About Jelmyto

Jelmyto (mitomycin) for pyelocalyceal solution, is a drug formulation of mitomycin indicated for the treatment of adult patients with low-grade upper tract urothelial cancer (LG-UTUC). Utilizing the RTGel technology platform, UroGen’s proprietary sustained release, hydrogel-based formulation, Jelmyto is designed to enable longer exposure of urinary tract tissue to mitomycin, thereby enabling the treatment of tumors by non-surgical means. Jelmyto is delivered to patients using standard ureteral catheters or nephrostomy tube. The U.S. FDA previously granted Orphan Drug, Fast Track, and Breakthrough Therapy Designations to Jelmyto for the treatment of LG-UTUC. On April 15, 2020, the FDA approved Jelmyto, making it the first drug approved for the treatment of LG-UTUC in adult patients.

APPROVED USE FOR JELMYTO

JELMYTO is a prescription medicine used to treat adults with a type of cancer of the lining of the upper urinary tract including the kidney called low-grade Upper Tract Urothelial Cancer (LG-UTUC).

About Upper Tract Urothelial Cancer (UTUC)

Urothelial cancer is the ninth most common cancer globally and the eighth most lethal neoplasm in men in the U.S. Between five percent and ten percent of primary urothelial cancers originate in the ureter or renal pelvis and are collectively referred to as upper tract urothelial cancers (UTUC). In the U.S., there are approximately 6,000 – 7,000 new or recurrent low-grade UTUC patients annually. Most cases are diagnosed in patients over 70 years old, and these older patients often face comorbidities. There are limited treatment options for UTUC, with the most common being endoscopic surgery or nephroureterectomy (removal of the entire kidney and ureter). These treatments can lead to a high rate of recurrence and relapse.

Vor Biopharma Announces Exclusive License of Clinical-Stage CD33 CAR-T from National Cancer Institute

On November 11, 2020 Vor Biopharma, an oncology company pioneering engineered hematopoietic stem cells (eHSCs) for the treatment of cancer, reported an exclusive licensing agreement with the National Cancer Institute (NCI), part of the National Institutes of Health (NIH), for intellectual property related to a clinical-stage anti-CD33 chimeric antigen receptor T-cell (CAR-T) therapy candidate (Press release, Vor BioPharma, NOV 11, 2020, View Source [SID1234570672]). This CAR-T construct was devised by T-cell expert Dr. Terry Fry during his tenure at the Pediatric Oncology Branch of the NCI, where he oversaw development of this therapeutic candidate from bench to bedside; it is currently being evaluated in a multi-site Phase 1/2 clinical trial in children and young adults with relapsed or refractory acute myeloid leukemia (AML).

"As a class, CAR-T cell therapies have had a major positive impact on the lives of certain patients with hematological malignancies. But because normal cells often express the same surface proteins as cancer cells, the utility and applicability of targeted therapies has been limited, in part, by on-target toxicity," said Christopher Slapak, MD, Vor’s Chief Medical Officer. "This agreement provides Vor with access to a promising CD33 CAR-T that could potentially be administered either as bridge-to-transplant therapy for relapsed or refractory patients with AML, or following transplant with our lead developmental candidate VOR33, whereby the CAR-T may selectively target leukemia cells while sparing normal myeloid cells."

Vor’s lead program VOR33, which is currently in pre-clinical development, consists of eHSCs that are engineered to provide AML patients with a donor-derived hematopoietic stem cell transplant that lacks the cell surface protein CD33, a clinically validated target for AML. The goal of removing this target is to make these eHSCs and their progeny treatment-resistant to anti-CD33 therapies. As such, Vor believes this CAR-T could be highly complementary to VOR33.

"This licensing agreement with the NCI is an important milestone for Vor, as it brings elements of a more complete AML treatment system under the same roof," said Hilary Eaton, PhD, Vor’s Senior Director of Business Development. "The combination of our next-generation, treatment-resistant eHSCs with companion therapeutics such as this CD33 CAR-T is designed to provide a single company solution for some patients suffering from hematological malignancies, potentially transforming outcomes and shifting the standard of care."

More information about the Phase 1/2 study of this CD33 CAR-T can be found at clinicaltrials.gov.

Other terms of the agreement have not been disclosed.

About VOR33

Vor’s lead product candidate, VOR33, consists of engineered hematopoietic stem cells (eHSCs) that lack the protein CD33. Once these cells are transplanted into a cancer patient, we believe that CD33 will become a far more cancer-specific target, potentially avoiding toxicity to the normal blood and bone marrow associated with CD33-targeted therapies. Vor aims to improve the therapeutic window and effectiveness of CD33-targeted therapies, thereby potentially broadening the clinical benefit to patients suffering from acute myeloid leukemia.

Novocure Receives CE Mark for NovoTTF-100L™ System

Moderna Announces Clinical Updates on Personalized Cancer Vaccine Program

On November 11, 2020 Moderna, Inc., (Nasdaq: MRNA) a biotechnology company pioneering messenger RNA (mRNA) therapeutics and vaccines to create a new generation of transformative medicines for patients, reported that interim data from the expansion cohort of its ongoing Phase 1 study of the Company’s mRNA personalized cancer vaccine (PCV) mRNA-4157 in combination with Merck’s Keytruda1 at The Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper)’s Annual Meeting (SITC 2020) (Press release, Moderna Therapeutics, NOV 11, 2020, View Source [SID1234570670]). The dose expansion cohort included 10 patients with HPV(-) Head and Neck Squamous Cell Carcinoma (HNSCC) and 17 patients with Micro-Satellite Stable Colorectal Cancer (MSS-CRC). The data shared today showed that mRNA-4157 given in combination with Keytruda is well tolerated at all dose levels and produced responses as measured by tumor shrinkage by RECIST 1.1 criteria in HPV(-) HNSCC patients. No responses were observed in the MSS-CRC group of patients.

Tolerability data to date consistently demonstrate that mRNA-4157 is well tolerated. Adverse events are typically low grade and reversible. In the dose expansion cohort, the Overall Response Rate (ORR) in the HPV(-) HNSCC group of patients as measured by RECIST 1.1 is 50% (5/10) with two patients achieving a complete response (CR) with no detectable disease, and three patients achieving partial response (PR), all of which are ongoing. Median progression free survival (mPFS) is 9.8 months, which compares favorably to the published ORR and mPFS of 14.6% and 2.0 months respectively, for Keytruda monotherapy. Including four patients with stable disease, the Disease Control Rate (DCR) is 90% (9/10). Median duration of response has not been reached. The HPV(-) HNSCC cohort continues to recruit and Moderna has decided to expand the size of the current cohort based on the interim data reported today.

Moderna also announced that Dr. Praveen Aanur has joined Moderna as Vice President, Therapeutic Area Head for Oncology Development. Dr. Aanur joins Moderna from Bristol-Myers Squibb (NYSE: BMY) where he was responsible for multiple regulatory submissions across BMS’ immuno-oncology portfolio. In his seven years at BMS, Dr. Aanur had a wide range of roles increasing responsibility across Clinical Development and Translational Research. Dr. Aanur started his career as a physician and completed his Hematology-Oncology Fellowship at Oregon Health Sciences University, and a Fellowship in Bone Marrow Transplantation at Memorial Sloan Kettering in New York where he was also a clinical investigator in the Bone Marrow Transplant Unit. He holds an MBBS from Bangalore University, an MPH from the University of Alabama, and an MBA from Columbia University School of Business.

"We are encouraged by these interim data from our personalized cancer vaccine program, which involves designing and manufacturing a unique vaccine for each patient based on their specific tumor," said Stephen Hoge, M.D., President of Moderna. "This study demonstrates the ability of Moderna’s mRNA personalized cancer vaccine to elicit clinical activity when given in combination with pembrolizumab. I would also like to welcome Dr. Aanur to Moderna and look forward to working closely with him to continue building our oncology therapeutic area."

About Moderna’s Immuno-Oncology Programs

Moderna’s oncology programs are currently focused on two main areas: cancer vaccines and intratumoral immuno-oncology (I/O) therapies. Moderna is developing these potential mRNA treatments with strategic collaborators Merck and AstraZeneca. The company currently has five I/O programs in development, including two programs in Phase 2 trials.

An advantage of Moderna’s mRNA platform is that it allows for investigational medicines that combine in a single mRNA therapy several different approaches to activate the immune system to attack cancer, either with mRNA encoding for common tumor proteins found across cancer types or multiple mRNAs encoding for various immunomodulatory proteins.

Moderna’s investigational PCVs are designed to use neoantigens identified from an individual’s tumor to program the body’s immune system to elicit a more effective anti-tumor response. Upon sequencing the tumor, Moderna’s proprietary algorithms predict the neoantigens (antigens encoded by tumor-specific mutated genes) most likely to trigger the immune system to attack a particular cancer. Today, mRNA encoding up to 34 unique neoantigens can be delivered in a single vaccine. Moderna develops and manufactures these investigational PCVs at its personalized vaccines unit within its Massachusetts manufacturing facility.

"For the last two months of 2020, we remain focused on enrollment of the Phase 3 trial of lenzilumab for patients hospitalized with COVID-19, in which we recently announced a positive analysis of interim Phase 3 data. As enrollment continues for this trial within the United States and in Brazil, we anticipate applying for an EUA in the first quarter of 2021. I’m pleased with how our team has remained dedicated to advancing promising therapeutics for cytokine storm and would like to thank the dedicated health care providers and essential workers who continue to expose themselves to risk during this pandemic."

Third Quarter 2020 Review and Recent Corporate Updates

Completed an underwritten public offering and uplisted to the Nasdaq Capital Market in September 2020. Humanigen raised net proceeds of approximately $72.7 million from the sale of 9,200,000 shares in the offering, including 1,200,000 shares sold upon the full exercise by the underwriters of their over-allotment option, after deducting the underwriting discounts and commissions and estimated offering costs.
Announced execution of a Cooperative Research and Development Agreement (CRADA) with the Department of Defense (DoD) in support of Operation Warp Speed (OWS) to support the development of lenzilumab as a potential treatment for patients with COVID-19.
Released an interim analysis of blinded data safety monitoring board data from the Phase 3 study suggesting that lenzilumab had a clinically meaningful impact on patient recovery, with an estimated 37 percent more recoveries observed in the lenzilumab arm of the randomized, placebo-controlled, double-blinded study versus current standard of care which includes antivirals and steroids.
Selected to take part in the ACTIV-5 "Big Effect Trial" funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH) to evaluate the combination of lenzilumab and remdesivir on treatment outcomes versus placebo and remdesivir in hospitalized COVID-19 patients. The trial is currently enrolling up to 100 patients in each arm of the study with an interim analysis for efficacy after 50 patients have been enrolled in each arm.
Published a case-control study in the Mayo Clinic Proceedings Journal that demonstrate that an 80% reduction in relative risk of invasive mechanical ventilation (IMV) and/or death for patients treated with lenzilumab compared to the matched control group.
Strengthened our management team with the addition of Dr. Dale Chappell as chief scientific officer, David Tousley as chief accounting and administrative officer, Timothy Morris as chief operating officer and chief financial officer, Bob Atwill as head of Asia-Pacific region and Edward Jordan as chief commercial officer.
Expanded manufacturing capabilities for lenzilumab with supply agreements with Catalent Biologics, Lonza and Thermo Fisher.
Third Quarter 2020 Financial Results

Net loss for the three months ended September 30, 2020 was $30.8 million or $0.71 per share as compared to $2.4 million or $0.11 per share for the third quarter of 2019. The increase in net loss for the quarter was primarily due to an increase in research and development expenses of $21.9 million from $0.5 million for the three months ended September 30, 2019 to $22.4 million for the three months ended September 30, 2020. The increase is primarily due to reservation fees, technology transfer expenses and material manufacturing costs of lenzilumab for the Phase 3 clinical study and in anticipation of filing for an Emergency Use Authorization (EUA) in 2021 and increase in enrollment in the Phase 3 clinical trial related to lenzilumab in hospitalized patients with COVID-19. The increase in the net loss for the third quarter of 2020 was also due an increase in general and administrative expenses of $6.8 million to $8.3 million from $1.5 million for the three months ended September 30, 2019. The increase is primarily due to increased compensation costs including stock based compensation expense related to the hiring of a chief operating and financial officer and a chief commercial officer, an increase in bonus expense upon the completion of certain corporate milestones, and an increase in legal, accounting and public and investor relations expenses in preparation for the listing on Nasdaq including a non-cash charge of $1.9 million for warrants issued to certain consultants which became exercisable upon the completion of the listing on Nasdaq.

Nine months ended September 30, 2020 Financial Results

Net loss for the nine months ended September 30, 2020 was $57.2 million or $1.79 per share as compared to $8.3 million or $0.37 per share for the first nine months of 2019. The increase in net loss for the period was due to an increase in research and development expenses of $42.1 million to $44.2 million from $2.1 million for the nine months ended September 30, 2019. The increase is primarily due to material manufacturing costs of lenzilumab for the Phase 3 clinical study and the initiation in May of 2020 of the Phase 3 clinical trial for lenzilumab in hospitalized patients with COVID-19. The increase in the net loss for the nine months ending September 30, 2020 was also due to an increase in general and administrative expenses of $6.6 million to $11.7 million from $5.1 million for the nine months ended September 30, 2019. The increase is primarily due to increased compensation costs including stock based compensation expense related to the hiring of function heads in the third quarter of 2020 and increased bonus expense upon the completion of certain corporate milestones, and an increase in legal, accounting and public and investor relations expenses in connection with for the listing on Nasdaq.

Cash and cash equivalents

Net cash used in operating activities, net of balance sheet changes, was $23.0 million for the third quarter of 2020. In the third quarter of 2020 the company raised $72.7 million in net proceeds from its underwritten public offering of common stock. As of September 30, 2020, the Company had cash and cash equivalents of $91.4 million.

Expense Guidance for the Fourth quarter and Full Year 2020

We expect our expenses to continue to increase significantly in the remaining three months of 2020 as a result of securing additional manufacturing capacity for the production of lenzilumab, the expansion of enrollment of patients and sites for the clinical trials for COVID-19 and the initiation of commercial preparation activities in anticipation of submitting an EUA in the first quarter of 2021.

"Spending for the third quarter 2020 was higher than consensus due to an increase in manufacturing expenses as we secured additional capacity for lenzilumab to support the clinical trials and prepare for the filing for the EUA early next year. R&D expense may double as we expand the Phase 3 clinical study and continue the production of lenzilumab in the fourth quarter 2020," commented Timothy E. Morris, chief operating and financial officer of Humanigen. "Our current cash balance is sufficient to complete the phase 3 trial and file the EUA. Now that we are part of Operation Warp Speed and following the announcement of the CRADA, we will explore the possibility of financial assistance from the US government to support development of lenzilumab."

A summary of key financial highlights as of and for the periods ended September 30, 2020 and 2019 is as follows ($ in thousands):
