Iomab-B is currently being investigated in the ongoing pivotal Phase 3 SIERRA trial, which is over 75% enrolled, for targeted conditioning prior to potentially curative bone marrow transplant (BMT) for patients with relapsed or refractory Acute Myeloid Leukemia ("R/R AML"). In addition, Actinium is utilizing apamistamab with lower doses of iodine-131, known as Iomab-ACT, for targeted conditioning prior to gene therapy and adoptive cell therapy ("ACT"), namely CAR-T, including in its recently announced collaboration with Memorial Sloan Kettering Cancer Center that is supported by NIH STTR Fast Track grant funding.

"The continued protection of our lead asset Iomab-B, our Iomab-ACT program and apamistamab by a strong patent position is an important component of our development efforts, particularly as we approach the conclusion of our pivotal Phase 3 SIERRA trial for BMT conditioning in R/R AML The growth of BMT, ACT and Gene Therapy has highlighted the importance of conditioning and the need to move beyond non-targeted chemotherapy to increase the number of patients that could benefit from these potentially curative therapies. CD45 is an ideal target for conditioning applications given its unique expression on blood cancer cells and blood forming stem and immune cells and with no expression outside the hematopoietic or blood system," said Dr. Dale Ludwig, Actinium’s Chief Scientific Officer. "Apamistamab is well characterized and its use in conditioning is supported by extensive clinical data across multiple clinical trials and indications. Our robust data shows that apamistamab has a favorable biodistribution profile that, together with our ARC technology, has significant advantages over other approaches such antibody drug conjugates that require payload internalization, making them impractical for targeting CD45. Further, our ARC approach allows us to use varying intensities of targeted radiation to achieve our desired conditioning outcome. With these important patents in place, and continued expansion of our patent portfolio in the US, EU and other select countries, we look forward to continuing to build out our targeted conditioning strategic business unit."

About Iomab-B

Iomab-B is Actinium’s lead product candidate that is currently being studied in a 150-patient, multicenter pivotal Phase 3 clinical trial in patients with relapsed or refractory acute myeloid leukemia who are age 55 and above. Upon approval, Iomab-B is intended to prepare and condition patients for a bone marrow transplant, also referred to as a hematopoietic stem cell transplant, which is often considered the only potential cure for patients with certain blood-borne cancers and blood disorders. Iomab-B targets cells that express CD45, a pan-leukocytic antigen widely expressed on white blood cells with the monoclonal antibody, apamistamab (formerly BC8), labeled with the radioisotope, iodine-131. By carrying iodine-131 directly to the bone marrow in a targeted manner, Actinium believes Iomab-B will avoid the side effects of radiation on most healthy tissues while effectively killing the patient’s cancer and marrow cells. In a Phase 1/2 clinical study in 68 patients with advanced AML or high-risk myelodysplastic syndrome (MDS) age 50 and older, Iomab-B produced enabled 100% of patients to proceed to transplant with all patients achieving transplant engraftment by day 28. Iomab-B was developed at the Fred Hutchinson Cancer Research Center where it has been studied in almost 300 patients in a number of blood cancer indications, including acute myeloid leukemia, chronic myeloid leukemia, acute lymphoblastic leukemia, chronic lymphocytic leukemia, Hodgkin’s disease, Non-Hodgkin lymphomas and multiple myeloma. Actinium obtained the worldwide, exclusive rights to apamistamab (BC8) and Iomab-B from the Fred Hutchinson Cancer Research Center. Iomab-B has been granted Orphan Drug Designation for relapsed or refractory AML in patients 55 and above by the U.S. Food and Drug Administration and the European Medicines Agency.

Theralase Granted FDA Fast Track Designation for NMIBC Phase II Clinical Study

On November 23, 2020 Theralase Technologies Inc. ("Theralase" or the "Company") (TSXV: TLT) (OTCQB: TLTFF), a clinical stage pharmaceutical company focused on the research and development of light activated Photo Dynamic Compounds ("PDC") and their associated drug formulations used to safely and effectively destroy various cancers, bacteria and viruses reported that the U.S. Food and Drug Administration ("FDA") has granted Theralase Fast Track Designation ("FTD") for its Phase II Bacillus Calmete Guérin ("BCG")–Unresponsive Non-Muscle Invasive Bladder Cancer ("NMIBC") Carcinoma In Situ ("CIS") clinical study ("Study II") (Press release, Theralase, NOV 23, 2020, View Source [SID1234571584]).

As a Fast Track designee, Theralase will have access to early and frequent communications with the FDA to discuss Theralase’s development plans and ensure timely collection of the appropriate clinical data to support the approval process. The accelerated communication with the FDA potentially allows, TLD-1433, in combination with the TLC-3200 medical laser system ("TLC-3200"), to be the first intravesical patient-specific Ruthenium-based PDC for the treatment of patients with BCG-Unresponsive NMIBC CIS, with or without papillary Ta or T1 tumours. FTD can lead to an Accelerated Approval and Priority Review, if certain criteria are met, which the FDA has previously defined to the Company to represent approximately 20 to 25 patients enrolled and treated, who demonstrate significant safety and efficacy clinical outcomes.

Michael Jewett MD, FRCSC, FACS, Inaugural Farquharson Clinical Research Chair in Oncology, Departments of Surgery (Urology) and Surgical Oncology, Princess Margaret Cancer Centre, University Health Network ("UHN"), stated "By awarding Fast Track Designation to the photosensitizer drug TLD-1433 activated by the laser TLC-3200, currently being assessed in a Phase II clinical study for the treatment of NMIBC, the FDA has recognized Theralase’s potential to meaningfully improve patient outcomes for this life-threatening disease. This is a significant accomplishment for the Company. This latest milestone complements the clinical development strategy to provide urologists, uro-oncologists and patients with the tools to combat BCG-Unresponsive NMIBC, safely and effectively."

Shawn Shirazi PhD, Chief Executive Officer, Theralase, stated, "FDA’s FTD for our lead drug candidate, TLD-1433, activated by the TLC-3200, is another important milestone for Theralase, as it can potentially speed the development of this drug-device combination for NMIBC patients. The TLD-1433 – TLC-3200 technology represents a paradigm shift in medical technology and an advanced approach to treat NMIBC. We are excited by the progress the Company has delivered in Study II, as we continue to enroll and successfully treat patients. The Company continues to work towards launching new clinical study sites in Canada and the US with a mandate to enroll and treat all patients for their first Study II treatment in 2021".

About Fast Track Designation

FTD is an FDA process designed to facilitate the development, and expedite the review of, medicines to treat serious conditions and fill unmet medical needs. Filling an unmet need is defined as providing a therapy where none exists or providing a therapy that may be potentially better than available therapies. The FDA created this process to help deliver important new drugs to patients earlier, and it covers a broad range of serious illnesses.

About Study II

Study II utilizes the Therapeutic Dose (0.70 mg/cm2) of TLD-1433, activated by the TLC-3200, and is focused on the enrollment and treatment of approximately 100 BCG-Unresponsive NMIBC CIS patients in up to 20 clinical study sites located in Canada and the US.

Study II has a:

Primary endpoint of efficacy (defined by Complete Response ("CR") at any point in time
Secondary endpoint of duration of CR at 360 days post-initial CR (approximately 450 days post initial Study treatment, assuming CR is achieved at the 90 day assessment)
Tertiary endpoint of safety measured by incidence and severity of Adverse Events ("AEs") grade 4 or higher that do not resolve within 450 days post-initial treatment
The FDA, in its 2018 guidance to industry, stated that, "For single-arm trials of patients with BCG-Unresponsive disease, CR is defined as at least one of the following:

Negative cystoscopy and negative (including atypical) urine cytology
Positive cystoscopy with biopsy-proven benign or low-grade NMIBC and negative cytology
For intravesical therapies without systemic toxicity, negative cystoscopy with malignant urine cytology, if cancer is found in the upper tract or prostatic urethra and random bladder biopsies are negative.
The FDA further states that, "Intravesical instillation does not deliver the investigational drug to the upper tract or prostatic urethra; therefore, the development of disease in these areas cannot be attributed to a lack of activity of the investigational drug. Thus, sponsors can consider patients with new malignant lesions of the upper tract or prostatic urethra, who have received intravesical therapy to have achieved a CR in the primary analysis; however, sponsors should record these lesions and conduct sensitivity analyses in which these patients are not considered to have achieved a CR."1
