SOUTH SAN FRANCISCO, Calif., Jan 10, 2022 (GLOBE NEWSWIRE via COMTEX) -- SOUTH SAN FRANCISCO, Calif., Jan. 10, 2022 (GLOBE NEWSWIRE) -- ALX Oncology Holdings Inc., ("ALX Oncology") /zigman2/quotes/219511930/composite ALXO -6.97% a clinical-stage immuno-oncology company developing therapies that block the CD47 checkpoint pathway, today provided a corporate update and highlighted key milestones anticipated in 2022.
"2021 was a year of substantial corporate and clinical accomplishments for ALX Oncology. We initiated numerous clinical trials, including two Phase 2 trials in head and neck squamous cell carcinoma ("HNSCC") and presented encouraging Phase 1b data from the ASPEN-01 trial in gastric/gastroesophageal junction ("GEJ") cancer and HNSCC, along with early Phase 1b data from the ASPEN-02 trial in myelodysplastic syndromes ("MDS")," said Jaume Pons, Ph.D., Founder, President and Chief Executive Officer of ALX Oncology.
"On the business development front, we collaborated with Tallac Therapeutics to jointly develop, manufacture, and commercialize a novel toll-like receptor nine agonist antibody conjugate, and late last year we acquired privately held ScalmiBio, giving us full access to their proprietary SHIELD platform for conditional activation of antibodies in the tumor microenvironment and proprietary cytotoxic payloads for antibody-drug conjugates. We expect 2022 to be an exciting and productive year with multiple clinical trial initiations and data readouts for evorpacept," Dr. Pons continued.
Accomplishments in 2021
Presented initial Phase 1a clinical data of evorpacept in combination with azacitidine in patients with MDS (ASPEN-02) at ASH. Accrual is ongoing in the Phase 1 dose expansion part of the study.
Presented updated Phase 1b clinical trial data of evorpacept in combination with pembrolizumab with and without chemotherapy in patients with HNSCC and evorpacept in combination with trastuzumab, ramucirumab, and paclitaxel in patients with gastric/GEJ cancer (ASPEN-01) at SITC.
Initiated a Phase 1a clinical trial of evorpacept in combination with azacitidine and venetoclax in acute myeloid leukemia ("AML") (ASPEN-05).
Acquired privately held ScalmiBio, giving ALX Oncology full access to their proprietary SHIELD platform for conditional activation of antibodies in the tumor microenvironment and proprietary cytotoxic payloads for antibody drug conjugates.
Initiated a Phase 1b/2 clinical trial of evorpacept in combination with zanidatamab in patients with advanced HER2-positive breast cancer, HER2-low breast cancer and additional non-breast HER2-expressing solid tumors being conducted by Zymeworks /zigman2/quotes/208104417/composite ZYME -4.89% .
Entered into a clinical trial collaboration and supply agreement with Eli Lilly /zigman2/quotes/200106384/composite LLY -0.87% to evaluate the combination of evorpacept and CYRAMZA [(R)] (ramucirumab), Eli Lilly's anti-VEGFR2 antibody, for the treatment of patients with HER2-positive gastric/GEJ cancer.
Initiated two randomized Phase 2 studies of evorpacept in combination with KEYTRUDA [(R)] (pembrolizumab) in patients with HNSCC. The first study (ASPEN-03) evaluated the efficacy of evorpacept in combination with pembrolizumab for the first line treatment of patients with PD-L1 expressing metastatic or unresectable, recurrent HNSCC. The second study (ASPEN-04) evaluated evorpacept in combination with pembrolizumab and standard chemotherapy for the first line treatment of patients with metastatic or unresectable, recurrent HNSCC.
Entered into a collaboration with Tallac Therapeutics, a privately held biopharmaceutical company harnessing the power of innate and adaptive immunity to fight cancer to jointly develop, manufacture and commercialize a novel class of cancer immunotherapeutics.
Anticipated Milestones in 2022
Initiation of a randomized Phase 2/3 clinical trial of evorpacept in combination with Herceptin [(R)] (trastuzumab), Cyramza [(R)] (ramucirumab) and paclitaxel in patients with 2nd line or greater gastric/GEJ cancer (ASPEN-06).
Dose optimization readout of a Phase 1b clinical trial of evorpacept in combination with azacitidine in patients with MDS (ASPEN-02).
Add to and report on investigator sponsored clinical trials with evorpacept (non-Hodgkin's lymphoma).
