Known hypersensitivity to alprostadil or to any of the excipients of alprostadil based medicinal product.\n- Diseases: significant history of cardiovascular, skin, endocrine or neurological diseases or of active sexually transmitted diseases or of any other medical condition which may interfere with the aim of the study (including clinically significant abnormal ECG).\n- Pain perception: Limited or no pain perception, e.g. in the case of paraplegia or polyneuropathy (contraindication for vacuum assisted penile stretching).\n- Virology: known active hepatitis B or C, known immune deficiency disease (including human immunodeficiency virus [HIV]).\n- Medications: intake of tetracycline or their derivatives within 14 days before the screening.\n- Investigative drug studies: participation in the evaluation of any investigational product for 30 days before this study.\n- Blood donation: blood donations for 3 months before this study.\n- Sexual intercourse: subjects not engaging in sexual intercourse within 3 months prior to screening .\n- No comprehension: INABILITY to comprehend the full nature and purpose of the study, possible risks and side effects; INABILITY to co-operate with the Investigator and to comply with the requirements of the entire study including vacuum assisted penile stretching and home modelling exercises.\n- Underlying penis pathology: any condition affecting the penis, such as chordee in the presence or absence of hypospadias, thrombosis of the dorsal penile artery, infiltration by a benign or malignant mass or an infectious agent, significant erectile dysfunction that had failed to respond to oral treatment with phosphodiesterase type 5 inhibitors, priapism.\n- Curvature Measurement: failing erection that, in the opinion of the Investigator, is insufficient to accurately measure the subject’s penile deformity after administration of a prostaglandin E1-like drug (alprostadil).\n- Calcified Plaque: calcified plaque, as evident by appropriate penile ultrasound preventing a proper injection of the study treatment, with the exclusion of a non-contiguous stippling of calcium, provided that calcium deposit does not interfere with the injection of collagenase into the plaque; Peyronie’s plaques that involve the penile urethra, due to potential risk to this structure.\n- Hourglass Deformity: isolated hourglass deformity of the penis.\n- Proximal Plaque: plaque causing curvature of the penis located proximal to the base of the penis, so that the injection of the local anaesthetic could interfere with the injection of collagenase into the plaque.\n- Peyronie’s Disease treatments: receiving or planning to undergo any other treatment of the Peyronie’s Disease during the study period, including but not limited to any surgery before and during the study, oral/topical agents within 3 months, intralesional medical therapies within 3 months, extracorporeal shock wave therapy within 6 months, use of mechanical devices within 2 weeks.\n- Baseline Hemodynamic: a penile duplex Doppler ultrasound evaluation at screening that shows compromised penile hemodynamic that, in the opinion of the Investigator, is clinically significant.\n- Bleeding and anticoagulants: history of bleeding, coagulation disorders, anticoagulant or antiaggregant therapy within 7 days of the screening with the exception of low daily intake of acetylsalicylic acid (100 mg/die)."}
