Allakos' Challenging Announcement on AK006 Trials
In a significant development for Allakos Inc., the company disclosed the results of its Phase 1 trial of AK006 for treating chronic spontaneous urticaria (CSU), revealing that the treatment did not show expected therapeutic activity. This announcement has prompted the company to make the tough decision to discontinue the drug's further development.
Chin Lee, M.D., M.P.H., the Chief Medical Officer at Allakos, expressed the company’s disappointment given that while AK006 was generally well tolerated, the anticipated clinical benefits were not realized in patients suffering from CSU. The team at Allakos remains grateful for the contributions of patients, clinical trial investigators, and coordinators throughout the trial process.
Insights from the Phase 1 Clinical Trial
The Phase 1 study involved 34 adults with moderate to severe CSU who were refractory to antihistamine treatments, with some having prior exposure to omalizumab. Participants received either 720 mg of intravenous AK006 or a placebo once every four weeks. The primary aim was to evaluate the treatment's safety and tolerability, while exploring efficacy primarily through the Urticaria Activity Score (UAS)-7 at the 14-week mark.
Trial Results and Efficacy Overview
The results indicated that while the baseline UAS-7 for the AK006 group was recorded at 34.4, the placebo group started at 30.5. After treatment, a mean change in UAS-7 of -8.2 in the AK006 group was seen compared to -12.4 in the placebo group. Notably, only 9% of both groups achieved a complete response as indicated by a UAS-7 score of 0.
Safety Profile Assessment
Despite the disappointing efficacy results, AK006 demonstrated a favorable safety profile with no serious adverse events reported. Common adverse effects included mild to moderate incidences of headache and infusion-related reactions. There was an equal distribution of COVID-19 occurrences among subjects, which were also mild in severity.
Company Restructuring Plans
In light of these trial results, Allakos announced a significant restructuring initiative, which includes a 75% reduction in its workforce. The company aims to retain about 15 employees to manage regulatory compliance and to oversee the winding-down of the study.
Financial Guidance Moving Forward
As part of its transitioning strategy, Allakos finished the previous quarter with around $81 million in cash and investments. The restructuring costs tied to discontinuing AK006 development are estimated to range from $34 million to $38 million, predominantly during the early months of the next year. Post-restructuring, Allakos anticipates maintaining approximately $35 million to $40 million in cash reserves by mid-year.
Future Communication Plans
To address investor concerns and provide further insights, Allakos management will host a conference call and webcast to discuss these developments and answer any inquiries. This forum will allow stakeholders to gain a clearer understanding of the company’s direction following the discontinuation of AK006.
