Key Financial Metrics and Liquidity
The filing does not provide revenue, profit or loss, cash flow, margins, debt, liquidity, or other financial metrics. It states that the sufficiency of the company’s cash resources is among the risks affecting its development programs.
Material Changes Versus the Prior Comparable Period
- Instil voluntarily paused enrollment in the Phase 2 DELTA-1 trial of ITIL-168 in patients with advanced melanoma after a recent decline in the rate of successful ITIL-168 manufacturing.
- Some patients could not be dosed because their individual ITIL-168 products were not successfully manufactured.
- Enrollment was also voluntarily paused in the Phase 1 DELTA-2 trial of ITIL-168 combined with pembrolizumab in patients with solid tumors.
- Enrollment in the Phase 1 ITIL-306 trial was voluntarily paused as part of the broader manufacturing analysis, although no manufacturing failures had been observed in that trial to date.
Guidance, Outlook, Risks, and Unusual Items
No regulatory agency, including the FDA, had placed a clinical hold on any of the company’s trials. A pre-specified safety analysis of DELTA-1 participants who received ITIL-168 identified no unexpected safety issues.
Instil commenced an end-to-end review of its manufacturing processes and intends to implement corrective actions to improve manufacturing success rates before resuming the studies. Management expected to provide an update on the manufacturing analysis by early first quarter 2023.
Key risks include manufacturing and testing of cell therapy products, delays or failures in clinical trial enrollment and completion, uncertain clinical efficacy and regulatory approval, the effects of COVID-19, the costly and time-consuming development process, and the adequacy of available cash resources. The company cautioned that forward-looking statements are subject to material risks and uncertainties and are not guarantees of future performance.
