Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Recommended Phase 2 Dose (RP2D) [ Time Frame: Up to 24 months ]
    The RP2D will be determined using dose limiting toxicities (DLTs) and all other available study data

  2. Maximum Tolerated Dose (MTD) [ Time Frame: Up to 24 months ]
    The MTD will be determined using DLTs

  3. Type, incidence and severity of Adverse Events [ Time Frame: Up to 24 months ]
    Safety and tolerability profile assessed by the Common Terminology Criteria for Adverse Events v5.0


Secondary Outcome Measures :
  1. Overall Response Rate (ORR) according to the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 [ Time Frame: Up to 24 months ]
    Proportion of patients achieving Complete Response (CR) or Partial Response (PR)

  2. Disease Control Rate (DCR) according to the RECIST v1.1 [ Time Frame: Up to 24 months ]
    Proportion of patients achieving CR, PR or Stable Disease (SD)

  3. Progression-free Survival (PFS) [ Time Frame: Up to 24 months ]
    Time from date of start of treatment to date of the first progression or death, whichever occurs first.

  4. Concentration of anti-drug antibodies (ADA) [ Time Frame: Up to 24 months ]
    Immunogenicity profile characterized by concentration of ADAs

  5. Maximum observed concentration (C[max]) [ Time Frame: Up to 24 months ]
    Pharmacokinetic profile characterized by the maximum observed concentration (C[max]) of AMT-116

  6. Area under the curve (AUC) [ Time Frame: Up to 24 months ]
    Pharmacokinetic profile characterized by the area under the curve (AUC) of AMT-116

  7. Terminal half-life (t[1/2]) [ Time Frame: Up to 24 months ]
    Pharmacokinetic profile characterized by the terminal half-life (t[1/2]) of AMT-116

  8. Time to maximum concentration (Tmax) [ Time Frame: Up to 24 months ]
    Pharmacokinetic profile characterized by the time to maximum concentration (Tmax) of AMT-116

  • Patients who have undergone at least one systemic therapy and have radiologically or clinically determined progressive disease during or after most recent line of therapy, and for whom no further standard therapy is available, or who are intolerable to standard therapy.
  • Patients must have at least one measurable lesion as per RECIST version 1.1.
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0-1.
  • Both male and female patients must agree to use effective contraceptive methods.
  • Patients must have adequate organ function.
  • Women of child-bearing potential (WCBP) must have a negative serum pregnancy test.
  • Male patients must agree to use a latex condom, even if they had a successful vasectomy, while on study treatment and for at least 12 weeks after the last dose of the IMP.
  • Male patients must agree not to donate sperm, and female patients must agree not to donate eggs, while on study treatment and for at least 12 weeks after the last dose of the IMP.
  • Availability of tumour tissue sample (either an archival specimen or a fresh biopsy material) at screening.

Key Exclusion Criteria:

  • Prior therapy with ADC based on Top1 inhibitor.
  • Central nervous system (CNS) metastasis.
  • Active or chronic skin disorder requiring systemic therapy.
  • History of Steven's Johnson's syndrome or Toxic Epidermal Necrolysis syndrome.
  • Active ocular conditions requiring treatment or close monitoring, including, but not limited to: macular degeneration, papilledema, active diabetic retinopathy with macular oedema, wet age-related macular degeneration requiring intravitreal injections, or uncontrolled glaucoma.
  • Persistent toxicities from previous systemic anti-neoplastic treatments of Grade >1.
  • Systemic anti-neoplastic therapy within five half-lives or 21 days, whichever is shorter, prior to first dose of the IMP.
  • Radiotherapy to lung field at a total radiation dose of ≥20 Gy within 6 months, wide-field radiotherapy (e.g., > 30% of marrow-bearing bones) within 28 days.
  • Major surgery (not including placement of vascular access device or tumor biopsies) within 28 days prior to the first dose of the IMP, or no recovery from side effects of such intervention.
