A Phase 1/2 Open Label, Dose Escalation and Expansion Study of MDNA11, IL-2 Superkine, Administered Alone or in Combination With Immune Checkpoint Inhibitor in Patients With Advanced Solid Tumors

INTRODUCTION

  • Org Study ID: MDNA11-01
  • Secondary ID: N/A
  • NTC ID: NCT05086692
  • Sponsor: Medicenna Therapeutics, Inc.

BRIEF 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.

DETAILED DESCRIPTION

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.

- Agree to use highly effective contraception methods. WOCBP must agree to use highly effective birth control
Key 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. Palliative radiotherapy given within 28 days prior to the first dose of study drug may be approved on a case-by-case basis in discussion with the Sponsor.

- Has carcinomatous meningitis or leptomeningeal disease; stable CNS metastases permitted based on Medical Monitor review.

- 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.
