The PSA reduction for part II patients was in line with the expected pattern for Liproca Depot’s sustained release and maximum PSA reduction (PSA nadir) occurred during months 2-4. The patients in part II showed a strong PSA decrease and a continued PSA reduction at month 5 as well as over the full study period of six months, confirming the NanoZolid technology’s sustained release profile.

67 % of patients receiving 16 ml dose were determined as responders. A responder is defined as a patient experiencing a PSA decrease of 15% or more. 90% of patients who received a 16 ml injection experienced a PSA decrease during their Liproca Depot treatment.

The positive preliminary results show Liproca Depot’s ability to reduce PSA levels over a period of six months, proving the NanoZolid technology´s suitability for local cancer treatment. The study also confirms the technology’s favorable toxicity and tolerability profile.

All patients in the study were under Active Surveillance with low or intermediate risk of cancer progression and these patients currently receive no treatment.

– Patients under Active Surveillance have a risk of cancer progression which places additional stress on them. Liproca Depot could provide an option for physicians to address an unmet medical need, says Anders Bjartell, Professor and Senior Consultant at the Department of Urology, Skåne University Hospital, and LIDDS Board Member.

– Liproca Depot was well tolerated without the hormonal side effects associated with anti-androgen therapies and a majority of patients in the study were positive to receiving a second injection. Administering Liproca Depot is similar to performing a prostate biopsy, says Professor Laurence Klotz, a world leading expert and one of the study investigators and Professor at the University of Toronto Division of Urology.

– These results validate the continued clinical development of Liproca Depot. LIDDS has already signed a license agreement for China with the pharmaceutical company Jiangxi Puheng which plans to conduct and finance a Phase III study. LIDDS will now continue the commercial activities in order to sign further licensing agreements in other major markets, says Monica Wallter, CEO, LIDDS.

Professor Klotz will present the Phase IIb study results in detail at the 11th European Multidisciplinary Congress on Urological Cancers (EMUC19) in Vienna, Austria, on November 16, 2019. A paper reporting the results of the Phase IIb study will be submitted to leading scientific journals for publication.

"AMV564 is a T cell engager that selectively eliminates myeloid-derived suppressor cells (MDSC) in cancer patients while sparing normal neutrophils and monocytes. Its unique activity and excellent safety profile positions AMV564 well, as monotherapy or in combination with other agents, for the treatment of hematologic malignancies and solid tumors," said Jeanmarie Guenot, Ph.D., Amphivena Chief Executive Officer and President.

"The Series C financing is an endorsement by new and existing investors of our leadership in the evolving T cell engagement space," said Peter Van Vlasselaer, Ph.D., Executive Chairman. "This funding enables us to study the therapeutic impact of selective MDSC removal in both hematologic and solid cancers and to advance AMV564 and our novel T cell engagement portfolio to the forefront of immuno-oncology."

About AMV564

AMV564 is a bivalent, bispecific (2:2) T cell engager that binds CD33 and CD3. To date, over 50 patients have received AMV564 in two Phase 1 clinical trials for acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS). It is currently being evaluated in a First-in-Human Phase 1 trial in patients with relapsed/refractory AML at Washington University School of Medicine, MD Anderson Cancer Center, New York-Presbyterian/Weill Cornell Medical Center and Weill Cornell Medicine, Fred Hutchinson Cancer Research Center, The Ohio State University Wexner Medical Center, University of Pennsylvania Medical Center, Northwestern Memorial Hospital, and The Johns Hopkins Hospital.

The safety, efficacy and selectivity of AMV564 was highlighted most recently at both the 24th European Hematology Association (EHA) (Free EHA Whitepaper) meeting in Amsterdam (Abstract S877) and at the 60th Annual Meeting of the American Society of Hematology (ASH) (Free ASH Whitepaper) in San Diego, CA last December. Amphivena believes that AMV564 has demonstrated novel clinical activity by rapidly and selectively eliminating leukemic blasts and rare immature, granulocytic and monocytic MDSCs while sparing normal CD33-expressing cells, including neutrophils and monocytes.

AMV564 is also being evaluated in a Phase 1 solid tumor study which is currently open to enrollment.

AIM ImmunoTech Inc. Announces a Second DoD Award, This One of $8.3 Million, to Fund Phase 2 Clinical Trial to Study Ampligen as Part of a New Treatment for Brain-Metastatic Breast Cancer at the Moffitt Cancer Center

On September 24, 2019 AIM ImmunoTech (NYSE American: AIM), an immuno-pharma company focused on the research and development of therapeutics to treat multiple types of cancers, reported the U.S. Department of Defense (DoD) has granted $8.32 million in funding in another "Breakthrough Award (Press release, AIM ImmunoTech, SEP 24, 2019, View Source [SID1234539736])". This award is to Moffitt Cancer Center for a Phase 2 clinical study of a combination of therapies, including the Company’s drug Ampligen, in patients with brain-metastatic breast cancer (BMBC).

The funding is through the DoD’s Breast Cancer Research Program, which started the Breakthrough Awards to support research that has the potential for a major impact and to accelerate progress toward ending breast cancer. As recently announced, Roswell Park Comprehensive Cancer Center (Roswell Park) reported receipt of its own DoD-funded Breakthrough Award of $6.42 million to study Ampligen in the treatment of BMBC. Together, these separate but parallel proposed clinical trials are receiving approximately $15 million in DoD funding to study Ampligen as a tumor microenvironment modulating agent component of a dendritic cell vaccine approach in the treatment of brain-metastatic breast cancer, which include both brain parenchyma and leptomeningeal sites of metastasis.

The grant to Moffitt Cancer Center was made possible by the unique complementary preclinical and clinical expertise of the teams of Dr. Brian Czerniecki of Moffitt Cancer Center and Dr. Pawel Kalinski of Roswell Park. The researchers hypothesize that vaccination with HER2/HER3-loaded dendritic cells (alpha-DC1s) combined with tumor-selective chemokine modulation (CKM) will be clinically effective and may enhance antitumor efficacy of PD-1 blockade when treating BMBC. Ampligen is a component of CKM therapy.

"Treatment of brain metastasis to the central nervous system is a large need for women with metastatic breast cancer and this novel immunotherapy offers promise to this group of patients," said Dr. Czerniecki, chair of the Department of Breast Oncology at Moffitt Cancer Center.

The researchers’ submitted impact statement highlights this need: "The current treatments, such as surgery or radiotherapy (whole-brain radiation or stereotactic radio-surgery), or intrathecal (I.T.) chemotherapy, constitute a significant burden for patients and do not prevent recurrence and death. The proposed immune therapy will provide new treatment options for these patients who currently face a very grim prognosis."

"These combination therapies are designed to convert ‘cold’ tumors that don’t respond well to existing immune therapies into ‘hot’ tumors that are more susceptible to targeting by immune therapies," said Equels. "We are honored to have Ampligen evaluated as part of a combination therapy in brain-metastatic breast cancer in this DoD-funded comprehensive clinical trial at Central Florida-based Moffitt Cancer Center, one of the world’s premier breast cancer research centers. Brain-metastatic breast cancer is a devastating illness with very poor prognosis, and we are hopeful that Ampligen will play a major role in providing hope to these patients."
