Accounting Metric: Discussion, by world region, of management process for ensuring quality and patient safety during clinical trials

BioMarin 2023/24 Disclosure: BioMarin is committed to the safety of the patients and healthy volunteers who take part in our clinical trials, maintaining the highest ethical, scientific and clinical standards in all of our research initiatives worldwide. To ensure appropriate protection and respect for the rights of study participants, all BioMarin-sponsored clinical trials are designed and conducted to meet or exceed all applicable local laws and regulations and globally recognized principles of international ethics, such as the International Conference on Harmonization (ICH) E6 Good Clinical Practice (GCP) Guidelines. BioMarin maintains detailed internal procedures to ensure rigorous compliance with these laws and regulations and cultural alignment with the countries in which studies are conducted. The procedures include active safety surveillance and high quality, science-based proactive risk management by our Global Pharmacovigilance team. Every potential new BioMarin therapy undergoes preclinical and clinical testing and review to establish its safety and efficacy profile, with each clinical trial reviewed and approved prior to its start by a specific Independent Review Board (IRB) or Ethics Committee (EC) including medical, scientific and non-scientific members. Following product marketing approval from health authorities, safety data collection reporting continues through multiple channels, including additional clinical and post-marketing studies, patient and healthcare professional (HCP) reports, registries and scientific literature.

Accounting Metric: Description of actions and initiatives to promote access to health care products for priority diseases and in priority countries as defined by the Access to Medicine Index

BioMarin 2023/24 Disclosure: Access to Our Therapies in Low- and Middle-Income Regions

At BioMarin, it’s not enough to make transformative medicines: we work to ensure that people from low- and middle-income regions have access to our therapies. Treatment for rare conditions comes with unique challenges, and the path to access varies in each region. For these reasons, we partner with all those involved in breaking down regional obstacles and facilitating paths to care, including doctors, health officials, researchers, community advocates, suppliers and patients themselves.

Our approach includes:

• Reaching national pricing agreements with a number of low- and middle-income countries.
• Adjusting established agreements following major regional events such as armed conflict and natural disasters
• Tailoring drug delivery processes to meet unique regional needs: for example, identifying ways to maintain frozen medicines in route to areas with infrastructure challenges
• Partnering in initiatives to improve diagnostic capacity and identify those in need of treatment
• Designing patient support programs that address specific barriers to care in individual regions

Accounting Metric: Total amount of product accepted for takeback, reuse, or disposal

BioMarin 2023/24 Disclosure: BioMarin is a member of the Pharmaceutical Product Stewardship Work Group (PPSWG), which:

• coordinates pharmaceutical industry members’ efforts to respond to household pharmaceutical products and sharps take-back laws,
• provides legislative and regulatory updates to its members on developing and existing laws, and
• provides strategic guidance for stewardship programs.

MED-Project USA serves as the stewardship organization designated by PPSWG members to implement and operate mandated take-back programs. As part of this effort, MED-Project USA provides and publicizes locations to dispose of unwanted, unused or expired household medicines. BioMarin does not receive data from PPSWG tracking the amount of product accepted for takeback, reuse or disposal. However, BioMarin manufactures and sells specialty products for rare diseases, many of which are administered in clinic. Thus, while BioMarin engages with PPSWG to maintain awareness of, and compliance with, relevant laws, BioMarin would not expect any significant volume of unwanted, unused or expired product to be found in US households.

Our practices include aggregating serialized information to enable track-and-trace and utilizing relevant national alert systems, such as the National Medicines Verification Organisation (NMVO).

In addition to these internal processes, BioMarin participates in industry-wide partnerships with other pharmaceutical companies and organizations focused on protecting public health, sharing information on falsified medicines (and approaches to counter illicit trade), and engages with local and national-level authorities when enforcement actions are appropriate.
