• Presented Potent Anti-Tumor Activity of a Lead-212 Labelled MT1-MMP Targeting Bicycle Radionuclide Conjugate™ at TIDES 2023. In May 2023, Bicycle presented preclinical results from a preclinical research collaboration with OranoMed. In these studies, Pb-BCY20603, a prototype BRC™ that binds with high affinity to the tumor antigen MT1-MMP and carries a chelate of lead-212, showed potent anti-tumor activity in rodent tumor xenograft studies and achieved complete tumor regressions after 3 dosing cycles of 10 µCi, given two weeks apart. Median survival was increased for each dosing group with 90% survival observed for the 3 cycles of 10 μCi, treatment at the end of the 100-day study.

• Announced Multiple Strategic Collaborations for Developing BRCs for Potential Oncology Targets
  • Strategic Collaboration with Bayer. In May 2023, Bicycle announced that it has entered into a strategic collaboration agreement with Bayer to discover, develop, manufacture, and commercialize BRCs for multiple agreed upon oncology targets. Bicycle will use its proprietary phage platform to develop bicyclic peptides, while Bayer will be responsible for, and fully fund, all further preclinical and clinical development, manufacturing, and commercialization activities. Bicycle received a $45 million upfront payment in July 2023 and, with potential development and commercial-based milestone fees, payments under the collaboration to Bicycle could total up to $1.7 billion. Bicycle will also be eligible to receive tiered royalties on Bicycle-based medicines commercialized by Bayer.
  • Expanded Collaboration with the German Cancer Research Center. In May 2023, Bicycle announced the extension of a collaboration with the German Cancer Research Center (DKFZ) to develop and discover BRCs for potential oncology targets. This enhanced relationship will provide a more continuous and purpose-driven commitment towards advancing Bicycle’s wholly owned BRC candidates. Bicycle intends to commence initial testing of its wholly owned BRCs in patients during 2024.
  • Strategic Collaboration with Novartis. In March 2023, Bicycle announced a strategic collaboration with Novartis to collaborate on the discovery, development and commercialization of BRCs for multiple agreed upon oncology targets. Bicycle will utilize its proprietary phage platform to discover Bicycles to be developed into BRCs. Novartis will be responsible for and fund further development, manufacture and commercialization of the BRCs. Under the collaboration, Bicycle received a $50 million upfront payment in April 2023 and is eligible for development and commercial-based milestone payments totaling up to $1.7 billion. Bicycle will also be eligible to receive tiered royalties on Bicycle-based medicines commercialized by Novartis.

Financial Results

• Cash and cash equivalents were $340.4 million as of June 30, 2023, compared to $339.2 million as of December 31, 2022. The increase in cash and cash equivalents is primarily due to $50.0 million received from our collaboration agreement with Novartis and $14.8 million of net proceeds from our ATM offering program, offset by cash used in operating activities. Our cash and cash equivalents at June 30, 2023 do not include the upfront payment from Bayer or proceeds from our public offering received in July 2023. Additionally in July, the company strengthened its balance sheet with gross proceeds of $230.0 million, or net proceeds of approximately $215.5 million, from the July 2023 public offering.

• Research and development expenses were $39.7 million for the three months ended June 30, 2023, compared to $19.9 million for the three months ended June 30, 2022. The increase in expense of $19.9 million was primarily due to increased clinical program expenses for BT8009, BT7480 development expenses, and other discovery and platform related expenses, as well as increased personnel-related expenses, including incremental non-cash share-based compensation expense of $1.3 million, offset by incremental UK research and development incentives.

• General and administrative expenses were $14.8 million for the three months ended June 30, 2023, compared to $11.8 million for the three months ended June 30, 2022. The increase of $3.0 million for the three months ended June 30, 2023 as compared to the same period in the prior year was primarily due to an increase in professional and consulting fees, as well as an increase in personnel-related expenses, including incremental non-cash share-based compensation expense of $1.2 million, offset by a favorable impact of foreign exchange rates.

• Net loss was $42.6 million, or $(1.41) basic and diluted net loss per share, for the three months ended June 30, 2023, compared to net loss of $26.8 million, or $(0.90) basic and diluted net loss per share, for three months ended June 30, 2022.
