Actinium to Highlight Expansion of Targeted Conditioning Portfolio at AACR with Next-Generation Actinium-225-Based CD45 Targeting ARC

On March 11, 2021 Actinium Pharmaceuticals, Inc. (NYSE AMERICAN: ATNM) ("Actinium" or the "Company") reported that preclinical feasibility data supporting an Actinium-225-based CD45-targeted Next-Generation conditioning agent has been accepted for poster presentation at the American Association of Cancer Research (AACR 2021) annual meeting being held virtually April 10th – 15th, 2021 (Press release, Actinium Pharmaceuticals, MAR 11, 2021, View Source [SID1234576525]). The data to be presented includes initial dose escalation, safety, tolerability, and conditioning experiments of an Ac-225-based CD45 ARC or antibody radiation conjugate. Dosimetry results with this Ac-225-based alpha emitting ARC showed selective accumulation in immune cell target organs such as bone marrow, spleen, and liver with the potential for lower exposure to non-target tissues from longer path length beta emitter radioisotopes like Iodine-131 and Lutetium-177. The data to be presented demonstrate that conditioning with this Ac-225-based CD45-targeting agent result in depletion of peripheral immune cells and hematopoietic progenitor cells, thereby enabling engraftment of donor cells. A dose dependent response was observed with low doses depleting white blood without effecting hematopoietic progenitor cells, representing a lymphodepletive dose that is relevant for adoptive cell therapies such as CAR-T, while higher doses eliminated peripheral immune cells and hematopoietic progenitor cells, which is applicable to ex vivo gene therapies and BMT or bone marrow transplant.

This program further augments Actinium’s targeted conditioning portfolio that is led by Iomab-B, an ARC consisting or the radioisotope Iodine-131 and the CD45 targeting antibody apamistamab. In total, apamistamab has been studied in several hundred patients. Iomab-B is currently being studied in the pivotal Phase 3 SIERRA trial for BMT conditioning in patients with active relapsed or refractory acute myeloid leukemia age 55 and above that is expected to complete enrollment in 2021.

Details of the poster presentation at AACR (Free AACR Whitepaper) are as follows:

Dr. Dale Ludwig, Actinium’s Chief Scientific and Technology Officer said, "We are excited to present this data supporting an Ac-225 antibody radiation-conjugate at AACR (Free AACR Whitepaper) and to have the opportunity to develop potentially safer and better targeted chemotherapy-free conditioning agents. Recent cases of secondary malignancies potentially tied to toxic chemotherapy regimens highlight the urgent need for improved conditioning to enable the very promising cell and gene therapy strategies to treat diseases such as Sickle Cell Disease and Beta-Thalassemia. As advances in cell and gene therapies address more disease indications and thus a larger overall patient population, our commitment to developing targeted conditioning agents to improve patient access to the these potentially curative therapies and patient outcomes grows stronger. We look forward to further optimizing this construct to enable advancement into the clinic."

Actinium is developing the only multi-target, multi-indication, clinical-stage pipeline for targeted conditioning and the only ARC based targeted conditioning regimens in development. This Ac-225-CD45 construct to be highlighted at AACR (Free AACR Whitepaper) resulted from Actinium’s AWE or Antibody Warhead Enabling technology platform. AWE encompasses Actinium’s intellectual property of over 140 patents, know-how, and clinical experience including nearly 150 patients treated with alpha emitters like Ac-225 for which Actinium is an industry leader. Specific to Ac-225, Actinium has gold-standard linker technology with a strong stability and safety profile and patents covering composition of matter, formulations, methods of use and methods of manufacturing the radioisotope Actinium-225 in a cyclotron. In addition to fueling Actinium’s R&D efforts, AWE is being utilized in collaborative research partnership with Astellas Pharma, Inc. who is focused on the development of theranostics for solid tumors.

Sandesh Seth, Actinium’s CEO, said "This new program and initial data is yet another example of the potential of Actinium’s AWE platform technology and our team’s ability to create disruptive agents for oncology therapeutics and cell and gene-based therapies. It also exemplifies Actinium’s strong commitment to advancing and increasing access to life-changing and potentially curative therapies. With 2021 expected to be a transformational year for Actinium marked with key clinical milestones including completion of the SIERRA trial it is also exciting to see our R&D efforts delivering tangible results that will position us for continued future success."

Nouscom receives approval to begin Phase 1b trials of NOUS-PEV, a novel personalized cancer immunotherapy

On March 11, 2021 Nouscom, a clinical stage immuno-oncology biotech developing next generation viral-vector based immunotherapies, reported it has received approval from the Spanish National Agency of Medicines and Medical Devices (Agencia Española de Medicamentos y Productos Sanitarios (AEMPS)) to start a Phase 1b trial of its personalized cancer immunotherapy, NOUS-PEV (Press release, NousCom, MAR 11, 2021, View Source [SID1234576548]). NOUS-PEV will be investigated in the study as a potential treatment for patients with either locally advanced 1L melanoma or 1L non-small cell lung cancer (NSCLC).

NOUS-PEV is a personalized vaccine designed for each patient based on selection and prioritization of mutations unique to that patient’s tumor. The strategy is based on Nouscom’s heterologous prime boost platform underpinning its lead off-the-shelf clinical program NOUS-209, composed of a proprietary non-human adenoviral vector (GAd) and Modified Vaccinia Virus (MVA). Each of the two viral vector systems encodes multiple personalized neoantigens selected with a proprietary algorithm (VENUS[1]), which prioritizes up to 60 mutations that represent the most immunogenic neoantigens.

Results from preclinical proof-of-concept studies (published in Nature Communications[2]) demonstrated that a single administration of the GAd vaccine incorporating many neoantigens can eradicate large tumors when combined with checkpoint inhibition such as anti-PD1 or anti-PD-L1 treatment and triples the efficacy of such checkpoint inhibitors. The preclinical results also demonstrated strong and broad CD8+ and CD4+ neoantigen-specific T cell responses following vaccination, which are known to be indicative of a clinical anti-tumor effect.

The new Phase 1b trial will evaluate the safety, feasibility, and preliminary efficacy per RESIST 1.1 criteria of NOUS-PEV in combination with the anti-PD-1 checkpoint inhibitor pembrolizumab in 28 patients with either locally advanced 1L melanoma or 1L NSCLC expressing more than 50% PD-L1. This multicenter trial will be conducted in Spain and other European countries.

Patricia Delaite, M.D., Chief Medical Officer of Nouscom, said: "We have generated exciting pre-clinical data, which demonstrated the ability of NOUS-PEV to present multiple cancer neoantigens to the immune system and promote potent and broad immune responses. The enhanced anti-tumor effects seen by combining NOUS-PEV with checkpoint inhibitors suggests these two approaches are highly synergistic and could potentially overcome tumor resistance to anti-PD1 immunotherapies to address a high unmet medical need. We look forward to starting this trial in the coming weeks and to generating results that we hope will confirm these exciting results in patients."

Dr. Marina Udier, Chief Executive Officer of Nouscom, said: "The regulatory approval of this highly sophisticated study to assess our personalized vaccine NOUS-PEV is another critical milestone for the company. Similar to our lead program, NOUS-209, NOUS-PEV leverages the strength and capacity of our platform based on viral vectors, encoding a large number of neoantigens, with proven robust performance in animal models, which we believe has the potential to translate into real clinical benefits for patients."

Third Fiscal Quarter Financial Results

For the third quarter of fiscal 2021, revenue increased 20.0% to $10.8 million compared to $9.0 million for the third quarter of fiscal 2020. The increase in revenue was due to a continued increase in sales,

Exhibit 99.1
both in number and size of studies, and the expansion of both our platform and product lines. Our contract amounts have increased as we perform more complex studies and end point analysis testing. Total costs and operating expenses for the third quarter of fiscal 2021 were $10.0 million compared to $8.6 million for the third quarter of fiscal 2020, an increase of $1.5 million or 17.1%.

For the third quarter of fiscal 2021, Champions reported income from operations of $763,000, including $232,000 in stock-based compensation and $297,000 in depreciation and amortization expenses, an increase of $330,000 compared to income from operations of $433,000, inclusive of $229,000 in stock-based compensation and $219,000 in depreciation and amortization expenses, in the third quarter of fiscal 2020. Excluding stock-based compensation, depreciation and amortization expenses, Champions reported non-GAAP income from operations of $1.3 million for the third quarter of fiscal 2021 compared to non-GAAP income from operations of $881,000 in the third quarter of fiscal 2020, an increase of $411,000.
Cost of oncology solutions was $4.8 million for the three-months ended January 31, 2021, an increase of $0.5 million, or 12.0% compared to $4.3 million for the three-months ended January 31, 2020. For the three- months ended January 31, 2021, gross margin was 55.2% compared to 52.0% for the three-months ended January 31, 2020. The increase in cost of oncology services for the three-month period was mainly due to an increase in compensation and lab supply expenses. The increase in cost of sales is generally in line with the expected contribution based on the growth in revenue, study volume, and expansion into new services. Gross margin varies based on timing differences between expense and revenue recognition and was boosted by the revenue recognized from outsourced work where costs were partially recognized in prior quarters.
Research and development expense for the three-months ended January 31, 2021 was $1.9 million, an increase of $488,000 or 35.1%, compared to $1.4 million for the three-months ended January 31, 2020, respectively. The increase was due to increased compensation and lab supply expense as we continued to develop new service capabilities and endpoint analysis testing. Additionally, we incurred proteomic sequencing costs as our investment in characterizing our TumorBank continued, adding valuable data to our platform. Sales and marketing expense for the three-months ended January 31, 2021 was $1.5 million, an increase of $185,000, or 14.2%, compared to $1.3 million for the three-months ended January 31, 2020. The increase was primarily due to compensation expense driven by the continued investment in expanding our business development team. General and administrative expense for the three-months ended January 31, 2021 was $1.8 million, an increase of $280,000, or 18.0%, compared to $1.6 million for the three-months ended January 31, 2020, respectively. The increase was primarily due to compensation and IT related expenses.
Net cash used in operating activities was $107,000 for the three-months ended January 31, 2021 compared to net cash provided by operating activities of $280,000 for the same period last year. The decrease in cash flow from operations was primarily due to a significant reduction in our accounts payable balance along with timing differences in other working capital accounts in the ordinary course of business.

The Company ended the quarter in a strong cash position with a $7.4 million cash balance compared to $3.3 million at the end of the same period last year. The Company has no debt.

Year-to-Date Financial Results

For the first nine months of fiscal 2021, revenue increased 30.4% to $30.5 million, as compared to $23.4 million for the first nine months of fiscal 2020. For the first nine months of fiscal 2021, total

Exhibit 99.1
operating expenses increased 27.6% to $29.7 million, as compared to $23.3 million for the first nine months of fiscal 2020. The increase in revenue was due to increased sales, both in number and size of studies, an increase in demand for our services, the growth of the platform, and the expansion of our product line. Our customers are seeking more complex study designs and end point analysis testing, contributing to the larger contract sizes.

For the first nine months of fiscal 2021, Champions reported income from operations of $795,000, which includes $437,000 in stock-based compensation and $881,000 in depreciation and amortization expenses, an increase of $686,000 or 629%, compared to income from operations of $109,000, inclusive of $437,000 in stock-based compensation and $579,000 depreciation, for the first nine months of fiscal 2020. Excluding stock-based compensation and depreciation, Champions reported non-GAAP operating income of $2.1 million for the first nine months of fiscal 2021 compared to non-GAAP operating income of $1.1 million in the same period last year.

Cost of oncology solutions was $15.8 million for the first nine months of fiscal 2021 compared to $12.0 million for the first nine months of fiscal 2020, an increase of $3.9 million or 32.3%. Gross margin was 48.1% for the first nine months of fiscal 2021 compared to 48.8% for the first nine months of fiscal 2020. The increase in cost of oncology services for the nine month period was mainly due to an increase in compensation, lab supply, and outsourced lab service expenses. Gross margin varies based on timing differences between expense and revenue recognition and was driven lower by the increase in costs on growing study volume in advance of revenue recognition. The cost of outsourced lab services amplified this impact.

Research and development expense was $5.1 million for the first nine months of fiscal 2021 an increase of $1.1 million, or 27.0% compared to $4.0 million for the first nine months of fiscal 2020. The increase was due to increased compensation and lab supply expense as we continued to develop new service capabilities and endpoint testing analysis, and incurred sequencing costs as we continued to characterize our TumorBank. Sales and marketing expense for the first nine months of fiscal 2021 was $4.0 million, an increase of $893,000, or 28.3% compared to $3.2 million for the first nine months of fiscal 2020. The increase was primarily due to compensation expense driven by the continued investment in expanding our sales force. General and administrative expense was $4.7 million for the first nine months of fiscal 2021, an increase of $568,000, or 13.8% compared to $4.1 million for the first nine months of fiscal 2020. General and administrative expenses are primarily comprised of compensation, insurance, accounting fees, and depreciation expenses and have increased to support the overall infrastructure growth of the company.

Net cash provided by operations was $299,000 for the first nine months of fiscal 2021 compared to net cash provided by operations of $360,000 in fiscal 2020, a decrease of $61,000 or 16.9%. The decrease in cash from operations was primarily due to timing differences in working capital accounts in the ordinary course of business.

ON 123300 also received Institutional Review Board (IRB) approval at one U.S. clinical trial site
The Phase 1 solid tumor study with ON 123300 in China is ongoing and continues to enroll patients
Raised net proceeds of $35.2 million from two equity offerings; cash and cash equivalents as of February 28, 2021 were approximately $49.5 million
An independent investigator-initiated study with oral rigosertib in combination with a PD-1 inhibitor in advanced KRAS mutated non-small cell lung cancer is ongoing
A Special Meeting of Stockholders to consider changes to the capital structure of the Company will reconvene on April 1, 2021
Management Commentary
"The fourth quarter and recent weeks have been active and productive at Onconova as we continue to advance our lead product ON 123300 into the clinic," said Steven M. Fruchtman, M.D., President and Chief Executive Officer of Onconova. "We submitted an Investigational New Drug application to the FDA for a Phase 1 study in advanced cancers including HR+/HER 2- metastatic breast cancer patients resistant to approved second-generation CDK 4/6 inhibitors. In December 2020, we received clearance from the FDA to begin the study, and have since received IRB approval at our first site. We expect the first patient to be enrolled in the second quarter of this year. Two further sites are in the study set-up process.

"This Phase 1 study will assess the safety, tolerability and pharmacokinetics of ON 123300 administered orally at increasing doses starting at 40 mg daily continuously.

"Our partner in China, HanX Pharmaceuticals, continues enrolling a similar patient population in a Phase 1 dose-escalation study with ON 123300 at two sites. The initial dose cohort has been completed and the second dose cohort is enrolling. We are pleased that ON 123300 appears to be well tolerated so far as no dose-limiting toxicities have been seen to date. The HanX study is dosing patients on a 21-day cycle. Collectively, the U.S. and China Phase 1 studies are expected to provide data regarding the safety profile of ON 123300 and potentially provide preliminary efficacy signals in patients with advanced cancer."

Commenting on ongoing investigator-sponsored studies with oral rigosertib, the company’s RAS pathway inhibitor, Dr. Fruchtman added, "We are currently supporting investigator-initiated studies that are exploring the use of oral rigosertib for cancers driven by mutation of the RAS gene including a Phase 1 study in combination with a PD-1 inhibitor for patients with progressive K-RAS mutated non-small cell lung cancer. This study is open and continues to enroll patients, with the objectives to identify the recommended Phase 2 dose and to characterize the safety profile of the combination treatment. Results are expected in 2021.

"In addition, an investigator-initiated Phase 1b/2 study with oral rigosertib monotherapy in advanced squamous cell carcinoma associated with recessive dystrophic epidermolysis bullosa is open. A preclinical study is also evaluating oral rigosertib in clear cell renal carcinoma. We anticipate additional investigator-initiated studies in RAS-driven cancers in combination with PD-1 inhibitors, including in metastatic melanoma. Other than the cost of supplying oral rigosertib to the investigators, Onconova does not expect to incur significant expense for these studies," Dr. Fruchtman stated.

Full Year Financial Results
Cash and cash equivalents as of December 31, 2020 were $19.0 million, compared with $22.7 million as of December 31, 2019. Subsequent to the end of the quarter, the Company raised net proceeds of $35.2 million from two equity offerings with institutional investors. The Company expects that its cash and cash equivalents as of February 28, 2021 will be sufficient to fund ongoing clinical trials and business operations for more than eighteen months.

Research and development expenses were $16.9 million for 2020, compared with $15.5 million for 2019. The increase was primarily related to higher regulatory consulting fees and manufacturing costs related to clinical supply for ON 123300, partially offset by lower expenses for the oral rigosertib combination program and the Phase 3 INSPIRE study in the 2020 period.

General and administrative expenses were $8.3 million for 2020, consistent with 2019. Lower personnel and stock compensation expenses in 2020 due to personnel reductions in the 2019 period were offset by higher pre-commercialization, insurance, and corporate legal and stockholder meeting expenses in the 2020 period.

Net loss for 2020 was $25.2 million, or $0.14 per share on 174.0 million weighted average shares outstanding, compared with a loss of $21.5 million, or $1.49 per share for 2019 on 14.4 million weighted average shares outstanding.
