"We have made significant progress recently across our oncology pipeline," said Kevin Lee, Ph.D., Chief Executive Officer of Bicycle Therapeutics. "We reported interim data for the Phase I portion of the Phase I/II trial in BT8009, showing an overall response rate, or ORR, of 50% in the 5mg/m2 weekly cohort in patients with urothelial cancer and an encouraging tolerability profile. We believe BT8009 has the potential to offer clinically meaningful differentiation compared to currently available therapies and we look forward to advancing the program once the dose escalation phase is complete. We also look forward to initiating the BT5528 Phase II expansion cohorts soon."
Dr. Lee continued: "Beyond our Bicycle Toxin Conjugates, or BTCs, we continue to be encouraged as we progress our Bicycle TICA programs forward, including BT7480, which is advancing in the dose escalation portion of the Phase I clinical trial. Underscoring our efforts is a strong balance sheet and we anticipate our cash and cash equivalents will provide financial runway through 2024."
First Quarter 2022 and Recent Highlights
Announced Interim BT8009 Phase I Clinical Trial Results at the 2022 American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting. In April 2022, Bicycle announced interim Phase I results from the Phase I/II trial of BT8009, a second-generation BTC targeting Nectin-4. As of March 7, 2022, thirty-seven patients have been dosed in the Phase I/II trial of BT8009. A total of twelve response evaluable urothelial cancer (UC) patients have been dosed in monotherapy cohorts of 2.5mg/m2 and 5.0mg/m2 weekly in the ongoing trial. Four response evaluable UC patients were dosed at 2.5mg/m2 weekly, with one patient observed to have tumor reductions constituting a confirmed partial response (PR) and two patients observed to have stable disease (SD). Eight response evaluable UC patients were dosed at 5.0mg/m2 weekly, with four patients observed to have a confirmed complete response (CR) or PR, including one patient with a CR and three patients with a PR, and two patients with SD, reflecting a 50% ORR and 75% disease control rate. The median duration of response has not yet been reached in either the 2.5 mg/m2 or 5.0mg/m2 cohort, with four of the five responders in these cohorts still on therapy after at least 24 weeks, and a tolerability profile that remains consistent with earlier results from this trial.
Exploration of additional doses and frequencies continues, and Bicycle intends to provide further updates this year.
Announced Updated Preclinical Data on SARS-CoV-2 Antivirals at the 2022 Microbiology Society Annual Meeting. Bicycle created a wide range of <10kDa molecules with high binding affinity to the SARS-CoV-2 spike protein and then tested them in partnership with researchers at the Medical Research Council Laboratory of Molecular Biology. They were shown to be highly active in vitro at preventing SARS-CoV-2 infection of human cells. These compounds were further tested in partnership with experts at the University of Liverpool and shown to be highly potent when administered in vivo to rodent models of SARS-CoV-2 infection. These molecules have also been shown to be active in vitro across many of the SARS-CoV-2 variant strains, including Alpha, Beta, Delta and Omicron.
Financial Results
Cash and cash equivalents were $407.4 million as of March 31, 2022, compared to $438.7 million as of December 31, 2021. The decrease in cash is primarily due to cash used in operating activities.
Research and development expenses were $14.3 million for the three months ended March 31, 2022, compared to $9.7 million for the three months ended March 31, 2021. The increase in expense of $4.6 million was primarily due to increased discovery and platform-related expenses, as well as increased personnel-related expenses, including $1.2 million of incremental non-cash share-based compensation expense.
General and administrative expenses were $17.0 million for the three months ended March 31, 2022, compared to $8.1 million for the three months ended March 31, 2021. The increase of $8.9 million for the three months ended March 31, 2022 as compared to the same period in the prior year was primarily due to $5.2 million incremental non-cash share-based compensation expense, personnel-related costs and increased professional and consulting costs.
Net loss was $27.6 million, or $(0.93) basic and diluted net loss per share, for the three months ended March 31, 2022, compared to net loss of $16.2 million, or $(0.73) basic and diluted net loss per share, for three months ended March 31, 2021.
