Summary of the Conference Call for ReLi Pharma Company Overview - **Company**: ReLi Pharma - **Focus**: Oncology and Immunology Key Points and Arguments 1. Clinical Data on Soli - In the FURTHER study, Soli demonstrated good safety with only 13% of patients experiencing grade 3 or higher adverse events, significantly lower than other studies reporting 35% to 50% [2][9] - The overall response rate was 60%, with a response rate of 80% in patients with brain metastases who had not received prior radiotherapy [2][9] - The median duration of response was 6.1 months, indicating potential as a treatment for relapsed small cell lung cancer (SCLC) [2][3][9] 2. Development Plans for Soli - ReLi Pharma plans to initiate a registration trial for Soli targeting investigator-selected treatment regimens, with interim data expected in early 2027 [2][10] - The company is also advancing the 19th flight study to explore earlier treatment lines, including combinations with anti-PD-L1 and chemotherapy [2][10] 3. Pipeline Progress - The global innovation pipeline includes Soli for second-line lung cancer treatment and a new generation therapeutic antibody L15O3 for atopic dermatitis, expected to complete Phase I trials by 2026 [4][5] - Other oncology compounds like DL62, O1, RLRC15, and ADC are anticipated to enter clinical trials in 2026 [5] 4. Challenges in Small Cell Lung Cancer - SCLC accounts for about 15% of all lung cancer cases, with over 370,000 new cases globally each year [6] - Approximately 2/3 of patients are diagnosed at an advanced stage, with a median survival time of about 1 year and a high incidence of brain metastases [6] 5. Ideal Target for SCLC - Triangular ligand 3 is expressed in over 85% of SCLC cases and is considered an ideal target due to its low expression in healthy tissues [7][8] 6. Future Regulatory Strategy - ReLi Pharma expects to submit an accelerated approval application for Soli in 2027, with potential approval by late 2027 or early 2028 [11][17] 7. Importance of Efficacy Duration - In single-arm trials, duration of efficacy is deemed more important than progression-free survival (PFS) as it reflects the time patients benefit from the drug [13] 8. Competitive Landscape - ReLi Pharma's registration strategy positions it 1.5 to 2 years ahead of competitors, which is crucial for maintaining a competitive advantage in the market [17] 9. Brain Metastases Treatment - The ability of Soli to penetrate the blood-brain barrier and effectively treat brain metastases is highlighted as a significant advantage, especially for patients with limited treatment options [18] 10. Future Research Directions - ReLi Pharma is exploring combinations with other therapies, including immunotherapy, to enhance treatment efficacy for SCLC and neuroendocrine cancers [19][20] Additional Important Information - The company emphasizes the need for new therapies to improve outcomes in SCLC due to the severe side effects of existing treatments and the urgent demand for effective solutions [6][10]
