The Institute will aim to dramatically disrupt the timeline of cancer treatment, "intercepting" disease when the very first abnormal BRCA1/2 cells develop—or even stopping cancer from developing at all—rather than reducing cancer risk through surgery or treating cancer once it has grown enough to become visible through imaging and testing. The Basser team will pioneer efforts ranging from drugs and immune-based approaches to intercept BRCA-related cancers to new methods of detecting cancer cells with biomarkers and artificial intelligence.

"Over the past 10 years, Basser has become the global epicenter for BRCA research, education, and testing," said Susan Domchek, executive director of the Basser Center for BRCA and the Basser Professor in Oncology in the Perelman School of Medicine at Penn. "We now sit at an inflection point where we have the ability to revolutionize the timeline of cancer care. Mindy and Jon’s gift to create this Institute holds tremendous promise for families who are living with BRCA mutations—and for the broader field of hereditary cancers—where we are so eager to empower patients with options to erase the cancers that have followed their families for generations."

The Grays’ total commitment to Penn over the last decade has now surpassed $125 million, including their transformative $25 million gift that established the Basser Center in 2012 in honor of Mindy’s sister, Faith Basser, who passed away at age 44 of BRCA-related ovarian cancer. Their subsequent gifts have supported advances in BRCA gene mutation-related science around the world and sparked donations to the Basser Center from nearly 5,000 other supporters. In total, the Grays have given over $250 million to philanthropic causes, including maximizing access to education, health care, and other opportunities for low-income children in New York.

Mindy and Jon Gray’s previous gifts establisheded the Basser Center and have supported advances in BRCA gene mutation-related science around the world.
"Mindy and Jon are philanthropic visionaries who give of themselves in many creative ways that have made profound differences in the way we educate, care for, and engage with patients and families who are coping with and at risk of hereditary cancers," said Penn President Liz Magill. "We are so proud to partner with them to transform the outlook for individuals with BRCA mutations and give them better, nonsurgical, options to live healthy, long lives."

"The dream of intercepting these cancers at their earliest stages or preventing them in the first place is no longer science fiction," said Mindy and Jon Gray. "We are thrilled to build on the decade of success at the Basser Center and work towards what should be a transformation in how future generations face these diseases."

Since its establishment as the world’s first center devoted to the study of BRCA-related cancers, Basser physicians, scientists, and genetic counselors have propelled improvements in prevention, screening, and treatment for men and women with BRCA gene mutations. Educational efforts have focused on Latino and Black populations with BRCA mutations, a Jewish outreach campaign reached more than 1,500 synagogues, and a host of virtual programming has engaged and empowered individuals across the world. Today, the Basser Center includes and collaborates with hundreds of professionals from an array of disciplines. The Grays’ latest gift enables the team to focus on a new frontier: cancer interception.

"At Penn Medicine, we are proud to pursue bold, paradigm-changing strategies to improve health and treat and cure disease—this ethos is a common trait among our faculty, staff, and students, and it is brought to life in the most inspiring ways through the generosity of donors such as Mindy and Jon Gray," said J. Larry Jameson, executive vice president of the University of Pennsylvania for the Health System and dean of the Perelman School of Medicine.

Building an interception toolkit
Everyone has BRCA1 and BRCA2 genes, but some people are born with an error, or mutation, in one of these genes. Men and women with either of these inherited gene mutations are at increased risk for certain cancers, including breast, ovarian, prostate, and pancreatic cancers. Today, options for prevention of BRCA-related cancers are largely limited to surgical options such as the removal of healthy breasts and ovaries, both of which can bring significant side effects and tradeoffs. Other patients typically undergo close monitoring, but there are currently no reliable early detection methods for ovarian and pancreatic cancer.

The goal of interception, Domchek says, is to identify and deploy a toolkit of strategies that can be used much like HPV testing for cervical cancer screening and colonoscopies for colon cancer—both tests allow identification of pre-cancerous cells and opportunities to intervene before they develop into disease.

An interception plan for BRCA mutation carriers could potentially include a series of timed interventions designed to keep cancerous cells at bay. In the case of a 25-year-old woman who learns she has a BRCA mutation, for example, future initial care might include close monitoring—with, for instance, "liquid biopsies"—to detect even the most minute amounts of abnormal cells that are on the path to becoming cancer. At age 40, as the risk of cancer increases, her care team could administer a cancer vaccine, "setting back" the biological clock and stopping the growth of precancerous cells. At age 55, doctors could again intercept, perhaps with a drug from the class known as PARP inhibitors, which are already approved for both treatment and recurrence prevention of BRCA-related cancers. At age 70, another interception might be administered, such as preventive radiation or immunotherapy.

Additional pillars of the Cancer Interception Institute’s work will include discovery science leveraging samples in the Basser Biobank and the Gray Foundation Pre-Cancer Atlas to identify the earliest changes associated with BRCA-related cancers and markers to target with prevention and treatment tactics. The team also plans to study pathways associated with these diseases and pinpoint ways to short-circuit abnormal cell growth, and develop new early detection strategies employing AI and new forms of imaging. The Grays’ gift will also support creation of a prevention clinical trials unit for novel studies, including "window of opportunity" trials designed to test safety of drugs prior to risk-reducing mastectomies to identify drugs to be used for prevention.

The reverse stock split is intended to increase the per share trading price of Sonnet’s common stock to satisfy the $1.00 minimum bid price requirement for continued listing on The Nasdaq Capital Market (Rule 5550(a)(2)). Sonnet’s common stock will continue to trade on The Nasdaq Capital Market under the symbol "SONN" and under a new CUSIP number, 83548R204. As a result of the reverse stock split, every fourteen pre-split shares of common stock outstanding will become one share of common stock. The par value of the Company’s common stock will remain unchanged at $0.0001 per share after the reverse stock split. The reverse stock split will not change the authorized number of shares of the Company’s common stock. The reverse stock split will affect all stockholders uniformly and will not alter any stockholder’s percentage interest in the Company’s equity, except to the extent that the reverse stock split results in some stockholders owning a fractional share. No fractional shares will be issued in connection with the reverse split. Stockholders who would otherwise be entitled to receive a fractional share will instead receive a cash payment based on the average closing price of the Company’s common stock on the five (5) consecutive days leading up to the effective date of the reverse split. The reverse split will also apply to common stock issuable upon the exercise of Sonnet’s outstanding warrants and stock options, with a proportionate adjustment to the exercise prices thereof, and under the Company’s equity incentive plans.

The reverse stock split will reduce the number of shares of common stock issued and outstanding from approximately 69.6 million to approximately 5.0 million.

On September 15, 2022, the stockholders of the Company approved the reverse stock split and gave the Company’s board of directors discretionary authority to select a ratio for the split ranging from 1-for-2 to 1-for-40. The board of directors approved the reverse stock split at a ratio of 1-for-14 on September 15, 2022.

Securities Transfer Corporation is acting as the exchange agent and transfer agent for the reverse stock split. Stockholders holding their shares in book-entry form or in brokerage accounts need not take any action in connection with the reverse stock split. Beneficial holders are encouraged to contact their bank, broker or custodian with any procedural questions.

Prestige Biopharma Withdraws Marketing Authorization Application for Herceptin Biosimilar in Europe

On September 16, 2022 Prestige Biopharma Limited, a Singapore-based biopharmaceutical company, reported that the company has withdrawn the Marketing Authorization Application (MAA) for the company’s Herceptin Biosimilar, HD201(Tuznue), submitted to the European Medicines Agency (EMA) (Press release, Prestige BioPharma, SEP 16, 2022, View Source [SID1234619613]). The company will reapply to EMA for the MAA with supplementation of data and analysis.

On May 23, the company requested re-examination on the MAA for the HD201, after receiving a negative opinion from the EMA’s Committee for Medicinal Products for Human Use (CHMP) on May 19. Despite the evidence of the analytical comparability and biological similarity proven through clinical trials of HD201, CHMP delivered a negative opinion due to disparity in the range of acceptance for the criteria of analytical comparability between the clinical testing batch and commercial production batch of HD201.

During re-examination, it was reported that the newly assigned main rapporteur suggested a positive opinion. Nonetheless, it couldn’t overturn CHMP’s range of acceptance for the criteria of analytical comparability. Based on long-term marketing strategy, the company decided to voluntarily withdraw its application and plans to reapply after supplementing data through additional tests and analysis to meet CHMP’s criteria of analytical comparability.

Prestige Biopharma’s HD201 is a proposed biosimilar to Roche’s Herceptin (trastuzumab) and can be prescribed for the treatment of HER2 positive breast and metastatic gastric cancer. Trastuzumab targets human epidermal growth factor 2 (HER2). In some types of cancer cells, HER2 is overexpressed and stimulates the growth of the cancer cells. Trastuzumab works by selectively binding to HER2, thereby stopping the growth of these cancer cells.

Currently, the MAA for HD201 is under review by Health Canada and Korea Ministry of Food and Drug Safety and will be submitted to the US Food and Drug Administration (FDA) by the end of this year. At the same time, Prestige Biopharma plans to focus on the reapplication process of the MAA to EMA for HD201 and prepare for the global market entry based on partnerships with global biopharmaceuticals.
The internal and external expert advisory panel of Prestige Biopharma stated: "The company’s confidence is based on the excellent pharmaceutical quality of HD201 proven through clinical studies and multiple analysis. Through the re-examination, we received positive opinion by the main rapporteur, which is encouraging. We will do our best to obtain approval for HD201 in US and Europe without any doubt and provide patients with better access to treatments."

Earlier this year, ADC Therapeutics announced an exclusive license agreement with Sobi to develop and commercialize ZYNLONTA for all hematologic and solid tumor indications in Europe and select international territories.

The opinion is based on data from LOTIS-2, a large (n=145) Phase 2 multinational, single-arm clinical trial of ZYNLONTA for the treatment of adult patients with relapsed or refractory DLBCL following two or more prior lines of systemic therapy. In April 2021, the U.S. Food and Drug Administration (FDA) granted accelerated approval of ZYNLONTA as the first CD19-targeted antibody drug conjugate (ADC) as a single-agent treatment for adult patients with relapsed or refractory DLBCL after two or more lines of systemic therapy. In September 2021, the European Commission granted Orphan Drug Designation to ZYNLONTA for the treatment of DLBCL.

ADC Therapeutics has an exclusive license agreement with Mitsubishi Tanabe Pharma Corporation (MTPC) for the development and commercialization of ZYNLONTA for all hematologic and solid tumor indications in Japan. In addition, Overland ADCT BioPharma, a joint venture formed by Overland Pharmaceuticals and ADC Therapeutics, is working to develop and commercialize ZYNLONTA in greater China and Singapore. Overland ADCT BioPharma is now conducting a registrational pivotal Phase 2 clinical trial of ZYNLONTA in relapsed or refractory DLBCL in China.

About ZYNLONTA (loncastuximab tesirine-lpyl)

ZYNLONTA is a CD19-directed antibody drug conjugate (ADC). Once bound to a CD19-expressing cell, ZYNLONTA is internalized by the cell, where enzymes release a pyrrolobenzodiazepine (PBD) payload. The potent payload binds to DNA minor groove with little distortion, remaining less visible to DNA repair mechanisms. This ultimately results in cell cycle arrest and tumor cell death.

The U.S. Food and Drug Administration (FDA) has approved ZYNLONTA (loncastuximab tesirine-lpyl) for the treatment of adult patients with relapsed or refractory (r/r) large B-cell lymphoma after two or more lines of systemic therapy, including DLBCL not otherwise specified, DLBCL arising from low-grade lymphoma and also high-grade B-cell lymphoma. The trial included a broad spectrum of heavily pre-treated patients (median three prior lines of therapy) with difficult-to-treat disease, including patients who did not respond to first-line therapy, patients refractory to all prior lines of therapy, patients with double/triple hit genetics and patients who had stem cell transplant and CAR-T therapy prior to their treatment with ZYNLONTA. This indication is approved by the FDA under accelerated approval based on overall response rate and continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.

ZYNLONTA is also being evaluated as a therapeutic option in combination studies in other B-cell malignancies and earlier lines of therapy.
