RE:RE:MDNA Medicenna another Canadian cancer fighter.

RE:RE:MDNA Medicenna another Canadian cancer fighter.Yes, I owned MDNA for a few years - while holding TLT at the same time. I finally gave up on MDNA because I figured it would not have any success while I was still alive. I did sell it at a bit of a loss. I still own my TLT and am still hoping I will be on the right side of the grass. As I have said before these do tend to be a young man's sport.

T.MDNA is worth 76M$CAN.  We are more approx. the same (75M$).   And we possibly have a COVID-19 vaccine with the stamp approval of NML!  So it confirms that we are undervalued.




T.MDNA 

-- Tumor control was achieved in four of ten evaluable patients with advanced solid tumors unresponsive to other treatments enrolled in the ABILITY Study’s low and mid-stage dose escalation cohorts

-- Study’s fifth dose-escalation cohort is open for enrollment following a favorable review of safety data from Cohort 4 by the trial’s Safety Review Committee

-- Data featured in an oral presentation taking place at 1:00 PM ET today at the Cytokine Based Drug Development Summit

TORONTO and HOUSTON, July 27, 2022 (GLOBE NEWSWIRE) -- Medicenna Therapeutics Corp. (“Medicenna” or “the Company”) (NASDAQ: MDNA TSX: MDNA), a clinical-stage immunotherapy company, today announced new clinical data on safety, pharmacodynamics and anti-tumor activity from the Phase 1/2 ABILITY study of MDNA11, the Company’s long-acting IL-2 super agonist. The data, which provide preliminary evidence of MDNA11’s single agent anti-cancer activity in patients with advanced solid tumors who have been unresponsive to other treatments, are being featured in an oral presentation taking place at 1:00 PM ET today at the Cytokine Based Drug Development Summit.

“The ABILITY Study’s latest data add to a body of clinical evidence we believe supports our view on MDNA11’s potential as a best in class IL-2 agonist,” said Dr. Fahar Merchant, President and CEO of Medicenna. “Data from the trial’s initial and mid-stage dose escalation cohorts showed signs of tumor control in four of ten evaluable patients with hard to treat cancers such as sarcomas and pancreatic cancer that are also highly resistant to immunotherapies.”

Dr. Merchant continued, “Complementing these early anti-tumor results are pharmacodynamic data that are consistent with MDNA11’s novel ‘beta-only’ mechanism of action and pre-clinical evidence of tumor localization. Treatment with MDNA11 leads to multi-fold increases in anti-cancer immune cells without stimulation of cells that cause immunosuppression and toxicity typically associated with native IL-2 and its ‘alpha-binding' variants. These early findings continue to fuel our optimism for the outcome of the ABILITY Study based on the evolving data as we escalate from 60 µg/kg to the 90 µg/ dose.”

The ABILITY Study’s dose escalation cohorts are evaluating MDNA11 monotherapy administered intravenously once every two weeks to patients with advanced solid tumors. The trial’s first two cohorts evaluated MDNA11 doses ≤ 10 µg/kg. The trial’s third cohort was administered a dose of 30 µg/kg. Patients in the fourth and fifth dose escalation cohorts receive two 30 µg/kg “priming” doses of MDNA11 before stepping up to receive fixed doses of 60 and 90 µg/kg, respectively.

Key data from patients enrolled in the trial’s four initial dose escalation cohorts include:

Demographics:

  • Patients enrolled in the study to date (N=14) have failed up to four lines of prior systemic therapy.
  • 11 of 14 patients have relapsed or did not respond to at least one prior immunotherapy with a checkpoint inhibitor.
  • To date, 10 of the 14 enrolled patients, including two of six patients in Cohort 4 have received at least one post-baseline scan and are evaluable for response to the investigational treatment.

Safety:

  • MDNA11 treatment in Cohort 4 (comprised of two step-up doses of 30 µg/kg followed by fixed doses of 60 µg/kg every 2 weeks) was not associated with any dose-limiting toxicities.
  • The Safety Review Committee has approved dose escalation for Cohort 5 to the 90 µg/kg dose every 2 weeks following two priming doses at 30 µg/kg.
  • Significant increases in eosinophil count from baseline were not observed with MDNA11 treatment. Extremely high eosinophil count is associated with vascular leak syndrome which is a known side effect of high-dose recombinant human IL-2 (Proleukin®)1.

Anti-tumor Activity:

  • Four of ten evaluable patients have achieved tumor control as defined in the study with MDNA11 monotherapy, including two patients at the 10 µg/kg dose (sarcoma and metastatic melanoma), one sarcoma patient at the 30 µg/kg dose and one pancreatic cancer patient in Cohort 4 receiving the 60 µg/kg dose.
  • The first imaging scans in the remaining four patients enrolled at the 60 µg/kg dose are expected in September.

Pharmacodynamics:

  • MDNA11 preferentially expanded anti-cancer NK and CD8+ T cells without stimulating proliferation of pro-tumor Treg cells.
  • MDNA11 treatment potently activated anti-cancer CD8+ T cells as shown by increases in both CD25+ and ICOS+ CD8+ T cells.
  • Unlike IL-2, MDNA11 has not induced increases in ICOS+ Treg cells. ICOS+ Treg cells are highly immunosuppressive and associated with lack of response to high dose IL-2 immunotherapy.2

A copy of the Cytokine Based Drug Development Summit presentation, entitled, “Co-Stimulation of Adaptive and Innate Immune Cells to Achieve Clinical Benefit with MDNA11, a Long-Acting ‘Beta-only’ IL-2 Super-Agonist,” will be posted to the “Events and Presentations” page of Medicenna’s website following its conclusion.
