Antibody DS-8273a Administered in Combination With Nivolumab in Subjects With Advanced Colorectal Cancer
A Phase 1 Study of TRAIL-R2 (DR5) Antibody DS-8273a Administered in Combination With Nivolumab in Subjects With Advanced Colorectal Cancer
This trial is being performed in two parts: Dose Escalation and Dose Expansion.
The primary objective for the Dose Escalation part is to determine the safety and tolerability at different doses of DS-8273a administered in combination with nivolumab and to identify the dose combination for the Dose Expansion cohort in subjects with mismatch repair (MMR)-proficient advanced colorectal cancer.
The primary objectives for the Dose Expansion part are:
- To further evaluate the safety and tolerability of DS-8273a administered at the selected dose in combination with nivolumab in subjects with MMR-proficient advanced colorectal cancer
- To evaluate preliminary anti-tumor activity of DS-8273a plus nivolumab administered at the selected dose in subjects with MMR-proficient advanced colorectal cancer

- Is MMR-proficient [selected by the site based on microsatellite instability assay (MSI) and/or immunohistochemistry (IHC) for MMR proteins]
- At least 1 measurable lesion per Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1.
- Eastern Cooperative Oncology Group (ECOG) Performance Status 0 or 1
- Peripheral blood MDSC level ≥ 10% of mononuclear cell fraction (assayed at a central laboratory)
- Adequate bone marrow, renal, hepatic, and blood clotting function
- Able to comply with protocol visits and procedures
- Agree to use a highly effective form of contraception or avoid intercourse during and upon completion of the study (women for 23 weeks and men for 31 weeks after the last dose of study drug)

- Are willing to provide available pre-existing diagnostic or resected tumor samples. Providing fresh tumor biopsies are optional for all subjects in Dose Escalation cohorts. In the Dose Expansion cohort, up to 6 subjects may be requested to provide pre- and post-treatment tumor biopsies based on eligibility for the procedure. For those subjects who do not have an MMR status, inclusion in the Dose Escalation and Dose Expansion can be achieved by providing a fresh tumor biopsy for MMR testing.
- Subjects with asthma who require intermittent use of bronchodilators (such as albuterol) will not be excluded from this study. Inhaled steroids and intra-articular steroid injections are permitted in this study.
Exclusion Criteria:
- Active infection or chronic comorbidity that would interfere with therapy
- History of other malignancy(ies), except adequately treated non-melanoma skin cancer, curatively treated in situ disease, or other solid tumors curatively treated, with no evidence of disease for ≥ 3 years.
- History of severe hypersensitivity reactions to other monoclonal antibodies.
- Any active autoimmune disease or a documented history of autoimmune disease, or history of syndrome that requires concomitant use of chronic systemic corticosteroids or other immunosuppressive medications, except for subjects with vitiligo, treated thyroiditis or resolved asthma/atopy.
- Prior therapy with an anti-PD-1, anti-PD-L1, anti-PD-L2, or anti-cytotoxic T-lymphocyte-associated protein-4 (CTLA-4) antibody (or any other antibody targeting T-cell co-stimulation pathways).
- Tested positive for hepatitis B or C serological markers (hepatitis B surface antigen or antibodies to hepatitis C virus) or human immunodeficiency virus.
- Recipient of vaccines within 1 month of or during study drug treatment.
- Requires daily supplemental oxygen.
- Recipient of a stem cell or bone marrow transplant.
- A concomitant medical condition that would increase the risk of toxicity, in the opinion of the Investigator or Sponsor.
Clinically active brain metastases, defined as untreated and symptomatic, or requiring therapy with steroids or anticonvulsants to control associated symptoms.
Subjects with treated brain metastases that are no longer symptomatic and who require no treatment with steroids may be included in the study if they have recovered from the acute toxic effect of radiotherapy. A minimum of 4 weeks must have elapsed between the end of whole brain radiotherapy and study enrollment (2 weeks for stereotactic radiotherapy).
- Unresolved toxicities from previous anticancer therapy, defined as toxicities (other than alopecia) not yet resolved to Grade ≤ 1 or baseline. Subjects with chronic Grade 2 toxicities may be eligible per the discretion of the Investigator after consultation with the Sponsor Medical Monitor or designee (eg, Grade 2 chemotherapy-induced neuropathy).
- Systemic treatment with anticancer therapy, antibody-based therapy, retinoid therapy, or hormonal therapy within 3 weeks before study drug treatment; or treatment with nitrosoureas or mitomycin C within 6 weeks before study drug treatment; or treatment with small-molecule targeted agents within 2 weeks, or 5 half-lives before study drug treatment, whichever is longer.
- Therapeutic radiation therapy or major surgery within 4 weeks before study drug treatment or palliative radiation therapy within 2 weeks before study drug treatment.
- Participation in a therapeutic clinical study within 3 weeks before study drug treatment (for small-molecule targeted agents, this non-participation period is 2 weeks or 5 half-lives, whichever is longer), or current participation in other investigational procedures.
- Pregnant or breastfeeding, or planning to become pregnant.
- Substance abuse or medical conditions such as clinically significant cardiac or pulmonary diseases or psychological conditions, that may, in the opinion of the Investigator, interfere with the subject's participation in the clinical study or evaluation of the clinical study results.
- Life expectancy < 3 months, in the opinion of the Investigator.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
EXPERIMENTAL: DS-8273a + nivolumab
Participants will receive their treatment dose until discontinuation for any reason, or trial completion, within two years
|
Nivolumab will be administered at 240 mg intravenously (IV) once every two weeks (Q2W) over 30 (± 5) minutes (on Days 1 and 15 of each cycle of 28 days).
DS-8273a will be administered [90 (± 15) minutes on Day 1 of Cycle 1, and 60 (± 15) minutes in subsequent infusions] after the end of the nivolumab infusion in ascending doses up to 1200 mg IV Q2W.
The regimen is adjusted based on injection site reactions or adverse events.
Additional dose combinations may be considered based on the assessment of safety, primary pharmacodynamic (PDy) effects, and preliminary anti-tumor activities.

|
A DLT is defined as a study drug-related ≥ Grade 3 Adverse Event (AE) occurring during the first cycle (28 days) of treatment, with specific exceptions for hematologic events, elevations in hepatic function enzymes, and adverse events that are pre-identified as not being DLTs.
|
During the first treatment cycle (28 days)
|
Dose Escalation and Dose Expansion Parts: Number of Participants with Clinically Significant Safety Parameters
Time Frame: 2 years
|
Safety parameters will include adverse events that are serious (SAEs), treatment emergent (TEAEs), dose-limiting toxicities (DLTs), physical examination findings (including Eastern Cooperative Oncology Group [ECOG] Performance Status), vital sign measurements, clinical laboratory parameters (serum chemistry, hematology, and urinalysis), immune-related (ir) adverse events (irAEs), anti-drug antibody (ADA), and electrocardiogram (ECG) parameters.
|
2 years
|
Dose Escalation Part: Maximum Tolerated Dose (MTD)
Time Frame: 2 years
|
The MTD is defined as the highest dose of DS-8273a in combination with the tested dose of nivolumab that results in a DLT in less than one-third of the subjects enrolled at that dose level of at least 6 evaluable subjects.
However, AEs that meet the definition of DLT appearing at later cycles will also be considered for the determination of MTD and selection of the Dose Expansion dose.
If the MTD is not reached at 1200 mg of DS-8273a IV Q2W, this highest tested dose may be selected as the maximum administered dose (MAD).

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Plasma Concentrations of DS-8273a
Time Frame: Before and at the end of the first 3 infusions (Cycle 1 Days 1 and 15, and Cycle 2 Day 1), a single time point on Cycle 1 Day 8, then every 16 weeks on the same days as ADA sample analysis, and at the last Visit (if not collected within prior 16 weeks)
|
The plasma concentrations of DS-8273a may be used to assess the exposure levels and for population pharmacokinetic (PK) analysis, if feasible, but no PK parameters will be calculated from the concentrations collected from this study due to sparse sampling time points.
