Summary
This is a Phase 1/2, multi-center, open-label, dose-escalation and expansion study to
evaluate safety and tolerability, PK, pharmacodynamic, and early signal of anti-tumor
activity of MDNA11 alone or in combination with a checkpoint inhibitor in patients with
advanced solid tumors.
Objectives
The study drug, MDNA11, long-acting "beta-only" recombinant interleukin-2 (rIL-2). MDNA11
specifically engineered to overcome the shortcomings of rhIL-2 (aldesleukin) by
preferentially activating immune effector cells (CD8+ T- and NK cells) responsible for
killing cancer cells, with minimal or no stimulation of immunosuppressive Tregs. It is
designed to potentially enhance host immune response and fusion to albumin increases the
half-life further avoiding frequent dosing required with rhIL-2.
The study will be conducted at up to 30 clinical sites following regulatory authority and
institutional review board / independent ethics committee (IRB/ IEC) approval and
completion of informed consent. The study will be conducted in multiple parts:
- Monotherapy (MDNA11 alone) dose escalation
- Monotherapy (MDNA11 alone) dose expansion in select tumor types
- Combination (MDNA11 + pembrolizumab) dose escalation
- Combination (MDNA11 + pembrolizumab) dose expansion in select tumor types
Approximately 115 patients will be enrolled.
After commencing treatment (first exposure of MDNA11 alone or MDNA11 + pembrolizumab),
tumor assessment by CT/MRI will be performed every 8 weeks ± 1 week until immune
confirmed progressive disease ("iCPD") by iRECIST, discontinuation of study drug(s),
withdrawal of consent or loss to follow-up. Treatment beyond progression may be permitted
if criteria are met. Patients can withdraw from participation at any time.
Eligibility
- Aged at least 18 years (inclusive at the time of informed consent).

- Life expectancy of = 12 weeks.
- Women of childbearing potential (WOCBP) must have a negative pregnancy test at screening and within 72 hours before the first dose of study drug(s). Women must not be breastfeeding.
- Agree to use highly effective contraception methods. WOCBP must agree to use highly effective birth control. Key

**Clinical trials are research studies that involve people. These studies test new ways to prevent, detect, diagnose, or treat diseases. People who take part in cancer clinical trials have an opportunity to contribute to scientists’ knowledge about cancer and to help in the development of improved cancer treatments. They also receive state-of-the-art care from cancer experts...
