Corporate Updates and Recent Events
Company Strategy
Outlined strategic priorities at the company’s first Research & Development (R&D) Day in December:
Execute plan to become a leader in next-generation solid tumor therapeutics and combinations, which includes:
Initiating the Phase 2/3 Duravelo-2 registrational trial for BT8009 in metastatic urothelial cancer (mUC) in 1Q 2024. The trial is now active and recruiting patients.
Conducting further clinical studies to assess BT8009, BT7480 and BT5528 in emerging tumors of interest, with data from these studies expected in 2H 2024.
Expand opportunities in oncology, which includes:
Advancing the company’s next generation of Bicycle Toxin Conjugates (BTCs). The company plans to select a BTC clinical candidate using next-generation technology in 2H 2024.
Validating the company’s Bicycle Radio Conjugates (BRC) pipeline and partner for success, with updates expected from its wholly owned BRC program by mid-2024.
Advancing the company’s Bicycle Tumor-Targeted Immune Cell Agonist (Bicycle TICA) immune-oncology pipeline through innovative partnerships.
Explore platform potential beyond oncology, which includes:
Continuing the company’s strong track record of collaboration.
Partnering with leading academic, government and life sciences organizations.
Nectin-4 Portfolio
BT8009 is a BTC targeting Nectin-4 designed to overcome the significant toxicity associated with other toxin conjugate approaches.
Announced Updated BT8009 Clinical Data from the Ongoing Phase 1/2 Duravelo-1 Study Involving Heavily Pre-Treated Patients. BT8009 showed: :
A promising response profile with a 38% objective response rate (ORR) in 26 patients with mUC receiving 5 mg/m2 weekly and who had not been treated with enfortumab vedotin (EV-naïve), and a median duration of response (mDOR) of 11.1 months in 10 patients with five responders still on therapy.
Encouraging initial data in other cancers such as ovarian, triple-negative breast (TNBC) and non-small cell lung (NSCLC) that support further expansion beyond mUC.
An emerging differentiated safety profile seen in 113 patients with various types of cancer receiving 5 mg/m2 weekly, with treatment-related adverse events being primarily low in frequency and severity.
In 34 EV-naïve mUC patients, treatment-related adverse events and adverse events of interest were also low, similar to the 5 mg/m2 weekly total safety study population. Notably, there were zero cases of severe (≥Grade 3) ocular disorders, peripheral neuropathy or skin reactions that are commonly observed with antibody drug conjugate (ADC) therapies.
In seven heavily pre-treated mUC patients receiving BT8009 5 mg/m2 weekly in combination with pembrolizumab, an acceptable tolerability profile was observed with limited severe treatment-related adverse events, including zero cases of severe (≥Grade 3) ocular disorders, peripheral neuropathy or skin reactions that are commonly observed with ADC therapies.
In 2H 2024, the company plans to complete the Phase 1/2 Duravelo-1 open-label study across multiple cancers and report data from the following cohorts:
° BT8009 5 mg/m2 weekly in late-line, EV-naive mUCBT8009 5 mg/m2 weekly in late-line, EV-naive mUC;
° Ovarian, TNBC and NSCLC cancer; and
° BT8009 5 mg/m2 weekly in combination with pembrolizumab in first-line mUC.
BT8009 Selected to Participate in U.S. Food and Drug Administration (FDA) Program to Expedite Commercial Manufacturing Readiness. In October, Bicycle Therapeutics announced the FDA selected BT8009 to participate in the FDA’s new Chemistry, Manufacturing, and Controls (CMC) Development and Readiness Pilot (CDRP) Program, which was created to facilitate CMC development for therapies with expedited clinical development timeframes, based on the anticipated clinical benefits of earlier patient access to the therapy. BT8009 is one of up to nine products selected for the inaugural cohort of the CDRP Program.
BT7480 is a Bicycle TICA targeting Nectin-4 and agonizing CD137 designed to overcome immune agonist toxicities and activate the immune system in Nectin-4 expressing tumors.
Announced Clinical Data from the Phase 1 Clinical Trial. BT7480 showed:
In 33 patients assigned to receive one of nine different doses of BT7480, an emerging differentiated safety and tolerability profile with a low number of severe adverse events. The majority of the patients studied had tumors that expressed Nectin-4 and CD137.
Two unconfirmed partial responses in heavily pre-treated patients with cervical cancer.
Three prolonged stable disease (≥7 months) in NSCLC and anal cancer.
The company will continue to define the recommended Phase 2 dose (or maximum dose) and dose range for BT7480, with a view to enroll combination cohorts with checkpoint inhibitors in 2024. These data will inform the design of a Phase 2 trial that could support potential accelerated approval of BT7480.
Ephrin-A2 (EphA2) Portfolio
BT5528 is a BTC targeting EphA2, a historically undruggable target, and is designed to overcome the significant toxicity associated with other toxin conjugate approaches.
Announced Clinical Data from Ongoing Phase 1/2 Clinical Trial Enrolling Patients with Various Solid Tumors. BT5528 showed:
In 109 patients, an acceptable emerging tolerability profile with few severe adverse events. Importantly, unlike other EphA2-targeted agents, no bleeding events were observed in patients treated with BT5528 at any dose.
Encouraging early activity in mUC with a 39% ORR in 18 patients receiving 6.5 mg/m2, 8.5 mg/m2 or 10 mg/m2 every other week, and an mDOR of four months in seven patients with one responder still on therapy. This includes six partial responses and one unconfirmed response.
Encouraging emerging data in other cancers such as ovarian, gastric/upper gastrointestinal and head and neck that are informing the dose optimization strategy and further development.
The company commenced further cohorts in mUC and ovarian cancer to test 5 mg/m2 weekly, which will inform decisions about dose optimization, potential drug combinations and expansion into other tumor types. Data from these cohorts are expected to be available in the second half of 2024.
