Brief description of study
What is the purpose of this study?
- Part 1: A first-in-human, open-label, Phase I dose escalation study of DSP107 monotherapy and combination therapy with atezolizumab in patients with advanced solid tumors.
- Part 2: Preliminary efficacy assessment of DSP107 in combination with atezolizumab in second or third line treatment of non small cell lung cancer. Preliminary efficacy assessment of DSP107 as a single agent or in combination with atezolizumab in third line treatment of colorectal cancer.
THIS STUDY IS ENROLLING BY INVITATION ONLY - Consistent with most oncology trials, patients are not actively “recruited,” but are screened by their physician for appropriate clinical trial(s) at the time of their routine clinic visit. Occasionally, a patient may be a self-referral or physician referral, but are still screened for appropriate clinical trials at the time of their routine clinic visit. PI and staff may send copies of relevant consent forms to these patients to look over prior to actually consenting or enrolling them. This may take place at the patient's visit at which the consent is presented or the patient's next visit to the outpatient hematology/oncology clinic.

Detailed description of study
What will happen during the study?
This study will be the first time that DSP107 is administered to human subjects. The aim of
the study is to evaluate the safety, pharmacokinetics (PK), pharmacodynamics (PD) and
preliminary efficacy of DSP107 monotherapy and combination therapy in a two-part design.
Part 1 will involve DSP107 monotherapy dose escalation in subjects with advanced solid tumors
that are not amenable to surgical resection or other approved therapeutic options that have
demonstrated clinical benefit. Additional dose finding cohorts will be enrolled to establish
a safe dose of DSP107 when given in combination with atezolizumab.
Part 2 will comprise two expansion cohorts:
- Expansion cohort A consisting of one treatment arm in which subjects will be treated with DSP107 in combination with atezolizumab. This expansion cohort will enroll subjects with non small cell lung cancer who have progressed following no more than 2 lines of prior systemic treatment including treatment with PD-1 or PD-L1 targeting agents.
- Expansion cohort B consisting of two treatment arms in which subjects will be treated either with DSP107 monotherapy or DSP107 in combination with atezolizumab. This expansion cohort will enroll subjects with colorectal cancer who have progressed following two previous lines of therapy.
Eligibility of study
You may be eligible for this study if you meet the following criteria:
- Conditions: Advanced Solid Tumor, Non Small Cell Lung Cancer, Colorectal Cancer
-
Age: 18 years or above
-
Gender: All
Inclusion Criteria:
- Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1
- Subject must have measurable disease per RECIST version 1.1
- Part 1:
- Histologically confirmed advanced solid tumor that is not amenable to surgical resection or other approved therapeutic options that have demonstrated clinical benefit or subject is intolerant or has refused available therapies
- Part 2, Expansion Cohort A:
- Histologically confirmed, inoperable non-small cell lung cancer (Stage 3b or Stage 4). Squamous and non-squamous histologies are both acceptable
- Wildtype for actionable oncogenic driver mutations (e.g., ALK, EGFR, ROS1, RET, NTRK). Driver mutations for KRAS, BRAF and c-METex14skip will be allowed.
- Received no more than 2 lines of prior systemic treatment, including anti PD-1 or anti PD-L1 therapeutic agent ± chemotherapy. Targeted therapies for KRAS, BRAF and c-METex14skip will not be counted towards the previous lines of therapy.
- Part 2, Expansion Cohort B:
- Histologically confirmed, inoperable microsatellite stable colorectal carcinoma (Stage 3b or Stage 4)

- Previously treatment with CAR-T cells
- Treatment with systemic immunosuppressive medication within 2 weeks prior to first dose of study treatment
- Received live, attenuated vaccine within 4 weeks prior to first dose of study treatment
- Treatment with systemic immunostimulatory agents within 4 weeks prior to first dose of study treatment
- Treatment with atezolizumab, any CD47/SIRPα targeting agent or immune agonists (e.g., anti-CD137, anti-CD40, anti-OX40)
- Known allergy or hypersensitivity to any of the test compounds, materials or contraindication to test product
