• CNTB101: An investigational anti-IL-17 A/F antibody being developed for chronic inflammatory conditions such as psoriasis, psoriatic arthritis, and ankylosing spondylitis.
• CNTB102: An investigational S1P1 modulator currently in development for the treatment of ulcerative colitis, an inflammatory bowel disease.

Connect Biopharma (symbol: CNTB) is a clinical-stage biopharmaceutical company focused on the discovery and development of next-generation immune modulators for the treatment of inflammatory diseases.

As a clinical-stage company, Connect Biopharma has publicly stated in its SEC filings (including its 2022 10-K and subsequent 10-Q filings) that it has not generated any revenue from product sales to date.

Therefore, Connect Biopharma does not currently have "major customers" in the traditional sense of companies or individuals purchasing its products or services. Its operations are primarily funded through financing activities, such as the issuance of equity (e.g., private placement of convertible preferred shares and warrants, and ordinary shares in connection with its initial public offering).

For a company at this stage, future potential revenue, and thus future "customers" or partners, would typically come from collaboration agreements, licensing deals, or milestone payments with larger pharmaceutical companies, should their drug candidates successfully advance through clinical development and eventually receive regulatory approval.

• For Atopic Dermatitis and Asthma, their CBP-201 (an IL-4Rα antibody) faces an immense challenge from the deep market penetration and ongoing indication expansion of Dupilumab (Dupixent) by Regeneron and Sanofi. Dupixent has set a very high bar for efficacy and safety, making it exceptionally difficult for new IL-4Rα antibodies or similar mechanisms to differentiate themselves and capture significant market share. This competitive pressure is further intensified by the approval and development of other highly efficacious biologics (e.g., IL-13 inhibitors) and oral JAK inhibitors.
• For Inflammatory Bowel Disease, their CBP-307 (an S1P1 agonist) contends with a crowded market already served by multiple approved S1P modulators (e.g., Ozanimod, Etrasimod) and JAK inhibitors (e.g., Tofacitinib, Upadacitinib) from large pharmaceutical companies. The continuous introduction of new biologics and small molecules in this space demands a high degree of differentiation in terms of efficacy, safety, or patient convenience for any new market entrant.

Connect Biopharma (CNTB) focuses on developing therapies for inflammatory diseases, with its primary product candidate being rademikibart (formerly CBP-201).

Rademikibart (CBP-201)

• Asthma and Chronic Obstructive Pulmonary Disease (COPD): Rademikibart is being developed for applications in asthma and COPD, particularly for acute exacerbations. The combined addressable markets for these conditions represent multi-billion-dollar commercial opportunities globally. Independent market analyses project potential peak annual worldwide sales exceeding $3 billion for asthma and $2 billion for COPD. In the U.S. alone, approximately 1 million asthma patients and 1.3 million COPD patients experience acute exacerbations annually, indicating a significant unmet need and untapped opportunity. Market research also forecasts approximately $5 billion for both asthma and COPD for acute and chronic treatment.
• Atopic Dermatitis (AD): While Connect Biopharma is not currently pursuing global development of rademikibart for atopic dermatitis, its partner, Simcere Pharmaceuticals, is developing and commercializing it for this indication in Greater China. The estimated global market for atopic dermatitis was approximately $10.4 billion in 2020 and is projected to grow to $19.3 billion by 2025.

Icanbelimod (CBP-307)

• Ulcerative Colitis (UC): Icanbelimod is under development for the treatment of ulcerative colitis. While there is an acknowledged need for additional safe and effective therapies for UC, with a "therapeutic ceiling" meaning many patients do not achieve clinical remission, specific addressable market sizes for this product candidate were not explicitly detailed in the available information.

Connect Biopharma previously had another product candidate, CBP-174, for pruritus associated with atopic dermatitis, but the company terminated its license agreement for CBP-174 in May 2024 to prioritize its other lead programs.

Connect Biopharma (CNTB) has several anticipated drivers of future revenue growth over the next 2-3 years, primarily centered around its lead drug candidate, rademikibart:

1. Approval and Commercialization of Rademikibart for Atopic Dermatitis in China: Connect Biopharma's exclusive licensee in Greater China, Simcere Pharmaceutical Co., Ltd., submitted a New Drug Application (NDA) for rademikibart for the treatment of atopic dermatitis (AD) in adults and adolescents to China's National Medical Products Administration (NMPA) in July 2025. Anticipated approval around mid-2026 is expected to trigger significant milestone payments and tiered royalties on net sales to Connect Biopharma, contributing to revenue growth.
2. Advancement and Potential Approval of Rademikibart for Acute Asthma and COPD Exacerbations in the U.S.: Connect Biopharma is currently conducting Phase 2 Seabreeze STAT studies in the U.S. for rademikibart as an adjunctive treatment for acute exacerbations of asthma and chronic obstructive pulmonary disease (COPD). Topline data from these trials is expected in the first half of 2026. Positive results and subsequent progression towards regulatory approval could open up a significant market opportunity, as no biologic therapies are currently approved for acute exacerbations in these conditions, positioning rademikibart as a potential first-mover with a differentiated, rapid onset of action.
3. Expansion into Chronic Treatment for Asthma and COPD in the U.S.: Beyond the immediate focus on acute exacerbations, Connect Biopharma believes rademikibart has the potential for broader chronic utilization in asthma and COPD. Successful development and commercialization in the acute setting could pave the way for expanding rademikibart's label to include chronic treatment, thereby significantly enlarging the addressable patient population and driving further revenue growth.
4. Additional Milestone Payments and Royalties from the Simcere Partnership: The licensing agreement with Simcere for Greater China includes potential development and commercial milestone payments totaling up to $110 million, in addition to tiered royalties on net sales. Future regulatory approvals for rademikibart in other indications within China (such as chronic asthma, for which Simcere is conducting a large study) would unlock further milestone payments and royalty streams, contributing to Connect Biopharma's revenue.

Share Issuance

• Connect Biopharma completed its Initial Public Offering (IPO) in March 2021, issuing 11,250,000 American Depositary Shares (ADSs) at $17.00 per ADS, generating approximately $191.3 million in gross proceeds.
• In September 2025, the company terminated its American Depositary Receipt (ADR) program and directly listed its ordinary shares on Nasdaq, exchanging ADRs for ordinary shares at a one-for-one ratio to enhance institutional visibility and eliminate depositary fees.

Inbound Investments

• In 2024, Connect Biopharma recognized $26.0 million in revenue, primarily from a license agreement with Simcere Pharmaceutical Co., Ltd., which included an upfront fee, development milestones, and cost reimbursements for exclusive rights to rademikibart in Greater China.
• The company is eligible to receive up to an additional $110 million in milestone payments from the Simcere agreement upon achieving certain development, regulatory, and commercial milestones.

Capital Expenditures

• Research and development (R&D) expenses were $29.3 million for the year ended December 31, 2024, a decrease from $53.0 million in 2023, primarily due to the completion of the rademikibart global Phase 2b program in chronic asthma and China pivotal trials for atopic dermatitis.
• R&D expenses increased to $15.4 million for the six months ended June 30, 2025, from $14.0 million in the same period of 2024, mainly driven by increased rademikibart-related development costs due to the initiation of Phase 2 clinical trials in asthma and COPD exacerbations in May 2025.
• Connect Biopharma anticipates increasing R&D expenses in 2025 to support the further development of rademikibart, with two Phase 2 trials expected to commence in the first half of 2025.
