"In the Phase 3 IKEMA study, the addition of Sarclisa to carfilzomib and dexamethasone reduced risk of disease progression or death by 45%," said Thomas G. Martin, M.D., Associate Director, Myeloma Program, The University of California, San Francisco, Professor of Medicine, Adult Leukemia and Bone Marrow Transplantation Program and co-leader of the Hematopoietic Malignancies Program, Helen Diller Family Comprehensive Cancer Center. "This approval is an important advancement for patients whose disease has relapsed and reinforces the potential for Sarclisa to become a standard of care in relapsed or refractory multiple myeloma."

This marks the second FDA approval for Sarclisa, which is also approved in combination with pomalidomide and dexamethasone (pom-dex) for the treatment of adults with RRMM who have received at least two prior therapies including lenalidomide and a proteasome inhibitor.

"Treatment of patients with relapsed or refractory multiple myeloma remains challenging and the prognosis for patients experiencing multiple relapses unfortunately is poor," said Peter C. Adamson, M.D., Global Development Head, Oncology and Pediatric Innovation at Sanofi. "With this approval, Sarclisa is now included in two standard of care regimens for the treatment of patients with multiple myeloma as early as first relapse. Today’s milestone further supports our ambition for Sarclisa to become the anti-CD38 of choice for patients with relapsed or refractory multiple myeloma."

Sarclisa Phase 3 IKEMA pivotal trial results supporting approval

The FDA approval is based on data from the Phase 3 IKEMA study, a randomized, multi-center, open label clinical trial that enrolled 302 patients with relapsed multiple myeloma across 69 centers spanning 16 countries.1 In this study, Sarclisa added to Kd (Sarclisa combination therapy) reduced the risk of disease progression or death by 45% (hazard ratio 0.548, 95% CI 0.366-0.822, p=0.0032) versus standard of care Kd alone in patients with multiple myeloma. The median progression free survival (PFS) for Sarclisa combination therapy was not reached at the time of the pre-planned interim analysis. This study enrolled a difficult-to-treat patient population, including those who are elderly, have high cytogenetic risk or renal impairment. Overall, demographic and disease characteristics at baseline were balanced between the two treatment groups.2

Secondary endpoints of the IKEMA trial assessed the overall response rate (ORR) for Sarclisa combination therapy compared to Kd, including complete response (CR) and very good partial response (VGPR). There was no statistically significant difference in ORR, which remained similar for each arm at 86.6% for the Sarclisa combination therapy versus 82.9% for Kd (p=0.3859). The rate of CR was 39.7% in the Sarclisa combination therapy arm and 27.6% in the Kd arm. The rate of VGPR was 33% for patients receiving Sarclisa combination therapy and 28.5% for patients receiving Kd.2 At the time of the interim analysis, overall survival (OS) data were still immature.3

The most frequent adverse reactions (occurring in 20% or more of patients) for Sarclisa versus the control arm were upper respiratory tract infection (67% vs. 57%), infusion-related reactions (46% vs. 3.3%), fatigue (42% vs. 32%), hypertension (37% vs. 32%), diarrhea (36% vs. 29%), pneumonia (36% vs. 30%), dyspnea (29% vs. 24%), bronchitis (24% vs. 13%), and cough (23% vs. 15%). Serious adverse reactions that occurred in more than 5% of patients who received Sarclisa combination therapy were pneumonia (25%) and upper respiratory tract infections (9%). Permanent discontinuation of treatment because of adverse reactions (Grade 1-4) occurred in 8% of patients treated with Sarclisa combination therapy, and 2.8% of patients discontinued due to an infection.2

Multiple Myeloma: an incurable blood cancer, with significant burden

Multiple Myeloma (MM) is the second most common hematologic malignancy4, affecting more than 130,000 patients in the United States; approximately 32,000 Americans are diagnosed with multiple myeloma each year.5 Despite available treatments, MM remains an incurable malignancy, and is associated with significant patient burden. Since MM does not have a cure, most patients will relapse. Relapsed MM is the term for when the cancer returns after treatment or a period of remission. Refractory MM refers to when the cancer does not respond or no longer responds to therapy.

About Sarclisa

Sarclisa is a monoclonal antibody that binds to a specific epitope on the CD38 receptor on MM cells. It is designed to work through multiple mechanisms of action including programmed tumor cell death (apoptosis) and immunomodulatory activity. CD38 is highly and uniformly expressed on the surface of MM cells, making it a potential target for antibody-based therapeutics such as Sarclisa.

This marks the second FDA approval for Sarclisa since March 2020 and comes more than three months ahead of the FDA’s target action date. In February, the European Medicines Agency’s Committee for Medicinal Products for Human Use adopted a positive opinion for a second indication for Sarclisa, in combination with carfilzomib and dexamethasone (Kd), for the treatment of adult patients with multiple myeloma who have received at least one prior therapy. The use of Sarclisa in combination with Kd is not currently approved in the European Union (EU), but the final decision whether to expand the indication is expected from the European Commission in the coming months. In Europe, Sarclisa is indicated in combination with pom-dex for the treatment of adult patients with RRMM who have received at least two prior therapies including lenalidomide and a proteasome inhibitor and have demonstrated disease progression on the last therapy. Outside of the U.S. and the EU, Sarclisa is approved in Switzerland, Canada, Australia, Japan, Russia, the UAE, South Korea, Taiwan and Brazil in combination with pom-dex for the treatment of certain adults with RRMM.

Sarclisa continues to be evaluated in multiple ongoing Phase 3 clinical trials in combination with current standard and novel treatments across the MM treatment continuum. It is also under investigation for the treatment of other hematologic malignancies and solid tumors. The use of Sarclisa in these additional settings is currently under clinical investigation and its safety and efficacy have not been fully evaluated by any regulatory authority.

IMPORTANT SAFETY INFORMATION AND INDICATION FOR U.S. PATIENTS

What is SARCLISA?

SARCLISA is a prescription medicine used in combination with:

The medicines pomalidomide and dexamethasone, to treat adults who have received at least 2 prior therapies including lenalidomide and a proteasome inhibitor to treat multiple myeloma.

"Kiromic BioPharma achieved important scientific and operational milestones during the year that we believe have us well positioned for preparing our staff and our facilities for the first in-human dosing in Q3 2021," said Dr. Maurizio Chiriva-Internati, CEO and President of Kiromic BioPharma. "We are thankful to our employees and collaborators who have maintained this high level of execution in the middle of the hard challenges posed by the COVID-19 pandemic."

Our approach and goal is to defeat cancer by developing immunotherapies that rely on improving target discovery and validation. With better targets, we believe our therapies will be more effective than the current array of immunotherapies using older targets.

Corporate and Scientific Highlights

Initial Public Offering Completion – On October 20, 2020, we completed our IPO, raising $15 million of gross proceeds, significantly strengthening the Company’s balance sheet to support the continued development of our promising pipeline of targeted cancer therapies.

Two IND Application Filings – On December 17, 2020 we filed two applications with the U.S. Food and Drug Administration ("FDA"). The first IND was for a Phase 1 clinical trial of intravenously ("IV") administered allogeneic CAR-T for epithelial ovarian carcinoma ("EOC") and malignant pleural mesothelioma ("MPM"). The second IND was for a Phase 1 clinical trial of an intrapleural/intraperitoneal (IP) administered allogeneic CAR-T for EOC and MPM.

Since filing the original INDs in December 2020, the Company has had communications with the FDA, and numerous consults with scientific board and clinical advisors regarding resubmission. In March 2021, we announced that we planned to resubmit the two INDs.

The revised INDs will be for first in-human dosing of our Off-the-Shelf, Allogeneic Gamma-Delta T cell therapy for metastatic and progressive locally advanced solid malignancies.

The revised INDs have protocols which retain approximately 80% of the original INDs.

Longwood University Licensing Agreement – On November 30, 2020, we executed a licensing agreement for chPD1 with Longwood University. This marks a major milestone for Kiromic CAR-T development. With chPD1, we believe our chimeric PD1 CAR-T will be able to overcome the challenging tumor micro-environment (TME) which has plagued other CAR-T programs, while making Kiromic the only CAR-T development program with a built-in capability to meet other CAR-T programs head-on who do not have a bundled chPD1 CAR-T.

GMP Facility Completion – As of September 30, 2020, the key features of the GMP facility have been completed, clearing the path for the production of off-the-shelf Gamma-Delta-T cells, a novel approach to CAR-T cell therapy, which will be evaluated in the upcoming clinical trials.
FY 2020 Financial Highlights

Cash Position: Cash and cash equivalents were $10,150,500 as of December 31, 2020, compared to $1,929,100 as of December 31, 2019. The increase was primarily due to cash inflows of $15,805,600 attributable to financing activities related to the issuance of common stock from the initial public offering, issuance of Series B Preferred Stock and proceeds net of repayments from the Paycheck Protection Program loan. These inflows were offset by outflows of $6,126,600 and $1,457,600 attributable to operating activities and investing activities, respectively.

R&D Expenses: Research and development expenses were $5,052,900 for the year ended December 31, 2020, compared to $1,201,700 for the year ended December 31, 2019. The increase was primarily attributable to augmented headcount, increased square footage to our Houston, TX leased facilities, in-vitro experimentation costs, and intellectual property costs.

G&A Expenses: General and administrative expenses were $14,144,000 for the year ended December 31, 2020, compared to $2,503,700 for the year ended December 31, 2019. This increase was primarily due to increased stock compensation expenses and personnel expenses.

Net Loss: Net loss was $19,200,200 for the year ended December 31, 2020, compared to a net loss of $3,727,900 for the year ended December 31, 2019.

Dr. Chiriva-Internati continued, "Developing live-cell therapies by leveraging artificial intelligence is central to transforming the cost and efficiency of the immune-oncology field and improving the potential for off-the-shelf therapies for cancer patients. We believe our approach will help us design more efficient pre-clinical validation studies and more targeted clinical trials, thereby accelerating our drug candidates’ time to approval and eventually to market. DIAMOND is central to our process in achieving this outcome rapidly and with reduced costs," concluded Dr. Chiriva-Internati.

Guided Therapeutics Closes $2.114 Million Series F Preferred Stock Financing

On March 31, 2021 Guided Therapeutics, Inc. (OTCQB: GTHP), the maker of a rapid and painless testing platform based on its patented biophotonic technology, reported that it had closed its Series F Preferred Stock Financing on March 26, 2021 (Press release, Guided Therapeutics, MAR 31, 2021, View Source [SID1234577454]). This oversubscribed sale of 2,114 Series F Preferred Shares resulted in gross proceeds to the Company of $2,114,000, netting approximately $1,980,000 after legal costs, fees and commissions of approximately $134,000 (6.3%). In addition, as board approved non-cash transactions, three of the Company’s officers exchanged and forgave a total of $321,554 in debt owed to them by the Company into 235 Series F Preferred Shares under the same terms as the non-affiliated cash investors.

The two most important uses of proceeds from the Series F Financing included 1) making the final payment of $750,000 to GPB Holdings, LLC, completed on January 8, 2021, and 2) allocate most of the remainder to completing the U.S. FDA clinical trial for the LuViva Advanced Cervical Scan. The clinical sites currently are reviewing the study protocol that was developed by the Company, which implemented recommendations made by the U.S. FDA. It is expected the trial will begin in the second quarter of 2021. The Company’s primary objective this year is completing the clinical trial of approximately 400 women and filing the results with the FDA.

The Series F Preferred shares are convertible at a fixed price of 25 cents per share, carry a 6% annual dividend and could potentially include an additional dividend of 15% after twelve months if the Company is unable to uplist to a national exchange or complete its FDA study. The dividends can be paid in cash or common shares at the option of the Company. Aspen Capital acted as Financial Advisor to the Company with respect to certain Canadian investments.

"Now that the Series F Financing has closed, netting sufficient funds, we can turn our full attention to completing the FDA study without delay," said Gene Cartwright, Guided Therapeutics CEO, adding, "At the same time, we have made great strides in cleaning up our balance sheet and have significantly reduced our liabilities, thereby setting the stage for a potential uplist to a national exchange, concomitant with the U.S. FDA study and significant progress in China."
