NalaGenetics, a pioneering spin-off from the Agency for Science, Technology and Research’s (A*STAR) Genome Institute of Singapore, is poised to revolutionize the treatment landscape of leprosy in Indonesia through an innovative nationwide genetic screening program using their proprietary PGx1301 diagnostic kit. This ambitious initiative, slated to begin in the fourth quarter of 2025, is rooted in compelling insights gained from a successful five-year pilot study in East Indonesia, which underscored the transformative power of precision medicine. The pilot, which was meticulously designed, demonstrated how targeted genetic testing is instrumental in preventing severe and potentially life-threatening adverse drug reactions, known as ADRs, in leprosy patients who are prescribed dapsone, an essential antibiotic.
At the heart of this groundbreaking program is the screening of up to 16,000 leprosy patients every year for the HLA-B*13:01 biomarker, a genetic variant that has been critically associated with Dapsone Hypersensitivity Syndrome (DHS). This severe reaction to dapsone can lead to significant mortality rates if unrecognized and untreated. The scale and scope of this initiative represent a monumental step forward in the global mission to eliminate leprosy, a disease that continues to disproportionately affect vulnerable populations in tropical regions where access to adequate healthcare remains a challenge. By integrating genetic screening into the treatment protocol for leprosy, NalaGenetics is setting a new standard for patient safety and treatment efficacy.
Leprosy, otherwise known as Hansen’s disease, represents a persistent global health challenge, with a prevalence rate that remains alarmingly high. Recent statistics indicate that there are approximately 16.9 cases of leprosy per million individuals globally, underscoring the urgency of interventions that can mitigate its spread and impact. The underlying causative agents of leprosy, Mycobacterium leprae and Mycobacterium lepromatosis, can result in irreversible nerve damage and debilitating physical disabilities if left untreated. Recognizing this, the planned nationwide rollout of genetic screening in Indonesia signifies a major evolution in the nation’s healthcare strategy concerning infectious diseases.
Since the commencement of genetic testing in regional laboratories across Papua in 2021, NalaGenetics has reported remarkable outcomes—nearly zero cases of DHS—among the new leprosy patients being screened. This astonishing success demonstrates the life-saving potential of precision medicine, especially in regions where healthcare resources may be limited. The historical data revealing a corresponding 9.9% mortality risk associated with DHS highlights the critical importance of early detection and preventive strategies, which are now becoming available on a national level in Indonesia.
NalaGenetics’ journey commenced in 2016 when its visionary founders, Dr. Astrid Irwanto, Dr. Levana Sani, Prof. Liu Jianjun, and Dr. Alexander Lezhava, identified a pressing gap in healthcare: an urgent need for accessible and affordable genetic testing aimed at preventing ADRs in patients with diverse health conditions. Supported by A*STAR GIS, the company harnessed rapid, real-time PCR technology, allowing them to develop a breakthrough diagnostic kit that is both affordable and highly accurate.
The strategic partnership formed in 2018 with the Health Research Institute of the Indonesian Ministry of Health marked a critical turning point for NalaGenetics. This collaboration led to the establishment of the first government-supported clinical trial for genetic screening in leprosy patients, covering three provinces and five districts. The outcome was both revealing and encouraging: the trial outcomes revealed that 20% of the leprosy patients screened were found to carry the HLA-B*13:01 biomarker, and notably, there were no reported cases of DHS, reinforcing the invaluable life-saving capabilities of incorporating genetic testing into routine clinical practice.
Dr. Levana Sani, the Chief Executive Officer of NalaGenetics, articulated the significance of this initiative: "This undertaking encapsulates Singapore’s growing prominence in the international precision medicine arena. By merging cutting-edge scientific advancements with a profound understanding of regional healthcare challenges, we’ve crafted a solution that not only saves lives but also establishes a benchmark for the scalability of genetic testing in resource-constrained environments."
The reach of NalaGenetics extends beyond Indonesia; with support from international partners including the Netherlands Leprosy Relief, the firm has progressively initiated clinical trials in Nepal and India. These efforts have successfully affirmed the universal applicability of the HLA-B*13:01 biomarker within Asian populations, accentuating the global impact of the scientific developments championed by NalaGenetics. The culmination of their efforts has been recognized through peer-reviewed publications in esteemed journals, including PLOS Neglected Tropical Diseases, further solidifying the scientific integrity underpinning their life-saving interventions.
Dr. Wan Yue, Executive Director of A*STAR GIS, emphasized the profound societal impact of NalaGenetics’ journey, stating that their work exemplifies how rigorous scientific research can positively influence global health outcomes. Their initiatives not only benefit the residents of Singapore but also aim to extend health improvements to underserved populations worldwide. This is a prime illustration of how applied scientific research can bridge the healthcare gap that often exists in tropical and resource-limited settings.
Moreover, the co-founder of NalaGenetics and Distinguished Principal Scientist at ASTAR GIS, Prof. Liu Jianjun, expressed his enthusiasm regarding the decision of the Indonesian government to adopt the HLA-B13:01 screening test on a nationwide scale. Notably, while leprosy may not be as prevalent in Singapore, the implications of this research are vast, influencing multiple health challenges that affect the region. The pioneering work being conducted by NalaGenetics signifies a concerted effort to harness the power of genomics to improve health outcomes not just for Singaporeans, but for millions of people across Asia.
As NalaGenetics continues to explore the potential applications of their genetic testing platform, ambitious plans are in place to extend their technology to other health conditions including cardiovascular diseases and diabetes. Dr. Sani articulates the overarching vision of making precision medicine universally accessible, dedicating efforts to empower healthcare providers with advanced tools required to deliver personalized and effective patient care. By leveraging their profound expertise in genomics and data analytics, NalaGenetics aims to enable healthcare systems to transition towards a framework that prioritizes personalized medicine.
The initiative by NalaGenetics serves as a beacon of innovation in the field of global healthcare, demonstrating the pivotal role that genetic insights will play in combating long-standing health challenges. As precision medicine continues to gain momentum across various health arena, NalaGenetics stands at the forefront, positioning Singapore as a key player in the global healthcare landscape.
