Intervention(s):

CIMAvax-EGF group (Experimental). The patients will receive 8 administrations of the product. Every administrationwill have a dose of 2.4 mg of the active principle of the therapeutic vaccine CIMAvax-EGF® (rhEGF-rP64k conjugate) in 1.2 mL of the injection (vaccine in aqueous phase plus Montanide ISA 51 VG) intramuscularly. The total dose will be divided into 4 subdoses, equivalent to 0.6 mg of EGF at each site of inoculation (both deltoid regions and both glutes). During the induction phase they will receive 4 administrations, one every 14 days. They will then receive 4 doses during the maintenance phase, one dose every 28 days, until 6 months of treatment are completed. Patients in this group will additionally receive the best supportive therapy available, which may include: steroids (depending on the type of respiratory disorder and medical criteria, without exceeding a total daily dose of 60 mg / day for 14 days and / or weekly gradual reduction), bronchodilators, antibiotics in case of infection, hypotensive drugs in case of pulmonary hypertension, medicines for heart failure in case of cor pulmonale, oxygen therapy and / or pulmonary rehabilitation. Control group: Patients in this group will receive the best supportive therapy available, which may include: steroids (depending on the type of respiratory disorder and medical criteria, without exceeding a total daily dose of 60 mg / day for 14 days and / or weekly gradual reduction), bronchodilators, antibiotics in case of infection, hypotensive drugs in case of pulmonary hypertension, medicines for heart failure in case of cor pulmonale, oxygen therapy and / or pulmonary rehabilitation. In each group the patients will be divided into two subgroups: Subgroup 1: Patients with post-COVID-19 pulmonary fibrosis Subgroup 2: Patients with another post-COVID-19 respiratory disorder not pulmonary fibrosis

Intervention code:

Immunotherapy, Active

Epidermal Growth Factor

Outcomes and Timepoint

Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.

Primary outcome(s):

Response to treatment (It will measure through the variation of forced vital capacity (FVC) in the categories favorable or unfavorable. It will be considered Favorable response when FVC does not vary or is reduced by less than 10% in patients with pulmonary fibrosis and does not vary or is reduced by less than 5% in patients with another respiratory disorder with respect to the initial measurement. Unfavorable response: when FVC is reduced more than 10% with respect to the initial measurement in patients with pulmonary fibrosis, and more than 5% in patients with another respiratory disorder). Measurement time: days 63 and 182.

Key secondary outcomes:

Safety: 1. Occurrence of any AE (Yes, No). Measurement time: 6 months. 2. Adverse event description (Name of the adverse event). Measurement time: 6 months. 3. Duration of the adverse event (Difference between the start date and the stop of the event). Measurement time: 6 months. 4. Intensity of AE (1. Light, 2. Moderate 3. Severe, 5. Very severe 5. Death, according to Common Toxicity Criteria (CTCAE) version 5.0). Measurement time: 6 months. 5. Causality relationship (.Definitive, 2.Very likely, 3.Likely, 4.Possible, 5.Unlikely, 6.Unrelated, 7.Unknown). Measurement time: 6 months. 6. Gravity (Seriousness) of AE (Critical event / No serious. Serious event (seriously) be considered as causing the death of the patient, life-threatening, results in hospitalization or prolongation of existing hospitalization, causes disability / persistent or significant disability, birth defects or congenital anomalies or an important medical event that according to medical judgment, could endanger the health of the patient or may require medical or surgical intervention to prevent the occurrence of any of the previously listed outcomes). Measurement time: 6 months. 7. Attitude towards drug (1. No change 2. Dose reduction 3. Temporary discontinuation of treatment. 4. Definitive Treatment discontinuation). Measurement time: 6 months. 8. Outcome of the AE (1. Reversible effect, 2. Effect 3. Death 4. Irreversible loss of patient monitoring). Measurement time: 6 months. Effect: 1. Maximum expiratory volume-VEM (It is the fraction of the forced vital capacity that can expire in the first second in a forced expiration after a maximum inspiration, observed value in ml). Measurement time: days 0, 63 and 182. 2. Number of lesions (number of lesions that the patient presents at each moment of evaluation, measured by CT). Measurement time: days 0, 63 and 182. 3. Type of lesion (nonspecific pulmonary fibrosis, tarnished virio pattern, reticulo-nodular pattern, or other). Measurement time: days 0, 63 and 182. 4. Lesion location: In the right lung (Upper lobe: anterior, posterior or apical, Middle lobe: medial or lateral, or Lower lobe: apical, anterior, posterior, internal, external). In the left lung (Upper lobe: apical posterior, anterior, superior lingular, inferior lingular, Lower lobe: apical, anterior, posterior, external. Measurement time: days 0, 63 and 182. 5. Extension of the lesion: Area of the lesion in cm2. Measurement time: days 0, 63 and 182. 6. Modification of the measurable lesion according to extension: (increase, no variation or reduction). Measurement time: days 0, 63 and 182. 7. Number of affected segments for non-measurable lesions (number of affected segments). Measurement time: days 0, 63 and 182. 8. Variation of the non-measurable lesion (increase, no variation or reduction). Measurement time: days 0, 63 and 182. 9.
