"Bringing an important new therapy to orthopedic surgeons and patients is a significant milestone for Vericel, and I would like to thank the FDA for working closely with us to make MACI available for these patients," said Nick Colangelo, president and CEO of Vericel. "We believe that the introduction of MACI, along with investments to expand our commercial organization and implement new patient support programs, positions Vericel to generate significant growth in 2017 and beyond."Conference Call InformationToday's conference call will be available live at 9:00am (EST) in the Investors section of the Vericel website at http://investors.vcel.com/events.cfm.

About MACIMACI (autologous cultured chondrocytes on porcine collagen membrane) is an autologous cellular scaffold product that is indicated for the repair of symptomatic single or multiple full-thickness cartilage defects of the knee with or without bone involvement in adults. The MACI implant consists of autologous cultured chondrocytes seeded onto a resorbable Type I/III collagen membrane. Autologous cultured chondrocytes are human-derived cells which are obtained from the patient's own cartilage for the manufacture of MACI. Clinical DataThe FDA approval is supported by the results of SUMMIT trial 1, a Phase 3 two-year, prospective, multicenter, randomized, open-label, parallel-group study that enrolled a total of 144 patients, ages 18 to 54 years, with at least one symptomatic Outerbridge Grade III or IV focal cartilage defect on the medial femoral condyle, lateral femoral condyle, and/or the trochlea. The co-primary efficacy endpoint was change from baseline to Week 104 for the subject's Knee injury and Osteoarthritis Outcome Score (KOOS) in 2 subscales: Pain and Function (Sports and Recreational Activities [SRA]). 2 At Week 104, KOOS pain and function (SRA) had improved from baseline in both treatment groups, but the improvement was statistically significantly (p<0.001) greater in the MACI group compared with the microfracture group. In a responder analysis, the proportion of subjects with at least a 10-point improvement in both KOOS pain and function (SRA) was greater in the MACI ® group (63/72 = 87.5%; 95% CI [77.6%, 94.6%]) compared with the microfracture group (49/72 = 68.1%; 95% CI [56.0%, 78.6%]). The most frequently occurring adverse reactions (=5%) reported for MACI ® in the 2-year randomized, controlled clinical trial were arthralgia, tendonitis, back pain, joint swelling, and joint effusion. Serious adverse reactions reported for MACI were arthralgia, cartilage injury, meniscus injury, treatment failure, and osteoarthritis. Important Safety Information
- MACI is contraindicated in patients with a known history of hypersensitivity to gentamicin, other aminoglycosides, or products of porcine or bovine origin. MACI is also contraindicated for patients with severe osteoarthritis of the knee, inflammatory arthritis, inflammatory joint disease, or uncorrected congenital blood coagulation disorders. MACI is also not indicated for use in patients who have undergone prior knee surgery in the past six months, excluding surgery to procure a biopsy or a concomitant procedure to prepare the knee for a MACI implant.
- MACI is contraindicated in patients who are unable to follow a physician-prescribed post-surgical rehabilitation program.
- The safety of MACI in patients with malignancy in the area of cartilage biopsy or implant is unknown. Expansion of present malignant or dysplastic cells during the culturing process or implantation is possible.
- Patients undergoing procedures associated with MACI are not routinely tested for transmissible infectious diseases. A cartilage biopsy and MACI implant may carry the risk of transmitting infectious diseases to healthcare providers handling the tissue. Universal precautions should be employed when handling the biopsy samples and the MACI product.
- Final sterility test results are not available at the time of shipping. In the case of positive sterility results, health care provider(s) will be contacted.
- To create a favorable environment for healing, concomitant pathologies that include meniscal pathology, cruciate ligament instability and joint misalignment, must be addressed prior to or concurrent with the implantation of MACI.
- Local treatment guidelines regarding the use of thromboprophylaxis and antibiotic prophylaxis around orthopaedic surgery should be followed. Use in patients with local inflammations or active infections in the bone, joint, and surrounding soft tissue should be temporarily deferred until documented recovery.
- The MACI implant is not recommended during pregnancy. For implantations post-pregnancy, the safety of breast feeding to infant has not been determined.
- Use of MACI in pediatric patients or patients over 55 years of age has not been assessed.
- The most frequently occurring adverse reactions reported for MACI (=5%) were arthralgia, tendonitis, back pain, joint swelling, and joint effusion.
- Serious adverse reactions reported for MACI were arthralgia, cartilage injury, meniscus injury, treatment failure, and osteoarthritis.
