BBI-940 novel Kinesin degrader program

The acceptance of the BBI-940 IND enables Boundless to advance the program into a first-in-human clinical trial for patients with metastatic breast cancer, KOMODO-1 (Kinesin Oral Molecular Degrader for Oncology-1), which is expected to initiate in the first half of 2026. Boundless’s novel Kinesin oral degrader program targets a previously undrugged kinesin involved in DNA segregation, including ecDNA segregation, during mitosis. BBI-940 has demonstrated potent anti-tumor activity across a range of cancer cell lines as well as in mouse xenograft models, including single-agent tumor regressions. The Company expects to deliver initial proof-of-concept clinical data within its cash runway timeline.

"The acceptance of the BBI-940 IND marks an important milestone for our first-in-class Kinesin oral degrader program, enabling us to advance this differentiated anti-cancer approach into clinical development," said Zachary Hornby, President and Chief Executive Officer of Boundless Bio. "In parallel, our portfolio prioritization and disciplined capital allocation sharpen our focus on BBI-940, maximizing our potential to deliver high-impact therapies for patients with high unmet need cancers."

POTENTIATE clinical trial of BBI-355 and BBI-825

Following a strategic portfolio review, Boundless Bio has elected to cease enrollment of the Phase 1/2 POTENTIATE trial evaluating the combination of BBI-355, its oral, selective CHK1 inhibitor and BBI-825, its oral, selective RNR inhibitor, in oncogene-amplified cancers. This decision reflects market considerations, clinical data, and the Company’s prioritization of programs with the greatest potential to deliver meaningful clinical impact and long-term value.

Financial Update

Based on the revised operating plan, the Company’s streamlined operations will extend its operating runway into the second half of 2028, through the anticipated initial clinical proof of concept readout for BBI-940.

Think Bioscience Raises $55M in Oversubscribed Series A

On January 20, 2026 Think Bioscience ("Think Bio"), a biotechnology company focused on unlocking elusive drug targets, reported it has raised $55M in an oversubscribed Series A. The round was led by Regeneron Ventures, Innovation Endeavors, and Janus Henderson Investors with participation from T.A. Springer, CE-Ventures, MBX Capital, and YK Bioventures. Returning investors include AV8 Ventures, CU Innovations, and Buff Gold Ventures.

Think Bioscience develops small molecule drugs for historically challenging drug targets by using synthetic biology to uncover novel footholds for medicinal chemistry (e.g., protein pockets). Their lead program targets mutants that cause Noonan syndrome, a genetic condition that affects approximately 1 in 2,500 births. Noonan patients experience life-threatening cardiac and lymphatic issues, short stature, cognitive impairment, and pain, among other chronic symptoms. There are no approved therapies that address the underlying biology of this disease.

"Our lead program has the potential to give a broad set of Noonan patients a better life," said Dr. Jerome Fox, co-founder and CEO at Think Bioscience. "We are grateful to our investors for supporting our vision to develop life-changing therapies."

Despite recent advances in computational chemistry, drug design remains exceedingly difficult. Most proteins in the human proteome are still considered undruggable—that is, they lack an obvious pocket for a drug to bind. Think Bio’s synthetic biology platform uses high-throughput functional surveys to find pockets that others miss and uses them to advance small molecules with biochemical activities previously deemed difficult, if not impossible, to achieve. They have extended their platform to a striking variety of targets, including transcription factors, protein phosphatases, kinases, proteases, and GTPases, while advancing a robust internal pipeline.

"This team is succeeding where others have failed. The lead program is the best example, but just one of many that the company is prosecuting. We are enthusiastic to double down." said Nick Olsen, Partner at Innovation Endeavors.

Propanc Biopharma Files New Provisional Patent Application for Methods of Producing Trypsinogen & Chymotrypsinogen with IP Australia

On January 20, 2026 Propanc Biopharma, Inc. (Nasdaq: PPCB) ("Propanc" or the "Company"), a biopharmaceutical company focused on developing novel treatments for chronic diseases, including recurrent and metastatic cancer, reported that a new provisional patent application has been filed for methods of producing trypinsogen and chymotrypsinogen with IP Australia. The patent application describes an optimized expression system to produce a world-first fully synthetic recombinant version of PRP, a long-term therapy for the treatment and prevention of metastatic cancer from solid tumors. According to Emergen Research, the global metastatic cancer market is projected to be worth $111 Billion by 2027.

A fully synthetic version of trypsinogen and chymotrypsinogen, called Rec-PRP, could have additional benefits to a global healthcare system that further capitalizes on a new therapeutic approach to treating cancer. For example, both proenzymes are synthesized by an in vivo (living organism) expression system, such as yeast cells, to produce proteins that could be maintained for long periods of time without suffering degradation in the absence of refrigeration. This is useful for a longer self-life as well as global distribution, particularly in warmer climates and developing regions where refrigeration is not available. Further, the program could produce large quantities of trypsinogen and chymotrypsinogen for commercial use that exhibits minimal variation between lots and without sourcing from animals. Therefore, management believes a fully synthetic recombinant version of PRP would have tremendous implications from a regulatory perspective, but also a practical, commercial benefit for global distribution.

"This provisional patent application is the third one filed over the past two months and will enhance our IP portfolio significantly as we enter national phase in countries worldwide for each of these patent applications," said Mr. James Nathanielsz, Propanc’s Chief Executive Officer. "We continue to execute our strategic plan building a platform technology that could be a world-first therapeutic approach to metastatic cancer from solid tumors, but without severe or serious side effects associated with standard treatments. Further, we are expanding our research into other therapeutic indications where there is a significant unmet medical need. We are building a strong and stable future for our Company and shareholders over the long term."

Phio Pharmaceuticals Announces Key Tumor Response Data from all Cohorts in Intratumoral PH-762 Dose Escalation Cutaneous Carcinoma Trial

On January 20, 2026 Phio Pharmaceuticals Corp. (NASDAQ: PHIO) is a clinical-stage siRNA biopharmaceutical company developing therapeutics using its proprietary INTASYL gene silencing technology to eliminate cancer. Phio reported a summary of the pathology results and safety outcomes across all cohorts in its Phase 1b dose escalation clinical trial with the INTASYL compound PH-762 for the treatment of skin cancer.

A total of 22 patients with cutaneous carcinomas completed treatment across five cohorts in the Phase 1b trial and underwent excision of the treated lesional site. Among the 20 patients with cSCC, 14 patients were determined to be pathologic responders, including 10 patients with complete response (100% clearance), 2 patients with major/near clear response (greater than 90% clearance), and 2 patients with partial response (greater than 50% clearance). A single patient with metastatic Merkel cell carcinoma had a partial response with greater than 50% clearance. Six cSCC patients and one melanoma patient had responses of less than 50%, however, none of the patients experienced a progression of the disease.

There were no dose-limiting toxicities or clinically relevant treatment-emergent adverse effects in any patients who received intratumoral PH-762 in this trial. PH-762 has been well tolerated in all enrolled patients in each of the five dose escalating cohorts, increasing drug concentration 20-fold from the first to the final cohort. Safety data through an extended follow-up period is expected to be reported in the second quarter of 2026.

"The pathology data is remarkable with an overall response rate of 70%, complemented by a favorable safety data. With this data in hand, we are now actively beginning the follow-on clinical trial design in the next step in the regulatory development pathway." said Robert Bitterman, CEO and Chairman of the Board, Phio Pharmaceuticals.

The Phase 1b clinical trial is designed to evaluate the safety and tolerability of neoadjuvant use of intratumoral PH-762 in Stages 1, 2 and 4 cSCC, Stage 4 melanoma, and Stage 4 Merkel cell carcinoma. Per the trial’s protocol, patients received four injections of PH-762 at weekly intervals and pathologic response was assessed 2 weeks following the final injection of PH-762.

MaaT Pharma Announces First Patient Randomized in IMMUNOLIFE Phase 2 Study Sponsored by Gustave Roussy, To Explore the Role of the Gut Microbiome To Overcome ICI Resistance in Advanced NSCLC Patients with Antibiotic-Induced Dysbiosis

On January 20, 2026 MaaT Pharma (EURONEXT: MAAT – the "Company"), a clinical-stage biotechnology company and a leader in the development of Microbiome Ecosystem TherapiesTM (MET) dedicated to enhancing survival for patients with cancer through immune modulation, reported that the first patient has been randomized in the IMMUNOLIFE Phase 2 clinical trial, a randomized multicenter study evaluating the potential of an oral pooled fecal microbiotherapy (MaaT033) in combination with Regeneron’s Cemiplimab (CB) in enhancing disease control rate versus best investigator’s choice (BIC) in patients with advanced non-small cell lung cancer (NSCLC) who have developed resistance to PD-1/PD-L1 blockade following antibiotic (ATB) exposure and who present ATB-induced gut dysbiosis.

The IMMUNOLIFE trial is evaluating MaaT033 in combination with CB vs BIC in 162 patients with advanced NSCLC who are refractory to immune checkpoint inhibitors (ICIs) and have received antibiotics. Patients are randomized (1:1) to receive either MaaT033 orally for one week prior to each cycle of CB (administered every 3 weeks for 6 months), followed by CB alone, or BIC. The primary objective is to assess whether the combination is associated with an improved disease control rate at 12 weeks compared to BIC. The study includes 14 centres in France, with patient enrolment of approximately 2 years and total CB treatment duration of 2 years. Primary results after 1-year follow-up post-treatment could be expected in late 2030. An interim futility analysis around H1 2027, after the 81st randomized patient.

"Gut dysbiosis is increasingly recognized as a risk factor for immunoresistance to immunotherapy. MaaT033 is designed to restore microbiome balance and may help improve patients’ response to treatment," said Lisa Derosa, MD, PhD at Gustave Roussy and coordinating investigator of the IMMUNOLIFE trial.

"We have built substantial evidence in our hemato-oncology programs that complex donor-derived products restore immune homeostasis in the context of pre-existing dysbiosis. This study represents an opportunity to further explore these findings in immuno-oncology in a well-defined patient population expected to show antibiotic-mediated dysbiosis," said Hervé Affagard, CEO and co-founder of MaaT Pharma.

This trial, sponsored by Gustave Roussy, is part of MaaT Pharma’s exploratory strategy launched in 2022, which also includes the PICASSO trial, a Phase 2a randomized controlled trial sponsored by AP-HP in Paris evaluating Xervyteg (MaaT013) in combination with ICIs, ipilimumab (Yervoy) and nivolumab (Opdivo) for patients with metastatic melanoma. The Company has been informed by PICASSO’s academic sponsor that topline results could not be available in Q4 2025 (as previously announced) and could now be expected in H1 2026. Overall, IMMUNOLIFE and PICASSO studies aim to contribute to the ongoing assessment of the Company’s research strategy, including indication, treatment line, and patient population. This will also inform on the clinical development of MaaT034, a co-cultured microbiome-based therapy and the Company’s next-generation drug candidate, designed to target large indications in solid tumors.

In parallel, data already generated and to be generated during the IMMUNOLIFE consortium will also fuel the Company’s AI platform and support the development of all the Company’s microbiome-based drug candidates.

The IMMUNOLIFE consortium includes leading academic institutions such as Gustave Roussy, INSERM, Paris Saclay University, INRAe, Hospital-University Institute (IHU) Méditerranée Infection and biotech companies. The consortium aims to address the challenge of primary resistance to ICI observed in advanced NSCLC patients following antibiotic exposure. The IMMUNOLIFE consortium receives funding from the French National Research Agency ("ANR-21-5 RHUS-0017 IMMUNOLIFE").

About MaaT033

MaaT033, a standardized, donor-derived, high-richness, high-diversity oral Microbiome Ecosystem TherapyTM containing anti-inflammatory ButycoreTM species, is currently being developed as an adjunctive therapy to improve overall survival in patients receiving HSCT and other cellular therapies. It aims to ensure optimal microbiota function and to address a larger patient population in a chronic setting. MaaT033 has been granted Orphan Drug Designation by the European Medicines Agency (EMA).

About MaaT034

MaaT034, currently in preclinical development, is a next-generation donor-independent full ecosystem synthetic microbiome therapy, dedicated to improving patient responses to immunotherapy in combination with Immune Checkpoint Inhibitors. Developed using the Company’s co-culturing proprietary MET-C platform, MaaT034 is optimized for large-scale production in oncology. Previous presented preclinical data showed that MaaT034 produced key metabolites, recognized as promoting gut barrier restoration and modulating immune responses, such as Short-Chain Fatty Acids (SCFA), secondary bile acids, and tryptophan derivatives. These data support the role of MaaT034 in gut barrier repair and in T cell reactivation either in combination with anti-PD1 or with anti-PD-L1. By enhancing gut barrier repair and modulating immune responses, MaaT034 is expected to complement the action of these immunotherapeutic agents, potentially improving their efficacy in treating solid tumors cancer.
