Protocol Title: 
A Phase 2 Safety Study of L1-79 in the Treatment of Autism 
 
• Study Phase: 2 
 
• Study Design: This study has a dose escalating cohort design. Treatment arms 
consist of L1-79 at doses of 100 mg t.i.d (or placebo), or 200 mg t.i.d., (or 
placebo).  Pharmacokinetics will be assessed in initial cohorts of 5 patients for 
each dose group followed by a double blinded, placebo-controlled assessment of 
PK/PD and safety in a cohort of 15 patients randomized 2:1 active to placebo.  
Groups 1& 2 below can start simultaneously.  While the FDA is reviewing the 
data from Group 1, Groups 2 and the placebo patients randomized with Group 2 
will be ongoing.  All 5 subjects assigned to Group 1 (100 mg L1-79) must have 
completed the PK portion of the study with results analyzed and accepted by the 
FDA before subjects in Groups 3-5 can begin treatment. 
 
• Sample Size: N=40

INTRODUCTION AND RATIONALE 
L1-79 is being developed for the treatment of autism.  Dr. F Peter Halas holds IND 
128673 and is also one of the Principal Investigators.  Yamo Pharmaceuticals LLC, a part 
of Hoffman Technologies is providing support and L1-79 for the study. 
 
L1-79 is racemic α-methyl-para-tyrosine (AMPT).  This molecule was developed by 
Merck in the 1950’s & 60’s.  The L-isomer was approved in 1979 as a presurgical 
treatment for the excision of pheochromocytoma tumors under the tradename Demser®.  
Because pheochromocytomas produce high levels of catecholamines, surgical 
manipulation of these masses liberates substantial concentrations of epinephrine and 
norepinephrine resulting in adverse cardiovascular events.  Demser inhibits the first, and 
rate limiting, step in catecholamine synthesis, the conversion of tyrosine to 
dihydroxyphenylalanine (DOPA), and thus reduces the synthesis of dopamine (DA), 
norepinephrine (NE), and epinephrine (E).  This inhibition has the effect of reducing 
tissue catecholamine levels making the tumor more amenable to extirpation without 
adverse consequences.  Demser has also been approved for the treatment of subjects with 
pheochromocytoma for whom surgical excision is not an option to reduce the 
cardiovascular consequences of elevated levels of circulating catecholamines. 
 
Catecholaminergic functions in the CNS and in the gut have been implicated as 
underlying the symptoms of autism.  In the brain, dopaminergic systems have been 
shown to underlie systems that mediate pleasure, irritability, agitation, reward, and other 
symptoms that characterize autism.  In the gut and mesentery, catecholaminergic systems 
are known to modulate digestion, and may underlie the digestive and dietary 
abnormalities associated with autism. 
 
L1-79 has been used in a 30 patient phase 1 trial as one agent in the polytherapy named 
SM-88 (previously called SMK) (J Clin Oncol 31, 2013 suppl; abstr e22095).  L1-79 was 
used at a dosage of 280 mg/d, along with daily 3-Amino-2-hydroxy-4-phenylbuteryl]-L-
leucine (55 µg/d), phenytoin (32 mg/d), melanin (50 µg/d), and the melanin inducer 
melanotan II (10 µg/d) (IND #127977).  In this regimen, L1-79 was administered to stage 
4 metastatic cancer patients with a variety of tumor types including breast, prostate, 
pancreas, colon, lung, appendix, and others, who had failed all available therapeutic 
regimens.  
 
An exploratory study intended to observe the effects of L1-79, when administered to 
patients with autism spectrum disease, was initiated at two sites in New Jersey.   L1-79 
was given to 10 patients to date on a t.i.d. schedule.  Preliminary results indicated that 
L1-79 reduced the core deficits in a number of subjects, with the racemic form of the 
drug being more effective than either of the two stereoisomers alone.  Utilizing the 
Aberrant Behavior Checklist – Community (ABC-C), Autism Diagnostic Observation 
Scale (ADOS), and Connor Parent Rating Scale (CPRS), improvements in all of the core 
symptoms of autism have been observed to occur quickly in subjects of both sexes and

ranging in age from 2½ to 24 years of age, with continual improvement with treatment 
over time. 
 
Most of the clinical experience with L1-79 for the treatment of autism is with doses of 
100-300 mg t.i.d.. This study seeks to quantify the safety and efficacy of L1-79 
administered t.i.d. in doses of 100 or 200 mg to subjects with a diagnosis of autism based 
upon their ADOS results in a prospectively randomized and double-blind manner.

STUDY PURPOSE AND OBJECTIVES 
2.1 
Purpose 
The purpose of this clinical trial study is to determine whether L1-79 is a well-tolerated 
and clinically useful agent for the treatment of ASD, and to assess the pharmacokinetics 
and pharmacodynamics of 4 weeks of t.i.d. dosing with L1-79. 
2.2 
Study Objectives 
2.2.1 PRIMARY OBJECTIVE 
To document the safety of L1-79 by assessing adverse events, electrocardiographic and 
physical examination measures, including vital signs and laboratory parameters at 2 
different dose levels of L1-79. 
2.2.2 SECONDARY OBJECTIVES 
To document the PK and PD of L1-79 in a repeated dosing clinical situation, and to 
assess any change from baseline in the core symptoms of autism and associated behaviors 
using various standardized, validated ASD assessment instruments, and by comparing the 
results of subjects randomized to receive 1 of 3 different dosage levels of l-79 against 
placebo in a double-blind fashion.  Also, changes in the ADOS core, including the 
severity scale, and the Clinical Global Impressions scale (CGI), including severity and 
improvement subscales will be assessed.

DESIGN AND METHODS  
3.1 
Study Design   
This is a five-arm design that incorporates 2 open label groups whose doses are known 
for the purpose of understanding PK/PD and to determine if there are any EKG changes 
associated with the administration of L1-79, and a 3-group prospectively randomized, 
double-blind, trial of L1-79 at 2 dosage levels versus placebo.   
 
Two dosages of L1-79 will be tested in this study: 100 mg t.i.d. and 200 mg t.i.d.  The 
investigators in this study have the most experience with these two dosages during 
exploratory use of L1-79 described above.  In preliminary observations in a number of 
patients between the ages of 2.75 and 24 years of age doses between 90 to 400 mg t.i.d. 
were well tolerated, and no evidence was found that suggests a need for weight based 
dosing.  These findings were presented to the FDA.  
 
The first cohort of 20 patients to be enrolled will all receive L1-79 100 mg t.i.d., and will 
be comprised of 3 groups of patients.  The first 100 mg group will differ from the others 
in that they will get blood samples drawn for PK analysis and EKGs will be taken.  The 
safety and PK data from this group will be submitted for FDA review and acceptance 
before the 200 mg t.i.d. cohort will be enrolled.  The remaining 15 patients in this cohort 
will be randomized to receive either L1-79 100 mg t.i.d. or placebo on a 2:1 basis (2 L1-
79 patients for each placebo patient).  While the FDA is reviewing the data from the first 
5 patients all 100 mg t.i.d. patients will continue to be treated. 
 
The second cohort is identical to the first.  The initial 5 patients to be enrolled will differ 
from the others in that they will get blood samples drawn for PK analysis and EKGs will 
be taken.  The safety and PK data from this group will be submitted for FDA review and 
acceptance.  The remaining 15 patients in this cohort will be randomized to receive either 
L1-79 200 mg t.i.d. or placebo on a 2:1 basis (2 L1-79 patients for each placebo patient).  
While the FDA is reviewing the data from the first 5 patients all enrolled patients will 
continue to be treated 
 
Adolescents, between the ages of 13 and 21 years, with ASD who meet the 
entry/exclusion criteria, and with sufficiently high function to complete this study in the 
opinion of the Investigator, will be treated daily for 4 weeks.  Standard psychometric tests 
will be utilized in the clinic and at home to ascertain affect and performance in order to 
assess changes in the symptoms and the diagnosis of autism. 
 
Enrollment will be limited to male patients pending FDA approval and the completion of 
reproductive toxicology studies.

treatment arms (100 mg or 200 mg L1-79 t.i.d.  The first 5 patients in each Treatment 
Arm enrolled and will be required to provide EKG tracings and blood specimen(s) for 
determination of pharmacokinetics for the estimation of exposure.  Once this lead-in 
group has completed one-week of treatment and EKG tracings are not abnormal and 
blood specimen(s) for the determination of L1-79 concentrations have been analyzed, and 
a report on the PK and safety data from this group has been reviewed by the FDA and 
permission from the FDA is obtained to escalate the dose, then, 20 additional patients 
will be enrolled and treated in the same manner as the 100 mg t.i.d. group, such that 5 
open label patients will be treated as described above and 15 patients will be randomized 
2:1 to receive 200 mg L1-79 t.i.d.

STUDY PROCEDURES 
5.1 
Consent and Assignment of Subjects to Treatment 
Each patient or their representative must sign a copy of the informed consent document.  
The patient will be asked to provide assent to participate in the study (Appendix B).  The 
study staff will explain this form in non-technical language, in detail, and will answer all 
questions that a patient might ask.  Staff will explain to all subjects that subjects who 
qualify for entry into this trial will receive an experimental treatment which they must 
take daily as instructed and must come back to the clinic for regularly scheduled visits.  
 
The patient, or caregiver of each patient will sign the Study Compliance Agreement 
(Appendix D) in which they agree to administer the test medication as instructed by their 
attending physician in compliance with this protocol.  Further, this agreement stipulates 
that the caregiver of each patient will complete their obligations under this protocol as 
instructed by the Investigator and his/her staff; including visit attendance, test form 
completion, reporting of adverse events, and so forth.  Additionally, this agreement 
requests, but does not require, that caregivers provide any ad hoc comments regarding the 
behavior of the patient or their responses to treatment be forwarded weekly to the 
Investigator to document changes in the patient’s condition at home and to add any notes 
to the database that are appropriate to understanding the response of the patient to 
treatment. 
 
After satisfying entry criteria and giving signed informed consent and agree to the 
compliance document, subjects will be enrolled in the trial   
5.1.1  ASSIGNMENT OF PATIENTS TO GROUPS 
At each of the two tested dosage levels, the first 5 patients in each group will be assigned 
to receive the specified dose of either 100 mg t.i.d. or 200 mg t.i.d., whereas the 
following 15 patients in that group will be randomized to receive the specified dosage or 
placebo. After being assigned to a treatment arm each patient will be assigned a study 
number comprised of a 2-digit site identifier and a 3-digit patient identifier. 
 
No patient will receive more than 100 mg t.i.d until permission to escalate to 200 mg 
t.i.d. is obtained from the FDA after their review of the first week of safety and PK 
data from the 100 mg group.  This permission will follow if the safety data submitted 
for the first week of dosing in the Assigned Dosage Group is assessed by the FDA to be 
sufficiently safe to allow for a dosage escalation. 
 
Each study site will be identified by a 2-digit number beginning with 01.  Each patient 
screened for admission into the study will be assigned a unique sequential number that 
also identifies their study site.  Thus, the 1st patient enrolled in the first study site will be 
patient 01-001 and the 2nd patient enrolled at the 2nd study site will be patient 02-002.

CONFIDENTIAL DOCUMENT 
Study numbers will not be assigned until a patient is qualified and entered into the trial.  
Screening failures will not be assigned numbers.  However, a list of screen failures and 
their demographic data will be maintained by the Investigator. 
 
Patients will be enrolled and receive their first dose within 3 weeks of completing the 
screening procedure. 
 
5.1.2  
ASSIGNED DOSAGE GROUPS 
The first 5 patients in each dosage group will be assigned to receive the active medication 
in an open label fashion.  These groups will be treated identically to the Randomized 
group with 4 exceptions: 
• Patients in this group will have blood samples drawn at baseline before and 1h 
after dosing, and at each active treatment visit 1h after dosing to determine their 
blood levels of L1-79 for pharmacokinetic and pharmacodynamics analysis. 
• Patients in this group will have EKG taken at baseline and within 3 days prior to 
the Week 1, 2, 3, and 4 treatment interval visits as well as at the 1 week and 4 
week post dosing follow-up visits.  Patients in this group will have vital signs, 
physical exam, and ASD assessments will be performed, including: ABC, SRS, 
RBS-R, CGI-S, and CGI-I be assessed at 1-week post-dosing Patients in this 
group will have blood and urine samples drawn at baseline at baseline before 
dosing, at week 1, 2, and 3 active treatment visit 1h after dosing, and at the 1 
week post dosing follow up for safety analysis. 
 
Following the Week 1 visit for these patients and the completion of all assays for samples 
taken at the Week 1 visit, a report will be submitted to the FDA on the results from these 
patients.  A second report on the results of these patients will be sent to the FDA 
following the final 1-week post-dosing visit for this group of patients. 
 
5.1.3 RANDOMIZED GROUP 
Following the enrollment of 5 open label patients as described in the Assigned Dosage 
Groups, an additional 15 patients at each dose level will be randomized 2:1 to receive 
either active drug or placebo (2 active to each placebo patient.  These patients will be 
treated identically to those in the Assigned Dosage Groups with 3 exceptions: 
1. No pharmacokinetic samples will be drawn, 
2. No EKG will be performed 
3. They will not have the 1 week follow-up, just the 1 month follow up. 
 
After being randomized to a treatment arm each patient will be assigned a study number 
comprised of a 2-digit site identifier and a 3-digit patient identifier as described above.

Study numbers will not be assigned until a patient is qualified and entered into the trial.  
Screening failures will not be assigned numbers.  However, a list of screen failures and 
their demographic data will be maintained by the Investigator. 
 
Patients will be enrolled and receive their first dose within 3 weeks of completing the 
screening procedure. 
5.1.4 PLACEBO ROLLOVER TO ACTIVE 
• If the Investigator in collaboration with Yamo Pharmaceuticals (the manufacturer of 
the drug) believes that the L1-79 is sufficiently well tolerated and clinically useful to 
warrant continued treatment, then patients receiving placebo will be eligible for a 4 
week course of treatment with L1-79 as outlined for the other patients treated with 
active drug in this protocol.  At the present time, the permitted course of therapy does 
not extend past 4 weeks. 
• The random code will only be broken after the last patient in a group has completed 
the last scheduled follow-up visit. 
• Placebo treated patients who qualify for active treatment in a rollover fashion, and 
who desire to do so, will be indicated in the eCRF as has having affirmatively 
requested active treatment under the protocol.  They will then qualify for extended 
treatment with active medication under the existing protocol and new, active, 
medication will be assigned to them on an open label basis at the same dose as their 
group had been receiving. 
• Placebo rollover patients will be seen at 3 scheduled visits plus a follow-up visit as 
described in Appendix B.   
o There will be no Screening, as patients have already been screened 
o Rollover patients will not have any PK tests conducted 
o Baseline Visit

5.1.5 EMERGENCY BREAKING OF THE RANDOM CODE 
In the event a patient has an emergency that requires knowing which regimen he was 
receiving in this trial, that information can be obtained by calling (908) 310-7912 or 
(908) 236-9513. This number is for the use of the Investigator or other treating physician 
whose knowledge of the randomization is critical to the treatment of the patient. 
5.2 
Drug Administration 
5.2.1 THE L1-79 REGIMEN 
Subjects will receive either 100 mg or 200 mg or matching placebo t.i.d. for a total of 28 
days of dosing.  The doses of L1-79 were determined based upon preliminary clinical 
research in subjects between 2½ and 24 years of age and doses between 90 and 200 mg 
t.i.d.. 
5.2.2 THE PLACEBO REGIMEN 
The matching placebo regimen consists of inert ingredients matched in taste, weight and 
appearance to the active drug and administered orally t.i.d. for 28 days. 
5.2.3 DOSING INSTRUCTIONS 
The study medication will be dispensed in containers that contain sufficient study drug 
for two weeks of t.i.d. dosing, plus 2 additional doses to be used if needed (44 doses) at 
the Day 0 and Week 2 visits.  In order to maintain the double-blind, each dose will be 

L1-79 for the Treatment of Autism

Protocol No. HT 02-121 
Page - 13 - 
CONFIDENTIAL DOCUMENT 
comprised of 2 capsules as described below.  Thus, each biweekly drug allotment will 
consist of 44 packages of 2 capsules each sufficient for 3 daily doses times 14 days plus 2 
extra doses to be used in the event that a dose or two is lost.  Subjects will be instructed 
to take a dose (2 capsules) in the morning upon arising, afternoon at approximately 4 pm, 
and just prior to bed time.  Capsules can be taken orally, or their contents can be mixed 
with food or drink as deemed necessary by the caregiver to facilitate the administration of 
the medication.  Care will be taken to assure that 8 oz of water are given at the time of 
dosing to maintain hydration.  For subjects unable to swallow capsules the may take the 
drug in food or drink.  Patients should also be cautioned about potential sedative effects 
and instructed not to conduct activities like driving, which require alertness. 
 
5.2.3.1 
First Dose Safety Observation 
The first dose of L1-79 in every patient will be administered at the study site, and each 
patient will be observed for a minimum of 2 hours post-dosing in order to assess adverse 
events.  Special attention should be paid to potential AE known to be associated with 
impaired catecholaminergic function such as dystonias, cardiovascular events, 
extrapyramidal symptoms, and so forth. 
 
5.3 
Potential Side Effects and Treatment 
The levo form of L1-79 (L-AMPT) is marketed under the name of Demser for the 
presurgical treatment of pheochromocytoma.  Demser is prescribed for adults and 
children over 12 at doses between 1-4 g/d, with the lowest label dose of Demser being 
250 mg qid.  This is higher than the highest dosage used in this study.  L1-79 is a 
racemate it contains the dextro form of the amino acid isomer and only 50% of the active 
Demser ingredient as determined by measuring the optical rotation.  L1-79 has been 
tested in rodents and dogs and found to be well tolerated at multiples of the dose to be 
used in this trial.  Based upon 4 week toxicological reports in rats and dogs a sufficient 
toxicology profile has been elaborated to support the use of L1-79 in a 4-week study in 
humans. 
 
At the approved doses of ≥2g/d Demser may be associated with crystalluria, sedation, 
and other effects reported to have been mild.  Mild depression and difficulties in sleeping 
have also been reported at these higher doses.  These effects were observed to be 
transient.  Investigators should instruct subjects and caregivers to maintain patient 
hydration, and to be aware of potential sedative effects that would limit the use of the 
drug when using power equipment or driving.  It should be noted that the highest dose in 
this trial is equivalent to 300 mg of Demser daily, or 15% of the 2 g/d dose. 
 
5.4 
Concomitant Medication 
Patients are permitted only 1 concomitant medication in this trial.  Patients should be 
assessed for concomitant medications during the screening process and weaned down to 
the lowest possible effective level for the duration of this trial, including all follow-up 
visits.

5.5     Clinical and Laboratory Procedures 
Prior to starting any procedure associated with this study, the patient or caregiver must 
give written informed consent (Appendix C) to participate and agree to abide by the 
requirements of this study.  Study personnel experienced with ASD patients and their 
families will take great care to explain in detail and in easy to understand terms the 
purpose, objectives, methods, tests, study schedule, and any other pertinent information 
that might influence the granting of consent to participate.  Similarly, study staff will take 
great care to elicit and answer all questions that arise in the course of describing this trial 
and will answer all questions fully.  A copy of the consent form will be maintained with 
the patient’s records. 
 
This study will use the local certified clinical laboratory associated with the Investigators 
practice.  CLIA certification and normal values will be obtained by the Investigator and 
provided to the Sponsor for each clinical lab used, and normal values will be updated 
after each calibration cycle. 
 
A schedule of events can be found in Appendix A. 
5.5.1 SCREENING EVALUATION FOR INCLUSION/EXCLUSION CRITERIA 
Criteria for inclusion and exclusion of potential study subjects are outlined in Sections 
4.1 and 4.2.  All potential study subjects must be evaluated for the presence of all 
inclusion criteria and the absence of all exclusion criteria before enrollment in this study. 
5.5.1.1 
 
Medical History  
Background information will be recorded once for each patient during screening for this 
study.  This information includes age, gender, race and medical history including 
concomitant diseases and conditions associated with organ systems and chronic 
infectious diseases, as well as a detailed family history to ascertain any heritability of 
autism, cognitive dysfunction, epileptic or other diseases associated with autism. 
 
Caregivers will be questioned about the patient’s prenatal history, possible exposure to 
pesticides or other toxins, pre-natal maternal inflammation, fetal alcohol syndrome, and 
drugs taken by the mother during prior to, during, and after pregnancy. 
 
In addition to the usual medical history questions asked of patients with ASD, patients 
and caregivers will be queried about their use of alcohol sugars such as xylitol, mannitol, 
and the dental health of the study subjects. 
5.5.1.2 
 
Physical Examination 
All subjects will have a complete physical examination including vital signs at screening 
and again at the 4-week post-dosing follow up visit.  Height will be recorded once at 
screening.  Weight will be recorded at each physical exam.   Any change from screening 
physical examination that is clinically significant and noted during follow-up will be 
recorded in the patient’s medical record and on the CRF.  Additionally, a physical exam 
will be conducted on the Assigned Dosage Patients at their 1 Week Follow Up visit.

CONFIDENTIAL DOCUMENT 
5.5.1.3 
 
Vital Signs  
Vital signs obtained for each patient include orthostatic blood pressure 
(systolic/diastolic), heart rate (radial pulse) and respiratory rate at screening and all 
scheduled clinic visits.   
5.5.1.4 
 
Blood Pressure 
Blood pressure (bp) will be taken at every visit. Orthostatic blood pressure will be 
assessed by recording blood pressure while sitting and then while standing in the 
following manner:  
• Patient will sit down for 5 minutes 
• Measure blood pressure and pulse rate 
• Have the patient stand 
• Repeat blood pressure and pulse rate measurements after standing 1 and 3 minutes 
A drop in bp of ≥20 mm Hg, or in diastolic bp of ≥10 mm Hg, or experiencing 
lightheadedness or dizziness is considered abnormal.  
5.5.1.5 
 
Electrocardiograms 
• In order to assess any possible changes in electrocardiographic variables, an EKG 
will be taken and read as specified in section 5.5.2.  A pediatric cardiologist will read 
all EKGs. 
5.5.1.6 
PK Assessment 
• Blood samples will be taken at baseline both before and 1h after dosing, and at each 
of the 4 weekly active treatment visits 1h after dosing in the Assigned Dosage Group 
for the purpose of measuring serum levels of L1-79.  
5.5.1.7 
 
Concomitant Medications 
As documented in the history and at the screening visit, no patient currently receiving 
polytherapy for autism will be enrolled in this trial.  Any agent which is being prescribed 
for the treatment of ASD will be noted as such in the eCRF.  Subjects identified for 
accrual into this trial will be weaned to the lowest dose of any prescribed psychotropic 
medication over the two to four weeks preceding their screening visit deemed effective 
by the Investigator. 
 
All prescription and nonprescription medication taken by the patient from 14 days prior 
to screening and up to and including the final visit will be recorded in the medical record 
and on the eCRF.  Any addition, deletion, or change in the dose of these medications 
must be recorded.  
 
Because the mechanism of L1-79 is the inhibition of catecholamine synthesis, the 
potential exists for interactions with neurologically active, and other, drugs.  Investigators 
will be diligent in observing potential drug interactions and should appropriately reduce 
the dose of any concomitant medication that is observed to be potentiated in the presence 
of L1-79.

Blood Draws for Subsequent Testing 
• At the time of the sample collection for the analysis of serum chemistry 2 additional 
red top tubes of blood will be drawn, spun down to separate the cells, and the serum 
will be frozen and stored for subsequent analysis.  Samples will be labeled with the 
subjects’ initials, study number, date of visit, and identified as a pre- or post-treatment 
sample.    
• Frozen serum samples will be stored at the site for up to 7 years and saved for 
analysis after which they will be destroyed.  It is likely that these samples will be 
analyzed for catecholamine and lipid fractions in the future.  However, the precise 
analysis has yet to be determined, and will be based upon future research results. 
Separate informed consent will be obtained prior to any future analysis of these 
specimens, however, all samples will be identified only by protocol and patient 
numbers.  No other patient identifiers will be used.

• The Spense Anxiety Scale (SAS) will be administered at baseline and at the 4 week 
follow-up visit, and also at the 1 wk follow up visit for the assigned dosage groups. 
5.5.2 EKG 
EKG will be taken by an outside pediatric cardiologist.   
• Patients who are screened and those who participate in this study will have 
appointments made for them by the Investigator or his study staff with the 
cardiologist associated with the study site.   
• All required EKG appointments will be made upon the accrual of a patient into 
this trial and that information will be provided to the caregiver in writing. 
• Detailed instructions will be provided to the caregiver regarding the directions to 
the cardiologist’s office, contact information, times of the appointments, and it 
will be confirmed that these EKG appointments are an essential part of the study 
and all visits must be made at the scheduled times. 
• The Investigator and/or the study staff will be responsible for obtaining the results 
of these EKG and entering them into the database prior to the next scheduled 
study visit. 
• EKG will be taken as part of the baseline screening procedure for the Assigned 
Dosage Group patients (Groups 1 & 3).

days prior to the Week 1, 2, 3, and 4 treatment interval visits as well as at the 1 
week 4 week post dosing follow-up visits.   
• EKG will be taken as necessary in any patient who manifests a potential 
cardiovascular AE in response to L1-79 such as tachycardia or bradycardia. 
• In the event that 2 or more cardiovascular AE are reported in a group additional 
EKG may be warranted and a determination will be made as to the proper course 
of action at that time. 
5.6

CONFIDENTIAL DOCUMENT 
Sample collection methods are presented in Appendix D. 
 
5.9.3.2 
Electrocardiograms 
Patients in the assigned group will receive EKG as specified in section 5.5.2.  In the event 
any EKG abnormalities are noted, additional EKG may be required as described in 
section 5.5.2. 
 
5.9.3.3 
1-week Follow-up visit 
• At the request of the FDA, patients in the assigned dosage groups will be followed for 
at one week while continuing to receive their assigned dose of L1-79 t.i.d. in order to 
assess the safety parameters described herein before submitting a report describing 
the results of the safety testing, PK/PD results, and EKG to the FDA for their 
assessment.  For the 100 mg t.i.d. group a favorable review of this report is required 
to enroll the 200 mg t.i.d. dosage group. 
5.9.4 PROVIDING L1-79 SUBSEQUENT TO THIS STUDY 
If, in the opinion of the sponsor and the Investigator that L1-79 therapy is well tolerated 
and provides a beneficial therapeutic effect, an amendment to this study will be 
considered to provide L1-79 in an open label manner for subjects in this study who have 
either received placebo or who would likely benefit by receiving additional treatment at 
the end of the study.   
 
Depending upon the results obtained during this investigation, if warranted, the sponsor 
may extend this study if the FDA permits.  In the event that L1-79 therapy is found 
appropriate, the sponsor may adjust the dosing consistent with the findings of this trial 
and continue treating subjects beyond the specified treatment duration herein in a manner 
compliant with the FDA guidelines. 
5.10 
Discontinuation of Study Subjects 
A patient may be discontinued for the following reasons: 
• Non-compliance with treatment regimen or follow up requirements 
• Lost to follow-up 
• Patient and/or care giver requests voluntary withdrawal 
• Adverse event sufficient in the opinion of the Investigator to warrant cessation of 
treatment 
• Adverse event requiring unblinding of the patient’s assigned treatment 
• Investigator decision 
Discontinuation for any reason will be documented in the eCRF and supporting 
documentation will be added to the patient file.  Appropriate treatment will be provided 
for any disease or syndrome.

CONFIDENTIAL DOCUMENT 
All subjects who receive a single dose, irrespective of discontinuation, will be followed 
for a period of 4 weeks subsequent to the first dose in order to determine whether the 
treatment was safe. 
5.11 
Recording of Adverse Events 
Each patient will be observed and queried in a nonspecific fashion by the Investigator or 
designee at each visit during the study for any new or continuing AE that occurs since the 
previous visit.  Any AE reported by the patient or noted by the Investigator or designee 
will be recorded in the Adverse Event section of the database.  The following information 
will be recorded for each reported AE: description of the event, time of onset, time of 
resolution, severity, relationship to the study drug determined (as opposed to NSAID or 
antibiotic related toxicity), outcome, management of the AE, and outcome.  Each AE will 
be classified as serious or not.  Serious AE will be handled according to section 5.11.6. 
 
Adverse events will be treated as deemed appropriate by the Investigator and the results 
will be recorded in the case report form, including any therapeutic regimens prescribed, 
hospitalization, surgery, discontinuation from the study or any other action related to the 
adverse event.  
 
The Investigator should use the following definitions to classify the relationship of each 
adverse experience to the test treatment. 
 
5.11.1 NOT RELATED  
This category applies to those adverse experiences that, after careful consideration, the 
Investigators determines are clearly and incontrovertibly due to extraneous causes 
(disease, environment, etc.). 
5.11.2 UNLIKELY: (MUST HAVE AT LEAST TWO OUT OF FOUR CRITERIA)   
In general, this category can be considered applicable to those adverse experiences that, 
after careful medical consideration at the time they are evaluated, are judged to be 
unrelated to the study drug.  An adverse experience may be considered unlikely to be 
related if or when: 
• The adverse experience does not follow a reasonable temporal sequence* from 
administration of L1-79 or placebo. 
• The adverse experience could readily have been produced by the patient’s clinical 
state, environmental or toxic factors, or other modes of therapy administered to 
the patient. 
• The adverse experience does not follow a known response pattern to the suspected 
drug. 
• The adverse experience does not reappear or worsen when the drug is re-
administered. 
                                                 
*Temporal sequence is defined as an association between the suspect drug and the observed reaction or event in which 
the suspect drug was present prior to the reaction or event as defined by history or drug blood level.

Investigational New Drug Protocol 
 
 
 
 
 
Protocol No. HT 02-121 
Page - 26 - 
CONFIDENTIAL DOCUMENT 
5.11.3 POSSIBLE: (MUST HAVE AT LEAST TWO OUT OF THREE CRITERIA)  
This category applies to those adverse experiences for which, after careful medical 
consideration at the time they are evaluated, a connection with the study drug 
administration appears unlikely but cannot be ruled out with certainty.  An adverse 
experience may be considered possibly related if or when: 
• The adverse experience follows a reasonable temporal sequence from the time of 
immunization. 
• The adverse experience follows a known response pattern to the study drug. 
• The adverse experience could have been produced by other factors such as the 
patient’s clinical state, therapeutic interventions, or concomitant drugs 
administered to the patient. 
 
5.11.4 PROBABLE: (MUST HAVE THREE OUT OF FOUR CRITERIA)  
This category applies to those adverse experiences which, after careful medical 
consideration at the time they are evaluated, are felt with a high degree of certainty to 
be related to the study drug.  An adverse experience may be considered likely related 
if or when: 
• The adverse experience follows a reasonable temporal sequence from the time of 
drug administration. 
• The adverse experience follows a known response pattern to the study drug. 
• The adverse experience cannot be reasonably explained by other factors such as 
the patient’s clinical state, therapeutic interventions, or concomitant drugs 
administered to the patient. 
• The adverse experience is confirmed by improvement of the symptoms on de-
challenge (e.g., the removal withdrawal, or discontinuation of the suspected drug 
from the patient’s therapeutic regimen). 
5.11.5 DEFINITE: (MUST HAVE ALL FOUR CRITERIA)  
This category applies to those adverse experiences that the Investigator feels are 
incontrovertibly related to the study drug.  An adverse experience may be assigned an 
attribution of definitely related if or when: 
• The adverse experience follows a reasonable temporal sequence from the time of 
drug administration. 
• The adverse experience cannot be reasonably explained by the known 
characteristics of the patient’s state, environmental or toxic factors, or other 
modes of therapy administered to the patient. 
• The adverse experience occurs immediately following study drug administration, 
or improves on stopping the drug (de-challenge), or reappears on repeat exposure 
(re-challenge) (Note: this is not to be construed as requiring re-exposure of the 
patient, however, a category of definitely related can only be used when 
recurrence is observed). 
• The adverse experience follows a known response pattern to the study drug.

CONFIDENTIAL DOCUMENT 
5.11.6 ASSESSMENT OF THE SEVERITY OF ADVERSE EVENTS  
Severity of an adverse experience is defined as a qualitative assessment of the degree of 
intensity of an adverse experience as determined by the Investigator or reported to 
him/her by the patient.  The assessment of severity is made irrespective of drug 
relationship or seriousness of the event using MEDRA criteria. 
 
All serious and life threatening adverse experiences must be reported by entering them 
into the database and no later than 24 hours after the Investigator has become aware of 
them.  This will generate automatic emails to the study Sponsor and the study monitors.  
The patient must be monitored carefully until the condition disappears and/or the etiology 
is defined. 
 
All serious and life threatening adverse experiences must be reported by the Investigator 
to the appropriate IRB/EC in writing, as well as the study sponsor. 
5.12 
Recording of Concomitant Therapy 
All prescription and nonprescription medication (including vitamins and herbal 
supplements) taken by the patient from screening to the end of the study will be recorded 
in the patient’s medical record and the eCRF.  Any additions, deletions or changes in the 
dose of these medications should be entered on this form.  Generic names should be used 
to eliminate confusion that may result from trade names.  The list of all concomitant 
medications will be reviewed at each visit, and adjusted as appropriate. 
5.13 
Study Discontinuation Criteria 
The occurrence of a grade 3 or 4 AE in any patient will result in the immediate 
discontinuation from this study. In the event of a grade 2 AE, the Investigator, at their 
discretion, may withhold treatment until the event resolves to grade 1 or less. 
 
The Sponsor may at its discretion terminate the study as a whole if conditions warrant 
this action.  The study site Investigator bears responsibility for orderly discontinuation of 
the study subjects enrolled at his/her study site. 
5.14 
Dose Adjustment and Stopping Rules 
As this is a double-blind trial and the doses administered to a given patient are not known 
to the Investigator or the sponsor.   In the event a grade 1 or 2 adverse event occurs, the 
regimen will be paused until a resolution of the event occurs and the Investigator feels it 
is safe to continue.  Should the Investigator feel it is not safe to continue, or should the 
event reoccur that patient will be terminated from this trial and appropriate therapeutic 
measures taken.  Any dosing hiatus or discontinuation will be noted in the case report 
form. 
 
In the event a patient experiences a grade 3 (Severe) or 4 (Life Threatening) adverse 
event medication will be discontinued immediately and will not resume until the 
Investigator and the DMC have agreed that it is safe to do so.

CLINICAL TRIAL SUPPLIES 
7.1 
Test and Non-Test Articles 
The active test article, L1-79 and matching placebo will be supplied to the Investigator as 
capsules in sealed bottles of 100 capsules of L1-79 or matching placebo.  The study 
pharmacist will allocate the appropriate number of active or placebo into secondary 
packaging for distribution to subjects. 
 
Each dose will consist of 2 capsules.  Doses for subjects in the 100 mg group will be 
comprised of one 100 mg capsule and 1 placebo capsules while those in the 200 mg 
group will consist of two 100 mg capsules for each dose.  
 
A drug log will be maintained by the Investigator and all dispensed medications as well 
as unused medications and those returned by subjects or their caregivers will be logged 
out and logged in.  Empty drug containers will not be returned, but those containing 
medication will be returned at visits for study weeks 2 and 4 and will be counted, logged 
in, and stored by the Investigator until the end of the study. 
7.2 
Preparation of the Study Drugs 
The study pharmacist will prepare drugs for dispensing to the subjects to take home.  
Bottles of 100 capsules will be provided for placebo and 100 mg of L1-79.  The 
pharmacist will package the study medications as individual doses at the study site in the 
following manner: 
 
7.2.1 ASSIGNED DOSAGE PATIENTS 
• At each site, the pharmacist will prepare 44 individual doses (3 doses/d x 14 days 
+ 2 extra doses) with each dose in an individually labeled envelope for six 
patients (to allow for 1 drop out) in each dosage group.  Although not all 
5Assigned Dosage Patients in a dosage group will be treated at each site there will 
be sufficient drug to accommodate all of these patients if one site can enroll faster 
than another. 
• For 2 weeks of daily dosing, each patient would receive 3 x 14 = 42 + 2 extra 
doses for a total of 44 doses, each dose will be individually packaged in 
envelopes.  The envelopes will be placed in a cardboard box 
• Since 2 weeks is the limit for how much drug the FDA guidelines will allow study 
materials to be packaged in this manner, this process would have to be repeated 
twice at each study site 
7.2.2 RANDOMIZED PATIENTS 
• The pharmacist will place individual doses comprised of 2 capsules each in 
individual envelopes for 12 subjects (to allow for 2 dropouts) in 3 different 
treatment groups in the following manner: 

L1-79 for the Treatment of Autism 
Investigational New Drug Protocol 
 
 
 
 
 
Protocol No. HT 02-121 
Page - 32 - 
CONFIDENTIAL DOCUMENT 
o Each dose is comprised of 2 capsules to maintain a double-blind.  They are 
distributed as: 
 Placebo group: 2 placebo capsules 
 100 mg group: 1 x 100 mg capsule and 1 x placebo 
 200 mg group: 2 x 100 mg capsule  
• For 2 weeks of daily dosing, each patient would receive 3 x 14 = 42 + 2 extra 
doses for a total of 44 doses, each dose will be individually packaged in 
envelopes.  The envelopes will be placed in a cardboard box 
• Since 2 weeks is the limit for how much drug the FDA guidelines will allow study 
materials to be packaged in this manner, this process would have to be repeated 
twice at each study site. 
• Because of the double-blind nature of the trial, each box is labeled with a sticker 
that has the study number and patient study number which derives from a random 
code that links study numbers with dosage groups. 
7.3 
Dispensing the Study Drug 
Study drug will be dispensed as a two week supply during study weeks 0 and 2 visits..  
Drugs will be allocated to subjects on a randomized and double-blinded basis.  Two 
containers of 42 doses will consist of the study drug for each patient.  Each container will 
be labeled with the patient’s study number. 
 
At the accession visit prior to week 1 and at the post week 2 visit each patient will receive 
a container of drug corresponding to their study number.  Neither the Investigator or the 
sponsor will know to which dosage group any patient is assigned. 
 
7.4 
Labeling of Test Articles 
Each drug container will contain 2 weeks of study drug and two extra doses to be used in 
the event a dose or two is lost, and will be labeled as follows,  
• Protocol number 
• Storage requirements 
• Investigational use statement “Experimental Clinical Use Only” 
 
Each dose consisting of 2 capsules will be individually wrapped and provided within the 
larger container will be labeled as follows:

8.1.1 NON-SERIOUS ADVERSE EXPERIENCE REPORTING 
Non-serious adverse experiences will be reported on the appropriate electronic case 
report form (eCRF) as described in Section 5.11.  The Sponsor is responsible for the 
reporting of non-serious adverse experiences to the FDA in the IND annual report. 
8.2 
Electronic Data Collection 
Data will be collected via EDC.  All data is to be entered within 3 days after each patient 
evaluation.  Data that requires transcription will be transcribed within 3 days. 
 
All entries into the database must be supported by original source documentation (e.g., 
laboratory reports) maintained at the investigational site.   
 
Correction(s) of data in the database may only be made in a manner that indicates the 
error and leaves the previous entry identifiable by entering the correct values next to 
those marked as incorrect.  An audit trail will be generated automatically as the data 
capture system will note the person making a change, the date of the change, and the 
original information will be maintained as well as the corrected information. 
 
The Investigator is required to review all entries into the database and electronically sign 
where indicated to attest to the accuracy of the data recorded on the form. 
8.3 
Investigator Requirements 
8.3.1 PRIOR TO STUDY INITIATION 
Prior to study initiation, the Investigator will complete and forward the following 
essential documentation:

should be written to be easily understood by the patient or legal guardian.  All aspects of 
this study including objectives, methods, schedules and so forth should be explained in 
easy to understand terms, and questions should be elicited and answered in full in order to 
enable a truly informed consent.  The patient/legal guardian should be given the time to 
read and understand the statement and be afforded the opportunity to ask questions before 
signing his/her consent and dating the document.  The patient/legal guardian should 
receive a copy of the written statement once she and the Investigator have signed the 
informed consent.  
 
The informed consent form must be considered as a part of the protocol.  It is to be 
submitted by the Investigator along with the protocol for approval to the IRB. 
 
No study procedures will be initiated prior to obtaining a valid, signed, informed consent. 
 
The informed consent form is presented in Appendix C. 
8.3.3 INSTITUTIONAL REVIEW BOARDS (IRB) 
The Investigator assures that the Institutional Review Board (IRB) for the initial and 
continuing review and approval of this clinical study complies with the requirements set 
forth in 21 CFR Part 56 and all relevant ICH GCP guidelines. 
 
No one may amend this protocol other than the Sponsor.  The Investigator also assures 
that he/she will promptly report to the IRB all changes in research activity and all 
unanticipated problems involving risks to human subjects or others, and that he/she will 
not make any changes in the research until the IRB has approved the changes, except 
where necessary to eliminate immediate hazards to human subjects.  Documentation of 
approval or notification must be forwarded to Hoffman Technologies Inc. for any 
amendment.  
 
The Investigator must also report to his/her IRB at least yearly on the progress of the 
investigation and obtain written approval to continue the study beyond the time stated in 
the original approval.  The Investigator must notify the IRB of the conclusion of the study 
within three months after completion, termination or discontinuation of the study.

8.3.4 RECORDS RETENTION 
The sponsor and US Federal law requires that a copy of all records (e.g., informed 
consent documents, laboratory data slips, source documents, IND safety reports, test 
article dispensing records, etc.) that support case report forms of this study be retained in 
the files of the responsible Investigator for a minimum of two years following 
notification by the sponsor that: 
• all investigations at all sites are completed, terminated, or discontinued; or  
• the last marketing application in an ICH region (including US Food and Drug 
Administration) has been approved; and 
• There are no pending or contemplated marketing applications in an ICH region. 
 
Study-related records identifying the subject will be kept confidential and, to the extent 
permitted by applicable law, will not be made public.  In the event the results of this 
study are published all subjects’ identity will remain confidential.  However, 
representatives of the U.S. Food and Drug Administration (FDA) will be allowed to 
examine all patient records under strict confidentiality measures.  In addition, 
representatives of the Sponsor, such as the study monitor, the IRB and possibly 
representatives of foreign regulatory authorities (should approval of L1-79 be sought in 
other countries) may also have access to patient records that have been redacted to omit 
patient identifiers other than the study number and patient initials. 
 
The sponsor may use data generated by this protocol to support regulatory filings in other 
countries.  In order to be in compliance with foreign regulatory agencies, the Investigator 
is required to maintain all study records for a period of 10 years following the conclusion 
of this study. 
 
If the Investigator retires, relocates, or for other reasons withdraws from the 
responsibility of keeping the study records, custody must be transferred to a person who 
will accept the responsibility.  Hoffman Technologies must be notified in writing of the 
name and address of the new custodian. 
8.3.5 ACCOUNTABILITY AND STORAGE OF TEST ARTICLES 
The Investigator is responsible for maintaining an accurate, up-to-date dispensing log for 
all study drugs supplied by Hoffman Technologies Inc. that includes all of the 
information presented in section 7.4.  All study medication received and dispensed by the 
Investigator will be inventoried and accounted for throughout the study.  The study 
medication must be stored in a restricted area with limited access.  Contents of the study 
medications of different identities or concentrations must not be combined. 
8.4 
On-site Monitoring and Audits 
The study will be periodically monitored by a representative of the study Sponsor.  It is 
the responsibility of the Principal Investigator to provide all study records, including case 
report forms, source documents, etc., for review and inspection by the monitor at their 

L1-79 for the Treatment of Autism 
Investigational New Drug Protocol 
 
 
 
 
 
Protocol No. HT 02-121 
Page - 39 - 
CONFIDENTIAL DOCUMENT 
visit.  The IRB may also ask to review certain case report forms.  Likewise, 
representatives of FDA may audit the study records including patient records. 
 
The US Food and Drug Administration, in the person of a scientifically trained and 
properly authorized employee of the agency, may request access to all study records, 
including source documents, for inspection and copying. 
8.5 
Amendments to the Protocol 
The Sponsor reserves sole authority to amend this protocol, and will not amend or modify 
the protocol without notifying the Investigator.  All amendments must be approved by the 
study sponsor prior to implementation.  The Investigator must attempt to notify the 
sponsor before submitting all amendments to the IRB for notification and approval.  
Deviations from the protocol that are required to address immediate patient safety 
concerns are permitted providing sponsor is notified of such changes prior to their 
execution. 
8.6 
Departure from Protocol 
Departure from study protocol is not permitted.  Should an occasion occur in which the 
protocol has not been followed, the Investigator is required to provide a written 
description of the reason(s) that the protocol was not followed and what remedial action 
will be taken to prevent future occurrences.  A note to file should be included in the 
subject record to provide information about what exactly happened and whether this 
deviation affected the safety of the patient.  In the event an Investigator feels an 
exemption from this protocol is appropriate the Investigator should discuss a possible 
waiver with the sponsor. 
 
Repeated departures from the protocol will result in the immediate removal of the 
Investigator and/or termination of the investigational site.  All data collected from such a 
site will be used to the extent possible, and subjects will be followed for safety as 
described within this protocol. 
8.7 
Duration of Trial and Circumstances for Termination 
The Investigator agrees to complete their portion of the data entry for this study within 14 
days following the final patient’s study completion visit.  
 
Extension beyond this timeframe is at the discretion of the study sponsor with consent 
and approval of FDA and the governing IRB.  It is agreed that, for reasonable cause, the 
Investigator or the sponsor may terminate this study, provided written notice is submitted 
at a reasonable time in advance of intended termination. The Sponsor reserves the right to 
terminate the study without advance notice under the following circumstances: 
• noncompliance with the protocol; 
• slow enrollment (i.e., insufficient to reasonably complete the study within the 
prescribed timeframe); 
• safety concerns, 
• manufacturing issues, 
• discontinuation of the study protocol,

your child may take part, it is important for you to understand why the research study is being 
done and to understand its possible risks and benefits in order to make an informed decision.  
This process is known as informed consent. 
 
 
As the parent or legal guardian of a study participant that is not legally permitted to consent to 
be in a research study on his/her own behalf, it is necessary that you sign this Informed 
Consent Form.. If there will be a caregiver assisting the child, then the caregiver must sign the 
Study Compliance Agreement provided separately. 
 
This form gives detailed information about the research study that your study doctor will 
discuss with you.  Once you understand this study, you will be asked to sign this form if you 
wish your child to participate. 
 
There will be no costs to you for your child’s participation in the research study.  The Sponsor 
will cover the costs of the study medication and all study related procedures. If your child’s 
caused injury that is confirmed to be due to his/her participation in the study, the Sponsor will 
cover all the procedures and/or medications in accordance with the Law.  
 
This study is conducted under an approved FDA Investigation New Drug application.   Please 
read the following information carefully and ask the study doctor listed above for more 
information if anything is not clear.  
 
Introduction 
 
Dr. Peter Halas is studying a possible treatment for autism.  It is an investigational drug named 
L1-79.  An investigational drug is one that is not currently approved by the United States Food 
and Drug Administration (FDA). L1-79 is very similar to a marketed drug called Demser that 
was approved by the FDA in 1979. L1-79 has been tested in animals and found to be safe at 
doses higher than those used in this trial.  It has been used experimentally to treat cancer 

L1-79 for the Treatment of Autism 
Investigational New Drug Protocol

CONFIDENTIAL DOCUMENT 
subjects in combination with other agents and has been well tolerated. L1-79 has also been 
given to a small number of subjects with autism and has also been safe and well-tolerated in 
these subjects. 
 
Historically Demser has been shown to be safe in higher amounts when taken for the duration 
of time you will be taking L1-79.  Although the L1-79 has been used in people before on a 
very limited basis, it has been tested in a number of animal species, including dogs, and shown 
to be safe at doses much higher than those your child will be exposed to. 
 
L1-79 has already been given to a small number of children with autism and without adverse 
events.  It is not known if this treatment will benefit everyone, which is why we are testing it 
with your child.  Your child’s doctor believes that this medication may help your child, and 
that is why he/she has been selected to participate in this study if you agree to your child’s 
participation.   
 
The study you are considering for your child is the first time L1-79 has been administered to 
people with autism under strict clinical trial guidelines.  A total of 40 people with autism will 
participate in this study.  Participants will receive either 200 or 100 mg of L1-79 three times a 
day or a sugar pill three times daily for 28 days (4 weeks).  Your child will be randomly 
assigned by chance (like the flip of a coin) to receive either the study medication or sugar pill.  
For each patient randomly assigned to receive placebo, 2 patients will be randomly assigned to 
receive L1-79.  Neither you or your child, nor the study doctor will  know which of these 
treatments your child receives.  In case of an emergency, however, the study doctor can get 
this information. During the study your child will receive one of the two amounts of L1-79 or 
sugar pill for 4 weeks during which your child will return to the clinic 4 times followed by 4 
more weeks of observation without L1-79 during which your child will return twice to the 
doctor.  Some patients may also have an additional visit to be evaluated at 1 week after dosing. 
 
The risks and benefits of this study are explained below. 
 
Purpose 
 
The purpose of this study is to determine if the drug called L1-79 is safe in the manner that it 
is given in this study, and to see if it has a beneficial effect on the symptoms of autism.  
 
Procedures 
 
Before any study-related tests and procedures are performed, you will be asked to read and 
sign this consent document.  Over the course of the study staff will measure and record blood 
pressure, heart rate, breathing rate, body temperature, height and weight, and blood and urine 
samples will be taken.  Blood samples for determining drug levels in the blood will be taken at 
each study visit for some patients depending on their group assignment.  You will be informed 
if your child is one of those patients.  Electrocardiograms will be taken weekly for some 
patients.  You will be informed if your child will be one of those patients.  The doctor will ask 
you questions about your child’s medical history and any medications that your child is 

L1-79 for the Treatment of Autism 
Investigational New Drug Protocol 
 
 
Protocol No. HT 02-121

CONFIDENTIAL DOCUMENT 
currently taking to make sure that he/she meets the requirements of this research study.  In 
addition, different question and answer tests will be taken during this study.   
 
You will be given capsules of L1-79 to take home.  The study doctor or the doctor’s staff will 
follow your child for any adverse effects that he/she may experience after he/she receives the 
study medication.  You agree that your child will take the study medication as directed, 3 
times per day for 28 days.  One dose will be taken upon arising, one at approximately 4 pm, 
and one dose will be taken at bedtime. 
 
It is important that you keep unused study medication out of the reach of children and 
those of limited ability to understand and that the study medication is only taken by the 
research participant. 
 
If your child takes part in this research study they will have the following tests and procedures: 
• Blood tests to follow blood counts (red cells, white cells and platelets) and to monitor 
his/her body function such as liver function and kidney function. Approximately three 
(3) tablespoons of blood will be drawn at the beginning to see if your child qualifies for 
the study and at week 4 after starting the study so that the doctor can perform 
laboratory studies to check the blood levels of certain chemicals in your child’s body.   
• Some patients will have blood taken to analyze the amount of the study drug that is in 
the blood. 
• Also, at the same time, another 3 tablespoons of blood will be taken and stored frozen 
for use in future analysis in order to determine if changes seen in blood chemicals 
correspond to changes in your child’s disease.  Samples will be stored frozen labelled 
with only the protocol and patient numbers, for up to 7 years after which time they will 
be destroyed.  However, once the samples have been analyzed, the data will be stored 
in a confidential manner and consent may no longer be withdrawn.  It is not known 
when these samples will be used nor what analyses will be performed.  However, you 
may refuse to allow these blood samples to be used in this procedure and your child’s 
blood will not be stored.  Furthermore, you may withdraw consent for use of your 
child’s blood samples at any time (even after the blood samples have been stored) by 
speaking with the study doctor listed on page one of this informed consent or a member 
of his staff  and your child’s participation in the study will not be jeopardized in any 
way. If requested, the samples will be destroyed and any data removed from the 
database. 
• Urine analysis to determine if any abnormalities occur in the urine 
• Physical examinations

• Standard tests used to measure the symptoms of autism will be completed that assess 
the state of your child’s disease in order that changes in his/her performance can be 
determined. 
Your will be required to provide your child’s current address and telephone number to the 
study doctor and to update this information throughout the research study so that the doctor or 
the doctor’s staff will be able to contact you  with any new information.  It will be very 
important that you keep all follow up visits to the study doctor.   
 
Risks 
 
L1-79 has not yet been approved for human use, although it has been tested in various animals 
including dogs and found to be safe at doses considerably higher than those used in this study. 
 
L1-79 has the same chemical structure as Demser, which has been on the market and shown to 
be well tolerated at doses that correspond to the dose your child will receive.  Demser® is used 
in the treatment of patients with a cancer called pheochromocytoma (a tumor or tumors found 
in the adrenal glands which sit atop the kidneys).  Demser uses a formulation of this chemical 
that has greater biological activity and a shorter time in the body than L1-79, and has not been 
found to be effective in treating autism. 
 
The doses of Demser used to treat cancer are higher than those used in this study.  Historically, 
some persons with pheochromocytoma who have taken Demser have reported various side 
effects.  The doses administered to these patients however is greater than the dose 
administered in this study and Demser has a greater biologic effect than L1-79.  The toxicity 
reported for Demser includes:  
 
 
Possible 
• Moderate and severe sedation is reported most commonly but seems to wear off after a 
few days 
• Kidney stones been found in dogs treated with Demser at doses similar to those used in 
humans, and have also been observed in a few patients at the higher doses of Demser.  
• Drooling, speech difficulty, and tremor have been reported in approximately 10 percent 
of patients at the higher dosages.  
• Anxiety and psychic disturbances such as depression, hallucinations, disorientation, 
and confusion may occur which increases with the dose given.  
• Dose related diarrhea occurs in about 10 percent of patients and may be severe.  
• Other dose related adverse events include: 
o Fatigue 
o Increase energy 
o Back pain 
o Breast pain 
o Itching 
o Excessive sweating 
o Tremor 
o Anxiety 

L1-79 for the Treatment of Autism 
Investigational New Drug Protocol 
 
 
Protocol No. HT 02-121 
Page - 48 - 
CONFIDENTIAL DOCUMENT 
o Crystalluria (tiny crystals in urine) 
 
 
 
Rare 
• Slight swelling of the breast, nasal stuffiness, decreased salivation, dry mouth, 
headache, nausea, vomiting, abdominal pain, and impotence or failure of ejaculation 
may occur. Transient episodes of inability to urinate or blood in the urine have been 
observed in a few patients.  
• Hematologic disorders (including changes in blood counts, changes in liver enzymes 
and swelling and redness in the throat have been reported rarely.  
 
It should be noted that none of these events have been seen in any of the patients treated with 
L1-79 at the doses used in this study.  L1-79 has been tested in a small number of subjects 
with cancer and it was well tolerated.  
 
Two of the subjects went to bed early on the 1st day of treatment, which is considered to be 
mild sedation which may have been caused by L1-79, but this only occurred on day 1 of 
treatment.  If your child experiences any pain, discomfort, or unusual health related condition 
you should discuss these with the study doctor or your child’s primary doctor.  It will be 
important to maintain hydration of the patient during the treatment period.  There may also be 
other side effects that we cannot predict.  Many side effects are short lived and go away within 
hours.  This is a new drug and not many people have received L1-79 and not all possible side 
effects may be known at this time. 
 
Your child should exercise special caution when driving, riding a bike or using machinery 
since the study drug may cause drowsiness, lack of coordination or slowed reaction time. 
 
Rarely, allergic reactions can be life threatening but treatment for this will be available.  If any 
side effects appear in other subjects in this study you will be informed of these as they occur.  
If information becomes available that may affect your willingness to allow your child to 
participate in or continue your child’s participation in this study, you will be informed 
immediately.  
 
If your child receives placebo, your child’s condition will not be treated with active medication 
and may become worse, stay the same or improve. 
 
Risks of Study Procedures 
 
•Blood samples:  possible side effects from blood drawing include faintness, 
inflammation of the vein, pain, bruising, or bleeding at the site of puncture.  There is also 
a slight possibility of infection. 
 
•ECG:   Skin irritation is rare but could occur during an ECG from the electrodes or gel 
that is used.

Unforeseen Risks 
Since the study drug is investigational when taken alone or in combination with other 
medications, there may be other risks that are unknown.  All drugs have a potential risk of an 
allergic reaction, which if not treated promptly, could become life-threatening. 
 
Other treatment 
Your child does not have to be in this study to receive treatment for his/her autism. You may 
continue to see the study doctor and have your child receive treatment and continued 
evaluation without agreeing to participate in this study. The study doctor will discuss with you 
the risks and benefits of the alternative treatments.  
 
New Findings 
Any new important information that is discovered during the study and which may influence 
your  willingness to continue your child’s participation in the study will be made available to 
you. 
 
Costs and financial risks 
There will be no costs to you or your child for participating in this study.  The study 
medication L1-79 and all of the care your child receives during this study will be provided free 
of charge.  
Compensation 
 You will not be paid or compensated for expenses associated with your child’s participation in 
this study, nor will you be reimbursed for any travel costs associated with attending the clinic. 
 
 
Benefits 
If you agree that your child takes part in this study, there may or may not be direct medical 
benefit to your child during the time he/she is receiving treatment.  It is unknown if any benefit 
will last after the four weeks of treatment.  Benefits might include increased ease in social 
situations, reduced irritability and anxiety, better ability to converse, and possibly other 
benefits.  The information learned from this study may benefit other subjects with autism in 
the future. 
 
Confidentiality 
 
Every attempt will be made by the Investigators to maintain all information collected in this 
study strictly confidential, except as may be required by court order or by law.   The study 
doctor, authorized representatives of the Sponsor, Dr. Peter Halas as well as the Food and 
Drug Administration (FDA) and the Institutional Review Board (IRB), will be able to have 
access to, and may copy, confidential study-related records from your child’s participation in 
the study.  This means that absolute confidentiality cannot be guaranteed. Only your child’s 
initials and a unique study specific identification number will link your child to the 
information collected.  Any additional information collected will not be used for any purpose 
except reporting to the regulatory agency.

AUTHORIZATION TO USE AND DISCLOSE 
PROTECTED HEALTH INFORMATION 
 
During your child’s participation in this research study, the study doctor and 
study staff will collect or create personal health information about your child (for 
example, medical histories and results of any tests, examinations or procedures 
your child undergoes while in the study) and record it on study documents.  The 
study doctor will keep this personal health information in your child’s study-
related records (that we will refer to as "your child’s study records").  In addition, 
the study doctor may obtain, and include in your child’s records, information 
regarding your child’s past, present and/or future physical or mental health 
and/or condition.  Your study doctor may ask you to sign a separate authorization 
to obtain some or all of your child’s medical records from your child’s doctor.   
Your child’s study records may include other personal information (such as 
social security number, medical record numbers, date of birth, etc.), which could 
be used to identify your child.  Health information that could identify your child 
is called "Protected Health Information" (or "PHI").   
 
Under federal law (the "Privacy Rule"), your child’s PHI that is created or 
obtained during this research study cannot be "used" to conduct the research or 
"disclosed" (given to anyone) for research purposes without your permission.  
This permission is called an "Authorization".  Therefore, your child may not 
participate in this study unless you give your permission to use and disclose their 
PHI by signing this Authorization.  By signing, you are agreeing to allow the 
study doctor and staff to use your child’s PHI to conduct this study.   
 

L1-79 for the Treatment of Autism 
Investigational New Drug Protocol 
 
 
Protocol No. HT 02-121 
Page - 54 - 
CONFIDENTIAL DOCUMENT 
By signing this Authorization, you also are agreeing to allow the study doctor to 
disclose PHI as described below: 
 
• The sponsor of this study and anyone working on behalf of the sponsor to 
conduct this study (referred to as "the sponsor").  The sponsor will analyze 
and evaluate the PHI and may use it to develop new tests, procedures and 
commercial products.  The study staff will assign a code number and/or letters 
to your child’s records, which means that your child will not ordinarily be 
identified in the records sent to the sponsor.  The sponsor may, however, look 
at your child’s complete study records that identify your child.  In addition, 
the sponsor may visit the study site to oversee the way the study is being 
conducted and may review your child’s PHI during these visits to make sure 
the information is correct.   
• The Institutional Review Board ("IRB") may have access to your child’s PHI 
in relation to its responsibilities as an Institutional Review Board. 
 
The study doctor or sponsor may disclose your child’s PHI to the United States 
Food and Drug Administration ("FDA") or similar regulatory agencies in the 
United States and/or foreign countries. 
 
These disclosures also help ensure that the information related to the research is 
available to all parties who may need it for research purposes. 
 
Except for the disclosures described above, your child’s PHI will not be shared 
with others unless required by law.  If your child’s PHI is given to the parties 
listed above and/or to others who are not required to comply with the federal law, 
your child’s PHI will no longer be protected by this law and could possibly be 
used or disclosed in ways other than those listed here.  
 
You have a right to see and make copies of your child’s PHI.  You are agreeing, 
however, by signing this document, not to see or copy some or all of your child’s 
PHI until the sponsor has completed all work related to this study.  At that time, 
you may ask to see your child’s records. 
 
This Authorization will expire 50 years from the date you sign it unless you 
revoke (cancel or withdraw) it sooner.   
 
You have a right to revoke your Authorization at any time.  If you revoke it, your 
child’s PHI will no longer be used for this study, except to the extent the parties 
to the research have already taken action based upon your Authorization or need

the information to complete analysis and reports for this research.  To revoke 
your Authorization, you must write to the study doctor, stating that you are 
revoking your Authorization to Use and Disclose Protected Health Information 
for your child.  If you revoke this Authorization, your child will not be allowed 
to continue to be in this study.   
 
You will receive a copy of this Authorization after you have signed it.

APPENDIX E: SAMPLE COLLECTION METHODS 
 
Blood Collection Methods 
 
1. Collect blood in a red top Vacutainer tube. 
2. Invert 8-10 times 
3. Allow to clot for 30-45 minutes at room temperature 
4. Centrifuge for 1,000 – 2,000 RPM for 10 minutes in a refrigerated centrifuge   
5. Pipette supernatant into cryovials in 0.2 ml aliquots, 
6. Store immediately at -70oC 
 
Urine Sample Collection 
 
A 24 hour urine specimen is required.  This is done by pooling all urine collected in a 24 hour 
period as described below. 
 
On the day of the collection, discard the first morning urine void, and begin the collection after 
this void. Collect all urine for the next 24 hours so that the morning urine void on the second 
day is the final collection. Measure and record this volume on the test request form and on the 
urine transport vial (see Pediatric Specimen Tubes below). Transfer a 10 ml volume into the 
labeled urine transport vial.  
 
Do not send the entire urine collection.

APPENDIX F: DSM-5 DIAGNOSTIC CRITERIA FOR AUTISM SPECTRUM 
DISORDER 
http://www.cdc.gov/ncbddd/autism/hcp-dsm.html  
 
Diagnostic Criteria for 299.00 Autism Spectrum Disorder 
A. Persistent deficits in social communication and social interaction across multiple 
contexts, as manifested by the following, currently or by history (examples are 
illustrative, not exhaustive; see text):  
1. Deficits in social-emotional reciprocity, ranging, for example, from abnormal 
social approach and failure of normal back-and-forth conversation; to reduced 
sharing of interests, emotions, or affect; to failure to initiate or respond to social 
interactions. 
2. Deficits in nonverbal communicative behaviors used for social interaction, 
ranging, for example, from poorly integrated verbal and nonverbal 
communication; to abnormalities in eye contact and body language or deficits 
in understanding and use of gestures; to a total lack of facial expressions and 
nonverbal communication. 
3. Deficits in developing, maintaining, and understand relationships, ranging, for 
example, from difficulties adjusting behavior to suit various social contexts; to 
difficulties in sharing imaginative play or in making friends; to absence of 
interest in peers. 
Specify current severity: 
Severity is based on social communication impairments and restricted, repetitive 
patterns of behavior. 
B. Restricted, repetitive patterns of behavior, interests, or activities, as manifested by at 
least two of the following, currently or by history (examples are illustrative, not 
exhaustive; see text):  
1. Stereotyped or repetitive motor movements, use of objects, or speech (e.g., 
simple motor stereotypes, lining up toys or flipping objects, echolalia, 
idiosyncratic phrases). 
2. Insistence on sameness, inflexible adherence to routines, or ritualized patterns 
of verbal or nonverbal behavior (e.g., extreme distress at small changes, 
difficulties with transitions, rigid thinking patterns, greeting rituals, need to take 
same route or eat same food every day). 

L1-79 for the Treatment of Autism 
Investigational New Drug Protocol 
 
 
Protocol No. HT 02-121 
Page - 60 - 
CONFIDENTIAL DOCUMENT 
3. Highly restricted, fixated interests that are abnormal in intensity or focus (e.g., 
strong attachment to or preoccupation with unusual objects, excessively 
circumscribed or perseverative interests). 
4. Hyper- or hyporeactivity to sensory input or unusual interest in sensory aspects 
of the environment (e.g. indifference to pain/temperature, adverse response to 
specific sounds or textures, excessive smelling or touching of objects, visual 
fascination with lights or movement). 
Specify current severity: 
Severity is based on social communication impairments and restricted, repetitive 
patterns of behavior. 
C. Symptoms must be present in the early developmental period (but may not become 
fully manifest until social demands exceed limited capacities, or may be masked by 
learned strategies in later life). 
D. Symptoms cause clinically significant impairment in social, occupational, or other 
important areas of current functioning. 
E. These disturbances are not better explained by intellectual disability (intellectual 
developmental disorder) or global developmental delay. Intellectual disability and 
autism spectrum disorder frequently co-occur; to make comorbid diagnoses of autism 
spectrum disorder and intellectual disability, social communication should be below 
that expected for general developmental level. 
Note: Individuals with a well-established DSM-IV diagnosis of autistic disorder, Asperger’s 
disorder, or pervasive developmental disorder not otherwise specified should be given the 
diagnosis of autism spectrum disorder. Individuals who have marked deficits in social 
communication, but whose symptoms do not otherwise meet criteria for autism spectrum 
disorder, should be evaluated for social (pragmatic) communication disorder. 
Specify if: 
• With or without accompanying intellectual impairment 
• With or without accompanying language impairment 
• Associated with a known medical or genetic condition or environmental factor 
• (Coding note: Use additional code to identify the associated medical or genetic 
condition.) 
• Associated with another neurodevelopmental, mental, or behavioral disorder 
• (Coding note: Use additional code[s] to identify the associated neurodevelopmental, 
mental, or behavioral disorder[s]. 
• With catatonia (refer to the criteria for catatonia associated with another mental 
disorder)
