MTTI Reports on 225Ac-EBTATE and 177Lu-EBTATE Radiopharmaceuticals at 2024 Society of Nuclear Medicine and Molecular Imaging Annual Meeting

FOR IMMEDIATE RELEASE

West Chester, PA, May 21, 2024, 6:01 am Eastern Standard Time (Business Wire)–Molecular Targeting Technologies, Inc. (MTTI), will update findings on both 177Lu-EBTATE clinical and 225Ac-EBTATE preclinical work during the 2024 SNMMI meeting in Toronto June 8-11 (exhibition booth #1819).

177Lu-EBTATE® an EvaThera drug, is the first patented long-acting peptide targeted radiotherapeutic drugs. It selectively targets and binds to somatostatin receptor 2 on neuroendocrine and other tumors, which are then killed by the radionuclide payload. Evans blue in EBTATE binds to serum albumin, extending in vivo circulatory half-life and tumor residence time, enabling effective use of significantly lower radiopharmaceutical activity and fewer dosing cycles vs. the current standard of care (SOC). These benefits are also evident in recent studies of the 225Ac-EBTATE homolog.

Professor Zhaohui Zhu, MD, Peking Union Medical College Hospital, reflected “In our 3-year follow up on 30 patients* with metastatic neuroendocrine tumors (mNETs), 177Lu-EBTATE demonstrated good safety, with no nephro- or hepatoxicity and 86% disease control rate using 60% less radioactivity than 177Lu-DOTATATE. We observed low incidence of grade 3 hematoxicity (3.4% vs 15% of reported SOC) and no long-term nephrotoxicity of any grade.”

The study “Long acting 225Ac-EBTATE is highly efficacious against somatostatin receptor-2-positive small-cell lung cancer (SCLC)**” has been accepted for presentation at 2024 SNMMI. Professor Humphrey Fonge of the University of Saskatchewan commented, “225Ac-EBTATE (2x 30 kBq administered 10 days apart) was effective against SCLC with 80% complete remissions and 100% survival. Treatment yielded a 2-fold greater tumor growth inhibition when compared with 225Ac-DOTATATE, at 60% less administered radioactivity. Toxicity, as measured by body weight, blood counts, and chemistry showed that 225Ac-EBTATE was well tolerated at a highly effective dose. 225Ac-EBTATE shows great promise against SCLC.” Chris Pak, President & CEO of MTTI commented: “We are pleased to learn that 177Lu-EBTATE exhibited no safety concerns and was effective at a lower dose than SOC in mNET patients. We are also encouraged that 225Ac-EBTATE out-performed 225Ac-DOTATATE, providing a 2-fold greater tumor growth inhibition in preclinical findings using a much lower dose of radioactivity.  We look forward to advancing our clinical trials with these radiotherapeutic drugs in small-cell lung and other cancers.”

Molecular Targeting Technologies, Inc. and Molecular Theranostics Center of Singapore receiveHSA approval for Clinical Trial Authorization for EBTATE® in Nasopharyngeal Cancer

FOR IMMEDIATE RELEASE

West Chester, PA, and Singapore, August 2, 2023 — Molecular Targeting Technologies, Inc. (MTTI), and its wholly owned subsidiary, Molecular Theranostic Center of Singapore (MTCS), announced the approval of a Clinical Trial Authorization (CTA) application by the Health Sciences Authority (HSA) of Singapore. The CTA enables a Phase IB/II, open-label study of the safety and efficacy of a 3-dose regimen of 177Lu-DOTA-EB-TATE (EBTATE) in patients with nasopharyngeal cancer (NPC) to be conducted at the National University Cancer Institute Singapore (NCIS) and the National University of Singapore (NUS).

Somatostatin receptor 2 (SSTR2) is found in 81% of primary, recurrent, and metastatic NPC patients. EBTATE, the first patented and only long-acting peptide receptor radionuclide therapy (PRRT) targeting SSTR2 receptors, binds reversibly to serum albumin, resulting in prolonged circulation half-life, increased tumor uptake and retention, and improved therapeutic outcome by delivering an 8-fold greater dose to the tumor compared to 177Lu-Dotatate. A recent three-year clinical trial follow-up* showed EBTATE was effective at controlling tumor and well tolerated without serious adverse events or nephrotoxicity. 

NPC has a high prevalence with 133,354 new cases and 80,008 deaths in 2020**.  While treatment options include surgery, chemotherapy and radiation therapy, there are no approved molecularly targeted therapies for NPC.

Professor Goh Boon Cher, MD, Deputy Director of NICS and NUS, stated “We are pleased to be collaborating with MTTI/MTCS to evaluate this novel treatment for SSTR2 expressing NPC. The study which will be conducted at our hospital will bring new hope for nasopharyngeal cancer patients.”

Dr. Chris Pak, President & CEO of MTTI and Chairman of MTCS, remarked: “The Evans Blue (EB)-albumin binding motif of EBTATE prolongs its circulation half-life and enhances tumor targeting.  In preclinical and early clinical studies, EBTATE provided several advantages such as 8-fold uptake in tumor and lower administered radioactive dose versus first generation 177Lu-Dotatate in many cancers.  We hope this groundbreaking treatment will be beneficial for nasopharyngeal cancer patients.”

MTTI Highlights Promising One-Year Follow-Up on Ebtate Treatment of Neuroendocrine Cancer Patients Without Amino Acid Infusion

FOR IMMEDIATE RELEASE

West Chester, PA June 21, 2023 — Molecular Targeting Technologies, Inc. (MTTI) announced promising results from a 1-year follow-up on EBTATE (2 cycles, 3.7 GBq/cycle) treatment of gastroenteropancreatic neuroendocrine tumors (GEP-NETs) without amino acid pretreatment. EBTATE’s safety, biodistribution, and dosimetry in a crossover randomized protocol in patients (N=10) with and without amino acids were published in Clinical Nuclear Medicine.1

The kidney is sensitive to radiation. Peptide receptor radionuclide therapy (PRRT) dosing is constrained by potential kidney toxicity. A 4-hour long amino acid cocktail infusion reduces renal absorbed radiation dose, with significant side effects like nausea, vomiting and hyperkalemia. The Evans blue moiety in EBTATE binds to serum albumin, extending in vivo circulatory half-life and residence time, reducing renal uptake and hence making amino acid infusion unnecessary.

Professor Zhaohui Zhu, MD, principal investigator, commented, “Our results showed that administration of EBTATE without amino acid infusion had acceptable kidney radiation absorbed dose and residence time. One month after EBTATE, there were no significant changes in creatinine, blood urea nitrogen (BUN), and glomerular filtration rate (GFR). None of the patients had nephrotoxicity of any grade. Furthermore, a recent one-year follow-up showed creatine and BUN of all patients stayed within normal limits. EBTATE administration appears to be safe without amino acid infusion.”

Chris Pak, President & CEO of MTTI commented, “Amino acid infusion impacts quality of life, access to care, patient compliance to treatment and overall treatment costs. The benefits of EBTATE treatment without amino acids are clear. We expect EBTATE trials in small cell lung cancer, NET, nasopharyngeal cancers to show the same benefit.”

MTTI Announces Favorable Three-Year Follow-Up for EBTATE in Neuroendocrine Tumors

FOR IMMEDIATE RELEASE

West Chester, PA June 19, 2023 — Molecular Targeting Technologies, Inc. (MTTI) announced favorable findings of a 3-year follow- up of EBTATE (3 cycles, 3.7 GBq/cycle) against metastatic gastroenteropancreatic neuroendocrine tumors (GEP-NETs). Results from this study were published in Theranostics.1

EBTATE is the first patented long-acting peptide targeting radiotherapeutic drug. It selectively targets somatostatin receptor 2 (SSTR2) on GEP-NETs, which are then killed by the radionuclide payload. The Evans blue moiety in EBTATE binds to serum albumin, extending in vivo circulatory half-life and residence time, enabling effective but lower radioactivity and fewer dosing cycles vs. the current standard of care (SOC). These findings confirm the safety and efficacy of the previous EBTATE results in 62 NET patients.

Professor Zhaohui Zhu, MD, principal investigator, said “Low occurrence of short and long-term toxicity proved EBTATE is safe (N=29). None of the patients developed leukemia or bone marrow disease during the 3-year follow-up. We observed low incidence of grade 3 hematoxicity (3.4% vs 15% of reported SOC) and no nephrotoxicity of any grade in long-term safety evaluation. Using EBTATE at lower radioactivity (37%) was as effective as SOC in disease control and achieved higher objective response based on RECIST criteria.”

Chris Pak, President & CEO of MTTI commented: “It is rewarding to see how EBTATE helped these patients. We look forward to the same benefits from EBTATE trials in small cell lung cancer, nasopharyngeal cancers, Hürthle cell thyroid and others.”

MTTI obtains FDA allowance of Investigational New Drug (IND) for Hürthle Cell Thyroid Cancer

FOR IMMEDIATE RELEASE

West Chester, PA December 8, 2022, 6:01 am Eastern Standard Time (Business Wire)
— Molecular Targeting Technologies, Inc. (MTTI), a clinical stage radiopharmaceutical
therapy company focused on therapies for rare diseases, announced today the allowance of an Investigational New Drug (IND) application by the U.S. Food and Drug Administration (FDA). It is now waiting for Institutional Review Board (IRB) approval. Once approved by IRB, it will enable a Phase I/II clinical study of the Safety, Dosimetry and Efficacy of EBTATE in adult patients with metastatic, radioactive iodine nonresponsive Hürthle cell thyroid cancer.”

EBTATE is a new generation of peptide receptor radiotherapeutic drug that has demonstrated potential clinical superiority over standard of care. It selectively binds to somatostatin receptor 2 (SSTR2) on neuroendocrine and other tumors, which are then killed by the radionuclide. EvaThera platform products were designed to bind to serum albumin, due to the Evans blue moiety, extending in vivo residence time, enabling lower, less frequent dosing of the radiopharmaceutical and reducing risk of renal injury vs. the current standard of care.

Dr. Joanna Klubo-Gwiezdzinska, MD, Ph.D, MHSc, acting section chief of Thyroid Tumors and Functional Thyroid Disorders in the National Institute of Diabetes and Digestive and Kidney Diseases, part of the National Institutes of Health (NIH) and study author commented: “Hürthle cell thyroid cancer, which currently lacks effective treatment options, is characterized by a particularly high expression of SSTR2*. With this phase I/II clinical trial, we hope to implement individualized dosimetry-based dosing for each patient with Hürthle cell thyroid cancer that spread outside of the thyroid gland and analyze how much of an active agent is being accumulated in the tumor tissue to establish a threshold associated with the best efficacy and safety.”

Dr. Chris Pak, President & CEO of MTTI commented: “The clearance of our IND is an important milestone for MTTI. Having solidified our clinical trial preparedness and manufacturing readiness, we are well-positioned to advance EBTATE to target Hürthle cell thyroid cancer.”

SNMMI 2022 Accepted Oral Abstract: EBTATE safety with and without Amino Acid Infusion

Evaluation of Safety, Biodistribution and Dosimetry of a long-Acting Radiolabeled Somatostatin Analogue 177Lu-DOTA-EB-TATE with and without Amino Acid Infusion

Synopsis:

Evaluation of Safety, Biodistribution and Dosimetry of a long-Acting Radiolabeled Somatostatin Analogue 177Lu-DOTA-EB-TATE with and without Amino Acid Infusion.

Purpose/Background:

Kidneys are considered one of the dose-limiting organs in peptide receptor radionuclide therapy (PRRT), especially when using 90Y-PRRT. Amino acid was infused to reduce renal absorbed dose by inhibiting the proximal tubular reabsorption of the radiopeptide. However, due to the lower penetration range of β- particles emitted by 177Lu, the renal dysfunction caused by 177Lu-PRRT is rare. An Evans blue-modified 177Lu-labeled octreotate (177Lu-DOTA-EB-TATE) have an extended circulation in the blood, making little protective effect of amino acids on the kidneys. The aim of this prospective study was to evaluate the safety, biodistribution and dosimetry of 177Lu-DOTA-EB-TATE with and without amino acid infusion. .Kidneys are considered one of the dose-limiting organs in peptide receptor radionuclide therapy (PRRT), especially when using 90Y-PRRT.

The aim of this prospective study was to evaluate the safety, biodistribution and dosimetry of 177Lu-DOTA-EB-TATE with and without amino acid infusion.

Methods:

A total of 10 advanced metastatic neuroendocrine tumors were recruited and were randomly divided into 2 groups: group A (n=5, Male/Female=3/2, mean age 43±7 years old) received a single dose 3.9±0.2 GBq (105.6±4.6 mCi) of 177Lu-DOTA-EB-TATE without amino acid infusion; group B (n=5, Male/Female=3/2, mean age 56±8 years old) received a single dose 3.3±0.1 GBq (88.5±2.6 mCi) of 177Lu-DOTA-EB-TATE with amino acid infusion (25g lysine+25g arginine diluted in 2L of normal saline infused over 4 h, starting 30–60 min before PRRT). All patients underwent serial whole body planar at 1, 24, 96, 168h after administration and underwent single-photon emission computed tomography (SPECT) at 24h after administration. Abdominal CT was performed 2 days before administration for SPECT/CT image fusion. Hematological parameters, liver and renal function (creatinine and BUN) at baseline, 1 week and 4 weeks after administration were tested. 99mTc-DTPA dynamic renal imaging used for determination of the GFR was performed at baseline and 8 weeks after administration. Treatment-related adverse events were graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE), version 5.0. Dosimetric calculations were done using the HERMES software (HERMES Medical Solutions, Stockholm, Sweden).

Results:

Administration of 177Lu-DOTA-EB-TATE with/without amino acid was well tolerated, with no CTC-3/4 hematotoxicity, hepatotoxicity or nephrotoxicity being recorded. In group A, no significant difference was observed in creatinine (t=0.485, P=0.653), BUN (t=0.585, P=0.590) or GFR (t=0.741, P=0.512). In group B, no significant difference was observed in creatinine, BUN or GFR as well. The total body effective dose has no significant difference between group A and B (0.222±0.100 vs 0.105±0.014 mSv/MBq, P=0.279) as well as kidney effective dose (2.013±0.808 vs 0.622±0.117 mSv/MBq, P=0.127). The residence time of the kidneys was 6.6±2.5h in group A and 2.1±0.4h in group B (P=0.113).

Conclusion:

177Lu-DOTA-EB-TATE without amino acid infusion is safe, with no kidney dysfunction being occurred. It could not only greatly simplify the PRRT procedure, but also avoid amino acid-related side effects.

MTTI features EBTATE advances at the 2022 SNMMI meeting in Vancouver, BC

West Chester, PA, June 9, 2022 — Molecular Targeting Technologies, Inc. (MTTI), a clinical stage oncology company, will highlight advances on its EvaTheraTM radiotheranostics platform at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) meeting in Vancouver, BC, on June 11-15, 2022 (Exhibit booth #1715).  The EvaThera platform includes  EBTATETM (177Lu-DOTA-EB-TATE) for Neuroendocrine Neoplasms (NENs), Hürthle cell thyroid and nasopharyngeal cancers and EBRGDTM (177Lu-DOTA-EB-RGD)  for glioblastoma multiforme and non-small cell lung cancer.

A video featuring the EBTATE story (see link below) will be released at the meeting. 

In addition, two abstracts highlighting MTTI’s EBTATE & our PET imaging agent,18F-glucarate, were selected for oral and poster presentations:

  • Evaluation of Safety, Biodistribution and Dosimetry of a long-Acting Radiolabeled Somatostatin Analogue 177Lu-DOTA-EB-TATE with and without Amino Acid Infusion by Qingxing Liu, Yuanyuan Jiang, Koon Pak, Guochang Wang, Jingjing Zhang, Xiaoyuan Chen and Zhaohui Zhu (oral presentation).
    EBTATE treatment without amino acid  infusion, normally used in current treatments to block drug impact on non-target organs, has acceptable, minor effects on the kidneys and does no harm to kidney function.  EBTATE may significantly improve patient comfort vs. current treatments.
  • Assessment of 18F-glucarate as a potential PET tracer for cancer imaging by Junling Li, Huaiyu Zheng, Levi Beverly, Brian Gray, Koon Pak and Chin K. Ng (poster presentation).
    18F-glucarate uptake in both in vitro and in vivo correlated well with the degree of cell death and shows early tumor response to chemotherapy, enabling faster assessment of treatment efficacy.
