Prestige BioPharma’s trastuzumab (HD201) is a proposed biosimilar to Roche’s Herceptin 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.

The license agreement grants Dr. Reddy’s the exclusive rights to commercialize the proposed biosimilar in select countries in Latin America and Southeast Asia. Under this partnership, Prestige BioPharma will be responsible for sustainable commercial supply of HD201 from its manufacturing facilities in Osong, South Korea, while Dr. Reddy’s will be responsible for local registrations, marketing and sales in the licensed territories.

Lisa S. Park, CEO of Prestige BioPharma, commented: "We are delighted to establish a partnership with Dr. Reddy’s for key Latin American and Southeast Asian markets. Dr. Reddy’s is the ideal partner to commercialize our lead biosimilar in these territories. With this collaboration, we look forward to further strengthening the value of our biosimilar programs in global markets."

M.V. Ramana, CEO – Branded Markets (India & Emerging Markets), Dr. Reddy’s, said: "In keeping with our purpose of accelerating access to affordable and innovative medicines, we are happy to bring this life-saving drug to patients in need. Our partnership with Prestige BioPharma will help us combine their established expertise in the area of biosimilars with our commercial strengths and growth ambition in these markets. This is in line with our stated intention to create a portfolio of oncology products and expand our biosimilar offerings in Emerging Markets."

Summary of Clinical Trial Results

The data presented at SABCS are from a clinical study of 24 patients with heavily pretreated HER2-positive metastatic breast cancer who received zanidatamab in combination with either vinorelbine (n=12), capecitabine (n=8), or paclitaxel (n=4). Patients received multiple prior regimens containing HER2-targeted agents including trastuzumab (96%), pertuzumab (96%), and T-DM1 (96%), and many also received a tyrosine kinase inhibitor.

In 22 efficacy-evaluable patients, treatment with zanidatamab and chemotherapy resulted in a cORR of 36.4% and DCR of 86.4%, and the majority of patients experienced a decrease in their tumor size. The mPFS is 7.3 months across all treatment regimens with 42% of patients still on study at the time of data cutoff. Zanidatamab in combination with single agent chemotherapy is well tolerated, with the majority of treatment-related adverse events considered mild to moderate in severity (Grade 1 or 2).

"Zanidatamab together with chemotherapy shows encouraging antitumor activity and a manageable safety profile in patients with HER2‑positive breast cancer that has progressed after treatment with multiple HER2-targeted agents," said Neil Josephson, M.D., Chief Medical Officer at Zymeworks. "We were impressed by the activity and durability of disease control with zanidatamab, with over half of patients experiencing a confirmed response or stable disease lasting over 6 months. These results, together with data presented earlier this year in both HER2‑expressing biliary tract cancer and gastroesophageal adenocarcinoma, build on our belief that zanidatamab has the potential to be a foundational therapy across multiple HER2-expressing solid tumor indications. We look forward to sharing additional data with zanidatamab in HER2‑positive breast cancer from our other ongoing trials in the first half of 2022, including in combination with Ibrance and fulvestrant in late-line hormone receptor positive disease as well as in combination with docetaxel in the first-line setting."

"Zanidatamab continues to generate clinical data that differentiate it from existing and emerging HER2-targeted standards of care," said James Priour, Chief Commercial Officer at Zymeworks. "Expanding on our commitment to complete ongoing pivotal trials in biliary tract and gastric cancers, we see breast cancer as the next indication to pursue a potential label. As we await additional data in early lines of breast cancer, these data in late-line present an additional registrational opportunity. With the majority of HER2-positive breast cancer patients benefitting from new therapies and surviving longer than ever before, there is a significant commercial opportunity in the third- and fourth-line setting. We believe the data presented today demonstrate that zanidatamab and chemotherapy could be a new option for these patients."

Zanidatamab in Combination with Evorpacept (ALX148) – Trial in Progress Poster Presented Today

Title: Zanidatamab (ZW25) in Combination with Evorpacept (ALX148) in Advanced Human Epidermal Growth Factor Receptor 2 (HER2)-expressing Cancers, Including Breast Cancer: a Phase 1b/2, Multicenter, Open-Label, Dose-Finding and Cohort-Expansion Study (ZWI-ZW25-204)
Lead Author: Sara A. Hurvitz, M.D., University of California, Los Angeles; Jonsson Comprehensive Cancer Center, Los Angeles, CA, US
Abstract: #182
Program Number: OT1-14-01

Zymeworks is presenting a trial in progress poster at the SABCS for a Phase 1b/2 multi-center clinical study in HER2-expressing cancers, including breast cancer. This study is evaluating the novel combination of zanidatamab, a HER2-targeted bispecific antibody, and evorpacept, a CD47-blocker, for the treatment of advanced and/or metastatic HER2-positive and HER2-low breast cancer and other HER2-expressing cancers. Treatment with zanidatamab in combination with evorpacept has the potential to augment immune clearance of HER2-expressing cancer cells, by blocking the CD47 signal that inhibits phagocytosis of these cells.

The study is currently open for enrollment. For further information (including updates to active sites), visit www.clinicaltrials.gov [NCT05027139]

About Zanidatamab

Zanidatamab is a bispecific antibody, based on Zymeworks’ Azymetric platform, that can simultaneously bind two non-overlapping epitopes of HER2, known as biparatopic binding. Zanidatamab’s unique binding properties result in multiple mechanisms of action including HER2-receptor clustering, internalization, and downregulation; inhibition of growth factor-dependent and -independent tumor cell proliferation; antibody-dependent cellular cytotoxicity and phagocytosis; and complement-dependent cytotoxicity. Zanidatamab is currently being evaluated in two pivotal clinical trials, one for the first-line treatment of advanced or metastatic HER2-positive gastroesophageal adenocarcinoma (HERIZON-GEA-01) and one for previously treated HER2-amplified biliary tract cancer (HERIZON-BTC-01). Zanidatamab is also being evaluated in several Phase 2 clinical trials for HER2 expressing gastroesophageal, colorectal, and breast cancers. The FDA has granted zanidatamab with Breakthrough Therapy designation for patients with previously treated HER2 gene-amplified biliary tract cancer, as well as two Fast Track designations, one as monotherapy for refractory biliary tract cancer and one in combination with standard of care chemotherapy for first-line gastroesophageal adenocarcinoma. These designations mean zanidatamab is eligible for Accelerated Approval, Priority Review and Rolling Review, as well as intensive FDA guidance on an efficient drug development program. Zanidatamab has also received Orphan Drug designations from the FDA as well as the European Medicines Agency for the treatment of biliary tract and gastric cancers.

About Evorpacept

Evorpacept is a next-generation CD47 blocking therapeutic that combines a high-affinity CD47 binding domain with an inactivated, proprietary Fc domain. Evorpacept is designed to avoid the limitations caused by hematologic toxicities inherent in other CD47 blocking approaches, and to leverage the immune activation of broadly used anti-cancer agents through combination strategies. ALX Oncology is developing evorpacept in multiple Phase 1 and Phase 2 clinical trials globally across a range of hematologic and solid malignancies in combination with a number of leading anti-cancer agents. The FDA has granted two Fast Track designations to evorpacept, one for the first-line treatment of patients with head and neck squamous cell carcinoma, and one for the second-line treatment of patients with HER2-positive gastric or gastroesophageal junction carcinoma. The FDA’s Fast Track designation provides the opportunity for more frequent meetings with the FDA over the course of drug development and allows for eligibility for Accelerated Approval and Priority Review if relevant criteria are met, as well as for Rolling Review.

"This is a defining moment in the fight against cancer and a powerful opportunity to reach more cancer patients with the leading treatments, care and advanced research they critically need," said Robert Stone, president and CEO of City of Hope and the Helen and Morgan Chu Chief Executive Officer Distinguished Chair. "CTCA has a strong commitment to patient-centric cancer care, and combining its network and services with City of Hope’s scientific expertise, clinical trials and patient care strengths will significantly increase the number of people who can access the latest lifesaving treatments."

City of Hope’s acquisition expands and accelerates the organization’s ability to rapidly translate research and science into lifesaving care through its unique model — connecting breakthrough discoveries and academic medicine expertise with excellent, community-based specialized cancer care to the benefit of patients and families served. This acquisition also expands the portfolio, reach and impact of City of Hope’s leading-edge cancer services and capabilities, including research and development, into more communities across the country.

"Building on more than three decades of unparalleled patient experience and quality care, we’re excited to become a part of City of Hope, and to take a step closer to reaching so many more cancer patients with our unique, patient-centered model," said Pat Basu, M.D., M.B.A., president and CEO of CTCA. "Through the shared, patient-centric values of both organizations and expanded access as a result of the collaboration, cancer patients across the nation will be the ultimate beneficiaries of this relationship."

City of Hope is a national leader in advancing cancer research and treatment protocols, conducting nearly 1,000 clinical trials annually that can enroll approximately 25% of its patients. With more than 450 patent portfolios, 95 active investigator-initiated investigational new drugs (INDs) and approximately 50 IND applications submitted to the U.S. Food & Drug Administration every year, City of Hope is among the leading innovators in cancer research. The organization is also a pioneer in bone marrow and stem cell transplants with one of the largest, most successful programs of its kind in the U.S., having performed more than 17,000 procedures.

With CTCA, City of Hope builds on and accelerates its vision to forge partnerships and find new avenues for its expertise to positively impact as many lives as possible. In addition to the ongoing, significant expansion of its clinical network in Southern California, City of Hope previously acquired Translational Genomics Research Institute (TGen), which provides breakthrough genomics research. TGen’s capabilities are fully leveraged to provide highly specialized care and precision medicine treatment to City of Hope patients across its clinical care network. And in 2019, City of Hope launched AccessHopeTM to extend the reach of its clinical and research expertise directly to partner employers, including 17 of the Fortune 500 companies, so they can provide their employees with cancer information and expert clinical decision support.

Combined, City of Hope and CTCA will include approximately 11,000 team members, comprising the collaborative expertise of 575 physicians across a network of locations in California, including a new campus in Irvine opening in summer 2022, as well as Arizona, Illinois and Georgia. Basu will remain CEO of CTCA and report to Robert Stone.

"Cancer treatment is changing rapidly. Today, through advances such as immunotherapy, precision medicine and other treatments available through clinical trials, there are better survival rates and fewer side effects than ever before. A critical part of cancer care is closing the gap to access that exists for too many patients, particularly in underserved communities," continued Stone. "By joining forces with CTCA, we’re taking a major step forward in our mission to democratize cancer care and bring today’s treatments and tomorrow’s discoveries to even more people who need them now."

The transaction is expected to close in early 2022, subject to regulatory approvals. After close, City of Hope intends to convert CTCA to a nonprofit organization.

Non-GAAP Financial Measure

This press release includes a forecast of Adjusted Earnings per Diluted Share, which is not a financial measure calculated in accordance with U.S. generally accepted accounting principles (GAAP). The company is unable to provide a quantitative reconciliation of this forward-looking Non-GAAP measure to the equivalent forward-looking GAAP measure without unreasonable effort, because the company does not forecast GAAP earnings per share and cannot reliably forecast LIFO inventory-related adjustments, certain litigation loss and gain contingencies, restructuring, impairment and related charges, and other adjustments, which are difficult to predict and estimate. These items are inherently uncertain and depend on various factors, many of which are beyond the company’s control, and as such, any associated estimate and its impact on GAAP performance could vary materially. Refer to investor.mckesson.com and the company’s slide presentation noted above for definitions and explanations of the Company’s Non-GAAP financial measures.

About H3B-6545

Estrogen receptor alpha (ERα) plays an important oncogenic role in the genesis and progression of luminal breast cancers,1 and historically has been a target of endocrine therapies. However, recently, hotspot mutations in ERα have been detected in nearly 30% of endocrine-therapy resistant metastases. Functional studies have shown that these ERα mutations can confer ligand-independent activation of the ERα pathway and can promote partial resistance to existing classes of ER-directed therapies.2,3 H3B- 6545, a first-in-class small molecule selective estrogen receptor covalent antagonist (SERCA) demonstrates activity in tumor models that harbor wild-type or mutant ERα.4 H3B-6545 activity against ERα mutants resistant to standard therapy provides an opportunity to target a currently unmet medical need both as a single agent and in combination with other breast cancer therapies.
