Item 7.01 Regulation FD Disclosure.
On September 28, 2026, CAMP4 Therapeutics Corporation (the “Company”) held an Analyst Day meeting regarding its planned Phase 1/2 ASCEND clinical trial of CMP-002 in SYNGAP1-related disorder (the “ASCEND clinical trial”) and its pipeline of product candidates. A copy of the data presentation used in connection with the Analyst Day meeting is furnished as Exhibit 99.1 to this Current Report on Form 8-K.

In addition, on September 28, 2026, the Company updated its corporate presentation, which is available on the “Investors” section of the Company’s website at https://investors.camp4tx.com. This presentation is also furnished as Exhibit 99.2 to this Current Report on Form 8-K.

The information in this report is furnished pursuant to Item 7.01, including Exhibits 99.1 and 99.2 attached hereto, and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such filing.

Item 8.01 Other Events.

On September 28, 2026, the Company held an Analyst Day meeting at which it provided the following updates regarding the ASCEND clinical trial and the Company’s pipeline of product candidates.

ASCEND Clinical Trial

The ASCEND clinical trial is a Phase 1/2, randomized, double-blind, placebo-controlled, multiple ascending dose (“MAD”) study. Participants will be randomized 3:1 to receive intrathecal administration of CMP-002 or a sham procedure consisting of a pinprick. The clinical trial includes three MAD cohorts with a minimum of eight participants each, followed by an open-label extension study. The Company believes that the dose levels to be administered in each of the three cohorts are within the expected therapeutic range based on pharmacokinetic and pharmacodynamic modeling of its preclinical data. The primary goals of the clinical trial include demonstrating safety and tolerability, characterizing pharmacokinetics and selecting an optimal biological dose, and identifying relevant endpoints applicable to patients with SYNGAP-1-related disorder (“SRD”) for subsequent study of CMP-002.

The ASCEND clinical trial is designed to enroll participants aged 2 to less than 18 years with genetically confirmed SRD. Key inclusion criteria include a clinical diagnosis of SRD with genetic confirmation of a protein-truncating mutation in SYNGAP1 exons 5-19, a haploinsufficiency phenotype characterized by intellectual disability, inability to speak in full phrases, sleep disturbance, refractory epilepsy (defined as daily seizures despite at least one ongoing anti-seizure medication) and a prior trial of at least two anti-seizure medications, and a stable anti-seizure medication regimen prior to baseline. Key exclusion criteria include non-truncating SYNGAP1 variants (including missense variants, microdeletions, variants located in exons 1-4 or variants of uncertain significance), a history of central nervous system disease unrelated to SRD, spinal abnormalities or other conditions that would make intrathecal dosing unsafe, and clinically significant laboratory abnormalities.

The ASCEND clinical trial is designed to include a 28-day screening period, a baseline assessment period of at least four weeks, a treatment period during which three doses will be administered over approximately three months, and a post-treatment follow-up period with assessments at multiple timepoints over approximately six months. Total participant time in the clinical trial is expected to be approximately 10 months. The clinical trial includes daily seizure diary completion,



actigraphy monitoring, safety and side effect review and functional assessments across multiple domains throughout the clinical trial.

The ASCEND clinical trial will also assess exploratory endpoints across six key domains of SYNGAP1-related disorder: seizures, sleep, motor function and gait, communication, behavior, and development and cognition. Seizure and sleep assessments will include 24-hour video-electroencephalography (“EEG”), seizure diaries, the Seizure-Related Impact Assessment Scale, actigraphy, and the Children’s Sleep Habits Questionnaire. The clinical trial will utilize five validated scales to assess behavior, development, communication, and motor function: the Bayley Scales of Infant and Toddler Development, 4th Edition; the Vineland Adaptive Behavior Scales, 3rd Edition; the Aberrant Behavior Checklist, 2nd Edition; the Observer-Reported Communication Ability Measure; and the Gross Motor Function Measure. EEG-based measures will be utilized to assess multiple parameters.

The ASCEND clinical trial is planned to be conducted at more than 11 clinical trial sites across at least nine countries. Sites in the United Kingdom, Australia and Argentina have been approved by the relevant regulatory authorities. Sites in the European Union are under review by applicable regulatory and ethics authorities.

The Company expects to dose the first patient in the ASCEND clinical trial by the end of 2026. The Company is targeting a topline data readout from the ASCEND clinical trial in the first half of 2028.

Pipeline Updates

In addition, the Company provided an update on its broader pipeline of product candidates. The Company is advancing a preclinical program targeting SHANK3 for the treatment of Phelan-McDermid Syndrome, a neurodevelopmental disorder characterized by autism, developmental delay, intellectual disability, motor impairment and milestone regression, for which there are no approved disease-modifying treatments. The Company estimates that there are more than 45,000 patients with Phelan-McDermid Syndrome in the United States. The Company expects to designate a development candidate in the SHANK3 program in 2027. The Company also disclosed that it is evaluating programs for two additional early-stage haploinsufficient diseases of the central nervous system.
