NEW YORK, Aug. 01, 2023 (GLOBE NEWSWIRE) -- TG Therapeutics, Inc. (NASDAQ: TGTX) today announced its financial results for the second quarter ended June 30, 2023, along with recent company developments, and a business outlook for 2023.

Michael S. Weiss, the Company's Chairman and Chief Executive Officer, stated, “We are pleased to report our second quarter 2023 results, representing our first full quarter of BRIUMVI sales, which exceeded our expectations. It’s been gratifying to see BRIUMVI adopted by such a broad range of MS centers and providers so early into our launch and we are humbled when we hear positive feedback on patients’ experience with BRIUMVI. With its glycoengineering for efficient B-cell depletion, lowest reported annualized relapse rates of any CD20 agent in RMS Phase 3 trials and rapid and reliable 1-hour infusion, a number of providers have already made BRIUMVI their CD20 of choice in RMS. I believe our quarterly performance showcases the unwavering dedication of our team, and the potential of BRIUMVI, to improve the lives of patients with MS.” Mr. Weiss continued, “With an ex-U.S. partner in place, we can continue to focus our now enhanced resources on our U.S. commercial launch. I believe our team has executed well on our early launch plan and we are looking forward to building on this momentum as we move forward with the next phase of our launch strategy.”

Financial Results for the Three and Six Months Ended June 30, 2023

• Product Revenue, Net: Product revenue, net was approximately $16.0 million and $23.8 million for the three and six months ended June 30, 2023, compared to $0.6 million and $2.5 million for the three and six months ended June 30, 2022. Product revenue, net for the three and six months ended June 30, 2023, consisted of net product sales of BRIUMVI in the U.S., which was commercially launched in late January 2023. Product revenue, net for the three and six months ended June 30, 2022, consisted of net product sales of UKONIQ™ (umbralisib), which was withdrawn from the U.S. market in May of 2022.
• R&D Expenses: Total research and development (R&D) expense was $28.1 million and $44.0 million for the three and six months ended June 30, 2023, compared to $26.9 million and $74.9 million for the three and six months ended June 30, 2022. The decrease in R&D expense during the six months ended June 30, 2023 was primarily attributable to reduced manufacturing expense and clinical trial related expenses, offset by an increase in license milestone expense of approximately $6.0 million during the six months ended June 30, 2023. Prior to the approval of BRIUMVI, manufacturing costs pertaining to BRIUMVI were expensed to R&D expense in the period incurred, and following approval are reflected in inventory.
• SG&A Expenses: Total selling, general and administrative (SG&A) expense was $30.7 million and $58.8 million for the three and six months ended June 30, 2023, compared to $12.6 million and $33.2 million for the three and six months ended June 30, 2022. The increase was primarily due to non-cash compensation SG&A expenses incurred, and other costs, including personnel, associated with the commercialization of BRIUMVI during the three and six months ended June 30, 2023.
• Net Loss: Net loss was $47.6 million and $86.8 million for the three and six months ended June 30, 2023, compared to $40.5 million and $109.5 million for the three and six months ended June 30, 2022. Excluding non-cash compensation, the net loss for the three and six months ended June 30, 2023, was approximately $35.1 million and $67.5 million, compared to a net loss of $41.5 million and $108.4 million for the three and six months ended June 30, 2022.
• Cash Position and Financial Guidance: Cash, cash equivalents and investment securities were $144.9 million as of June 30, 2023. We anticipate that our cash, cash equivalents and investment securities as of June 30, 2023, combined with the upfront payment of $140.0 million received as part of our ex-U.S. commercialization agreement and projected revenues associated with the sale of BRIUMVI in the U.S. and ex-U.S., will be sufficient to fund our planned operations for the foreseeable future.

ABOUT BRIUMVI^® (ublituximab-xiiy) 150 mg/6 mL Injection for IV
BRIUMVI is a novel monoclonal antibody that targets a unique epitope on CD20-expressing B-cells. Targeting CD20 using monoclonal antibodies has proven to be an important therapeutic approach for the management of autoimmune disorders, such as RMS. BRIUMVI is uniquely designed to lack certain sugar molecules normally expressed on the antibody. Removal of these sugar molecules, a process called glycoengineering, allows for efficient B-cell depletion at low doses.

BRIUMVI is indicated for the treatment of adults with relapsing forms of multiple sclerosis (RMS), to include clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease.

IMPORTANT SAFETY INFORMATION
Contraindications: BRIUMVI is contraindicated in patients with:

• Active Hepatitis B Virus infection
• A history of life-threatening infusion reaction to BRIUMVI

WARNINGS AND PRECAUTIONS

Infusion Reactions: BRIUMVI can cause infusion reactions, which can include pyrexia, chills, headache, influenza-like illness, tachycardia, nausea, throat irritation, erythema, and an anaphylactic reaction. In MS clinical trials, the incidence of infusion reactions in BRIUMVI-treated patients who received infusion reaction-limiting premedication prior to each infusion was 48%, with the highest incidence within 24 hours of the first infusion. 0.6% of BRIUMVI-treated patients experienced infusion reactions that were serious, some requiring hospitalization.

Observe treated patients for infusion reactions during the infusion and for at least one hour after the completion of the first two infusions unless infusion reaction and/or hypersensitivity has been observed in association with the current or any prior infusion. Inform patients that infusion reactions can occur up to 24 hours after the infusion. Administer the recommended pre-medication to reduce the frequency and severity of infusion reactions. If life-threatening, stop the infusion immediately, permanently discontinue BRIUMVI, and administer appropriate supportive treatment. Less severe infusion reactions may involve temporarily stopping the infusion, reducing the infusion rate, and/or administering symptomatic treatment.

Infections: Serious, life-threatening or fatal, bacterial and viral infections have been reported in BRIUMVI-treated patients. In MS clinical trials, the overall rate of infections in BRIUMVI-treated patients was 56% compared to 54% in teriflunomide-treated patients. The rate of serious infections was 5% compared to 3% respectively. There were 3 infection-related deaths in BRIUMVI-treated patients. The most common infections in BRIUMVI-treated patients included upper respiratory tract infection (45%) and urinary tract infection (10%). Delay BRIUMVI administration in patients with an active infection until the infection is resolved.

Consider the potential for increased immunosuppressive effects when initiating BRIUMVI after immunosuppressive therapy or initiating an immunosuppressive therapy after BRIUMVI.

Hepatitis B Virus (HBV) Reactivation: HBV reactivation occurred in an MS patient treated with BRIUMVI in clinical trials. Fulminant hepatitis, hepatic failure, and death caused by HBV reactivation have occurred in patients treated with anti-CD20 antibodies. Perform HBV screening in all patients before initiation of treatment with BRIUMVI. Do not start treatment with BRIUMVI in patients with active HBV confirmed by positive results for HBsAg and anti-HB tests. For patients who are negative for surface antigen [HBsAg] and positive for HB core antibody [HBcAb+] or are carriers of HBV [HBsAg+], consult a liver disease expert before starting and during treatment.

Progressive Multifocal Leukoencephalopathy (PML): Although no cases of PML have occurred in BRIUMVI-treated MS patients, JCV infection resulting in PML has been observed in patients treated with other anti-CD20 antibodies and other MS therapies.

If PML is suspected, withhold BRIUMVI and perform an appropriate diagnostic evaluation. Typical symptoms associated with PML are diverse, progress over days to weeks, and include progressive weakness on one side of the body or clumsiness of limbs, disturbance of vision, and changes in thinking, memory, and orientation leading to confusion and personality changes.

MRI findings may be apparent before clinical signs or symptoms; monitoring for signs consistent with PML may be useful. Further investigate suspicious findings to allow for an early diagnosis of PML, if present. Following discontinuation of another MS medication associated with PML, lower PML-related mortality and morbidity have been reported in patients who were initially asymptomatic at diagnosis compared to patients who had characteristic clinical signs and symptoms at diagnosis.

If PML is confirmed, treatment with BRIUMVI should be discontinued.

Vaccinations: Administer all immunizations according to immunization guidelines: for live or live-attenuated vaccines at least 4 weeks and, whenever possible at least 2 weeks prior to initiation of BRIUMVI for non-live vaccines. BRIUMVI may interfere with the effectiveness of non-live vaccines. The safety of immunization with live or live-attenuated vaccines during or following administration of BRIUMVI has not been studied. Vaccination with live virus vaccines is not recommended during treatment and until B-cell repletion.

Vaccination of Infants Born to Mothers Treated with BRIUMVI During Pregnancy: In infants of mothers exposed to BRIUMVI during pregnancy, assess B-cell counts prior to administration of live or live-attenuated vaccines as measured by CD19⁺ B-cells. Depletion of B-cells in these infants may increase the risks from live or live-attenuated vaccines. Inactivated or non-live vaccines may be administered prior to B-cell recovery. Assessment of vaccine immune responses, including consultation with a qualified specialist, should be considered to determine whether a protective immune response was mounted.

Fetal Risk: Based on data from animal studies, BRIUMVI may cause fetal harm when administered to a pregnant woman. Transient peripheral B-cell depletion and lymphocytopenia have been reported in infants born to mothers exposed to other anti-CD20 B-cell depleting antibodies during pregnancy. A pregnancy test is recommended in females of reproductive potential prior to each infusion. Advise females of reproductive potential to use effective contraception during BRIUMVI treatment and for 6 months after the last dose.

Reduction in Immunoglobulins: As expected with any B-cell depleting therapy, decreased immunoglobulin levels were observed. Decrease in immunoglobulin M (IgM) was reported in 0.6% of BRIUMVI-treated patients compared to none of the patients treated with teriflunomide in RMS clinical trials. Monitor the levels of quantitative serum immunoglobulins during treatment, especially in patients with opportunistic or recurrent infections, and after discontinuation of therapy until B-cell repletion. Consider discontinuing BRIUMVI therapy if a patient with low immunoglobulins develops a serious opportunistic infection or recurrent infections, or if prolonged hypogammaglobulinemia requires treatment with intravenous immunoglobulins.

Most Common Adverse Reactions: The most common adverse reactions in RMS trials (incidence of at least 10%) were infusion reactions and upper respiratory tract infections.

ABOUT MULTIPLE SCLEROSIS
Relapsing multiple sclerosis (RMS) is a chronic demyelinating disease of the central nervous system (CNS) and includes people with relapsing-remitting multiple sclerosis (RRMS) and people with secondary progressive multiple sclerosis (SPMS) who continue to experience relapses. RRMS is the most common form of multiple sclerosis (MS) and is characterized by episodes of new or worsening signs or symptoms (relapses) followed by periods of recovery. It is estimated that nearly 1 million people are living with MS in the United States and approximately 85% are initially diagnosed with RRMS.^1,2 The majority of people who are diagnosed with RRMS will eventually transition to SPMS, in which they experience steadily worsening disability over time. Worldwide, more than 2.3 million people have a diagnosis of MS.¹
