Figure 1 is the new data published yesterday evening at SABCS, which shows that GP2 immune response at baseline could be a prognosticator of cancer recurrence. The Phase IIb clinical trial enrolled HER2 positive patients, who received a standard course of trastuzumab after surgery, and HER2 low patients, who did not receive trastuzumab after surgery. A Delayed-Type Hypersensitivity (DTH) reaction was used to assess baseline in vivo immune responses to GP2 in patients prior to exposure to GP2 treatment or placebo.

The poster data can be summarized as follows:

‒ It was observed that 22.8% or 33 patients of the 145 patients reacted to GP2 at baseline with a positive immune response, which is defined as an induration of 5 mm or greater in the baseline DTH test.

‒ Of the 33 patients who did have a positive baseline DTH immune response to GP2, 8 patients recurred, which is a recurrence rate of 24.2% over 5 years of follow up, with a median time to recurrence of 99 days (0.27 years).

‒ Of the 77.2% or 112 patients who did not have a positive DTH baseline immune response to GP2, 14 patients recurred, which is a recurrence rate of 12.5% over 5 years of follow up, with a median time to recurrence of 438 days (1.2 years).

Mr. Patel commented, "This new GP2 specific T cell data suggests that patients with a positive baseline immune response to GP2 recurred twice as fast and approximately 7 to 11 months sooner than those without a positive baseline immune response did. While this data is very promising, the number of recurrences are low, thus we need to further confirm these observations in the upcoming Phase III clinical trial to determine if they are statistically significant. To further diversify our pipeline, we plan to fully characterize GP2 specific T cells by sequencing the DNA of the T cells at baseline and after treatment with GP2 to assess how these T cells change over time and if they can be developed into CAR-T drug candidates. Expansion into GP2 specific CAR-T cells could potentially become another platform technology to complement GP2 peptide treatment in higher risk patients. We expect new T cell data from the Phase III trial to become available in 2022."

Today is the one year anniversary of the Company’s SABCS 2020 poster, which became the basis for Figure 2. This figure summarizes the efficacy, immune response, and safety Phase IIb data presented over the past year. The Kaplan Meier analysis for HER2 positive patients treated with GP2 immunotherapy shows 100% disease free survival (0% breast cancer recurrences, p = 0.0338) following surgery and Herceptin treatment over median 5 years of follow-up. These patients completed the Primary Immunization Series (PIS) which led to peak immunity at 6 months. No serious adverse events attributable to GLSI-100 were observed. Figure 1 and Figure 2 summarize all of the 5 year GP2 data published to date.

SABCS Abstract P2-13-29:

Title: Analysis of GP2 immune response and relationship to recurrence in a prospective, randomized, placebo-controlled, single-blinded, multicenter, phase IIb study evaluating the reduction of recurrences using HER2/neu peptide GP2 (GLSI-100) vs. GM-CSF alone after adjuvant trastuzumab in HER2 positive women with operable breast cancer

Background: Delayed type hypersensitivity (DTH) skin tests in the randomized, active-controlled, single-blinded, multicenter Phase IIb trial investigating GLSI-100 (GP2+GM-CSF) administered in the adjuvant setting to node-positive and high-risk node-negative breast cancer patients with tumors expressing any degree of HER2 (immuno-histochemistry [IHC] 1-3+) (NCT00524277) have been analyzed. The trial enrolled HLA-A*02 patients randomized to receive GLSI-100 versus GM-CSF alone. The trial’s primary objective was to determine if treatment with GLSI-100, a HER2-derived peptide, reduces recurrence rates. Analyses for this trial showing GLSI-100 to be efficacious, safe and immunogenic have been previously reported by Patel et al. and Mittendorf et al.

Methods: Consented patients were randomized and scheduled to receive GLSI-100 (500 mcg GP2: 125 mcg GM-CSF) or control (GM-CSF only) via 6 intradermal injections every 3-4 weeks as part of the Primary Immunization Series (PIS) for the first 6 months and 4 booster intradermal injections every 6 months thereafter. Boosters were introduced during the trial, thus some patients did not receive all 4 boosters. DTH skin tests were assessed at baseline and after the 6th dose with the orthogonal mean of each skin reaction measured 48-72 hours after injection using the sensitive ballpoint-pen method.

Results: The study enrolled 180 patients across 16 clinical sites with both HER2 3+ positive and low HER2 expressors (1-2+). After 5 years of follow-up, the Kaplan-Meier estimated 5-year DFS rate in the 46 HER2 3+ patients treated with GLSI-100, if the patient completed the PIS, was 100% versus 89.4% (95% CI:76.2, 95.5%) in the 50 placebo patients treated with GM-CSF (p = 0.0338). GLSI-100 was shown to be well tolerated with no SAEs deemed related to study medication and elicited a potent immune response measured by local skin tests and immunological assays. Injection site reactions were common, occurring in almost 100% of patients treated with either GLSI-100 or GM-CSF alone. Previous publications have reported the increase in DTH response reported among patients after treatment with GLSI-100. However, it was of interest to understand the positive DTH responses to GP2 noted at baseline. 22.8% of patients reacted to GP2 at baseline with induration of 5mm or greater. In the subgroup of patients who later experienced a breast cancer recurrence, 36.4% (8/22) had such a baseline response. Analysis of the time to recurrence among those recurring found that the median time to recurrence was 0.6 years for those with a baseline response while those that did not have a positive baseline DTH response to GP2 took 1.2 years to recur.

Conclusions: This study demonstrated that GLSI-100 safely elicited a potent immune response as evidenced by increased DTH skin responses with treatment paired with improved disease-free survival. It is theorized that a positive baseline DTH skin test to GP2 may be evidence of an existing immune response to GP2 associated with residual disease, impending recurrence, or prior treatments. Further studies assessing if GP2 immune response is an important prognosticator of cancer disease state or recurrence are planned.

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.

Totus Medicines’ TOS-358 drug program targets the PI3Kα mutation, which impacts more than 500,000 people in the U.S. every year and drives a significant percentage of breast, colon, lung, bladder, stomach, and other cancers. The pharmaceutical industry has spent decades and billions of dollars attempting to target PI3Kα, and current inhibitors only achieve moderate success in <10% of patients with PI3Kα-mutant cancers.

In just 18 months, Totus has used its proprietary drug discovery platform to develop TOS-358, which shows strong preclinical efficacy across PI3Kα-mutant tumor types where current PI3Kα inhibitors show weak to no efficacy. In patient-derived mouse xenograft models, TOS-358 induces tumor regressions across breast, colon, lung, stomach, and other models, while current inhibitors show mild effects. Totus Medicines will begin clinical trials for the TOS-358 drug program in the second half of 2022.

"Our drug discovery platform is capable of creating treatments for previously untreatable diseases," said Neil Dhawan, Ph.D., co-founder and CEO of Totus Medicines. "We are drugging undruggable targets at scale, moving us closer to a world where every physician and every patient can look forward to effective treatments for the most devastating illnesses. The TOS-358 drug program is a crowning achievement in that mission, and we look forward to advancing the program—and many others—into the clinic."

Totus Medicines’ platform uses proprietary molecular tags that track drug binding in individual cells to screen billions of drug molecules across thousands of genes in parallel. By combining this approach with breakthrough machine learning techniques, the company has developed the next generation of cellular analysis. Continuously learning and adapting, the Totus platform is more effective, less costly, and thousands of times faster than legacy drug discovery methods, enabling the rapid translation of therapies to patients. Totus aims to screen two billion compounds across the human genome within the next two years to unlock precise, effective drugs across hundreds of high-value drug targets.

"The Series A financing will allow us to refine and grow the Totus platform to find new treatments for previously untreatable diseases—faster and more successfully than has ever been possible," said Jason Pontin, a Partner at DCVC, and a board member and co-founder of Totus Medicines. "The promise of Totus Medicines is that doctors can offer life-changing medicines to patients who would otherwise have little hope."

About FAP-2286

FAP-2286 is a clinical candidate under investigation as a peptide-targeted radionuclide therapy (PTRT) and imaging agent targeting fibroblast activation protein (FAP). FAP-2286 consists of two functional elements; a targeting peptide that binds to FAP and a site that can be used to attach radioactive isotopes for imaging and therapeutic use. High FAP expression has been shown in pancreatic ductal adenocarcinoma, salivary gland, mesothelioma, colon, bladder, sarcoma, squamous non-small cell lung, squamous head and neck cancers, and cancers of unknown primary. High FAP expression was detected in both primary and metastatic tumor samples and was independent of tumor stage or grade. Clovis holds US and global rights for FAP-2286 excluding Europe, Russia, Turkey, and Israel.

FAP-2286 is an unlicensed medical product.

About Targeted Radionuclide Therapy

Targeted radionuclide therapy is an emerging class of cancer therapeutics, which seeks to deliver radiation directly to the tumor while minimizing delivery of radiation to normal tissue. Targeted radionuclides are created by linking radioactive isotopes, also known as radionuclides, to targeting molecules (e.g., peptides, antibodies, small molecules) that can bind specifically to tumor cells or other cells in the tumor environment. Based on the radioactive isotope selected, the resulting agent can be used to image and/or treat certain types of cancer. Agents that can be adapted for both therapeutic and imaging use are known as "theranostics." Clovis, together with licensing partner 3B Pharmaceuticals, is developing a pipeline of novel, targeted radiotherapies for cancer treatment and imaging, including its lead candidate, FAP-2286, an investigational peptide-targeted radionuclide therapeutic (PTRT) and imaging agent, as well as three additional discovery-stage compounds.

About the LuMIERE Clinical Study

LuMIERE is a Phase 1/2 study evaluating FAP-2286 as a peptide-targeted radionuclide therapy (PTRT) targeting fibroblast activation protein, or FAP, in patients with advanced solid tumors (NCT04939610). The Phase 1 portion of the LuMIERE study is evaluating the safety of the investigational therapeutic agent and will identify the recommended Phase 2 dose and schedule of lutetium-177 labeled FAP-2286 (177Lu-FAP-2286). FAP-2286 labeled with gallium-68 (68Ga-FAP-2286) will be utilized as an investigational imaging agent to identify patients with FAP-positive tumors appropriate for treatment with the therapeutic agent. Once the Phase 2 dose is determined, Phase 2 expansion cohorts are planned in multiple tumor types.

On December 9, 2021 AstraZeneca reported that New results from the DESTINY-Breast03 Phase III trial showed that Enhertu (trastuzumab deruxtecan) demonstrated a higher progression-free survival (PFS) and objective response rate (ORR) in pre-specified patient subgroups compared to trastuzumab emtansine (T-DM1) in patients with HER2-positive unresectable and/or metastatic breast cancer previously treated with trastuzumab and a taxane (Press release, AstraZeneca, DEC 9, 2021, View Source [SID1234596655]).

Enhertu is a HER2-directed antibody drug conjugate (ADC) being jointly developed by AstraZeneca and Daiichi Sankyo Company, Limited (hereafter, Daiichi Sankyo).

A similar PFS and ORR benefit was observed in exploratory analyses in patients defined by stable brain metastases, hormone receptor status, number of prior lines of therapy, prior pertuzumab treatment, or status of visceral metastasis. Results were presented in an oral presentation at the 2021 San Antonio Breast Cancer Symposium (SABCS).

In patients with stable brain metastases at baseline, treatment with Enhertu resulted in higher PFS compared to T-DM1 (PFS by blinded independent central review (BICR) hazard ratio [HR] 0.25; 95% confidence interval [CI] 0.13-0.45). Additionally, in this subgroup, Enhertu improved PFS to a median of 15 months versus 3 months for T-DM1.

Sara Hurvitz, MD, FACP, medical oncologist, professor of medicine, and director of the Breast Cancer Clinical Trials Program in the division of hematology-oncology at the David Geffen School of Medicine at UCLA, and medical director for the Clinical Research Unit at the UCLA Jonsson Comprehensive Cancer Center in Santa Monica, CA, said: "The main goals in the treatment of HER2-positive metastatic breast cancer, including those with stable brain metastases are to improve symptoms, stabilise or reduce the tumour size and improve overall survival. The higher progression-free survival seen in DESTINY-Breast03 in the subgroup of patients with stable brain metastases are encouraging, and underscores the excitement around another potential treatment option for patients who have experienced disease progression on currently available therapies."

Susan Galbraith, Executive Vice President, Oncology R&D, AstraZeneca, said: "More treatment options are needed to delay progression and extend survival for patients with HER2-positive metastatic breast cancer who develop brain metastases. These additional analyses from DESTINY-Breast03 reinforce the potential of Enhertu with similar benefits in the different subgroups."

Ken Takeshita, Global Head, R&D, Daiichi Sankyo, said: "These additional analyses from DESTINY-Breast03 continue to demonstrate the benefit of Enhertu compared to T-DM1 in patient subgroups, including 15-month progression-free survival in those with stable brain metastases, illustrating the potential of this treatment to become the new standard of care in patients with previously treated HER2-positive metastatic breast cancer. These data will support our ongoing conversations with global health authorities to realise our commitment to bring Enhertu to patients with previously treated HER2-positive breast cancer earlier in the metastatic setting."

Between 30 to 50% of patients with HER2-positive metastatic breast cancer will develop brain metastases, and while increased availability of HER2 therapies has improved systemic disease control, prognosis following the development of brain metastases remains poor.1-5

Confirmed ORR for patients with stable brain metastases at baseline was 67.4% with Enhertu versus 20.5% with T-DM1. A retrospective, non-prespecified evaluation of intracranial response among patients with stable brain metastases who received scans at baseline provided preliminary evidence that treatment with Enhertu is associated with intracranial tumour response and reduction in Central Nervous System disease with 10 (27.8%) complete responses (CR) and 13 (36.1%) partial responses (PR) compared to one (2.8%) CR and 11 (30.6%) PRs in those treated with T-DM1.

The safety profile of the most common adverse events with Enhertu in DESTINY-Breast03 remains consistent with previous clinical trials of Enhertu in breast cancer with no new safety concerns identified. Adjudicated drug-related interstitial lung disease or pneumonitis was reported in 27 patients (10.5%) treated with Enhertu and five patients (1.9%) treated with T-DM1 overall, with no Grade 4 or 5 events.

Based on the primary results of DESTINY-Breast03, Enhertu received its fourth Breakthrough Therapy Designation (BTD) in the US for the treatment of adult patients with unresectable or metastatic HER2-positive breast cancer who have received one or more prior anti-HER2-based regimens in September 2021.

Enhertu is approved for the treatment of adult patients with unresectable or metastatic HER2-positive breast cancer who have received two or more prior anti-HER2-based regimens in more than 30 countries based on the results from the DESTINY-Breast01 trial.

Enhertu is being further assessed in a comprehensive clinical development programme evaluating efficacy and safety across multiple HER2-targetable cancers, including breast, gastric, lung and colorectal cancers.

Notes

DESTINY-Breast03
DESTINY-Breast03 is a global head-to-head, randomised, open-label, registrational Phase III trial evaluating the safety and efficacy of Enhertu (5.4mg/kg) versus T-DM1 in patients with HER2-positive unresectable and/or metastatic breast cancer previously treated with trastuzumab and a taxane.

The primary efficacy endpoint of DESTINY-Breast03 is PFS based on blinded independent central review. Secondary efficacy endpoints include overall survival, objective response rate, duration of response, PFS based on investigator assessment and safety.

DESTINY-Breast03 enrolled approximately 500 patients at multiple sites in Asia, Europe, North America, Oceania and South America. For more information about the trial, visit ClinicalTrials.gov.

HER2-positive breast cancer
Breast cancer remains the most common cancer and is one of the leading causes of cancer-related deaths in women worldwide.6 More than two million patients with breast cancer were diagnosed in 2020, resulting in nearly 685,000 deaths globally.6 Approximately one in five cases of breast cancer are considered HER2-positive.7

HER2 is a tyrosine kinase receptor growth-promoting protein expressed on the surface of many types of tumours, including breast, gastric, lung and colorectal cancers.8 HER2 protein overexpression may occur as a result of HER2 gene amplification and is often associated with aggressive disease and a poor prognosis in breast cancer.9

Despite initial treatment with trastuzumab and a taxane, patients with HER2-positive metastatic breast cancer will often experience disease progression.1 Additionally, it is estimated that 30 to 50% of patients will develop brain metastases, and while increased availability of HER2 therapies has improved systemic disease control, prognosis following development of brain metastases remains poor.1-5 More treatment options are needed to further delay progression and extend survival.1-4

Enhertu
Enhertu is a HER2-directed ADC. Designed using Daiichi Sankyo’s proprietary DXd ADC technology, Enhertu is the lead ADC in the oncology portfolio of Daiichi Sankyo and the most advanced programme in AstraZeneca’s ADC scientific platform. Enhertu consists of a HER2 monoclonal antibody attached to a topoisomerase I inhibitor payload, an exatecan derivative, via a stable tetrapeptide-based cleavable linker.

Enhertu (5.4 mg/kg) is approved in more than 30 countries for the treatment of adult patients with unresectable or metastatic HER2-positive breast cancer who have received two or more prior anti-HER2-based regimens in the metastatic setting based on the results from the DESTINY-Breast01 trial.

Enhertu (6.4 mg/kg) is also approved in several countries for the treatment of adult patients with locally advanced or metastatic HER2-positive gastric or gastroesophageal junction adenocarcinoma who have received a prior trastuzumab-based regimen based on the results from the DESTINY-Gastric01 trial.

A Type II Variation is currently under review by the European Medicines Agency (EMA) for the treatment of adult patients with locally advanced or metastatic HER2-positive gastric or gastroesophageal junction adenocarcinoma who have received a prior anti-HER2-based regimen.

Enhertu development programme
A comprehensive development programme is underway globally, evaluating the efficacy and safety of Enhertu monotherapy across multiple HER2-targetable cancers, including breast, gastric, lung and colorectal cancers. Trials in combination with other anticancer treatments, such as immunotherapy, are also underway.

Enhertu was highlighted in the Clinical Cancer Advances 2021 report as one of two significant advancements in the "ASCO Clinical Advance of the Year: Molecular Profiling Driving Progress in GI Cancers," based on data from both the DESTINY-CRC01 and DESTINY-Gastric01 trials, as well as one of the targeted therapy advances of the year in non-small cell lung cancer (NSCLC), based on the interim results of the HER2-mutated cohort of the DESTINY-Lung01 trial.

Enhertu received its fourth BTD in the US, which was for the treatment of adult patients with unresectable or metastatic HER2-positive breast cancer who have received one or more prior anti-HER2-based regimens.

Daiichi Sankyo collaboration
Daiichi Sankyo and AstraZeneca entered into a global collaboration to jointly develop and commercialise Enhertu (a HER2-directed ADC) in March 2019, and datopotamab deruxtecan (DS-1062; a TROP2-directed ADC) in July 2020, except in Japan where Daiichi Sankyo maintains exclusive rights. Daiichi Sankyo is responsible for manufacturing and supply of Enhertu and datopotamab deruxtecan.

AstraZeneca in breast cancer
Driven by a growing understanding of breast cancer biology, AstraZeneca is starting to challenge, and redefine, the current clinical paradigm for how breast cancer is classified and treated to deliver even more effective treatments to patients in need – with the bold ambition to one day eliminate breast cancer as a cause of death.

AstraZeneca has a comprehensive portfolio of approved and promising compounds in development that leverage different mechanisms of action to address the biologically diverse breast cancer tumour environment. AstraZeneca aims to continue to transform outcomes for HR-positive breast cancer with foundational medicines Faslodex (fulvestrant) and Zoladex (goserelin) and investigational agents next-generation oral SERD and camizestrant.

PARP inhibitor Lynparza (olaparib) is a targeted treatment option for metastatic breast cancer patients with an inherited BRCA mutation. AstraZeneca with MSD (Merck & Co., Inc. in the US and Canada) continue to research Lynparza in metastatic breast cancer patients with an inherited BRCA mutation and are exploring new opportunities to treat these patients earlier in their disease.

Building on the first approval of Enhertu, a HER2-directed ADC, in previously treated HER2-positive metastatic breast cancer, AstraZeneca and Daiichi Sankyo are exploring its potential in earlier lines of treatment and in new breast cancer settings.

To bring much needed treatment options to patients with triple-negative breast cancer, an aggressive form of breast cancer, AstraZeneca is testing immunotherapy Imfinzi (durvalumab) in combination with other oncology medicines, including Lynparza and Enhertu, evaluating the potential of AKT kinase inhibitor, capivasertib, in combination with chemotherapy, and collaborating with Daiichi Sankyo to explore the potential of TROP2-directed ADC, datopotamab deruxtecan.

AstraZeneca in oncology
AstraZeneca is leading a revolution in oncology with the ambition to provide cures for cancer in every form, following the science to understand cancer and all its complexities to discover, develop and deliver life-changing medicines to patients.

The Company’s focus is on some of the most challenging cancers. It is through persistent innovation that AstraZeneca has built one of the most diverse portfolios and pipelines in the industry, with the potential to catalyse changes in the practice of medicine and transform the patient experience.

AstraZeneca has the vision to redefine cancer care and, one day, eliminate cancer as a cause of death.

On December 9, 2021 Aprea Therapeutics, Inc. (Nasdaq: APRE), a biopharmaceutical company focused on developing and commercializing novel cancer therapeutics that reactivate the mutant tumor suppressor protein, p53, reported that the U.S. Food and Drug Administration (FDA) has removed the full clinical hold on the Company’s clinical trial evaluating the combination of its lead compound, eprenetapopt, with acalabrutinib or with venetoclax and rituximab in lymphoid malignancies (Press release, Aprea, DEC 9, 2021, View Source [SID1234596654]).
