	non-GLP
study with no QA oversight - Pilot T cell ELISPOT project



Company
will:


		•	Use
                                         its own preferred carrier for shipments of materials to CTL.



		•	Provide
                                         thirty (30) peptides- test antigens (Ags).



		•	Provide
                                         up to thirty-nine (39) cryopreserved PBMC samples from different subjects with up to
                                         one time points.



CTL
will:


	Antigen preparation: CTL
will dissolve, pool, prepare and store working aliquots of the Company’s antigens for a fee. These synthesized antigens
are provided by the Company. Currently up to thirty (30) individual antigen preparations and one (1) peptide pool preparation
is assumed. Specifics on the antigens will be provided by the Company (e.g. sequence, purity, which Ags to be pooled etc.). In
the case that antigens are requested to be ordered by CTL, then CTL will be reimbursed by the Company (cost not included in the
work order).



 


	Optimization phase for ELISPOT:
CTL will optimize the antigen-specific triple color fluorescent IFN-gamma/ Granzyme B/ IL-5 ELISPOT assay for the testing
of human samples using the Company’s antigens of interest.



 


	Step 1: Screening-small titration
of the up to thirty-nine (39) cryopreserved positive responders PBMC in three Ag concentrations (e.g. 100 ug/ml, 25 ug/ml and
2.5 ug/ml) per provided antigen.



 


	The supernatant (SN) from IFN-gamma/Granzyme
B/IL-5 ELISPOT plate will be collected, frozen and stored until further instructions have been received by the Company.



 


	Step 2: Titration of the Ags in
the IFN-gamma/Granzyme B/IL-5 ELISPOT assay on up to four (4) antigen positive identified samples to define correct Ag concentration
to be used for each Ag.



 


	Step 3: Screening of thirty (30)
purchased sample(s) from CTL ePBMC® library with the thirty (30) antigens at one concentration, in the recall antigen
specific IFN-gamma/ Granzyme B/ IL-5 ELISPOT assay using one (1) sample per plate.



 


	Step 4: Titration of the one (1)
peptide pool in the IFN-gamma/Granzyme B/IL-5 ELISPOT assay on up to four (4) selected samples to define Ag concentration to be
used.



 


	Step 5: Final assay set up for
clinical sample testing- using selected four (4) positive samples and up to six (6) test antigens in the recall antigen specific
IFN-gamma/ Granzyme B/ IL-5 ELISPOT assay, whereby the test antigens are comprised of one (1) peptide pool and up to five (5)
individual peptides at one (1) concentration



 


		•	Human
                                         samples from CTL ePBMC® library used will contains approximately 1 x 107
                                         cells per vial.



 


	A CTL Development Report will
be generated once the Pilot study has been finalized.



 


		•	Additional
                                         optimization experiments (with input from Company before each experiment would be initiated)
                                         might be performed, however than an Amendment to this Work Order will need to be prepared.



 


		•	Results
                                         from each experiment will be forwarded to the Company. Results will be presented in the
                                         form of an Excel workbook, including among others, viability and recovery of cells, and
                                         mean and standard deviation of the spot counts, with a brief (1-2 pages) Internal Experimental
                                         Report that will summarize the results of the experiment performed.



 


	This phase of the study is a non
GLP study; however, if QA oversight would be requested by the Company, an additional 10% fee on all included activities (but not
supplies) would be incurred. If this option would be chosen, then CTL, Quality Assurance will inspect this non-regulated study,
which will include inspection of the raw data and final draft report. No QA Statement will be included in the final development
report, but records of inspection will be maintained with CTL QA.



 


		•	Overtime
                                         and weekend work will be billed as incurred for the ELISPOT assays.



 


		•	Short
                                         Term Storage: For the month in which the sample or antigen vial is received, storage
                                         is free. Thereafter a storage fee per vial will apply as incurred.



 


		•	Store
                                         the cryopreserved samples under liquid nitrogen vapor. CTL staff will enter specimen
                                         information into its sample management database in accordance with CTL standard operating
                                         procedures (SOPs). Long term storage of cryopreserved samples will incur a placement
                                         and a pulling fee per vial and a storage fee per vial per month as outlined in the attachment.



		•	Provide
                                         M.D./Ph.D. consultation at a rate of $250/hour.



 


		B.	General
                                         Provisions



 


		•	If
                                         Company later desires CTL to accelerate (rush) the schedule for any of the services to
                                         be rendered by CTL under the agreement or applicable work order, CTL will attempt to
                                         find a mutually agreeable modification of the schedule to accommodate Company’s
                                         request. However, CTL’s ability to meet such a request may depend upon the complexity
                                         of services involved, the volume of work requested, the availability of materials and/or
                                         personnel needed to meet the request, and the time frame involved. An acceleration of
                                         the specified dates outlined in the agreement or work order may result in accelerated
                                         services surcharges based upon the aforementioned factors.



 


		•	CTL
                                         Consumables: CTL has available multiple consumables for standardization of the assay
                                         performed at CTL. These include: vials of isolated and cryopreserved PBMC from a large
                                         batch (single time point), serum-free media (wash, test, and freezing media), peptides,
                                         control antigens, and protocols and training for the processing/cryopreservation of PBMC.
                                         All are available upon request and will be charged separately if incurred.



 


	CTL could offer the consultation
services of its staff for the support of the study and interpretation and management of the data. This includes biostatisticians,
PhD’s, technicians, etc.



 


		•	All
                                         records generated by CTL will be scanned. The Company will be given the option to request
                                         all materials to be shipped to a defined location or the records generated by CTL will
                                         be retained at CTL for two (2) years from the study completion date and signed final
                                         report. After two (2) years have elapsed, the Company will be contacted for further instructions
                                         and, if additional storage of records is requested, additional charges will be incurred.
                                         All records generated by CTL could be retained at CTL for two (2) years from the study
                                         completion date for no additional fee. Additional storage could be accommodated for a
                                         fee of $43.00 per inch binder per month.



 


		•	ELISPOT
                                         plates will be discarded after experimental data has been approved by the CTL Study Director/Responsible
                                         Scientist/ PI.



 


		•	Sample
                                         vials stored at CTL incur the storage fee per vial per month starting 1 month after their
                                         arrival. After completion of the study and the final report has been signed, samples,
                                         antigens and aliquots will be stored at CTL for up to four (4) weeks. CTL will send written
                                         instructions to the Company regarding onward shipping or disposal of the samples and
                                         aliquots stored at CTL. If onward shipping is requested or further storage by the Company,
                                         additional charges might occur.



 


	After two (2) years have elapsed,
CTL will make three (3) contacting attempts by mail or e-mail. If the Company will not respond to CTL within 30 days of the third
attempt, then this will automatically authorize CTL to discard the remaining study records, materials and samples pertaining to
this study.
