Boundless Bio downgraded to Market Perform from Outperform at Leerink
Leerink downgraded Boundless Bio (BOLD) to Market Perform from Outperform with a price target of $3, down from $15. The company is discontinuing current monotherapy and combination arms of BBI-355 in the Phase 1/2 POTENTIATE clinical trial based on a narrow therapeutic index observed with dosing, the analyst tells investors in a research note. The firm is moving to the sidelines pending validation of Boundless Bio's new approach. It removed all value for the CHK1 program until the company validates the BBI-355 and BBI-825 combination hypothesis in specific tumor types. Confident Investing Starts Here:

Boundless Bio discontinuing BBI-355 and BBI-825 programs
Boundless Bio (BOLD) 'provided business updates focused on optimizing the Company's portfolio for patient impact and long-term value-creation. Boundless has been investigating BBI-355, a novel, oral, selective CHK1 inhibitor designed to target replication stress in oncogene-amplified cancers in its ongoing Phase 1/2 POTENTIATE clinical trial. In the trial, which explored different dose levels and dosing regimens, BBI-355 has demonstrated a narrow therapeutic index with continuous every other day dosing (Q2D), resulting from hematological toxicity at or near doses associated with clinical activity. The Company believes BBI-355's narrow therapeutic index makes it suboptimal for continued development as a single agent with continuous dosing. In addition, the combinations of BBI-355 with the EGFR inhibitor erlotinib, and with the FGFR inhibitor futibatinib, were not well-tolerated with Q2D dosing at the exposure levels believed to be required for robust, sustained anti-tumor activity. Based on these findings and market considerations, the Company has decided to discontinue further clinical development in the current arms of the POTENTIATE clinical trial. Boundless's novel Kinesin program targets a previously undrugged kinesin involved in DNA segregation, including ecDNA segregation, during mitosis. The Company has discovered orally bioavailable, highly selective Kinesin degraders that have demonstrated potent anti-tumor activity in a range of cancer cell lines as well as single agent tumor regressions in mouse xenograft cancer models. The Company selected BBI-940 as its development candidate and reaffirmed that it expects to submit an Investigational New Drug (IND) application in the first half of 2026. Boundless expects to deliver initial proof-of-concept clinical data from BBI-940 within its extended cash runway timeline. In connection with its portfolio prioritization, Boundless has streamlined its operations, resulting in an approximately one-third reduction of its workforce. The Company believes the combination of portfolio prioritization, streamlined operations, and its cash, cash equivalents, and short-term investments of $138.3 million as of March 31, 2025, will extend its operating runway into the first half of 2028 and through anticipated clinical proof-of-concept readouts for each of its therapeutic programs.'

Boundless Bio Announces Portfolio Prioritization and Runway Extension
Portfolio prioritization focuses on novel-novel combination therapy of BBI-355 and BBI-825 and new development candidate, BBI-940, for novel kinesin program Operating runway extended into the first half of 2028, through expected proof-of-concept clinical readouts for each program Conference call and webcast to be held Tuesday, May 27 at 8:00 am ET SAN DIEGO, May 23, 2025 (GLOBE NEWSWIRE) -- Boundless Bio (Nasdaq: BOLD), a clinical-stage oncology company interrogating extrachromosomal DNA (ecDNA) biology to deliver transformative therapies to patients with previously intractable oncogene amplified cancers, today provided business updates focused on optimizing the Company's portfolio for patient impact and long-term value-creation. Executive Summary Discontinuing current monotherapy and combination arms of BBI-355 in POTENTIATE clinical trial. Plans to evaluate BBI-355 and BBI-825 as a combination therapy in the POTENTIATE clinical trial, targeting initiation in the second half of 2025. Declared BBI-940 as the development candidate for novel Kinesin program; IND submission on track for the first half of 2026. Streamlined operations, extending the Company's expected cash runway into the first half of 2028, through proof-of-concept clinical milestones for each of its therapeutic programs. 'At Boundless, we're committed to delivering innovative therapies for patients with oncogene-amplified cancers through disciplined execution,' said Zachary Hornby, President and Chief Executive Officer of Boundless Bio. 'By prioritizing the novel combination of BBI-355 and BBI-825, along with our exciting Kinesin program, BBI-940, we're concentrating our resources where we see the greatest potential to develop meaningful medicines. These decisions extend our operating runway into the first half of 2028, which should enable us to reach initial clinical milestones for these programs with our current capital.' BBI-355 and BBI-825 Programs Discontinuing current monotherapy and combination arms of BBI-355 in POTENTIATE clinical trial Boundless has been investigating BBI-355, a novel, oral, selective CHK1 inhibitor designed to target replication stress in oncogene-amplified cancers in its ongoing Phase 1/2 POTENTIATE clinical trial. In the trial, which explored different dose levels and dosing regimens, BBI-355 has demonstrated a narrow therapeutic index with continuous every other day dosing (Q2D), resulting from hematological toxicity at or near doses associated with clinical activity. The Company believes BBI-355's narrow therapeutic index makes it suboptimal for continued development as a single agent with continuous dosing. In addition, the combinations of BBI-355 with the EGFR inhibitor erlotinib, and with the FGFR inhibitor futibatinib, were not well-tolerated with Q2D dosing at the exposure levels believed to be required for robust, sustained anti-tumor activity. Based on these findings and market considerations, the Company has decided to discontinue further clinical development in the current arms of the POTENTIATE clinical trial. Pursuing novel-novel combination for BBI-355 and BBI-825 Last year, Boundless announced its decision to not advance the STARMAP clinical trial of its novel, oral, selective ribonucleotide reductase (RNR) inhibitor, BBI-825. The decision was due, in part, to a lack of dose proportional pharmacokinetic exposure observed at steady-state as a result of BBI-825 inducing its own metabolism in trial subjects following continuous twice daily (BID) dosing. Based on recent studies, the Company believes that there is strong mechanistic rationale to combine BBI-825 with BBI-355 for synergistic anti-tumor activity as a replication stress combination therapy that does not require continuous dosing, nor involve overlapping toxicity. The novel/novel combination demonstrated preclinical evidence of synergistic cytotoxicity in cancer cell lines and tumor regression in mouse xenograft models using weekly dosing at exposures not associated with hematologic toxicity. The company will present additional scientific details supporting this decision during the live webcast on Tuesday, May 27. Boundless plans to initiate clinical development of the BBI-355/BBI-825 combination in 2025 and expects to deliver initial proof-of-concept clinical data within its extended cash runway timeline. Kinesin Program Development candidate BBI-940 declared for novel Kinesin program Boundless's novel Kinesin program targets a previously undrugged kinesin involved in DNA segregation, including ecDNA segregation, during mitosis. The Company has discovered orally bioavailable, highly selective Kinesin degraders that have demonstrated potent anti-tumor activity in a range of cancer cell lines as well as single agent tumor regressions in mouse xenograft cancer models.

Mr. Hornby concluded, 'I want to personally thank our departing team members, whose valuable contributions have helped advance our science and build our company. Their work remains an integral part of our foundation as we continue our important mission for patients.'

Here's Why We're Watching Boundless Bio's (NASDAQ:BOLD) Cash Burn Situation
We can readily understand why investors are attracted to unprofitable companies. For example, biotech and mining exploration companies often lose money for years before finding success with a new treatment or mineral discovery. But the harsh reality is that very many loss making companies burn through all their cash and go bankrupt. So, the natural question for Boundless Bio (NASDAQ:BOLD) shareholders is whether they should be concerned by its rate of cash burn. For the purpose of this article, we'll define cash burn as the amount of cash the company is spending each year to fund its growth (also called its negative free cash flow). Let's start with an examination of the business' cash, relative to its cash burn. View our latest analysis for Boundless Bio A company's cash runway is the amount of time it would take to burn through its cash reserves at its current cash burn rate. As at September 2024, Boundless Bio had cash of US$167m and no debt. Looking at the last year, the company burnt through US$59m. So it had a cash runway of about 2.8 years from September 2024. Arguably, that's a prudent and sensible length of runway to have. Depicted below, you can see how its cash holdings have changed over time. Because Boundless Bio isn't currently generating revenue, we consider it an early-stage business. Nonetheless, we can still examine its cash burn trajectory as part of our assessment of its cash burn situation. Over the last year its cash burn actually increased by 30%, which suggests that management are increasing investment in future growth, but not too quickly. That's not necessarily a bad thing, but investors should be mindful of the fact that will shorten the cash runway. While the past is always worth studying, it is the future that matters most of all. For that reason, it makes a lot of sense to take a look at our analyst forecasts for the company. Given its cash burn trajectory, Boundless Bio shareholders may wish to consider how easily it could raise more cash, despite its solid cash runway. Generally speaking, a listed business can raise new cash through issuing shares or taking on debt. Commonly, a business will sell new shares in itself to raise cash and drive growth. We can compare a company's cash burn to its market capitalisation to get a sense for how many new shares a company would have to issue to fund one year's operations. Boundless Bio's cash burn of US$59m is about 154% of its US$39m market capitalisation. That suggests the company may have some funding difficulties, and we'd be very wary of the stock. Even though its cash burn relative to its market cap makes us a little nervous, we are compelled to mention that we thought Boundless Bio's cash runway was relatively promising. Even though we don't think it has a problem with its cash burn, the analysis we've done in this article does suggest that shareholders should give some careful thought to the potential cost of raising more money in the future. On another note, Boundless Bio has 5 warning signs (and 2 which don't sit too well with us) we think you should know about.
