Summary

This trial is testing a new drug, L-DOS47, combined with an existing chemotherapy drug, doxorubicin, in patients with advanced pancreatic cancer who have already received treatment. The goal is to find a safe dose and see if this combination can effectively fight the cancer. L-DOS47 helps the immune system attack cancer cells, while doxorubicin kills them directly.

Who is the study for?
Adults with advanced pancreatic cancer who've had prior treatment can join. They need normal kidney, liver, and blood function, no serious heart issues or infections, and a life expectancy of at least 3 months. Participants must not be pregnant or nursing and agree to use contraception.
What is being tested?
The trial tests L-DOS47 combined with doxorubicin on patients with advanced pancreatic cancer to check safety, tolerability, and initial effectiveness against tumors measurable by scans.
What are the potential side effects?
Potential side effects may include reactions related to the immune system due to L-DOS47 and heart problems, nausea, hair loss from Doxorubicin. Specific side effects will be monitored closely.

Experimental Treatment
Group I: L-DOS47 + doxorubicinExperimental Treatment2 Interventions
Patients will be recruited into escalating dosing cohorts of 3, 6 and 9 µg/kg of L-DOS47, with a minimum of 3 and a maximum of 6 patients per cohort. A fixed dose of intravenous doxorubicin \[20 mg/m2/week\] will be administered in combination with L-DOS47 across all cohorts.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
L-DOS47 increases the pH within the tumor microenvironment, enhancing the efficacy of chemotherapeutic agents like doxorubicin. Doxorubicin works by intercalating into DNA, inhibiting cancer cell replication. This combination is significant for pancreatic cancer patients as it targets cancer cells more effectively, potentially improving treatment outcomes and allowing for more personalized treatment plans.
