Iruplinalkib, a next-generation ALK/ROS1 kinase inhibitor formulated by Qilu Pharmaceutical, was approved by NMPA in June 2023 for the treatment of patients with ALK-positive locally advanced or metastatic NSCLC who had disease progression after treatment with crizotinib or who were intolerable to crizotinib. In January of this year, iruplinalkib was approved for the first-line treatment of patients with ALK-positive NSCLC.

The trial is led by principal investigator, Prof. Yuankai Shi from the Cancer Hospital Chinese Academy of Medical Sciences & Peking Union Medical College. The results of the study were published in BMC Medicine in 2023. Updated data with an extended two-year follow-up were presented during the WCLC.

A total of 146 subjects were enrolled in this study. As of December 29, 2023, the median follow-up time was 42.41 months, revealing a median overall survival (OS) of 41.79 months. The investigator-evaluated objective response rate (ORR) was 63.7%, while the disease control rate (DCR) reached 94.5%. Additionally, the median duration of response (DoR) and median progression-free survival (PFS) were reported to be 14.06 months and 14.55 months, respectively.

According to the RECIST v1.1 evaluation criteria, the ORR and DCR in the subgroup with CNS metastasis at baseline (90 patients) were 55.6% and 93.3%, respectively. Both the median DoR and median PFS were 17.25 months, while the median OS stood at 43.01 months.

Based on RANO-BM criteria, intracranial complete response (CR) was achieved in 17 (18.9%) of the 90 patients with CNS metastasis at baseline. Among the 42 subjects with measurable intracranial lesions at baseline, the intracranial objective response rate (iORR) was 64.3% while the intracranial disease control rate (iDCR) reached 95.2%.

The safety profile was characterized by a 93.8% (137 cases) incidence of treatment-related adverse events (TRAEs), with 30.8% (45 cases) being grade 3 or 4. The most common TRAEs included elevated aspartate aminotransferase (45.2%), hypercholesterolemia (37.7%), and increased alanine aminotransferase (37.0%). No new safety signals were identified.

Long-term follow-up results from the INTELLECT study demonstrated that iruplinalkib provided an OS benefit with no new safety signal in patients with ALK-positive crizotinib-resistant advanced NSCLC.

On September 10, 2024 I-Mab (NASDAQ: IMAB) (the "Company"), a U.S.-based, global biotech company exclusively focused on the development of highly differentiated immunotherapies for the treatment of cancer, reported a poster presentation of PK/PD modeling data for uliledlimab at the International Association for the Study of Lung Disease (IASLD)’s 2024 World Conference on Lung Cancer (WCLC 2024) held September 7-10, 2024 in San Diego, CA (Press release, I-Mab Biopharma, SEP 10, 2024, View Source [SID1234646482]).

Uliledlimab (TJ004309) is an antibody designed to target CD73, the rate-limiting enzyme critical for adenosine-driven immunosuppression in the tumor microenvironment. Blocking CD73 allows anti-tumor immunity to proceed without the presence of an adenosine-induced "immunological fog". The WCLC 2024 presentation includes data from uliledlimab PK/PD analyses from three Phase 1 studies including patients with treatment naïve metastatic non-small cell lung cancer (mNSCLC).

"The PK/PD analysis presented at WCLC underscores our view that uliledlimab has the potential to be a differentiated, best-in-class, CD73 inhibitor. The data support our dose selection work and upcoming combination studies, with a study of uliledlimab plus pembrolizumab plus chemotherapy expected to begin in the first half of 2025," said Phillip Dennis, MD, PhD, Chief Medical Officer of I-Mab. "We are particularly encouraged by the E-R analysis, which showed a positive relationship between uliledlimab exposure and the probability of an overall response in patients with NSCLC, as well as positive target engagement data and dose proportional PK results. These data, plus a previously presented favorable safety profile and clinical efficacy, fortify our view that uliledlimab has the potential to meaningfully improve the care of patients with mNSCLC."

Poster Title: Integrated PK/PD Modeling for Uliledlimab, an Anti-CD73 Monoclonal
Antibody, in Non-Small Cell Lung Cancer Patients (Poster #2979)

Data are based on analysis of three Phase 1 studies conducted in China evaluating uliledlimab, as a monotherapy and in combination studies with the checkpoint inhibitors, toripalimab or atezolizumab, in patients with advanced cancers, including mNSCLC.

Key Findings Include:

Most of the simulated population (95%) could achieve the target threshold with 30 mg/kg of uliledlimab
Integrated PK/PD modeling and pharmacometrics analyses indicate there is a positive relationship between the probability of overall response and uliledlimab trough concentration in NSCLC patients
CD73 receptor occupancy (RO) in peripheral B cells achieved 90% or above and maintained at high levels until the end of treatment
The 30 mg/kg dose with a single boost dose on C1D8 provided uliledlimab concentrations that achieved the target concentration of 80 μg/mL immediately after the first dose and maintained this threshold afterward
A Ctrough target threshold of 80 μg/mL may be clinically meaningful, associated with PFS benefit and is achievable by a 30 mg/kg initial dose followed by a booster dose on Cycle 1, Day 8 (C1D8)
A full copy of the poster is available on the I-Mab website, on the "Innovation, Publications & Presentations" tab.

On September 10, 2024 OncoHost, a technology company transforming the approach to precision medicine for improved patient outcomes, reported its selection to present a poster at the European Society of Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress 2024, which will take place from September 13 to 17, 2024, in Barcelona, Spain (Press release, OncoHost, SEP 10, 2024, View Source [SID1234646481]).

The abstract, titled "A plasma proteomic based algorithm is associated with prognosis in renal cell carcinoma," highlights the extended application of OncoHost’s PROphet platform beyond non-small cell lung cancer (NSCLC) to renal cell carcinoma (RCC). This research represents a collaboration between OncoHost and Dana-Farber Cancer Institute, a world leader in adult and pediatric cancer treatment and research. The findings will be presented by Dr. Eddy Saad, MD, MSc, a Postdoctoral Research Fellow at Dana-Farber.

"In this work, we demonstrated that OncoHost’s plasma-based proteomic model, initially trained and validated in NSCLC, can also be applied to another tumor type, RCC, to risk stratify patients," said Dr. Eddy Saad, MD, MSc, Postdoctoral Research Fellow at Dana-Farber, and co-author of the abstract. "Moving forward, we aim to further develop and train an RCC-specific model and assess its predictive abilities to guide patient treatment."

The study explored the use of OncoHost’s PROphet platform in a cohort of 201 RCC patients treated with various therapies, including VEGFR tyrosine kinase inhibitors (TKIs), immune checkpoint inhibitors (ICIs), or a combination of both. The results demonstrated that patients identified as PROphet-POSITIVE had significantly improved overall survival (OS) and progression-free survival (PFS) compared to PROphet-NEGATIVE patients, indicating the platform’s potential to predict clinical outcomes across various cancer types.

Furthermore, the research uncovered distinct subsets of circulating proteins associated with clinical benefit among patients treated with different therapies, suggesting that the proteomic features leveraged by the PROphet platform may have broad predictive value. These findings provide a strong foundation for further exploration of PROphet’s application in other cancer indications and treatment contexts.

"This research marks another important milestone for OncoHost, as it demonstrates the versatility and potential of our PROphet platform across different cancer types. By validating the use of our proteomic model in renal cell carcinoma, we are moving closer to our goal of providing personalized treatment plans that significantly improve patient outcomes," said Ofer Sharon, MD, CEO of OncoHost. "We are honored to partner with Dana-Farber in presenting these findings at ESMO (Free ESMO Whitepaper) 2024 and look forward to further expanding the clinical applications of our technology."
