Calgary, Alberta--(Newsfile Corp. - August 31, 2022) - Hemostemix Inc. (TSXV: HEM) (OTCQB: HMTXF) (FSE: 2VF0) ("Hemostemix" or the "Company") received numerous enquiries about the press release of August 30, 2022. This press release details the results in a table format and clarifies a misprint.

Table 1 is a summary of the patients that underwent a trans-catheter, intramyocardial injection of angiogenic cell precursors (ACP-01) as a treatment for heart failure (ischemic and non-ischemic dilated cardiomyopathy). The first column defines the Patient Category; the second column defines the left ventricle ejection fraction before treatment; the third column defines the left ventricle ejection fraction after treatment; the fourth column defines the left ventricle ejection fraction increase (after LVEF% minus before LVEF%); the fifth column defines the percent increase in left ventricle ejection fraction (after LVEF divided by before LVEF); the sixth column defines the p-value; the seventh column describes remarks.

Outcomes:

  1. The percent increase of all patients at an average of 4 months after treatment was 16.08%, p= 0.0011, statistically significant.
  2. The percent increase of all patients at an average of 12 months after treatment was 26.88%, p=0.003, statistically significant.
  3. The percent increase of the ischemic heart failure patients at an average of four months after treatment was 15.38%, p=0.003, statistically significant.
  4. The percent increase of the ischemic heart failure patients at an average of 12 months after treatment was 27.75%, p=0.003, statistically significant.
  5. The percent increase of the non-ischemic heart failure patients at an average of 12 months after treatment was 55.31%, p=0.002, statistically significant.

Table 2 clarifies the treatment and placebo cohorts of the Phase II critical limb ischemia clinical trial.

Subjects randomized but were not treated n (%) 1 (2.1) 0 1 (1.5)
Subject treated n (%) 46 (97.9) 21 (100) 67 (98.5)

Withdrawal from the study n (%) 20 (42.6) 2 (9.5) 22 (32.4)

 

46 Subjects were treated with ACP and 21 Subjects were treated with a Placebo. 27 ACP-01 Subjects and 19 Placebo Subjects completed the study. 20 ACP-01 Subjects and 2 Placebo Subjects withdrew from the study and had no amputations at time of withdrawl. The ACP-01 amputation rate was misprinted as 3 of 41. It should have printed as 3 of 27 (11.1%). The placebo amputation rate was misprinted as 2 of 21. It should have been printed as 2 of 19 (10.5%).

The trial demonstrated that ACP-01 treated patients, as compared to placebo treated patients:

  1. trend toward improvements in ulcer healing at 3 months
  2. trend toward ulcer healing at 6 months
  3. trend toward ulcer healing at the end of study at 12 months, and
  4. trend toward a reduction in pain associated with critical limb ischemia at 12 months.

The clinical trial power analysis required 95 subjects to achieve a statistically significant result. The previous management team, however, truncated the trial to 65 subjects, reducing to 25% the power for the analysis of the study's primary endpoint.

ACP-01 is safe as a treatment of critical limb ischemia. The results of a previous randomized clinical trial were published in Cytotherapy. After 2 years, 2 patients in the control group died and 6 of 8 limbs were lost to amputation. In the ACP treated group, there were no deaths and 7 of 10 limbs were saved from amputation. Based on the unblinded current results and understandings generated from this phase 2 trial design, and based on the two previous published studies, Management is of the opinion that ACP-01 is worthy of an additional properly designed, prospective, blinded, randomized clinical trial, to prove ACP is efficacious as a treatment of critical limb ischemia.
