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.


The study drug, MDNA11, is a selective IL-2 preferentially activating effector T cells (naïve CD8+ T-cells) and NK cells responsible for killing cancer cells, with minimal or no stimulation of the 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 16 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 two parts:

  • Sequential Dose Escalation
  • Dose Expansion in monotherapy as well as with an immune checkpoint inhibitor.

Approximately 100 patients will be enrolled.

Tumor assessment by CT/MRI will be performed every 12 weeks and will continue until documented disease progression. Treatment may continue for up to 1 year, or until treatment discontinuation criteria are met. Patients can withdraw from participation at any time.

Exclusion Criteria

Last administration of prior antitumor therapy or any investigational treatment within 28 days or less than 5 times the half-life, whichever is shorter.

Clinically significant active, known or suspected autoimmune disease, or diseases that can be exacerbated with immunotherapy
Severe pulmonary, cardiac or other systemic disease
Females who are pregnant or lactating or planning to become pregnant during the study
Active infection requiring systemic therapy
Any medical, emotional or psychiatric condition that interfere with the patient's ability to adhere to the protocol
Any other underlying medical conditions that, in the Investigator's opinion, will make the administration of study drug(s) unsafe or obscure the interpretation of toxicity determination or adverse events
Known severe hypersensitivity to any component of study drug(s)
Prior Interleukin therapy
Inability to comply with study and follow up procedures as judged by the Investigator
