"These data provide important support for our commercial-ready manufacturing process and reinforce our confidence in the consistency and quality of the product candidate being delivered to patients," said Gavin MacBeath, Ph.D., Chief Executive Officer. "We are very encouraged by the 11 of 14 patients who showed complete donor chimerism approximately three weeks after their first infusion as well as the complete chimerism seen in all 5 patients who were assessed after their second infusion of TSC-101. Furthermore, even in a higher-risk patient population when compared to patients in Cohort A and our control arm, 93% of patients responded to TSC-101 with decreasing recipient chimerism. Taken together, these findings support our planned transition into the pivotal Phase 3 study of TSC-101 this month. We look forward to advancing further development of TSC-101 with the goal of preventing relapse following allo-HCT and improving outcomes for these patients."

"The initial results from Cohort C continue to exhibit strong clinical efficacy while maintaining a positive safety profile in patients receiving TSC-101 after their standard of care allo-HCT," said Chrystal U. Louis, M.D., Chief Medical Officer. "This cohort enrolled ahead of schedule and highlights the strong investigator engagement and growing interest in the TSC-101 clinical development program. As relapse remains a leading cause of death following allo-HCT, we are encouraged by the potential of TSC-101 to address residual disease and thereby improve long-term outcomes for patients with heme disorders."

Key Data Highlights

On June 22, 2026 Ligand Pharmaceuticals Incorporated (Nasdaq: LGND) ("Ligand") reported its intention to offer $550.0 million aggregate principal amount of convertible senior notes due 2031 (the "notes") in a private placement (the "offering") to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the "Securities Act"), subject to market conditions and other factors. Ligand also expects to grant to the initial purchasers of the notes (the "initial purchasers") a 13-day option to purchase up to an additional $82.5 million aggregate principal amount of notes.

Key Elements of the Transaction

The notes will be general unsecured, senior obligations of Ligand and will accrue interest payable semiannually in arrears on March 15 and September 15 of each year, beginning on March 15, 2027. The notes will mature on September 15, 2031, unless earlier converted, redeemed or repurchased. Upon conversion of the notes, Ligand will pay cash up to the aggregate principal amount of the notes to be converted and pay or deliver, as the case may be, cash, shares of Ligand’s common stock or a combination of cash and shares of Ligand’s common stock, at Ligand’s election, in respect of the remainder, if any, of Ligand’s conversion obligation in excess of the aggregate principal amount of the notes being converted. The interest rate, initial conversion rate, redemption or repurchase rights and other terms of the notes will be determined at the time of pricing of the offering.

Use of Proceeds

Ligand expects to use a portion of the net proceeds from the offering to pay the cost of the convertible note hedge transactions described below (after such cost is partially offset by the proceeds to Ligand from the sale of the warrants in the warrant transactions described below). In addition, Ligand expects to use up to $75 million of the net proceeds from the offering to repurchase shares of its common stock from certain purchasers of the notes in privately negotiated transactions, as described below. Ligand intends to use the remaining net proceeds from the offering for general corporate purposes including investing in complementary businesses, companies, products and technologies, although Ligand has no present commitments or agreements to do so beyond its previously announced agreement to acquire Xoma Royalty Corporation. If the initial purchasers exercise their option to purchase additional notes, Ligand expects to sell additional warrants to the option counterparties and use a portion of the net proceeds from the sale of the additional notes, together with the proceeds from the sale of the additional warrants, to enter into additional convertible note hedge transactions and the remaining net proceeds for general corporate purposes.

Convertible Note Hedge Transactions

In connection with the pricing of the notes, Ligand expects to enter into convertible note hedge transactions (the "convertible note hedge transactions") with one or more of the initial purchasers or their respective affiliates and/or other financial institutions (the "option counterparties"). Ligand also expects to enter into warrant transactions (the "warrant transactions") with the option counterparties, pursuant to which Ligand will issue warrants to purchase common stock (the "warrants") to such option counterparties. The convertible note hedge transactions are expected generally to reduce the potential dilution to Ligand’s common stock upon any conversion of notes and/or offset any cash payments Ligand is required to make in excess of the principal amount of converted notes, as the case may be. However, the warrant transactions could separately have a dilutive effect on Ligand’s common stock to the extent that the market price per share of common stock exceeds the strike price of the warrants. If the initial purchasers exercise their option to purchase additional notes, Ligand expects to enter into additional convertible note hedge transactions and additional warrant transactions with the option counterparties.

In connection with establishing their initial hedges of the convertible note hedge transactions and the warrant transactions, Ligand expects the option counterparties or their respective affiliates to enter into various derivative transactions with respect to Ligand’s common stock and/or purchase shares of Ligand’s common stock concurrently with or shortly after the pricing of the notes. This activity could increase (or reduce the size of any decrease in) the market price of Ligand’s common stock or the notes at that time.

The option counterparties or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to Ligand’s common stock and/or purchasing or selling shares of Ligand’s common stock or other securities of Ligand in secondary market transactions following the pricing of the notes and prior to the maturity of the notes (and are likely to do so in connection with any conversion, redemption or repurchase of the notes). This activity could also cause or avoid an increase or a decrease in the market price of Ligand’s common stock or the notes, which could affect a holder’s ability to convert its notes and, to the extent the activity occurs during any observation period related to a conversion of notes, it could affect the number of shares of Ligand’s common stock, if any, and value of the consideration, if any, that a holder will receive upon conversion of its notes.

Share Repurchases

In addition, Ligand expects to use up to $75 million of the net proceeds from the offering to repurchase shares of its common stock from certain purchasers of the notes in privately negotiated transactions effected through one of the initial purchasers or an affiliate thereof concurrently with the pricing of the notes. The price per share of Ligand’s common stock repurchased in such transactions is expected to equal the last reported price per share of Ligand’s common stock as of the date of the pricing of the notes. These repurchases could increase (or reduce the size of any decrease in) the market price of Ligand’s common stock prior to, concurrently with or shortly after the pricing of the notes, and could result in a higher effective conversion price for the notes. Ligand cannot predict the magnitude of such market activity or the overall effect it will have on the market price of the notes and/or the market price of Ligand’s common stock.

The notes and the warrants will only be offered to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act. The notes, the warrants, the shares of common stock into which the notes are convertible and the shares of common stock issuable upon exercise of the warrants have not been, and will not be, registered under the Securities Act or the securities laws of any other jurisdiction, and unless so registered, may not be offered or sold in the United States or to, or for the account or benefit of, U.S. persons, absent registration or an applicable exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and other applicable securities laws.

This press release is neither an offer to sell nor a solicitation of an offer to buy any securities, nor shall it constitute an offer to sell, solicitation of an offer to buy or sale of any securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such state or jurisdiction.

"Securing this patent strengthens Genprex’s intellectual property portfolio, providing crucial protection for the therapeutic combinations currently being evaluated in the Acclaim-3 clinical trial," said Thomas Gallagher, Senior Vice President of Intellectual Property and Licensing at Genprex. "This achievement reinforces our competitive advantage and supports our strategy to bring innovative cancer treatments to patients worldwide."

This patent will expand on the previously granted patents for REQORSA in combination with PD-1 and PD-L1 antibodies, which have been granted in the U.S., Japan, Mexico, Russia, Chile, China, Singapore Europe, Korea, Australia and Israel.

REQORSA is initially being developed in combination with prominent, approved cancer drugs to treat lung cancer. In preclinical studies, REQORSA has been shown to be complementary with targeted drugs and immunotherapies. The Company believes REQORSA’s unique attributes position it to provide potential treatments that improve on these current therapies for patients with lung cancer and possibly other cancers.

According to the Canadian Cancer Society, lung and bronchus cancer is the most commonly diagnosed cancer in Canada (excluding non-melanoma skin cancers). It is the leading cause of death from cancer for both men and women in Canada. It is estimated that 32,900 people in Canada will be diagnosed with lung and bronchus cancer in 2026, representing 13% of all new cancer cases. It is also estimated that 19,300 people in Canada will die from lung and bronchus cancer in 2026, representing 22% of all cancer deaths.

About Acclaim-3

Acclaim-3 is a Phase 1/2 clinical trial evaluating the combination of REQORSA and Genentech’s Tecentriq (atezolizumab) as maintenance therapy in patients with extensive stage small cell lung cancer (ES-SCLC) who are candidates for maintenance therapy after receiving Tecentriq and chemotherapy as standard of care initial treatment. In this study, patients will be treated with REQORSA and Tecentriq until disease progression or unacceptable toxicity is experienced.

The Phase 2 expansion study follows the successful completion of the Phase 1 dose escalation portion of the study, which showed REQORSA was generally well tolerated. The Phase 2 expansion portion is expected to enroll approximately 50 patients. The primary endpoint of the Phase 2 portion is to determine the 18-week progression-free survival rate from the time of the start of maintenance therapy with REQORSA and Tecentriq in patients with ES-SCLC. Patients will also be followed for survival. Genprex’s team plans to conduct an interim analysis after the 25th patient enrolled and treated reaches 18 weeks of follow up. The Acclaim-3 clinical trial is supported by U.S. Food and Drug Administration (FDA) Fast Track Designation and Orphan Drug Designation.

"The article, entitled "Adenosine A3 Receptor Agonists as Multisystemic Disease Modifiers: From Molecular Signaling to Clinical Translation" was published in the peer-reviewed Biomolecules Journal (link). The publication reviews findings from Can-Fite work and numerous independent academic and clinical research groups worldwide demonstrating that activation of the A3 adenosine receptor (A3AR) modulates key pathological pathways involved

The review details evidence supporting A3AR agonist activity in:

● Solid tumors, including hepatocellular carcinoma and pancreatic cancer
● Metabolic dysfunction-associated steatohepatitis (MASH) and liver fibrosis
● Autoimmune and inflammatory diseases
● Osteoarthritis and musculoskeletal disorders
● Neurodegenerative diseases, including Alzheimer’s disease and vascular dementia
● Obesity and metabolic disorders
● Rare genetic diseases, including Lowe syndrome

"This publication represents an important scientific validation of Piclidenoson and Namodenoson and the broader A3AR platform technology," stated Pnina Fishman, CSO and Chairperson of Can-Fite. "Particularly compelling is the fact that many of the findings summarized in this review originate from independent research institutions worldwide and extend well beyond our current clinical development programs. Collectively, we believe these data reinforce the potential of A3AR agonists to address multiple diseases with significant unmet medical needs."

Can-Fite’s clinical pipeline currently includes Namodenoson in Phase 3 development for hepatocellular carcinoma, Phase 2 development for pancreatic cancer, and Phase 2b development for MASH. Piclidenoson is currently being evaluated in a pivotal Phase 3 study in psoriasis. The publication further supports the Company’s strategy of leveraging A3AR agonists as a platform technology applicable to multiple therapeutic indications.
