"The completion of enrollment of the AGI-134 first-in-man study is a very significant milestone for our Company, especially taking into account the difficulties caused by the COVID-19 pandemic on patient recruitment," stated Philip Serlin, Chief Executive Officer of BioLineRx. "AGI-134, our second clinical-stage oncology asset, has a unique mode of action, applicable to all injectable tumor types. In preclinical models, AGI-134 led to regression of primary tumors, prevented growth of secondary tumors via an abscopal effect, and triggered a vaccine effect that we believe may prevent the development of metastases. This clinical study aims to confirm the proposed mechanism of action and safety profile of AGI-134 in humans, based on which we also plan to explore potential combinations as part of its future clinical development program."

The Phase 1/2a study is a multicenter, open-label study, which recruited a total of 38 patients in the UK, Spain and Israel, and is comprised of two parts. Part 1 was completed, and was an accelerated dose-escalation study in five patients, to determine the maximum tolerated dose and the recommended dose for part 2 of the study. Part 2 is a dose expansion study at the recommended dose in 33 patients, designed to evaluate the safety and tolerability of AGI-134, and to validate AGI-134’s mechanism of action using a wide array of biomarkers. For more information on this Phase 1/2a study, see NCT03593226.

On December 15, BioLineRx announced the formation of an Immuno-Oncology Scientific Advisory Board (SAB) to provide insight and guidance on the Company’s immuno-oncology activities. The SAB, which has provided valuable guidance to the AGI-134 development program, is comprised of recognized key opinion leaders in the fields of cancer immunology, intra-tumoral cancer treatments and clinical development.

About AGI-134
AGI-134 is a synthetic alpha-Gal glycolipid in development for solid tumors that is highly differentiated from other cancer immunotherapies. AGI-134 is designed to label cancer cells with alpha-Gal via intra-tumoral administration, thereby targeting the body’s pre-existing, highly abundant anti-alpha-Gal (anti-Gal) antibodies and redirecting them to treated tumors. Binding of anti-Gal antibodies to the treated tumors results in activation of the complement cascade, which destroys the tumor cells and creates a pro-inflammatory tumor microenvironment that also induces a systemic, specific anti-tumor (vaccine) response to the patient’s own tumor neo-antigens.

AGI-134 has been evaluated in numerous pre-clinical studies. In a mouse melanoma model, treatment with AGI-134 led to regression of established primary tumors and suppression of secondary tumor (metastases) development. Synergy has also been demonstrated in additional pre-clinical studies when combined with an anti-PD-1 immune checkpoint inhibitor, offering the potential to broaden the utility of such immunotherapies, and improve the rate and duration of responses in multiple cancer types. AGI-134 was obtained by BioLineRx through the acquisition of Agalimmune Ltd.

Panbela Presents Clinical Data on Phase 1b Clinical Trial of SBP-101 in Combination with Gemcitabine and Nab-Paclitaxel in Patients with Metastatic PDA at 2022 ASCO GI Meeting

On January 23, 2022 Panbela Therapeutics, Inc. (Nasdaq: PBLA), a clinical stage biopharmaceutical company developing disruptive therapeutics for the treatment of patients with cancer reported the presentation of interim clinical data from its Phase 1b combination therapy study of SBP-101, a proprietary polyamine analogue, with gemcitabine and nab-paclitaxel in patients with metastatic pancreatic ductal adenocarcinoma (PDA), at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Gastrointestinal (GI) Meeting that took place January 20-22, 2022 (Press release, Panbela Therapeutics, JAN 23, 2022, View Source [SID1234606716]).

Jennifer K. Simpson, PhD, MSN, CRNP President & Chief Executive Officer of Panbela Therapeutics, commented, "We are excited to share interim data from cohort 4 and the expansion. A median overall survival (OS) of 12.0 months which is not yet final, and an objective response rate (ORR) of 48%, both exceeded historical rates reported for gemcitabine + nab paclitaxel and supports the continued development of SBP-101 as an addition to first-line treatment for advanced PDA and as neo-adjuvant treatment for patients with potentially resectable disease."

"The conclusion of the abstract is that SBP-101 may enhance first-line treatment with gemcitabine and nab-paclitaxel patients with metastatic PDA. We are encouraged by this conclusion even under sub-optimal conditions, including dose interruptions, which confounded results. Cohorts 2 and 3 did not have the dose interruptions that cohort 4 had, and cohort 2 had an objective response rate of 71%," continued Dr. Simpson. "We intend to continue development of SBP-101 and look forward to executing our global randomized phase 2 study in metastatic PDA."

At the Phase 1b dose and schedule (N=30), CA19-9 levels decreased 60-99% in 70% of evaluable patients, with 1/29 (3%) achieving a complete remission, 13/29 evaluable patients achieving partial responses (45%) and 10/29 achieving stable disease at 8 weeks (34%). PFS was 6.0 months. While PFS may be confounded by SBP-101 dosing holds implemented to investigate potential toxicity, the rates for 6-month PFS was 52% and for 12 month PFS was 10%. Nine subjects are in survival follow up as of the date the poster was presented at the ASCO (Free ASCO Whitepaper) GI meeting. Median OS is 12.0 months and is not final.

The safety population includes all subjects who received at least one dose of SBP-101 (N=50). The most common Grade ≥3 adverse events (AEs) related to any study medication were neutropenia in 20 subjects (19 attributed to G+A and 1 attributed to all 3) and elevated liver function tests in 14 subjects (5 attributed to SBP-101 and 9 attributed to all 3). SBP-101-related increases in LFTs were asymptomatic in all but 2 subjects and reversed in all subjects when SBP-101 administration was interrupted and dose-reduced or discontinued. Additionally, seven subjects experienced serious vision adverse events (4 possibly related to SBP-101, 1 related to gemcitabine and 2 related to all 3 based on PI assessment). All were considered by the sponsor to be possibly related to SBP-101; 5 had findings consistent with retinopathy.

The company has just begun a randomized trial to study SBP-101, as an addition to first-line treatment for metastatic PDA, will begin a neoadjuvant pancreatic trial this quarter and will begin an Ovarian Cancer program mid-year.

Additional meeting information can be found on the ASCO (Free ASCO Whitepaper) website at View Source . After presenting at ASCO (Free ASCO Whitepaper) GI, the poster will be available on the company’s website on January 24, 2022.

About SBP-101
SBP-101 is a proprietary polyamine analogue designed to induce polyamine metabolic inhibition (PMI) by exploiting an observed high affinity of the compound for pancreatic ductal adenocarcinoma and other tumors. The molecule has shown potential signals of tumor growth inhibition in clinical studies of US and Australian metastatic pancreatic cancer patients, suggesting potential complementary activity with an existing FDA-approved standard chemotherapy regimen, if SPB-101 receives approval in the US. In data evaluated from clinical studies to date, SBP-101 has not shown exacerbation of bone marrow suppression and peripheral neuropathy, which can be chemotherapy-related adverse events. Serious visual adverse events observed in the Company’s recently completed Phase 1a/1b clinical trial have been evaluated and patients with a history of retinopathy or at risk of retinal detachment will be excluded from future SBP-101 studies. The safety data and PMI profile observed in the current Panbela sponsored clinical trial provides support for continued evaluation of SBP-101 in a randomized clinical trial.

The Phase III registration study (ClinicalTrials.gov Identifier: NCT05118776) is a randomized, double-blind, placebo-controlled, multi-center clinical trial in China to evaluate progression-free survival (PFS), overall survival (OS) and safety of patients with rGBM. Approximately 180 patients will be 1:1 randomized to Cohort 1 (oral ASC40 tablet once daily + Bevacizumab) and Cohort 2 (matching placebo tablet once daily + Bevacizumab). Approximately 80% of such 180 patients with rGBM in the Phase III clinical trial are expected to be randomized and enrolled by the end of December 2022.

The Phase II study, completed in the U.S., in patients with rGBM has shown that the objective response rate (ORR) for ASC40 plus Bevacizumab treatment was 65% including a complete response (CR) of 20% and a partial response (PR) of 45%.

Based on published data, in China, glioblastoma (GBM) represents 57% of gliomas and has an incidence rate of approximately 2.85 to 4.56 per 100,000 population per year, suggesting approximately 40,000 to 64,000 new cases of GBM per year. More than 90% GBM patients will relapse after surgery, radiation and chemotherapies. In the U.S., GBM represents 56.6% of gliomas and has an incidence rate of approximately 3.21 per 100,000 population per year.

"I am pleased that the first patient has been successfully dosed in the Phase III clinical trial of ASC40 combined with bevacizumab for treatment of recurrent glioblastoma. As the first clinical trial targeting tumor lipid metabolism in China, we are looking forward to the results of the trial," said Dr. Wenbin Li, Vice Chairman and Secretary General of Glioma Committee of Chinese Cancer Association, Director of the Comprehensive Tumor Treatment Center, Beijing Tiantan Hospital, Capital Medical University.

"Dosing the first patient in ASC40 Phase III registration study is a significant milestone for our oncology pipeline. We are looking forward to the data from this Phase III study," said Dr. Jinzi J. Wu, Founder, Chairman and CEO of Ascletis.

In Ascletis’ oncology pipeline, in addition to FASN inhibitors, there are two oral PD-L1 small molecule inhibitors developed in-house, namely ASC61 and ASC63. Ascletis has filed a U.S. Investigational New Drug (IND) application of ASC61 for the treatment of advanced solid tumors.
