A Not for Profit Phase II Study to Evaluate Safety, Efficacy and Biomarkers secondary endpoints of Human Neural Stem cell intracerebroventricular transplantation in amyotrophic lateral sclerosis patients: a randomized, placebo controlled, triple blind study.
This is an approximate 24-months study (PHASE B) consisting, per patient, of a 30-day screening period, 12-month enrollment and follow up period. A preliminary 3+3 dose-escalation open-label phase (PHASE A) will be performed in order to test the toxicity of the two proposed cell doses. The study will be stopped when all the subjects included in the treatment period complete the study visits. The study uses an ATMP, for that reason all the patients follow up will be prosecuted long life.
Phase A: Open, monocentric safety, dose-finding study: The hNSCs will be produced by the UPTA (Unità Produttiva per Terapie Avanzate) of "Casa Sollievo della Sofferenza" according to GMP guidelines and injected using an Ommaya reservoir which will be removed immediately after the transplant procedure. The reservoir consists of an indwelling ventricular catheter with a dome-shaped collapsible silicone reservoir port positioned under the scalp. The distal end of the catheter is surgically positioned into the ipsilateral ventricle and connected to the reservoir. Six patients affected by ALS will be consecutively enrolled after pre- and screening visits. Thereafter, the first three patients will receive 20 million of hNSCs. If none of the three patients will present a serious adverse event classified as related to the study treatment, the dose level will be escalated up to 40 million of hNSCs for the next and last cohort of three patients. An Independent Data Safety Monitoring Board (DSMB) will oversee the safety of the Study Subjects on an ongoing basis, will review all safety data and issue a final recommendation at the end of this phase. Phase B: randomized, controlled vs placebo, in three arms, with two different doses of 20 and 40 *10\^6 cells transplanted using an Ommaya reservoir. The reservoir will be placed to all recruited patients in a first surgical session, after randomization half of the subjects will receive the drug product (further randomized for doses) and half the placebo. After three months, patients that already received cells will also be infused with placebo while the others will be randomized and transplanted with one of the two cell doses previously mentioned. This secondary randomization will be performed to provide experimental treatment to all patients and is not intended as a second stage of a cross-over study. In the second surgical session the Ommaya reservoir will be removed and patients will be monitored for 3 months after that.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.
Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Inoculation of 20\*10\^6 neural stem cells into the right lateral ventricle through a silicone catheter
Procedure: human Neural Stem Cells (hNSC)
Inoculation of 40\*10\^6 neural stem cells into the right lateral ventricle through a silicone catheter
Procedure: human Neural Stem Cells (hNSC)
Inoculation of saline (placebo) into the right lateral ventricle through a silicone catheter The reservoir will be placed to all recruited patients in a first surgical session, after randomization half of the subjects will receive the drug product (further randomized for doses) and half the placebo. After three months (period of time considered the minimum for a correct clinical evaluation that does not risk having to exclude patients treated with placebo from subsequent treatment with cells due to excessive physical decline), patients that already received cells will also be infused with placebo while the others will be randomized and transplanted with one of the two cell doses previously mentioned
Procedure: Saline (Placebo)
The patient is placed on a regular operating room table with or without rigid head fixation. Procedure will be performed whether under general anesthesia or sedation and local anesthesia. Image guidance will be registered using the frameless stereotactic AxiEM system. Image guidance will be used to perform ventricular cannulation with the catheter passed over an electromagnetic-tipped stylet, which is recognized and tracked by the navigation system. The correct placement of the catheter is verified by the egress of CSF. Finally the electromagnetic stylet will be removed and a Rickam reservoir connect to ventricular catheter. Operative time will be about 30 minute. A post-operative CT scan will be obtained in all patients to confirm the catheter position.

Safety of treatment
safety assessed with respect to the incidence of treatment-emergent AEs (TEAEs) and serious AEs (SAEs) over the whole study period
Time frame: From date of enrollment until 12 month.
Biological Endpoints
To evaluate the biological activity of hNSC treatment by measuring the levels of selected pharmacodynamics biomarkers in CSF and serum. Data will be statistically assessed for significance by either Student t test or analysis of variance as applicable. A p value of less than 0.05 will be considered statistically significant. Candidate markers include: lNf, GFAP, NF1, VEGF, Osteopontin, CXCL13, Cystatina, MCP-1 BDNF, YKL-40, IL-6, TNF-a, IL-17, TDP43 TAU In parallel to the clinical evaluation of hNSCs efficacy we will also develop patient-specific cell models in order to individuate molecular and cellular mechanisms supporting the putative therapeutic action of hNSCs treatment. These models will be derived from blood or skin cells of the patients recruited in the trial in order to produce iPS cells, then differentiated in NSCs. disease
Time frame: Samples for biological endpoints will be taken at treatment, 1, 3, and 6 months after treatment
