Exclusion Criteria

A patient is excluded if any of the following criteria apply:

  • Has not recovered from AEs to at least grade 1 by CTCAE version 5.0 due to prior anti-cancer medications
  • Has symptomatic, steroid-dependent or progressive brain metastasis/metastases
  • Has a history of another primary malignancy, except for: a) Malignancy treated with curative intent and with no known active disease within 2 years prior to first dose of ATOR-1017, b) Adequately treated non-invasive basal skin cancer or squamous cell skin carcinoma, c) Adequately treated uterine cervical cancer stage 1B or less
  • Has an autoimmune disorder requiring immune modulating treatment during the last 2 years
  • Receives treatment with systemic immunosuppressant medication (except for inhaled and low dose systemic corticosteroids, i.e. ≤10 mg prednisolone or equivalent per day)

Primary Outcome Measures
NameTimeMethod
Safety and tolerability: Adverse events (AEs) assessed by Common Terminology Criteria for Adverse Events (CTCAE) v 5.0From start of study until 28 days after last dose

Number of participants with treatment-related AEs assessed by CTCAE v 5.0

Safety and tolerability: Dose-limiting toxicities (DLTs)From first dose of ATOR-1017 (Day 1) until Day 21

Number of participants with DLTs

Secondary Outcome Measures
NameTimeMethod
Pharmacokinetics: Time to CmaxFrom start of study until end of study (28-56 days after last dose)
Pharmacokinetics: Maximum observed serum concentration of ATOR-1017 (Cmax)From start of study until end of study (28-56 days after last dose)
Pharmacokinetics: Area under the ATOR-1017 serum concentration-time curve (AUC)From start of study until end of study (28-56 days after last dose)
Clinical efficacy: Anti-tumor activity assessed by response evaluation criteria in solid tumors for immune-based therapeutics (iRECIST)From start of study until end of study (28-56 days after last dose)

Computed tomography (CT) scans of tumors will be evaluated according to iRECIST

Immunogenicity: Anti-drug antibody (ADA) titer in serumFrom start of study until end of study (28-56 days after last dose)

Levels of antibodies to ATOR-1017 will be evaluated
