Clinical Performance Study SP2024001, is a prospective, interventional study to assess the clinical performance of the APOL1 Genotyping Clinical Trial Assay (CTA) in the intended use population and environment. The study will use the APOL1 Genotyping CTA to test deoxyribonucleic acid (DNA) extracted from blood specimens to identify individuals who are homozygous or compound heterozygous for apolipoprotein L1 (APOL1) high-risk genotypes (G1 and G2).The individuals who are identified as being homozygous or compound heterozygous for the APOL1 high-risk genotypes are candidates for enrolment onto an pharmaceutical company-sponsored, Phase 2b clinical trial which is investigating the safety and efficacy of a synthetic antisense oligonucleotide (ASO) for the treatment of APOL1-mediated kidney disease (AMKD).

Inclusion Criteria:

• Study participants must be identified as a potential candidate for the pharmaceutical company- sponsored clinical trial by their physician based on the clinical trial inclusion criteria.
• Study participant has agreed to and signed the clinical trial Informed Consent Form (inclusive of risks related to the APOL1 Genotyping CTA).
• The study participant's specimen must be distributed to the device test site accompanied by a complete Test Request Form signed by the appropriate clinical trial site personnel.
• All participant specimens must meet predetermined specifications (e.g., undamaged, appropriate volume, appropriate specimen type, appropriate disease indication) for acceptance for testing by the device test site in accordance with established procedures.

Exclusion Criteria:

• Study participants will be excluded as a potential candidate for the pharmaceutical company -sponsored clinical trial by their physician based on the clinical trial exclusion criteria as assessed at screening visit 1.
• The study participant has not agreed to and signed the (Clinical Trial) Informed Consent Form.
• The study participant's specimen is distributed to the device test site without a complete Test Request Form.
• The study participant's specimen did not meet predetermined specifications for acceptance for testing by the device test site in accordance with established procedures.

All IPD, inclusive of the APOL1 Genotyping Clinical Trial Assay result

Start date March 2025 End date March 2027

The results of the APOL1 Genotyping CTA will be returned to the requesting clinical site (inclusive of clinical trial investigator) and the pharmaceutical clinical trial sponsor. The clinical trial investigator may return the result, if requested by the participant with appropriate genetic counselling. The device study will utilize remote electronic data capture systems to store and transfer data. Transfer of device data from Almac Diagnostic Services to the pharmaceutical clinical trial sponsor or other 3rd parties will be governed by agreed data transfer agreements and in line with local regulations.

Almac Diagnostic Services receives de-identified specimens only for inclusion in the clinical performance study. The clinical trial protocol describes the blinding and un-blinding procedures for the clinical trial and this responsibility lies with the pharmaceutical clinical trial sponsor.
