multi-Center Dose Finding Study to Investigate the Safety, Pharmacokinetics, and Preliminary Efficacy of ATG-017 Monotherapy in Patients With Advanced Solid Tumors and Hematological Malignancies
Actual Study Start Date : August 15, 2020
Estimated Primary Completion Date : May 20, 2023
Estimated Study Completion Date : August 20, 2023

Arm Intervention/treatment
Experimental: ATG-017
ATG-017 will be administered orally on an empty stomach QD in the first cohort of solid tumors group and BID 12 hours apart (no food or drink other than water for 2 hours prior to, and for 1 hour after study treatment administration) in other cohorts. All doses of ATG-017 should be taken at approximately the same time each day. Patients will receive study treatment in 21-day cycles.
Drug: ATG-017
Dosing will begin at 5 mg once a day (QD) ATG-017 as starting dose. A cycle of study treatment will be defined as 21 days.
Other Name: AZD0364 hemi-adipic acid

Primary Outcome Measures :
  1. AEs/SAEs [ Time Frame: 18 months ]
    Toxicity will be graded according to the NCI CTCAE, Version 5.0.

Secondary Outcome Measures :
  1. Plasma concentrations [ Time Frame: 18 months ]
    Venous blood samples for determination of total concentrations of ATG 017 in plasma to characterise the PK profile of ATG-017 for a particular dose level

  2. Overall Response Rate (ORR) [ Time Frame: 18 months ]
    To determine the overall response rate according to RECIST1.1, Chenson 2014, IWG 2003 and 2006

  3. DOR [ Time Frame: 18 months ]
    Duration of time from first occurrence of CR or PR until the first date that disease progression is objectively documented

  4. Progression-Free Survival (PFS) [ Time Frame: 18 months ]
    The time from the first dose date until disease progression or death from any cause

Other Outcome Measures:
  1. Level of phospho-p90RSK [ Time Frame: 18 months ]
    Blood samples will be analysed for the level of phospho-p90RSK

  2. Level of transcript biomarker [ Time Frame: 18 months ]
    Blood samples will be analysed for the level of DUSP6

  3. Level of phospho-ERK [ Time Frame: 18 months ]
    Blood samples will be analysed for the level of phospho-ERK

  4. Level of total ERK [ Time Frame: 18 months ]
    Blood samples will be analysed for the level of total ERK
