The Company will also host a virtual investor and analyst event on Monday, September 20, 2021 at 8:30 AM ET, to review the updated Phase 1 data evaluating the investigational combination of UKONIQ (umbralisib) and ublituximab (U2) plus venetoclax presented at iwCLL, as well as provide an overview of the ULTRA-V Phase 2/3 trial.
Michael S. Weiss, the Company’s Chairman and Chief Executive Officer, stated, "We are pleased to see the iwCLL full text abstracts are now available, highlighting updated data from four combination trials including our proprietary U2 doublet regimen. Of particular note, is the updated U2 plus venetoclax Phase 1 data showing among 46 relapsed or refractory CLL patients, an overall response rate of 100% including 35% complete response rate. Additionally, at cycle 12, the data show 88% of evaluable patients achieved undetectable minimal residual disease (uMRD) in the peripheral blood, and 72% uMRD in the bone marrow. These data are encouraging, and we look forward to additional updates at the iwCLL conference as well as reviewing these data and an overview of the ULTRA-V program evaluating the U2 plus venetoclax combination during the virtual event we have planned for Monday, September 20, 2021."

ABOUT U2 PLUS VENETOCLAX PHASE 1 TRIAL
The Phase 1/2 trial, (NCT03379051), is a multi-center, dose-escalation trial designed to assess the safety and efficacy of UKONIQ and ublituximab (U2) plus venetoclax in patients with relapsed or refractory CLL. The primary objective of the trial is to evaluate the safety of venetoclax after U2 induction. The secondary objectives are clinical efficacy as defined by overall response rate (ORR), including complete response (CR) rate, progression-free survival (PFS), and undetectable minimal residual disease (uMRD) rate after 12 cycles of therapy. The trial enrolled approximately 50 CLL patients and is being led by Dr. Paul Barr of the Wilmot Cancer Institute, University of Rochester Medical Center.
ABOUT ULTRA-V PHASE 2 TRIAL
The ULTRA-V Phase 2 trial, (NCT03801525), is an open-label, multicenter, trial designed to investigate the efficacy and safety of UKONIQ and ublituximab (U2) combined with venetoclax in subjects with CLL. The primary endpoint of the trial is overall response rate (ORR) and complete response (CR) rate. The trial enrolled approximately 165 patients with front-line and previously treated CLL at 26 sites throughout the United States.
ABOUT ULTRA-V PHASE 3 TRIAL
The ULTRA-V Phase 3 trial is an open-label, multicenter, randomized controlled clinical trial comparing the time-limited triple combination of UKONIQ and ublituximab (U2) plus venetoclax, to an active control arm of continuous U2. The Phase 3 trial includes two independent randomized cohorts of CLL subjects: a treatment-naïve cohort and a previously treated cohort, with each cohort being enrolled and evaluated independently of each other. The primary endpoint for the trial is progression-free survival (PFS). This trial is being led by Richard R. Furman, MD, Director of CLL Research Center at Weill Cornell Medicine and targeting over 60 U.S. trial sites.
