Eligibility
Key inclusion criteria
1. Conventional chondrosarcoma, unresectable (=inoperable) or metastatic.

2. Measurable disease by RECISTv1.1. Note: Tumor lesions located in a previously
irradiated (or other locally treated) area will be considered measurable, provided
there has been clear imaging-based progression of the lesions since the time of
treatment.

3. Radiologic progression of disease per RECISTv1.1 criteria within 6 months prior to
screening for this study.

4. Adequate hematologic, coagulation, hepatic and renal function as defined per protocol.

5. Eastern Cooperative Oncology Group performance status (ECOG PS) of 0 or 1.

6. Estimated life expectancy of at least 12 weeks.

7. Availability of archival tissue or fresh cancer biopsy are mandatory.
Minimum age
18 Years
Maximum age
85 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Any prior exposure to DR5 agonists.

2. Allergy or sensitivity to INBRX-109 or known allergies to CHO-produced antibodies.

3. Non-conventional chondrosarcoma, e.g., clear-cell, mesenchymal, extraskeletal myxoid,
myxoid, and dedifferentiated chondrosarcoma.

4. Prior or concurrent malignancies. Exception: Patients with a prior or concurrent
malignancy whose natural history or treatment does not have the potential to interfere
with the safety or efficacy assessments.

5. Chronic liver diseases. Exception: Patients with fatty liver disease are acceptable as
long as adequate hepatic function as defined in the inclusion/exclusion criteria is
confirmed.

6. Evidence or history of multiple sclerosis (MS) or other demyelinating disorders.

7. Other exclusion criteria per protocol.
