CytoDyn Reports Continued Positive Clinical Data on its Phase 1b/2 mTNBC and Expanded Access Studies for MBC Ahead of Breakthrough Therapy Designation Decision From the FDA - Seite 2

Patient #6: Injected on 2/8/2020 and the first results since enrollment are due by end of February.

Patient #7: Injected on 2/13/2020.

Patients #8, 9 and 10: Completed screening for enrollment.

“The patients enrolled in the mTNBC Phase 1b/2 trial continue to demonstrate meaningful results that support the hypothesis regarding leronlimab’s mechanism of action,” said Bruce Patterson, M.D., chief executive officer and founder of IncellDx, a diagnostic partner and an advisor to CytoDyn. “In the four patients (1 with MBC, 3 with TNBC) now with results from leronlimab therapy, patients #1-3 have zero CTCs and zero EMTs and Patient #4, who has been treated with leronlimab for 2 weeks showed a decrease of CTCs and EMTs from 8 to 2. New data from Patient #2 with Stage 4 MBC and who has been treated with 10 weekly doses of leronlimab showed zero CTCs and zero EMTs, in addition to the shrinkage or disappearance of some brain metastases as previously reported.”

Nader Pourhassan, Ph.D., president and chief executive officer of CytoDyn, added: “These findings are extremely promising in light of the success rate of other treatment options. Therapeutic options for patients suffering from breast cancer are highly limited and we look forward to continuing enrollment and exploring leronlimab’s potential to treat this devastating disease. Since our basket trial for all solid tumor cancers has been initiated, we are currently screening a prostate cancer patient, and if continued positive clinical results are forthcoming from this patient, we are hopeful that this will clear the path for CytoDyn to file for Breakthrough Therapy designation for all solid tumor cancers. Our mechanism of action is not only focused on the inhibition of metastasis of solid tumor cancers, but also targets the tumor itself through macrophages, angiogenesis and T-reg.”

About Triple-Negative Breast Cancer
Triple-negative breast cancer (TNBC) is a type of breast cancer characterized by the absence of the three most common types of receptors in the cancer tumor known to fuel most breast cancer growth–estrogen receptors (ER), progesterone receptors (PR) and the hormone epidermal growth factor receptor 2 (HER-2) gene. TNBC cancer occurs in about 10 to 20 percent of diagnosed breast cancers and can be more aggressive and more likely to spread and recur. Since the triple-negative tumor cells lack these receptors, common treatments for breast cancer such as hormone therapy and drugs that target estrogen, progesterone, and HER-2 are ineffective.
