4 Doses of Leronlimab as the standard recommendation -

Why did the FDA not disclose this and in fact mislead? .
I do recall Dr. Lalezari statement as well as Bruce Patterson supporting 4 doses. Seems unfathomable that Cytodyn would not have lobbied for 4 weekly doses in a 4 week study...and all arrows point that they did.
Journal of Translational Autoimmunity Volume 4, 2021, 100097 also highlighted 4 doses.
VANCOUVER, Washington, April 01, 2021 (GLOBE NEWSWIRE) -- CytoDyn Inc. (OTC.QB: CYDY), (“CytoDyn” or the “Company"
, a late-stage biotechnology company developing Vyrologix™ (leronlimab-PRO 140), a CCR5 antagonist with the potential for multiple therapeutic indications, announced today that after several weeks of discussions with the U.S. Food and Drug Administration (“FDA”) and analysis of CD12 trial data, and in particular the 82% survival results over placebo after two weeks of leronlimab treatment, with statistically significant p-value of 0.0233, the Company has filed a new protocol to extend treatment to four weeks. The Company will initiate patient enrollment in multiple countries, including Brazil, where there are over 20,000 COVID-19 patients in ICU. CytoDyn believes four weeks of leronlimab treatment to be sufficient to calm the cytokine storm and to have a positive effect on survival rate at 4 weeks and potentially 8 weeks.

Abstract
The number of confirmed cases of infection with SARS-CoV-2, the virus causing Coronavirus disease 2019 (COVID-19), continues to increase and is associated with substantial morbidity and mortality in virtually every country in the world. Although in the long-term mass vaccinations remains the most promising approach to control the pandemic, evidence suggests that new variants of the virus have emerged that may be able to evade the immune responses triggered by current vaccines. Therefore despite the recent approval of a number of SARS-CoV-2 vaccines there remains considerable urgency for effective treatments for COVID-19. Severe-to-critical COVID-19 has been shown to be associated with a dysregulated host immune response to SARS-CoV-2 with elevated levels of C–C chemokine receptor type 5 (CCR5) ligands including chemokine C–C ligands 3, 4, 5, as well as interleukins 6 and 10. Leronlimab, a CCR5-specific humanised IgG4 monoclonal antibody originally developed for the treatment of HIV has been studied for the treatment of COVID-19. In the TEMPEST trial which compared leronlimab to placebo in subjects with mild-to-moderate COVID-19, a post hoc analysis showed that leronlimab led to improvements from baseline in National Early Warning Score 2 (NEWS2) at Day 14 in the sub-set of people with more severe disease. Data has also been released on a further ongoing, randomized, placebo-controlled phase 3 registrational trial of leronlimab in 394 people with severe-to-critical COVID-19. The results show that Day 28 mortality was reduced (P = 0.0319) in the subset of participants receiving leronlimab plus other pre-specified commonly used COVID-19 treatments including dexamethasone administered as part of their standard of care (SOC) compared to participants receiving placebo plus other pre-specified commonly used COVID-19 treatments including dexamethasone as part of their SOC. Several cases have recently been reported demonstrated that treatment with leronlimab restores immune function and achieves clinical improvement in people with critical COVID-19. Here we report on a further case of a critically ill person who was treated with leronlimab. This person had been on extracorporeal membrane oxygenation (ECMO) for an extended period of time before receiving 4 doses of leronlimab. The male subject received his first dose of leronlimab on Day 79 of hospitalization he was weaned off ECMO by Day 84 and discharged from the ECMO intensive care unit on Day 91.
