A Trial of "APL-9796'' in Adults With Pulmonary Hypertension

Q: Who can participate in NCT06846554?

Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.

Q: How do I contact the trial site for NCT06846554?

Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.

Q: Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.

A Phase 2, Multicentre, Open-Label Trial to Evaluate APL-9796 in Adult Participants With Pulmonary Hypertension (ViTAL-PH)

A Trial of "APL-9796'' in Adults With Pulmonary Hypertension (NCT06846554) is a Phase 2 interventional studying Pulmonary Arterial Hypertension, sponsored by Apollo Therapeutics Ltd. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

The AP13CP02 study is a phase 2, open-label, dose escalation trial to determine how safe and tolerable multiple subcutaneous (SC) injections of APL-9796 are for patients with PH. The study will also assess how effective APL-9796 could be for treating patients with PH and whether the body produces antibodies working against APL-9796. The trial will be conducted in two parts: * Part A: Up to 36 adults with WHO Group 1 Pulmonary arterial hypertension (PAH). * Part B (optional): Up to 12 adults with WHO Group 3 - PH associated with ILD (PH-ILD).

What Stage of Research Is This?

Phase 2 trials evaluate whether a treatment actually works against Pulmonary Arterial Hypertension and continue monitoring side effects. Phase 2 enrolls larger groups (typically 100–300 patients) and produces the first real efficacy signal. A successful Phase 2 readout is what unlocks the much larger Phase 3 confirmatory trials needed for FDA approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

With a target enrollment of 48 participants, this is a small study — typical of early-phase research, rare-disease trials, or pilot studies designed to generate preliminary signal before a larger study is launched.

Who May Be Eligible (Plain English)

Who May Qualify: 1. Participant must be 18 to 80 years of age inclusive 2. Participants who are diagnosed with pulmonary hypertension via right heart catheterisation (RHC), documented at any time prior to Screening. 3. WHO Functional Class II or III 4. Participant has the CardioMEMS PA Sensor implanted. Who Should NOT Join This Trial: 1. Hospital admission related to PH within 3 months prior to Screening. 2. Major surgical procedure within 3 months prior to Screening, unless participant is assessed as completely recovered by the Investigator 3. Diagnosis of PH due to human weakened immune system virus, portal hypertension, schistosomiasis, or uncorrected congenital heart disease 4. History of left-sided heart disease and/or clinically significant cardiac disease 5. History of uncontrolled systemic hypertension 6. eGFR ≤30 ml/min/1.73m2 7. Life expectancy of \< 12 months, as assessed by the Investigator 8. Diagnosed with a malignancy within 5 years of enrolment 9. Contraindications to protocol-required imaging (MRI), diagnostic, or sampling methods Always talk to your doctor about whether this trial is right for you.
