Brief Summary
This clinical study is testing whether a new combination of medicines (DSP107 and atezolizumab) is more effective and safer than an existing treatment (fruquintinib) for people with advanced colorectal cancer that is microsatellite stable (MSS). Participants will be randomly assigned to receive one of the two treatments, and researchers will monitor how well the cancer responds, how safe the treatments are, and how the body processes them. The study hopes to show that the new combination can improve outcomes for patients with this type of colorectal cancer.

Outcome Measures
Primary Outcomes (1)
To determine Median overall survival (mOS) in participants treated with the combination of DSP107 and atezolizumab versus fruquintinib.
Median Overall Survival (mOS) will be estimated using Kaplan-Meier methodology as the median time from the start of study treatment to the last known date a participant was alive. Censoring rules will be applied for participants without an event at the time of analysis, and 95% confidence intervals for mOS will be provided.
From Day 1 until date of death from any cause assessed up to 2 years
Secondary Outcomes (7)
Incidence and severity of adverse events (AEs)
From Screening to Follow-up (30 to 90 Days Post IP)
Changes in 12-lead ECG parameters
From Baseline through to end of treatment visit, an average of 6 months
Change in Overall Survival (OS)
From randomization through study participation, with survival follow-up for up to 5 years in the DSP107_SFU study.
Change from Baseline in Quality of Life (QoL)
From Baseline through to end of treatment visit, an average of 6 months
Change from Baseline in Systolic and Diastolic Blood Pressure
From Baseline through to end of treatment visit, an average of 6 months
- +2 more secondary outcomes
Study Arms (2)
DSP107 in combination with Atezolizumab
EXPERIMENTALDSP107 10 mg/kg IV on Days 1, 8, and 15 of each 28-day cycle. Atezolizumab 1680 mg IV on Day 1 of each 28-day cycle.
Fruquintinib
ACTIVE COMPARATORParticipants will receive fruquintinib orally in 28-day cycles, for up to 24 cycles (96 weeks), or until disease progression, unacceptable toxicity, or study withdrawal.
Interventions
DSP107 infusion begins \~30 (±10) minutes after completion of atezolizumab infusion on Day 1.
5 mg orally, once daily (with or without food), on Days 1-21 of each 28-day cycle, followed by 7 days off.
Eligibility Criteria
You may qualify if:
- Are ≥ 18 years of age with a life expectancy of \> 3 months.
- Participants with histologically confirmed, inoperable, MSS and/or pMMR CRC which has progressed to, or is intolerant to, specified therapies (and has received prior treatment with no more than 3 lines of therapy).
- Note: Lines of therapy are defined by disease progression between therapies. Participants who discontinue their prior regimen due to toxicity (in the absence of disease recurrence/progression) will also have their prior therapy count as one prior regimen.
- Measurable disease per RECIST v1.1.
You may not qualify if:
- Central nervous system (CNS) metastases unless stable 2 months post definitive therapy with steroids.
- Unresolved AEs of Grade 2 or higher from prior anticancer therapy.
- Past or current history of autoimmune disease or immune deficiency.
- History of other malignancy within 3 years of first study treatment cycle.
- Current or recent treatment with certain therapies including specified anticancer treatments, modulators of CYP3A4 and immunomodulating therapies (prior treatment with CPIs is not exclusory).
- Known allergy or hypersensitivity to any of the test compounds, materials, or contraindication to test product.
- Clinically significant abnormal laboratory safety tests.
