"We are very pleased with the tremendous progress we continue to make in our four biggest global markets: the US, Europe, the Middle East and North Africa region and China," said Dr. Thomas Cannell, president and chief executive officer of Sesen Bio. "In the US, we continue to work with the FDA as we approach our target PDUFA date, and we are making substantial progress toward launch readiness. We are laser focused on bringing a product to market that we believe will improve patient outcomes while reducing overall healthcare costs to patients globally, and we expect to continue to make progress around the world in the coming months."

US and OUS Regulatory Update

US:

In February 2021, Sesen Bio received notice from the FDA that the BLA for Vicineum was accepted for filing. Along with the acceptance, the Company was granted Priority Review with a target PDUFA date of August 18, 2021 for a decision on the BLA. The FDA also stated that an advisory committee meeting was not currently planned to discuss the BLA.
Europe:

On March 25, 2021, the Company was notified by the European Medicines Agency (EMA) that the Company’s Marketing Authorization Application (MAA) for Vysyneum was found to be valid and that the review procedure had officially started. Sesen Bio submitted the MAA on March 5, 2021, and the Company remains on-track for potential approval of Vysyneum in the EU in early 2022.
On March 31, 2021, the Company received notice from the Committee for Medicinal Products for Human Use (CHMP) of the EMA that the CHMP has conditionally accepted the proprietary brand name Vysyneum for the Company’s product candidate, oportuzumab monatox, in the EU. The Company believes Vysyneum is a brand name with strong marketing potential given its identical pronunciation to the US proprietary brand name Vicineum. Final approval of the Vysyneum brand name is conditional on EMA product approval.
China:

The Investigational New Drug (IND) application for Vicineum for the treatment of BCG-unresponsive NMIBC submitted to the Center for Drug Evaluation (CDE) of the China National Medical Products Administration (NMPA) was approved on March 19, 2021 ahead of the original timeline of April 2021. This approval triggers a $3M milestone payment to the Company, and authorizes Qilu Pharmaceutical, the Company’s partner in China, to conduct the proposed clinical trial to assess the efficacy and safety of Vicineum in China, at the sole cost of Qilu Pharmaceutical. Assuming a successful trial, Qilu Pharmaceutical anticipates submission of the product market application for Vicineum in 2022, with potential approval in China expected in 2023.
Middle East and North Africa (MENA):

The Company continues to work closely with its partner, Hikma Pharmaceuticals, to submit marketing authorization applications for Vicineum in 2021 in four key markets in the region: the Kingdom of Saudi Arabia, Jordan, Morocco and Egypt. These four markets represent a significant opportunity in the MENA region, as Saudi Arabia, Jordan and Morocco have some of the most advanced healthcare systems in the region while Egypt is the second largest economy in Africa. The Company anticipates the first wave of potential country approvals for Vicineum in the MENA region as early as 2022.
Commercial Update

The Company continues to build its commercial organization with key leadership appointments and a partnership with a leading contract sales organization (CSO), Syneos Health, as it prepares for the anticipated commercial launch of Vicineum in the US in 3Q 2021. Sesen Bio has begun to hire key commercial roles and has entered into a partnership with Syneos Health who will provide speed and logistical support in the hiring and deployment of the sales force. The sales force will include 35 sales representatives across four regions to target approximately 2,000 high prescribers of BCG.
First Quarter 2021 Financial Results

Cash Position: Cash, cash equivalents and restricted cash were $110 million as of March 31, 2021, compared to $55.4 million as of December 31, 2020.
R&D Expenses: Research and development expenses for the first quarter of 2021 were $6.1 million compared to $8.9 million for the same period in 2020. The decrease of $2.8 million was due to decreased costs associated with technology transfer and manufacturing ($4.4 million) and lower clinical trial expense as a result of the Company’s Phase 3 VISTA trial winding down ($0.1 million). This was partially offset by increases in professional services in support of the MAA submission to the EMA ($0.9 million), license milestone fees ($0.6 million) and employee-related compensation ($0.2 million).
G&A Expenses: General and administrative expenses for the first quarter of 2021 were $5.3 million compared to $3.4 million for the same period in 2020. The increase of $1.9 million was due primarily to increases in legal fees ($0.7 million), employee-related compensation driven by increased headcount as part of the commercial build ($0.7 million), professional services ($0.3 million), and other increases ($0.2 million).
Net Loss: Net loss was $55.5 million, or $0.35 per share, for the first quarter of 2021, compared to net income of $41.6 million, or $0.31 per basic share and $0.31 per diluted share, for the first quarter of 2020. The change from net income to net loss was attributable primarily to differences in the non-cash change in the fair value of contingent consideration that is recognized in earnings (or loss) for each respective period.

About Vicineum
Vicineum, a locally administered fusion protein, is Sesen Bio’s lead product candidate being developed for the treatment of BCG-unresponsive non-muscle invasive bladder cancer (NMIBC). Vicineum is comprised of a recombinant fusion protein that targets epithelial cell adhesion molecule (EpCAM) antigens on the surface of tumor cells to deliver a potent protein payload, Pseudomonas Exotoxin A. Vicineum is constructed with a stable, genetically engineered peptide tether to ensure the payload remains attached until it is internalized by the cancer cell, which is believed to decrease the risk of toxicity to healthy tissues, thereby improving its safety. In prior clinical trials conducted by Sesen Bio, EpCAM has been shown to be overexpressed in NMIBC cells with minimal to no EpCAM expression observed on normal bladder cells. Sesen Bio is currently in the follow-up stage of a Phase 3 registration trial in the US for the treatment of BCG-unresponsive NMIBC. In February 2021, the FDA accepted for filing the Company’s BLA for Vicineum for the treatment of BCG-unresponsive NMIBC and granted the application Priority Review with a target PDUFA date of August 18, 2021. Additionally, Sesen Bio believes that cancer cell-killing properties of Vicineum promote an anti-tumor immune response that may potentially combine well with immuno-oncology drugs, such as checkpoint inhibitors. For this reason, the activity of Vicineum in BCG-unresponsive NMIBC is also being explored at the US National Cancer Institute in combination with AstraZeneca’s immune checkpoint inhibitor durvalumab.

On May 10, 2021 Mustang Bio, Inc. ("Mustang") (NASDAQ: MBIO), a clinical-stage biopharmaceutical company focused on translating today’s medical breakthroughs in cell and gene therapies into potential cures for hematologic cancers, solid tumors and rare genetic diseases, reported that the U.S. Food and Drug Administration ("FDA") has accepted the Company’s Investigational New Drug ("IND") application to initiate a Phase 1/2 multicenter study to assess the safety, tolerability and efficacy of MB-106, a CD20-targeted CAR T therapy for relapsed or refractory CD20+ B-cell non-Hodgkin lymphoma ("B-NHL") and chronic lymphocytic leukemia ("CLL") (Press release, Mustang Bio, MAY 10, 2021, View Source [SID1234579603]).

MB-106 targets CD20, a commercially validated target on the surface of cancer cells that has lacked a strong CAR T-based clinical focus in the U.S. MB-106 cells express a third-generation CAR derived from a fully human antibody that originated in the Fred Hutchinson Cancer Research Center ("Fred Hutch") laboratories of the late Oliver Press, M.D., Ph.D., and Brian Till, M.D., Associate Professor in the Clinical Research Division. The CAR T therapy was exclusively licensed to Mustang in 2017, and Fred Hutch and Mustang collaborated to develop the cell processing that will be used in the Mustang IND Phase 1/2 clinical trial.

To date, the same vector planned for use in the manufacturing of MB-106 is currently being evaluated in the ongoing Phase 1/2 study sponsored by Fred Hutch, where Mazyar Shadman, M.D., M.P.H., Associate Professor in the Clinical Research Division, is the Principal investigator. Data from this ongoing study were presented by Dr. Shadman at the 62nd Annual American Society of Hematology (ASH) (Free ASH Whitepaper) meeting in 2020 and demonstrated a favorable safety profile, with an 89% overall response rate (ORR; 8/9 patients) and a 44% complete response rate (CR; 4/9 patients).

NHL is one of the most common cancers in the United States, accounting for about 4% of all cancers, and CLL accounts for about one-third of the new cases of leukemia. The American Cancer Society estimates that in the U.S. in 2021 about 81,560 people will be diagnosed NHL and 21,250 with CLL.

Manuel Litchman, M.D., President and Chief Executive Officer of Mustang, said, "We are pleased with the FDA’s acceptance of our IND application for MB-106, which allows us to further advance this CAR T therapy as a potentially safe and effective treatment option for B-NHL and CLL. It is especially gratifying that we were able to achieve this milestone in just 28 days after our IND submission. We are committed to finding better treatment options for patients living with these cancers and look forward to initiating our multicenter, Phase 1/2 clinical trial later this year, with Dr. Shadman as the Study Chair."

On May 10, 2021 IMV Inc. (Nasdaq: IMV; TSX: IMV) ("IMV" or the "Company"), a clinical-stage biopharmaceutical company pioneering a novel class of cancer immunotherapies, reported that its lead compound, maveropepimut-S (DPX-Survivac) will be investigated in patients with hormone receptor positive/HER2-negative (HR+/HER2-) breast cancer. HR+/HER2- tumors represent an unmet clinical need with relatively poor responses to neoadjuvant endocrine treatment1 (Press release, IMV, MAY 10, 2021, View Source [SID1234579602]). This investigator-initiated clinical study will be conducted at the Providence Cancer Institute in Portland, Oregon, and is expected to begin during summer 2021.

"We are excited to launch the next clinical proof of concept study of maveropepimut-S, which has already demonstrated positive clinical benefit in other cancer indications," said Frederic Ors, Chief Executive Officer at IMV. "Through targeted T-cell therapy, we believe maveropepimut-S presents a compelling option for the treatment of breast cancer. Our lead compound has demonstrated to enhance the innate tumor-fighting response which has resulted in efficacy in solid and liquid tumors without significant toxicity."

Kristina H. Young, M.D., Ph.D., Assistant Member, Tumor Microenvironment Lab in the Earle A. Chiles Research Institute, a division of Providence, commented, "Survivin upregulation is strongly associated with a subpopulation of breast cancer patients that are resistant to aromatase inhibitors. We believe that IMV’s survivin-targeted T cell therapy may improve the sensitivity to neoadjuvant aromatase inhibitors and, therefore, holds the potential to overcome resistance to treatment."

This three-arm Phase 1B trial is designed to assess the combination of maveropepimut-S and aromatase inhibitor with/without radiotherapy or cyclophosphamide (CPA) prior to surgery. Across the three arms of this study, IMV’s lead compound will be evaluated in 18 subjects with resectable, non-metastatic HR+/HER2- breast cancer.

The primary objective is to evaluate the safety of neoadjuvant combination of maveropepimut-S with the aromatase inhibitor and with/without radiation, or CPA and immunogenicity in each arm. Survivin-specific T cells in the resected tumor will be evaluated as a secondary objective. Extensive translational studies will be conducted as exploratory analyses to characterize maveropepimut-S’ mechanism of action in the tumor and the tumor’s immune environment.

"Understanding how HR+HER2- breast cancer responds to immunotherapy, particularly prior to surgery, remains an active area of investigation across the world," said Sasha E. Stanton, M.D., Ph.D., Assistant Member, Cancer Immunoprevention Lab at Providence. "Examining the role of this immune therapy targeting Survivin with the aromatase inhibitor letrozole, as well as the addition of radiation and low dose immune modulating chemotherapy, is important to improve neoadjuvant therapy response in these women."

About Maveropepimut-S (DPX-Survivac)

Maveropepimut-S is the lead candidate in IMV’s new class of immunotherapy that generates targeted and sustained cancer cell killing capabilities in vivo. Maveropepimut-S is evaluated in three phase 2 trials: in association with low dose cyclophosphamide (CPA) in advanced, recurrent ovarian cancer, and in combination with Merck’s Keytruda and low dose CPA in hematological and solid cancers (DLBCL, bladder, hepatocellular and MSI-high tumor cancers). Treatment with maveropepimut-S in association with CPA have demonstrated a favorable safety profile across all clinical studies.

Maveropepimut-S, consists of survivin-based peptides formulated in IMV’s proprietary delivery platform (DPX) which is designed to generate a sustained cytotoxic T cell response against cancer cells presenting survivin peptides on their surface.

Survivin, recognized by the National Cancer Institute (NCI) as a promising tumor-associated antigen, is broadly over-expressed in most cancer types, and plays an essential role in antagonizing cell death, supporting tumor-associated angiogenesis, and promoting resistance to chemotherapies. IMV has identified over 20 cancer indications in which survivin can be targeted by maveropepimut-S.

Maveropepimut-S has received Fast Track designation from the FDA as maintenance therapy in advanced ovarian cancer, as well as Orphan Drug designation status from the FDA and the European Medicines Agency (EMA) in the ovarian cancer indication.
