The validation will verify the previous validation results for steps 1 and 2 with a 1.5 time batch size increase in these steps and to demonstrate that control of crystallization will consistently produce polymorphic form III of pleconaril. - -------------------------------------------------------------------------------- May 22, 2001 Exhibit 1.20 Page 4 Protocol number Process Validation Protocol-PLECONARIL-DATE 4 NUMBER OF VALIDATION BATCHES The validation will be carried out on all three (3) steps of the synthesis on the new production campaign. The relevant data will be collected for all the batches produced during that additional campaign. The campaign will consist in 5 batches of both 1st and 2nd steps and 4 batches of the 3rd step. After completion of each batch, the batch record will be reviewed to determine the effect of any modifications and/or deviations to the procedure described in the applicable Master Batch Record (MBR) on the validation. For a successful validation, at least three (3) consecutive batches of each step will be produced without deviations of the critical process parameters. In addition, the three consecutive batches of each step must conform to the critical quality attributes. If any step requires modifications to the process and MBR, this validation protocol will be amended and additional batch(es) will be produced so that the validation includes three consecutive batches by the amended process and if a validation batch fails for reasons unrelated to process performance (e.g., power failure or equipment or equipment breakdown), that batch will be removed from the validation study and an additional batch will be produced, which will be considered consecutive to the batch preceding the batch that failed for non-process related reasons. 5 QUALITY OF MATERIALS Only fresh, not recovered, solvents are used . All reagents, solvents and other materials used in this validation will meet their currently approved specifications. 6 PROCESS DESCRIPTION STEP 1: PREPARATION OF *********** (**************) ************** STEP 2: PREPARATION OF *********** (**************) ************** STEP 3: PREPARATION OF *********** (**************) ************** - -------------------------------------------------------------------------------- May 22, 2001 Exhibit 1.20 Page 5 Protocol number Process Validation Protocol-PLECONARIL-DATE 7 PROCESS EQUIPMENT Major equipment used for the manufacture of pleconaril is specified in the batch record.

Any specific sampling is indicated in the batch instructions. The proposed sampling plan for the validation batches is as follows: PROCESS STEP 1 . IPC#203-1 Samples taken and analyzed at *********** hours to profile completion of reaction. When IPC#203-1 results are ********% ***********, then the reaction will be cooled and no further samples taken. The IPC results from all three validation batches will be evaluated in conjunction with previous pilot and production batches to confirm that the target reaction time is consistently between ******** hours. . At least three samples are taken from each batch (first centrifuge shot, half-way through-centrifugation and last centrifuge shot) and each sample analyzed individually for impurities (method no. 61834.000) to evaluate efficiency of the washing procedure and an LOD (IPC 203-1.5) to evaluate centrifugation efficiency. PROCESS STEP 2 . After drying, a representative sample from the first drum, middle drum and last drum of total number of drums will be taken and each sample analyzed individually for water content (IPC#203-3). PROCESS STEP 3 .

A validation report will be written. The final review and the approval of the validation report will be carried out by the functions involved for the approval of the present protocol as defined in section 2. The validation report will include the following, at a minimum: Copy of the Control Sheets of the Executed Batch Records. o Listing of all modifications and deviations from the MBR for each batch for each step, as well as an evaluation of the impact on the validation of each modification and deviation. - -------------------------------------------------------------------------------- May 22, 2001 Exhibit 1.20 Page 11 Protocol number Process Validation Protocol-PLECONARIL-DATE o Table listing steps with defined process parameters, the acceptance criteria for each listed process parameter, the actual conditions for those parameters for each batch and an evaluation as to whether the actual conditions met the acceptance criteria. o Tables with the analytical results of the testing in the quality specifications for Intermediates and pleconaril, as well as an evaluation as to whether each batch met the acceptance criteria. o Evaluation to determine that each step met all acceptance criteria and is considered validated. o Conclusions. The complete validation file will contain the above validation report and all documentation collected. 12 VALIDATION ACCEPTANCE CRITERIA The validation acceptance criteria are as follows: o Acceptance of each executed batch record demonstrating that the process parameters have been met within the defined ranges. o The two starting materials, two intermediates and the final API will meet all specification acceptance criteria as outlined in section 8. o The following samples described under the sampling plan section will meet the following acceptance criteria: 12.1. PROCESS STEP 1: . IPC 203-1 Samples: IPC 203-1 results are ********% ***********. The IPC results from all three validation batches will be evaluated in conjunction with previous pilot and production batches to confirm that the target reaction time is consistently ****** hours. . Centrifuge Shots: Each sample will be analyzed for residual solvents by LOD (IPC 203-1.5). Acceptance criteria: Any individual LOD value across all batches will not be ************%. 12.2. PROCESS STEP 2: . IPC 203-2 Samples: IPC 203-2 results are *********% *************. . Samples from Dryer: Each sample will be analyzed using the most current version of the water content method (IPC#203-3). Acceptance criteria: Water content ********% - -------------------------------------------------------------------------------- May 22, 2001 Exhibit 1.20 Page 12 Protocol number Process Validation Protocol-PLECONARIL-DATE 12.3. PROCESS STEP 3: . Samples from the Dryer: The samples are analyzed according to the plan given in section 10 - process step 3. The samples will validate - Purity, polymorphic form at "middle" (about 24 hours), end of drying and after sieving - That the IPC will determine end of drying and batch homogeneity. The intention of this plan is not to validate a certain drying time. . Samples from Drums: Each sample will be analyzed using the most current version of methods listed in section 8.4. Acceptance criteria: Each sample must meet all specifications acceptance criteria listed in section 8.4. of this protocol. . The analytical results on both samplings will be evaluated for the incidence of drying and sieving on the polymorphysm and on the impurities profile. 13 PROCESS VALIDATION FAILURE If any step fails to meet the process validation criteria specified in Section 12, an investigation will be carried out to determine the cause of the failure. If necessary, additional developmental work may be carried out. Based on the results of the investigation and any additional work, this protocol will be amended to describe the additional work required to complete the validation. - -------------------------------------------------------------------------------- May 22, 2001 Exhibit 1.20 Page 13 Protocol number Process Validation Protocol-PLECONARIL-DATE
