"We are very excited about the APVO436 data, demonstrating that our lead drug is generally well tolerated and showing preliminary signs of efficacy in the treatment of patients with relapsed or refractory AML and MDS who are in urgent need for new therapeutic options," said Marvin White, CEO of Aptevo. "Our work on APVO436 is on-going and we look forward to sharing new outcomes, as they become available."

About APVO436

Overexpression of CD123 is the hallmark of many forms of leukemia. Aptevo’s lead proprietary drug candidate, APVO436 is a bispecific CD3xCD123 ADAPTIR that is designed to redirect the immune system of the patient to destroy leukemia cells expressing the target CD123 molecule on their surface. This antibody-like recombinant protein therapeutic is designed to engage both leukemia cells and T-cells of the immune system and bring them closely together to trigger the destruction of leukemia cells. APVO436 has been engineered using Aptevo’s proprietary and enabling bioengineering methods and is designed to reduce the likelihood and severity of CRS. APVO436 has received orphan drug designation ("orphan status") for AML according to the Orphan Drug Act.

DiaCarta’s ColoScape™ Assay Detects Precancerous Colorectal Cancer Lesions and Colorectal Cancer Mutations with High Sensitivity

On October 27, 2021 DiaCarta Inc., a precision molecular diagnostics company and leading developer of novel oncology tests using liquid biopsy, reported the publication of a study in PLOS ONE that demonstrates that DiaCarta’s ColoScape Xenonucleic Acid (XNA)-mediated quantitative real-time polymerase chain reactions (qPCR) clamping assay detects mutant cell-free DNA (cfDNA) from precancerous colorectal cancer (CRC) lesions and colorectal cancer (Press release, DiaCarta, OCT 27, 2021, View Source [SID1234592074]).

The paper entitled, "A novel xenonucleic acid-mediated molecular clamping technology for early colorectal cancer screening," evaluated the performance of XNA-mediated qPCR clamping technology for the simultaneous and qualitative detection of somatic mutations in CRC patients.1 Nineteen mutations in a panel of genes associated with early events in CRC pathogenesis are targeted in the ColoScape assay.

The ColoScape XNA-mediated qPCR clamping assay is a novel multi-gene mutation diagnostic assay for the qualitative detection of colorectal cancer-associated gene mutations in liquid biopsy and FFPE tissue samples. ColoScape utilizes XNA technology, innovative synthetic Xenonucleic acid molecular oligomers that hybridize with target wild-type DNA sequences. The XNA oligomers act as molecular clamps to enable the accurate amplification of mutant sequences only, using qPCR.

In this study, a total of 380 clinical samples, including plasma cfDNA and FFPE samples from patients with precancerous and different stages of CRC, were analyzed with the ColoScape assay.1 With liquid biopsy the preliminary assay clinical specificity for CRC was 100% and the clinical sensitivity was 92.2%; for precancerous lesions clinical specificity was 95% and clinical sensitivity was 62.5%.1 With FFPE samples the preliminary assay clinical specificity for CRC was 96% and the clinical sensitivity was 92%, making this assay robust, specific and highly sensitive. Currently, DiaCarta has large clinical trials ongoing in Europe, Asia, and US.

"This study validates the diagnostic application of the ColoScape assay in the early detection of precancerous lesions and colorectal cancer based on the amplification and detection of cfDNA mutants from one tube of blood," said Aiguo (Adam) Zhang, Ph.D., CEO, DiaCarta, Inc. "Our technology has the potential to disrupt the standard method of FFPE or stool samples used for the diagnosis of colorectal cancer. ColoScape’s sensitivity and specificity may yield detection of colorectal cancer before the disease progresses to more acute stages. In addition, our new generation of ColoScape test includes a panel of methylation genes powered by XNA, which generates even higher sensitivity, especially for the precancerous lesions."

"As we begin the last quarter of 2021, we are very pleased to be improving both top and bottom-line financial guidance for the full-year," said Jean-Jacques Bienaimé, Chairman and Chief Executive Officer of BioMarin. "Uneven ordering patterns are a consistent element of our dynamic global commercial business, making full-year results the key indicator of product demand. The essential nature of our medicines to the people who rely on them, gives us confidence in the growth prospects ahead. We plan to finish 2021 strong and expect meaningful growth in revenues in 2022 leading to anticipated GAAP profitability next year. We look forward to providing full guidance for 2022 early next year, especially given early demand signals for Voxzogo, for the treatment of achondroplasia, in Europe, and the potential for Voxzogo to be approved in the U.S. next month."

Mr. Bienaimé continued, "Foundational milestones are tracking to plan, starting with the European approval and launch of Voxzogo in the quarter. The level of interest in Voxzogo following approval has exceeded our expectations. If Voxzogo is approved in the U.S. next month, we expect the global Voxzogo launch to contribute meaningfully to our commercial business. Our next significant read-out, the two-year data from the 134-participant Phase 3 study with valoctocogene roxaparvovec gene therapy for the treatment of severe hemophilia A, will be shared in early 2022. We anticipate resubmitting the U.S. application in the second quarter of 2022, and we continue to anticipate the European opinion in the second quarter of 2022, should data be supportive. The cascade of these potential new product approvals, including global approvals of valoctocogene roxaparvovec and U.S. approval of Voxzogo, sets us up for significant potential growth beginning in 2022."

Financial Highlights:

Total Revenues for the third quarter of 2021 decreased to $408.7 million, compared to $476.8 million for the same period in 2020. The decrease in Total Revenues was primarily attributed to the following:
Lower Kuvan product revenues primarily due to generic competition due to the loss of exclusivity in the U.S., which was consistent with expectations.
Lower Aldurazyme product revenues due to timing of product fulfillment to Genzyme. BioMarin Aldurazyme revenues are driven by the timing of when the product is released and control is transferred to Genzyme to be marketed. Revenues for the third quarter of 2021 were comparatively lower than 2020 due to such timing. Based on data provided to us by Genzyme, patients receiving commercial Aldurazyme increased by approximately 10%, year-over-year. Aldurazyme 2021 revenues are expected to grow in the fourth quarter of 2021 compared to the fourth quarter of 2020.
Lower Vimizim and Naglazyme product revenues primarily driven by timing of orders from Europe and the Middle East. High patient compliance rates during the quarter and year-over-year patient growth of approximately 10% for both Naglazyme and Vimizim reflected strong underlying demand.

These factors were partially offset by the following:

Higher Palynziq product revenues primarily due to a combination of revenues from more patients in the U.S. achieving maintenance dosing and new patients initiating therapy, which increased approximately 20% year-over-year. We expect the number of U.S. Palynziq patients to grow as U.S. PKU clinics re-open over the coming months. The commercial launch of Palynziq in BioMarin’s European, Middle East and African (EMEA) region continues to progress through individual country level pricing and reimbursement negotiations.
Higher Brineura product revenues due to new patients initiating therapy driven by growth in EMEA and North America. Strong patient compliance during the quarter and year-over-year patient growth of approximately 20% reflected strong underlying demand.
Total Net Product Revenues Marketed by BioMarin, excluding Kuvan, increased in the third quarter 2021 compared to the third quarter 2020.
GAAP Net Loss increased to $36.5 million for the third quarter of 2021 compared to GAAP Net Income of $784.8 million for the same period in 2020. GAAP Net Income in the third quarter of 2020 was primarily related to the $835.1 million benefit from income taxes related to the intra-entity transfer of certain intellectual property rights to an Irish subsidiary, and there was no similar transaction in the third quarter of 2021.
Non-GAAP Net Income for the third quarter of 2021 decreased to $33.5 million compared to Non-GAAP Income of $98.7 million for the same period in 2020. The decrease in Non-GAAP Income for the quarter, compared to the same period in 2020, was primarily attributable to lower net product revenues.
Late-stage Regulatory Portfolio (Voxzogo and valoctocogene roxaparvovec)

During the quarter, the European Commission approved Voxzogo for the treatment of children, ages 2 years and older. The commercial launch of Voxzogo is underway, with revenues for the remainder of 2021 expected from France, Germany and select early-access countries. Marketing authorization reviews are in process in Japan, Brazil and Australia, with potential approvals in those countries in 2022.
The FDA is reviewing the Voxzogo New Drug Application (NDA) with the PDUFA target action date of November 20, 2021.
The European Medicines Agency (EMA) validated BioMarin’s MAA for valoctocogene roxaparvovec resulting in an anticipated CHMP opinion in the first half of 2022, assuming favorable results from the two-year follow-up safety and efficacy data from the GENEr8-1 study.
BioMarin is targeting a BLA resubmission for valoctocogene roxaparvovec in the second quarter of 2022, also assuming favorable results from the two-year follow-up safety and efficacy data from the GENEr8-1 study, followed by an expected 6-month review procedure by the FDA.
Earlier-stage Development Portfolio (BMN 307, BMN 255, BMN 331, BMN 351, DiNA-001, Allen Institute Collaboration, Deep Genomics)

Details for BioMarin’s virtual R&D Day on November 30, 2021 will be made available over the coming weeks. The Company plans to share an in-depth review of multiple early-stage pipeline programs showcasing next potential IND candidates.
BMN 307 gene therapy product candidate for PKU: The FDA placed a clinical hold on PHEarless, the Phase 1/2 study evaluating BMN 307, an investigational AAV5-phenylalanine hydroxylase (PAH) gene therapy, in adults with phenylketonuria (PKU). The hold was based on pre-clinical study findings from a model designed to understand the durability of BMN 307 activity in mice bearing two germline mutations, one rendering the mice immunodeficient. The clinical significance of these findings is being evaluated to assure safe and appropriate use of BMN 307. To date, findings appear specific to mice and have no known translatability to humans or other gene therapy vectors. BioMarin is working with health authorities to address the clinical hold and resume study investigations, as appropriate.
BMN 255 for a subset of chronic renal disease: The Investigational New Drug application (IND) for BMN 255 is active and the Company is dosing subjects. Kidney damage can progress to end stage renal disease, and the availability of a potent, orally bioavailable, small molecule like BMN 255, may be able to significantly reduce disease and treatment burden in certain people with chronic renal disease.
BMN 331 gene therapy product candidate for Hereditary Angioedema (HAE): BioMarin is leveraging its broad expertise in gene therapy to improve efficiencies in the development process of BMN 331. The IND for BMN 331 has been allowed by FDA and the first patient is expected to be enrolled around the end of 2021. Patients with HAE may experience benefit from the constitutive expression and stable C1-INH protein levels potentially provided by gene therapy, thus reducing the frequency and severity of attacks and reducing the burden associated with current standard of care.
BMN 351 for Duchenne Muscular Dystrophy (DMD): IND-enabling studies continue with BMN 351, an antisense oligonucleotide therapy for individuals with 51-skip-amenable DMD. BMN 351 was developed using familiar chemistry and superior biology, by targeting a novel, upstream, splice enhancer site demonstrating improved binding affinity and metabolic stability in preclinical models. Preclinical data suggest that restored expression of near-full-length dystrophin protein at previously achieved levels of up to 40% will convert phenotypes from rapid loss to durable preservation of strength and ambulation. BioMarin anticipates filing an IND for BMN 351 in the first half of 2022.
DiNA-001 for MYBPC3 hypertrophic cardiomyopathy (HCM): Pre-clinical studies are underway with DiNA-001 following a collaboration announced in 2020 with DiNAQOR, a gene therapy platform company, to develop novel gene therapies to treat rare genetic cardiomyopathies. Mutations in MYBPC3 are the most common cause of inherited HCM. Early investigations suggest that gene therapy-mediated gene transfer can lead to widespread expression of the gene product, cardiac myosin-binding protein C (MyBP-C), in cardiac tissue, which can normalize relaxation kinetics and potentially ameliorate the disease phenotype in individuals suffering from cardiomyopathy.
BioMarin and the Allen Institute are collaborating to create new gene therapies aimed at rare genetic diseases of the central nervous system (CNS). The goal is to combine the Allen Institute’s leadership in large-scale genomic science in the CNS therapeutic area with BioMarin’s expertise in developing transformational therapies for complex conditions, such as Brineura for CLN2. The phenotypes associated with some of these conditions have the potential to demonstrate profound recoverability and transformational outcomes, particularly when treated early. This partnership expands and fortifies BioMarin’s capabilities and expertise in the CNS therapeutic area.
Deep Genomics and BioMarin recently entered into a collaborative agreement to develop oligonucleotide drug candidates in four rare disease indications. Through this collaboration, BioMarin will advance lead compounds identified and validated using Deep Genomics’ artificial intelligence (AI) drug discovery platform into preclinical and clinical development. As part of this collaboration, BioMarin receives an exclusive option to each of the four disease programs for development and commercialization. By using a combination of Deep Genomics’ advanced analytics and BioMarin’s expertise in rare disease drug development, the collaboration could efficiently unlock a path to identify molecular disease targets for novel therapeutics.
