Companies to hold a joint conference call on August 14, 2026 at 10 a.m. ET
SAN DIEGO and ALDERLEY PARK, United Kingdom, Aug. 14, 2026 (GLOBE NEWSWIRE) — Skye Bioscience, Inc. (“Skye”) (Nasdaq: SKYE), and Redx Pharma Limited (“Redx”), a U.K. based, privately-held clinical-stage biotechnology company focused on developing novel, small molecule, targeted medicines for fibrotic disease, today announced that they have entered into a definitive transaction agreement (the “Transaction Agreement”).
Under the Transaction Agreement, Skye will acquire the entire issued share capital of Redx via a scheme of arrangement (the “Scheme of Arrangement”) under Part 26 of the U.K. Companies Act 2006 (the “Transaction”). Upon completion of the Transaction in accordance with the Transaction Agreement, the combined company will be led by Redx’s current management team and board of directors, plans to operate under the name Fibrx Therapeutics, Inc. (“Fibrx”), and trade on Nasdaq.
In connection with the Transaction, a number of financing components were executed which together will provide the combined company with aggregate gross proceeds of approximately $125 million. This includes Skye entering into a securities purchase agreement with a syndicate of new and existing leading healthcare investors including Abingworth, British Business Bank1, NEXTBio Capital and 5AM Ventures, as well as Redx’s existing major shareholder, Redmile, for a private placement financing of approximately $68 million in gross proceeds that is expected to close immediately after the closing of the Transaction (the “PIPE Financing”).
Additionally, Redx entered into a subscription agreement for a Series A financing of $36 million in gross proceeds, which was led by new Redx investor, Abingworth, and included British Business Bank and Redx’s existing major shareholder, Redmile (the “Series A Financing” and, together with the PIPE Financing, the “Financing”). The Series A Financing has been approved by the Redx board of directors and, subject to Redx shareholder approval, is expected to close within the next few days.
Further to this, in connection with the PIPE Financing, Skye also entered into an agreement with a fund affiliated with Redmile for a committed equity line facility of up to $22 million (the “Equity Line Facility”), which supports the PIPE Financing described above, and pursuant to which Skye will, at the closing of the Transaction, issue to Redmile a warrant to purchase shares of common stock valued at $5 million on the terms set forth therein (the “Redmile Warrant”).
The boards of directors of both companies have unanimously approved the Transaction, with an expected close in Q4 2026, subject to certain closing conditions, as outlined below. In connection with the Transaction, certain shareholders of Skye and Redx have entered into voting and support agreements pursuant to which they have agreed to vote their shares in favor of the Transaction.
Upon completion of the Transaction, the combined company’s cash and cash equivalents balance, including the funds from the Financing, is expected to fund Fibrx’s operations into 2029 and through key clinical milestones, including topline data from the RXC008 Phase 2 clinical study, expected in H2 2028.
Strategic Rationale for the Transaction
The combined company, Fibrx, will focus on advancing certain fibrosis assets of Redx through clinical and pre-clinical development. The lead asset, RXC008, is a potential first-in-class GI-restricted pan-ROCK inhibitor for the treatment of fibrostenotic Crohn’s disease which is now ready to commence a Phase 2 clinical study in patients. There are no current approved therapeutic treatment options to address the underlying fibrotic aspects of this disease, with surgical intervention often required. In pre-clinical studies, Redx has demonstrated the potential to reverse the formation of fibrosis in the GI-tract which would revolutionize treatment options for this patient population if demonstrated in clinical trials. Data from the Phase 1 study showed favorable tolerability and tissue exposure with no clinically relevant systemic breakthrough or hypotension observed, and a favorable safety profile with no serious adverse events reported. These data were presented at the European Crohn’s and Colitis Organization congress (ECCO) 2025 and Digestive Disease Week (DDW) 2025. RXC008 has an open Investigational New Drug (IND) application in the U.S. and was granted FDA Fast Track designation in January 2026.
“This transaction gives Redx the capital and the platform to progress our pipeline and deliver the Phase 2 program for our lead asset, RXC008, a GI-restricted pan-ROCK inhibitor. We believe this is an exciting opportunity to be a leader in developing a therapeutic option for patients suffering with fibrostenotic Crohn’s disease, considered by many to be one of the largest unmet medical needs in IBD, by directly targeting fibrosis in stricturing disease for which there is currently no treatment option other than surgery,” said Lisa Anson, Redx’s Chief Executive Officer. “We are delighted to have attracted a number of leading institutional biotech investors, and the Nasdaq listing will facilitate engagement with a deep pool of capital that will be required to support our future growth. We are excited to be launching Fibrx as a clinical-stage fibrosis-focused company with the prospect of creating substantial value for investors while delivering a meaningful positive impact for patients.”
“Over the last several months, Skye has evaluated a wide range of options to maximize shareholder value, including an assessment of our internal pipeline, financing opportunities and strategic alternatives,” said Punit Dhillon, President and Chief Executive Officer of Skye. “We believe this transaction provides our shareholders a compelling opportunity to realize both short- and long-term value creation through Redx’s novel anti-fibrotic therapies, led by their first-in-class pan-ROCK inhibitor, RXC008. In addition, Skye shareholders will receive a contingent value right entitling them to receive 90% of net cash proceeds that may be realized for the monetization by the combined company of nimacimab and its associated intellectual property.”
Transaction Highlights
- Combined Company Expected to be Funded into 2029 and Through Key Value Inflection Points
- Combined Company to Advance Redx’s Pipeline of Novel Anti-Fibrotic Therapeutics:
- GI-restricted pan-ROCK Inhibitor, RXC008: An oral, GI-restricted pan-ROCK inhibitor being developed as a potential treatment for fibrostenotic Crohn’s disease, ready to commence a Phase 2 clinical study with topline data expected in H2 2028.
- Discoidin Domain Receptor Inhibitor: A pre-clinical discoidin domain receptor (DDR) inhibitor program with five distinct chemical series and multiple patents across both dual DDR1/DDR2, and selective inhibitors.

IND submission for a DDR inhibitor is expected in 2027.
- Selective ROCK2 Inhibitor, Zelasudil, (RXC007): A next-generation selective ROCK2 inhibitor, with potential for use in interstitial lung diseases and multiple other fibrotic indications such as MASH and cancer-associated fibrosis. RXC007 has completed a successful signal searching Phase 2 clinical program in idiopathic pulmonary fibrosis (IPF) patients and is a candidate for partnering.
- Experienced Leadership Team: Upon completion of the Transaction, the current Redx management team will transition to lead the combined company, Fibrx, with Lisa Anson as Chief Executive Officer. Lisa is an experienced global biopharma leader whose career includes 20-years at AstraZeneca plc. Peter Collum, currently Redx’s Chief Financial Officer based in the U.S., will serve as Fibrx’s CFO. Dr. Mei-Lun Wang, a pediatric gastroenterologist with over 25 years of clinical practice and industry experience, will join Fibrx as Chief Medical Officer. Both Dr. Caroline Phillips, Redx’s Chief Scientific Officer and Dr. Cliff Jones, Redx’s Chief Technical Officer, who have been at Redx for over ten years and who have led multiple successful drug development programs, will remain in their executive positions at the combined company.
- Redx Board to Comprise a Majority of the Board of Combined Company: It is expected that the current members of the Redx board of directors will form a majority of the board of directors of the combined company upon completion of the Transaction. The combined company will be headquartered in Alderley Park, U.K., the current headquarters of Redx.

The percentage ownership of the combined company that Skye stockholders will own as of the closing of the Transaction is subject to adjustment based on the estimated amount of Skye’s net cash immediately prior to the closing date.
