Today at 5:00 pm, the Company’s management team will be presenting two posters at the 2021 San Antonio Breast Cancer Symposium (SABCS) in person. The Company anticipates making the SABCS Phase IIb poster available on its website by the morning of December 9, exactly one year after the 2020 SABCS poster was published showing that no metastatic breast cancer recurrences were observed over 5 years of follow-up in HER2 positive patients who were fully treated. On December 9 at 2:20 pm ET, Snehal Patel, CEO of Greenwich LifeSciences, will appear as a featured guest in a live interview on TD Ameritrade Network’s The Watch List with host Nicole Petallides to discuss the poster.

A second poster at SABCS will provide further design features of the Phase III clinical trial for discussion with attending clinicians. At this hybrid conference the Company will be meeting with clinicians participating in the Phase III trial and with members of the Data Safety Monitoring Board and the Clinical Advisory/Steering Committee, both of which will provide independent oversight of the Phase III trial and will advise the Company on the conduct of the trial. The Company also hosted a dinner to bring the Phase III clinical team together.

An exclusive interview with CEO Snehal Patel was aired a second time on The RedChip Money Report on Bloomberg TV this past Saturday, December 4. In the interview Mr. Patel discusses the Phase IIb clinical trial results, the next steps for the upcoming FLAMINGO-01 Phase III clinical trial, potential Phase IIb and Phase III clinical data publications in 2022, the impact of joining the Russell 2000, and examples of recent comparable strategic transactions in breast cancer and immunotherapy.

During the week of January 10, 2022, Mr. Patel will participate in the following three virtual/hybrid investor conferences:

H.C. Wainwright 2022 BioConnect Conference:

The Company will be participating in the H.C. Wainwright BioConnect Conference with a virtual presentation that will be available on demand.

Biotech Showcase 2022:

The Company will be participating in the Biotech Showcase partnering event with an on-demand presentation available to conference participants and potentially an in-person presentation should conditions permit.

BIO Partnering at JPM:

The Company will be participating in the BIO partnering event at the 2022 JP Morgan Healthcare Conference.

About FLAMINGO-01 and GLSI-100

The Phase III clinical trial will be called FLAMINGO-01 and the combination of GP2 + GM-CSF will be called GLSI-100. The Phase III trial is comprised of 2 blinded, randomized, placebo-controlled arms for approximately 500 HLA-A*02 patients and 1 open label arm of up to 100 patients for all other HLA types. An interim analysis has been designed to detect a hazard ratio of 0.3 in IDFS, where 28 events will be required. An interim analysis for superiority and futility will be conducted when at least half of those events, 14, have occurred. This sample size provides 80% power if the annual rate of events in placebo-treated subjects is 2.4% or greater. The trial is currently being registered on clinicaltrials.gov and the link and trial identifier will be published shortly.

About Breast Cancer and HER2/neu Positivity

One in eight U.S. women will develop invasive breast cancer over her lifetime, with approximately 282,000 new breast cancer patients and 3.8 million breast cancer survivors in 2021. HER2/neu (human epidermal growth factor receptor 2) protein is a cell surface receptor protein that is expressed in a variety of common cancers, including in 75% of breast cancers at low (1+), intermediate (2+), and high (3+ or over-expressor) levels.

Amphera progresses two pancreatic cancer programmes after encouraging initial safety and efficacy data in mesothelioma

On December 8, 2021 Amphera B.V., a late-stage biotechnology company developing MesoPher cell therapy to treat cancer, reported that significant progress in its two clinical programs in pancreatic cancer as well as the full recruitment of all patients in its pivotal Phase II/III study in mesothelioma (Press release, Amphera, DEC 8, 2021, View Source [SID1234596616]).

Based on a preliminary efficacy analysis of the first cohort of the REACtiVe study in resected pancreatic cancer patients, an expansion cohort has been completed at a remarkable pace with results expected in H2 2022. In total 26 patients are now included in the study. Safety and efficacy data from the first cohort of the REACtiVe study in resected pancreatic cancer patients treated with MesoPher have been submitted for publication by Erasmus MC, Rotterdam, the Netherlands.

In addition a study in metastatic pancreatic cancer, REACtiVe-2, has started recruiting patients. This study will assess the safety and efficacy of a combination therapy of MesoPher and mitazalimab (a CD40 agonist from Alligator Bioscience). This follows the strong preclinical data published in the Journal for ImmunoTherapy of Cancer, which established the potency of the combination (available here).

Finally, the company announces that the Phase II/III pivotal study DENIM in mesothelioma patients is fully recruited and confirms the readout to be expected in Q4 2022.

Rob Meijer, CEO of Amphera said: "Over the last year Amphera has made exceptional progress with its clinical development programmes based on its MesoPher cell therapy platform. Despite the challenging pandemic environment, our trials saw strong enrolment, underlying the high medical need for patients. The pivotal Phase II/III DENIM study in pleural mesothelioma has now been fully recruited with the read-out expected in Q4 2022 and we are strongly encouraged by the rapid enrolment of the expansion cohort of the Phase II REACtiVe study in pancreatic cancer. In addition to the studies in pancreatic cancer and pleural mesothelioma, efficacy of MesoPher is investigated in abdominal mesothelioma and pleural mesothelioma in combination with surgical resection."

Prof. Joachim Aerts MD PhD, Medical Advisor to Amphera said: "Efficacy was first proven in mesothelioma and for me, as a clinician and a scientist, it is exciting to see that the previous efficacy found, translates into relevant clinical results for patients in other indications, especially one with a dire prognosis such as pancreatic cancer. We have also recently published highly compelling long-term survival data in Vaccines from three studies in mesothelioma patients (available here). In the three studies combined, the median overall survival was 27 months and the overall survival at 5 years was 21%. The expanding data set is showing the real potential of MesoPher in a wide range of oncology indications."

About H3B-6545
Estrogen receptor alpha (ERα) plays an important oncogenic role in the genesis and progression of luminal breast cancers, and historically has been a target of endocrine therapies. However, recently, hotspot mutations in ERα have been detected in nearly 30% of endocrine-therapy resistant metastases. Functional studies have shown that these ERα mutations can confer ligand-independent activation of the ERα pathway and can promote partial resistance to existing classes of ER-directed therapies. H3B- 6545, a first-in-class small molecule selective estrogen receptor covalent antagonist (SERCA) demonstrates activity in tumor models that harbor wild-type or mutant ERα. H3B-6545 activity against ERα mutants resistant to standard therapy provides an opportunity to target a currently unmet medical need both as a single agent and in combination with other breast cancer therapies.
