The primary objective of the study is to evaluate the safety and tolerability of ATG-018 as monotherapy to determine the appropriate dose for Phase II studies and assess preliminary efficacy, if available; the secondary objective is to characterize the pharmacology of ATG-018.

ATG-018 is an orally available, potent, selective small molecule ATR inhibitor. ATG-018 inhibits the ATR (ataxia telangiectasia mutated and Rad3-related) kinase, thus limiting cancer cells’ ability to repair damaged DNA, in a mechanism also known as synthetic lethality.

Dr. Bo Shan, Chief Scientific Officer of Antengene commented, "ATG-018, one of Antengene’s first in-house programs to reach the clinic, targets the DDR pathway that is deregulated in many cancers. DDR inhibitors represent a promising area of drug development and clinical research in oncology, especially in resistant or advanced diseases. The differentiated profile of ATG-018 may enable it to be used as monotherapy and open the door for novel collaborations and combination regimens that could benefit cancer patients around the world."

Dr. Kevin Lynch, Chief Medical Officer of Antengene continued, "Antengene is very excited to submit the ATG-018 Phase I protocol for HREC review, based on its solid preclinical data package including efficacy as a monotherapy in solid tumor models, oral bio-availability and potential biomarkers. The use of biomarker-informed studies may facilitate clinical trial enrollment and provide an additional tool to monitor patients during the trial. As we prepare for the start of this important study, I want to thank all of the investigator sites for their support and enthusiasm, and everyone in Antengene’s R&D organization for their dedication in the preparation for this study."

About the ATRIUM Trial

The ATRIUM trial is a Phase I multi-center, open-label, dose finding study of ATG-018 monotherapy in patients with advanced solid tumors or hematologic malignancies. The primary objective of the study is to evaluate the safety and tolerability of ATG-018 and to determine the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D) and/or biologically effective dose of ATG-018 monotherapy and preliminary efficacy, if available; the secondary objective is to characterize the pharmacology of ATG-018. As a Phase I study, there will be intensive safety monitoring throughout the trial.

About ATG-018

Developed by the internal R&D Team at Antengene, ATG-018 is an oral, potent, selective small molecule inhibitor targeting ataxia telangiectasia and Rad3-related (ATR) kinase. ATR kinase belongs to the phosphoinositide 3 kinase-related family. Inhibiting ATR kinase leads to increased accumulation of single-strand DNA breaks, particularly meaningful for tumor cells which rely on DNA damage repair (DDR). Preclinical studies have demonstrated that ATR inhibitor monotherapy or combination with other drugs (including DDR agents) could be promising therapeutic strategies for solid tumors (including gastric, esophageal, squamous cell carcinoma) and hematologic malignancies (chronic lymphocytic leukemia (CLL), diffuse large B-cell lymphoma [DLBCL] and multiple myeloma [MM]).

According to a preclinical poster presented at AACR (Free AACR Whitepaper) 2022, ATG-018 has demonstrated potent in vitro and in vivo monotherapy efficacy in solid tumor/hematologic cancer models with certain homologous recombination deficiencies. These data were supported by a series of genetic alterations that correlated with ATG-018 sensitivity and could be potential predictive biomarkers. Taken together, these data suggest that ATG-018 could be a promising therapeutic agent for patients with such homologous recombination deficiencies/genetic alterations.

ATG-018 is a development stage product candidate and is not approved by any regulatory agency. Antengene has global rights to ATG-018.

Cellectar Biosciences Announces Positive DMC Review of Pivotal Trial of
Iopofosine in Waldenstrom’s Macroglobulinemia

On April 26, 2022 Cellectar Biosciences, Inc. (NASDAQ: CLRB), a late-stage clinical biopharmaceutical company focused on the discovery, development and commercialization of targeted drugs for the treatment of cancer, reported an independent Data Monitoring Committee (DMC) has completed its planned futility/efficacy assessment of the company’s pivotal Phase 2b study of iopofosine in Waldenstrom’s macroglobulinemia (WM) and unanimously recommended continuation of the trial as planned (Press release, Cellectar Biosciences, APR 26, 2022, View Source [SID1234612961]).

"We remain highly encouraged with the consistent performance of iopofosine I-131 in this difficult-to-treat refractory patient population," said James Caruso, president and chief executive officer of Cellectar. "We have alignment with the FDA on a 20% major response rate hurdle as the primary endpoint of our pivotal study. In a poster presented at ASCO (Free ASCO Whitepaper) 2021, we showed an 83.3% major response rate with one complete response in six WM patients, which served as the basis for our pursuing this indication."

The pivotal trial is a global, non-comparator, single-arm, open-label expansion cohort of the currently ongoing Phase 2 CLOVER-1 study of CLR 131. The study will enroll 50 WM patients. Patients in the trial will receive up to four doses of iopofosine over two cycles (cycle one on days 1, 15, and cycle two on days 57 and 71). The primary endpoint of the trial is major response rate as defined as a partial response (a minimum of a 50% reduction in the biological marker IgM) or better in patients that receive a minimum total body dose of 60 mCi with secondary endpoints of treatment free survival, duration of response and progression free survival.

The DMC is an independent committee of clinical research experts who review data in ongoing clinical trials. The DMC assessment was based on a pre-specified futility analysis within the first 10 patients as defined in the study protocol.

About Waldenstrom’s macroglobulinemia
Waldenstrom’s macroglobulinemia (WM) is a rare and incurable disease defined by specific genotypic subtypes that defines patient responses and long-term outcomes. The U.S. annual incidence is 3,000 (anticipated annual growth rate of approximately 30% through 2025) with a current U.S. prevalence of approximately 45,000 patients. The U.S. represents approximately 43% of the global market. WM is a lymphoma, or cancer of the lymphatic system. The disease occurs in a type of white blood cell called a B-lymphocyte or B-cell, which normally matures into a plasma cell whose job is to manufacture immunoglobulins (antibodies) to help the body fight infection. In WM, there is a malignant change to the B-cell in the late stages of maturing, and it continues to proliferate into a clone of identical cells, primarily in the bone marrow but also in the lymph nodes and other tissues and organs of the lymphatic system. These clonal cells over-produce an antibody of a specific class called IgM.

WM cells have characteristics of both cancerous B-lymphocytes (NHL) and plasma cells (multiple myeloma), and they are called lymphoplasmacytic cells. For that reason, WM is classified as a type of non-Hodgkin’s lymphoma called lymphoplasmacytic lymphoma (LPL). About 95% of LPL cases are WM; the remaining 5% do not secrete IgM and consequently are not classified as WM.

There is no standard treatment for WM. Several drugs have demonstrated activity either alone or in combinations, but only a single drug has received regulatory approval. Treatment is mainly focused on the control of symptoms and the prevention of organ damage. Front-line treatments for WM include rituximab alone or in combination with other agents. In the salvage therapy (second line or later) setting, ibrutinib, combinations of proteosome inhibitors and immunomodulatory drugs and stem cell transplantation are considered. Ibrutinib is the only drug to receive regulatory approval (2015) as a salvage therapy; in late 2019, it was approved for front-line treatment in combination with rituximab. Factors such as long-term cytopenias, age, hyper viscosity, the need for quick disease control, lymphadenopathy, co-morbidities, and IgM-related end-organ damage are key considerations in the choice of treatment.

Isleworth Healthcare Acquisition Corp. and Cytovia Therapeutics Announce Agreement for Business Combination to Create Publicly Listed Company Focused on Empowering Natural Killer Cell Therapeutics to Fight Cancer

The combined company will continue Cytovia’s operations and remain focused on developing and manufacturing complementary NK cell and NK engager antibody platforms.

The combined company will be led by Dr. Daniel Teper, the Co-Founder, Chairman, and Chief Executive Officer of Cytovia.

"We are grateful for the strong support from new and existing investors and the team of seasoned entrepreneurs at Isleworth. We expect this transaction to accelerate the execution of Cytovia’s vision to advance NK therapeutics towards a cure for cancer" said Dr. Teper. "We are encouraged by our preclinical data recently presented at AACR (Free AACR Whitepaper), which supports advancing development of our iPSC-derived NK cells (iNK) and Flex-NK cell engagers for the treatment of Hepatocellular Carcinoma."

Bob Whitehead, Isleworth’s CEO, said: "Isleworth evaluated multiple life science companies and was most impressed by the talent and technology assembled by Cytovia. We believe Cytovia is one of the most advanced, innovative cell therapy companies involved with the development of new cancer treatments. Cell therapies in oncology have already brought hope to millions. Cytovia’s approaches could conceivably make similar approaches more conveniently ‘off-the-shelf’ and affordable."

Cytovia’s Therapeutic Approach

Cytovia aims to accelerate patient access to transformational cell therapies and immunotherapies, addressing several of the most challenging unmet medical needs in oncology.

The company focuses on harnessing the innate immune system by developing complementary and disruptive NK-cell and NK-engager antibody platforms. Specifically, Cytovia is developing three types of iNK cells: unedited iNK cells, TALEN gene-edited iNK cells with improved function and persistence, and TALEN gene-edited iNK cells with chimeric antigen receptors (CAR-iNKs) to improve tumor-specific targeting. The second complementary cornerstone technology is a quadrivalent multispecific antibody platform designed to engage NK cells by targeting the NKp46 activating receptor using a proprietary Flex-NK technology.

These two technology platforms are being used to develop treatments for patients with Hepatocellular Carcinoma (HCC) and solid tumors. Clinical studies are expected to initiate by the end of 2022.

Headquartered in Aventura, FL, Cytovia operates R&D laboratories in Natick, MA and a cGMP cell manufacturing facility in Puerto Rico and has scientific partnerships with Cellectis, CytoImmune Therapeutics, the Hebrew University of Jerusalem, INSERM, the New York Stem Cell Foundation, the National Cancer Institute, and the University of California San Francisco (UCSF). Cytovia Therapeutics has recently formed CytoLynx Therapeutics, a strategic partnership focused on research and development, manufacturing, and commercialization activities in Greater China and beyond.

Cytovia Pipeline

Cytovia is the first immune-oncology company with the capabilities to combine gene edited iPSC-derived NK Cell and Flex-NK cell engager antibody platforms to develop the next generation of immunotherapies for both hematological and solid tumors.

Cytovia’s portfolio includes targets and indications with a balanced risk profile.

GPC3 is a promising novel target for solid tumors, particularly hepatocellular carcinoma, where the unmet medical need is most significant. Cytovia’s lead program aims to develop first-in-class HCC therapies targeting GPC3. The initial four product candidates will be evaluated as monotherapies and as combination therapies. CYT-303, Cytovia’s GPC3 Flex-NK engager, is a tri-specific antibody that binds to HCC tumor cells through GPC3 and to NK cells through NKp46 and CD16a. For patients with either an impaired number or function of NK cells, Cytovia will evaluate the addition of iNK cells, CYT-100, to possibly unlock the full potential of this treatment strategy. Cytovia is also developing CYT-150, gene-edited iNK cells, to improve tumor infiltration and cell persistence, that may also be combined with CYT-303. In addition, CYT-503, a GPC3-targeting CAR-iNK cell therapeutic, is designed to improve specificity for tumor targeting. Cytovia expects to file INDs for CYT-303 and CYT-100, followed by INDs for CYT-150 and CYT-503.

CD38 is a well-established clinical and commercial target for Multiple Myeloma. Cytovia is developing CYT-338 and CYT-538 which are, respectively, CD38-targeting Flex-NK cell engagers and CAR-iNK cells for the treatment of Multiple Myeloma in patients that have failed CD38 antibody therapies and agents targeting B-cell maturation antigen (BCMA).

Cytovia is also developing an intracranial EGFR CAR iNK candidate to target both wtEGFR and EGFR vIII to address a significant medical need in the management of the currently untreatable Glioblastoma multiforme.

Cytovia has established collaborations with academic institutions and industry partners including Cellectis for TALEN gene-editing. TALEN gene-editing is a technology pioneered and controlled by Cellectis, a clinical-stage biotechnology company using its gene-editing platform to develop life-saving cell and gene therapies. The TALEN gene-edited patents controlled by Cellectis in the field of iNK and CAR-iNK are licensed from Cellectis by Cytovia and Cytovia holds global development and commercial rights to these patents.

Planned Milestones and Use of Proceeds

Proceeds from private placements (the "PIPE"), funds in Isleworth’s trust account (net of redemptions), and proceeds from other prospective financings, in the aggregate amount of up to one hundred million dollars, would provide Cytovia with capital for up to 2 years to further develop its gene-edited iNK and Flex-NK cell engager technologies. Cytovia plans to focus on multiple milestones, including:

Filing the first two INDs for Flex-NK CYT-303 and iNK CYT-100
Initiating Phase I/II clinical trials to evaluate CYT-303 and CYT-100, alone and in combination, for the treatment of HCC
Obtaining and presenting initial clinical data for CYT-303 and CYT-100 in HCC
Filing INDs for CYT-150 and CYT-503 and initiating Phase I/II clinical trials
Continuing to enhance iNK & Flex-NK technologies and advance the pipeline with multiple therapeutic candidates
Summary of Transaction

The transaction would value the combined company at a pro forma equity value of $602 million, assuming a $10 per share price, no Isleworth stockholder redemptions and no additional financing obtained prior to the closing of the transaction. As a result of the transaction, the combined company would have up to $227 million in gross proceeds from a combination of approximately $207 million in cash held in Isleworth’s trust account (assuming no Isleworth stockholders exercise their redemption rights at closing) and $20 million from PIPE financing of new investors, and without considering the proceeds of any additional prospective financing.

All existing Cytovia equity holders will roll the entirety of their equity holdings into the combined company and are expected to hold approximately half of the issued and outstanding equity of the combined company immediately following the closing (assuming no Isleworth shareholders exercise their redemption rights at closing).

The transaction, which has been approved by each of Isleworth’s and Cytovia’s Boards of Directors, is expected to be completed in the third quarter of 2022, subject to approval by Isleworth’s and Cytovia’s shareholders and satisfaction, or the waiver of, customary closing conditions identified in the business combination agreement.

Isleworth and Cytovia have agreed in the business combination agreement to take all necessary action to cause the board of directors of the combined company immediately following the closing to consist of seven directors, of whom two individuals will be designated by Isleworth and five individuals will be designated by Cytovia. Each designee will meet the director qualification and eligibility criteria of the Nominating and Corporate Governance committee of the board of directors of Isleworth, and a number of Cytovia designees will qualify as independent directors as determined by the board of directors of Isleworth such that a majority of the directors as of immediately following the closing will qualify as independent directors.

I-Bankers Securities, Inc. is serving as capital markets advisor and placement agent to Isleworth. Truist Securities is acting as financial advisor, placement agent and capital markets advisor to Cytovia. BTIG LLC is acting as capital markets advisor to Cytovia.

Cooley LLP is serving as legal advisor to Cytovia. ArentFox Schiff LLP is serving as legal advisor to Isleworth. Goodwin Procter is serving as legal advisor to Truist Securities in its role as placement agent.
