ClinConnect Summary

This clinical trial is studying a new drug called CRD3874-SI to see how safe it is for people with advanced cancers, specifically sarcoma and Merkel cell carcinoma. The researchers will start by testing different doses of the drug to find the highest amount that causes few or mild side effects. Once they determine the safest dose, they will give that dose to more participants to learn more about the side effects and see if the drug is effective in treating these types of tumors.

To be eligible for this trial, participants must be at least 18 years old and have a confirmed diagnosis of a solid tumor that has not responded to previous treatments or for which no standard treatment is available. They should also be able to provide consent and comply with the requirements of the study, including undergoing some tests and possibly tumor biopsies. Participants can expect regular check-ups and monitoring of their health throughout the trial, and they will be contributing to important research that could help improve treatments for others in the future. It’s important for potential participants to discuss any concerns or questions with their healthcare team before deciding to join the study.

Eligibility criteria

• Inclusion Criteria:
• • Male or female age ≥ 18 years at the time of informed consent.
• • Be capable, willing, and able to provide written informed consent.
• • Be willing to comply with clinical trial instructions and requirements, including tumor biopsies (if feasible and required per protocol).
• • Patients must have a locally advanced or metastatic cancer, a malignant solid tumor that has progressed on at least one line of systemic therapy or for which no standard treatment is available, the participant is intolerant to available treatment, or the participant declined standard of care systemic therapy.
• • In the dose escalation phase study patients must have a histologically or cytologically confirmed malignant solid tumor that has progressed on at least one prior standard of care systemic therapy, where available, or declined standard of care systemic therapy.
• • In the dose expansion phase, must have a histologically or cytologically confirmed antiPD1/PD-L1 undifferentiated pleomorphic sarcoma or myxofibrosarcoma, angiosarcoma, or bone sarcoma or merkel cell carcinoma. Patients with UPS/MFS, angiosarcoma and MCC must have progressed on or be refractory to anti-PD-1/anti-PD-L1 therapy.
• • In the dose escalation phase an upper bound weight limit restriction will be used for dose levels 5 and 6. Hence, patients must weight ≤90kg and ≤70kg in order to be eligible to enroll in dose level 5 and 6 of the dose escalation phase, respectively.
• • Adequate performance status: ECOG 0 or 1/KPS 100-70%.
• • Life expectancy of at least three months after the first CRD3874 infusion, according to the Investigator's opinion

• • In the dose expansion phase , participants must agree to have a pretreatment tumor biopsy for research purposes. Participants in whom biopsy is technically not feasible or in whom the associated procedure would result in unacceptable risk, in the opinion of the Investigator, or patients who do not wish to have a biopsy, archival tissue (most recently procured sample where tissue is available) may be used instead, if available.
• • In the dose expansion phase , participants must agree to on-treatment tumor biopsy for research purposes. Participants in whom biopsy is technically not feasible or in whom would result in unacceptable risk, in the opinion of the Investigator, or patients who do not wish to have a biopsy- may be exempted from the biopsy requirement with discussion with the Principal Investigator .
