Phase 1
Recruiting
Conditions
Advanced Solid Tumors
Interventions
Registration Number
NCT05800964
Lead Sponsor
Amgen
Brief Summary

The primary objective of this study is to:

* Evaluate the safety and tolerability of AMG 305 in adult participants

* Determine the optimal biologically active dose (OBD), at or below the maximum tolerated dose (MTD) with MTD 1 as the maximum tolerated starting dose and MTD 2 as the maximum tolerated target dose

* Determine the recommended phase 2 dose (RP2D)

Inclusion Criteria
  • Participant has provided informed consent to the main study prior to initiation of any study specific activities/procedures
  • Male or female participants age β‰₯ 18 years
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1
  • Participants with histologically or cytologically documented selected solid tumor diseases. Participants must have exhausted available standard of care (SOC) systemic therapy or must not be candidates for such available therapy
  • For dose expansion cohorts: participants with at least 1 measurable lesion β‰₯10 mm which has not undergone biopsy within 3 months of screening scan. This lesion cannot be biopsied at any time during the study
  • Life expectancy > 3 months
  • Adequate organ function

Key

Exclusion Criteria
  • Untreated central nervous system (CNS) metastases, leptomeningeal disease, or spinal cord compression
  • History of other malignancy within the past 2 years
  • Ongoing or active infection (including chronic or localized)
  • Any pleural effusion or pericardial effusion within 4 weeks or ascites requiring recurrent drainage procedures or other medical intervention within 2 weeks prior to the first dose of the investigational products.
  • Known interstitial lung disease
  • Positive test for human immunodeficiency virus (HIV)
  • Positive hepatitis B surface antigen or positive hepatitis C virus ribonucleic acid (RNA) by polymerase chain reaction (PCR)
  • History of non-infectious/immune-checkpoint inhibitor related pneumonitis that required corticosteroids, or current or suspected pneumonitis that cannot be ruled out by imaging at screening.
  • Anticancer therapies including radiotherapy (with the exception of palliative radiation) chemotherapy or molecularly targeted treatments or tyrosine kinase inhibitors (TKI) within 4 weeks of administration of the first dose of AMG 305; checkpoint inhibitor therapy within 3 months of the first dose of AMG 305; or other immunotherapies/monoclonal antibodies within 3 weeks of administration of the first dose of AMG 305.
  • Has had a major surgery within 4 weeks of administration of a first dose of study treatment
  • Autoimmune disorders requiring chronic systemic steroid therapy or any other form of immunosuppressive therapy while on study (eg, ulcerative colitis, Crohn's disease)
  • Live and/or live-attenuated vaccines received within 28 days (or longer, if required locally) prior to the first dose of AMG 305
  • Participants with unresolved toxicities from prior anti-tumor therapies to Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 grade 1 or better, with the exception of alopecia and grade 2 peripheral neuropathy, which has been unchanged within the last 2 months and there is agreement to allow by both the investigator and sponsor
  • Currently receiving treatment in another investigational device or drug study
  • Female participants of childbearing potential or male participants unwilling to use protocol specified method of contraception
  • Females who are pregnant, breastfeeding or who plan to breastfeed or become pregnant while on study
  • History or evidence of any other clinically significant disorder, condition, or disease (with the exception of those outlined above) that, in the opinion of the investigator or Amgen physician, if consulted, would pose a risk to participant safety or interfere with the study evaluation, procedures or completion

Primary Outcome Measures
NameTimeMethod
Percentage of Participants who Experience Dose Limiting Toxicities (DLTs)Day 1 to Day 28
Percentage of Participants who Experience Treatment-Emergent Adverse Events (TEAEs)Up to a maximum of 2 years

Adverse events (AEs) are defined as any untoward medical occurrence in a clinical study participant irrespective of a causal relationship with the study treatment. TEAEs are any event that occurs after the participant has received study treatment. Any clinically significant changes in vital signs, electrocardiograms (ECGs), and clinical laboratory tests, as assessed by the investigator, will also be reported as TEAEs.

Percentage of Participants who Experience Treatment-Related Adverse EventsUp to a maximum of 2 years
Secondary Outcome Measures
NameTimeMethod
Duration of Response (DOR)Up to a maximum of 2 years

DOR is defined as the time from the first documentation of objective response until the first documentation of disease progression or death due to any cause, whichever occurs first) by RECIST v1.1 and iRECIST.

Time to ProgressionUp to a maximum of 2 years

Time to progression is defined as the time rom first AMG 305 dose until the first documentation of radiological disease progression by RECIST v1.1 and iRECIST.

Minimum Serum Concentration (Cmin) of AMG 305Up to a maximum of 2 years
Area Under the Concentration-Time Curve (AUC) of AMG 305Up to a maximum of 2 years
Progression-Free Survival (PFS)Up to a maximum of 2 years

PFS is defined as the time from first AMG 305 dose until the first documentation of radiologic disease progression or death due to any cause, whichever occurs first) by RECIST v1.1 and iRECIST.

Overall Survival (OS) at 1 Year1 year
Maximum Serum Concentration (Cmax) of AMG 305Up to a maximum of 2 years
Objective Response Rate (ORR) based on Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1)Up to a maximum of 2 years

ORR is defined as best overall response (BOR) of complete response (CR) or partial response (PR), Clinical Benefit Rate (defined as BOR of CR, PR, or stable disease \[SD\] with duration of 24 weeks or longer) based on RECIST v1.1.

OS at 2 Years2 years
ORR based on Immune Response Evaluation Criteria in Solid Tumors (iRECIST)Up to a maximum of 2 years

ORR is defined as immune best overall response (iBOR) of immune complete response (iCR) or immune partial response (iPR), Clinical Benefit Rate (defined as iBOR of iCR, iPR, or immune stable disease \[iSD\] with duration of 24 weeks or longer) based on iRECIST.
