The Notes, which will be issued at 100% of face value, will be senior secured obligations of the Company and will bear interest at a rate of 8.0% per annum, payable semi-annually in equal installments until the maturity date, unless earlier redeemed or repurchased. The Notes will be governed by a trust indenture to be entered into on closing of the Offering (the "Indenture"). The Indenture enables the Company to issue additional notes on an ongoing basis as needed, subject to maintaining leverage ratios and complying with the other terms and conditions of the Indenture. In addition, the Indenture permits up to an additional US$200 million of senior bank financing. Curaleaf intends to use the net proceeds from the Offering to refinance existing indebtedness, for working capital, and to pay transaction fees and expenses. The Notes will mature on December 15, 2026. The Offering is expected to close on December 15, 2021, subject to customary closing conditions.

"We are pleased to announce what we believe is the largest debt financing of any publicly-traded MSO to date," said Joseph Bayern, Chief Executive Officer of Curaleaf. "This offering will allow us to refinance our existing debt at a materially lower interest rate and provides us with additional financial flexibility to execute our strategic growth initiatives. While this initial offering provides more than enough liquidity to refinance our existing debt and meet current needs, the new Indenture provides us a new degree of flexibility to raise debt financing to ensure we have ample liquidity to meet our needs now and into the future."

The talk, entitled BTM-3566, a Novel Activator of the Mitochondrial Stress Response Promotes Robust Therapeutic Responses In Vitro and In Vivo in Diffuse Large B-Cell Lymphoma, was selected by ASH (Free ASH Whitepaper) as part of the session "Lymphoid Neoplasms: Targeting Mitochondrial Survival Pathways." Data presented showed BTM-3566 to be a highly potent activator of mitochondrial integrated stress response (ISR), which is well-tolerated in the pre-clinical setting with favorable pharmacokinetics. BTM-3566 induces rapid cell death in lymphoma cell lines, particularly those from DLBCL patients. In vivo, BTM-3566 was highly active in all patient-derived xenograft (PDX) models of DLBCL, and induced complete tumor regression in six out of eight models including those harboring genomic alterations usually associated with poor prognosis. Regressions were observed in multiple models of double-hit DLBCL.

"DLBCL that has relapsed or is refractory to standard therapy continues to be a challenge and treatments are especially limited for patients who are not candidates for stem cell transplantation or who have failed CAR-T cell therapy," said Adrian Schwarzer, M.D., Ph.D., the presenting author and Resident at the Department of Hematology, Oncology and Stem Cell Transplantation, Hannover Medical School in Hannover, Germany. "We are excited to see how BTM-3566 promoted complete tumor regression in vivo in mouse models with poor prognosis. We believe BTM-3566’s mechanism of action potentially defines a new class of compounds that activate, and regulate, the mitochondrial protease OMA1."

"We are encouraged by these strong results in pre-clinical studies, and pleased that ASH (Free ASH Whitepaper) selected this research for inclusion in its oral session on mitochondrial survival pathways," said Michael Stocum, President and Chief Executive Officer, Bantam Pharmaceuticals. "Importantly, these findings support our IND application in early 2022 and initiating first-in-human clinical trials in the first half of 2022."

PRGN-3006 UltraCAR-T is a multigenic autologous CAR-T simultaneously expressing a CAR specifically targeting CD33; membrane bound IL-15 (mbIL15) for enhanced in vivo expansion and persistence; and a kill switch to conditionally eliminate CAR-T cells for an improved safety profile. CD33 is over-expressed on AML blasts with lesser expression on normal hematopoietic stem cells. PRGN-3006 UltraCAR-T has been granted Orphan Drug Designation in patients with AML by the US Food and Drug Administration (US FDA).

The Phase 1/1b clinical study is designed to enroll in two phases, an initial dose escalation phase followed by a dose expansion phase, to evaluate safety and determine the maximum tolerated dose of PRGN-3006 delivered via intravenous (IV) infusion without lymphodepletion (Cohort 1) or with lymphodepletion (Cohort 2). The study is also evaluating in vivo persistence and anti-tumor activity of PRGN-3006.

Today’s ASH (Free ASH Whitepaper) presentation included data from 15 r/r AML patients treated in the non-lymphodepletion cohort (N=9) and the lymphodepletion cohort (N=6). Patients were heavily pre-treated with a median of 4 (range: 1 to 6) and 3 (range: 1 to 7) prior regimens in the non-lymphodepletion and the lymphodepletion cohorts, respectively. Additionally, 33% and 50% of the patients had failed prior allogeneic hematopoietic stem cell transplant (allo-HSCT) in the non-lymphodepletion and the lymphodepletion cohorts, respectively. All patients received a single infusion of PRGN-3006.

Safety Data
PRGN-3006 was well-tolerated with no dose-limiting toxicities (DLTs) and no neurotoxicity at any dose level. Overall, there was low incidence of adverse events following PRGN-3006 infusion and the most common adverse events were decreased lymphocyte count, anemia and cytokine release syndrome (CRS). More than 70% of treatment emergent adverse events (TEAEs) were either Grade 1 or 2 with only one transient Grade 3 CRS reported (Dose Level 1, Cohort 1), which resolved in less than 24 hours with tocilizumab and dexamethasone. Other cases of CRS were Grade 1 or 2 and required either no intervention or resolved following standard CRS management. No subjects experienced a significant increase in serum IL-15, demonstrating that mbIL15 remains tethered to the UltraCAR-T cells as designed and is not released.

Clinical Activity
Non-lymphodepletion Cohort
Excellent dose-dependent expansion and persistence of PRGN-3006 in peripheral blood and bone marrow was observed following a single infusion, with detection of UltraCAR-T cells in blood for more than 7 months post-infusion highlighting the ability of UltraCAR-T cells to engraft and survive even in the absence of lymphodepletion. Peak expansion was observed between days 7 and 21 in the peripheral blood (FIGURE 1).

In the non-lymphodepletion cohort at the three dose levels evaluated, 3 out of 9 (33%) patients had Stable Disease (SD), per European LeukemiaNet (ELN) criteria, persisting for more than 3 months with one patient experiencing durable SD for more than 7 months with concomitant reduction in peripheral blast levels.

Lymphodepletion Cohort
Excellent dose-dependent expansion and persistence of PRGN-3006 in peripheral blood and bone marrow was observed following a single infusion, with detection of UltraCAR-T cells in blood for more than 3 months post-infusion. Peak expansion was observed between days 14 and 21 in the peripheral blood with higher peak expansion (> 10 fold) observed in the lymphodepletion cohort (FIGURE 2) at the same dose level.

An ORR of 50% (3 out of 6) was reported in the lymphodepletion cohort in patients treated at the two lowest dose levels. This included an ORR of 33% (1 out of 3) at Dose Level 1 and 67% (2 out of 3) at Dose Level 2 as summarized in TABLE 1. One responder (Dose Level 1) subsequently received allo-HSCT with ongoing survival greater than 1 year.

Analysis of peripheral blood samples post PRGN-3006 infusion showed gene expression changes consistent with improvement in the immune compartment function for anti-tumor effect in responders. There was an increase in cytotoxicity, costimulatory signaling, and lymphoid compartment and decreased apoptosis pathway scores in the lymphodepletion cohort on Days 14 and 28 post PRGN-3006 treatment compared to baseline.

The study is anticipated to progress to the multicenter expansion phase with the plan to evaluate the potential of repeated dosing of PRGN-3006.

"The interim data for PRGN-3006 showed excellent, dose-dependent expansion and persistence of PRGN-3006 in peripheral blood and bone marrow following a single infusion, with detection of UltraCAR-T cells in blood more than 3 months post-infusion in the non-lymphodepletion and lymphodepletion cohorts," said David A. Sallman, MD, of Moffitt and lead investigator for the PRGN-3006 clinical study. "An ORR of 50% in patients treated at the two lowest dose levels in the lymphodepletion cohort is highly encouraging and the specifics of the responding patients suggest the potential for PRGN-3006 as a bridge to allo-HSCT, which is a very important potential treatment pathway for these patients."

"We are excited by these interim data, which clearly highlight the extraordinary potential and flexibility of the UltraCAR-T platform to deliver precision medicine to patients at any time, at any place and as many times as needed," said Helen Sabzevari, PhD, President and CEO of Precigen. "Based on the favorable safety profile and excellent expansion observed for both the lymphodepletion and the non-lymphodepletion cohorts, we believe UltraCAR-T cells have the potential to improve outcomes for cancer patients."

The CIBI376A201 study is a multi-center, single-arm, open-label pivotal Phase 2 study conducted in China evaluating parsaclisib as a treatment for patients with relapsed or refractory follicular lymphoma. The primary endpoint is objective response rate (ORR) as assessed by independent review committee (IRC); duration of response (DOR), progression-free survival (PFS), overall survival (OS), safety and tolerability are among the secondary endpoints as assessed by investigators.

Eligible patients received parsaclisib 20 mg once daily for eight weeks followed by 2.5 mg once daily, till disease progression or intolerable adverse events. By the data cut-off date, 36 patients were enrolled, of which 24 were evaluable.

Key results of this study are: In 24 evaluable patients with r/r FL, ORR is 91.7% (95%CI : 73%, 99%), Complete Response(CR) is 16.7%, and Partial Response (PR) is 75%. As the results showed, parsaclisib was generally well tolerated with a manageable safety profile.

"We are glad that the data from study CIBI376A201 appears promising, which indicates the potential of parsaclisib to become a clinically valuable treatment for patients with relapsed or refractory follicular lymphoma," said Dr. Hui Zhou, Vice President of Innovent, "We hope the results of this study may potentially provide a new treatment option and help benefit those patients in China."

The leading PI of the study, Dr. Weili Zhao of Shanghai Jiaotong University Ruijin Hospital, stated "The interim analysis shows good response and a tolerable safety profile of parsaclisib in FL patients. We look forward to more exciting results to be revealed with the potential for parsaclisib to be a new effective treatment option for doctors to tackle relapsed or refractory follicular lymphoma."

About Follicular Lymphoma

Follicular lymphoma is a B-cell cancer that originates from the uncontrolled division of specific types of B-cells known as centrocytes and centroblasts. Although it is classified as indolent lymphoma, and the current immunochemotherapy has achieved good efficacy, it still often relapses following by aggressive diseases, which may lead to death within 1 to 2 years. There is an unmet medical need for treatment options for recurrent/refractory follicular lymphoma.

About Parsaclisib

Parsaclisib is a potent, highly selective, next-generation investigational novel oral inhibitor of phosphatidylinositol 3-kinase delta (PI3Kδ). It is currently under evaluation as a monotherapy in several ongoing Phase 2 trials as a treatment for non-Hodgkin lymphomas (follicular, marginal zone and mantle cell); and autoimmune hemolytic anemia. Pivotal trials of parsaclisib in combination with ruxolitinib for the treatment of patients with myelofibrosis are underway; and there are plans to initiate a trial to evaluate parsaclisib in combination with tafasitamab for B-cell malignancies.

In December 2018, Innovent and Incyte entered into a strategic collaboration for three clinical-stage product candidates, including parsaclisib (PI3Kδ inhibitor). Under the terms of the agreement, Innovent has received the rights to develop and commercialize parsaclisib and two other assets in Mainland China, Hong Kong, Macau and Taiwan.
