Discovered by Kangpu Biopharmaceuticals, KPG-121 is a modulator of the Cereblon (CRBN) E3 ubiquitin ligase complex CRL4CRBN targeting rapid ubiquitination and degradation of casein kinase 1α (CK1α) and transcription factors Aiolos (IKZF3) and Ikaros (IKZF1). KPG-121 promotes anti-proliferation and anti-angiogenesis activities and enhances immunomodulatory properties. KPG-121 significantly improves anti-tumor efficacies when combined with androgen-receptor antagonists including enzalutamide, abiraterone acetate, apalutamide, or darolutamide in xenograft models when compared to the androgen-receptor antagonist therapy alone. A Phase I study to evaluate the safety, pharmacokinetics, and efficacy of KPG-121 when combined with enzalutamide, abiraterone, or apalutamide for the treatment of patients with metastatic or non-metastatic castration-resistant prostate cancer was completed in the US (NCT03569280). KPG-121 was generally well tolerated and demonstrated a favorable pharmacokinetic profile as well as promising efficacy.

The poster presentation highlighted the potential implementation of its liquid biopsy platform using multimodal deep learning technology to detect colorectal cancer in clinical data. The study incorporates 1,506 colonoscopy-verified normal samples, 130 AA patients, and 302 CRC patients (with a breakdown of stages). This innovative approach demonstrated high sensitivity for CRC detection across all stages, including early-stage lesions, while maintaining high specificity.

"The development of non-invasive screening methods for colorectal cancer is crucial for improving early detection and patient outcomes," said Eun-Hae Cho M.D., Ph.D., Chief Scientific Officer at GC Genome. "By emphasizing the necessity for a non-invasive approach, this research brings us nearer to the development of a convenient, accessible screening option for patients. It has the potential to bridge the current screening gap and surpass the limitations of traditional methods. And we are excited to continue our work to bring this technology to patients as soon as possible."

Key Findings of the Study:

The multimodal deep learning algorithm achieved high sensitivity for CRC detection, ranging from 80.2% to 84.0% across all stages.
The algorithm also demonstrated promising accuracy in detecting AA lesions, with a sensitivity of 63.0%.
The use of colonoscopy-verified normal samples strengthens the study’s foundation and paves the way for future clinical translation.

Efficacy & Durability of OriCAR-017 in RRMM Patients
The updated data demonstrates that OriCAR-017 elicits deep and durable responses in RRMM patients as well as a favorable safety profile, including those refractory to anti-CD38 therapies, PIs, IMIDs, and those who have failed BCMA targeting CAR-T treatment. The long-term efficacy and safety follow-up results support OriCAR-017 as a promising therapeutic approach for RRMM. Currently, Oricell is smoothly advancing the clinical development of OriCAR-017 in both China (NCT06182696) and the United States (NCT06271252).

As of January 16, 2024, all ten patients responded well to OriCAR-017, with the last patient having completed a 24-month follow-up. The overall response rate (ORR) was 100.0%, with a stringent complete response rate (sCR) of 80.0% and a very good partial response rate (VGPR) of 20.0%. All patients achieved 100% minimal residual disease negativity (MRD) at day 28, which was further confirmed as 100% negative at the 3-months follow-up. The median duration of response (mDoR) was 10.43 months (95% CI, 5.00-17.00), the median progression-free survival (mPFS) was 11.37 months (95% CI, 5.93-18.00), and the median overall survival (mOS) had not yet been reached (7 patients were still under survival follow-up, 1 patient died due to disease progression, and 2 patients died from COVID-19). In the high-dose group, where 67% of patients were previously treated with BCMA CAR-T, the mDoR was 17.23 months (95% CI, 7.33-NR), and the mPFS was 19.10 months (95% CI, 8.30-NR). Currently, a BCMA CAR-T-treated patient is still in remission (>24 months).

Safety Profile of OriCAR-017 in the Treatment of RRMM
The therapy was well-tolerated, with 9 out of 10 patients (90%) experiencing Grade 1 cytokine release syndrome (CRS) and only 1 patient (10%) experiencing Grade 2 CRS. No Grade 3 or higher CRS was observed. The median time to CRS onset was 2 days (range 1-9 days), with a median duration of 6 days (range 3-9 days). No immune effector cell-associated neurotoxicity syndrome (ICANS) or dose-limiting toxicities (DLTs) were observed. There were no serious adverse events (SAEs) or treatment-related deaths, cerebellar disorders, or delayed infections reported.

Pharmacokinetics (PK) of OriCAR-017 in RRMM Patients
There were no pharmacokinetic differences between dose levels, with a Cmax of 7354.7 copies/μL and an AUC0-28 of 68587 copies•day/μg. At high doses, CAR-T cells were still detectable at 9 months, and after 21 months of follow-up, one patient had CAR-T cell expansion above the lower limit of quantitation (LLOQ). Patients with Tlast ≥ 9 months had a longer PFS compared to those with Tlast < 9 months.

G5 Expression in Response to OriCAR-017 Treatment in RRMM
No correlation was observed between antigen expression and therapeutic efficacy. Baseline data from all patients showed positive GPRC5D expression in bone marrow CD138+ plasma cells (MMPC), while 50% of relapsed patients showed downregulated expression detected by flow cytometry.

OriCAR-017 Demonstrates Significant Potential in Severely Progressed RRMM Patients
It’s worth noting that the study included patients with complex and advanced disease characteristics. Among the ten R/R MM patients, 40% had extramedullary disease (EMD), 50% had undergone one or more BCMA-directed CAR-T treatments, 70% had high-risk cytogenetics, 70% were classified as ECOG 2 score status, and 80% were at International Staging System (ISS) stages II & III. OriCAR-017 demonstrates its potential as a safe and efficacious treatment option for RRMM patients, marking a substantial progress in the fight against multiple myeloma and offering hope to those facing demanding health conditions.

"Despite notable advances in treatment, most patients with multiple myeloma will eventually relapse. Patients with advanced disease, especially in the community setting, often have limited access to novel treatment options and existing options have a high treatment burden, including frequent dosing," said Dr. Peter Voorhees, clinical professor of medicine, director of plasma cell disorders, Atrium Health Levine Cancer Institute. "The CERVINO Phase 3 trial is designed to evaluate the efficacy of ABBV-383 with monthly dosing and we look forward to seeing the data as it emerges."

Multiple myeloma is a blood cancer characterized by abnormal proliferation of plasma cells, which can cause end-organ damage and is the second most commonly occurring blood cancer in the world.2 An estimated 176,000 people globally were diagnosed with multiple myeloma in 2020, and 117,000 people died from the disease.3

"The start of the CERVINO Phase 3 trial marks an important step forward in AbbVie’s continued commitment to advance new oncology treatments and elevate the standard of care for blood cancer patients," said Mariana Cota Stirner, M.D., vice president, therapeutic area head oncology, hematology, AbbVie. "ABBV-383 is being evaluated with monthly dosing from the beginning of treatment, with the goal of maximizing treatment simplicity for physicians and patients, if proven in the clinical trials."

About the CERVINO Study

CERVINO (NCT06158841) is a global, Phase 3, multicenter, randomized, open-label, parallel-group study evaluating ABBV-383 in adult patients (≥18 years) with r/r MM and an Eastern Cooperative Oncology Group performance status ≤2 who received at least two prior lines of therapy, including exposure to a PI, an IMiD, and an anti-CD38 mAb. Patients who received prior BCMA-targeted therapy will be excluded. Patients will be randomized 1:1 to receive intravenous ABBV-383 60mg Q4W or the investigator’s choice of SAT (carfilzomib + dexamethasone, elotuzumab + pomalidomide + dexamethasone, or selinexor + bortezomib + dexamethasone), and will continue treatment until confirmed progressive disease or other discontinuation criteria are met.

The dual primary end points are progression-free survival and overall response rate. Secondary end points include overall survival, complete response (CR) or better, very good partial response or better, rate of minimum residual disease negativity, and change in disease symptoms and physical functioning.

Approximately 140 sites globally will enroll approximately 380 total patients.

Additional information about the study can be found at View Source under the identifier NCT06158841.

About ABBV-383

ABBV-383 is an investigational distinctive BCMA x CD3 bispecific antibody T-cell engager composed of bivalent high-avidity BCMA-binding domains, a low-affinity CD3-binding domain designed to reduce cytokine release, and a silenced Fc tail designed for an extended half-life that may support once every 4-week (Q4W) dosing. Clinical relevance of these structure activity relationships has not been established.

BCMA is highly expressed on the surface of malignant plasma cells in multiple myeloma, making it an ideal target for therapy. BCMA plays a crucial role in the survival of myeloma cells by promoting their growth and inhibiting their apoptosis (programmed cell death).
