Other Events

 

On August 14, 2023, Medicenna Therapeutics Corp. (“Medicenna” or the “Company”) issued a press release announcing certain management changes, including the appointment of Brent Meadows, MBA, as Chief Business Officer (CBO); the departure from the Company of Elizabeth Williams, who had served as Chief Financial Officer; the appointments of Delphine Davan, MSc, MBA, as VP of Investor Relations and Evelyn Pau, PhD, as VP of External Collaborations; and the promotion of Eamonn Peters, CPA, CA to VP of Finance and Minh To, PhD, to VP of Oncology Research.  The press release is furnished as Exhibit 99.1 to this Form 6-K.

 

On August 9, 2023, Medicenna issued a press release providing a clinical update on the monotherapy dose escalation portion of its first-in-human, Phase 1/2 ABILITY Study in patients with advanced solid tumors, as its drug candidate MDNA11, a beta-only, long-acting IL-2 super-agonist, advances to the monotherapy dose expansion phase.  The main objectives of the dose escalation stage of the Phase 1/2 ABILITY study were to evaluate MDNA11’s safety, tolerability, pharmacokinetics and pharmacodynamics (PK/PD), and preliminary anti-tumor activity to inform Recommended Dose for Expansion (RDE) selection in patients with advanced cancers that were refractory to up to 4 different lines of systemic therapy. A total of six dose escalation cohorts (MDNA11 dose ranging from 3mg/Kg to 120 mg/Kg) constituting 20 patients were evaluated, with the majority (75%) having also received at least one line of immunotherapy. 

 

Key findings from the dose escalation portion of the study include:

 

1.Favorable safety profile: MDNA11 was generally well tolerated across cohorts, with the majority of adverse events (AEs) being grade 1 or 2, with no grade 4 or 5 AEs. 

 

2.Promising single-agent activity and durable tumor control: Several patients exhibited encouraging evidence of single-agent activity with tumor control observed in 7 of 19 evaluable patients (37%). 
a.Confirmed partial response to single-agent MDNA11 in a highly aggressive tumor type: A patient in cohort 4 (60mg/kg dose) with metastatic pancreatic ductal adenocarcinoma (PDAC), who had failed to respond to multiple prior systemic therapies, continues to show tumor shrinkage of all metastatic lesions in the liver after each successive scan. The most recent scan, showed an 80% decrease in total tumor size (sum of tumor diameters of the target lesions) with complete regression of 2 out of 3 lesions. This patient continues on study treatment with MDNA11.
b.Prolonged stable disease in metastatic melanoma progressed on prior immune checkpoint inhibition: A patient in cohort 2 (commenced on 10 mg/kg dose and subsequently increased to 30, 60 and 90 mg/kg), having failed prior immunotherapy, experienced stable disease for 84 weeks.

 

3.Pharmacodynamic data on effector anti-tumor immune cells continue to support the mechanistic rationale for MDNA11’s promising anti-tumor activity, with MDNA11 inducing robust expansion of a population of potent activated CD8+T cells and increasing NK cells, but with limited expansion of Tregs which can suppress anti-tumor immunity.

 

4.Based on the totality of the dose escalation data, a RDE of 90 mg/kg given every other week by IV infusion has been chosen for the monotherapy expansion phase of the trial.

 

5.Selection of specific cancers for evaluation in the monotherapy dose expansion phase was determined based on clinical data available from the ABILITY Study, discussions with Medicenna’s Clinical Advisory Board and other expert KOLs, and an understanding of the immunobiology of the selected tumor types and the potential for MDNA11 monotherapy in the post-checkpoint inhibitor setting. The following tumor types will be recruited in the dose expansion phase of the study:
a.Melanoma
b.Non-Melanoma Skin Cancers
c.Microsatellite Instability-High (MSI-H) or deficient DNA mismatch repair (dMMR) cancers. This population was selected to determine if the response achieved in the PDAC patient may have been due to the MSI-H profile. The PDAC patient unequivocally progressed on KeytrudaÒ, which is approved for MSI-H cancers.

 

Medicenna expects to report initial results from ABILITY’s monotherapy dose expansion in the fourth quarter of 2023. Plans are to commence the combination phase of the trial evaluating MDNA11 with Keytruda in the fourth quarter of 2023, with initial results expected in early 2024.  The press release was furnished as Exhibit 99.1 to the Form 6-K filed by the Company on August 9, 2023.

Mr. Meadows brings over 25 years of business development, commercial strategy and marketing experience at large pharma and biotech companies, including Johnson & Johnson, Bristol-Myers Squibb, Shire/Baxalta, and Regeneron, among others.

In this role, Mr. Meadows will be responsible for leadership of Medicenna’s business development and corporate strategy, including structuring, negotiating and executing key alliances and partnerships with Medicenna’s Phase 3 ready glioblastoma (“GBM”) asset, bizaxofusp, and its pipeline of clinical and pre-clinical Superkines. Medicenna's strategic decision to expand its leadership team in Boston represents a significant milestone in the company's growth trajectory.

"On behalf of the Medicenna team, we are thrilled to welcome Brent as our CBO as we build our business development, financing and clinical leadership in Boston,” said Dr. Fahar Merchant, President and CEO of Medicenna. "Brent is an accomplished biopharma leader with an outstanding track record of multiple oncology transactions at both large pharma and biotech companies. By strengthening our executive team with additional C- level appointments in Boston, we look forward to an exciting phase this year and next as we anticipate to reach multiple value inflection milestones with MDNA11’s single-agent and combination dose expansion trials. Brent’s leadership will be key to ensuring that the full potential of bizaxofusp and our Superkine platforms are captured across therapy areas to bring transformative medicines to patients.”

Mr. Meadows said, “I am very excited to join Medicenna’s team to build partnerships and execute transactions with its pipeline of highly differentiated clinical and pre-clinical Superkines, particularly its Phase 3 ready bizaxofusp, which has demonstrated encouraging results in patients with recurrent GBM, a devastating form of brain cancer. Medicenna is founded on transformational science, and I am looking forward to driving the Company's business development strategy as we execute our mission to bring these breakthroughs to more patients in need."

Prior to joining Medicenna, Mr. Meadows served as CBO at OncoOne, where he defined the company's overall business strategy with his cross-functional leadership and oversaw business development, including deal execution. He has also held senior-level positions in business development, commercial strategy and marketing at Regeneron, Bristol Myers Squibb, Biogen and several senior positions at Johnson and Johnson. While at AVEO Oncology and Baxalta/Shire, he led or co-led multiple transactions, each worth over $1 billion. He has an MBA from Babson College and a BSc in Finance from University of Richmond.

In addition, Medicenna is strengthening its investor relations and financial teams with the appointment of Delphine Davan as Vice President of Investor Relations and Communications, and the promotion of Eamonn Peters to Vice President of Finance.
