Context Therapeutics (NASDAQ:CNTX) has announced a portfolio prioritization and capital allocation strategy that is expected to extend its cash runway into late 2024.
Releasing its full-year 2022 financial statements, the Philadelphia-based women’s oncology company said the resulting changes include discontinuing the development of onapristone extended-release (ONA-XR) and focusing on the development of CTIM-76, its Claudin 6 (CLDN6) bispecific antibody clinical candidate.
“Given the challenging market conditions for emerging companies, the increasingly competitive landscape for breast cancer treatments, and recent study findings, we have decided to discontinue the development of ONA-XR,” Context CEO Martin Lehr said in a statement. “We are shifting our development focus to our compelling preclinical asset CTIM-76, a CLDN6 x CD3 bispecific antibody.”

“Additionally, we’re pleased that preclinical data regarding CTIM-76 will be presented at the upcoming American Association for Cancer Research (AACR) Annual Meeting 2023 in April and look forward to hosting an investor R&D webinar on the data following that presentation,” Lehr added.
Context noted that it ended the fourth quarter of 2022 with approximately $35.5 million in cash and cash equivalents. Based on its pipeline prioritization and related expense reduction, it said it expects to have sufficient financial resources to fund CTIM-76 beyond the filing of its Investigational New Drug (IND) application, which is expected to occur in the first quarter of 2024. The company does not anticipate any headcount reductions related to its portfolio prioritization, it added.
CTIM-76 program overview
Noting that there is a large unmet need for targeted therapies to treat solid tumors, Context explained that CTIM-76 is a CLDN6 x CD3 bispecific antibody that simultaneously binds to CLDN6-expressing cancer cells and CD3-expressing immune T cells.
In this manner, CTIM-76 functions as an immunotherapy that recruits a patient’s own immune system to attack cancer cells. CLDN6 is a developmental gene that is required for cell growth and is silenced after birth. Some cancers, including ovarian, lung, and testicular, reactivate this developmental gene to promote cancer cell growth and survival. Therefore, therapeutic inhibition of CLDN6 via CTIM-76 immunotherapy may restrict the growth of CLDN6-positive cancer cells.
Preclinical studies suggest the potential for convenient dosing and scalable manufacturing to address the significant number of patients who have CLDN6-positive disease.
ONA-XR recent study findings
In the ongoing Phase 2 OATH trial evaluating ONA-XR in combination with anastrozole, Context noted that elevated liver function tests (LFT) were identified in three patients, including in one patient who discontinued treatment, although none of the elevated LFTs was considered serious adverse events.
The company determined that significant incremental program costs and delays were likely to be required to analyze and potentially mitigate future LFT abnormalities.
Based upon the challenging market conditions for emerging companies, the increasingly competitive landscape for breast cancer treatments, recent study findings, and other factors, the company said it decided to cease development and explore strategic options for ONA-XR. As a result, it said it will no longer primarily focus on female cancers.
Strategy and recent pipeline updates:
- In March 2023, Context announced research regarding CTIM-76 will be presented on Monday, April 17 at 9am ET at the AACR Annual Meeting 2023, taking place April 14-19 in Orlando, Florida. Details about the presentations can be found here. Additionally on April 17 at 4:30pm ET, Context said it will host an investor R&D webinar with its management team and AACR presenter to discuss the presentation.

- In January 2023, Context announced a collaboration with Lonza, a global development and manufacturing partner to the pharma, biotech, and nutrition industries, to manufacture CTIM-76, the company’s clinical development candidate. CTIM-76 is a CLDN6 x CD3 T-cell engaging bispecific antibody targeting CLDN6-positive tumors.
- In November 2022, the company announced the selection of CTIM-76 as its lead clinical development candidate to target CLDN6-positive cancers, resulting from its research collaboration and licensing agreement with Integral Molecular. IND-enabling studies have been initiated and Context said it expects to submit an IND Application to support human clinical trials for CTIM-76 in 1Q 2024.
Full year 2022 financial results:
- Context ended 2022 with cash, cash equivalents, and restricted cash of $35.5 million, compared to $49.7 million on December 31, 2021.
- Its acquired in-process research and development expense was $500,000 for 2022, as compared to $3.1 million for the same period in 2021. The company said the 2022 expense was due to a development milestone achieved under its collaboration and license agreement with Integral Molecular for the development of CTIM-76, while the 2021 expense reflects the fair value of consideration paid/equity issued under that same agreement.
- Research and development (R&D) expenses were $7.1 million for 2022, as compared to $3.8 million for the same period in 2021. The increase in R&D expenses was primarily driven by higher contract manufacturing costs and clinical trial costs related to the ONA-XR program and increased preclinical costs for CTIM-76.
- General and administrative (G&A) expenses were $7.8 million for 2022, as compared to $3.6 million for the same period in 2021. The company said the increase in G&A expenses was primarily due to a higher employee compensation expense as a result of an increase in headcount and changes to compensation arrangements, as well as higher insurance and professional fees to support ongoing business operations and compliance obligations associated with being a publicly traded company.
- Context reported a net loss of $14.8 million for 2022, as compared to $10.5 million in 2021.
