About this study
Official title: Efficacy and Safety of Rapamycin Therapy for Patients With Activated Phosphoinositide 3-Kinase δ Syndrome
The purpose of this proposed research is to evaluate the efficacy and safety of the rapamycin therapy in patients with activated phosphoinositide 3-kinase δ syndrome (APDS).
Read the detailed description
Activated phosphoinositide 3-kinase δ syndrome (APDS) is a recently described autosomal dominant primary immunodeficiency (PID), caused by the mutations in PIK3CD gene. The manifestations of APDS mainly include recurrent respiratory tract infections, persistent Epstein-Barr virus (EBV)/ cytomegalovirus (CMV)infections, lymphadenopathy, splenomegaly, CD4+T cells lymphopenia, and hyper-IgM syndrome. PIK3CD encodes p110δ, the catalytic subunit of phosphatidylinositol 3-kinase (PI3K) which mainly expresses in leukocytes, being critical for their proliferation, activation and survival. Gain-of-function (GOF) PIK3CD mutations lead to PI3Kδ hyperactivity, with the downstream mediators Akt and mammilian target of rapamycin (mTOR) hyperphosphorylated. Patient-derived lymphocytes had increased levels of phosphatidylinositol 3,4,5-trisphosphate and phosphorylated AKT protein. Hyperactivation of mTOR increases phosphorylation of kinases and increased glycolysis that results in enhanced proliferation and senescence of terminally differentiated CD8+ Tcell populations.
The optimal treatment for these APDS patients is not yet determined; however, there are many kinds of therapeutic approaches (anti-infection prophylaxis, immunoglobulin replacement, conventional immunosuppressants, PI3K/mTOR inhibitors and hematopoietic stem cell transplantation). The APDS patients frequently receive treatment with immunoglobulin replacement and antibiotics. Hematopoietic stem cell transplantation (HSCT) has been currently curative in APDS patients; however, longer-term follow-up to determine the degree of donor chimerism and efficacy is required. There are several subjects without a prompt suitable matched donor or for whom the critical disease conditions force to postpone HSCT.The mammalian/mechanistic target of inhibitor rapamycin was reported to improve circulating T-cell profiles. Individual patients in previous studies experienced a decrease in nonneoplastic lymphoproliferation while taking rapamycin.
The investigators in this study hope to evaluate the efficacy and safety of rapamycin in the treatment for carefully selected patients with APDS.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Rapamycin in people with Activated PI3K-delta Syndrome and Immunodeficiency Primary, run by Children's Hospital of Fudan University at 2 sites in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 9 Jul 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Frequency of Recurrent Infections (time frame: 5 years). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03383380, which also lists 6 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Jul 2024.
